Embodiment

[0017] Such as figure 1 Shown, a digestive tract connector for digestive tract reconstruction in duodenectomy, a digestive tract connector for digestive tract reconstruction in duodenectomy, for use in duodenectomy When reconstructing the middle gastrointestinal tract, the pancreas, common bile duct, stomach and jejunum are anastomosed.

[0018] The digestive tract connector includes a connector body 1. The shape of the connector body 1 is tubular. One end of the connector body 1 is larger and the other end is smaller. The larger end of the connector body 1 is used to anastomose with the stomach of the human body. The connector body 1 The smaller end is used for anastomosis with the jejunum of the human body.

[0019] A bile duct anastomotic tube 2 and a pancreatic anastomotic tube 3 are provided on the side wall of the connector main body 1, one end of the bile duct anastomotic tube 2 communicates with the connector main body 1, and the other end is used for anastomosis wit...

Abstract

The invention discloses a digestive tract connector for reconstructing a digestive tract in duodenectomy. The digestive tract connector is used for anastomosing of a pancreatic gland, a common bile duct, a stomach and an empty intestine when the digestive tract is reconstructed in the duodenectomy, and comprises a connector main body, wherein the connector main body has a pipe-shaped appearance; one end of the connector main body is relatively large and the other end of the connector main body is relatively small; the relatively large end of the connector main body is anastomosed with the stomach of a human body; the relatively small end of the connector main body is anastomosed with the empty intestine of the human body; a bile duct anastomosing tube and a pancreatic gland anastomosing tube are arranged on a side wall of the connector main body; one end of the bile duct anastomosing tube is communicated with the connector main body and the other end of the bile duct anastomosing tube is anastomosed with the bile duct of the human body. One end of the pancreatic gland anastomosing tube is communicated with the connector main body and the other end of the pancreatic gland anastomosing tube is anastomosed with the pancreatic gland of the human body. According to the digestive tract connector disclosed by the invention, the anastomosing of the pancreatic gland, the common bile duct, the stomach and the empty intestine can be rapidly finished, the surgery time is shortened and injuries to patients in surgeries are reduced.

Description

technical field [0001] The invention relates to the technical field of auxiliary instruments for duodenectomy, in particular to a digestive tract connector used for digestive tract reconstruction in duodenectomy. Background technique [0002] Pancreaticoduodenectomy (pancreaticoduodenectomy), also known as Whipple procedure (whipple procedure), is used to treat cancer of the head of the pancreas, cancer of the ampulla of Vater, cancer of the lower segment of the common bile duct, and duodenal cancer around the ampulla. major surgery. [0003] Such as figure 2 As shown, the operation includes en bloc resection of the pancreatic head, distal stomach, duodenum, gallbladder, distal common bile duct, proximal jejunum, and focal lymph nodes, followed by pancreaticojejunostomy, jejunocholangiojejunostomy, and gastrojejunostomy . [0004] Among them, the anastomosis of the pancreas, common bile duct, stomach and jejunum to reconstruct the digestive tract after the operation takes...
