Skeleton model construction method and device, computer equipment and storage medium

Abstract

The embodiment of the invention discloses a skeleton model construction method, which comprises the following steps of: obtaining a geometric model according to scanning data of the skeleton of a patient, and setting physical parameters to obtain an original model; applying boundary conditions and loads to the original model, performing simulation analysis to obtain boundary displacement data; setting different material parts in the geometric model as at least one isotropic material, and performing inversion calculation according to preset boundary conditions, loads and boundary displacement data to obtain physical parameters of the isotropic material; and assigning the physical parameters of the isotropic material to the geometric model to obtain a skeleton model. According to the method, the physical parameters of the simplified model capable of characterizing the physiological mechanical characteristics of the original model are reversely deduced through the inversion calculation, so that the simplified skeleton model is obtained, simulation analysis is carried out, and an accurate analysis result can be obtained under the condition that the simulation analysis calculation amount is reduced. In addition, the invention also discloses a skeleton model construction device, computer equipment and a storage medium.

Description

technical field [0001] The invention relates to the technical field of skeleton model simulation, in particular to a skeleton model construction method, device, computer equipment and storage medium. Background technique [0002] Clinically, spinal fusion is the main method for treating spinal diseases, and intervertebral cages are widely used in cervical and lumbar spinal fusion operations. In spinal fusion surgery, fusion cages have the advantages of achieving immediate postoperative stability, distracting and maintaining intervertebral space height, and promoting bone graft fusion, so they have been rapidly developed in clinical use. At the same time, due to the mismatch between the specifications of the intervertebral fusion cage and the pathological environment of the patient, more and more people pay more and more attention to the phenomenon of fusion failure such as subsidence, displacement, and non-fusion of the intervertebral fusion cage after surgery. Therefore, h...

Problems solved by technology

Since the real human bone is a heterogeneous material, the material properties of its endplate, nucleus pulposus, annulus fibrosus and other tissues are different. If the real parameters of these materials are fully used in the process of designing the fusion cage, although relatively accurate simulation results can be obtained , but it will bring about a substantial increase in the amount of computation
