[0002] Deep spinal infection is one of the serious diseases in humans, which requires thorough debridement, flushing and drainage of pus and inflammatory substances. Continuous closed flushing and drainage has achieved significant therapeutic effects in clinical treatment.

[0003] However, during the treatment process, it is necessary to use an irrigation tube for irrigation and a drainage tube for drainage at the same time, which not only makes irrigation and drainage inconvenient, but also makes the wound larger, increasing the patient's pain. At the same time, during drainage, blood clots, dead bones, muscle soft tissue or hyperplastic soft tissue in the lesion will block the drainage tube, causing the irrigation fluid to accumulate in the patient's body, increasing local edema, pain, and even soft tissue necrosis. In the past, the method to solve the blockage was mainly to use a thick closed chest drainage tube, adjust the insertion depth and direction of the drainage tube, and rotate the drainage tube to make the drainage hole avoid the obstruction. This operation will increase the patient's pain. In addition, during drainage, some hyperplastic soft tissue will adhere to the infected area, affecting the efficiency and effectiveness of irrigation and drainage. Summary of the invention

[0030] The outer tube 17 and the annular cover 11 are detachably connected via threads, so that the outer tube 17 can be easily disassembled.

[0031] Working principle: When in use, during flushing and drainage, the outer tube 17 and the annular cover 11 are inserted into the drainage part, and then the external flushing liquid is supplied into the annular cover 11 through the flushing tube 13, and flows out through the flushing hole 12 to flush the infected part, and the flushing liquid and soft tissue after flushing can be drained out through the inner tube 16 and the drainage tube body 1, so that flushing and drainage can be combined, which is more convenient to use and has better effect. At the same time, when the flushing liquid enters the annular cover 11 through the flushing tube 13, it will impact on the surface of the blade 502, so that the rotating disk 501 rotates. When the rotating disk 501 rotates, the rubber wheel 302 is driven to rotate through the rotating shaft 301, and then the rotating ring 14 and the blade 15 are driven to rotate, so that larger soft tissues can be chopped to avoid blockage, so that the flushing and drainage are more efficient and effective. At the same time, when flushing and drainage are performed, when the rotating ring 14 rotates, the rubber rod 402 is driven to rotate through the fixed rod 401, so that the infected part can be cleaned, and the soft tissue adhering to the infected part is easy to separate, so that the flushing and drainage efficiency is higher and the effect is better; Furthermore, when the rotating ring 14 rotates, the inner tube 16 is driven to rotate synchronously, thereby driving the synchronous rotation of the fixed ring 201, the fixed rod 401 and the extrusion block 204. When the moving block 702 abuts against the inclined surface 802, the moving block 702 and the moving rod 701 can be pushed to move away from the pushing block 801. At the same time, the extrusion block 204 is driven to move along the strip opening 203 into the inner tube 16. Moreover, the spring 703 is compressed. When the moving block 702 passes over the pushing block 801, the extrusion block 204 can move and reset along the strip opening 203 toward the pushing block 801. In this way, the extrusion block 204 can reciprocate, thereby squeezing and crushing the soft tissue in the drainage fluid to avoid blockage, thereby ensuring the efficiency and effect of flushing and drainage. After use, the outer tube 17, the drainage tube body 1 and the flushing tube 13 can be disassembled and replaced, and the annular cover 11 etc. can be cleaned and disinfected before reuse.
