Endoscope treatment tool

Abstract

Provided is an endoscope treatment tool including: a tubular distal-end member that is attached to the distal end of an endoscope; an outer sheath having a channel extending in a direction along a longitudinal axis of the endoscope; a treatment-tool body; a linear connector that connects the distal-end member and the treatment-tool body. The treatment-tool body includes a bendable long insertion portion that is inserted through the channel, a treatment portion with which treatment is performed, and a rotating member. The rotating member includes a through-hole that extends along a plane intersecting the longitudinal axis and through which the connector is inserted. When the treatment-tool body is pushed in the longitudinal direction, the connector guides the treatment portion along a locus centered on an axis intersecting a plane including the axis of the distal-end member and the axis of the channel.
