[0002] Chinese medicine hook needle is a minimally invasive treatment technology that combines Chinese medicine theory with modern medical knowledge. It uses a special hook needle to treat specific acupuncture points on the human body through aseptic operation to achieve the purpose of relieving pain, improving function and promoting recovery. The hook needle technique is usually used to treat spinal degenerative diseases, osteoarthritis, soft tissue degenerative diseases, etc.

[0003] The existing disposable crochet hooks are stored in disposable sealed bags. When they are needed, the sealed bags are torn off to expose the handles for use. As a result, each crochet hook needs to be equipped with a handle for easy holding. The handles will be thrown away together with the crochet hooks after use, which causes waste. In addition, the protection of the disposable crochet hooks by the sealed bags is easily damaged, which can easily cause the crochet hooks to be contaminated. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 7 As shown, the disposable crochet needle of the present invention comprises a cylinder 1, a crochet needle assembly 2 is arranged at the upper end of the cylinder 1, an adjustment assembly 3 is arranged at the lower end of the cylinder 1, and a disinfection assembly 4 is arranged at the upper end of the crochet needle assembly 2; The hook assembly 2 includes a plurality of arc blocks 21, which are clamped on the top of the cylinder 1, and the lower ends of the plurality of arc blocks 21 are clamped with the same annular groove 22, which is opened at the upper end of the cylinder 1, and the inner walls of the lower ends of the plurality of arc blocks 21 are provided with grooves 23, and the upper ends of the plurality of arc blocks 21 are fixedly connected with replacement hooks 24, and the inner walls of the bottoms of the plurality of grooves 23 are fixedly connected with fixing blocks 25, and the upper surfaces of the plurality of fixing blocks 25 are provided with clamping holes 26, and the cylinder 1 is provided with a rotation groove 27, and the rotation groove 2 7 is rotatably connected with a rotating shaft 28, a rotating block 29 is fixedly connected to the upper end of the rotating shaft 28, a clamping block 210 is fixedly connected to the lower surface of the rotating block 29, a fixed arc block 211 is fixedly connected to the inner wall of the annular groove 22, and two holding grooves 212 are symmetrically provided on the outer wall of the cylinder 1. The rotating shaft 28 drives the clamping block 210 to be clamped in the clamping hole 26 through the rotating block 29, and the corresponding arc clamping block 21 is fixed in the annular groove 22 through the clamping block 210 and the clamping hole 26, and then the cylinder 1 is pulled to drive the replacement hook 24 to be moved out for use.

[0020] The adjusting assembly 3 includes a round block 31, which is fixedly connected to the lower end of the rotating shaft 28. A plurality of slots 32 are provided on the upper surface of the round block 31. An indicating block 33 is fixedly connected to the outer wall of the round block 31. The plurality of slots 32 each corresponds to an L-shaped block 34. The round block 31 is pushed upward, and then the round block 31 is rotated to drive the rotating shaft 28 to rotate, so that the rotating shaft 28 drives the rotating block 29 to rotate. When the rotating block 29 rotates, it drives the clamping block 210 to rotate. When the clamping block 210 corresponds to the corresponding clamping hole 26, the round block 31 is released, and the L-shaped block 34 pushes the round block 31 to move downward, and the round block 31 pulls the rotating shaft 28 to move downward.

[0021] The disinfection component 4 includes a sealing ring 41, which is movably sleeved on the outer walls of multiple arc blocks 21. A clamping ring 42 is clamped on the inner wall of the upper end of the sealing ring 41. The outer wall of the upper end of the clamping ring 42 is fixedly connected to the inner wall of a sleeve 43. Two connecting joints 44 are symmetrically fixedly connected to the outer wall of the sleeve 43. High-temperature gas is input into the sleeve 43 through the two connecting joints 44 to disinfect and clean the replacement hook needle 24, and finally the disinfecting gas is discharged.

[0022] The fixed arc block 211 is clamped with multiple arc clamping blocks 21, and the fixed arc block 211 has the same shape as the multiple arc clamping blocks 21. The positions of the multiple clamped arc clamping blocks 21 are restricted by the fixed position of the fixed arc block 211 to prevent the arc clamping block 21 from varying in position during installation, which may cause the clamping block 210 to be unable to be clamped into the clamping hole 26.

[0023] The clamping block 210 matches the clamping hole 26 , and the thickness of the clamping block 210 is shorter than the distance between the rotating block 29 and the top inner wall of the groove 23 , so that the rotating block 29 can move upward to drive the clamping block 210 to move out of the clamping hole 26 .

[0024] The plurality of card slots 32 correspond to the plurality of card holes 26, and the indicator block 33 corresponds to the card block 210. The position of the card block 210 can be identified through the indicator block 33, so that the card block 210 can be rotated to be inserted into the corresponding card hole 26 to take the crochet hook.

[0025] An L-shaped groove 35 is provided at the lower end of the cylinder 1, and an L-shaped block 34 is clamped inside the L-shaped groove 35. A circular groove 36 is provided at the top of the L-shaped groove 35, and a spring 37 is clamped inside the circular groove 36. The L-shaped block 34 is pushed downward by the spring 37, and the L-shaped block 34 is inserted into the corresponding clamping groove 32 to stop the circular block 31 from rotating.

[0026] Specifically, an ultraviolet lamp 45 is embedded on the top inner wall of the sleeve 43 , and the replacement hook needle 24 is disinfected and sterilized by the ultraviolet lamp 45 .

[0027] When in use, firstly, a plurality of arc clamping blocks 21 with replacement hook needles 24 are clamped into the annular groove 22, and then the sealing ring 41 is sleeved on the outer wall of the plurality of arc clamping blocks 21, and then the clamping ring 42 is clamped into the sealing ring 41 to connect the sleeve 43 with the sealing ring 41, and then the sleeve 43 is inverted, and high-temperature gas is input into the sleeve 43 through two connecting joints 44 to disinfect and clean the replacement hook needles 24, and finally the disinfection gas is discharged, and the ultraviolet lamp 45 is started to disinfect and sterilize the replacement hook needles 24. When the hook needle needs to be used, the round block 31 is pushed up, and then the round block 31 is rotated to drive the rotating shaft 28 to rotate, so that the rotating shaft 28 drives the rotating block 29 to rotate, and when the rotating block 29 rotates, it drives the clamping block 210 to rotate, and when the clamping block 210 is aligned with the corresponding clamping hole 26 corresponds, the round block 31 is released, and the L-shaped block 34 is pushed downward by the spring 37. The L-shaped block 34 is inserted into the corresponding card slot 32 to stop the rotation of the round block 31. At the same time, the L-shaped block 34 pushes the round block 31 downward, and the round block 31 pulls the rotating shaft 28 downward. The rotating shaft 28 drives the clamping block 210 to be clamped in the clamping hole 26 through the rotating block 29. The corresponding arc clamping block 21 is fixed in the annular groove 22 through the clamping block 210 and the clamping hole 26. Then, the cylinder 1 is pulled to drive the replacement hook 24 to be moved out for use. Using the cylinder 1 to replace and take multiple hooks can reduce the cost of a single hook and avoid waste of resources. The replacement hook 24 is installed inside the sealing ring 41. When it is needed, the hook will be cleaned to prevent the hook from contacting the air and being contaminated.
