A surface treatment method for bone joint implants based on Bessel beam |
| abstract |
The present invention provides a surface treatment method for a bone joint implant based on a Bessel beam, comprising: pre-processing the surface of the implant to be treated to obtain a first implant; The surface of the implant is processed to generate a micro-nano composite periodic structure on the surface of the first implant to obtain a second implant; polydopamine is deposited on the surface of the second implant to obtain a third implant; A functional substance is deposited on the surface of the third implant to obtain a fourth implant; the fourth implant is rinsed with deionized water and dried to obtain a final implant. The invention can be used for the processing of curved metal implants, and the micro-nano composite periodic surface structure can promote cell differentiation through wear resistance, polydopamine lubrication and the antibacterial and anti-inflammatory functions of functional components, so that the implants have better composite functions and improve The osseointegration properties, durability and implantation success rate of osteoarticular medical implants are improved, and implantation side effects are reduced. |
