Antiskid duetus pancreaticus drainage tube

The utility model relates to the technical field of medical instruments, in particular to an anti-slippage drainage tube for draining pancreatic juice outside the body after pancreas operation. The anti-slippage drainage tube consists of a catheter (1) and a water injection balloon (2), wherein the catheter includes a head section (11), a body section (12) and a tail section (13); the head section (11) thinner than the body section and the tail section has an outer diameter matched with the inner diameter of a pancreatic catheter, and is provided with side holes (111) on the wall thereof; an anti-slippage screw thread (121) is arranged on the wall of the body sector close to the tail end; the water injection balloon (2) consists of a balloon (21), a water injection pipe (22) and a water injection valve (23); one end of the water injection valve is dissociated from the tail end of the catheter to form a Y-shaped branch with the tail end of the catheter; and the balloon (21) and the water injection pipe (22) are attached to the outer wall of the body section of the catheter (12). The anti-slippage drainage tube has the advantages of simple structure and convenient use, and can effectively solve the slippage and leakage problem of the drainage tube, thereby improving the operation success rate and the operation quality.
