Application of Medical Titanium Alloys in Medical Field _ Materials

0 oy

 Titanium and titanium alloys have the characteristics of good corrosion resistance, high specific strength, low elastic modulus, fatigue resistance and good biocompatibility. Compared with other metals, it has unique advantages due to its good biocompatibility, so it is widely favored in the medical field. However, due to its low wear resistance and process performance, efforts are being made to further improve it. With the rapid development of the national economy, the demand of biomedical titanium alloys is increasing in the medical field because of its excellent performance. As metal materials with excellent biological properties, titanium and its alloys have good application prospects in the field of medicine. However, compared with developed countries, there are still some gaps in the research and application of titanium alloy materials in China, such as high elastic modulus, poor surface activity, poor wear resistance and corrosion resistance of titanium alloys, which will directly affect the biocompatibility of materials. Therefore, in order to develop new titanium alloys with better comprehensive properties, China should strengthen the research and development of materials, pay attention to innovation, and develop biomedical titanium alloys with low elastic modulus, high wear resistance, corrosion resistance and excellent biocompatibility. Titanium has good affinity with human connective tissue and skeletal epithelial tissue, and its excellent mechanical properties also reflect its advantages in medical alloys. Titanium is widely used as denture (dental implant) because of its low density, light weight,titanium plate gr7, good corrosion resistance and comfortable wearing. In addition, after surface treatment, the aesthetic performance of titanium denture is increased, which can meet the needs of the public for beauty and give people visual enjoyment. 01. Direction for medical devices Medical titanium alloy medical instruments are the third generation of surgical instruments after carbon steel and stainless steel. In order to improve the anti-rust performance of stainless steel instruments, they are often subjected to surface treatment such as chromium plating and electropolishing. However, chromium is toxic, and the falling chromium layer will have a certain impact on the human body. Expand the full text The advantages of medical titanium alloy as medical devices are as follows: 1, the instrument is light and handy, the damage to blood vessels, muscles and organs can be reduced during the operation,titanium sheet grade 5, the fatigue of doctors can be reduced, and the medical titanium instrument is more suitable for fine microsurgery; 2, that corrosion resistance is good and non-toxic, the equipment doe not rust, the wound is not easy to infect, and the wound heals quickly; 3, the elasticity of the medical titanium alloy is moderate, and the medical titanium alloy is suitable for being used as instruments such as forceps, forceps, microscalpels and the like; 4. When operating under the shadowless lamp, the reflective performance of medical titanium is weaker, and it is more suitable than stainless steel; Medical titanium medical instruments mainly include: scalpel, surgical forceps, surgical forceps, thoracic expander, suture needle, suture line, etc. Compared with other materials (such as stainless steel wire), medical titanium wire used as surgical suture has the advantages of small tissue reaction and good torsion resistance. After suturing, ti6al4v ,titanium exhaust tubing, the surgical wound is not easily inflamed and the bone suture site is not easily displaced. Medical titanium wire (TA1 or TA2 wire) with a diameter of 0.5-0.8 mm is generally used as the suture. In addition, the soft elasticity produced by the titanium-nickel alloy wire can promote the rapid healing of the wound. In addition, medical titanium alloy is also an important material for auxiliary The research of titanium and titanium alloys has become a hot spot in the research of dental alloys. Titanium alloy porcelain teeth can restore the shape and function of teeth very well, and have high strength, beautiful appearance, stable color, smooth surface,nickel titanium wire, wear resistance and corrosion resistance. It is a permanent restoration, suitable for all fixed teeth, especially for people who are sensitive to nickel ions because of its good biocompatibility. It has been widely used in dental restoration. Return to Sohu to see more Responsible Editor:.
