Surgical transplant rules using titanium 3d titanium wire electrode materials pure titanium electrode alloy and Ti 6 al - 4 veli. Recently, with the transplanting of human affinity good material Ti 6 al - 7 nb and Ti - 13 nb1-13 zr have also made the ASTM standard approval. The use of titanium electrode in artificial bone cells regeneration, in its bones can grow, titanium electrode with human bone, epithelium, create organizations have good affinity. In order to improve the connected to the bone implant material, the surface quality of coarsening surface of biological ceramic layer is more effective method. At present, the titanium electrode and electrode titanium alloy has been widely used in artificial joint, the artificial bone and joint pedal, broken bone holder, bone marrow nails, the artificial heart valve, skull, etc. According to statistics, every year in China, the demand for titanium titanium tubing price electrode alloy artificial joints is more than 5000 sets, the clinical application effect is good.
Medical titanium elastic modulus than the stainless steel electrode alloy is closer to the human body skeleton, suitable for human body in orthopaedic surgery. In terms of orthopaedic surgery, use more titanium nickel electrode shape memory alloy. Studies have shown that the NT - SMA is wear-resisting, corrosion resistance, shape memory effect, pseudo elastic and damping performance and the integration of new materials, such as increasingly wide application in orthopaedics, in addition to the commonly used bone plate and intramedullary pin, mandibular fixation, scoliosis correction thereof, changhai Titanium welding pipe hospital affiliated to Shanghai again on the NT - SMA series design and clinical application, such as the NT - patella, NT - arc fork nail, NT - bow, NT - ting device (such as specially designed for reconstruction of the sacrum), has obtained the satisfactory curative effect. For titanium alloy electrode material is applied to the human body, countries still kept trying to explore, to seek new titanium electrode alloy is more safe and reliable, for the benefit of the people all over the world.
Titanium electrode and electrode titanium alloy ti6al4v eli has good corrosion resistance, titanium electrode non-toxic, nonmagnetic, is a good selection of medical equipment. In the history of the development of surgical instruments, the first generation of surgical instruments use made of carbon steel, because after the plating performance can not titanium round bar meet the clinical use of demand and to be eliminated. Second to austenitic, ferritic and martensitic stainless steel surgical instruments, but the chromium in stainless steel composition has toxicity, loss of chromium plating layer has certain influence to the human body, therefore, the third generation - titanium electrode surgical instruments. Titanium electrode has the characteristics of light weight, make it particularly suitable for microsurgical operation. Titanium electrode has corrosion resistance, good elasticity, deformation, etc., resistant to repeated cleaning and disinfection surface ti6al4v quality is not affected; Nonmagnetic, can eliminate the tiny, sensitive features such as the destruction of the implanted electronic devices threat, the titanium electrode surgical instruments is more and more widely used. Has been used to make surgical blade, hemostatic forceps, scissors, electric bone drill, tweezers, etc.
