前記機械的な圧縮装置(4)は、使用の際に骨組織の孔(15)内に当該装置を導入すると、この圧縮装置の第1の部分(2)の第2の部分(5;30)に対する相対的な動きを誘起して、この装置の外側表面の少なくとも一部と、隣接する前記孔の内側表面との間の少なくとも一つの空間(16)の容積(V)が減少し、それによって前記粒状体(18)を圧縮するように構成されている組立体において、
前記粒状体(18)は、骨および組織が前記集合体(17)の内部へ成長することができるようなスポンジ状の構造を有していることを特徴とする組立体。 - 前記集合体(17)が当該組立体(1)の外側表面上に供給され、かつ前記機械的な圧縮装置(4)は、前記外側表面に対して実質的に垂直な方向において前記容積を減少させるように構成されていることを特徴とする請求項1に記載の組立体。
- 前記圧縮装置(4)は、少なくとも前記第1の部分(2)の前記第2の部分(5)に対する回転により、粒状体を含む前記集合体(17)を圧縮するように構成されていることを特徴とする請求項1または2に記載の組立体。
- 前記第1の部分(2)が、前記空間(16)の前記容積(V)を減少させるためのリブおよびカム(8)のうちの少なくとも一つを有しており、それらは第1の状態においては第1の範囲で前記第2の部分(5)の内側に囲まれるとともに、第2の状態においてはより小さな範囲で前記第2の部分(5)の内側に囲まれ、使用の際に、前記第1の部分(2)の前記第2の部分(5)に対する前記第1の状態から前記第2の状態への回転により前記空間(16)の前記容積(V)が減少し、それによって前記集合体(17)を圧縮するようになっていることを特徴とする請求項3に記載の組立体。
- 前記第1の部分(2)が、前記空間の前記容積(V)を減少させるためのリブおよび指状部分(38)のうちの少なくとも一つを有するとともに前記第2の部分(30)がスカート(31)を有しており、前記スカートは、第1の状態においては第1の範囲で前記第1の部分(2)の内側に囲まれるとともに、第2の状態においてはより大きい範囲で前記第2の部分(5)の内側に囲まれ、使用の際に、前記第2の部分の前記第1の部分に対する前記第1の状態から前記第2の状態への並進により前記空間の前記容積(V)が減少し、それによって前記集合体(17)を圧縮するようになっていることを特徴とする請求項1または2に記載した組立体。
- 前記圧縮装置(4)は、少なくとも前記粒状体(18)の集合体(17)を圧縮するためにそれに沿って圧縮手段が設けられている長手方向範囲を有するように構成されており、前記圧縮手段は、前記長手方向範囲に沿って圧縮率を変化させるように構成されていることを特徴とする請求項1乃至5のいずれかに記載の組立体。
- 前記装置(4)は、長手方向に間隔を開けて配置された第1および第2の端部を有しており、前記圧縮手段は、使用の際に、前記第2の端部の方向において圧縮率の減少をもたらすように構成されていることを特徴とする請求項1乃至6のいずれかに記載した組立体。
- 前記集合体が、2つの異なる硬度の粒状体を少なくとも含んでいることを特徴とする請求項1乃至7のいずれかに記載した組立体。
- 前記集合体が、少なくとも2つの異なる寸法の粒状体を含んでいることを特徴とする請求項1乃至8のいずれかに記載した組立体。
- 前記集合体(17)は、四塩化チタンとの反応によって得られた粒状体を含んでいることを特徴とする請求項1乃至9のいずれかに記載した組立体。
- 前記圧縮手段(4) は、使用の際に、前記人工関節がその内部に固定される孔の開口近傍の肩部に、この肩部から離れた位置におけるよりも堅い固定をもたらすように構成され、前記粒状体(18)の内部への骨組織の成長を誘起する微小な運動を得るために、前記肩部より下方における前記人工関節の曲げが可能となっていることを特徴とする請求項1乃至10のいずれかに記載の組立体。
- ステム(2)のような固定部分を備える人工関節であって、
前記固定部分(2)の少なくとも一部に、圧縮手段(4)と、生体適合材料の粒状体(18)を少なくとも含む集合体(17)とが設けられており、前記圧縮手段(4)は前記粒状体(18)を圧縮するように構成され、使用の際に、前記固定部分(2)が骨組織の孔(15)に導入されたときに前記圧縮手段が操作可能である人工関節において、
前記粒状体(18)は、スポンジ状の構造を有し、前記圧縮手段(4)の上に供給され、および/または、その内側に封入され、使用の際、前記圧縮手段(4)の少なくとも一部を通過する、前記骨組織の孔の壁から前記粒状体(18)の内部への骨成長が可能となっていることを特徴とする人工関節。 - 骨組織の孔のような孔(15)の内部に固定する人工関節(3)を製造する方法であって、
前記人工関節に圧縮手段が設けられ、
前記圧縮手段(4)は、内部へ集合体が導入される少なくとも一つの空間を囲んでおり、
前記集合体(17)は、スポンジ状の構造を有した生体適合材料の粒状体(18)を少なくとも含んでおり、
