PROBLEM TO BE SOLVED: To provide a high-frequency incision instrument for an endoscope which safety makes an incision procedure without substantial displacement in a rod-like electrode relative to the viable tissue under incision in spite of a sudden fluctuation in the relative positional relation between the incision instrument and the viable tissue in the middle of the incision procedure. SOLUTION: The high-frequency incision instrument for endoscope which can supply high-frequency current to the rod-like electrode 3 protruding forward from the distal end of an electrically insulative sheath 1 is constituted by forming the rod-like electrode 3 of a conductive-metal stranded wire. |
