Abstract
【解決手段】 完成した後部の安定した人工膝、特に試行用人工膝、の脛骨挿入部は、大腿部の1つまたは幾つかの関節丘と共に、1つまたは幾つかの凹状の接触面が形成される上部のベース部(5)と、ベース部から、特に直角に突出するように作られた脛骨スタッド(6)とを有し、脛骨スタッドは、ベース部から取り外し可能であり、ベース部の厚さよりも大きな長さで、ベース部の下面から延びるピン(12)を有し、ベース部は、上面と対向する、ベース部より下面から下方に、脛骨スタッドが突出するように貫通すべく作られた孔(9)を有している。

Claims (8)
- 脛骨盤と、大腿部と、大腿部および脛骨部の間に挿入された脛骨挿入部とを有し、取付け手段によって脛骨盤に係合されて、大腿部の1つまたは複数個の関節丘によって形成される1つまたは複数個の凹状の接触面から上部にベース部が作られた脛骨部、および
ベース部に対して特に直角に突出し、ベース部から取り外しできる脛骨スタッド部、
を有する後部の安定した完成された人工膝において、
前記脛骨スタッド部は、脛骨スタッド部下面から、ベース部の厚さよりも長さが長くなっているピンを有し、
前記ベース部は、脛骨部が延入する交差孔を有しているので、脛骨部が、ピン軸心を取り囲むベース部に関してスタッド部が回転できないように構成された、ベース部の上面と対向した下面から突出していることを特徴とする人工膝。 - 前記脛骨スタッドは、特に平坦で、非円形の、特に長方形または正方形で、ピンが突出するように台座が作られており、前記脛骨挿入部は、ピン軸心周りの回転を阻止するために、台座に対して補足的な寸法と形状の上面に空所を有することを特徴とする請求項1に記載の人工膝。
- 前記ピンは、形状が筒状で、特に円形であり、前記孔は、ピンに対して補足的な形状であることを特徴とする請求項1に記載の人工膝。
- 前記ピンを孔内に錠止するのを容易にするために、Oリングウエッジが該ピンにねじ着されることを特徴とする請求項1に記載の人工膝。
- 形状が試行であることを特徴とする請求項1に記載の人工膝。
- 異なった寸法であって、それぞれ大腿部の1つ以上の関節丘と一緒に1つ以上の凹状の接触面をその上部に有する複数個のベース部と、
長さが各ベース部の厚さよりも長くなっている下面から突出するピンを有する脛骨スタッド部と、を有し、
各ベース部は、スタッド部が、各ベース部に対し、かつピンの軸心周りに回転できないような具合に、高い面と対向して構成された各ベース部の下面から突出するように脛骨スタッド部が貫通する交差孔を有することを特徴とする請求項5に記載の人工膝のための脛骨挿入部の集合体。 - 前記脛骨スタッド部は、形状が特に平坦で、かつ非円形で、特にほぼ長方形または正方形であって、ピンが突出しているベース部台座を有し、各ベース部は、前記脛骨挿入部は、ピン軸心周りの回転を阻止するために、台座に対して補足的な寸法と形状の上面に空所を有することを特徴とする請求項6に記載の脛骨挿入部の集合体。
- 前記ピンは、形状が筒状で、特に円形であり、前記孔は、ピンに対して補足的な形状であることを特徴とする請求項6に記載の脛骨挿入部の集合体。
