To provide a highly safe endoscope scoop that can regulate the opening angle of the scissors and suppress excessive opening and closing of the scissors. An endoscope scissors 1 is provided with a treatment section 5 including a pair of scissors pieces 10 and 11 that are pivotally supported by a pivot shaft (support pin 13) and pivotally displaced between an open state and a closed state. The operation wire 3 connected to the treatment unit 5 and the operation unit that moves the operation wire 3 forward and backward to displace the sepals 10 and 11 between the open state and the closed state. The treatment section 5 is provided with a stopper 14 that restricts relative movement in the opening direction of the pair of hook pieces 10 and 11 in the open state and restricts relative movement in the closing direction of the pair of hook pieces 10 and 11 in the closed state. Yes. [Selection] Figure 2【課題】鋏片の開き角を規制することができ、鋏片の過剰な開放と閉止が抑制された安全性の高い内視鏡用鋏を提供する。【解決手段】内視鏡用鋏１は、回動軸（支持ピン１３）により互いに軸支されて開放状態と閉止状態とに回動変位する一対の鋏片１０、１１を備える処置部５と、処置部５に連結された操作ワイヤ３と、操作ワイヤ３を進退操作して鋏片１０、１１を開放状態と閉止状態とに変位させる操作部と、を含む。開放状態において一対の鋏片１０、１１の開き方向の相対移動を規制し、かつ閉止状態において一対の鋏片１０、１１の閉じ方向の相対移動を規制するストッパー１４が処置部５に設けられている。【選択図】図２
