3. The method for preparing a blood-staining-resistant self-cleaning surgical instrument as claimed in claim 2, wherein the mechanical polishing is performed by polishing with an abrasive material or sand paper of 800# or more, and the ultrasonic cleaning time is 4-6 min.
4. The method for preparing the blood-staining-resistant self-cleaning surgical instrument as claimed in claim 1, wherein in step S2, the diameter of the nano ceramic particles is 10-100 nm, the nano ceramic is one or more of alumina ceramic, silicon nitride ceramic and silicon carbide ceramic, the filter screen is 400 meshes or larger, the lubricant is one or more of perfluoropolyether oil, dupont krytox, perfluorotripentylamine and silicone oil, and the mass ratio of the coating containing the nano ceramic particles to the lubricant is 1:1 or larger.
5. The method of claim 1, wherein in step S3, the coating is performed by one of spraying, brushing, rolling and dipping, and the coating is applied once.
6. The method of claim 1, wherein in step S3, the portion of the surgical instrument to be treated is dipped in the mixed coating and then coated, and the mixture is dipped sufficiently and then allowed to stand at an angle to form a uniform coating on the surface of the portion of the surgical instrument to be treated.
7. The method for preparing a blood-staining-preventing self-cleaning surgical instrument as claimed in claim 6, wherein the inclination angle is 15-50 °, and the inclined standing time is 20-40 min.
8. The method of claim 1, wherein in step S4, the surgical instrument is taken out of the mixed paint, and then naturally dried or quickly surface-dried, and then placed at room temperature to ceramize the paint on the portion of the surgical instrument to be treated.
9. The method for preparing a blood-staining-preventing self-cleaning surgical instrument as claimed in claim 8, wherein the time for standing at room temperature is 1-2 hours.
10. A blood-staining-preventing self-cleaning surgical instrument, which is prepared by the preparation method of the blood-staining-preventing self-cleaning surgical instrument as claimed in any one of claims 1 to 9.
