Technical Field

[0001] This application relates to the technical field of medical device processing, and in particular to a bone and joint planer grinding device. Background Technology

[0002] As is well known, in orthopedic clinical surgery, doctors use shaving blades extensively. Their main functions are: to shave and remove articular cartilage separated from the subchondral bone, to repair worn cartilage defects; to remove torn menisci, to repair worn and ruptured menisci; to remove spurs, to cut or grind bone; or to partially or completely remove and repair hypertrophic or inflamed synovial tissue, etc., in preparation for subsequent surgeries.

[0003] In the existing technology, the planer blade needs to first be machined to create the burr structure, then the corresponding position needs to be finely ground, and finally it needs to be inspected.

[0004] However, when machining burrs, existing planers typically use a single grinding wheel to create the burrs one by one, which is inconvenient and inefficient. Furthermore, in the current machining process, the grinding wheel toothing and the grinding of the burrs usually require two separate machines, resulting in high production costs.

[0038] A bone and joint planer grinding device includes a clamping device 10 and a tooth-opening device 20. The clamping device 10 clamps a planer processing profile 11, and the tooth opening depth on the processing profile 11 is h1.

[0039] The tooth-cutting device 20 includes an electronically controlled base 21 and a tooth-cutting mechanism 22 connected to the electronically controlled base 21. The tooth-cutting mechanism 22 includes an adjustable connecting rod 221 and at least one set of tooth-cutting assemblies 222. The connecting rod 221 is provided with at least one set of longitudinal limiting grooves 221A. The set of longitudinal limiting grooves 221A includes three longitudinal limiting grooves 221A, which are arranged in a circular array around the center of the connecting rod 221 on the side wall of the connecting rod 221. The connecting rod 221 is also provided with at least A set of transverse limiting grooves 221B, comprising fourteen transverse limiting grooves 221B. Specifically, the distance between adjacent toothed pieces 2222 of the toothed assembly 222 is adjusted by the mutual cooperation between the transverse limiting grooves 221B and the toothed pieces 2222. The longitudinal limiting groove 221A is rectangular, and the transverse limiting groove 221B is arc-shaped. The longitudinal limiting groove 221A and the transverse limiting groove 221B intersect each other. The toothed assembly 222 is provided with a sandpaper positioning hole 222A, and a clamping mechanism 2221 is connected to the sandpaper positioning hole 222A. Specifically, a set of toothed assemblies 222 includes seven toothed pieces 2222. A connecting hole 2223 is provided at the center of the toothed piece 2222. An arc-shaped protrusion 2224 is provided inside the connecting hole 2223. The arc-shaped protrusion 2224 cooperates with the transverse limiting groove 221B. At least one set of limiting strips 2225 is also provided on the inner side wall of the connecting hole 2223. The limiting strips 2225 cooperate with the longitudinal limiting groove 221A, thereby realizing the transverse adjustment and longitudinal limiting of the toothed piece 2222 along the connecting rod 221. Furthermore, a set of limiting strips 2225 includes three limiting strips 2225. The three limiting strips 2225 are arranged in a ring around the center of the connecting hole 2223 on the inner side wall of the connecting hole 2223.

[0040] The toothed plate 2222 includes a toothed portion 22221 and a positioning portion 22222. The height of the toothed portion 22221 is h1, and the height of the positioning portion 22222 is h2. The positioning portion 22222 is provided with at least one set of sandpaper positioning holes 222A. A clamping mechanism 2221 is connected to the sandpaper positioning holes 222A. The clamping mechanism 2221 includes a clamping plate 22211 and a locking member 22212 connected to the clamping plate 22211. The locking member 22212 passes through the clamping plate. 22211, The locking member 22212 is provided with an external thread (not shown in the figure). A set of sandpaper positioning holes 222A includes four sandpaper positioning holes 222A. The sandpaper positioning holes 222A are provided with internal threads (not shown in the figure). Specifically, after the locking member 22212 passes through the pressure plate 22211, its external thread is threaded to the internal thread on the sandpaper positioning hole 222A to realize the connection between the locking member 22212 and the sandpaper positioning hole 222A. Here, the clamping device 10 in the bone joint planer grinding device clamps the planer processing profile 11, and the tooth opening depth on the processing profile 11 is h1. The tooth opening device 20 includes an electronically controlled base 21 and a tooth opening mechanism 22 connected to the electronically controlled base 21. The tooth opening mechanism 22 includes an adjustable connecting rod 221 and at least one set of tooth opening components 222. The tooth opening components 222 are provided with sandpaper positioning holes 222A. A pressing mechanism 2221 is connected to the sandpaper positioning holes 222A. The connecting rod 221 is provided with at least one set of longitudinal limiting grooves 221A and at least one set of transverse limiting grooves 221B. This improves the convenience and efficiency of operation in the tooth opening process of the planer during processing, and effectively reduces production costs in the tooth opening and burr grinding process.

[0041] To facilitate understanding, the working principle of this application is further described as follows: In the production process, the bone joint planer grinding device clamps the processing profile 11 using the clamping device 10. The distance between the clamping device 10 and the tooth-opening device 20 is manually adjusted to ensure that the tooth opening depth on the processing profile 11 matches the height of the toothed portion 22221 on the tooth-opening plate 2222. Furthermore, based on the required distance between adjacent teeth in the processed spike structure, the tooth-opening plate 2222 is pried open using an external tool to adjust the distance between adjacent tooth-opening plates 2222. The lateral position of the tooth-opening plate 2222 is fixed through the interaction between the transverse limiting groove 221B and the arc-shaped protrusion 2224. The longitudinal limiting groove 221A and the limiting strip 22... The cooperation between 25 enables the planer to simultaneously open multiple teeth during the tooth-opening process to form a burr structure, improving the convenience and efficiency of operation. It also fixes the axial position of the tooth-opening piece 2222, preventing displacement, rotation, slippage, or shaking of the tooth-opening piece 2222 in the lateral and axial directions during operation. It should be noted that the distance between the teeth on the burr structure of the bone joint planer can be greater than or equal to zero within the standard specifications, depending on actual needs. Since the lateral limiting groove 221B and the arc-shaped protrusion 2224 fit tightly, they will not fall off during operation. However, during adjustment, external tools are needed to pry and move the tooth-opening piece 2222.

[0042] Furthermore, by pressing a grinding paper of the required specifications that is compatible with the shape of the toothed portion 22221 and the positioning portion 22222 of the toothed disc 2222 under the action of the clamping plate 22211, and by the mutual cooperation between the locking member 22212 and the sandpaper positioning hole 222A, the grinding paper is installed. The toothed disc 2222 is rotated in the same way as the toothing process to grind the barbed structure. This allows the grinding of the toothed disc and the barbed structure to be completed on one machine, effectively reducing production costs.
