Description
Claims (9)
- 患者の二つの隣接する椎骨部(11)の間に挿入することが可能であり、それぞれ一つの部材(4,9)が各椎骨部(11)の方を向いている人工椎間板(1,8)であって、両方の部材(4,9)が、互いに向き合った成形部分(3)を有し、その成形部分によって、これらの部材(4,9)が、中間部材(2)と形状を合わせた形で接続されている椎間板において、
中間部材(2)が、リング状の閉じた形状をしており、そのリング形状の中心軸(7)に対して垂直な横断面が尖頭形、楕円形又は円形であり、そのリング形状の中心軸(7)を包含する面内における断面が中空の尖頭形、楕円形又は円形であり、
両方の部材(4,9)の互いに向き合った成形部分(3)が、互いに逆向きに湾曲した凹状に形成されており、その凹状に形成された部分の直径Dが、中間部材(2)の尖頭形、楕円形又は円形の横断面の直径dよりも大きくなっており、
そのため、これらの部材(4,9)は、中間部材(2)を用いて、制限された形で関節形式により互いに接続されており、その中間部材を介して、捻り回転モーメントと剪断力の両方を伝達することが可能であることを特徴とする椎間板。 - 成形部分(3)が、切欠きを有することを特徴とする請求項1に記載の椎間板(1,8)。
- 成形部分(3)が、摩擦に対して最適な表面特性を有することを特徴とする請求項1又は2に記載の椎間板(1,8)。
- 成形部分(3)が、両方の部材(4,9)と中間部材(2)との間に摩擦を生成するために、少なくとも部分的に摩擦を高める表面構造又は粗さを有することを特徴とする請求項1から3までのいずれか一つに記載の椎間板(1,8)。
- 中間部材(2)は、そのリング形状の中心軸(7)の方向に沿って、少なくとも部分的に異なった横断面(括れ(6))を有し、それらの横断面が、それに対応して実現された成形部分(3)と協力して作用することを特徴とする請求項1に記載の椎間板(1,8)。
- 当該の中間部材(2)の横断面が、患者の矢状面、前頭面、水平面の中の一つ以上において部分的に広がっていることを特徴とする請求項1から5までのいずれか一つに記載の椎間板(1,8)。
- 中間部材(2)が、少なくとも部分的にポリマー、特にポリエチレンから構成されていることを特徴とする請求項1から6までのいずれか一つに記載の椎間板(1,8)。
- 部材(4,9)は、その椎骨部(11)の方を向いた側に、骨格に固定するための固定用のスパイク(5)又は部品を備えていることを特徴とする請求項1から7までのいずれか一つに記載の椎間板(1,8)。
- 部材(4,9)は、その椎骨部(11)の方を向いた側における骨格に固定するための固定用のスパイク(5)又は部品が、チタン又はその他の生体適合性を持つ材料でコーティングされていることを特徴とする請求項1から8までのいずれか一つに記載の椎間板(1,8)。
