Abstract

The invention provides a sputtering target, a sputtering device and a prosthesis coating method. The sputtering target comprises a sputtering plate and a baffle, wherein sputtering holes are formed in the sputtering plate, and the baffle shields the sputtering holes and is movably arranged so as to adjust the circulation area of the sputtering holes shielded by the baffle. The sputtering target solves the problem that a prosthesis structure in the prior art is short in service life.

Description

technical field [0001] The invention relates to the field of medical treatment, in particular to a sputtering target, a sputtering instrument and a prosthesis coating method. Background technique [0002] Ti 6 Al 4 V alloy is widely used in the medical field because of its superior properties such as better biocompatibility, corrosion resistance, high strength, and elastic modulus similar to that of cortical bone. However, long-term use in the human environment will release Al and V ions. Al and V ions are toxic, carcinogenic and teratogenic to the human body. Moreover, Al makes the surface potential of Ti positively shift, which will lead to the deposition of fibrin and form thrombus in the environment in contact with thrombus fluid, which reduces the safety and reliability of material use. [0003] At present, the material used in some prosthetic structures is Ti 6 Al 4 V alloy, because the precipitation of Al and V ions will lead to aseptic loosening of the prosthes...
