PROBLEM TO BE SOLVED: To provide a treatment tool for endoscope with which an open and close operation may be certainly executed by reducing pulling force or pushing force which should be provided to an operation wire.SOLUTION: A treatment tool for endoscope (treatment tool) 100 comprises a pair of holding pieces 12, 22, a rotational axis 39, an operation wire 30 and a plurality of slide parts 60a to 60c. The holding pieces 12, 22 respectively comprise conductive cutting parts 13, 23 holding living tissue on tip end parts. The rotational axis 39 openably/closably journals the holding pieces 12, 22 superposed in an opposing manner to each other. The operation wire 30 operates opening and closing of the cutting parts 13, 23 by providing driving power to base end parts 122, 222 of the holding pieces 12, 22. The slide parts 60a to 60c are arranged at several positions on periphery of the rotational axis 39 and sandwiched by the holding pieces 12, 22. The slide parts 60a to 60c slide in a state where they respectively contact to at least one of the holding pieces 12, 22 on a point.SELECTED DRAWING: Figure 3 |
