    摘要: The knife has the flexible, electrically insulating casing (24) inserted into a body cavity via an endoscope. A wire within this casing receives the HF current from a HF source and can be displaced to project relative to a suction opening (38) at the distal end of the casing to define the cutting zone (42).The operating device at the proximal end of the casing has a suction mouthpiece coupling to the suction opening (38). The casing is strengthened via an inserted support ring (56) between the suction opening (38) and the cutting zone (42) and/or via an internal strengthening wire (50).ADVANTAGE--Prevents blockage of suction path during bending.

    摘要: 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.
