Background

Currently, with the continuous development of endoscopic technology and the continuous improvement of accessories thereof, the duodenoscopy (ERCP) technology has become an important measure for treating diseases of liver, gallbladder and pancreas, including choledocholithiasis, bile duct injury, bile duct stenosis, biliary tract complications after liver transplantation, and the like. Compared with the traditional laparotomy, the technique has the advantages of small wound, high safety factor, quick recovery and the like. The direct-view observation of the liver, gallbladder, spleen and pancreas can detect the liver, gallbladder and pancreas diseases which can not be detected by the conventional examination of the liver, gallbladder, spleen and pancreas, such as CT, ultrasound, magnetic resonance and the like.

Although the ERCP has the advantages, the bile duct intubation has certain difficulty, and the difficulty of bile duct intubation is increased by atrophy of papilla, diverticular papilla, bile-pancreas confluence abnormity and the like. There are also complications after ERCP surgery, with pancreatitis, cholangitis, and hemorrhage being the three major complications after ERCP surgery. The complications often significantly increase the treatment cost, prolong the hospitalization time, bring great pain to the patients, and have a certain mortality rate. Clinically, biliary intubation is often performed by taking a pancreatic stent out of a patient with difficult intubation, and an intra-pancreatic drainage tube is often placed in a pancreatic duct during operation in order to reduce the incidence of postoperative complications of ERCP.

The pancreatic duct stent clinically applied at present comprises a straight pancreatic duct stent and a single pig tail pancreatic duct stent, and the two pancreatic duct stents have the following defects: 1. after the straight pancreatic duct stent is released, the tail flank of the straight pancreatic duct stent is often in a closed state with different degrees, and the straight pancreatic duct stent is easy to shift into a pancreatic duct under the nipple of the duodenum, so that the pancreatic duct stent is difficult to take out, and the incidence rate of post-operation pancreatitis is increased; 2. after the straight pancreatic duct stent is released, the tail part of the straight pancreatic duct stent is easy to press the wall of the opposite duodenum, so that intestinal spasm is induced, pain in the upper abdomen is caused, and even duodenal perforation is caused.

Therefore, the pancreatic duct internal drainage support with the metering function is provided for solving the problems in the prior art, the pancreatic duct internal drainage support is combined into a pancreatic duct internal drainage pipeline by sequentially passing through the vertical pipe, the transverse pipe and the pipe head, four groups of supporting components are arranged on the tail side of the transverse pipe, and the pancreatic duct support is prevented from being displaced into the pancreatic duct under the nipple of the duodenum, so that the pancreatic duct support is difficult to take out, and the incidence rate of postoperative pancreatitis is reduced.
