When the internal joint shaving tool 2 rotates inside the external joint shaving tool 1, it can shave tissue, which can effectively meet the surgical operation requirements of orthopedic joints. The lower end of the operating handle body 3 is fixedly connected to a bottom operating handle 4, which is convenient for personnel to grip and operate. The lower end of the bottom operating handle 4 is fixedly connected to a quick fixation mechanism 5, which can be quickly connected to an external hose. The bottom operating handle 4 is electrically connected to an external controller through a connecting wire, which facilitates operation and control through the external controller.

[0026] The quick-fixing mechanism 5 includes a locking nut 51, an opening groove 52, an outer handle 53, an outer threaded tube 54, and an inner sleeve 55. The outer threaded tube 54 is fixedly connected to the periphery of the inner sleeve 55. A hose sleeve groove is provided between the inner sleeve 55 and the outer threaded tube 54, and the suction pump hose can be correspondingly sleeved on the periphery of the inner sleeve 55. The lower end of the outer threaded tube 54 has opening grooves 52 on both sides, so that the suction pump hose can effectively open the outer threaded tube 54 after being sleeved. The periphery of the outer threaded tube 54 is threaded... A locking nut 51 is provided, and outer handles 53 are fixedly connected to both ends of the locking nut 51. When the operator holds the outer handle 53 and drives the locking nut 51 to rotate in the forward direction, the locking nut 51 moves up and down around the outer screw tube 54. Then, the outer screw tube 54 squeezes the outwardly expanding part of the outer screw tube 54, thereby effectively locking the internal suction pump hose. This completes the installation and makes the installation operation more convenient. The inner sleeve 55 is installed and connected to the bottom operating handle 4, so that it can be installed and used accordingly.

[0027] In this invention, the quick-fixing mechanism 5 is connected to the external adsorption pump hose, so that it can be installed and used accordingly.

[0028] In this invention, the bottom operating handle 4 and the quick-fixing mechanism 5 are integrally molded by injection molding, which facilitates processing, preparation and use.

[0029] In this invention, an adsorption gap is provided between the outer joint planer 1 and the inner joint planer 2, which facilitates the discharge of the cut soft tissue.

[0030] In this utility model, the external joint planer 1 includes an external planer head 11, external planer teeth 12, and an external planer rod 13. The external planer head 11 is fixedly connected to the upper end of the external planer rod 13. The external planer head 11 can effectively extend the distance through the external planer rod 13. The external planer teeth 12 are fixedly connected to the opening of the external planer head 11. When the external planer teeth 12 cooperate with the internal planer teeth 23 of the internal joint planer 2, they can be effectively used for planing. The external planer rod 13 is installed and connected to the operating handle body 3, so that it can be placed and used stably.

[0031] Example 2

[0032] Reference Figure 1 , Figure 2 and Figure 4 A convenient orthopedic joint shaving tool, in this embodiment, compared to embodiment one, the bottom operating handle 4 includes a bottom suction hole 41, an operating handle housing 42, a drive motor 43, a first coupling 44, and a suction hole 45. The bottom suction hole 41 is provided on the lower inner side of the operating handle housing 42 to facilitate the discharge of shaving soft tissue. The drive motor 43 is fixedly connected to the middle of the inside of the operating handle housing 42. The output end of the drive motor 43 is fixedly connected to the first coupling 44. The output end of the drive motor 43 rotates... When in motion, it can drive the first coupling 44 to rotate. The first coupling 44 is connected to the inner joint planer 2, thereby driving the inner joint planer 2 to rotate for planing. The drive motor 43 has suction holes 45 on the periphery of the operating handle housing 42, so that the planed soft tissue can be effectively discharged. The upper end of the operating handle housing 42 is connected to the operating handle body 3, which facilitates installation and connection. The lower end of the operating handle housing 42 is connected to the quick fixing mechanism 5, which facilitates stable placement and use.

[0033] Example 3

[0034] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5An easy-to-operate orthopedic joint planer is described in this embodiment. Compared to Embodiment 2, the internal joint planer 2 includes a coupling short rod 21, an internal planer rod 22, internal planer serrations 23, and an internal planer head 24. The lower end of the internal planer rod 22 is fixedly connected to the coupling short rod 21, which is installed on a first coupling 44. Thus, the first coupling 44 can drive the coupling short rod 21 to rotate during rotation. The upper end of the internal planer rod 22 is fixedly connected to the internal planer head 24, which can be effectively extended through the internal planer rod 22. The outer side of the internal planer head 24 is fixedly connected to the internal planer serrations 23. When the internal planer serrations 23 match the outer planer serrations 12 of the external joint planer 1, they can be effectively used for planing. The internal planer rod 22 and the internal planer head 24 are sleeved on the external joint planer 1, allowing for positioning and rotation.

[0035] Working principle: During use, the operator holds the bottom operating handle 4 around its perimeter for easy gripping and operation. The lower end of the bottom operating handle 4 can be quickly connected to an external hose via a quick-fixing mechanism 5. When the bottom operating handle 4 drives the inner joint shaver 2 to rotate inside the outer joint shaver 1, tissue can be shaved, effectively meeting the needs of orthopedic joint surgery. The shaved tissue passes through the gap between the inner joint shaver 2 and the outer joint shaver 1 and is thus sucked into the bottom operating handle 4. It is then transported through the bottom operating handle 4 to the hose connected to the quick-fixing mechanism 5, and then through the hose to the external suction pump, and finally discharged externally for centralized collection.
