General situation of application of domestic medical titanium alloy

Baoti group, the largest titanium and titanium alloy professional production enterprise in China, has been cooperating with other scientific research institutions in the research and development of titanium bone, titanium stent and other human implant materials since the 1970s, and achieved good results. Since the 1970s, China began to use titanium and titanium alloy artificial bone and joint for clinical treatment. The artificial femur and hip joint produced by the company are effective in clinical practice. In the mid-1980s, the number of domestic titanium and titanium alloy processing materials used in the manufacture of human implants has been increasing. In China, femoral head, hip joint, knee joint, elbow joint, shoulder joint, metacarpophalangeal joint made of titanium and titanium alloy were transplanted into human body, and very good results were obtained.

Significant progress has also been made in the development of new titanium alloys of beta type and titanium alloys for dental restorative applications in orthopedics. A variety of medical titanium alloys independently developed by shenyang metal research institute, Beijing nonferrous metal research general institute, northwest nonferrous metal research institute and other institutions have been used in surgical implants and vascular scaffolds.

In the application of porous titanium alloy, tangdu hospital of the fourth military medical university, northwest nonferrous metal research institute, Shanghai jiaotong university and other scientific research institutions have designed and manufactured porous titanium alloy implants, and a large number of clinical applications, has achieved good results.

The hard tissue defect caused by aging population has become a worldwide problem. China has a large population, the aging problem is very serious, the need for medical implant materials for rehabilitation surgery patients are also a lot of. According to statistics, the market for surgical implants in China has developed at an amazing speed in the past 30 years. The average growth rate in the past 10 years has been maintained between 15% and 30%, and it is expected to grow by more than 10% in the next 10 years. Therefore, titanium alloy implants have a very broad market prospect in China.

Although in surgical implants in China with the research and development and the application fields of titanium alloy material, a lot of research work has made significant progress, but compared with developed countries such as Europe, America, Japan, the titanium alloy implant product design, manufacturing, processing, equipment, surface treatment, technological level is a big gap, especially in some high-end implant products, domestic production of implant is difficult to meet the demand of the market, most of the high-end embedded parts need to be imported from abroad, this will give our country medical materials research unit, material producers and medical research institutions, clinical medical experts has brought unprecedented opportunities and challenges, These units should strengthen cooperation and work hard to realize localization of high-end implants, benefit the people and promote the healthy and steady development of China's medical titanium alloy industry.
