PROBLEM TO BE SOLVED: To provide a high-frequency dissection and abscission tool which can easily hang a loop part of a wire for dissection on a lesion part even when there exists an obstruction such as a wrinkle and a curved part on this side of the lesion part and can surely bind the lesion part and can rapidly perform dissection and abscission of the lesion part. SOLUTION: A high-frequency dissection and abscission tool is provided with a insulative flexible tube 2 with an inner layer, an outer layer and a blade embedded between them and formed with a curved part 16 at its apex, an operational wire member 9 being freely forward and backward inserted in the flexible tube 2 and a high-frequency processing part 12 with a high-frequency dissection wire 11 provided at the apex of the operational wire member 9 so as to be freely projected and sunk from the apex of the flexible tube 2 and being formed into a loop shape being opened and closed by an action of projection and sinking. After the curved part 16 of the flexible pipe 2 is projected from the apex of an endoscope, the apex side of the flexible tube 2 is rotated by rotating this side of the flexible tube 2 to position the apex of the curved part 16 of the flexible tube 2 at the inner part over a wrinkle and a curved part being obstructions. |
