Abstract:
1. Scissors for an endoscope, comprising: a treatment section including a pair of scissor elements which are pivotably supported by a pivoting shaft and are pivotally displaced between an open position and a closed position; an operation wire connected to the treatment section; and an operation section for displacing the scissor elements between the open position and the closed position by advancing and retracting the operation wire, wherein a stopper is provided at the treatment section, which restricts the relative movement between the pair of scissor elements in the opening direction when the scissor elements are in the open position, while restricting the relative movement between the pair of scissor elements in the closing direction when the scissor elements are in the closed position; and wherein the stopper is provided on at least one of the pair of scissor elements in such a manner that when the scissor elements are in the closed position, the stopper abuts a blade formed on the inner side of the other scissor element anteriorly to the pivoting shaft and that when the scissor elements are in the open position, the stopper abuts an arm of the other scissor element which extends to rearward of the pivoting shaft.
