COMPOSITION AND APPLICATION THEREOF, JOINT IMPLANT PROFILE AND PREPARATION METHOD THEREFOR, AND JOINT IMPLANT AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to the technical field of materials, and provides a composition comprising ultra-high-molecular-weight polyethylene and an anti-infective agent. The composition is used in an anti-infective artificial joint implant, and can continuously produce the abrasive dust along with the joint movement. The abrasive dust contains the anti-infective agent, and the release of the anti-infective agent is a slow and sustained process, and therefore, the abrasive dust can provide the uniform and long-term infection control effect. The present invention also provides a profile for preparing an anti-infective artificial joint implant, an anti-infective artificial joint implant, and preparation methods therefor.
