Abstract

The invention belongs to the medical field, and discloses a mouse femur bone defect model and a multifunctional fixing system thereof. The fixing system comprises a near-infrared light radiation source, a detection unit, a data acquisition unit, a processor unit, a target image processing unit and a reconstruction unit. The multifunctional fixing system is used for constructing the mouse femur bone defect model. The invention aims to construct a middle and distal femur bone defect model, the preparation method of the model is simple, and the constructed bone defect model has good uniformity and repeatability. After the model is constructed, the survival rate and recovery rate of experimental animals are high, experimental animals feel less pain after an operation, activities of experimental animals are basically unaffected, there is no obvious tissue reaction, and rapid, effective, time-saving and effortless model construction is realized.

Description

technical field

[0001] The invention belongs to the medical field, and in particular relates to a mouse femoral bone defect model and a multifunctional fixation system thereof. Background technique

[0002] At present, femoral head necrosis is a disease in which the blood supply of the femoral head is interrupted or damaged, resulting in the death and subsequent repair of bone cells and bone marrow components, which in turn leads to structural changes of the femoral head, collapse of the femoral head, and joint dysfunction. Femoral head necrosis, also known as avascular necrosis of the femoral head, is a common refractory disease in the field of orthopedics. ONFH can be divided into two categories: traumatic and non-traumatic. The former is mainly caused by hip trauma such as femoral neck fracture and hip dislocation. The latter is mainly caused by the application of corticosteroids and alcoholism in my country. With the development of economy and society, various factors s...
