BIOMATERIAL, ARTIFICIAL JOINT USING THE SAME AND METHOD OF PRODUCING THE SAME

摘要

It is intended to provide an artificial joint and an artificial slide member, whereby friction at a slid site can be prevented in repeated daily performances and the generation of friction powder can be reduced, and a method of producing the same. To achieve the above-described object, there is provided a biomaterial comprising a base made of a metal, an alloy or a ceramic material and a biocompatible material layer laminated on the base at an appropriate part thereof, wherein the base has hydroxyl groups formed by a surface-treatment at least at required positions on the surface thereof, the biocompatible material layer is made of a high-molecular polymer containing phosphorylcholine group and the base material and the biocompatible material layer are bonded together via a binder layer capable of binding to both of the hydroxyl groups and the biocompatible material.
