人工关节摩擦学的研究

The Development of Research in Tribology of Artificial Joints

无菌性松动是人工关节失效的主要形式,由磨损粒子在植入物与肌肉界面的聚集导致。本文从保持良好润滑、提高人工关节的耐磨性、减少敏感尺度磨损粒子产生和抑制磨粒引起的生物学反应等角度论述人工关节摩擦学研究的最新进展。提出从润滑材料设计、磨损控制和材料评价方法等方面改进人工关节设计的建议。

Aseptic loosening of the prosthesis is a major form for the failure of artificial joints, which results in the conglomeration of wear particles at the bone-lmplant interface. This paper briefly reviews the recent development of tribology of artificial joints preserving good lubrication, enhancing the wear resistance of materials for the joints, reducing the generation of sensltive-size particles and depressing the debrls-tissue reactions. Suggestion for improvement in the design of artificial joints is presented.
