A purse-string suture device

Abstract

The invention discloses a purse-string suture device. The purse-string suture device comprises a plurality of U-shaped clamps, spring pieces, suture needles, a thread and reset devices, wherein each of the spring pieces is used for connecting two adjacent U-shaped clamps to enable the U-shaped clamps to surround to form an unclosed ring; each U-shaped clamp comprises two hanging arms and a connecting arm for connecting the two hanging arms; a second through hole is formed in each connecting arm; each reset device is arranged in the corresponding second through hole, and can overcome spring force of the corresponding spring piece to enable the U-shaped clamps to array in a straight line; a first through hole is formed in each hanging arm; each suture needle is arranged in the correspondingfirst through hole; and each thread is connected with the corresponding suture needle. The purse-string suture device provided by the invention can quickly complete purse-string suture; the situationthat the needle pitch of the suture needles is uniform is guaranteed; and the quality of purse-string suture is improved, and the working load of operation doctors is reduced.

Description

technical field [0001] The invention relates to the technical field of surgical staplers, in particular to a purse string suturing device. Background technique [0002] Acute appendicitis is a common disease in general surgery and the most common acute abdomen. Once the vast majority of acute appendicitis is diagnosed, appendectomy should be performed as early as possible. After appendectomy, the cecal wall should be sutured intermittently at the base of the appendix with needle holders, suture needles, and sutures to make a purse string suture. The needle pitch of the suture needle should be uniform, so as to avoid uneven stress on the tissue and poor quality of the purse when the suture is tightened. If the quality of the purse is poor, when the cecum is edematous, the fragility of the intestinal wall tissue will increase, and the suture will not be able to hang, forming a seam laceration, which will bring unnecessary loss and pain to the patient. Appendectomy is general...

AI Technical Summary

Problems solved by technology

The needle pitch of the suture needle should be uniform, so as to avoid uneven stress on the tissue and poor quality of the purse when the suture is tightened

If the quality of the purse is poor, when the cecum is edematous, the fragility of the intestinal wall tissue will increase, and the suture will not be able to hang on it, forming a seam laceration, which will bring unnecessary loss and pain to the patient

Appendectomy is generally performed under laparoscopy. The surgical incision is small, the abdominal cavity is deep, and the needle distance of the suture needle needs to be uniform. The operation is complicated, the operation time is long, and the operation is difficult for the surgeon.
