摘要
Abstract
BACKGROUND: Near-equiatomic nickel-titanium shape memory alloy can be used as a type of ideal biological implant material based on its deformation rate of 8%, million times in the number of cycles, excellent corrosion resistance and low elastic modulus, low magnetism, and radiopacityOBJECTIVE:To discuss the surface modification and bio compatibility of the medical near-ec|ui atomic nickel-titaniumMETHODS:A computer-based online search was performed in PubMed database and Wanfang database for literatures from January 1990 to December 2008 related to surface chemical treatment and chemical modification of medical nickel-titanium shape memory alloy and dissolvabihty of nickel after implantation of the alloy into biological tissues RESULTS AND CONCLUSION:Near-equiatomic nickel-titanium shape memory alloy has high nickel content However, there has been controversy about the safety after long term implantation of the alloy in vivo Alloy surface modification ismodification of nickel-titanium shape memory alloy, and many related research works have been done by domestic and overseas scholars However, studies about the metabolic process of Ni ion in vivo after implantation of nickel-titanium alloy are not comprehensive and systematic.关键词
