PROBLEM TO BE SOLVED: To provide surgical forceps being operable under a safe load without applying excessive holding force in an operation for executing a surgical operation while holding a sensitive object such as a skin, blood vessel, muscle, and organ of a patient.SOLUTION: The forceps comprise: a pressure-sensitive sensor element engaged with a proximal end of a drive shaft that is fitted rotatably in an insertion tube and has a holding blade at a distal end a sensor pressing member fitted to a second handle member to slidingly move in parallel with the drive shaft in conjunction with the handle operation to press a surface part of the pressure-sensitive sensor element and the drive shaft slidingly moving in the insertion tube in the cross direction to open/close the holding blade at the distal end. The forceps measure changes in an electric resistance value of the pressure-sensitive sensor, and causes a control device to issue an alarm signal to appropriately control the holding force.COPYRIGHT: (C)2014,JPO&INPIT【課題】患者の皮膚、血管、筋肉、臓器などの傷つきやすい対象物を把持して外科手術等を行う操作において、過剰な把持力を与えずに安全な負荷のもとで操作が可能な外科手術用鉗子を提供する。【解決手段】挿通管内を旋回自在に取り付けられた遠端部に把持刃を有する駆動軸の近端部に感圧センサー素子を係合し、第2のハンドル部材に取り付けたセンサー押圧部材がハンドル操作に連動して駆動軸と平行にスライド移動することにより、感圧センサー素子の表面部を押しつけ駆動軸が挿通管内を前後方向にスライド移動することにより遠端部の把持刃は開閉動作をする鉗子であって、感圧センサーの電気抵抗値変化を測定して、制御装置から警告信号を発して把持力を的確に制御する。【選択図】図1
