Abstract

The invention discloses an abdominal wall suturing device. The abdominal wall suturing device comprises a needle core and a needle tube. An edge is formed at the front end of the needle tube. The front end of the needle tube is of an openable Y-shaped structure. The Y-shaped structure comprises two elastic opening and closing arms and a needle bar. The two elastic opening and closing arms are both connected with the front end of the needle bar. A needle hook is arranged at the front end of at least one elastic opening and closing arm. The needle bar penetrates the needle tube. By the adoption of the abdominal wall suturing device, use is convenient, rapid picking and fixing of sutures are facilitated, and the sutures can be fed into and dragged out of an abdominal cavity conveniently.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an abdominal wall stapler. Background technique [0002] Minimally invasive surgery is accepted by more and more doctors and patients because of its small wound and quick postoperative recovery. In particular, laparoscopic surgery has developed the most rapidly and has been widely used in clinical practice. For some diseases, laparoscopic surgery is used as a standard treatment. [0003] Laparoscopic surgery must use the puncture cone (trocar) to establish a working channel on the abdominal wall. The current size of the puncture cone is 5mm-12mm. Generally, the peritoneum and fascia must be sutured to prevent incision bleeding and reduce the incision when poking holes in the abdominal wall larger than 5mm. incidence of hernias. [0004] The traditional curved needle suture method cannot be completed for such a small incision, especially for obese patients. [0005] In order to solve th...
