Abstract
Description
本発明の第1の実施形態について、図1乃至図8を参照して説明する。図1は、本実施形態の処置システム1を示す図である。図1に示すように、処置システム1は、高周波処置具2と、高周波処置具2へのエネルギーの供給を制御するエネルギー制御装置3と、を備える。ここで、図1において、矢印C1側を先端側とし、矢印C2側(先端側とは反対側)を基端側とする。
なお、第1の実施形態では、エンドエフェクタ7は、一対の把持片15,16を備えるが、これに限るものではない。例えば、図9に示すある変形例では、エンドエフェクタ8は、ブレード状の電極40から形成されている。本変形例では、電極40は、外表面43を有する。電極40の外表面43には、幅方向(矢印Wの方向)について一方側の縁に第1の側方ブレード45が形成され、幅方向について他方側の縁に第2の側方ブレード46が形成され、先端側(矢印C1側)の縁に先端ブレードが形成されている。また、電極40の外表面43には、厚さ方向(図9において紙面に対して垂直な方向)の一方側を向く第1の面48と、第1の面48とは反対側を向く第2の面(図示しない)と、が形成されている。本変形例では、少なくとも第1の面48にコーティング35が被覆されている。図9では、コーティング35は、ドット状のハッチングで示されている。
