Biliary tract flusher and using method thereof

The invention relates to a biliary tract flusher. The biliary tract flusher comprises a tube body and a bulge. The tube body is used for being inserted into a biliary tract and matched with the biliary tract, the tube body is provided with a head end and a tail end, and through holes are formed in the tube body and used for being located in ductuli hepaticus communis; and an opening is formed in the tail end of the tube body and used for being matched with an infusion joint. The bulge is arranged on the outer surface of the tube body and protrudes in the radial direction of the tube body. Thebiliary tract flusher can be positioned in the biliary tract through a binding strip and the bulge, thus the infusion joint can be connected into the opening in the tail end of the tube body, an infusion container can be hung on an infusion support, the position of the infusion container can be kept stable, thus biliary tract flushing liquid loaded in the infusion container can gradually flow outfrom the infusion container, when the biliary tract flushing liquid flows into an intrahepatic bile duct, the pressure is uniform, and endothelia of the biliary tract are not liable to be injured; andmeanwhile, the biliary tract flusher is positioned in the biliary duct, the position of the biliary tract flusher is stable, thus a biliary duct can be flushed repeatedly, and sufficient flushing isfacilitated.
