Abstract
【解決手段】ハンドル、可撓性シャフト、及びエンドエフェクタを含む内視鏡補助器具。ハンドルは、可撓性シャフト内に延在するワイヤまたはケーブル引張り部材を介してエンドエフェクタを作動させるためのアクチュエータを含む。ハンドル及びアクチュエータを片手で操作でき、ハンドルを保持している同じ手でエンドエフェクタを操作し内視鏡内に送ることができる。ハンドルは作動機構を含む。作動機構は、アクチュエータが第1の開位置にある時はエンドエフェクタの動作に影響を与えないが、アクチュエータの押圧などによってアクチュエータが第2の位置に移動するとエンドエフェクタに機能的に結合し、更にアクチュエータが第3の位置に移動するとエンドエフェクタを作動させる。
【選択図】図1
