Memory alloy suturing nail and suturing device

Abstract

The invention discloses a memory alloy suturing nail which comprises a nail beam and two nail legs, wherein the two nail legs are respectively in same-direction connection with the two ends of the nail beam; the memory shape of the suturing nail is a B shape, O shape or C shape; the invention further discloses a suturing device suitable for the memory alloy suturing nail. By adopting the memory alloy suturing nail and the suturing device, suturing and fixing operation of tissue or an implant can be rapidly completed through an endoscope, the operation is simple, stimulation for peripheral tissue is less and suturing and fixing effects are good.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a memory alloy staple and a stapler. Background technique [0002] Minimally invasive surgery is increasingly used clinically because of its small surgical wound, less blood loss, and faster recovery of patients. However, minimally invasive surgery needs to complete a series of complicated surgical operations in a narrow surgical space with the help of various surgical instruments, which puts forward higher requirements for surgeons, and there is an urgent need to develop instruments suitable for minimally invasive surgery. . [0003] Laparoscopic surgery is the most common clinical minimally invasive surgery. In various laparoscopic surgeries, corresponding tubular staplers have been developed for tubular organs, such as the gastrointestinal tract, trachea, and esophagus; linear staplers have been developed for lungs, liver, etc. . However, such as the fixation of various patch...

AI Technical Summary

Problems solved by technology

However, such as the fixation of various patches and the fixation of peritoneum after surgical separation, the commonly used suture techniques still use traditional needle and thread suture. However, due to the poor field of view under the laparoscope, the operation space is small, the operation distance is long, and suture is difficult and expensive. Frequently asked questions by surgeons

In clinical practice, there is a kind of helical screw used for suturing and fixing patches or tissues, but after the suturing and fixing of this helical nail, the nail cap protrudes obviously outside the tissue, which may cause irritation and discomfort to the surrounding tissue, especially as The intestinal tract is a constantly peristaltic organ, and if the screw screw is caused to rotate in reverse, it may cause the screw screw to loosen and fall off
