Abstract

The invention provides a fractured end micro-movement and blood supply based fracture healing simulation system, relating to the field of biomedical engineering. The system is used for predicting a complicated process of fracture healing and exploring undetermined mechanisms in fracture healing. The system comprises a fracture healing simulation sub-system, an input module and a display module. The fracture healing simulation sub-system (1) comprises a geometry modeling module, a grid partition module, an environment initialization module, a biomechanical calculation module and a biological environment module. The biological environment module is used for creating a biochemical environment of callus in fracture healing so as to finish tissue differentiation in the callus. According to the system, blood supply is used as a dynamic variable and is introduced to the fracture healing simulation system, so that the fracture healing process can be simulated more accurately. The system can perform experiment simulation repeatedly, thereby helping to find out the best fractured end micro-movement value and the impact of blood on fracture healing.

Description

technical field

[0001] The invention relates to the field of biomedical engineering, in particular to a fracture healing simulation system based on micro-motion and blood supply of broken ends. Background technique

[0002] The musculoskeletal system plays an important role in the human body, and its main functions include: motor function, protective function, support function, hematopoietic function, and storage function. In the statistical data of common diseases that endanger people's health in our country, trauma has risen from the 9th in the early days of the founding of the People's Republic of China to the 4th in recent years with the development of industry and transportation. Fracture is a common trauma. The high incidence of fracture makes the study of fracture mechanism and promotion of healing particularly urgent. Once a fracture occurs, unlike other tissue damage repairs, the fracture is not connected by fibrous connective tissue, but by bone tissue. Fully rege...
