Problems solved by technology
After a part of the sacrum is resected, it is easy to have a great impact on the postoperative activities of the person, making it inconvenient for people to move, and it will also affect the ultimate load that the sacrum can bear. Therefore, it is necessary to use a sacral prosthesis to replace the resected bone.
[0003] In actual use, the required sacral prosthesis is often different in size and local shape, and the sacral prosthesis produced by traditional batch processing technology is likely to be different from the shape and size of the sacral prosthesis required by different patients. Big difference, which causes inconvenience in use
Therefore, there is a problem that the size does not match the actual demand in the prior art

Embodiment
[0026] A kind of personalized preparation method of human sacrum prosthesis, such as figure 1 shown, including the following steps:
[0027] S1. Extracting sacral shape data: using mimics to establish a three-dimensional model of the sacrum based on CT or MRI images. In this embodiment, the MRI image is used to establish a three-dimensional model of the sacrum;
[0028] S2. Virtual osteotomy: According to the operation plan, the three-dimensional model of the sacrum is subjected to simulated lesion treatment and virtual osteotomy to obtain the postoperative sacral shape model. The postoperative sacral shape model has the virtual osteotomy section left after the virtual osteotomy;
[0029] S3. Extracting the external contour model of the prosthesis: performing Boolean difference between the three-dimensional model of the sacrum and the shape model of the postoperative sacrum to obtain the external contour model of the prosthesis;
[0030] S4. Establishing the shape model of th...

The invention discloses a personalized preparation method of a human sacral prosthesis, which relates to the technical field of sacral prosthesis, and the problem that the size of the sacral prosthesis does not match the actual demand. The key points of the technique are: including the following steps: extracting sacral shape data; Form a personalized sacral prosthesis CAD model; 3D printing; post-processing. It eliminates the problem that the sacral prosthesis cannot match the patient's sacrum due to different physical characteristics of the patient, and the problem that the size of the sacrum that needs to be resected in different surgical plans does not match the size of the finished sacral prosthesis, and the size of the sacral prosthesis made by this method is realized. The effect of accurately matching the shape with the actual demand enables the sacral prosthesis to achieve a more precise size and bone ingrowth fusion effect, and at the same time have better compatibility with the human body.
Description
technical field [0001] The invention relates to the technical field of sacral prosthesis, in particular to a personalized preparation method of human sacral prosthesis. Background technique [0002] The sacrum is an important bone in the pelvis, which plays an important role in supporting the spine, maintaining the structure of the pelvis, and transmitting body loads. When patients with sacrum tumors go to the doctor, the tumors are often large, and in the process of sacral tumor resection, part of the tumor connected to the sacrum needs to be resected together. After a part of the sacrum is removed, it is easy to have a greater impact on the postoperative activities of the person, making it inconvenient for people to move, and it will also affect the ultimate load that the sacrum can bear. Therefore, it is necessary to use a sacral prosthesis to replace the removed bone. . [0003] In actual use, the required sacral prosthesis is often different in size and local shape, a...
