Problems solved by technology
[0003] The purpose of the present invention is to provide an endoscopic stapler with an adjustable anvil structure to solve the problem that the anvil assembly of the existing endoscopic stapler proposed in the above background technology is usually integrally formed and cannot be adjusted. However, it is inconvenient to apply the medicine manually, and the body of the stapler and the anastomotic components are prone to loosening or falling off during use, which increases the risk of surgery. The problem

The invention discloses an endoscopic stapler with an adjustable nail anvil structure, comprising a stapler body, an adjustment component, a mounting sleeve and an auxiliary fixing component. The two ends of the bottom of the stapler body are respectively fixed with a handle and a grip The first bolt is arranged on the outside of the mounting frame, the mounting sleeve is fixed under the movable sleeve, and the inside of the mounting sleeve is provided with a syringe, and the firing rod and the outside of the assembly rod are respectively sleeved with A clamp, a sliding block is slidably connected to the surface of the fixing plate. The endoscopic stapler mounting frame and movable plate of the adjustable nail anvil structure are driven by rotating the first bolt outside the mounting frame to drive the movable plate to slide, so that the movable plate can drive the limit block through the inclined surface of the surface and the movable plate. The L-shaped movable block slides toward or away from each other, so that the L-shaped movable block drives the two groups of nail anvils to move toward or away from each other to adjust the distance between them, so as to be adjusted according to the usage conditions and improve its functionality.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an endoscopic stapler with an adjustable nail anvil structure. Background technique [0002] Laparoscopic stapler is one of the important instruments for endoscopic surgery. It is an alternative to traditional manual suturing. It uses titanium nails to cut off or anastomose tissue. It has the advantages of simple and rapid operation, and greatly shortens the operation time. The stapler makes the anastomosis easy, accurate, firm and reliable, which is difficult to perform manual operation with narrow operating field and deep parts, and significantly reduces the incidence of anastomotic leakage. The staple anvil assembly of the existing endoscopic stapler is usually formed in one piece. It is not adjustable, resulting in the uncontrollable gap between the tissues on both sides after suturing, which will cause certain limitations in use, and most of the existing endoscopic...
