Abstract: An endoscope treatment tool includes: a cylindrical distal-end member to be attached to a distal end of an endoscope; a grasping tool that is provided at an outer side surface of the endoscope along a longitudinal axis of the endoscope, that grasps biological tissue, and that is movable in a first direction perpendicular to the longitudinal axis in a state in which the biological tissue is grasped; an electrode that is disposed so as to protrude forward with respect to a distal end of the distal-end member; and an electrode driving portion that is configured to move the electrode in the first direction.

Abstract: A high-frequency treatment tool includes: a tubular sheath; a cap member fixed to a distal end of the sheath; and an electrode part provided so as to be relatively movable in a longitudinal direction of the sheath and relatively rotatable about a longitudinal axis of the sheath with respect to the cap member. The electrode part and the cap member are relatively rotated about the longitudinal axis of the sheath while pressing biological tissue stuck to the electrode part against the cap member to separate the biological tissue from the electrode part.
