medical titanium

   The past 10 years, the growth rate of biomedical materials and products market has remained at around 30%. In the biomedical materials, titanium and titanium alloys due to its pro-biotic characteristics, has become artificial joints, dental implants, interventional cardiovascular stents and other implantable medical class product material of choice. According to incomplete statistics, the world's disabled population of the world accounted for 1/20, and joint replacement patients receiving only about 1.5 million cases per year, and the number of those who are far from the actual needs replacement. Therefore, as a biomedical material of choice for Medical titanium alloy huge market demand. In our case, biomedical materials for surgical implant into the body about 80% of imported products, the high price limits its wide application. Therefore, increased research and development efforts titanium medical imperative. Has developed a variety of alloy materials are varying degrees of defects, such as relatively low wear resistance, corrosion resistance and can be further improved, the biological activity is not ideal. In order to improve the performance of medical titanium, but also in two ways, one is optimized alloy composition, the second is the titanium alloy surface modification.
    Medical analysis is mainly based on Medical grade titanium alloycomponents for medical research and development base five system Ti-Nb, Ti-Mo-based, Ti-Zr-based and Ti-Ta-based, Ti-Al-based alloy, and the selected literature are the art cited higher frequency patented technology literature. TiMo and TiNb tin alloy is the focus of the study, from 1982 to date, has submitted more patent applications; Judging from the number of alloying elements, TiNb alloy from the initial binary alloy gradually developed into triples, until now four element alloy; alloying element selected from the terms of the types, TiNb alloy from the initial metallic elements Zr, Fe, Ta, Sn, to the semiconductor elements Si, Ge, Ga, alloy elements are added to render the non-metallic species from the metal species trend. In future research, we can study them in a targeted manner to strengthen the weak technical means, look for opportunities to get involved in fewer areas in others. China needs to be optimized to strengthen ties in research and production, and increase the number of applications, strengthen innovation, and improve the layout and other aspects of the patent. The number of applications of titanium in the medical field has entered a steady growth, but the main universities and research institutions of the applicants, compared with foreign-based companies to the applicant, to the industrial transformation of scientific research is more a long road. Therefore, the need to strengthen domestic enterprises cooperation with universities and research institutions. Meanwhile, with the market needs to find technical focus and technical weaknesses, to promote the transformation of scientific and technological productivity. At present, many domestic applicants only concerned with the domestic market, even developed the core technology, but also only consider seeking protection in the country while ignoring the submission of applications for patents in foreign countries. If the technology or product enters the foreign market, because there is no protected by patent, the market competitiveness of their products will be greatly weakened, and even cause as a result of the infringement and can not enter foreign market. Therefore, the applicant should increase domestic foreign patent applications, improve the number of PCT patent application or with the family, to further improve the worldwide patent portfolio。
