Biomedical materials, also known as biological material, its research and development began in the 30 s of this century, obtained the rapid development in recent 20 years. It has been listed as high technology and new materials development planning in many countries, and quickly became a competitive world of high technology key to one of the important areas of new materials; It to the health of human life and the country's economic and social harmonious development, is of great significance.
Refers to a kind of biomedical materials with special performance, special function, used in artificial organs, surgical repair, physical therapy rehabilitation, diagnosis and treatment of diseases, and won't produce adverse effect to human body material. Now all kinds of synthetic materials and natural polymer materials, metal and alloy material, ceramic and carbon materials as well as a variety of composite materials, the finished products have been widely applied in clinical and scientific research. A, the classification of biomedical materials In general, the clinical medicine of biomedical materials have the following basic requirements: non-toxic, no carcinogenic, teratogenic, does not cause the burst of human cells and tissue reaction; Has good compatibility with human tissue, not cause poisoning, hemolysis, blood coagulation, the phenomenon such as fever and allergies; Chemical stability, resistance to bodily fluids, blood and enzyme; Has adapted to the natural organization of physical and mechanical properties; According to different purpose has a specific function.
