PROBLEM TO BE SOLVED: To easily and accurately give treatment to an affected part from a short distance by forming a large diameter part projecting outward near the boundary part of a tip operation part and a sheath. SOLUTION: A treating implement 10 is constituted by connecting the tip operating part 30 to the tip part of a flexible sheath 20 to transmit a high-frequency current to the part 30 through an operation wire 21 inserted into the sheath 20. The sheath 20 is constituted by covering the outer periphery of a tightly wound coil pipe 22 with an electrically insulating synthetic resin flexible tube 23, and the part 30 is constituted by arranging a linking mechanism 32 operated by the wire 21 from remote and an opening/closing member 33 opened/ closed by the mechanism 32 at the tip main body 31 connected to the tip of the pipe 22. Then, a projecting part 31a projecting in the state of a flange is formed at the rear tip part of the main body 31 connected to the pipe 22 and the external surface part of an external tube 23 covering the part 31a is made as a largest diameter part A having the largest diameter in the neighborhood. |
