[0002] General surgery fixation devices are a type of medical device used to fix and support bones, joints or soft tissues, and help treat fractures, joint instability, soft tissue injuries and other diseases; patellar fractures are also a common type of human fracture, often caused by falls or bumps; bone plates are often used in the treatment of patellar fractures. Bone plates are a type of medical device used to fix and support fractured bones and promote fracture healing. Bone plates are usually made of metal alloys, stainless steel or titanium alloys, and have the characteristics of high strength, good hardness and strong corrosion resistance.

[0003] In the related art, since the patellar plate needs to fit the outer curved surface of the patella, it is necessary to process curved surfaces on both sides of the plate. In the specific processing of the patellar plate, the workpiece to be processed is placed on a workbench and fixed, and a milling cutter is used to process the workpiece into a plate with a curved surface. The shape of the patella is milled out on the outer peripheral side of the workpiece according to the size of the patella by the milling cutter, thus completing the preliminary forming of the patellar plate, and then drilling and grinding and other operations are performed.
