Percutaneous intrahepatic bile duct-ascites shunt synchronous drainage tube

Abstract

The invention discloses a percutaneous intrahepatic bile duct-ascites shunt synchronous drainage tube. The drainage tube comprises a bile tube, the outer portion of the bile tube is sleeved with an ascites tube, two <-shaped branch tubes capable of being deformed by pulling of a pull wire are arranged at one end of the bile tube, the ends, away from the bile tube, of the two branch tubes are connected,and one end of the pull wire penetrates through the bile tube and one of the branch tubes and then penetrates through the bile tube to return to the outside of the drainage tube; a tube body of the ascites tube is provided with more than one compressible and extensible corrugated section, each corrugated section comprises a corrugated section A close to the section A of the bile tube and a corrugated section B close to a pipe opening of the ascites tube, and an ascites drainage opening is formed in the side wall of a corrugated piece of each corrugated section A; and a plurality of biliary drainage openings are formed in the section A of the bile tube and the branch tubes. The drainage tube is simple in structure, firm in fixation and flexible and convenient to use, and can achieve the function of simultaneously draining abdominal dropsy and bile by avoiding wounds caused by multiple punctures.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a synchronous drainage tube for percutaneous intrahepatic bile duct-ascites diversion. Background technique [0002] Intrahepatic bile duct dilatation may occur when the patient suffers from pancreatic head, liver, duodenum and other tumors or other tumors that block the outflow of the bile duct, or acute inflammation of the pancreas, liver, and biliary system, and surgical operations on the digestive system of the hepatobiliary and pancreas , which requires percutaneous placement of intrahepatic bile ducts to drain bile out of the body to prevent cholestasis; and the above conditions are often accompanied by peritoneal effusions: ① cancer patients with advanced dyscrasias with large amounts of peritoneal effusions; ② inflammation stimulates the peritoneum to cause reactions ascites or infected ascites; ③ peritoneal effusion around the operation area after operation. ...

AI Technical Summary

Problems solved by technology

[0003] In the case of perihepatic effusion in patients with percutaneous intrahepatic bile duct drainage tubes, if the ascites is not drained out in time when the bile is being drained, it may lead to (1) mixing of ascites and bile to cause infection; (2) Ascites leaks into the subcutaneous area, which will cause subcutaneous edema at the puncture point and the surroundi
