PROBLEM TO BE SOLVED: To provide a clip being opened largely and yet facilitating fine handling, and a treatment instrument for endoscopes including the clip mounted thereon.SOLUTION: A clip 200 is used for a treatment instrument for an endoscope. The clip 200 comprises: a first locking part 30 to be engaged with a tip end of an operation wire included in the treatment instrument for the endoscope; a plurality of arm portions 40 that are provided at a distal side with respect to the first locking part 30, opened outward by self-expanding force, and closed by displacement of a fastening member moving from a proximal side relative to the distal side; and a plurality of tip claws 49 provided at a distal side with respect to the plurality of arm portions 40 and projecting inward. Further, each arm portion 40 includes a curved portion 42 that is curved outward such that a curvature radius of the proximal side becomes larger than a curvature radius of the distal side.SELECTED DRAWING: Figure 2 |
