Abstract

The invention relates to the field of medical instruments, in particular to a pancreaticojejunostomy device. The device comprises a pancreas fixing part, an intestinal canal fixing part, a pancreatic juice drainage pipe, a drainage pipe fixing part and an adjusting part, wherein the pancreas fixing part and the intestinal canal fixing part are detachably connected through the adjusting part, the pancreas fixing part is arranged on the outer surface of the pancreas in a sleeving mode, the drainage pipe fixing part is fixedly arranged in the middle of the intestinal canal fixing part, the intestinal canal fixing part is arranged in the intestinal canal, and the intestinal canal fixing part abuts against the inner surface of the intestinal canal; the pancreatic juice drainage pipe is arranged at the center of the drainage pipe fixing part in a penetrating mode, and the pancreatic juice drainage pipe makes the interior of the intestinal canal and the interior of the pancreas communicated. The pancreas fixing part and the intestinal canal fixing part are connected and fixed through the adjusting part, and the adjusting part is adjusted to control the pancreas section to be in close contact with the intestinal serosa layer so that the intestinal mucosa can be matched with the pancreas mucosa; the pancreatic juice drainage pipe is fixed through the drainage pipe fixing part, the interior of the intestinal canal is communicated with the interior of the pancreas, and the pancreatic juice is guided into the intestinal canal from the pancreas.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pancreaticojejunal stapler. Background technique [0002] At present, pancreatic cancer is known as the "king of cancers", and its incidence rate is increasing year by year. The effective treatment is pancreaticoduodenectomy, which is also a treatment for pancreatic head tumors, duodenal Intestinal papillary tumors, ampullary tumors, and descending duodenal tumors are the main surgical methods. This is the most important operation in abdominal surgery. The operation requires resection of six viscera in the pancreaticoduodenal region, and three anastomoses of the pancreas-enteriae, biliary-intestine, and gastrointestinal tract. Due to the fragility of pancreatic tissue and the strong corrosive effect of the secreted pancreatic juice, the failure of pancreaticojejunostomy followed by pancreatic fistula has always been a difficult problem for pancreatic surgeons. Pancreaticoje...
