Problems solved by technology

[0003] It has been reported that a stent was placed in the pancreatic duct at the pancreaticojejunostomy (internal drainage method). Although this method solved the obstruction of pancreatic juice excretion, it did not solve the problem of pancreatic juice stagnating at the pancreaticojejunostomy before the recovery of postoperative bowel motility. In the jejunum, factors that increase the tension of the anastomosis and affect the healing after anastomosis, such as Chinese patent application number: CN98220754.9, publication number: CN2322639Y, invention name: Y-type pancreaticobiliary drainage tube
[0004] Another example is the Chinese Patent Application No.: CN98220697.6, Publication No.: CN2320273Y, Invention Name: "Ten" shaped pancreaticobiliary drainage tube, although this drainage tube solves the problem of the continuous loss of pancreatic juice and bile after the recovery of postoperative intestinal peristalsis and the impact on digestion and absorption functions and The impact of anastomotic healing can prevent the occurrence of anastomotic leakage; however, the pancreatic duct arm of the drainage tube is fixed, and the position cannot be adjusted according to the individual patient. Good support and fixation, and the drainage tube is easy to slip out of the intestine, resulting in intestinal fistula
[0005] At present, there is an urgent need for a pancreaticobiliary support decompression jejunostomy tube that solves the problems of pancreatic juice and bile drainage and anastomotic support after pancreaticoduodenectomy, and solves the impact of pancreatic juice and bile accumulation on anastomotic healing before postoperative intestinal motility is not restored.

Embodiment 1

[0025] A biliary-pancreatic support drainage jejunostomy decompression tube, which is composed of a porous pancreatic duct support drainage arm 3, two porous bile duct support drainage arms 1, 2 and a porous jejunostomy decompression tube 4; two porous bile duct support drainage The arms 1 and 2 are joined together in a "Y" shape; the porous jejunostomy decompression tube 4 is vertically connected to the confluence of the two porous bile duct support and drainage arms 1 and 2; the porous jejunostomy decompression tube has two sides The hole 5, the porous pancreatic duct supporting drainage arm 3 extends into the porous jejunostomy decompression tube 4 through the side hole 5;

[0026] The angle between the two porous bile duct supporting drainage arms 1 and 2 is 45 degrees.

Embodiment 2

[0028] The diameter of the porous jejunostomy decompression tube 4 is 1 cm, the diameter of the porous pancreatic duct support drainage arm 3 is 0.2 cm, the length of the porous pancreatic duct support drainage arm is 36 cm, and the diameter of the porous bile duct support drainage arms 1 and 2 is 0.5 cm , the length is 5cm.

[0029] The inner diameter of the mushroom head expansion part 6 in the middle section of the porous jejunostomy decompression tube is 2 cm, the distance between the middle section expansion part and the confluence of the two porous bile duct support drainage arms is 15 cm, and the diameter of the side hole of the porous jejunostomy decompression tube is 0.2 cm.

[0030] The porous bile duct support drainage arm, the porous pancreatic duct support drainage arm, the confluence of the porous bile duct support drainage arm to the porous jejunostomy decompression tube mushroom head expansion part is made of materials that can be degraded in the human body for ...

Embodiment 3

[0032] refer to figure 2 As shown, after pancreaticoduodenectomy, the porous pancreatic duct support drainage arm 3 is inserted into the pancreatic duct 7 for about 8 cm, and the pancreatic duct is sutured with absorbable suture and fixed firmly. The conventional pancreatic stump is anastomosed with the jejunum 8, and the porous pancreatic duct support drainage arm 3 is about 4 cm away from the pancreaticojejunostomy to lead out the jejunum, and is inserted into the appropriate porous jejunostomy decompression tube side hole 5 according to the individual patient to support the porous bile duct Drainage arms 1 and 2; the porous jejunostomy decompression tube 4 is inserted into the jejunum 8, and a hole is poked at a distance of 8 cm from the pancreaticojejunostomy to lead out the jejunum. Fix the common hepatic duct with intermittent sutures, then suture the jejunum 8 and the surrounding tissues of the common hepatic duct intermittently, and suture the porous jejunostomy decom...

Abstract

The invention discloses a fistulization decompression tube for biliopancreatic supporting drainage jejunum. The tube is formed by a porous pancreiatic duct supporting drainage arm, two porous biliary duct supporting drainage arms and a porous jejunum fistulization decompression tube, wherein the two porous biliary duct supporting drainage arms are connected together in a Y shape; connection parts between the porous jejunum fistulization decompression tube are vertically connected with each other; a plurality of side holes are formed in the porous jejunum fistulization decompression tube; the porous pancreiatic duct supporting drainage arm extends into the porous jejunum fistulization decompression tube via the side holes; the middle section of the porous jejunum fistulization decompression tube is provided with a mushroom head-shaped expanding part; bile drainage can be facilitated by the left and right biliary duct supporting drainage arms; the pancreiatic duct position can be adjusted via different side holes based on individual differences of patients; the expansion design of the middle section of the jejunum fistulization decompression tube prevents fistulization postoperative complications due to duct leakage; the interior of the biliopancreatic drainage tube is evenly made from degradable material, so possibilities of infection, stone and obstruction due to long term arrangement can be reduced; and secondary operation is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a three-in-one multipurpose biliopancreatic support drainage jejunostomy decompression tube used for decompression of pancreatico-biliary support drainage jejunostomy after pancreaticoduodenectomy. Background technique [0002] Pancreatic fistula and biliary fistula are the most common and serious complications after pancreaticoduodenectomy, the incidence rate is 5-25%, and the mortality rate is as high as 80%. The most common causes of biliary tract infection, biliary tract stones, pancreatic duct obstruction, and pancreatic atrophy after resection. To prevent pancreatic fistula, biliary fistula, and biliopancreatic anastomotic stricture, there are more than 20 ways to reconstruct the pancreas and digestive tract. How to prevent pancreatic fistula, biliary fistula, and anastomotic stenosis In addition to the continuous improvement of pancreaticojejunostomy methods, the drainage of...
