    摘要： A medical-treatment-tool according to the present invention is provided with: a inserting-portion; a gripping-piece pivots about a shaft orthogonal to a longitudinal axis of the inserting-portion; a driving-portion generates a motive power with which the gripping-piece is driven; a first motive-power transmitting member transmits the motive power to the inserting-portion; a motive-power amplifying mechanism amplifies the motive power; a pulley secured to the shaft of the gripping-piece; a wire-like second motive-power transmitting member wound around the pulley, transmits amplified the motive power to the pulley, and rotates the pulley about the shaft, thus causing the gripping-piece to be pivoted. The motive-power amplifying mechanism is a movable-pulley supported to move in a direction along the longitudinal axis of the inserting-portion, the first motive-power transmitting member is a wire-like member wound around the movable-pulley, and end of the second motive-power transmitting member is attached to the rotation shaft of the movable-pulley.

    摘要： A medical stapler includes a first and a second grippers that are provided so as to be capable of opening/closing with respect to each other, and that can grip tissue therebetween. The first gripper includes a first contact surface being made to come into firm contact with one side of the tissue, and an ejection hole that is provided in the first contact surface and from which a staple is ejected. The second gripper includes a second contact surface being made to come into firm contact with the other side of the tissue, and an anvil portion provided in the second contact surface and having a curved surface that causes a needle portion of the staple to be bent. The first and second grippers are provided so as to allow relative positions thereof to be adjusted in a tangential direction of the curved surface.
