Problems solved by technology

The biggest disadvantage of this invention is that it uses a metal needle instead of a thread. The size of the circle of the needle and the amount of tissue it pricks may affect the firmness and sealing of the closure. If the circle is large or contains less tissue, it will still The closure is not tight. Once the fistula still exists, all previous efforts will be for naught. Another disadvantage is that when the suture is wrong, there is no special recovery device, so it is difficult to recover. If it is taken by force, it will aggravate further damage to the tissue and may cause massive bleeding. Do not take it. Because it is a metal object, it takes up space and affects the suture of the next stitch, and the work continuity is poor

Abstract

The invention provides an endoscope suture instrument comprising an sheath, a suture needle, a first driving component, a second driving component and a steel wire, wherein the projections of both the sheath and the suture needle are C-shaped, the sheath is provided with an arc-shaped groove fit with the diameter of the suture needle on the inner side, the arc-shaped groove is in contact with the outer side of the suture needle, inner teeth are arranged on the inner side of the suture needle, the first driving component and the second driving component are fixed on the sheath and movement transmission tail end of each of the first and second driving components is engaged with the inner teeth on the suture needle, and the tail end of the steel wire is Y-shaped and divided into two branches respectively connected with the first driving component and the second driving component to serve as power elements of the first driving component and the second driving component. The first driving component and the second driving component drive the suture needle to rotate to one direction in relays; the sheath plays a role in guiding the movement of the suture needle; the steel wire moves to and fro to driving the suture needle to rotate; the endoscope suture instrument is reasonable in structure, and the suture needle is good in continuous suture operability.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscopic stapler. Background technique [0002] The endoscopic stapler is used for suturing the internal operation of the gastrointestinal tract. When in use, the endoscopic stapler enters the gastrointestinal tract of the human body through the endoscope. The Chinese invention patent with the publication number CN105919636A discloses a rotatable stapler-type endoscopic suturing device, which includes a suture needle and a clip. The clip includes an open annular sleeve through which the suture needle can be put into the sleeve. Inside the barrel, the annular sleeve is provided with a fixed base and a movable suture needle baffle for opening and closing the opening. The baffle is connected to the base by a spring, and a pull cord is provided to drive the baffle to move. When the stapler is suturing the wound or tissue, turn the skin on both sides of the wound up ...
