Abstract
【解決手段】可撓性要素は、第1の終端部10、第2の終端部20、およびその間に延在する基本的に矩形の断面を有するループ状に形成された平板なロッドの形状の部分を有し、ループが、接続軸Zに沿って第1の終端部10の円錐部から第2の終端部20の円錐部12まで、接続軸Zの両側に交互に延在して可撓性部分30を形成する。
【選択図】図9
Description
る場合と比較して利用可能な空間が著しく少ない、頸椎に適用する場合に関して重要である。さらに、広範囲の弾性特性が達成され得るので、異なる要件に対して容易に形状が適合され得る。
本発明の第1の実施例が、図1および図2を参照して下記に説明される。
図4および図5に示される第2の実施例が第1の実施例と異なるのは、基本的に可撓性部分の形状のみである。第2の実施例において、可撓性部分30′は、第1の実施例と同様に、ループ状に形成された平板なロッド32′の形状に形成される。ループの形状が第1の実施例における形状と異なるのは、洞穴状形状ではなくループ状または蛇行する形状が与えられ、側面図において、ループバルジ31′が、滴型の自由領域35′を囲む、より膨らんだ形状を有することのみである。この実施例において、隣接する2つのループバルジ31′aおよび31′bの側面36′aおよび36′bは、第1の実施例と比較して、互いに小さな距離しか有さない。
図6および図7に示される第3の実施例は、以下の点で第2の実施例と異なる。すなわち、隣接するループバルジ31″aおよび31″b間において、可撓性部分30″は、ループバルジ31″bと一体的に形成される追加的な37″bを有し、接続軸Zの反対側に
おいては、ループバルジ31″cおよび31″d間において、ループバルジ31″dと一体的に形成される追加的な37″dを有する。
図8に示される第4の実施例において、可撓性部分130がループ状に形成された平板なロッド132のループバルジ131の蛇行形状は、図4および図5に示される第2の実施例と比較してさらにより顕著である。この強調された蛇行形状によって、平板なロッド132は、2つのループバルジ131が横に並んで位置するよう接続軸Z方向で見た場合、可撓性部分130の中間においてS字型の形状を有する。
たとえば、可撓性部分の断面形状をさらに変形すること、またはロッドの延在方向において断面形状をさらに変形することが可能である。また、第1および第2の終端部は変形された形状を有してもよく、または、必ずしも可撓性部分と一体的に形成される必要はない。
