Description
有利には、刃手段は、導波管拡張部材の湾曲面に対してほぼ垂直な面内に延出する。
拡張部材の直径は、第1導波管の直径の半分ほどである。
導波管拡張部材の湾曲は、その先端及びそれによって携えられる刃手段が、第1導波管の軸から、第1導波管の半径と等しい距離を越えて延出しないようにされてよい。
本発明の一実施形態を、一例として、また添付の図面を参照して、以下により詳細に説明する。
次に図面を参照すると、図1は、長手軸2を中心として捩り振動可能な導波管1の先端における出力体の平面図であり、また図2は側面図である。
拡張体3は、その先端にある作用面が軸2から、最初の出力体の直径D1の突出部よりも遠くに延出しないように、一面内においてその先端付近で湾曲させられる。
出力体の使用は、幾つかの重要な特徴を提供する。
る。
第3に、集束させられたエネルギは、対象組織部位において有効な血液停止をもたらすために、作用ヘッドが、外科医により案内されるのを許容する。半径方向に延出させられたローブの面内における出力体部分の湾曲は、関節包が結合された大腿骨頭等の湾曲構造体への接近を許容する。
Claims (7)
- 捩りモードにおいて振動可能な超音波手術器具と共に使用する出力体手段であって、該出力体手段は円柱状の導波管と、該導波管には、先端に、前記導波管の直径より小さい直径を有する導波管拡張部材が備えられると共に、該導波管拡張部材は一平面内において該導波管の軸から湾曲させられており、該導波管拡張部材の先端から半径方向に延出する少なくとも2個の刃手段とを含み、
前記少なくとも2個の刃手段が4個のポケットを含み、該ポケットが、周囲の組織に対して集束させられた圧縮波を発すべく円柱状断面を有するよう形成されていることを特徴とする出力体手段。 - 前記出力体手段には、互いにほぼ正反対となるように半径方向に延出する2個の刃手段が備えられることを特徴とする請求項1に記載の出力体手段。
- 前記刃手段は、前記一平面に対してほぼ直交する方向に延びる面に沿って延出することを特徴とする請求項1又は2に記載の出力体手段。
- 前記導波管拡張部材の先端は丸くされており、前記刃手段は、逆方向に作用可能であることを特徴とする請求項1乃至3のいずれか一項に記載の出力体手段。
- 前記導波管拡張部材の直径は、前記導波管の直径の半分であることを特徴とする請求項1乃至4のいずれか一項に記載の出力体手段。
- 前記導波管拡張部材の湾曲は、該導波管拡張部材の先端及び該先端によって支持される前記刃手段が、前記導波管の軸から、該導波管の半径と等しい距離を越えて延出しないようにされることを特徴とする請求項1乃至5のいずれか一項に記載の出力体手段。
- 捩りモード超音波振動を生じさせる手段と、請求項1乃至6のいずれか一項に記載の出力体手段とを含む手術器具。
