Embodiment
[0040] A personalized total knee implant reverse design and manufacturing method, which combines computer-aided design technology, 3D printing manufacturing technology and investment casting technology, breaks the production barriers of traditional mold standardization, and is expected to create a new flexible production line. Improve production efficiency and improve medical level.
[0041] like figure 1 As shown, the process flow of the conventional (osteoarthritis, rheumatoid) total knee replacement prosthesis manufacturing method for patients with total knee replacement of the present invention is:
[0042] (1) Based on the standard medical image CT / MRI scanning raw data of the knee bone, the medical image processing software Mimics is used to process image segmentation, editing, and 3D calculation to reconstruct a 3D digital stereo model of the whole knee bone, including the femur and tibia and the menisci, such as figure 2 , image 3 , Figure 4 As shown, its shape ...
