前記張力部材の張力を調整するための調整手段を備え、該調整手段は、前記骨係合部材に対する前記張力部材の位置を調整するために前記張力部材と前記骨係合部材の間の螺合係合を有し、
前記人工靱帯が、結合手段を介して前記張力部材に連結され、該結合手段が、前記人工靭帯上に形成され、前記張力部材と係合する拡張部を有することを特徴とする人工関節。 - 前記人工靭帯は、前記第一骨係合部材の前記本体部に形成された陥凹部の内部に固着されていることを特徴とする、請求項1に記載の人工関節。
- 更に、第二骨係合部材を有し、前記人工靱帯の第2端が第二骨係合部材に連結されていることを特徴とする、請求項1〜2のいずれかに記載の人工関節。
- 前記偏倚部材が、スプリングまたは弾性部材から構成されていることを特徴とする、請求項1〜3のうちの一項に記載の人工関節。
- 前記偏倚手段は、その硬さが天然靭帯の硬さに近似していることを特徴としている、請求項1〜4のいずれかに記載の人工関節。
- 前記偏倚部材は、非線形の硬さ特性を有していることを特徴とする、請求項1〜5のいずれかに記載の人工関節。
- 前記拡張部は、前記人工靭帯に結わえられた結び目を有することを特徴とする、請求項1〜6のいずれかに記載の置換術用人工関節。
- 前記張力部材は、前記人工靭帯内の張力を調整し、少なくともその一部が前記骨係合部材の内部に収容されていることを特徴とする、請求項1〜7のいずれかに記載の人工関節。
