PROBLEM TO BE SOLVED: To provide a high frequency treatment implement in which overload on a slide is prevented.SOLUTION: The high frequency treatment implement includes: a flexible tube to be inserted in a body cavity a conductive operation wire freely retractably inserted in the flexible tube a treating part which is placed at a distal end part of the treating wire and treats an affected part by applying high frequency current to the treating part and an operation part which is attached to the proximal end part of the flexible tube and operates the treating part. The treating part has a slider part for operating the treating wire freely retractably and the treating wire is freely disengageably engaged with the slider part. Thus, when the slider is overloaded, the slider and the operation wire are disconnected, so that a decrease in operating performance of the treating part due to scorching of the tissues is preventable.COPYRIGHT: (C)2013,JPO&INPIT【課題】スライダに過負荷がかかることを防止する高周波処置具を提供する。【解決手段】本発明の高周波処置具は、体腔内に挿入される可撓管と、可撓管に進退自在に挿通された導電性の操作ワイヤと、操作ワイヤの先端部に配置され高周波電流の印加により患部を処置する処置部と、可撓管の基端部に付設され処置部を操作する操作部とを備える。操作部は、操作ワイヤを進退操作するスライダ部を有し、操作ワイヤは、スライダ部に係脱可能に嵌合している。これにより、スライダに過負荷がかかったときに、スライダと操作ワイヤの結合が外れるため、組織の焦げ付きによる処置部の駆動性能の低下を防止することができる。【選択図】図5
