形となることを特徴とする内視鏡用処置具。 A treatment section configured to be expandable and contractible is connected to the tip of an operation wire that is inserted into the sheath so that it can be freely advanced and retracted, using an elastic wire that has a plurality of bending points.
This endoscopic treatment instrument in which the treatment section is put in and taken out from the distal end of the sheath has a plurality of elastic wire parts extending from the distal end to the proximal end, and the distal end and the proximal end of each elastic wire part. are tied together to form a treatment section, and first to fifth bending points are formed in the middle part from the distal end to the proximal end of each elastic wire section, and the first to fifth bending points are formed at the most distal end and the last The fifth bending point at the end is formed by bending inward, the second to fourth bending points are formed by bending outward, and the fifth bending point and each elastic wire part are tied together on the proximal side. The elastic wire portion between the parts is formed gently with respect to the central axis of the treatment part, and all sides between the bending points are at an angle with the central axis when the treatment part is protruded from the sheath. 1. An endoscopic treatment instrument, characterized in that the treatment section is inclined at a substantially octagonal shape.
