Abstract

A suture device for suturing tissue by using a suture unit having an anchor attached to an end of a suture thread. The suture device is provided with a pair of a first jaw and a second jaw which are configured so that the jaws can clamp the tissue by opening and closing with respect to each other, a hollow needle tube capable of containing the anchor in the cavity of the hollow needle tube, and a pusher inserted through the needle tube in an advanceable and retractable manner and capable of pushing the anchor, which is contained in the needle tube, to the tip side of the needle tube. The needle tube is mounted so that the needle tube intersects the first jaw and so that the tip of the needle tube is directed to the second jaw. When the first jaw and the second jaw clamp the tissue, the needle tube is punctured into the tissue.

Description

technical field [0001] The present invention relates to a stapler used for insertion into a body cavity. More specifically, the present invention relates to a stapler used for suturing a perforation formed in a luminal organ such as the stomach or the intestine by using a suture thread with a retainer attached to its end. , and a suturing system containing the stapler. Background technique [0002] Conventionally, for the purpose of suturing a perforation or a tear formed on a luminal organ such as the stomach or the intestine, a stapler using a suture thread with a fixer attached to its end is known (for example, refer to Patent Document 1). In this stapler, the fixer ejected from the front end of the needle is locked in the tissue or outside the tissue to the tissue around the perforation, and the suture thread is tightened with a stopper or the like, and the tissue with the fixer locked is drawn closer. And suture. [0003] Patent Document 1: International Publication N...
