PROBLEM TO BE SOLVED: To provide high-frequency cautery incision scissors having excellent sharpness by preventing opening/closing inhibition of scissor pieces by seizure of a biological tissue due to cautery incision.SOLUTION: A pair of scissor pieces 10A and 10B retained by arm parts 7A and 7B of a treatment part 100 and opened/closed by links 6A and 6B, the treatment part 100 being connected to a distal end of a flexible sheath 200 that is inserted/retracted with respect to a treatment tool guide tube of an endoscope, are journaled to a shaft 11 via an interval ring 90 with a prescribed dimension width. Consequently, the pair of scissor pieces 10A and 10B are opened/closed with the prescribed dimension interval, and the high-frequency cautery incision scissors include embossed blade surfaces 30. |
