Abstract: A medical manipulator includes a multi-lumen tube including a flexible portion and a bending portion at a distal end of the flexible portion, a distal-end portion at a distal end of the bending portion, a proximal-end portion at a proximal end of the flexible portion, wires causing the bending portion to be bent, a reinforcement coil one end thereof being secured to the distal-end portion and the other end thereof being secured to the proximal-end portion, a flexible-portion cover member, and a bending-portion cover member formed more flexible than the flexible-portion cover member. The flexible and bending portions include a first lumen passing through the tube and into which the coil is inserted, and second lumens passing through the tube at positions farther outside than the first lumen is and into which the wires are inserted. The coil is disposed along an inner surface of the first lumen.

Abstract: A sufficient gripping force is exerted on a suture thread through an easy process. Provided is a ligation thread fastening tool including: a gripper that has a pair of crimp pieces opposed to each other with a space therebetween and whose inner faces opposed to each other are to be crimped together and that has, between the inner faces, a groove into which a suture thread can be inserted from a first side of the crimp pieces toward a second side thereof; and an accommodation portion that is provided in the gripper from the inner face outward of the groove so as to communicate with the groove and that accommodate an end portion of the suture thread inserted thereinto from the first side through the groove.
