して利用している。[Prior Art] A conventionally known ultrasonic treatment device of this type is constructed by connecting an ultrasonic vibration generating unit equipped with an ultrasonic transducer with a probe for transmitting ultrasonic vibrations. . The probe for transmitting ultrasonic vibrations is formed of a hollow vibrator, and its inner hole is used as a suction path for the water supply liquid. Further, the periphery of the probe, except for the distal end for treatment, is covered with a sheath, and the space between the probe and the sheath is used as a water supply channel.

ようになっている。During treatment, this type of ultrasonic treatment device cools the heated probe by sending water into the body cavity through the water supply channel, and also cuts and emulsifies the water supply liquid once it has flowed into the body cavity using ultrasonic vibrations. It is designed to be sucked out to the outside through the suction channel along with the crushed tissue or crushed stone fragments.

の妨げとなる。However, when the ultrasonic vibration generator of an ultrasonic treatment device is driven at high output and the ultrasonic vibrations are transmitted to the probe, the probe generates more heat than usual, which requires a large amount of water to be supplied. Treatment is hindered because a large amount of water fluid accumulates in the body cavity, and water splashes occur, impairing the visual field.

A method such as that described in No. 493694 has been proposed. That is, in Japanese Patent Application No. 1-289652, the system that covers the probe is constructed in two layers, and one of the gaps between the probe and the inner sheath part and the gap between the inner sheath part and the outer sheath part is filled with a water supply channel, and the other one is filled with a water supply channel. The gap is used as a second suction path, and a communication path is formed at the distal end portion of the inner sheath portion before the distal end of the outer sheath portion to communicate the water supply channel and the second suction path. Further, in US Pat. No. 4,493,694, a small hole communicating with a suction path inside the probe is provided near the tip of the probe to collect the water supply liquid.

Most of the water supplied in this way is sent into the body cavity, but a part of it does not flow out from the distal end of the outer sheath portion 22b and flows through the communication path 27 inside the distal end portion.
The liquid is sucked directly into the second suction path 26 through the suction passage 26 .

The water supply liquid sucked directly into the second suction path 26 joins the first suction tube 16 through the second suction tube 32 and is sent to the suction pump 30 side. At this time, since a valve 31 is provided in the second suction path 26, when the valve 31 is opened, the water supply liquid sent from the water supply tube 29 to the water supply channel 25 is transferred to the second suction path near the tip. Suction path 2
There are two types of water: one that is collected at 6, and the other that is directly sent to the surgical site. Then, the collected water supply liquid passes through the second suction tube 32 and joins the first suction tube 16.

In other words, when the temperature of the tip is below a certain temperature,
The on-off valve is fully open, and the water supply liquid passes through the water supply channel 25 on the outer periphery of the probe 20 and is divided into one that is recovered from the second suction channel 26 and one that is sent to the tip. However, when the temperature of the surgical area exceeds a certain temperature, this temperature is detected by the temperature detection sensor 35 and the temperature detector 33.
A signal is transmitted to the valve opening/closing control equipment RL134 to close the opening/closing valve. When the on-off valve is closed, the water supply liquid is not collected and all water is supplied from the tip of the sheath 22.

３は第２の吸引ポンプ４０に接続されている。In this third embodiment, a second suction pump 40 is connected to the second suction path 32. Further, a temperature detection sensor 35 is installed at the distal end of the outer sheath 22b, and this temperature detection sensor 35 is connected to the temperature detector 33 via an on/off switch 41. And this temperature sensor 3
3 is connected to a second suction pump 40.

には小穴３６に対応する突起３７が設けられている。4 to 6 show a fourth embodiment. In this fourth embodiment, a small hole 36 communicating with the suction path 15 provided inside the probe 20 is provided at the distal end of the probe 20 covered with a heavy sheath 38, and a small hole 36 is provided inside the sheath 38. A corresponding protrusion 37 is provided.

３６を通って回収されなくなる。The water supply liquid advances through the gap between the probe 20 and the sheath 38 as shown on the left side of FIG.
When the sheath 38 is rotated as shown by the arrow in FIGS. 4 and 5, the protrusion 37 closes the small hole 36 as shown on the right side of FIG. 36 and is no longer collected.

従って、術者がシースを回転させることにより、プロー
ブの冷却効率を下げることなく先端送水量を変化させる
ことができるので、安全な治療を行なうことができる。Therefore, by rotating the sheath, the operator can change the amount of water delivered to the tip without reducing the cooling efficiency of the probe, allowing safe treatment.

第７図は、本発明の第５の実施例を示している。FIG. 7 shows a fifth embodiment of the invention.

この第５実施例では、第１実施例と同様にプローブを覆

A balloon 39 is provided on the outer periphery of the balloon. By inflating this balloon 39, the second suction path 26 is closed.

従って、図示しないハンドスイッチまたはフットスイッ

回収される送水液を全て先端に送水することができる。Therefore, by inflating the balloon using a hand switch or a foot switch (not shown), all of the water liquid collected from the second suction path 26 can be sent to the tip.

この実施例でもプローブの冷却効率を下げることなく先
端送水量を変化させることができるので、安全な治療を
行なうことができる。Also in this embodiment, the tip water supply amount can be changed without lowering the cooling efficiency of the probe, so safe treatment can be performed.

次に、第８図から第１０図を参照しながら超音波振動子
における電極の変形例について説明する。Next, modifications of the electrodes in the ultrasonic transducer will be described with reference to FIGS. 8 to 10.

第８図および第９図は第１の変形例を示している。この
第１変形例では、振動子４における電極６の電極本体５
０と、コード接続部５２との間に切欠５４が形成されて
いる。従って、振動子４を組立てる際にコード接続部５
２を容易に曲げることができるので、作業効率を向上さ
せることができる。FIGS. 8 and 9 show a first modification. In this first modification, the electrode body 5 of the electrode 6 in the vibrator 4
A notch 54 is formed between the cord connecting portion 52 and the cord connecting portion 52 . Therefore, when assembling the vibrator 4, the cord connecting portion 5
2 can be easily bent, improving work efficiency.

また、上記電極６はさらに電極本体５０の外径が圧電素
子４の外径よりも小さく形成されている。In addition, the electrode 6 is further formed so that the outer diameter of the electrode body 50 is smaller than the outer diameter of the piezoelectric element 4.

従って、組立後の振動子４の周囲にコード接続部５２が
大きくはみ出さなくなり、／ＸＸトドース１のカバー３

と電源コード９との接続部の破損が防止される。よって
、ハンドピース１をより小型化することができる。さら
に、電源コード９と電極本体５０との接触がなくなり、
短絡の発生が防止される。Therefore, the cord connecting portion 52 does not protrude significantly around the vibrator 4 after assembly, and the cover 3 of the /XX todose 1
There is no contact with the cord connection part 52 and heat generation during use
This prevents damage to the connecting portion between the power cord 9 and the power cord 9. Therefore, the handpiece 1 can be further downsized. Furthermore, contact between the power cord 9 and the electrode body 50 is eliminated,
This prevents short circuits from occurring.

第１０図は、電極の第２の変形例を示している。FIG. 10 shows a second modification of the electrode.

この変形例では電極６の折曲げ部に長孔５６が設けられ

It is possible to send a large amount of water to the tip while reducing the amount of water collected. This allows for better treatment.
