[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a multifunctional bone and joint cutting and peeling device, including a sleeve 1, with an anti-rotation limiting member 2 fixedly connected to the bottom of the sleeve 1, and a ball lock connector 3 rotatably connected to the bottom of the anti-rotation limiting member 2. The sleeve 1 is provided with an anti-slip sleeve 4 on the outside, which is made of rubber and has anti-slip texture 41 on its surface to enhance grip stability and reduce the risk of slippage during surgery. A cutting and peeling tool 5 is snapped into the inside of the sleeve 1. The cutting and peeling tool 5 includes a tool handle 51, and a tool head 53 is fixedly connected below the tool handle 51. The tool head 53 includes a bone scalpel head, a bone file head, a bone chisel head, etc. In use, by using a uniform tool handle 51, it is convenient to insert various cutting and peeling tools 5 into the sleeve 1 and fix them by the ball lock connector 3 and the anti-rotation limiting member 2, avoiding the problem of traditional tool handles being thin and long and inconsistent in style affecting the feel, thereby achieving a uniform grip and improving operational stability.

[0024] The ball lock connector 3 includes a rotating sleeve 31. Several balls 32 are provided in the opening in the bottom tube wall of the rotating sleeve 31. A sliding sleeve 33 is slidably connected to the outside of the ball lock connector 3. A locking spring 34 is fixedly connected to the inside of the sliding sleeve 33 and the ball lock connector 3. The surface of the handle 51 of the cutting and peeling tool 5 has equidistant spherical holes 52. In use, the sliding sleeve 33 slides downward under the push of the locking spring 34, pushing the balls 32 inward, thereby achieving a locking effect. When it is necessary to insert the cutting and peeling tool 5, the sliding sleeve 32 is pulled upward to release the fixation of the balls 32, so that the handle 51 can be inserted smoothly. After the sliding sleeve 32 is released, when the spherical hole 52 of the handle 51 coincides with the position of the balls 32, the balls 32 are pressed into the spherical hole 52 by the sliding sleeve, thereby completing the locking. By setting multiple sets of equidistant spherical holes 52, the distance between the tool head 53 and the hand can be flexibly adjusted, thereby meeting the needs of different scenarios and the working habits of doctors.

[0025] The anti-rotation limiting component 2 includes a fixed sleeve 21, with a rotating sleeve 22 slidably connected to the outside of the fixed sleeve 21. The outer surface of the top end of the fixed sleeve 21 has an external thread 211, and the inner surface of the top end of the rotating sleeve 22 has an internal thread 221. A limiting spring 23 is provided between the rotating sleeve 22 and the fixed sleeve 21. Several limiting plugs 24 are fixedly connected to the bottom of the rotating sleeve 22, with a gap between each pair of limiting plugs 24. A limiting slot 35 is provided on the outer side of the upper part of the sliding sleeve 33 of the ball lock connector 3, corresponding to the limiting plugs 24 at the bottom of the anti-rotation limiting component 2. A hexagonal handle 54 is fixedly connected to the end of the peeling tool 5. In use, initially, the rotating sleeve 22 is pushed downwards under the action of the limiting spring 23. The limiting plug 24 of the part is inserted into the limiting slot 35 above the sliding sleeve 33 of the ball lock connector 3, so that the anti-rotation limiting part 2 can fix the ball lock connector 3 and prevent it from driving the cutting tool 5 to rotate. When using tools that require rotation, such as bone chisels, pull the rotating sleeve 22 upward until the internal thread 221 contacts the external thread 211 of the fixed sleeve 21, release the fixing of the limiting plug 24 and the limiting slot 35, and then rotate the rotating sleeve 22 to fix the rotating sleeve 22 by threaded connection to prevent it from sliding down under the action of the limiting spring 23. At this time, the doctor can rotate the hexagonal handle 54 or connect the orthopedic electric drill to the hexagonal handle 54 to operate on the bone joint, while the other hand can hold the anti-slip sleeve 4 to control the direction to ensure stability.

[0026] Example 2

[0027] Please see Figure 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a ramp 311 is provided at the bottom opening edge of the rotating sleeve 31. The ramp 311 can provide guidance when the cutting and peeling tool 5 is inserted from the bottom of the rotating sleeve 31. Under the action of the ramp 311, the cutting and peeling tool 5 can be smoothly inserted into the rotating sleeve 31 without complete alignment, saving time for fixing and replacing the cutting and peeling tool 5.
