Abstract: An endoscope treatment tool includes: a cap defining a longitudinal axis and a proximal-end opening for insertion of a distal end section of an endoscope to detachably attach the cap to the endoscope; a treatment tool extending longitudinally along an outside of the cap and having a distal end configured for tissue manipulation; and a coupling member extending between the cap and the treatment tool to movably couple the treatment tool to the cap, the coupling member having high flexibility.

Abstract: An endoscope cap includes: a hood portion attached to a distal end portion of an endoscope; a cap portion connected to a distal end of the hood portion, having an abutting surface against which the endoscope is abutted in a state of the endoscope being inserted into the hood portion, and protruding from the distal end of the hood portion; a channel tube into which an elongated device is inserted; and a coupling member for coupling the device with the hood portion, the member being supported by the hood portion and extending along the hood portion. The hood portion has a pair of support holes into which the member is inserted. The member is pivotable with respect to the hood portion, with the individual support holes serving as fulcrums. The holes are formed at positions closer to a proximal end of the hood portion than the abutting surface is.

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.
