PROBLEM TO BE SOLVED: To provide scissors for an endoscope which are excellent in productivity while having a stopper for regulating a maximum opening angle of a pair of scissor pieces and can respond to a case where design of the maximum opening angle is changed without increasing the number of types of components of the scissor piece.SOLUTION: Scissors 100 for an endoscope include: a flexible tube sheath 40 inserted into the inside of a body; an operation wire 30 inserted in the flexible tube sheath; a treatment part 10 equipped with a pair of scissor pieces 12, 22 which are disposed at a distal end part of the operation wire and are pivotally supported by a rotational shaft 29 to open and close with respect to each other; and an operational part which is attached to a proximal end part of the flexible tube sheath for opening and closing the pair of the scissor pieces by operating the operation wire. One scissor piece constituting the pair of the scissor pieces has stoppers 15, 16 comprising engaging parts 15a, 16a for regulating a maximum opening angle of the pair of the scissor pieces by engaging the other scissor piece and support parts 15b, 16b for fixing the engaging part on one scissor piece. The stopper is fixed to one scissor piece as the support part is inserted into a hole penetrated in a thickness direction of one scissor piece.SELECTED DRAWING: Figure 3 |
