Claims

[Scope of Claim for Utility Model Registration] (1) A high-frequency incision knife wire is exposed and provided on the outer surface of a flexible sheath with electrically insulating properties in front of the distal end extension, thereby forming a high-frequency incision section. In addition, in the high-frequency incision tool configured to perform suction through the sheath, a reinforcing wire is provided inside the sheath portion corresponding to the high-frequency incision portion, and the reinforcing wire is extended into the distal end extension portion of the sheath, A high-frequency cutting tool characterized in that the distal end extension of the sheath is reinforced. (2) Winding the tip of the extending portion of the reinforcing wire that extends into the tip extending portion of the sheath into a coil shape;
The high-frequency cutting instrument according to claim 1, wherein the coil portion is fitted and fixed to the inner wall of the sheath. (3) A suction aperture is formed in the side wall of the distal end extension of the sheath, and the inner wall near the aperture has a
The high-frequency cutting tool according to claim 2, which is a registered utility model, characterized in that a coil portion provided at the tip of the extending portion of the reinforcing wire is fitted and fixed. (4) The high-frequency cutting tool according to claim 2 or 3, wherein the outer surface of the reinforcing wire is coated with an electrically insulating material. (5) A request for registration of a utility model characterized in that the tip of the extending portion of the reinforcing wire is connected and fixed to a reinforcing pipe that is fitted and fixed to the inner wall of the sheath independently of the high-frequency incision knife wire. The high-frequency cutting tool according to item 1.
