Title:
MULTIDIRECTIONAL PHOTOFUNCTIONALIZATION INSTRUMENT FOR SURFACE MODIFICATION OF TITANIUM ALLOY IMPLANT AND METHOD OF USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/268035
Kind Code:
A9
Abstract:
A multidirectional photofunctionalization instrument for surface modification of a titanium alloy implant and a method of use thereof. The instrument comprises at least two ultraviolet light sources which can emit ultraviolet light, such that modification processing can be performed on a titanium alloy structure which is located in the instrument. Furthermore, the ultraviolet light source may comprise ultraviolet lamps which emit at least two types of ultraviolet light having different wavelengths. By means of the method, irradiation is performed from different angles, or titanium alloy is treated by using at least two types of ultraviolet light having different wavebands, such that the performance can be significantly improved on a surface of a titanium alloy structural member and both an outer surface and an inner surface of a porous titanium alloy structure.
