Description

Technical Field

[0001] The invention relates to the technical field of shell surgical instruments, in particular to a surgical drainage tube. Background Art

[0002] Surgical drainage tubes are commonly used medical devices in surgical operations. Usually, surgical drainage tubes need to be used in conjunction with collection bottles or drainage bottles to divert the patient's blood or tissue fluid. When the drainage tube is connected to the drainage bottle, it is easy for the drainage tube to loosen or fall off due to pulling, which can easily cause liquid leakage. In addition, the drainage tube is difficult to quickly fix when connected to the puncture site, and there may be a risk of the drainage tube falling off, resulting in the inability to smoothly divert the body's fluid.

[0003] To this end, the Chinese patent with the publication number of "CN221787800U" has published "a surgical drainage tube", the main structure of which includes a tube body, one end of the tube body is fixedly connected to the connecting tube through a connecting plate, the bottom of the connecting tube is fixedly connected to an annular ring that is sleeved with the connecting tube, the surface of the connecting tube is movably sleeved with a connecting mechanism, the movable ring is movably sleeved with the surface of the tube body, one side of the movable ring is fixedly connected to the movable tube, and one end of the movable tube is rotatably connected to a limit rod. The surgical drainage tube adopts a tube body to achieve the diversion of the body fluid, and a connecting tube and a connecting mechanism are arranged at one end of the tube body, which can realize the rapid fixation of the tube body, and the rapid connection can be achieved by adopting the cooperation of the positioning block and the positioning groove. At the same time, the sealing of the connection between the connecting tube and the sleeve is achieved by setting an annular ring, which improves the connection convenience and stability, and the movable ring can be moved on the tube body to adjust the fixed position by setting the movable ring, and the movable ring is limited by setting the limit rod, so that it drives the patch to fit the skin of the drainage tube and the puncture position to achieve the protection of the puncture position.
