Embodiment Construction

[0016] figure 1 The structure of the gastric wall puncture needle of the present invention is shown, including a suture 1 and two gastric wall puncture needles 2, 3, and the two ends of the suture 1 are respectively connected to the rear ends of the gastric wall puncture needles 2, 3.

[0017] figure 2 , image 3 and Figure 4 A paracentesis needle is shown, including a needle tube 11 and an operating handle 12 , the needle tube 11 has an inner sheath 13 , and the front end of the inner sheath 13 has a needle sheath 14 and a needle groove 15 . The needle sheath 14 is in the shape of a circular tube, so as to fix the gastric wall puncture needle 2 and expose the front end of the gastric wall puncture needle 2 above the needle sheath 14 . Needle groove 15 can be put into gastric wall puncture needle 3, and needle groove 15 has notch, so that when the front end of inner sleeve 13 stretches out beyond needle tube 11, the gastric wall puncture needle 3 that is placed in needle ...

Abstract

The invention discloses a device capable of easily and endoscopically suturing and ligating a stomach wall, which comprises a suture line, two stomach wall puncture needles for puncturing the stomach wall, an abdominal cavity puncture needle for puncturing an abdominal cavity, a knotter and a pair of ligature forceps. By puncturing of the abdominal cavity and the stomach wall, both ends of the suture line respectively pass through both sides of a wound of the stomach wall from the outside of the stomach wall; and the suture line is knotted in the stomach to complete suturing and ligating the stomach wall, so that endoscopic suture and ligation of the stomach wall are implemented and implementation of a minimally invasive surgery is ensured. With the adoption of the device, suturing operation is easier to carry out; pain of a patient can be greatly relieved; and the area of the wound of the patient is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for suturing and ligating the stomach wall under an endoscope. Background technique [0002] With the increasing development of endoscopic technology, especially the combined use of endoscope and laparoscope and the development of endoscopic interventional therapy technology, the recently proposed NOTES (natural orifice transluminal endoscopic surgery, natural orifice transluminal endoscopic surgery) has emerged in recent years. surgery), allowing the endoscope to enter the abdominal cavity for various endoscopic operations and surgeries. Due to the obvious minimally invasive effect of NOTES treatment, it has attracted more and more attention from the industry, and a large number of animal experiments and clinical applications have been carried out in many fields of surgery; Biopsy and hepatic cyst fenestration are awaiting experimental and clinical application, and as a result, some...
