Description

The embodiments disclosed in this specification and drawings relate to an ultrasound diagnostic system.

Conventionally, ultrasound probes such as transesophageal ultrasound probes and laparoscopic ultrasound probes have a bending section at the tip that can be bent left and right. Medical professionals, such as doctors, bend the bending section to any angle by operating a rotating handle on the ultrasound probe with one or both hands.

However, medical professionals perform a variety of operations beyond bending the bending area, so improved operability is required.

An ultrasound diagnostic system according to an embodiment will be described below with reference to the drawings. In the following embodiments, parts with the same reference numerals perform similar operations, and duplicate descriptions will be omitted where appropriate.

Figure 1 is a block diagram showing an example configuration of an ultrasound diagnostic system 1 according to the first embodiment. As shown in Figure 1, the ultrasound diagnostic system 1 includes an ultrasound probe 100, a device main body 200, a display 300, an input interface 400, a first foot operation device 500, and a second foot operation device 600. The ultrasound probe 100, the display 300, and the input interface 400 are communicatively connected to the device main body 200 via wires. Furthermore, the first foot operation device 500 and the second foot operation device 600 are communicatively connected to the device main body 200 via short-range wireless communication.

The ultrasound probe 100, display 300, and input interface 400 may be communicatively connected to the device main body 200 via short-range wireless communication. Furthermore, the first foot operation device 500 and the second foot operation device 600 may be communicatively connected to the device main body 200 via a wired connection.

The ultrasound probe 100 is inserted into the subject. For example, the ultrasound probe 100 is a transesophageal probe. The ultrasound probe 100 is used to acquire ultrasound images of the heart, for example, from the esophagus. Note that the ultrasound probe 100 is not limited to a transesophageal probe, and may also be a laparoscopic probe for laparoscopy or other probes.

The ultrasound probe 100 has multiple transducers. These multiple transducers generate ultrasound waves based on drive signals supplied from a transmission/reception circuit 132 included in the device main body 200. The ultrasound probe 100 also receives reflected waves from the subject and converts them into electrical signals. The ultrasound probe 100 is detachably connected to the device main body 200.

When ultrasound waves are transmitted from the ultrasound probe 100 to the subject, they are reflected successively by discontinuous surfaces of acoustic impedance in the subject's internal tissues and received as reflected wave signals by the multiple transducers of the ultrasound probe 100. The amplitude of the received reflected wave signals depends on the difference in acoustic impedance at the discontinuous surfaces from which the ultrasound waves are reflected. When the transmitted ultrasound pulse is reflected by the surface of a moving blood flow, heart wall, or the like, the reflected wave signal undergoes a frequency shift due to the Doppler effect, depending on the velocity component of the moving object relative to the direction of ultrasound transmission.

Figure 2 is a diagram showing an example of the appearance of the ultrasound probe 100 according to the first embodiment. In the first embodiment, a Cartesian coordinate system consisting of the X1 axis, Y1 axis, and Z1 axis is defined for the ultrasound probe 100. The Y1 axis direction is a direction parallel to the longitudinal direction of the ultrasound probe 100. The X1 axis direction is a first direction in which the bending portion 112 bends, and is a direction perpendicular to the Y1 axis direction and the Z1 axis direction. The Z1 axis direction is a second direction perpendicular to the first direction in which the bending portion 112 bends, and is a direction perpendicular to the X1 axis direction and the Y1 axis direction.

The ultrasound probe 100 comprises an insertion section 110 and an operation section 120.

The insertion section 110 is a tubular member that is inserted into the subject. The insertion section 110 is covered with an exterior member. The insertion section 110 also has a tip section 111 and a bending section 112.

The tip section 111 is provided at the tip of the insertion section 110. The tip section 111 also includes a transducer section 131 (see Figure 5) that has multiple transducers. The insertion section 110 has a cable inside the exterior member that transmits reflected wave signals received by the multiple transducers.

The bending portion 112 is provided on the insertion portion 110 and bends the insertion portion 110 in response to an angle change operation received by the first operation portion of the first foot operation device 500. More specifically, the bending portion 112 is positioned closer to the operation portion 120 than the tip portion 111. The bending portion 112 changes the direction of travel of the insertion portion 110 by bending. The bending portion 112 bends in the left-right direction, which is a first direction. That is, the bending portion 112 bends in the X1-axis direction. Furthermore, the bending portion 112 bends in the up-down direction, which is a second direction perpendicular to the first direction. That is, the bending portion 112 bends in the Z1-axis direction. The bending portion 112 includes a bellows-shaped bellows member and a wire that pulls the bellows member. The wire stretches and contracts the bellows member by pulling the bellows member. In this way, the bending portion 112 bends due to the expansion and contraction of the bellows member.

The operation unit 120 is the part held by an operator, such as a doctor. The operation unit 120 also has multiple operation buttons 121 that accept various operations.

Returning to Figure 1, the input interface 400 accepts various instructions and information input operations from the operator. Specifically, the input interface 400 converts the input operations accepted by the operator into electrical signals and outputs them to the processing circuit 270 (see Figure 5) of the device main body 200. For example, the input interface 400 may be implemented by a trackball, switch buttons, a mouse, a keyboard, a touchpad that performs input operations by touching the operation surface, a touchscreen that integrates a display screen and a touchpad, a non-contact input circuit that uses an optical sensor, and a voice input circuit. Note that the input interface 400 is not limited to those equipped with physical operating components such as a mouse and keyboard. For example, an electrical signal processing circuit that receives electrical signals corresponding to input operations from an external input device provided separately from the device and outputs these electrical signals to a control circuit is also included as an example of the input interface 400.

The display 300 displays various types of information and images. Specifically, the display 300 converts information and image data sent from the processing circuitry 270 into electrical signals for display and outputs them. For example, the display 300 may be implemented as an LCD monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like. Note that the output device provided in the ultrasound diagnostic system 1 is not limited to the display 300 and may include, for example, a speaker. For example, the speaker outputs a predetermined sound, such as a beep, to notify the operator of the processing status of the device main body 200.

The first foot operation device 500 and the second foot operation device 600 are devices that accept operation of the ultrasound probe 100 by the operator's feet. In the first embodiment, a Cartesian coordinate system consisting of the X2 axis, Y2 axis, and Z2 axis is defined in the first foot operation device 500 and the second foot operation device 600. The X2 axis direction is parallel to the longitudinal direction of the first foot operation device 500 or the second foot operation device 600. The Y2 axis direction is parallel to the lateral direction of the first foot operation device 500 or the second foot operation device 600. The Z2 axis direction is perpendicular to the X2 axis direction and the Y2 axis direction, and is perpendicular to the sole portion 520.

The first foot operation device 500 and the second foot operation device 600 accept operations on the ultrasound probe 100. The first foot operation device 500 is an example of a first operation device. The second foot operation device 600 is an example of a second operation device. For example, the first foot operation device 500 and the second foot operation device 600 have a shape similar to footwear worn on the feet, such as shoes or slippers.

Figure 3 is an explanatory diagram showing an example configuration of a first foot operating device 500 according to the first embodiment. The first foot operating device 500 comprises an upper part 510 that covers the instep of the foot, and a sole part 520 that forms the bottom surface of the first foot operating device 500. The upper part 510 is a member for attaching the first foot operating device 500 to the operator's foot. The sole part 520 comprises a contact part 521, a rotating body 522, a gear 523, a first vibration part 524, an encoding part 525, a communication part 526, and a second vibration part 527.

The contact portion 521, the rotation axis 5222, and the encoding portion 525 accept angle change operations performed by the operator's foot. The contact portion 521, the rotation axis 5222, and the encoding portion 525 are an example of a first operating portion. The contact portion 521 is a disk-shaped member that comes into contact with the ground. The contact portion 521 is formed at a position corresponding to the operator's heel when the first foot operating device 500 is worn. The contact portion 521 is formed from a material with high friction, such as rubber. Note that the contact portion 521 is provided separate from the bottom surface of the sole portion 520.

The rotating body 522 has a fringe portion 5221. The fringe portion 5221 of the rotating body 522 is adhered to the contact portion 521. The rotating body 522 has a rotation axis 5222 that is approximately perpendicular to the contact portion 521 and located approximately in the center of the contact portion 521. The rotation axis 5222 is an example of a first rotation axis. The rotating body 522 is supported rotatably relative to the sole portion 520. The rotating body 522 rotates around the rotation axis 5222, which is approximately perpendicular to the ground. This allows the rotating body 522 to change its angle using the operator's foot.

Gear 523 is a member with irregularities on its periphery. Gear 523 is attached to rotation shaft 5222 of rotating body 522. Gear 523 rotates integrally with rotation shaft 5222 of rotating body 522.

The first vibrating part 524 generates vibrations when the rotating body 522 rotates. The first vibrating part 524 is a component such as a ball plunger. The first vibrating part 524 is pressed against the gear 523 and is fixed to the sole part 520. When the gear 523 rotates, the first vibrating part 524 moves the ball at the tip of the ball plunger in and out due to the unevenness of the gear 523. In this way, the first vibrating part 524 positions the gear 523 and generates vibrations due to the restoring force of the elastic body as the ball moves in and out.

The encoding unit 525 acquires the angle of rotation around the rotation axis 5222 as an angle change operation. The encoding unit 525 is an example of a first acquisition unit. More specifically, the encoding unit 525 acquires the angle by which the first foot operating device 500 has rotated around the rotation axis 5222. For example, the encoding unit 525 acquires the angle by which the first foot operating device 500 has rotated by optically reading a scale provided on the rotating body 522. The encoding unit 525 then generates rotation angle information indicating the angle by which the first foot operating device 500 has rotated around the rotation axis 5222.

The second vibration unit 527 generates vibration when the first operation unit receives a change operation that changes the angle by more than a threshold value. For example, the second vibration unit 527 is a motor with a weight with an offset center of gravity attached to an axis. The second vibration unit 527 generates vibration by rotating the axis. For example, the second vibration unit 527 generates vibration when the communication unit 526 receives vibration request information.

The communication unit 526 communicates with the device main body 200. For example, the communication unit 526 transmits rotation angle information generated by the encoding unit 525 to the device main body 200. The communication unit 526 also receives vibration request information from the device main body 200 that requests vibration of the second vibration unit 527.

The operator rotates the heel around the rotation axis 5222 while pressing the contact part 521 against the ground. Here, the rotating body 522 is rotatably supported, but does not rotate because it is pressed against the contact part 521. On the other hand, the sole part 520 rotates around the rotation axis 5222 of the rotating body 522 because the rotating body 522 is rotatably supported.

In addition, as the gear 523 rotates in response to the rotation of the rotor 522 around its axis, the first vibration unit 524 moves the ball at its tip in and out due to the unevenness of the gear 523. As a result, the first vibration unit 524 generates vibrations when the rotor 522 rotates. In other words, the first vibration unit 524 generates vibrations when the first operating unit receives an angle change operation. This allows the operator to understand that the rotation is being caused to occur around the rotation axis 5222.

The first foot operating device 500 also transmits the rotation angle information generated by the encoding unit 525 to the device main body 200. This allows the first foot operating device 500 to input the angle of the first foot operating device 500 to the device main body 200.

Furthermore, when the device main body 200 determines from the rotation angle information that the angle of rotation around the rotation axis 5222 is equal to or greater than a threshold value, the first foot operated device 500 receives vibration request information from the device main body 200. Then, when the vibration request information is received, the second vibrator vibrates. This allows the operator to know to what angle the first foot operated device 500 has been rotated.

Figure 4 is an explanatory diagram showing an example configuration of the second foot operating device 600 according to the first embodiment. The second foot operating device 600 comprises an upper part 610 that covers the instep of the foot, and a sole part 620 that forms the bottom surface of the second foot operating device 600. The upper part 610 is a member that is worn on the operator's foot.

The sole unit 620 includes a switch 621 and a communication unit 622. The switch 621 is provided on the upper surface of the sole unit 620 at a position that corresponds to the toes when the second foot operation device 600 is worn. The switch 621 accepts operation, for example, by being pressed. The communication unit 622 transmits switch information indicating that the switch 621 has been pressed to the device main body 200. This allows the second foot operation device 600 to input to the device main body 200 an operation indicating that the switch 621 has been pressed.

Furthermore, the first foot operation device 500 and the second foot operation device 600 may be formed for either the left or right foot of the operator. Furthermore, the switch 621 may be provided not only in the second foot operation device 600 but also in the first foot operation device 500.

Figure 5 is a block diagram showing a detailed example configuration of the ultrasound diagnostic system 1 according to the first embodiment.

The ultrasound probe 100 includes a transducer unit 131, a transmission/reception circuit 132, an operation button 121, a connection unit 134, a first drive unit 135, and a second drive unit 136.

The transducer unit 131 is provided in the insertion section 110 of the ultrasound probe 100 and has multiple transducers that transmit and receive ultrasound waves. For example, the transducer unit 131 has multiple transducers arranged in a row. The transducer unit 131 is also rotatably supported by the tip section 111. When multiple transducers are arranged in a row, the transducer unit 131 tilts the row of transducers by rotating it. Therefore, by rotating the transducer unit 131, the angle at which ultrasound waves are transmitted can be changed.

The transmission/reception circuit 132 includes a pulse generator, a transmission delay unit, a pulser, and the like, and supplies a drive signal to the ultrasonic probe 100. The pulse generator repeatedly generates rate pulses at a predetermined rate frequency to generate transmitted ultrasonic waves. The transmission delay unit focuses the ultrasonic waves generated from the ultrasonic probe 100 into a beam and provides a delay time for each transducer required to determine the transmission directivity to each rate pulse generated by the pulse generator. The pulser applies a drive signal (drive pulse) to the ultrasonic probe 100 at a timing based on the rate pulse. In other words, the transmission delay unit varies the delay time provided for each rate pulse to arbitrarily adjust the transmission direction of the ultrasonic waves transmitted from the transducer surface.

The transmission/reception circuit 132 also includes a preamplifier, an A/D (Analog to Digital) converter, a reception delay unit such as a quadrature detection circuit, an adder, etc., and performs various processes on the reflected wave signal received by the ultrasound probe 100 to generate reflected wave data.

The preamplifier amplifies the reflected wave signal for each channel and performs gain adjustment (gain correction). The A/D converter converts the gain-corrected reflected wave signal into a digital signal by A/D converting it. The quadrature detection circuit converts the A/D converted reflected wave signal into an in-phase signal (I signal, I: In-phase) and a quadrature signal (Q signal, Q: Quadrature-phase) in the baseband.

The quadrature detection circuit outputs I and Q signals as reflected wave data. Hereinafter, I and Q signals will be collectively referred to as IQ signals. Furthermore, since IQ signals are A/D converted digital data, they are also referred to as IQ data.

The receive delay unit provides the delay time required to determine the receive directivity. The adder generates reflected wave data by adding the reflected wave signals processed by the receive delay unit. The adder's addition process emphasizes the reflected components from the direction corresponding to the receive directivity of the reflected wave signal, and an overall ultrasonic beam is formed by the receive directivity and transmit directivity.

Here, the output signal from the transmission/reception circuit 132 can take a variety of forms, such as a signal containing phase information called an RF (Radio Frequency) signal, or amplitude information after envelope detection processing.

The connection unit 134 is an interface that connects the ultrasound probe 100 and the device main body 200 via a wired connection. For example, the connection unit 134 transmits ultrasound data generated by the transmission/reception circuit 132 to the device main body 200. When the operation button 121 is pressed, the connection unit 134 also transmits operation button information indicating that the operation button 121 has been pressed. Note that the connection unit 134 is not limited to a wired connection, and may also connect the ultrasound probe 100 and the device main body 200 wirelessly.

The first drive unit 135 generates power to bend the bending portion 112. For example, the first drive unit 135 is a drive device such as a motor. The first drive unit 135 pulls the wire of the bending portion 112 by performing an operation such as winding up the wire. In this way, the first drive unit 135 bends the bending portion 112.

The second drive unit 136 generates power to rotate the vibrator unit 131. For example, the second drive unit 136 is a drive device such as a motor. The second drive unit 136 pulls the wire of the vibrator unit 131 by winding it up or performing other operations. In this way, the second drive unit 136 rotates the vibrator unit 131.

The device main body 200 is a device that generates ultrasound images based on reflected wave signals received by the ultrasound probe 100. The device main body 200 also controls the ultrasound probe 100. For example, the device main body 200 generates two-dimensional ultrasound images based on two-dimensional reflected wave data received by the ultrasound probe 100. The device main body 200 also generates three-dimensional ultrasound images based on three-dimensional reflected wave data received by the ultrasound probe 100. The device main body 200 also controls the ultrasound probe 100.

As shown in FIG. 5, the device main body 200 has a connection unit 210, a signal processing circuit 220, an image generation circuit 230, a memory circuit 240, a network (NW) interface 250, a communication unit 260, and a processing circuit 270. The connection unit 210, the signal processing circuit 220, the image generation circuit 230, the memory circuit 240, the NW interface 250, the communication unit 260, and the processing circuit 270 are connected to each other so that they can communicate with each other.

The connection unit 210 is an interface that connects the ultrasound probe 100 and the device main body 200 via a wired connection. For example, the connection unit 210 receives ultrasound data from the ultrasound probe 100. The connection unit 210 also receives operation button information from the ultrasound probe 100. Note that the connection unit 210 is not limited to a wired connection, and may also connect the ultrasound probe 100 and the device main body 200 wirelessly.

The signal processing circuit 220 receives reflected wave data from the transmission/reception circuit 132 and performs processes such as logarithmic amplification and envelope detection to generate data (B-mode data) in which signal strength is expressed as brightness. The signal processing circuit 220 also performs frequency analysis of velocity information from the reflected wave data received from the transmission/reception circuit 132, extracts blood flow, tissue, and contrast agent echo components due to the Doppler effect, and generates data (Doppler data) that extracts moving object information such as velocity, dispersion, and power for multiple points.

The signal processing circuit 220 is also capable of processing both two-dimensional reflected wave data and three-dimensional reflected wave data. That is, the signal processing circuit 220 generates two-dimensional B-mode data from two-dimensional reflected wave data, and generates three-dimensional B-mode data from three-dimensional reflected wave data. The signal processing circuit 220 also generates two-dimensional Doppler data from two-dimensional reflected wave data, and generates three-dimensional Doppler data from three-dimensional reflected wave data.

The image generation circuit 230 generates an ultrasound image from the data generated by the signal processing circuit 220. For example, the image generation circuit 230 generates a two-dimensional B-mode image that represents the intensity of the reflected wave as brightness from the two-dimensional B-mode data generated by the signal processing circuit 220.

Also, for example, the image generation circuit 230 generates a two-dimensional Doppler image in which blood flow information is visualized from the two-dimensional Doppler data generated by the signal processing circuit 220. The two-dimensional Doppler image is velocity image data that represents the average velocity of the blood flow, variance image data that represents the variance value of the blood flow, power image data that represents the power of the blood flow, or image data that combines these. Furthermore, the image generation circuit 230 generates a color Doppler image in which blood flow information such as the average velocity, variance value, and power of the blood flow are displayed in color, or a Doppler image in which one piece of blood flow information is displayed in grayscale.

For example, the image generation circuitry 230 can also generate an M-mode image from the time series data of B-mode data on one scan line generated by the signal processing circuitry 220. The image generation circuitry 230 can also generate a Doppler waveform that plots blood flow and tissue velocity information in a time series from the Doppler data generated by the signal processing circuitry 220.

Here, the image generation circuit 230 generally converts (scan converts) the scan line signal sequence of the ultrasound scan into a scan line signal sequence in a video format, such as that used on a television, to generate an ultrasound image for display. Specifically, the image generation circuit 230 generates an ultrasound image for display by performing coordinate conversion according to the ultrasound scanning format used by the ultrasound probe 100. In addition to scan conversion, the image generation circuit 230 also performs various other image processing, such as image processing (smoothing processing) that regenerates an average brightness image using multiple image frames after scan conversion, and image processing (edge enhancement processing) that uses a differential filter within the image. The image generation circuit 230 also combines text information of various parameters, scales, body marks, etc., with the ultrasound image data.

In other words, the B-mode data and Doppler data are data before scan conversion processing, and the data generated by the image generation circuit 230 is image data for display after scan conversion processing. Hereinafter, the data before scan conversion processing (B-mode data and Doppler data) will also be referred to as "RAW data."

The image generation circuit 230 generates two-dimensional ultrasound images, such as two-dimensional B-mode images and two-dimensional Doppler images, from two-dimensional B-mode data and two-dimensional Doppler data, which are RAW data. The image generation circuit 230 can also generate superimposed images, for example, by superimposing a color Doppler image on a two-dimensional B-mode image.

The memory circuitry 240 stores various types of data. For example, the memory circuitry 240 stores control programs for transmitting and receiving ultrasound, image processing, and display processing, as well as various types of data such as diagnostic information (e.g., patient ID, doctor's findings, etc.), diagnostic protocols, and various body marks. For example, the memory circuitry 240 may be implemented using semiconductor memory elements such as RAM (Random Access Memory) and flash memory, a hard disk drive (HDD), an optical disk, etc.

In addition, the data stored in the memory circuitry 240 can be transferred to an external device via the NW interface 250. Examples of external devices include a personal computer (PC) or tablet terminal used by a doctor who performs image diagnosis, an image storage device that stores images, a printer, etc.

The NW interface 250 controls communication between the device main body 200 and external devices. Specifically, the NW interface 250 receives various information from external devices and outputs the received information to the processing circuit 270. For example, the NW interface 250 is realized by a network card, network adapter, NIC (Network Interface Controller), etc.

The communication unit 260 communicates with the first foot operation device 500 or the second foot operation device 600. For example, the communication unit 260 receives rotation angle information indicating the angle accepted by the first operation unit of the first foot operation device 500. The communication unit 260 is an example of a receiving unit. The communication unit 260 also transmits vibration request information to the first foot operation device 500. The communication unit 260 also receives switch information from the second foot operation device 600.

The processing circuitry 270 controls the overall processing of the ultrasound diagnostic system 1. Specifically, the processing circuitry 270 controls the operation of the connection unit 210, signal processing circuitry 220, and image generation circuitry 230 based on various setting requests input by the operator via the input interface 400 and various control programs and data read from the memory circuitry 240. The processing circuitry 270 also controls the display of ultrasound images.

The processing circuitry 270 also executes a drive control function 271, a vibration control function 272, and a display control function 273. Here, for example, each of the processing functions of the processing circuitry 270, namely, the drive control function 271, the vibration control function 272, and the display control function 273, are stored in the storage circuitry 240 in the form of a computer-executable program. The processing circuitry 270 is a processor. For example, the processing circuitry 270 realizes the function corresponding to each program by reading and executing the program from the storage circuitry 240. In other words, the processing circuitry 270 after reading each program will have each function shown in the processing circuitry 270 of FIG. 5. Note that, while FIG. 5 illustrates the processing functions performed by the drive control function 271, the vibration control function 272, and the display control function 273 being realized by a single processor, the processing circuitry 270 may also be configured by combining multiple independent processors, and each processor may realize the function by executing a program. Also, while FIG. 5 illustrates a single storage circuit 240 storing programs corresponding to each processing function, multiple storage circuits may be distributed and the processing circuit 270 may read corresponding programs from individual storage circuits.

The term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), GPU (Graphical Processing Unit), or an Application Specific Integrated Circuit (ASIC), a programmable logic device (e.g., a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA)). The processor achieves its functions by reading and executing a program stored in the memory circuitry 240. Note that instead of storing a program in the memory circuitry 240, the processor may be configured to directly incorporate the program into its circuitry. In this case, the processor achieves its functions by reading and executing the program embedded in the circuitry.

The drive control function 271 controls the drive of the first drive unit 135. That is, the drive control function 271 bends the bending portion 112 by driving the first drive unit 135. More specifically, the drive control function 271 controls the bending of the bending portion 112 based on the rotation angle information received from the first foot operation device 500. The drive control function 271 is an example of a bending control unit. The drive control function 271 determines the direction and angle of bending of the bending portion 112 based on the angle indicated in the rotation angle information. Then, the drive control function 271 bends the bending portion 112 by controlling the first drive unit 135 based on the rotation angle information. As a result, the bending portion 112 bends at the angle received by the first foot operation device 500 and in a direction corresponding to the angle.

Furthermore, when an axis switching operation is received, the drive control function 271 switches the axis that bends the bending section 112. As a result, when an axis switching operation that changes the bending direction is received, the bending section 112 bends in a direction different from that before the axis switching operation was received.

More specifically, the drive control function 271 switches from bending in the X1-axis direction, which is the left-right direction, to bending in the Z1-axis direction, which is the up-down direction. Alternatively, the drive control function 271 switches from bending in the Z1-axis direction, which is the up-down direction, to bending in the X1-axis direction, which is the left-right direction. An axis switching operation is, for example, an operation of pressing the switch 621 of the second foot operating device 600. That is, the switch 621 of the second foot operating device 600 accepts a press as an axis switching operation that changes the direction in which the bending portion 112 is bent. The switch 621 is an example of a second operating unit. Note that the axis switching operation is not limited to pressing the switch 621 of the second foot operating device 600, but may also be pressing the operation button 121 of the ultrasound probe 100, an operation accepted by the input interface 400, or some other operation.

The vibration control function 272 controls the vibration operation of the second vibration unit 527 of the first foot operating device 500. More specifically, when the vibration control function 272 receives rotation amount information from the first foot operating device 500, it determines whether to vibrate the second vibration unit 527 based on the received rotation angle information. For example, the vibration control function 272 determines whether the first foot operating device 500 has been rotated to an angle equal to or greater than a threshold based on the rotation angle information. Then, when the vibration control function 272 determines that the first foot operating device 500 has been rotated to an angle equal to or greater than the threshold, it causes the communication unit 260 to transmit vibration request information. Here, the angle equal to or greater than the threshold is not limited to one, and may be multiple. For example, the angle equal to or greater than the threshold is an angle in increments of 10 degrees. Alternatively, the threshold may be an angle set by the operator, etc.

The display control function 273 displays settings related to the operation of the ultrasound probe 100 using the first foot operation device 500 on the display 300. The display control function 273 is an example of a display control unit. For example, the display control function 273 displays the direction in which the bending portion 112 of the ultrasound probe 100 is to be bent. In other words, the display control function 273 displays whether the setting is for bending in the X1 axis direction, which is the left-right direction, or in the Z1 axis direction, which is the up-down direction.

Next, we will explain how to operate the ultrasound probe 100 using the first foot-operated device 500 and the second foot-operated device 600.

Figure 6 is a diagram showing an example of a method for operating the ultrasound probe 100 according to the first embodiment. As shown in Figure 6, the operator rotates the first foot operating device 500 around the rotation axis 5222. For example, the operator rotates the first foot operating device 500 45 degrees to the left. The encoding unit 525 of the first foot operating device 500 generates rotation angle information indicating the angle by which the first foot operating device 500 has rotated around the rotation axis 5222. In addition, the communication unit 526 of the first foot operating device 500 transmits the rotation angle information to the apparatus main body 200.

The communication unit 260 of the device main body 200 receives the rotation angle information. The drive control function 271 of the device main body 200 determines the direction and angle of bending of the bending portion 112 of the ultrasonic probe 100 based on the rotation angle information. The drive control function 271 then bends the bending portion 112 by controlling the first drive unit 135 of the ultrasonic probe 100. Figure 6 shows the bending portion 112 bent 45 degrees to the left.

Figure 7 is a diagram showing an example of a method of operating the ultrasound probe 100 according to the first embodiment. As shown in Figure 7, the operator presses the switch 621 of the second foot operation device 600. The communication unit 622 of the second foot operation device 600 transmits switch information indicating that the switch 621 has been pressed to the device main body 200. The connection unit 210 of the device main body 200 receives the switch information. The drive control function 271 of the device main body 200 also accepts the switch information as an axis switching operation. That is, the drive control function 271 switches the bending direction of the bending portion 112 from bending in the X1-axis direction, which is the left-right direction, to bending in the Z1-axis direction, which is the up-down direction.

As shown in FIG. 7, the operator rotates the first foot operation device 500 around the rotation axis 5222. In FIG. 7, the operator rotates the first foot operation device 500 45 degrees to the right. The encoding unit 525 of the first foot operation device 500 generates rotation angle information indicating the angle by which the first foot operation device 500 has rotated around the rotation axis 5222. In addition, the communication unit 526 of the first foot operation device 500 transmits the rotation angle information to the device main body 200.

The communication unit 260 of the device main body 200 receives the rotation angle information. The drive control function 271 of the device main body 200 determines the direction and angle of bending of the bending portion 112 of the ultrasound probe 100 based on the rotation angle information. Here, the drive control function 271 switches the direction of bending of the bending portion 112 to bending in the Z1 axis direction, which is the up-down direction. Therefore, the drive control function 271 controls the first drive unit 135 of the ultrasound probe 100 to bend the bending portion 112 in the Z1 axis direction, which is the up-down direction. In Figure 7, the bending portion 112 is bent downward by 45 degrees.

As described above, the ultrasound diagnostic system 1 according to the first embodiment includes an ultrasound probe 100 and a first foot operation device 500. The first foot operation device 500 accepts angle change operations performed by the operator's feet. The ultrasound probe 100 also has a bending section 112 attached to a tubular insertion section 110 inserted into a subject, which bends the insertion section 110 in response to angle change operations received by the first foot operation device 500. In this way, the ultrasound diagnostic system 1 accepts angle change operations performed by the operator's feet and bends the bending section 112. In other words, the ultrasound diagnostic system 1 now accepts operations performed by the feet, rather than by the hands, thereby reducing the burden on manual operations. Therefore, the ultrasound diagnostic system 1 can improve the operability of the ultrasound probe 100.

(Variation 1)
In the first embodiment, it has been described that the drive control function 271 bends the bending portion 112 by the same angle as the angle at which the first foot operation device 500 has rotated. In the first modification, the drive control function 271 bends the bending portion 112 by an angle different from the angle at which the first foot operation device 500 has rotated, in accordance with the operation.

When the drive control function 271 receives a ratio change operation, it changes the ratio of the angle at which the bending portion 112 is bent. The drive control function 271 receives, for example, switch information indicating that the switch 621 of the second foot operation device 600 has been pressed as a ratio change operation. That is, the switch 621 of the second foot operation device 600 receives the press as a ratio change operation that changes the ratio of the angle at which the bending portion 112 is bent relative to the angle received by the first operation unit. The switch 621 is an example of a third operation unit. Note that the ratio change operation is not limited to pressing the switch 621 of the second foot operation device 600, but may also be pressing the operation button 121 of the ultrasound probe 100, an operation received by the input interface 400, or some other operation.

For example, when a ratio change operation is received, the drive control function 271 doubles the ratio of the angle at which the bending portion 112 bends relative to the angle at which the first foot operation device 500 is rotated. As a result, when a ratio change operation is received that changes the ratio of the angle at which the bending portion 112 bends relative to the rotation received by the rotation axis 5222 of the first foot operation device 500, the bending portion 112 bends an angle according to that ratio.

For example, when a ratio change operation is received and the angle of the rotation operation received via the first foot operation device 500 is 22.5 degrees, the drive control function 271 bends the bending portion 112 by 45 degrees. Note that the ratio is not limited to 2x, but may be 3x or more, or may be set to any ratio. Furthermore, the ratio may be such that the angle at which the bending portion 112 is bent is reduced. For example, the ratio may be 1/2, 1/3, or less than 1/4.

The display control function 273 displays the ratio of the angle at which the bending portion 112 is bent relative to the angle received by the first operation unit of the first foot operation device 500. For example, the display control function 273 displays ratios such as 2x, 3x, 1/2, 1/3, and 1/4.

Figure 8 is a diagram showing an example of a method for operating the ultrasound probe 100 according to Variation 1. As shown in Figure 8, the operator presses the switch 621 of the second foot operating device 600. The communication unit 622 of the second foot operating device 600 transmits switch information indicating that the switch 621 has been pressed to the device main body 200. The connection unit 210 of the device main body 200 receives the switch information. The drive control function 271 of the device main body 200 also accepts the switch information as a ratio change operation. In other words, the drive control function 271 doubles the ratio of the angle at which the bending portion 112 bends relative to the angle at which the first foot operating device 500 has rotated.

As shown in FIG. 8, the operator rotates the first foot operation device 500 around the rotation axis 5222. In FIG. 8, the operator rotates the first foot operation device 500 22.5 degrees to the right. The encoding unit 525 of the first foot operation device 500 generates rotation angle information indicating the angle by which the first foot operation device 500 has rotated around the rotation axis 5222. In addition, the communication unit 526 of the first foot operation device 500 transmits the rotation angle information to the device main body 200.

The communication unit 260 of the device main body 200 receives the rotation angle information. The drive control function 271 of the device main body 200 determines the direction and angle at which the bending portion 112 of the ultrasound probe 100 is to be bent based on the rotation angle information. Here, the drive control function 271 doubles the ratio of the angle at which the bending portion 112 is bent to the angle at which the first foot operating device 500 is rotated. Therefore, the drive control function 271 bends the bending portion 112 45 degrees to the right by controlling the first drive unit 135 of the ultrasound probe 100.

As described above, the ultrasound diagnostic system 1 according to Modification 1 changes the ratio of the angle at which the bending portion 112 is bent to the angle received by the first foot operating device 500. This allows the operator to increase or decrease the angle at which the foot is bent relative to the rotation. Therefore, the ultrasound diagnostic system 1 according to Modification 1 can improve the operability of the ultrasound probe 100.

(Variation 2)
In the first embodiment, it has been described that the drive control function 271 bends the bending portion 112 by controlling the first drive unit 135. In the second modification, the drive control function 271 changes the target to be controlled to the second drive unit 136 in accordance with an operation.

When the drive control function 271 receives a target change operation, it changes the target to be controlled to the second drive unit 136. The drive control function 271 receives, for example, operation button information as the target change operation. That is, the operation button 121 of the ultrasound probe 100 receives a press as a target change operation to change the target operated by the first foot operation device 500. The operation button 121 is an example of a fourth operation unit. Note that the target change operation is not limited to pressing the operation button 121 of the ultrasound probe 100, but may also be pressing the switch 621 of the second foot operation device 600, an operation received by the input interface 400, or some other operation.

When an object change operation is received, the drive control function 271 controls the second drive unit 136 based on the rotation angle information, thereby controlling the rotation of the vibrator unit 131. The drive control function 271 is an example of a rotation control unit. In this way, the drive control function 271 rotates the vibrator unit 131. In other words, when an operation to change the object operated by the first foot operation device 500 is received, the vibrator unit 131 rotates according to the angle received by the first operation unit of the first foot operation device 500.

More specifically, when the drive target is set to the second drive unit 136 by a target change operation and rotation angle information is received from the first foot operating device 500, the drive control function 271 drives the second drive unit 136 based on the received rotation angle information. The drive control function 271 accepts, for example, operation button information as the target change operation.

The drive control function 271 determines the direction and angle of rotation of the vibrator unit 131 based on the angle indicated in the rotation angle information. The drive control function 271 then rotates the vibrator unit 131 in the determined direction and by the determined angle.

For example, the drive control function 271 rotates the vibrator unit 131 in the same direction as the rotation direction of the first foot operation device 500 and by the same angle as the angle by which the first foot operation device 500 has rotated. Furthermore, when the drive control function 271 receives a ratio change operation, it changes the ratio of the angle by which the vibrator unit 131 is rotated relative to the angle by which the first foot operation device 500 has rotated. For example, the drive control function 271 rotates the vibrator unit 131 by twice the angle by which the first foot operation device 500 has rotated.

The display control function 273 displays the object to be operated by the first foot operation device 500. For example, the display control function 273 displays whether the bending portion 112 or the vibrator portion 131 is the object to be operated by the first foot operation device 500.

Figure 9 is a diagram showing an example of a method for operating the ultrasound probe 100 according to Variation 2. As shown in Figure 9, the operator presses the switch 621 of the second foot operation device 600. The communication unit 622 of the second foot operation device 600 transmits switch information indicating that the switch 621 has been pressed to the device main body 200. The connection unit 210 of the device main body 200 receives the switch information. In addition, the drive control function 271 of the device main body 200 accepts the switch information as a ratio change operation.

As shown in FIG. 9 , the operator presses the operation button 121 of the ultrasound probe 100. The drive control function 271 accepts the operation button information as a target change operation. The drive control function 271 also accepts a ratio change operation. Therefore, the drive control function 271 doubles the ratio of the angle by which the transducer unit 131 is rotated to the angle by which the first foot operating device 500 is rotated.

As shown in FIG. 9, when the first foot operating device 500 is not rotating, the transducer unit 131 transmits ultrasound from the tip portion 111 at an angle of 90 degrees relative to the X1 axis direction.

As shown in Figure 9, when the first foot operation device 500 is rotated 45 degrees, the ratio of the angle at which the transducer unit 131 is rotated to the angle at which the first foot operation device 500 is rotated is twice as large, so the drive control function 271 rotates the transducer unit 131 90 degrees. As a result, the tip unit 111 transmits ultrasound from an angle of 0 degrees in the X1 axis direction.

As described above, the ultrasound diagnostic system 1 according to Modification 2 allows the operator to change the operation target using the operation button 121 of the ultrasound probe 100. In other words, the operator can operate various objects using their feet. Therefore, the ultrasound diagnostic system 1 according to Modification 1 can improve the operability of the ultrasound probe 100.

Second Embodiment
In the first embodiment, the first foot operation device 500 is described as rotating about the rotation axis 5222a of the rotating body 522 that is substantially perpendicular to the ground. However, the first foot operation device 500a may have a rotation axis 5222a that is substantially horizontal with respect to the pedal 528.

Figure 10 is an explanatory diagram showing an example configuration of a first foot-operated device 500a according to the second embodiment. The first foot-operated device 500a includes a pedal 528 and a rotating shaft 5222a. The pedal 528 is stepped on by the operator's foot. The rotating shaft 5222a rotatably supports the pedal 528 and is arranged approximately parallel to the pedal 528. The rotating shaft 5222a is an example of a second rotating shaft. A gear 523a is fixed to the end of the rotating shaft 5222a. Therefore, when the rotating shaft 5222a rotates, the gear 523a rotates.

The first vibrating part 524a is pressed against the gear 523a and is fixed to the sole part 520. When the gear 523a rotates, the first vibrating part 524a moves the ball at the tip in and out due to the unevenness of the gear 523a. This causes the first vibrating part 524a to generate vibrations.

The encoding unit 525a also acquires the angle of rotation around the rotation axis 5222a as an angle change operation. The encoding unit 525a is an example of a second acquisition unit. More specifically, the encoding unit 525a acquires the angle of rotation of the first foot operating device 500a by optically reading the scale provided on the gear 523a. The encoding unit 525a then generates rotation angle information indicating the angle of rotation of the pedal 528 of the first foot operating device 500a around the rotation axis 5222a.

Next, we will explain how to operate the ultrasound probe 100 using the first foot operation device 500a.

Figure 11 is a diagram showing an example of a method for operating the ultrasound probe 100 according to the second embodiment. As shown in Figure 11, the operator rotates the pedal 528 of the first foot-operated device 500a around the rotation axis 5222a. In Figure 11, the operator rotates the pedal 528 of the first foot-operated device 500a upward by 45 degrees.

The encoding unit 525a of the first foot operating device 500a generates rotation angle information indicating the angle by which the pedal 528 of the first foot operating device 500a has rotated around the rotation axis 5222a. The communication unit 526 of the first foot operating device 500a transmits the rotation angle information to the device main body 200.

The communication unit 260 of the device main body 200 receives the rotation angle information. The drive control function 271 of the device main body 200 determines the direction and angle of bending of the bending portion 112 of the ultrasound probe 100 based on the rotation angle information. The drive control function 271 then controls the first drive unit 135 of the ultrasound probe 100 to bend the bending portion 112. In Figure 12, the bending portion 112 is bent 45 degrees to the left.

Figure 12 is a diagram showing an example of a method for operating the ultrasound probe 100 according to the second embodiment. In Figure 12, the operator rotates the pedal 528 of the first foot-operated device 500a downward by 45 degrees.

The encoding unit 525a of the first foot operating device 500a generates rotation angle information indicating the angle by which the pedal 528 of the first foot operating device 500a has rotated around the rotation axis 5222a. The communication unit 526 of the first foot operating device 500a transmits the rotation angle information to the device main body 200.

The communication unit 260 of the device main body 200 receives the rotation angle information. The drive control function 271 of the device main body 200 determines the direction and angle of bending of the bending portion 112 of the ultrasound probe 100 based on the rotation angle information. The drive control function 271 then controls the first drive unit 135 of the ultrasound probe 100 to bend the bending portion 112. In Figure 12, the bending portion 112 is bent 45 degrees to the right.

In the second embodiment, it has been described that the bending portion 112 bends to the left when the pedal 528 rotates upward, and bends to the right when the pedal 528 rotates downward. However, the bending portion 112 may bend to the right when the pedal 528 rotates upward, and bend to the left when the pedal 528 rotates downward.

As described above, the first foot operation device 500a of the ultrasound diagnostic system 1 according to the second embodiment accepts an operation to change the angle at which the bending portion 112 is bent by stepping on the pedal 528, rather than by twisting the foot. In this case, the ultrasound diagnostic system 1 also accepts operations that were previously concentrated on the hands from the feet, thereby reducing the burden on manual operation. Therefore, the ultrasound diagnostic system 1 can improve the operability of the ultrasound probe 100.

Furthermore, it has been explained that the first foot operation device 500, 500a and the second foot operation device 600 according to the first embodiment, variant 1, variant 2, and second embodiment have a shape similar to footwear worn on the feet, such as shoes or slippers. However, the first foot operation device 500, 500a and the second foot operation device 600 are not limited to a shape similar to footwear, and may have other shapes. For example, the first foot operation device 500, 500a and the second foot operation device 600 may have a shape similar to a foot pedal.

At least one of the embodiments described above can improve the operability of the ultrasound probe 100.

These embodiments may be embodied in a variety of other forms, and various omissions, substitutions, modifications, and combinations of embodiments may be made without departing from the spirit of the invention.
