PROBLEM TO BE SOLVED: To smoothly perform a mucus membrane separating treatment by easily adjusting the direction of a mucus membrane shoving member relative to a high-frequency treatment instrument without shading an observation visual field of an endoscope in the high-frequency treatment instrument for the endoscope wherein the mucus membrane shoving member of such a shape that the distal end of one rod is curved is juxtaposed with the high-frequency treatment instrument.SOLUTION: A distal end guide member 4 made of an electricity insulation material for guiding distal end portions of two treatment members 2 and 3 projecting from the distal end of a flexible sheath 1 is provided at the distal end of the flexible sheath 1 in such a way as rotatable around an axis of the distal end of the flexible sheath 1. A high-frequency treatment member guide hole 5 for guiding a straight rod-shaped high-frequency treatment member 2 and a shoving member guide hole 6 for guiding a one-rod-shaped mucus membrane shoving member 3 which is curved obliquely forward are formed side by side to penetrate in the distal end guide member 4.COPYRIGHT: (C)2014,JPO&INPIT【課題】一本のロッドの先端を湾曲させた形状の粘膜片押し退け部材が高周波処置具と併設された内視鏡用高周波処置具において、内視鏡の観察視野を遮ることなく高周波処置具に対する粘膜片押し退け部材の向きの調整を容易に行って、粘膜剥離処置をスムーズに行うことができるようにする。【解決手段】可撓性シース1の先端部分に、可撓性シース1の先端から突出する二つの処置部材2,3の先端部分を案内するための電気絶縁材からなる先端ガイド部材4が、可撓性シース1の先端部分の軸線周り方向に回転自在に設けられ、先端ガイド部材4には、真っ直ぐなロッド状の高周波処置部材2を案内するための高周波処置部材案内孔5と、斜め前方に向かって湾曲した一本のロッド状の粘膜片押し退け部材3を案内するための押し退け部材案内孔6とが並んで貫通形成されている。【選択図】 図1
