発明の名称 (英語) ARTIFICIAL JOINT 新技術説明会
発明の概要(英語) An artificial joint configured so that the wear of friction materials is minimized and that bioactivity due to wear powder generated from friction surfaces is minimized. An artificial hip joint (10) is provided with a ball (20) and a cup (30) which are a set of joint members for configuring a joint, the set of joint members having formed therebetween a convex surface (21) and a concave surface (31) which are a pair of friction surfaces which slide relative to each other while being in contact with each other with a lubricating liquid (40) therebetween. Of the convex surface (21) and the concave surface (31), the convex surface (21) which is at least one friction surface is provided with: recesses (23) which are formed at least in a groove shape or a hole shape having a width gradually reduced from the front surface side toward the inner side of the convex surface (21); and curved surfaces (24) each smoothly connecting a sloped surface (23a) which forms a recess (23) and a surface which forms a front surface of the convex surface (21). Preferably, the recesses (23) have a depth in the submicron range.
