[0023] Further, the water inlet pipe 31 and the water outlet pipe 41 are made of polypropylene material.

[0024] Further, the spiral water inlet channel 30 and the inside of the channel tube 10 form a water outlet port 32, the water outlet channel 40 and the inside of the channel tube 10 form a water inlet port 42, the water outlet port 32 and the water inlet port 42 are respectively tangent to the inner wall of the channel tube 10, so that the water flow is better contacted with the inner wall of the channel tube 10, and the water inlet port 42 is larger than the water outlet port 32.

[0025] Further, the bottom of the water outlet channel 40 surrounds at least one-fourth of the channel tube 10, and the water outlet channel 40 is spirally arranged upward.

[0026] Embodiment 2:

[0027] As shown in FIG. 1-2, the spinal minimally invasive surgery flushing suction micro-channel of the embodiment comprises a channel tube 10 and a connecting handle 20, one end of the connecting handle 20 is fixedly connected to the upper part of the outer wall of the channel tube 10, and the other end of the connecting handle 20 is provided with a connecting port 21 for connecting with a snake-shaped arm; the channel tube 10 is further provided with a spiral water inlet channel 30 in the tube body, the spiral water inlet channel 30 is spirally arranged downward, the spiral water inlet channel 30 surrounds the half or more than half of the axis of the channel tube 10, one end of the spiral water inlet channel 30 is communicated with a water inlet device 50 through a water inlet pipe 31, and the other end of the spiral water inlet channel 30 is communicated with the inside of the channel tube 10; the channel tube 10 is further provided with a water outlet channel 40, one end of the water outlet channel 40 is communicated with the inside of the channel tube 10, the other end of the water outlet channel 40 is communicated with a water outlet device 60 through a water outlet pipe 41, the water outlet channel 40 is arranged below the spiral water inlet channel 30, and the spiral water inlet channel 30 is arranged in the tube body close to the top end of the channel tube 10, and the water outlet channel 40 is arranged in the tube body close to the bottom end of the channel tube 10.

[0028] Further, the water inlet pipe 31 and the water outlet pipe 41 are made of polypropylene material.

[0029] Further, the spiral water inlet channel 30 is in communication with the inside of the channel pipe 10 to form a water outlet 32, and the water outlet channel 40 is in communication with the inside of the channel pipe 10 to form a water suction port 42.

The water suction port 42 is larger than the water outlet 32.

[0030] The working principle of the present application is as follows: after the skin is expanded by the puncture needle and the dilatation sleeve, the channel pipe 10 is sleeved outside the dilatation sleeve and inserted into the skin, and then the dilatation sleeve is removed, thereby completing the setting of the present application.

[0031] When blood, residual liquid and the like need to be cleaned, the water inlet device 50 delivers physiological saline into the spiral water inlet channel 30 through the water inlet pipe 31. Since the spiral water inlet channel 30 is spirally arranged, the physiological saline makes circular motion before entering the inner wall of the channel pipe 10, so that the physiological saline forms a vortex after entering the inner wall of the channel pipe 10, thereby flushing the inner wall of the channel pipe 10. Then, the water drainage device 60 starts to work. The water drainage device 60 sucks out the physiological saline that has completed the cleaning task through the water outlet pipe 41 and the water outlet channel 40 at the water suction port 42, thereby completing the cleaning work.

[0032] Since the physiological saline is used for cleaning, a small amount of residual liquid that is not sucked by the water suction port 42 will not affect the human body and the operation process.

[0033] Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
