Description

Technical Field

[0001] This utility model relates to the field of drainage tube technology, specifically to a pancreatic duct support drainage tube used in pancreatic surgery. Background Technology

[0002] The pancreas is a long, narrow gland located transversely on the posterior abdominal wall at the level of the lumbar vertebrae. It is soft in texture and grayish-red in color. The pancreas can be divided into four parts: the head, neck, body, and tail. The pancreatic duct is located within the pancreatic parenchyma and runs along the long axis of the pancreas, from the tail through the body to the head, receiving numerous interlobular ducts along the way. Finally, it merges with the common bile duct within the wall of the descending part of the duodenum to form the ampulla of Vater, which opens into the greater duodenal papilla. Sometimes, a small duct can be seen above the pancreatic duct, called the accessory pancreatic duct, which opens into the lesser duodenal papilla. The pancreas is divided into two parts: the exocrine part and the endocrine part. The exocrine gland consists of acini and ducts. The acini secrete pancreatic juice, and the ducts are the channels through which pancreatic juice is discharged. Pancreatic juice contains sodium bicarbonate, trypsinogen, lipase, amylase, etc. Pancreatic juice is discharged into the duodenum through the pancreatic duct and has the function of digesting proteins, fats, and sugars.

[0003] In pancreatic surgery, pancreatic duct support drainage tubes are required. Although pancreatic surgery has developed for many years, research on pancreatic duct support drainage tubes is limited. In many clinical cases, ventricular drainage tubes are used instead. Furthermore, traditional drainage tubes are relatively soft and prone to blockage under pressure, affecting their usability. Additionally, existing drainage tubes cannot be supported at the tube ends, making them susceptible to blockage from other parts of the body. Therefore, this invention aims to develop a pancreatic duct support drainage tube for use in pancreatic surgery. Utility Model Content
