Abstract

The invention provides a 3D-printed sutureless biliary-intestinal anastomosis support for hepatopancreatobiliary surgery and relates to the technical field of surgical anastomosis. The 3D-printed sutureless biliary-intestinal anastomosis support for the hepatopancreatobiliary surgery comprises a connecting bucket rack, wherein symmetric-arranged supporting grooves are separately formed in the twoends of the external wall of the connecting bucket rack, supporting maintaining plates located at supporting groove positions of corresponding positions are fixedly connected with the external wall ofthe connecting bucket rack, two symmetric-arranged adjusting grooves which are located at the two sides of the same horizontal line are formed in the external wall of the connecting bucket rack, positions of the two adjusting grooves are rotatably connected with rotating threaded rods in a penetrated manner, single ends, far away from the adjusting grooves, of the two rotating threaded rods are rotatably connected with the internal wall of the connecting bucket rack, and two symmetric-arranged adjusting fixing heads are arranged in the two adjusting grooves. A biliary-intestinal anastomat support can be sutureless and be thorough in connection, hepatopancreatobiliary ducts can be effectively maintained unblocked, and unblocked blood can be kept.

Description

Technical field [0001] The present invention relates to the technical field of surgical anastomosis, in particular a 3D printing-free sewing gallball induction bracket. Background technique [0002] Traditional ceiling-inspulcated duodenal surgery is complex, surgical wounds, and gallbladder, pancreatic, swappable, is a key step of pancreatic duodenity, due to the gallbladder or (with the pancreatic enemies The gallbladder anastomotic fistula caused by the incomplete healing is not a frequently consistent complications of postoperative, generally 5 ~ 20%, and the mortality rate of the pancreatic anastoma can reach 20 to 40%, and Treatment costs are expensive. At present, the clinical application of gallbladder and penetration, the pancreatic, the best, the ideal, the most ideal basis for the establishment and sewing, knotting. [0003] The way the digestive tract reconstruction is an anastomosis that exempts these operations related to stitching. Sewing naturally has a needle eye...
