Construction method of bone scaffold for treating femoral head necrosis

The invention belongs to the technical field of bone scaffold design, and provides a bone scaffold construction method for treating femoral head necrosis, which comprises the following steps of: firstly, detecting the bones of a patient for multiple times by using a CT (Computed Tomography) technology to obtain multiple groups of data, and then analyzing and processing the data to accurately obtain the bone data of the patient; then, according to the porosity of the skeleton structure of the patient and the position and size of a necrotic area, computer aided design software is used, and three-period minimal curved surfaces (TPMS) of different structure types are combined to generate an optimal bone scaffold with high adaptability; by using the medical imaging technology, detailed skeleton data including the shape, the size and the lesion condition can be obtained, then the bone scaffold design accurately matched with the anatomical structure of the patient is generated through the data, the accurate shape an
