Patent ID: 10729425

Abstract:
A suture device including: an elongated shaft member; a pair of gripping members; and a passing mechanism that transfers a suture needle between the gripping members, wherein the passing mechanism is provided with fitting holes provided in the individual gripping members and to which the suture needle is fitted, holding members that are inserted into recessed portions in outer circumferential surface of the suture needle by being pulled toward the proximal end sides thereof in directions that intersect axes of the individual fitting holes, a swing member that is provided so as to be swingable about an axis that is orthogonal to the longitudinal axis, a pair of tensile-force transmitting members that transmit tensile forces that cause the swing member to be swung, axial-force transmitting members that transmit axial forces associated with swinging of the swing member, and hold-state maintaining mechanism that maintains the holding members in the recessed portions.
