Abstract
A treatment instrument for an endoscope includes a main body, a cutting wire and an insertion portion. The cutting wire has an insertion portion inserted in the main body and an exposed portion situated at a distal side of the insertion portion and exposed out of the main body. The cutting wire is supplied with high-frequency current, and the insulating member electrically insulates a peripheral surface of the cutting wire. The insulating member insulates that part of the exposed portion, which is other than a non-insulated portion extending in a range of 5 mm to 15 mm from a distal end of the exposed portion. The excision portion is formed of the non-insulated portion of the cutting wire.
