Biliary tract drainage tube with drainage inner tube

Abstract

The invention provides a biliary tract drainage tube with a drainage inner tube. The tube body of the biliary tract drainage tube is provided with a transparent inner tube which can be movably pulled and inserted; and multiple drainage holes are distributed around the tip of the tube body of the biliary tract drainage tube. When in use, the transparent inner tube can be inserted into the tube body of the biliary tract drainage tube and is guided into the biliary tract along with the tube body; in the guiding process, the drainage condition can be controlled through the transparent inner tube, and a guide support effect can be realized on the tube body; and after normal drainage, the inner tube is pulled out.

Description

technical field [0001] The invention relates to a medical bile duct drainage tube, in particular to a bile duct drainage tube equipped with a fluid guiding inner tube. Background technique [0002] In order to reduce the pressure of the biliary tract and promote the formation of the sinus tract, the hospital needs to indwell a biliary drainage tube in the biliary tract to drain the bile sweat after the open biliary tract exploration operation for the patient. Since the fibrous connective tissue of the sinus tract begins to form, the sinus tract is narrowed and curved to allow drainage It is very difficult to introduce the tube, and the edema of the sinus mucosa will be caused after the biliary tract examination by the choledochoscope. The traditional biliary drainage tube cannot meet the safe and normal use of the current medical treatment. Contents of the invention [0003] The purpose of the present invention is to solve the problems related to the use of the above-menti...
