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...
