Application of Medical Titanium Alloy in Medical Field
Medical titanium alloy as a new alloy, but also a carrier material, is commonly used in limb implantation, alternative functional materials, dental, medical equipment and other related fields. Titanium and titanium alloys are: good corrosion resistance, high specific strength, low elastic modulus, fatigue resistance, good biocompatibility and so on. The biocompatibility of this feature makes it unique advantages compared with other metals, so in the field of medicine has been widely favored, but because of its wear resistance and process performance is not superior, committed to its further improvement work In progress.
With the rapid development of the national economy, medical titanium alloy with its excellent performance, increasing demand in the therapeutic field. As good biological properties of metal materials, titanium and its alloys in the field of medical applications of good prospects. However, compared with developed countries, the development and application of titanium alloy materials in China there are still some gaps, such as: titanium alloy elastic modulus is high, poor surface activity, wear resistance and poor corrosion resistance and other shortcomings are Will directly affect the biocompatibility of the material. Therefore, in order to develop a new titanium alloy with better overall performance, China should increase the research and development of materials, pay attention to innovation, develop low elastic modulus, high wear resistance, corrosion resistance and excellent biocompatibility of biomedical Titanium alloy material.
Titanium and human connective tissue, bone epithelial tissue has a good affinity, excellent mechanical properties also reflects its advantages in medical alloys. And the density is small, lightweight, good corrosion resistance, wearing comfortable, therefore, titanium as denture (dental implant) received wide favor. In addition, titanium denture through the surface treatment, the aesthetic performance increases, to meet the needs of the public in the United States, giving a visual enjoyment.
According to the relevant literature, about 100 million patients in the world each year suffering from knee and arm joints and other related inflammation, the replacement of surgical treatment is imperative, so with superb replacement function of the titanium alloy to bring the gospel. Compared with ceramics, stainless steel and other materials, the elastic modulus of titanium alloy is closer to the human skeleton. In the modulus size is more advantages. So titanium alloy in the ankle, elbow and further corrections can be widely used. In addition, the porous titanium alloy material can make the prosthesis has biological activity, contribute to the healing of the femoral head; titanium alloy biocompatibility is good, can induce bone cell growth, so by clinicians, orthopedic experts in the field of respected The
The advantages of high-strength, chemical stability and biocompatibility are good; non-toxic, the human body will not cause harm; low elastic modulus, And the human body bone more match; memory alloy has the flexibility and shape recovery function. In summary, titanium in the application of skull repair is mainly reflected in: the use of titanium mesh can repair the defect in the skull. In the human cardiovascular application is reflected in: the preparation of artificial heart valves, blood filters, pacemakers and artificial heart pumps.
