PROBLEM TO BE SOLVED: To provide a bipolar type heating treatment device for endoscope comprising good operation property and thin outer diameter, without attaching a counter electrode board to an extracorporeal part.SOLUTION: There is provided a bipolar type heating treatment device for endoscope which opens and closes a treatment instrument 4 formed of a pair of stationary blade 4a and movable blade 4b by forward/backward movement of an operation wire 5, feeds heating current to the treatment instrument 4 through a coaxial cable 90 for heating a space between the stationary blade 4a and the movable blade 4b being an electrode. The bipolar type heating treatment device for endoscope comprises: a wire guide 91 which is formed of a large annulus part F which is fitted to an external conductor C of the coaxial cable 90, and a small annulus part E whose outer periphery contacts the large annulus part and penetrates the large annulus part while conducting to the operation wire； an annulus frame part 4e which penetrates an internal conductor A and conducts thereto； a stationary blade 4a for conducting to the frame part 4e； and a movable blade 4b engaged to the operation wire 5 which penetrates the small annulus part E of the wire guide 91 and provided on the other end.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】対極盤を体外に張る必要がなく外径が細く操作性の良い内視鏡用バイポーラ型加熱処置装置を提供すること。【解決手段】操作ワイヤ５の進退によって一対の固定刃４ａ及び可動刃４ｂから成る処置具４を開閉し、加熱電流を同軸ケーブル９０を介して処置具４に給電することにより電極である固定刃４ａ及び可動刃４ｂの間を加熱する内視鏡用バイポーラ型加熱処置装置であって、同軸ケーブル９０の外部導体Ｃと嵌合する大円環部Ｆ及び該大円環部と外周が接して操作ワイヤと導通しながら貫通する小円環部Ｅから成るワイヤガイド９１と、内部導体Ａを貫通して導通する円環状の枠部４ｅと、該枠部４ｅに導通する固定刃４ａと、ワイヤガイド９１の小円環部Ｅを貫通した操作ワイヤ５と係合し、他端に設けられた可動刃４ｂとを備える。【選択図】図３
