Abstract
The invention discloses an application of an endoscopic continuous suturing device in preparation of stomach folding suturing medical instruments, the endoscopic continuous suturing device comprises a suture line with uniformly distributed barbs, a plurality of titanium clips and a pushing device, the length of the suture line is 6-10cm, the two ends of the suture line are respectively provided with a front end connecting ring and a rear end connecting ring, a leather sleeve is arranged at the position, close to the rear end connecting ring, of the suture line, and the pushing device is connected with the front end connecting ring and the rear end connecting ring. The titanium clip is used for clamping and fixing gastric mucosa tissue and a suture line, the pushing device is used for tightening the suture line and comprises a traction steel wire, an inner pushing tube and an outer sheath tube which are slidably sleeved from inside to outside, a metal hook is arranged at the front end of the traction steel wire, and two operating handles are arranged at the rear end of the pushing device and used for controlling the inner pushing tube and the traction steel wire to move front and back respectively. Gastric mucosa is sutured through the barb suture line, long-term stability of stomach wall folding is ensured, step-by-step pre-tightening can be achieved by matching the barb suture line with the titanium clamp, and the gastral cavity volume is allowed to be accurately controlled.
