Embodiment 1
[0058] This embodiment is a computer-aided design method for making an individualized sternal prosthesis 1 applied to cases of sternal cartilage tumors.
[0059] 1. Using mimics software and CT data to reconstruct the three-dimensional model of the patient's chest, including the clavicle, the first rib to the fifth rib, the sternal manubrium and the sternal body model;
[0060] 2. Measure parameters such as cartilage tumor resection range, sternal length, clavicle distance, first inter-rib distance, second inter-rib distance, sternal cavity volume, etc. Measurement parameters can be increased according to actual needs.
[0061] 3. Use the modeling software to design the shape of the sternal prosthesis 1 with reference to the shape of the manubrium sternum; because the distance between the clavicles is 40.5 mm, the top length of the sternal prosthesis 1 is 36.0 mm, and the distance between the sternal prosthesis 1 and the clavicles on both sides is 36.0 mm. A gap of 2.25mm is ...
