Abstract

The present invention discloses a preparation method of a titanium nail capable of loading a drug. The titanium nail capable of loading a drug includes a titanium nail body capable of loading a drug, and a microporous ceramic layer capable of loading a drug arranged on the surface of the titanium nail body. The steps of the method include: pretreating the surface of the titanium nail body, preparing a microporous mould for hyaluronic acid-alginic acid microspheres, preparing a titanium sol solution, coating film, pore-forming and calcining. It fails to generate the exfoliations and the wear debris to prevent the human body from 'wear debris disease' and reaction to a foreign body. Moreover, various drugs such as the antibacterial drugs, and the drugs for promoting the healing etc. can be loaded, targeted and slow-released, which is good for medical usage.
