23 Jul Simulation system for long bone fracture healing based on tissue differentiation
Abstract
The invention discloses a simulation system for long bone fracture healing based on tissue differentiation, and relates to the field of biomedical engineering. The simulation system is used for predicting the complicated process of the fracture healing and searching for the optimal scheme for the fracture healing. The system comprises a fracture area geometric modeling module, a fracture area biomechanics finite element analysis module, a callus unit tissue differentiation module and a program determination judging module. The fracture area geometric modeling module is used for establishing a three-dimensional geometric model of the fracture area; the fracture area biomechanics finite element analysis module is used for conducting finite element analysis on the established three-dimensional geometric model to obtain unit mechanical stimulation; the unit tissue differentiation module is used for simulating tissue differentiation and making the content of each tissue in the unit be updated; the program determination judging module is used for judging whether the program is determined or not. According to the simulation system for the long bone fracture healing based on the tissue differentiation, the fracture area is regarded as a diphasic porous elastic model, the fracture healing process can be more accurately simulated, and the system provides beneficial help for searching for the optimal scheme for the fracture healing.
