Description
Technical Field
The invention relates to the technical field of endoscopic cutting anastomats, in particular to an endoscopic cutting anastomat with an adjustable transmission mechanism.
Background
Staplers are devices used in medicine to replace manual suturing, the main working principle being the detachment or anastomosis of tissue by titanium staples, similar to staplers. The anastomat can be mainly divided into a skin anastomat, a circular anastomat for digestive tracts (esophagus, stomach and intestine and the like), a rectal anastomat, a circular hemorrhoid anastomat, a circumcision anastomat, a blood vessel anastomat, a hernia anastomat, a lung cutting stapler and the like according to different application ranges. Because of safety, reliability, convenience and rapidness, the method is widely applied and popularized in recent years. The suture titanium nail plays an important role as a key part of the anastomat, has very strict requirements on the material, the shape and the size of the suture titanium nail, and has the problems that the production and the manufacture of the suture titanium nail are always a difficult problem for anastomat production enterprises because the suture titanium nail has small volume and precise size requirements and the mouth part of the suture titanium nail needs to be sharp and sharp.
The working principle of the surgical anastomat is generally as follows: the tissue is stapled together by closing two cooperating handle assemblies (typically one handle containing the anvil assembly and the other handle containing the cartridge assembly) to grasp the tissue and then pushing the staples out of the cartridge assembly for formation. In some staplers, a cutting blade is provided to cut the tissue between the rows of staples while the rows of staples are being driven into the body tissue, thereby severing the stapled tissue.
Most anastomat are the gun type under prior art, handle portion and probe into pole mutually perpendicular and fixed, when carrying out patient intracavity tissue cutting suture, on the one hand, handle portion shelters from doctor's sight, and on the other hand, handle portion is difficult to go deep into patient's intracavity, has increased the operation degree of difficulty.
