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.COPYRIGHT: (C)2015,JPO&INPIT【課題】焼灼切開における生体組織の焼き付きによる鋏片の開閉阻害を防止し切れ味の良い内視鏡用高周波焼灼切開鋏を提供すること。【解決手段】内視鏡の処置具案内管に挿脱される可撓性シース200の先端に接続された処置部100の腕部7A及び7Bに保持されてリンク6A及び6Bによって開閉される一対の鋏片10A及び10Bが、所定寸法幅の間隔環90を介挿して軸11に軸支されることによって、前記一対の鋏片10A及び10Bを所定寸法の間隔をもって開閉し、刃面30に凹凸加工を施した内視鏡用高周波焼灼切開鋏。【選択図】図2
