Abstract

The invention relates to a percutaneous puncture biliary tract drainage tube of an adjustable locking system, and belongs to the technical field of medical instruments. The drainage tube consists of a drainage tube body, a tube seat and an adjustable locking system, wherein the front end of the adjustable locking system is fixedly connected and communicated with the tail end of the drainage tube body through the tube seat; the adjustable locking system is composed of a locking line, a pressing plate, a torsional spring, a locking system base, a conical sealing plug, a first rotating shaft, a second rotating shaft and a supporting rod; and a drainage inner cavity with the two opened ends is formed in the locking system base. The percutaneous puncture biliary tract drainage tube has the advantages that the locking line can be repeatedly adjusted through the pressing plate, the locking line can be adjusted by pressing the pressing plate, locking can be achieved by loosening, the problem that adjustment is not easy after locking is solved, and the surgical operation difficulty is reduced; the conical sealing plug enables a human body to be completely sealed with the outside, and secondary infection caused by air leakage and liquid leakage is effectively avoided; a supporting rod can effectively fix the pressing plate to enhance the locking effect, and complications such as displacement and slippage caused by looseness of the locking line are prevented.

Description

technical field [0001] The invention relates to a percutaneous puncture biliary drainage tube with an adjustable locking system, belonging to the technical field of medical devices. Background technique [0002] Percutaneous puncture biliary drainage tube is a medical device that is inserted percutaneously into the bile duct, gallbladder, etc. through puncture under the guidance of imaging equipment (ultrasound, CT, DSA, etc.) for bile drainage or cavity perfusion irrigation. Because of its smooth and soft surface, good biocompatibility, and multiple drainage side holes, it is widely used in clinical practice. [0003] The percutaneous puncture biliary drainage tube consists of a tube base, a drainage tube body, and a locking system. The tip of the drainage tube body is generally curled into a pigtail shape, which is used to fix the inner cavity and prevent catheter displacement and slippage; the drainage tube body is soft and smooth, and has a good X-ray imaging effect, wi...
