Abstract

See full text

An endoscope treatment tool includes: a cylindrical cap attached to an outer side of a distal-end section of an endoscope and having first and second radial directions intersecting each other; a treatment tool supported at an outer side of the cap in the first radial direction to be movable in the longitudinal direction; and a linear flexible coupling member coupling the treatment tool with the cap such that the grasper reaches a position where the grasper protrudes from a distal end of the cap. A swing section of the coupling member couples the cap with the treatment tool to allow relative movement in the second radial direction, and, in response to pressed forward in the longitudinal direction by the treatment tool, swings about a swing axis extending in the second radial direction while generating a tensile force and bending the treatment tool inward in the first radial direction.
