In 1972, China began to accept the domestic titanium fan and titanium alloy products, Beijing Jishuitan Hospital and other more than 20 hospitals, has accepted titanium and titanium alloy artificial bone and head off head for clinical treatment applications and research, the manufacture of the hip head off head, elbow head off head, jawbone and so on for clinical treatment of patients. At the same time, Huashan Hospital and Shanghai Metallurgical Research Institute of simulated human body fluids immersion implementation, electrochemical anodization implementation and erosion kinetic curve determination, proved that the night white titanium and titanium alloy artificial bone and head for human body with excellent erosion resistance, biological reflections are also very small, it is a kind of ideal human implants. Fudan University, Department of Biology, Human Psychology Research Group and the Shanghai Sixth People's Hospital of implanted human bones and the head of the mechanical function of the determination, feel that the strength of titanium and titanium alloys to meet the requirements of the human implant.
Related research and nightly clinical treatment examples in various countries across the country have recognized titanium coils and titanium alloys as the most ideal metal material for human implants to date, and have been listed as the third-generation metal in today's medical and surgical industry following stainless steel and cobalt-based alloys.
The 20th century after the mid-80's, the number of domestic titanium and titanium alloy processed materials used in the manufacture of human implants increased, of which the development and application of titanium shape memory alloys to reach the international advanced level. By the mid-1990s, domestic titanium and titanium alloy processing materials, in orthopedic surgery, neurosurgery, cardiovascular system, oral and maxillofacial surgery, the human body outside the machine and other aspects of the general application. In the past five years, there are a number of enterprises such as Tianjin Weiman Biomaterials Co., Ltd. and Beijing Osbilic New Technology Co., Ltd. have become titanium and stainless steel and other human implants production enterprises. Accept titanium and titanium alloy manufactured femoral head, hip head, humerus, skull, knee head, elbow head, shoulder head, metacarpal finger head, jawbone, as well as the heart discernment membrane, kidney discernment membrane, vasodilator, splints, prostheses, fastening screws and other hundreds of metal parts transplanted into the human body, achieved exquisite efficacy, was given a high evaluation by the medical profession.
The human body implant is a special effect material that is closely related to human life and health. Comparison with other metal materials, manipulation of titanium and titanium alloy advantages are mainly six: 1, light; 2, low modulus of elasticity; 3, non-magnetic; 4, non-toxicity; 5, erosion resistance; 6, high strength, good toughness.
Titanium and titanium alloy has excellent manipulation characteristics, is nationally recognized as a biomedical scale of excellent metal materials, with the manipulation of stainless steel, cobalt-based alloys and other metal materials against the force of calculation, with the advantages of the application of the night, the development of the space is very night.
Metallic materials as human implants gradually increase the amount of 1990 years later, only the United States each year for the human body implantation of metal parts to reach more than 2 million, of which the medulla oblongata, femur parts accounted for 2.5%; European market on the fracture of the external smooth products and internal smooth product supply and demand, France, Germany, Italy and the United Kingdom, mainly in 2004, the market price reached 2-8 million U.S. dollars, of which the internal smooth products, the market price of the products to reach 2.5%, the market price of the products to reach 2.5%. In 2004, the market price reached 2.8 billion U.S. dollars, of which the internal smooth products accounted for 85.7%. In the past 10 years, biomedical materials and products market growth rate has been linked to 20% to 25%, looking forward to the next 10 to 15 years, including biomedical materials, medical tools, including the rapid development of the property, will reach economies of scale, become a pillar of the national economy.
Medical titanium and titanium alloy material advantages have been recognized by the medical profession, but also more and more patients as, taking into account the identity of the war, the identity of the trauma of the hook and the identity of the advancement of the level of retention of the people near the identity of the preferred titanium and titanium alloy as a human body implants diffusion space is very large, it is bound to become the development of titanium application of a new point of economic growth.
