Description
インプラント、即ち、置換関節部及び/又はさらなるコンポーネントは、例えば、上腕骨頭人工関節、大腿骨頭人工関節、大腿骨人工関節コンポーネント、顆部関節置換及び/または半月板の交換や距骨体人工関節から構成することができる。
基体504は、不規則な輪郭線514とハッチング516により図5で提示されている粗面化された表面で形成されており、例では、関節丘502全体をカバーしている。従って、キャップ510は、局所的に平坦な基体に配置されず、関節丘502のキャップ510の改善された密着性をこの方法で保証するために、基台502の粗面化された表面に係合して配置されている。
ボアホール716のような換気溝は、例えば図7(B)の溝710、図6(A)での溝602、図6(B)にあるような通路622等のような溝のくぼみに配置することができる。同様に、換気溝はくぼみから離れて導かれる。
ステップ904において、コーティンングは、準備されている、即ち、レリーフが備えられた基体に適用される。例えば、TPEのような合成材料、例えばPCUは、射出成形が適用される。材料は、レリーフの周囲に流れ込む。硬化後、コーティングは、隆起レリーフ構造を含むか又はそれぞれ凹凸形状のレリーフ構造を埋める。従って、コーティングは、特別な方法で基台に密着する。
