The probe (vibration transmission member) in this type of ultrasonic treatment device is generally made of a metal member, and its tip serves as a working end. Further, the probe (vibration transmission member) has a structure in which an ultrasonic vibrator (ultrasonic vibration generating section) is connected to the base via a horn. The ultrasonic vibrator generates ultrasonic waves with a driving frequency that sets the tip of the probe at the antinode of the vibration, thereby generating an amplitude necessary for treatment at the tip of the probe.

付けている。FIG. 5 shows a schematic configuration of a conventional general ultrasonic treatment device having a flat tool member at the tip of the probe. That is, a piezoelectric element (ultrasonic vibration generating section) 3 is sandwiched between a horn 1 which also serves as a front plate and a backing plate 2, and the piezoelectric element 3 is tightened with bolts 4 and nuts 5.

A tool 8 shaped like a flat plate is integrally provided.

織の切除、破砕を行なうものである。When an electric signal from an ultrasonic drive signal oscillator (not shown) is applied to the piezoelectric element 3 manually, the piezoelectric element 1 performs mechanical ultrasonic vibration based on the drive signal. After the amplitude of this ultrasonic vibration is expanded by the horn 1, it is transmitted to the probe 6, and the amplitude is further expanded by the second horn 7 in the probe 6. Thereafter, the ultrasonic vibrations are transmitted to a flat tool 8 at the tip of the probe 6 that performs the work, and the living tissues such as bones and cartilage that are in contact with this flat tool 8 are resected and crushed. be.

超音波治療装置では、比較的外径の大きなホーン７が、
工具部材の根元付近に存在しているため、狭い空間を通
って体腔内の処置を施すことは難しく、操作性が悪い。Also, a flat tool 8 at the tip of the vibration transmission member
As shown in Fig. 6a, the horn (vibration transmitting member) and the tool are integrated. In the ultrasonic treatment device of the type disclosed in Japanese Patent No. 53-19874, the horn 7 having a relatively large outer diameter has a
Since it is located near the base of the tool member, it is difficult to perform treatment inside the body cavity through a narrow space, and operability is poor.

になるという問題もあった。In addition, since the horn 7 or vibration transmission member with a circular cross section suddenly changes to a rectangular cross section from the vibration transmitting member to the tool 8, stress concentration tends to occur near the root of the tool 8, and when high amplitude ultrasonic vibrations propagate, , this part is easy to break,
There is a risk that the tip of the tool 8 may fall into the body cavity. Furthermore, since the horn 7 with a circular cross section and the tool 8 with a rectangular cross section are integrally formed, there is a problem that manufacturing is time consuming and costly.

波振動を伝播させた場合、着脱する構造部分が破損した
り、工具部分が脱落し易いという問題点がある。Further, the conventional ultrasonic treatment apparatus having a flat tool 8 at the tip of the probe 6 has the following problems. In other words, when the tool 8 is configured to be detachable from the vibration transmission member of the probe 6, the mechanical strength of the attachment/detachment structure is lower than that of a structure in which the vibration transmission member and tool member are integrated. tends to decline. For this reason, when high-amplitude ultrasonic vibrations are propagated, there are problems in that the structural parts to be attached and detached may be damaged, and the tool parts may easily fall off.
さらに、複雑な着脱構造をとるために、その制作に手間
がかかり、製造コストが嵩むという問題がある。Furthermore, since it has a complicated attachment/detachment structure, there is a problem in that it takes time and effort to produce, and the manufacturing cost increases.
本発明は上記課題に着目してなされたもので、その目的
とするところは、狭い空間を通して、体腔深部へ到達で
きるとともに、比較的高振幅の超音波発振が可能な平板
状の工具を持つ超音波治療装置を提供することにある。The present invention has been made in view of the above-mentioned problems, and its purpose is to provide an ultrasonic device with a flat tool capable of reaching deep body cavities through narrow spaces and capable of emitting relatively high amplitude ultrasonic waves. The purpose of the present invention is to provide a sound wave therapy device.

するとき略λ／２の整数倍としたものである。[Means and effects for solving the problems] In order to solve the above problems, the ultrasonic treatment device of the present invention has the following features:
Vibration transmission that includes an ultrasonic vibration generating section, a horn that magnifies the amplitude of the ultrasonic vibration from the ultrasonic vibration generating section, and a flat tool section that is connected to the tip of the horn and has a working section at the tip. The vibration transmitting member has a substantially flat plate shape over its entire length including the tool portion, and the length in the transmission direction of the ultrasonic vibration is approximately λ/2, where λ is the wavelength of the ultrasonic vibration. It is an integer multiple.

超音波発振を行うことが可能である。Therefore, since the vibration transmission member is formed of a plate integrally with the flat tool and has a length corresponding to an integral multiple of half the wavelength of the ultrasonic vibration, it is possible to penetrate deep inside the body cavity through a narrow space. It is possible to easily perform this treatment. Furthermore, the vibration transmission member is a member that is simply formed by processing the tip of a strip-shaped plate into a tool shape, and is easy to process, so that manufacturing costs can be reduced. Furthermore, since the connecting portion between the vibration transmitting member and the flat tool does not have a complicated shape, the strength is uniform throughout the entire length of the vibration transmitting member, and it is possible to perform ultrasonic oscillation with higher amplitude.
