Abstract: A suture-needle holder includes: a sheath part; a grasping portion; an operation wire; and an operation part body formed to extend along a longitudinal axis, and connected such that the sheath part is movable in a direction aligned with the longitudinal axis and rotatable around the longitudinal axis. A first groove part having a distal end and a proximal end and extending along the longitudinal axis, and a second groove part having one end connected to the proximal end of the first groove part and the other end at a position separated from the one end in the direction aligned with the longitudinal axis and in a circumferential direction of the longitudinal axis, and extending from the one end to the other end are formed in the operation part body.

Abstract: A needle holder includes: a flexible sheath portion which is capable of being inserted into an instrument channel of a flexible endoscope; a first grasping member which is rotatably coupled with a distal end portion of the flexible sheath portion; and a second grasping member which is provided in the distal end portion of the flexible sheath portion. In a state where a curved needle is grasped by a first grasping surface of the first grasping member and a second grasping surface of the second grasping member, the second grasping surface inclines such that a grasped region of the curved needle that is grasped by the first grasping surface and the second grasping surface is positioned between a distal end of the second grasping member and a needle tip of the curved needle in a direction of a center axis of the second grasping member.
