Claims

[Claims for Utility Model Registration] (1) Consisting of a pair of upper and lower arms that can be opened and closed mutually using the same axis as a fulcrum, and a cartridge capable of accommodating a large number of gate-shaped staples can be attached and detached from the upper arm. In addition to being able to fit freely,
A suturing instrument for surgical operations, wherein the lower arm has bent recesses for receiving staple legs at positions corresponding to the gate-shaped staples held in the cartridge of the upper arm, on a surface that faces the upper arm. (2) The bent recess formed in the lower arm to receive the staple legs has a length that is approximately equal to or somewhat longer than the distance between the legs of the staple, and the recess has a length that is approximately equal to the distance between the two legs of the staple, or a length that is slightly longer than the distance between the two legs of the staple. 2. The surgical suturing device according to claim 1, wherein the suture device is slightly curved so that the deepest portion thereof is the deepest portion. (3) The ends of the portal staples filled in the cartridge are obliquely cut in the width direction, and the diagonal directions of both legs are aligned with each other to prevent the legs from colliding with each other during suturing. The suturing staple used in the surgical suturing instrument according to claim (1), characterized in that the suturing staple is oriented in the opposite direction.
