Problems solved by technology
The unsatisfactory part of the nail anvil processing method with the staple forming groove of this surgical stapler is that, because the staple forming groove is a blind hole structure, it is difficult to adopt the method of laser, electric spark or ion beam on the stainless steel Smooth staple forming grooves are processed on the anvil, and smooth staple forming grooves play an important role in the formation of staples, and there are dozens or even hundreds of staple forming grooves on the anvil of each surgical stapler , so that the processing efficiency of the nail anvil with the staple forming groove of this style of surgical stapler is low, the quality is poor, and the cost is high

Abstract
The invention relates to a nail anvil processing method of a surgical suturing machine with a suturing nail forming slot. a combined processing method of nonferrous alloy die-casting and electroplate is adopted, or the nail anvil frame and the nail anvil rod of the surgical suturing machine as an insertion part is cast into a whole together with the nail anvil, or a combined processing method of non-ferrous alloy cold stamping and the electroplate is adopted, to realize that solid, accurate, surface smooth, various shapes of suturing nail forming slots can be conveniently processed on the non-ferrous alloy nail anvil die casting or the softer non-ferrous alloy nail anvil base body of a surgical suturing machine, the purposes of higher processing efficiency, better quality and lower cost are reached.
Description
technical field [0001] The present invention relates to the nail anvil processing method with the staple forming groove of the surgical stapler, in particular to the circular stapler, the linear stapler, the linear cutting stapler and the laparoscopic surgical stapler with the staple forming groove Anvil processing method. Background technique [0002] Various surgical staplers and endoscopic surgical staplers are used to replace the manual suture operation with needles and threads in surgical operations. They are being widely used in surgical operations to suture human digestive tract organs, respiratory tract organs and urogenital organs, which can reduce operation time and improve Surgical quality. They are commonly used in end-to-end, end-to-side, and side-to-side suturing operations such as the esophagus, stomach, duodenum, small intestine, colon, and rectum in the digestive tract or hemorrhoidectomy to form passages and to close incisions. Suture operations such as l...
