Description
駆動輪は、下側部に滑動可能に取り付けられるのが好ましい。制御カムは、駆動輪の回転中に、被駆動要素の支持セクションと滑動的に相互作用する。支持セクションは、高さ方向において制御カムに支持される。駆動輪の回転中に、制御カムと支持セクションの間で相対的な滑動運動が起こる。換言すれば、制御カムが、支持セクションの下を滑って通過する。これにより、支持セクションは、制御カムのピッチによって、高さ方向に押し上げられる。制御カムと支持セクションは、点状に、線に沿って、および/または表面にわたって、相互作用してもよい。制御カムは、一定のピッチを有してもよいし、または異なるピッチを有してもよい。被駆動要素は、上側部に堅固に接続されている。被駆動要素は、上側部と一体的に形成されているのが好ましい。被駆動要素は、上側部の下面に配置されるのが好ましい。滑動面は、上側部に形成され、上側部の上面を構成するのが好ましい。あるいは、滑動面は、上側部の上面に接続される別部品に形成されてもよい。下側部は、脛骨固定のために設けられる。使用中に、下側部の下面は、脛骨の近位端に直接固定されてもよい。あるいは、下側部は、直接脛骨に固定された脛骨トライアルプラトーなどに固定されてもよい。下側部および上側部はそれぞれ、1つまたは複数の部品で構成されてもよい。下側部および上側部はそれぞれ、板状の基本形状を有するのが好ましく、そのため、下側プレートおよび上側プレートと呼ばれることがある。第1の調節位置において、脛骨トライアルインプラントは、高さ方向に延びる全高を有し、これは、第2の調節位置における全高よりも小さい。したがって、第2の調節位置と比較すると、第1の調節位置では、滑動面が、高さ方向において下側部により近接した位置にある。
下記する項目は、出願当初の特許請求の範囲に記載されていた項目である。
