Abstract

The invention provides an eversion type annular anastomat with a fixing device. The eversion type annular anastomat comprises a nail anvil part, a nail bin part and a fixing part, wherein the nail anvil part comprises a left nail anvil and a right nail anvil which can be separated, and the left nail anvil is rotatably connected with the right nail anvil; the nail bin part comprises a left nail binand a right nail bin which can be separated, and the left nail bin and the right nail bin are connected in a rotating mode; the fixing part comprises a fixing device used for fixing everted tissue onthe outer surface of the nail anvil part, puncture needles are arranged on the fixing device, and the fixing device is fixed on the outer surface of the nail anvil part through the puncture needles.According to the technical scheme, the ectropion tissue can be conveniently fixed to the outer wall of the anastomat, the two problems that the tissue is disengaged and fixed after suturing are solvedon the instrument, the eversion type annular anastomat has the advantages that the ectropion intestinal canal tissue does not need to be packed and is directly fixed to the instrument through the fixing device, instruments are convenient to open after an operation is finished, and the fixing method is easy to implement and good in operability.

Description

technical field [0001] The invention relates to the field of medical instruments, further to the field of digestive tract staplers, in particular to an eversion-type circular stapler with a fixing device. Background technique [0002] Stapler is a device widely used in medicine to replace manual suturing. The main working principle is to use titanium nails to cut and anastomose tissues. It is especially suitable for some hollow organs, such as esophagus, stomach, small intestine, large intestine, rectum, etc. Surgery, these parts of the surgery will use staplers. [0003] At present, linear cutting stapler and circular stapler are mainly used in the operation. A section of long tube is provided on the body of the two to facilitate insertion into the human body, and circular sutures for cavity tissues such as the esophagus and small intestine are generally used. A circular stapler will be used. When a circular stapler is used for anastomosis of luminal tissue, one end of the...
