Intraperitoneal Y-T type hepatic duct-duodenum biliary tract external drainage tube

Abstract

The invention discloses an intraperitoneal Y-T type hepatic duct-duodenum biliary tract external drainage tube. The drainage tube is composed of a Y-type drainage tube with a Y-type structure and a T-type drainage tube arranged on the Y-type drainage tube, wherein the top end of the Y-type drainage tube is divided into a left shunt tube and a right shunt tube; the left shunt tube is inserted into the left intrahepatic tube of a human body while the right shunt tube is inserted into the right intrahepatic tube of the human body; and a biliary tract duodenum internal drainage tube at the tail end of the Y-type drainage tube is inserted into the duodenum; and a biliary tract external drainage tube is also arranged at a lateral end of the middle part of the Y-type drainage tube. The intraperitoneal Y-T type hepatic duct-duodenum biliary tract external drainage tube disclosed by the invention is novel in design, easy to operate and reliable in work; meanwhile, since the tail end of the Y-type drainage tube is inserted into the duodenum, the intrahepatic bile can be drained to the duodenum through the Y-type tube so as to assist intra-intestinal food digestion; and the T-type drainage tube is arranged outside the human body, thus decompression drainage and support can be realized, the biliary tract healing is facilitated, and the bile conditions and post-operation cholangiography are convenient to observe.

Description

technical field [0001] The invention relates to a drainage tube, in particular to an intraperitoneal Y-T type hepatic bile duct-duodenal bile duct external drainage tube, which belongs to the technical field of medical devices. Background technique [0002] Generally speaking, the biliary system has the functions of secreting, storing, concentrating and transporting bile, and plays an important role in regulating the discharge of bile into the duodenum; however, cholangiocarcinoma, liver cancer, pancreatic cancer caused by various reasons in real life and metastatic cancer and other malignant internal tumors (malignant biliary obstruction caused by it has been relatively frequent, and the incidence of malignant biliary obstruction is relatively high, and it is often discovered at an advanced stage. [0003] Implanting biliary ducts into strictures or obstructions is currently a better way to treat biliary obstruction, but in complex biliary reconstruction, the application of...

Problems solved by technology

[0003] Implanting biliary ducts into strictures or obstructions is currently a better way to treat biliary obstruction, but in complex biliary reconstruction, the application of biliary ducts is still not optimistic, especially in the case of unsatisfactory biliary reconstruction. At the same time, for patients with bile duct obstruction who cannot undergo surgery, although the current routine practice is to place drainage tubes in the abdominal cavity of the human body, it is no longer possible to directly place drainage tubes for patients with total bile duct obstruction and unresectable surgery. Adopt this conventional method of placing the existing drainage tube in the abdominal cavity of the human body, but in clinical practice, external drainage of PTCD must be performed, but after external drainage, the loss of bile can lead to poor digestive function of the patient, electrolyte Disorder, decreased quality of life
