Abstract

The invention relates to a pancreiatic duct jejunum anastomat which comprises an anastomosis nail, a nail seat, an anastomosis nail brake forming mechanism and a nail seat feed mechanism. The anastomosis nail comprises a first rod piece, a second rod piece, a third rod piece and a fourth rod piece. The length direction of the first rod piece is parallel to the pushing direction of the nail seat feed mechanism. The anastomosis nail is arranged in the nail set. The third rod piece is disposed on one side of the anastomosis nail brake forming mechanism in the pushing direction. The nail seat is disposed on one side of the nail seat feed mechanism in the pushing direction. The nail pushing mechanism can push the nail seat and the anastomosis nail on the nail seat to move forwards. The anastomosis nail brake forming mechanism can push the third rod piece to buckle around a joint point of the third rod piece and the second rod piece in the direction of the first rod piece until an included angle between the third rod piece and the second rod piece become a right angle. By the pancreiatic duct jejunum anastomat, the problems of high operation precision requirements and operation difficulties of pancreiatic duct jejunum operations with prior arts can be solved. The pancreiatic duct jejunum anastomat can be used in not only normal laparotomy surgeries but also laparoscopic surgeries by means of extended components.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pancreaticojejunal stapler. Background technique [0002] Pancreaticojejunostomy is one of the most difficult operations in pancreatic surgery. The operation requires anastomosis between the human small intestine and the section of the pancreas, so that the pancreatic juice can flow into the small intestine and exert its unique digestive function. Under normal circumstances, the diameter of the human pancreatic duct is about 4-5mm. Even in a diseased state, the widest pancreatic duct is not more than 8-10mm. It is quite technically difficult to anastomose the pancreatic duct and requires a long time of training. Completion of a qualified anastomosis. The existing patents for pancreaticojejunostomy are based on the principle of bundled pancreaticojejunostomy, that is, the intestinal tube is directly inserted into the stump of the pancreas and then fixed. This bundled anastomosis...
