PROBLEM TO BE SOLVED: To provide a drug-carrying titanium screw, a drug-carrying titanium screw, and a preparation method thereof. The present invention discloses a method for preparing a drug-carrying titanium screw, wherein the drug-carrying titanium screw has a titanium screw body and a drug-carryable drug provided on the surface of the titanium screw body. And a pore ceramic layer. The method includes a pretreatment step of a titanium screw body surface, a preparation step of a hyaluronic acid-alginate microsphere that is a pore type, a preparation step of a titanium sol solution, a coating and pore forming step, and a firing step. . The present invention further discloses a drug-carrying titanium screw obtained by the above preparation method, a drug-carrying titanium screw prepared by the drug-carrying titanium screw, and a preparation method thereof. In the present invention, a porous ceramic layer is produced on the surface of a titanium screw body of a snout joint, and the ceramic has corrosion resistance and wear resistance. Therefore, metal ions on the titanium screw surface are difficult to enter the human body. At the same time, no fallout and wear powders are generated, avoiding `` inflammation due to wear powder '' and foreign body reaction to the human body, and being able to fill various drugs such as bacteriostatic drugs and fusion promoters and target localization. In addition, the drug is released slowly and has a good medical use. [Selection figure] None
