Embodiment Construction
[0028] Such as figure 1 , figure 2 As shown, the personalized hemipelvic prosthesis disclosed in this embodiment is composed of three parts: the sacral base 1, the connecting piece 2 and the femoral joint handle 3, and the sacral base 1 and the femoral joint handle 3 pass through the connecting piece 2 Connected, each part has a modular design, which is convenient for intraoperative installation.
[0029] In order to comply with the biomechanical channel, the sacral base 1 is designed in the following way.
[0030] In practical application, since the patient intends to resect the pelvis on the diseased side and be destroyed by the tumor, the data is imported into reverse engineering software to mirror the pelvis on the healthy side of the patient, and then the complete pelvic imaging data is imported into Mimics software to reconstruct a three-dimensional image. Store and output the 3D image in STL format, then import it into Geomagic Studio software to pre-process the 3D i...
