本発明は超音波を利用して生体内に生じた結石を破壊す
るための超音波砕石グローブに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ultrasonic lithotripsy glove for destroying stones formed in a living body using ultrasonic waves.
一般に、この超音波砕石プローブは振動子の振動をホー
ン部で増幅し、これを長軸方向の振動として長尺な振動
伝達部材全通じてその先端に伝播するように構成されて
いる。そして、振動する振動伝達部材の先端に結石を当
て砕石するものである。Generally, this ultrasonic lithotripter probe is configured to amplify the vibration of a vibrator in a horn section and propagate the vibration in the longitudinal direction through the entire length of a long vibration transmission member to its tip. Then, the stone is crushed by hitting the tip of the vibrating vibration transmission member.
上記従来の超音波砕石グローブでは振動伝達部材の長軸
方向の振動で砕石を行なうため、たとえは結石が硬く大

完全に破砕することが難しくな夛、このため、放電破壊
や鉗子を用いた破砕を併用しなければならないという不
都合があった。また、手術中にこれらの器具の交換を頻
繁に行なう場合、きわめて煩雑な作業を伴う。In the conventional ultrasonic lithotripsy glove described above, stones are crushed by vibrations in the longitudinal direction of the vibration transmission member, so if the stone is hard and large, the stone may have a large potting effect, and although it may create a hole in the stone, it is not effective in crushing the stone. That's enough. Therefore, it is difficult to completely crush the calculus, which is disadvantageous in that discharge destruction and crushing using forceps must be used together. Furthermore, if these instruments are frequently replaced during surgery, it is extremely complicated.
本発明は上記問題点に着目してなされたもので、その目
的とするところは結石に対する穴あけ効果に加えて粉砕
効果金高め、破砕効率の高い超音波砕石プローブを提供
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 lithotripter probe that not only has a drilling effect on stones but also improves the crushing effect and has a high crushing efficiency.

で連結した構成である。[Means and operations for solving all the problems] In order to solve all the above problems, in the ultrasonic lithotripsy probe of the present invention, when the imaging transmission member is connected to the horn, the center line of the imaging transmission member is aligned with the horn. This is a configuration in which they are connected at positions that are offset from the center line of vibration and do not coincide with each other.
したがって、伝動伝達部材にはその長軸方向の撮動に加
えて径方向の撮動も起き、結石の破砕力を高める。Therefore, in addition to the movement in the longitudinal direction, the power transmission member also moves in the radial direction, increasing the stone crushing force.

うになっている。By the way, in the ultrasonic stone crushing glove 1, the vibration transmitting member 11 is located between the center line t1 and the vibration center line t of the hoe 78.
2 are eccentrically connected. That is, the base end portion of the vibration transmitting member 11 is fixed to the connecting member 9 by brazing rather than eccentrically. The connecting member 9 is detachably fixed to the tip of the horn 8 with a screw.
次ｐｃ、上記構成の超音波砕石ブローｆノの作用を説明

この振動はホーン８で増幅されて振動伝達部材１１’１
通じてその先端へと伝播する。The insertion portion 3 of this ultrasonic lithotripsy glove 1 is filled with physiological saline (mη) through a sheath (not shown) and a scope with a treatment tool (not shown).
For example, it is inserted into the renal capsule. When a voltage is applied to the piezoelectric element I5 from a power source (not shown) through the power cord 6, ultrasonic vibration is generated in the vibrator 15,
This vibration is amplified by the horn 8 and the vibration transmission member 11'1
and propagates to its tip.
ここで、振動伝達部材１１の先端に結石２５を押し当て
ると、その超音波振動が砕石力となり、その結石２５を
粉砕する。Here, when the calculus 25 is pressed against the tip of the vibration transmitting member 11, the ultrasonic vibration becomes a crushing force and crushes the calculus 25.
この場合、振動伝達部材１１の中心線ｔ１はランジ−パ

ＶＣ対してその径方向の破砕力が生じ、主として粉砕効
果として作用する。したがって、結石２５が硬く大きな
場合であっても確実に粉砕することが可能でおる。In this case, the center line t1 of the vibration transmission member 11 is the vibration center line t! of the lunge-pan type vibrator 5 and the horn 8! Since it is eccentric from the center, disturbance occurs in the propagation of vibrations, and vibrations occur in the vibration transmission member 11 not only in its longitudinal direction but also in its radial direction. The vibrations in the longitudinal direction mainly act as a drilling effect on the stone 25, as shown in FIG. In addition, the vibration in the radial direction is caused by the stone 25 as shown in Fig. 5.
A radial crushing force is generated on the VC and acts primarily as a crushing effect. Therefore, even if the stone 25 is hard and large, it can be reliably crushed.

ｂｔ起すことなく、後方へ送られて円滑に排出できる。Further, the stone fragments 26 of the calculus 25 crushed in this manner are discharged from the body together with the irrigation fluid through the inner hole 22 and through hole 21 of the vibration transmission member 11 under the suction action of a suction pump (not shown). . Furthermore, the stone piece 26
As shown in FIG. 6, when the material passes through the inner hole 22 of the vibration transmission member II, it receives vibrations in the radial direction from the vibration transmission member 11, so that it is further finely pulverized. Therefore, the stones can be sent to the rear and smoothly discharged without causing stones.

であっても良い。In addition, in the above embodiment, the center line 1. of the vibration transmission member 11. The vibration center line 1 of the horn 8 of the vibrator 5 was in a positional relationship in which they were parallel and offset in an eccentric state, but in the present invention, it is sufficient that the center lines t1 + tz do not deviate and match. . Therefore, for example, as shown in FIG. 7, the center lines L 1 + tz may intersect at a point P at an angle. Alternatively, the relationships may be contradictory without intersecting.
