The invention provides a medical percutaneous transhepatic cholangial drainage (PTCD) catheter, relates to the technical field of medical supplies, and solves the technical problem that most patientscannot accept the requirements that the patients need to take bile orally in PTCD external drainage in the prior art. The device comprises a drainage catheter, wherein the side part of the drainage catheter is provided with a plurality of drainage holes; a balloon is positioned between a liquid inlet hole and a liquid outlet hole; the drainage catheter can be inserted into a biliary tract; and theliquid inlet hole and the liquid outlet hole are respectively positioned at two sides of a narrow section or an occluded section of the biliary tract, so that bile in the biliary tract can sequentially pass through the liquid inlet hole, the inside of the drainage catheter and the liquid outlet hole to realize in-vivo drainage. The medical PTCD catheter is used for percutaneous transhepatic cholangial drainage.
Description
technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medical PTCD catheter. Background technique [0002] The biliary tract has the function of transporting the bile secreted by the liver to the intestinal tract to promote the absorption of fat, cholesterol and vitamins. In clinical medicine, malignant tumors such as cholangiocarcinoma, liver cancer, pancreatic cancer, and metastatic cancer can cause biliary obstruction, which prevents bile from being naturally discharged into the intestinal tract, seriously affecting the prognosis of patients. [0003] The prior art offers two surgical approaches to address bile delivery problems caused by biliary obstruction. One method is: respectively implanting stents in the patient's bile duct and duodenal papilla, so as to discharge bile into the duodenum. However, implanting stents into the bile duct is difficult, expensive, and easy to cause Cholangitis, the patient suffers a ...
