Disposable medical digestive tube multi-faceted three-dimensional cutting stapler

Abstract

A digestive tract anastomat takes active impelling action in rebuilding a digestive tract, but also has shortages. It is reported that 0.78% of anastomats have mechanical failure, with difficulty in taking out a nail anvil as one reason; and stricture of anastomotic stoma appears after operation by 1.9-9% of round anastomats. At present, esophagus-stomach side-to-side semiopen anastomosis is the better scheme for preventing anastomotic stricture, but chances for pollution are increased. The invention provides a disposable medical multi-surface cutting variable anastomat for the digestive tract, which can be generally used for rebuilding an upper digestive tract, a middle digestive tract and a lower digestive tract and has high shaping degree of anastomosis nails. The anastomat provided by the invention consists of an end side nail anvil, an end side nail bin, an end face half-ring cutting knife, a side ''middle-buckling symmetrical two-scimitar'' shaped cutting knife, a multi-curve shim, a traditional system, an operating handle, an extrusion stroke adjusting system and a mechanical safety lock system. According to the disposable medical multi-surface three-dimensional cutting anastomat for the digestive tract, peripheral diameter of the anastomotic stoma can be effectively expanded to 113mm, so as to eliminate the stricture of the anastomotic stoma after the operation and reduce mechanical failure in clinical application of the anastomat, therefore, the use safety of the operative instrument is improved.

Description

technical field [0001] The invention relates to a disposable medical digestive tube multi-face cutting stapler. Background technique [0002] The disposable digestive canal stapler greatly improves the operation speed, shortens the operation time, and improves the success rate of digestive tract reconstruction and anastomosis. Lin Jianqing of Fujian Medical University and others reported that 0.78% of the staplers still had mechanical failures, and one of the reasons was the difficulty in taking out the anvil. ;The stenosis rate of esophagogastric anastomosis has been significantly reduced by the stapler, but it is still 1.9% -9% The stenosis of the anastomotic stoma after circular stapler operation is mainly due to the small anastomotic caliber. Re-investment in medical treatment is required, which has caused physical, psychological and economic impacts on patients. At present, semi-open anastomosis on the side of esophagus and stomach is the best way to prevent anas...

Problems solved by technology

[0003] At present, the existing staplers are all single-stroke, single-plane staplers, and there is no stapler that can perform multi-stroke multiple-plane three-dimensional cutting
