Claims

[Scope of Claim for Utility Model Registration] (1) Forceps comprising an operating part body and an insertion part connected to the body cavity for insertion into a living body cavity, through which an electric scalpel connected to a high-frequency power source is inserted. A channel is formed, and a spiral groove is carved on the entire outer periphery of the forceps channel tube constituting the forceps channel, or a spiral groove is carved only on the outer periphery corresponding to the angle part of the forceps channel tube. A coiled spring is wound around the outer periphery of the forceps channel tube, and a terminal plate to which a lead wire is fixed is brought into contact with the coiled spring on the operating section main body side of the coiled spring to electrically connect the coiled spring. An endoscope characterized in that leakage current from an electric scalpel is returned to a high frequency power source. (2) Within the scope of claim 1 of the utility model registration claim, the terminal board is placed on a coiled spring wrapped around a forceps channel tube and fixed by being clamped with a heat shrink tube. Endoscope. (3) The terminal plate is made into two parts of a cylindrical body with a flange,
Shift each of the cut ends of the flanges so that they match the pitch of the coiled spring wrapped around the forceps channel tube, and screw the cylindrical terminal plate cut into two parts between the tube and the spring to secure contact. The endoscope according to claim 1 of the utility model registration claim, characterized in that: (4) A claim for utility model registration characterized in that the terminal plate is cylindrical, and the cylindrical terminal plate is sandwiched between a forceps channel tube and a coiled spring wound around the tube. The endoscope according to item 1.
