Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ultrasonic probe for diagnosing the body using ultrasonic waves.

2. Description of the Related Art Structures of Conventional Examples and Their Problems Currently, with the spread of ultrasonic diagnostic devices, ultrasonic probes are being used for various medical diagnoses. In particular, surgical ultrasound probes used during surgery play an indispensable and important role in medical diagnosis. For example, when an incision is made in the subject's body during surgery and a surgical ultrasound probe is brought into direct contact with the organ, the organ in contact can be seen on the ultrasound diagnostic equipment display connected to the surgical ultrasound probe. By displaying the tomographic image in real time on the screen, the operator can confirm the affected area within the body by observing the image.

Now, when using a surgical ultrasound probe during surgery, as shown in FIG.
When inserting a surgical ultrasonic probe into a subject's body, there is a risk of damaging internal organs.
Therefore, this places a heavy burden on the operator who performs the diagnosis. Furthermore, when manufacturing ultrasonic probes for surgery, the fluid hardening agent is injected from the opening connected to the sleeve 3 at the tip of the gripping part 2, as shown in Figure 2, but since the opening is narrow, The cable 4 makes it difficult to inject the fluid hardening agent, making it impossible to completely seal the fluid hardening agent inside the support 1 and the grip portion 2. That is, especially when performing diagnosis using a surgical ultrasonic probe, its airtightness and waterproofness are problematic.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention provides an ultrasonic probe that can be inserted without any trouble without placing a burden on the operator who diagnoses the organs of a subject who has made an incision, and that has improved sealing and waterproof properties. It is something that provides children.

Structure of the Invention The present invention achieves the above object by forming a support member of an ultrasonic probe into a substantially cylindrical shape, and providing a recessed portion on the upper surface of the support member to serve as an injection portion for a fluid hardening agent.

DESCRIPTION OF EMBODIMENTS FIG. 3 shows a cross-sectional view of an ultrasonic probe according to an embodiment of the present invention, and FIG. 4 shows a perspective view thereof.

In FIGS. 3 and 4, a group of ultrasonic transducer elements 6 is arranged on a support 5, and an acoustic lens 7, which serves as a subject contact surface, is provided on the lower surface of the ultrasonic transducer group 6. ing. On the other hand, a back loading material 8 is provided on the upper surface of the ultrasonic transducer element group 6 to attenuate the propagation of sound waves to the upper surface.

The ultrasonic transducer section is composed of the above-mentioned ultrasonic transducer element group 6, acoustic lens 7, and back loading material 8. The support 5 has a substantially cylindrical shape as shown in FIG. 4, and has two cylindrical recesses 9 on the upper surface of the support 5. From the recesses 9, as shown in FIG. 14 is injected and the cap 11 is used to completely seal the inside of the support 5 and the gripping part 10.

The ultrasonic transducer group 6 is connected to a cable 12, which passes through a substantially cylindrical grip portion 10 and a sleeve 13 in the longitudinal center of the support 5, and is connected to an ultrasonic diagnostic device display (not shown). ) will be displayed. Further, the opening end of the gripping portion 10 has a concave recess, and is connected to the sleeve 13 having a convex recess through a threaded fit.

According to the above configuration, by making the support body 5 and the gripping part 10 substantially cylindrical, the entire ultrasound probe becomes cylindrical, and ultrasonic waves can be transmitted without damaging the incised organs of the subject. A probe can be inserted.

In addition, by providing two recesses 9 on the upper surface of the support 5, the fluid hardening agent 14 can be injected, and the support 5
And complete sealing by the gripping part 10 is possible.

Effects of the Invention As described above, the present invention has a support having a substantially cylindrical shape, so that it can be inserted without causing any damage to the incised organ of the subject, and it can be inserted without causing any burden or trouble to the operator. Diagnosis can be made. In addition, by providing an injection part on the top surface of the support, the flow hardening agent can be injected from the injection part, and the support is completely sealed, solving the problem of waterproofness and sealability, and highly reliable ultrasonic waves. It becomes possible to provide a probe.
