By the way, high safety is required for medical treatment devices such as medical chair units. For example, adjustments must be made so that operations using contact-type switches (non-voice operations) and voice operations do not interfere with or interfere with each other. Furthermore, it is desirable to realize not only safety but also ease of operation and operability (also referred to as usability).

The present disclosure describes a control device, a medical treatment system, and a control method that can achieve both safety and usability.

One aspect of the present disclosure is a control device that controls a controlled unit according to a user operation, the control device including control data for the controlled unit and data generated by a part of the user's body acting on the operating unit. an input section for inputting first operation data and second operation data related to the voice emitted by the user; a control unit that determines permission or prohibition of predetermined control, executes predetermined control, and makes permission or disapproval of the predetermined control different depending on whether the first operation data is input or the second operation data is input; Be prepared.

According to this control device, the control unit is configured to control the controlled unit based not only on the first operation data based on a part of the user's body acting on the operation unit, but also on the second operation data based on the voice emitted by the user. Executes predetermined control over. Therefore, operation by voice is possible, and ease of operation is realized. Since the control device can be operated by speech, it also contributes to the prevention of contact infection (infection control). Further, the control unit determines whether or not the predetermined control is permitted based on the control data. As a result, for example, if the control situation of the controlled part is not appropriate for performing the prescribed control, it is possible to perform control such as not performing the prescribed control (that is, prohibiting it), thereby increasing safety. . Moreover, the permission or disapproval of the predetermined control may be different depending on whether the first operation data is input, that is, the operation unit is operated, or when the second operation data is input, that is, the voice operation is performed. It's set. This makes it possible to prevent voice operations and controls from being accepted regarding predetermined control, thereby improving safety and operability. According to this control device, it is possible to achieve both safety and usability.

Note that in this specification, "a part of the user's body acts on the operation unit" refers to a part of the user's body coming into contact with the operation unit (physical contact), and a part of the user's body touching the operation unit (physical contact). This includes both cases in which the operation is performed without touching the operation part (i.e., without contact). The operation in which "a part of the user's body acts on the operation unit" includes contact operation and non-contact operation, and can be collectively referred to as "non-voice operation." Non-contact operations include, for example, infrared switches.

The medical treatment device is a medical and dental treatment device, and the controlled parts include the operation section of the seat on which the patient sits, the operation section of the backrest, the operation section of the dental instrument, the operation section of the operate, and the operation of the imaging device. The device may include at least one of the following: an operating section of a peripheral device such as a microscope, and an operating section of a gargle bowl. In this case, in the medical/dental medical treatment apparatus, voice operations are possible, and the above-mentioned permission/disapproval judgment can be made different depending on the operation of the operating section and the voice operation. It is possible to achieve both safety and usability in medical and dental treatment equipment.

The control unit determines whether the seat and backrest are in a first position where dental treatment is possible or a second position where dental treatment is not possible, based on the control data, and displays the first determination result. Accordingly, it may be determined whether or not the predetermined control is permitted. The condition (position) of the seat and backrest is an important element in dental treatment. Therefore, safety can be improved by determining whether or not the predetermined control is permitted depending on whether the position is the first position or the second position (first determination result).

The control unit may further determine the pickup status of the dental instrument based on the control data, and determine whether or not the predetermined control is permitted based on the second determination result. The pickup status of dental instruments is an important element in dental treatment. Therefore, the operability is further improved by determining whether or not to perform the predetermined control based on whether or not the dental instrument is being picked up.

The control unit may further determine the driving status of the dental instrument based on the control data, and determine whether or not to perform the predetermined control based on the third determination result. The driving status of dental instruments is an important element in dental treatment. Therefore, safety can be further improved by determining whether or not the predetermined control is permitted depending on whether or not the dental instrument is being driven.

Another aspect of the present disclosure is a control device that controls a controlled section according to a user operation, the control device being generated by control data of the controlled section and a part of the user's body acting on the operating section. an input section for inputting first operation data and second operation data related to the voice emitted by the user; and an input section for inputting first operation data and second operation data related to the voice emitted by the user; determine whether or not to permit the predetermined control to be performed, execute the predetermined control, and when the second operation data is input, make regulations regarding the permission or disapproval of the predetermined control stricter than when the first operation data is input. A control unit.

According to this control device, the control unit is configured to control the controlled unit based not only on the first operation data based on a part of the user's body acting on the operation unit, but also on the second operation data based on the voice emitted by the user. One predetermined control (out of a plurality of predetermined controls) is executed for the control. Therefore, voice operations are possible, and ease of operation is realized. Since the control device can be operated by speaking, it also contributes to improving infection control. Further, the control unit determines whether or not the predetermined control is permitted based on the control data. As a result, for example, if the control situation of the controlled part is not appropriate for performing the prescribed control, it is possible to perform control such as not performing the prescribed control (that is, prohibiting it), thereby increasing safety. . Moreover, when the second operation data is input, that is, when the operation is performed by voice, the plurality of predetermined controls are more effective than when the first operation data is input, that is, when the operation unit is operated. Regulations regarding permission will be tightened. Thereby, for example, it is possible to prevent voice operations and controls from being accepted for a relatively large number of predetermined controls, thereby improving safety and operability. According to this control device, it is possible to achieve both safety and usability.

When the second operation data is input and the control unit executes the predetermined control on the controlled unit, the control unit performs a confirmation process to confirm with the user whether or not to execute the predetermined control before executing the predetermined control. may be executed. The user may perform unintended voice operations. By executing the confirmation process, the possibility of unintended malfunctions can be reduced.

Before executing the confirmation process, the control unit determines, based on the control data, whether the seat and backrest in which the patient is seated are in a first position where dental treatment is possible or a second position where dental treatment is not possible. It may be determined whether the predetermined control is permitted or not based on the first determination result. The condition (position) of the seat and backrest is an important element in dental treatment. Therefore, safety can be improved by determining whether or not the predetermined control is permitted depending on whether the position is the first position or the second position (first determination result).

Yet another aspect of the present disclosure is a medical treatment system including a medical treatment device and a control device that controls a controlled section of the medical treatment device according to a user operation, wherein the control device includes control data for the controlled section; an input section for inputting first operation data generated by a part of the user's body acting on the operation section and second operation data related to the voice emitted by the user; Based on the operation data and the control data, it is determined whether or not a predetermined control to be performed on the controlled part is allowed, the predetermined control is executed, and the permission or disapproval of the predetermined control is determined based on the case where the first operation data is input. and a control unit that changes depending on when the second operation data is input.

Yet another aspect of the present disclosure is a control method for controlling a controlled section according to a user operation, which includes: (a) control data of the controlled section and a part of the user's body acting on the operating section; (b) an input step of inputting the first operation data generated by the user and second operation data related to the voice emitted by the user, and (b) based on the first operation data or the second operation data and the control data, It determines whether or not a predetermined control is to be performed on the controlled part, executes the predetermined control, and determines whether or not the predetermined control is allowed depending on whether the first operation data is inputted or the second operation data is inputted. and a control process for making the difference.

According to these medical treatment systems and control methods, it is possible to achieve both safety and usability, similar to the effects of the above-mentioned control device.

When a part of the user's body contacts the foot controller 4 and the operation section 11, the foot controller 4 and the operation section 11 generate an operation signal (first operation) indicating the operation content by physically touching these operation sections. data) and outputs it to an input/output port (input unit) 101 (see FIG. 3) of a control device M, which will be described later. The first operation data indicates the content of the non-voice operation. A non-voice operation is an operation in which at least a part of the user's body, such as a finger, hand, or foot, acts on the foot controller 4 or the operation unit 11 (such as a button or a non-contact sensor). In addition, in the medical and dental treatment system S, each of the above-mentioned control elements can also be changed via the control unit 31 of the management device 30 by the user making a predetermined input into the input device 33.

Note that the foot controller 4 and/or the operation section 11 may be configured to be able to communicate information wirelessly without being electrically connected to each control device or each control section, but even in such a case, At least part of the user's body, such as fingers, hands, feet, etc., contacts foot controller 4 or operation unit 11 .

The medical and dental treatment system S of this embodiment is configured to be able to change each of the above-mentioned control elements based on audio-related data input to the input/output port 101. The medical device 1 includes a control device M that performs a plurality of predetermined controls on each of the above-mentioned controlled units. The control device M includes a display control device 10, a medical instrument control device 9, a chair control section 13 of the chair 6, a basin control section 19 of the basin unit 7, and a lighting control section 21.

The auxiliary storage unit 104 includes, for example, a hard disk or a flash memory, and stores a larger amount of data than the main storage unit 103. The auxiliary storage unit 104 stores a program for causing at least one computer to function as the control device M. The processing in the control device M is realized, for example, by loading the program 110 into the main storage unit 103 and executing the program. The control unit 102 operates the input/output port 101 according to a program, and reads and writes data in the main storage unit 103 or the auxiliary storage unit 104. Data or databases required for processing may be stored in the main storage unit 103 or the auxiliary storage unit 104.

Note that in the medical and dental treatment system S, the management device 30 (see FIG. 2) may have the same configuration and functions as the control device M shown in FIG. 3. In that case, a management device 30 as a control device that controls each part of the medical device 1 is provided outside the medical device 1.

The input/output port 101 inputs control status data of the controlled unit, first operation data based on non-voice operations, and audio-related data based on voice operations. The input/output port 101 inputs audio-related data (second operation data) output from the audio input section 12. The voice-related data may be voice data generated based on the voice uttered by the user, or may be data converted into a predefined code based on the voice uttered by the user. That is, the audio-related data includes audio data and data converted into a code. The voice related data is generated based on the voice uttered by the user. The voice-related data is second operation data indicating the content of the operation by voice.

Each of the above-mentioned controlled units outputs a signal indicating the current value of each control element to the control unit corresponding to each controlled unit. For example, the seat 17 outputs a signal indicating the current height value to the chair control unit 13. The backrest 16 outputs a signal indicating the current value of the inclination angle of the backrest surface to the chair control unit 13. The input/output port 101 of the control device M inputs a signal indicating the current value of each control element as control status data (control data) indicating the control status of the controlled unit. In the medical and dental treatment system S of this embodiment, when the user performs a non-voice operation or a voice operation, predetermined control is executed according to the control status of the controlled unit shown in the control status data. If the control status of the controlled part satisfies a certain condition, the predetermined control is executed, but if the control status of the controlled part does not meet the certain condition or applies to another condition, the prescribed control is executed. , the predetermined control is not executed (prohibited).

The control unit 102 determines whether or not the predetermined control corresponding to the first operation data or voice-related data is permitted based on the first operation data or voice-related data and the control situation data. With reference to FIGS. 4 to 7, the determination of whether or not the predetermined control is permitted will be explained. In the following description, the control situation may be referred to as a "situation". FIG. 4(a) shows an example of a control situation regarding the chair 6, and FIG. 4(b) shows an example of a control situation regarding the dental instrument 25. 5(a) and 5(b), FIG. 6(a) and FIG. 6(b), FIG. 7(a) and FIG. 7(b), and FIG. 8(a) and FIG. 8(b). , similarly, the control situations of the chair 6 and the dental instrument 25 are illustrated, respectively.

For example, in the chair 6 shown in FIG. 4(a), the seat 17 is raised to a high position, and the backrest 16 is tilted to a substantially horizontal position. That is, in the chair 6, the seat 17 and the backrest 16 are in a medical treatment position (first position) where dental treatment can be performed. Further, in the dental instrument 25 shown in FIG. 4(b), the dental instrument 25 (for example, a handpiece) is removed from the instrument holder 15 (or instrument hanger), and the user's hand is removed. The end motor is driving the motor. That is, the dental instrument 25 is in operation. The second dental instrument 25B shown in FIG. 5(b) has been removed from the instrument holder 15 and picked up. Note that among the four types of dental instruments 25, only the second dental instrument 25B has been picked up, and the first dental instrument 25A, the third dental instrument 25C, and the fourth dental instrument 25B have been picked up. The instrument 25D is stored in the instrument holder 15. That is, at least one of the dental instruments 25 has been picked up (not in operation). In the dental instruments 25 shown in FIG. 6(b), all four types of dental instruments 25 are stored in the instrument holder 15 (not picked up). That is, all the dental instruments 25 are stored in the instrument holder 15. In the chair 6 shown in FIG. 7(a), the seat 17 is lowered and located in a low position, and the backrest 16 is located in a standing position. That is, in the chair 6, the seat 17 and the backrest 16 are in the exit position (second position) where dental treatment is not possible.

The control unit 102 determines whether or not to perform the predetermined control corresponding to the first operation data or the audio-related data, depending on these situations (control situations). Permission/denial of predetermined control means whether the control unit 102 is allowed to execute the predetermined control or not (prohibited). The control unit 102 (the medical instrument control device 9, the chair control unit 13, the basin control unit 19, the lighting control unit 21, etc.) determines the criteria for determining permission (or disapproval) when a non-voice operation is input, in accordance with a specific situation. A first rejection criterion) and a criterion for determining acceptance when a voice operation is input (second acceptance criterion) are separately stored. FIG. 4(c) illustrates a plurality of criteria for determining permission/disapproval of a plurality of predetermined controls corresponding to non-voice operations (first operation data) according to the situations shown in FIGS. 4(a) and (b). FIG. 4(b) shows a plurality of criteria for determining permission or disapproval of a plurality of predetermined controls corresponding to voice operations (second operation data) according to the situations shown in FIGS. 4(a) and (b). Illustrated. 5(c) and 5(d), FIG. 6(c) and FIG. 6(d), FIG. 7(c) and FIG. 7(d), and FIG. 8(c) and FIG. 8(d). , Similarly, criteria for determining whether to allow a plurality of predetermined controls corresponding to button operations (first operation data) and whether to permit or disallow a plurality of predetermined controls corresponding to voice operations (second operation data) according to each situation are similarly determined. The judgment criteria are illustrated respectively. In each figure of FIG. 4 to FIG. 7, the column represented in white means "executable". In addition, the column represented in gray means "impossible (prohibited)". In each figure, "HP" means handpiece (ie dental instrument 25). Handpieces include, for example, air turbine handpieces, motor handpieces, vacuum handpieces, and ultrasonic scaler handpieces. Each figure includes not only button operations but also operations using the foot controller 4, switches, infrared switches, and the like.

The control unit 102 stores these criteria. For example, when the chair 6 is in the medical treatment position and the dental instrument 25 is in operation, the medical instrument control device 9 determines whether it is possible to perform the operation (control) of "handpiece rotation". whether or not is stored for each of the non-voice operation and the voice operation. As shown in FIGS. 4C and 4D, for both non-voice operations and voice operations, the operation (control) of "handpiece rotation" is "impossible (prohibited)". The medical instrument control device 9 determines whether the operation (control) of "stopping the handpiece" is executable when the chair 6 is in the medical treatment position and the dental instrument 25 is in operation. is stored for each of non-voice operations and voice operations. As shown in FIGS. 4(c) and 4(d), the operation (control) of "stopping the handpiece" is "executable" for both non-voice operations and voice operations. Note that in this situation, all operations (controls) other than "stop the handpiece" are "impossible (prohibited)" for both non-voice operations and voice operations. The situations shown in FIGS. 4(a) and 4(b) are the second medical treatment status, and the medical treatment status is estimated to be "under medical treatment." In this case, for example, the required level of security is "high" and the required level of usability is "low." In the second medical treatment situation, non-voice operations and voice operations for almost all controlled units are prohibited (restricted).

For example, when the chair 6 is located in the medical treatment position and at least one of the dental instruments 25 is being picked up (not in operation), the basin control unit 19 controls the "vacuum line cleaning" function. Whether or not the operation (control) is executable is stored for each non-voice operation and voice operation. As shown in FIGS. 5(c) and 5(d), regarding non-voice operations, the operation (control) with “vacuum pipe cleaning” is “executable”, while regarding voice operations, Operation (control) with "vacuum pipe cleaning" is considered "impossible (prohibited)". In this way, the basin control unit 19 allows or disables the predetermined control depending on whether the first operation data is input or the second operation data is input. From another point of view, when looking at the entire plurality of predetermined controls shown in FIGS. 5(c) and 5(d), when the second operation data is input, the control unit 102 Regulations regarding permission or disapproval of a plurality of predetermined controls are stricter than in the case of input. As shown in FIG. 5(c), all predetermined controls are "executable" for non-voice operations, while as shown in FIG. 5(d), there are five types of voice operations. The predetermined control is "unexecutable (prohibited)". In other words, the number of predetermined controls that are "impossible (prohibited)" when the second operation data is input is the same as the number of predetermined controls that are "impossible (prohibited)" when the first operation data is input. the number of predetermined controls. The situations shown in FIGS. 5(a) and 5(b) are the first medical treatment situation, and the medical treatment situation is estimated to be "medical treatment start." In this case, for example, the required level of security is "medium" and the required level of usability is "medium." In the first medical treatment situation, voice operations for maintenance-related controlled units are prohibited (restricted). The voice operation for the maintenance system is a voice operation related to the maintenance of the conduit installed inside the chair 6, the spittoon, and the like. Examples include voice operations that can give commands to clean vacuum pipes, clean water supply pipes, drain residual water from pipes, and the like.

FIGS. 6(c) and 6(d) show an example of permission/disapproval determination when the chair 6 is in the medical treatment position and all the dental instruments 25 are stored. The situation shown in FIGS. 6(a) and 6(b) is the third medical treatment situation, and the medical treatment situation is estimated to be "medical treatment completed." In this case, for example, the required level of security is "medium" and the required level of usability is "medium." In the third medical treatment situation, voice operations for controlled parts of the handpiece system and maintenance system are prohibited (restricted).

FIGS. 7(c) and 7(d) show examples of permission/disapproval determination when the chair 6 is in the exit position and all the dental instruments 25 are stored. The situations shown in FIGS. 7A and 7B are the fourth medical treatment status, and the medical treatment status is estimated to be "under treatment" or "on standby." In this case, for example, the required level of security is "small" and the required level of usability is "high." In the fourth medical treatment situation, voice operations for the controlled parts of the handpiece system and camera system are prohibited (restricted).

FIGS. 8(c) and 8(d) show examples of permission/disapproval determination when the chair 6 is in the exit position and the dental instrument 25 is in operation. The situation shown in FIGS. 8(a) and 8(b) is the fifth medical treatment status, and the medical treatment status is estimated to be "under maintenance." In this case, for example, the required level of security is "small" and the required level of usability is "high." In the fifth medical treatment situation, voice operations for the controlled parts of the chair system, handpiece system, and camera system are prohibited (restricted).

The control unit 102 determines whether the predetermined control corresponding to the first operation data or the audio-related data is permitted, and executes the predetermined control only when it is determined that the predetermined control is executable. The control unit 102 determines whether or not the predetermined control corresponding to the first operation data or the audio-related data is permitted, and if it is determined that the predetermined control is not executable (prohibited), it does not execute the predetermined control.

Next, the processing (control method) performed by the control device M will be described with reference to FIG. 9 and FIGS. 4 to 7. First, the input/output port 101 of the control device M inputs control status data (step S01, (a) input step). In step S01, for example, control status data regarding the chair 6 and the dental instrument 25 is input. The control unit 102 of the control device M can always input the first operation data and audio-related data input to the input/output port 101. Next, the control unit 102 determines whether the first operation data or audio-related data has been input (step S02). If it is determined that the first operation data or audio-related data has not been input (step S02; NO), the control unit 102 repeats the process of step S01. If it is determined that either the first operation data or the voice-related data has been input (step S02; YES), the control unit 102 determines the control status of the chair 6 and the dental instrument 25 input in step S01. (Step S03). For example, the control unit 102 determines whether the chair 6 is located in the medical treatment position or the exit position, and outputs the determination result (first determination result). Further, the control unit 102 determines the pickup status of the dental instrument 25 and outputs the determination result (second determination result). Further, the control unit 102 determines the operating status (driving status) of the dental instrument 25, and outputs the determination result (third determination result). Based on these first, second, and third determinations, the control unit 102 determines which medical treatment situation the current medical treatment situation is (for example, which of the first to fifth medical treatment conditions described above). do.

The control unit 102 determines which of the first operation data and the audio-related first operation data has been input, according to the determination result in step S02 (step S04). When the first operation data is input, the control unit 102 determines whether or not the non-voice operation shown in FIGS. 4(c), 5(c), 6(c), and 7(c) is permitted. Permission or rejection is determined based on the criteria (first rejection criteria) (step S05). The control unit 102 controls the controlled unit only when the determination result is “executable” (step S06, (b) control step).

On the other hand, when voice-related data is input, the control unit 102 determines whether or not the voice operation is permitted as shown in FIGS. 4(d), 5(d), 6(d), and 7(d). Permission or rejection is determined based on the criteria (second rejection criteria) (step S07). The control unit 102 controls the controlled unit only when the determination result is “executable” (step S06). In that case, step S08 and step S09 shown in FIG. 9 may be omitted.

The judgment in step S05 and the judgment in step S07 are based on different judgment criteria, and the permission or disapproval of some predetermined controls is different. Through the series of processes described above, whether or not non-voice operations and voice operations can be accepted is made different depending on the situation. By disabling (prohibiting) voice commands that do not suit the situation, the possibility of misrecognition is reduced. Note that in the control device M, being infeasible (prohibited) may mean the same as excluding from speech recognition targets.

Prohibition (restriction) of voice commands is set based on required safety and usability needs. For example, in the second medical treatment situation (see FIG. 4), the medical treatment situation estimated based on the state of the medical treatment device 1 is that medical treatment is in progress, so there is a great need to ensure safety. For this reason, voice recognition is performed based on terms used in conversation rather than commands, and almost all controls are restricted to prevent unintentional control by the user (voice misrecognition control).

In the first medical treatment situation (see FIG. 5), the medical treatment situation estimated based on the state of the medical treatment device 1 is the start of medical treatment, so there is not a great need for ensuring safety. For this reason, a relatively high priority is given to improving usability, and control using many voice commands is made possible. Note that since the handpiece has been removed from the instrument holder 15 and the user has an intention to use it, on the other hand, there is no intention to activate the maintenance system, so it is necessary to prevent voice misrecognition control. Therefore, control of the maintenance system by voice commands is limited.

In the third medical treatment situation (see FIG. 6), the medical treatment situation estimated based on the state of the medical treatment device 1 is the end of the medical treatment, so there is not a great need for ensuring safety. For this reason, a relatively high priority is given to improving usability, and control using many voice commands is made possible. Note that since the handpiece is stored in the instrument holder 15 and the user has no intention of using it, it is necessary to prevent voice misrecognition control. Therefore, control of the handpiece by voice commands is limited.

In the fourth medical treatment situation (see FIG. 7), the medical treatment condition estimated based on the state of the medical treatment device 1 is completion of treatment or standby, so there is little need for ensuring safety. For this reason, priority is given to improving usability, and control using many voice commands is enabled. Note that since the handpiece is stored in the instrument holder 15 and the user has no intention of using the handpiece, it is necessary to prevent voice misrecognition control. Therefore, control of the handpiece by voice commands is limited.

In the fifth medical treatment situation (see FIG. 8), since the medical treatment device 1 is in preparation for maintenance or in a state estimated based on the condition of the medical device 1, there is little need for ensuring safety. For this reason, priority is given to improving usability, and maintenance system control is enabled by voice commands. Note that it is necessary to prevent voice misrecognition control due to maintenance preparation or status, and control by voice commands of the chair system, handpiece system, and camera system is restricted.

Note that safety and usability, which are the objectives of the control according to this embodiment, may not be clearly distinguishable, and both may be achieved. Furthermore, the estimated clinical situation may differ from the actual medical situation, and non-voice operations are possible even in situations where voice recognition control cannot be used. For example, in the first medical treatment situation, that is, in the chair treatment position, when the handpiece is removed from the instrument holder 15, and when the handpiece is stopped, the start of medical treatment is estimated, and maintenance-related voice recognition control is restricted. On the other hand, although it may be rare, some users may want to operate the maintenance system in that state. Allows non-voice operation.

Next, the processing when step S08 and step S09 shown in FIG. 9 are executed will be described. Following the process in step S07, the control unit 102 executes a confirmation process to confirm whether or not to execute predetermined control (step S08). For example, as shown in FIG. 10(a), the chair 6 is located in the medical treatment position, and as shown in FIG. 10(b), at least one of the dental instruments 25 is picked up ( When an operation to change the chair 6 to the exit position or the gargling position is input in a situation where the chair 6 is not in operation (not in operation), a confirmation process is executed (in FIG. 10(c), the operation name is in parentheses. ing).

In the confirmation process of step S08, for example, the display control device 10 controls the display device 3 to display a confirmation message to the user asking, "Do you really want to perform the operation of XX?" Alternatively, the control unit 102 may control a speaker (not shown) or the like (notification unit) to make a "beep" sound twice (or multiple times) or to display a message saying "Do you really want to perform the operation in 〇○○? ?” a voice message is played. In this way, when the second operation data is input and the control unit 102 executes the predetermined control on the controlled unit (that is, it is executable under the current situation), the control unit 102 performs the predetermined control in step S06. Before executing the control, it is confirmed whether the prescribed control is really executed. In this way, for voice operations that are unlikely to be instructed in a specific situation, a process may be inserted to confirm whether or not to perform them, just in case.

The user presses "OK" displayed on the touch panel display of the display device 3. Alternatively, the user utters a voice such as "yes", "OK", or "you may execute" to the voice input unit 12. When the control unit 102 confirms that the predetermined control can be executed as a result of the confirmation process (step S08; YES), it controls the controlled unit (step S06). As a result of the confirmation process, if the control unit 102 does not confirm that the predetermined control may be executed, or if it confirms that the predetermined control should not be executed (step S08; NO), the control unit 102 controls the controlled unit. Finish a series of processes without controlling.

According to the control device M, the medical and dental treatment system S, and the control method, the control unit 102 not only generates first operation data generated by a part of the user's body acting on the operation unit, but also generates sound generated by the user's voice. Also based on the related data, predetermined control is performed on the controlled unit. Therefore, operation by voice is possible, and ease of operation is realized. Since the control device M can be operated by speech, it also contributes to the prevention of contact infection. Further, the control unit 102 determines whether or not the predetermined control is permitted based on the control situation data. As a result, for example, if the control situation of the controlled part is not appropriate for performing the prescribed control, it is possible to perform control such as not performing the prescribed control (that is, prohibiting it), thereby increasing safety. . Furthermore, whether or not the predetermined control is permitted is made different depending on whether the first operation data is input, that is, a non-voice operation is performed, or when voice-related data is input, that is, a voice operation is performed. There is. This makes it possible to prevent voice operations and controls from being accepted regarding predetermined control, thereby improving safety and operability. According to this control device M, it is possible to achieve both safety and usability.

When voice-related data is input, that is, when a voice operation is performed, regulations regarding permission or disapproval of multiple predetermined controls are stricter than when first operation data is input, that is, when a non-voice operation is performed. be done. Thereby, for example, it is possible to prevent voice operations and controls from being accepted for a relatively large number of predetermined controls, thereby improving safety and operability. According to this control device, it is possible to achieve both safety and usability.

In this embodiment, in a system equipped with a voice control function and a non-voice switch control function, the operation of the two does not become a barrier to each other, but rather takes advantage of the characteristics of each to improve accessibility and convenience of function control. is improving. In recent years, as speech recognition technology has developed and it has become possible to accurately convert speech into data, speech recognition technology has come to be used in a wide range of fields. Voice recognition and control technology that applies it are being installed in a variety of devices. The medical field is no exception, and technology is progressing to improve the operability and sanitary usability of medical devices by adding voice recognition and voice control functions.

Using voice for control eliminates the need for complex mechanical operations (simplifies operation), enables non-contact control (achieves high infection control), and improves operator movement. Benefits include eliminating the need for changes in posture (enabling operations while maintaining posture), etc. On the other hand, because medical equipment directly deals with the bodies of people and animals, it is essential that they have an extremely high level of safety. To this end, various designs have been studied to prevent malfunctions of medical devices and designs that can prevent erroneous operations by users.

In the case of a medical treatment device equipped with voice control technology such as this embodiment, there are two types of control: control using contact switches (membrane switches, button-like switches, foot controller switches, etc.) and non-contact operation. The main premise is that adjustments are made so that controls (voice operations, operat distance measurement sensors, etc.) do not interfere with or interfere with each other. In addition to this, in this embodiment, rather than simply replacing the configuration in which things that can be done with non-voice operations can also be done with voice operations, the present embodiment also allows for non-voice operations and voice operations to be performed separately depending on the clinical situation (scene). Efforts have been made to achieve higher usability and safety based on the advantages/weaknesses of operation.

For this purpose, the following two elements are being focused on.
1) “Depending on the medical situation (scene)”
From before the start to the end of the medical treatment, we will discuss operating methods that should not be selected (or should be recommended) considering the acoustic environment of the medical treatment space and the medical situation (scene), as well as precautions to be taken during specific medical procedures. Rules for operations that must be (or prohibited) performed are assumed.
2) Characteristics and strengths/weaknesses of each operation method (non-voice operation/voice operation) when sending control signals to medical equipment

Regarding 1), depending on the ongoing medical situation (scene), "the medical device" regulates the operation of the medical device that requires caution and prohibitions unique to medical and dental care, making it possible to improve voice recognition. It is possible to avoid errors in medical equipment under such environments. For example, control by voice recognition is turned off when the patient is not seated. Chair automatic operation by voice cannot be accepted while the handpiece is being picked up. For example, when device A is ON, device B can only be operated by non-voice operations.In the dental chair unit, whether or not to accept non-voice operations and voice operations may differ depending on the clinical situation (scene). With this configuration, it is possible to greatly improve the operability and safety of controlling the medical device using the voice recognition function.

Regarding 2), for example, non-voice operations require the user to learn how to operate, but the control signals are input while reliably reflecting the user's intentions (purpose of operation), so there are fewer erroneous operations. It has characteristics. Therefore, it is preferable to reduce the number of items subject to control (relax regulations) and ensure operable functions. On the other hand, with voice operations, the user can easily issue instructions (although the user needs to learn keywords that serve as commands) and does not require any physical changes during operation. However, depending on the acoustic environment, noise may be generated, and it is assumed that voice recognition will not work properly or that erroneous operations may occur due to picking up other voices. Therefore, it is preferable to increase the number of items subject to control (stricter regulation) and to limit the operable functions. In addition, for example, when performing voice recognition, the device repeats what has been heard (listening function), and the commands that can be accepted are filtered according to the noise level of the acoustic environment (reception items according to the acoustic environment conditions). It will be possible to pursue even greater safety by strengthening the control regulations unique to voice recognition, such as by adding configurations such as a screening function for voice recognition. In addition, while ensuring safety, usability is improved by allowing the device to perform prohibited operations in a specific clinical situation (scene) by confirming with the operator in advance (exception operation function). It is also possible to improve In this way, both usability and safety are improved by the configuration in which the content of control (restricted object) is switched depending on the selection of non-voice operation, voice operation, and operation method.

In this embodiment, the control device uses the operating methods according to the medical treatment situation (scene) by combining the above-mentioned elements 1) and 2). Voice control commands that can be issued are regulated (limited) depending on the clinical situation (scene). Then, controllable objects are regulated (limited) for voice operations and non-voice operations, and for each operation.

According to this embodiment, the following effects are achieved.
(i) Traditionally expected effects such as improved infection control, improved usability, and improved safety. (ii) Realization of high accessibility. Smooth and stable equipment operation is possible no matter who operates it and for what purpose.
(iii) Achieving reliable operation through programmatic assistance Since the control program regulates the control target for each operation (automatically prohibits specific items), even voice control, which inevitably leaves some uncertainty, can be performed without triggering. Reliable voice control can be achieved by setting detailed conditions. Depending on the content of the command, it is also possible to input commands to multiple devices without having to be close to each control target.

Further, in the above embodiment, the medical treatment device 1 is a medical and dental treatment device, and the controlled parts include the movement part of the seat 17 on which the patient is seated, the movement part of the backrest 16, and the movement of the dental instrument 25. , an operating section of the lighting device 8 (operate), and an operating section of the basin unit 7 (gargle bowl). In the medical/dental medical treatment apparatus 1, voice operations are possible, and the above-mentioned permission/disapproval judgment can be made different between non-voice operations such as touching the operating section and voice operations. It is possible to achieve both safety and usability in the medical/dental medical treatment device 1.

The control unit 102 determines whether the seat seat 17 and the backrest 16 are in a first position where dental treatment is possible or a second position where dental treatment is not possible, based on the control status data, and Based on the first determination result, it is determined whether or not the predetermined control is permitted. The conditions (positions) of the seat seat 17 and the backrest 16 are important factors in dental treatment. Therefore, safety is enhanced by determining whether or not to perform the predetermined control depending on whether the position is the first position or the second position (first determination result).

The control unit 102 further determines the pickup status of the dental instrument 25 based on the control status data, and determines whether or not the predetermined control is permitted based on the second determination result. The pickup situation of the dental instrument 25 is an important element in dental treatment. For example, the pickup status of the dental instrument 25 indicates whether the user has a clear intention to operate the dental instrument 25. Therefore, the operability is further improved by determining whether or not the predetermined control is permitted depending on whether or not the dental instrument 25 is picked up.

The control unit 102 may further determine the driving status of the dental instrument 25 based on the control status data, and determine whether or not to perform the predetermined control based on the third determination result. The driving situation of the dental instrument 25 is an important element in dental treatment. For example, while the dental instrument 25 is being driven, there is a high possibility that the patient is being treated using a handpiece or the like, so caution is required. As shown in FIGS. 4(c) and 4(d), only stopping the handpiece is valid for both non-voice and voice operations, and no other operations are accepted. In this way, safety and operability are improved by determining whether or not to perform predetermined control based on whether or not the dental instrument is being driven.

When the control unit 102 executes predetermined control on the controlled unit when audio-related data is input, the control unit 102 performs a confirmation process to confirm with the user whether or not to execute the predetermined control before executing the predetermined control. Execute. The user may perform unintended voice operations. By executing the confirmation process, the risk of unintended malfunctions can be reduced.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, as shown in FIG. 11(a), if noise or a voice operation that does not suit the situation continues, the control device M switches to a mode in which voice recognition is not performed, as shown in FIG. 11(b). It's okay. In that case, a sound may be emitted from a speaker or the like, followed by a false recognition detection sound of "beep", followed by a continuous sound of "beep", and the voice recognition may be stopped. A microphone off mark may be lit on the screen of the display device 3. The user hears or sees this and performs an operation using the foot controller 4 or the operation unit 11.

As shown in FIG. 12(a), when all the dental instruments 25 are stored without picking up the dental instrument 25, the control device M stops voice recognition. It is also possible to shift to the specified mode. If any one dental instrument 25 is picked up (see FIG. 12(b)) and the user's clear intention to operate is confirmed, the mode may be returned to voice recognition (see FIG. 12(c)). reference). In that case, for example, the screen display of the display device 3 may be switched from a microphone off mark to a microphone on mark.

The control unit 102 may determine whether or not to perform the predetermined control based on the control status of controlled units other than the chair 6 and the dental instrument 25, such as the basin unit 7 and the lighting device 8.

One or more dental instruments 25 may be stored on the tray table 5.

The medical and dental treatment system S and the medical treatment device 1 may be used for otorhinolaryngology, obstetrics and gynecology, or urology. The medical treatment system may be a system other than the medical and dental treatment system S. The control device and control method of the present disclosure may be applied to a medical treatment system equipped with a bed-type medical treatment table. Note that when a bed-type treatment table is used, the "medical treatment position" is basically an elevated position. The "exit position" is basically the lowest position (not ascending or descending).
