Suture line-equipped suture needle for gastrointestinal endoscope surgery

Abstract

The invention discloses a suture line-equipped suture needle for a gastrointestinal endoscope surgery. The suture needle comprises a suture needle and a suture line connected to a tail end of the suture needle, the tail end of the suture needle is shaped like a hollow tube, the suture line is provided with barbs, and the barbs are arranged on the suture line in a spiral direction; after one end ofthe suture line is inserted into the hollow tube of the tail end of the suture needle, a tube wall of the hollow tube is clamped and pressed, the suture line is connected to the tail end of the suture needle, and the other end of the suture line is provided with a slippage preventing structure. The suture needle for the gastrointestinal endoscope surgery disclosed in the invention is provided with the barb line; the suture needle can be placed in a gastrovascular cavity after going through a narrow and long clamp path and then taken out, and knotting operation can be eliminated.

Description

technical field [0001] The present invention relates to a medical operation instrument, more specifically, relates to a suture needle with a suture thread for digestive endoscopic surgery. Background technique [0002] Malignant tumors of the digestive tract are common and frequently-occurring diseases of the digestive tract, which have seriously threatened human life and health. As the society gradually enters the aging stage, the detection rate of malignant tumors of the digestive tract also increases. The tumor can be resected by endoscopic minimally invasive treatment, and a radical effect can be achieved. [0003] With the continuous development of digestive endoscopy and endoscopic diagnosis and treatment technology, endoscopic examination has increasingly become a routine examination method for gastrointestinal diseases, making more and more early tumors of the gastrointestinal tract discovered, and endoscopic treatment also follows The increase will lead to a corres...

AI Technical Summary

Problems solved by technology

Surgical suturing techniques can achieve full-thickness alimentary canal wall suturing, which is an important factor for tissue healing and preventing postoperative leakage of the digestive tract, which is difficult to achieve with the above-mentioned suturing techniques.

When suturing with the help of a digestive endoscope, due to the limited space of the clamp channel of the digestive endoscope, the diameter of the clamp channel of the gastroscope is about 2.8 mm, the diameter of the clamp channel of the colonoscope is about 3.2 mm, and the length of the clamp channel itself is 1.2 mm. ~1.4mm, in such a long and narrow space, the surgical instruments that can be placed are very limited, and the current conventional suturing surgical instruments can no longer meet these requirements, and it is necessary to produce a special instrument for minimally invasive surgery under digestive endoscopy
