Description
手術器具を提供することを目的としている。
先端から作業部が突出しているパイプと、
前記パイプよりも外側に設けられる本体部と、
前記本体部の外側に設けられるとともに、前記パイプに接続され、前記眼科用手術器具の軸方向に摺動することで前記パイプを摺動させる移動部材と、
前記移動部材に接続されるとともに、先端側部分を開閉させることによって前記移動部
材を摺動させる作動部とを有し、
前記移動部材が、前記眼科用手術器具の根元側で前記パイプに接続されているとともに
、
前記移動部材における前記作動部が接続される位置は、前記移動部材が前記パイプに接
続されている位置よりも、先端側であることを特徴とする。
また、移動部材が、眼科用手術器具の根元側でパイプに接続されていることで、補強スリーブの長さ等の構成を制限する必要が無くなる、という効果を奏する。
