以下に、出願当初の特許請求の範囲に記載の事項を、そのまま、付記しておく。
[1]人工膝関節における立脚期緩衝の制御方法であって、前記人工膝関節は、旋回軸線(4)を中心として相互に旋回可能に締結されている上部(1)及び下部(2)、並びに前記上部(1)と前記下部(2)との間に設けられた抵抗部(6)を有し、前記抵抗部(6)は、緩衝抵抗(F D )を変化させる調整器(7)と、前記調整器(7)と結合され少なくとも1つのセンサー(9)に接続された制御装置(8)とを有し、調整がセンサー情報に基づいて実行される制御方法において、
立脚期末までの立脚期屈曲時、膝角度(α)が前記少なくとも1つのセンサー(9)によって検出されることと、屈曲緩衝(F D )が、所定の最大膝角度(α max )が到達されたときに更なる屈曲が回避されるように初期屈曲緩衝(F DI )より高いレベル(F Dmax )に増加させられることとを特徴とする、制御方法。
[2]前記屈曲緩衝(F D )が、最大膝角度(α max )が到達されたときのレベル(F Dmax )で維持されることを特徴とする、[1]に記載の方法。
[3]前記屈曲緩衝(F D )が、初期ヒール・ストライク中に一定に保持され、前記屈曲緩衝(F D )が、荷重に応じて増加させられることを特徴とする、[1]又は[2]に記載の方法。
[4]前記下部(2)の、遠位の回旋点を中心とする前方向回転が検出されることと、前記最大膝角度(α max )が到達された後に継続する前方向回転がある場合、前記屈曲緩衝(F D )が減少させられることとを特徴とする、[1]〜[3]の何れか一項に記載の方法。
[5]前記屈曲緩衝(F D )が、前記前方向回転の所定範囲を超過した場合及び/又は膝角度(α)が減少する場合に、減少させられることを特徴とする、[1]〜[4]の何れか一項に記載の方法。
[6]前記屈曲緩衝(F D )が、前記初期立脚期屈曲緩衝(F DI )又はそれより高い値まで減少させられることを特徴とする、[4]又は[5]に記載の方法。
[7]前記屈曲緩衝(F D )が、所定の最大膝角度(α)が到達されかつ下部(2)が相対的な前方向回転をした場合に減少させられることを特徴とする、[1]〜[6]の何れか一項に記載の方法。
[8]前記最大膝角度(α max )が、7度〜12度又は9度〜11度の範囲から選択され決定されることを特徴とする、[1]〜[7]の何れか一項に記載の方法。
