Description
【0001】[0001]
本考案は、超音波手術器における超音波手術器用チップを振動子側本体と着脱 可能とするレンチに関し、特に白内障手術に使用される超音波チップを着脱する レンチに関する。 The present invention relates to a wrench that allows an ultrasonic surgical instrument tip in an ultrasonic surgical instrument to be attached to and detached from a transducer body, and more particularly to a wrench that attaches and detaches an ultrasonic tip used in a cataract surgery.
【0002】[0002]
超音波手術器は、振動子からの超音波振動を超音波チップに伝達して、チップ 先端部の超音波振動により生体組織を破砕するものである。 The ultrasonic surgical instrument transmits ultrasonic vibrations from a vibrator to an ultrasonic tip, and crushes living tissue by the ultrasonic vibrations at the tip of the tip.
【0003】 ここで、上記超音波チップにおいては、図6に示すように、振動子側本体と着 脱自在とするため根本端部にネジ溝部90が形成され、このネジ溝部90を介し て振動子(図示せず)と一体形成された伝達管(図示せず)に着脱される。更に 、超音波チップのネジ溝部90の手前側にはほぼ筐状のレンチフック部91が形 成されている。Here, in the ultrasonic chip, as shown in FIG. 6, a thread groove portion 90 is formed at a root end portion so as to be attachable / detachable to / from the vibrator-side main body, and vibration is generated through the screw groove portion 90. It is attached to and detached from a transmission pipe (not shown) integrally formed with the child (not shown). Further, a substantially wrench hook portion 91 is formed on the front side of the screw groove portion 90 of the ultrasonic chip.
【0004】 ここで、従来の超音波チップ用レンチBにおいては、レンチBが凹状の切欠部 95を有し、該切欠部95を超音波チップのレンチフック部91に嵌合させて、 超音波チップを長手方向の軸線を中心にして回転させて、伝達管に固定させてい た。また、上記形状に係る超音波チップを取り付けるレンチとして、円盤状の部 材に単に四角形状の穴部を設けたものもある。更に、円錐形状のレンチフック部 を有する超音波チップにおいては、円盤上部材に円形の穴と爪を設けたレンチが あり、該円形の穴に超音波チップを挿入して、上記爪を超音波チップのレンチフ ック部に設けられた溝部に嵌合させて取付けを行う。Here, in the conventional ultrasonic tip wrench B, the wrench B has a concave cutout portion 95, and the cutout portion 95 is fitted into the wrench hook portion 91 of the ultrasonic tip to make the ultrasonic wave. The tip was rotated around the longitudinal axis and fixed to the transfer tube. Further, as a wrench for mounting the ultrasonic tip having the above-described shape, there is also a wrench in which a square hole is simply provided in a disk-shaped member. Further, in an ultrasonic tip having a conical wrench hook part, there is a wrench provided with a circular hole and a claw on the disk member, and the ultrasonic tip is inserted into the circular hole to make the claw ultrasonic wave. Attach by fitting it into the groove provided on the wrench hook of the chip.
【0005】[0005]
しかしながら、従来の超音波チップ用レンチにおいては、超音波チップのレン チフック部やレンチそれ自体が破損するという問題が生じていた。すなわち、ほ ぼ筐状のレンチフック部を有する超音波チップ用レンチの場合には、超音波チッ プを伝達管等の振動子側本体に取り付けるために回転させて締める際に、ほぼ筐 状のレンチフック部の角部がレンチの切欠部若しくは穴部の側面に当たり、ナメ やバリを生じる。また、円錐形状のレンチフック部を有する超音波チップ用レン チにおいても、レンチが超音波チップに当接する部分が爪の部分のみであるため 、爪部分に過大な負荷が掛かり、爪や溝部にナメが生じたり、バリが生じたりす るという問題があった。 However, in the conventional ultrasonic tip wrench, there has been a problem that the lent hook portion of the ultrasonic tip and the wrench itself are damaged. That is, in the case of an ultrasonic tip wrench having a substantially casing-shaped wrench hook portion, when the ultrasonic tip is rotated and tightened to be attached to the transducer-side main body such as the transmission tube, the ultrasonic tip has a substantially casing-like shape. The corner of the wrench hook hits the side of the notch or hole of the wrench, causing slack and burrs. In addition, even in the case of an ultrasonic tip rench having a conical wrench hook, since the only part of the wrench that comes into contact with the ultrasonic tip is the claw, an excessive load is applied to the claw and the claw and groove are There were problems such as blister and burr.
【0006】 ここで、白内障手術においては、患部である眼内(角膜内部)の洗浄及び冷却 、眼球前房内の圧力維持、また破砕組織吸引を行うために、超音波チップを包囲 する保護管を設け、該超音波チップと保護管の間に灌流液を流して、眼内に灌流 液を供給して手術を行う術式があるが、超音波チップやレンチにナメやバリ等の 損傷があると、眼内に金属片も流入してしまい患者に危険である。また、金属片 が発生しなくても、超音波チップにバリがあると、術者の手術用グローブを傷付 けてしまい、清潔を保つ上で支障となる。Here, in cataract surgery, a protective tube surrounding an ultrasonic tip for cleaning and cooling the affected part of the eye (inside the cornea), maintaining the pressure in the anterior chamber of the eye, and aspirating crushed tissue. There is a surgical procedure in which a perfusate is flown between the ultrasonic tip and a protective tube to supply the perfusate into the eye to perform surgery, but damage to the ultrasonic tip or wrench such as burrs or burrs may occur. If so, metal fragments will also flow into the eye, which is dangerous to the patient. Even if no metal piece is generated, if the ultrasonic tip has burrs, the surgical glove of the operator will be damaged, which will be an obstacle to keeping cleanliness.
【0007】 そこで、本考案は、超音波チップの振動子への着脱に際して、超音波チップの レンチフック部やレンチのナメやバリ等の破損を生じることがなく、患者に危険 を伴わない超音波チップ用レンチを提供することを目的とするものである。Therefore, the present invention does not cause damage to the wrench hook portion of the ultrasonic tip or the wrench or burrs of the wrench when the ultrasonic tip is attached to or detached from the transducer, and the ultrasonic wave is not dangerous to the patient. It is intended to provide a tip wrench.
【0008】[0008]
本考案に係る超音波チップ用レンチは、ほぼ円錐形状のレンチフック部を有す る超音波チップを振動子側本体と着脱自在とする超音波チップ用レンチにおいて 、上記ほぼ円錐形状のレンチフック部のほぼ円錐曲面に密着するほぼ円錐曲面と 、上記レンチフック部に設けられた溝部に嵌合する爪部とを有することを特徴と するものである。 The ultrasonic tip wrench according to the present invention is an ultrasonic tip wrench in which an ultrasonic tip having a substantially conical wrench hook portion can be attached to and detached from the transducer side body. It has a substantially conical curved surface that closely adheres to the substantially conical curved surface, and a claw portion that fits into the groove portion provided in the wrench hook portion.
【0009】[0009]
本考案における超音波チップ用レンチにおいては、超音波チップにおけるほぼ 円錐形状のレンチフック部のほぼ円錐曲面に密着するほぼ円錐曲面と、該根本部 に設けられた溝部に嵌合する爪部とを有するので、レンチフック部のほぼ円錐曲 面と本考案のレンチにおけるほぼ円錐曲面とが広く密着するため、レンチと超音 波チップとが密着する面積が増大するため、レンチの爪部とレンチフック部の溝 部に掛かる負荷が軽減し、ナメやバリが生じにくくなる。 In the wrench for the ultrasonic tip according to the present invention, a substantially conical curved surface that closely adheres to the substantially conical curved surface of the substantially conical wrench hook portion of the ultrasonic tip and a claw portion that fits into a groove provided in the root portion are provided. Since the wrench hook portion has a substantially conical curved surface and the substantially conical curved surface of the wrench of the present invention in wide contact with each other, an area in which the wrench and the ultrasonic tip are in close contact with each other is increased. The load on the groove part of the part is reduced, and it becomes difficult to cause sludge and burrs.
