Document Type and Number:
WIPO Patent Application WO/2017/047912
Kind Code:
A1
Abstract:
The present invention relates to a bioimplantation metal having a nano-patterning groove surface, a method for preparing the metal, an implant, a method for manufacturing the implant, a stent, and a method for manufacturing the stent. The subject matter of the present invention comprises the steps of: forming a titanium oxide nanotube by anodizing a metal base comprising titanium metal or a titanium alloy; and forming a groove on a surface of the metal base by removing the titanium oxide nanotube. Therefore, a groove is formed on the surface by removing the anodized surface after anodizing the surface of a metal base, and an anodized titanium oxide film is stripped off such that a leak thereof from the inside of a living body is prevented and impurities remaining on the surface are effectively removed. In addition, when titanium or a titanium alloy for bioimplantation, is used as a metal base material and is bioimplanted by the groove formed through surface anodizing, such that the surface area is maximized, thereby having excellent bioaffinity, chemical compatibility and mechanical compatibility during bioimplantation, and various sizes of grooves comprising nano-patterning can be formed by carrying out anodizing in combination with sandblasting or sandblasted, large-grit, acid-etched (SLA) method.
