Description
Claims (6)
- 屈曲および/または湾曲した外套面と、この外套面上に存するねじ山を備えた領域とを有する自己切削型ねじ込み体であって、そのねじ山の歯のねじ山歯断面形状は前記ねじ込み体の仮想軸から離れるよう延在し、前記ねじ山は傾斜されたまたはねじられた少なくとも2つの切削フルートによって分割されており、前記切削フルートは前記ねじ込み体の前記仮想軸に対して交互に正の角度および負の角度を有するように延びるので、切削フルートとねじ山歯の側面との間に形成される切刃が、前記ねじ山歯の一方の側面上または他方の側面上に交互に偏倚させられていることを特徴とする、ねじ込み体。
- 前記ねじ山歯断面形状は、前記ねじ込み体の前記仮想軸に対して垂直に方向付けられていることを特徴とする、請求項1に記載のねじ込み体。
- 前記切刃は一連のねじ山の峰のつながりから偏倚させられており、すなわち、反対側に存するねじ山歯の側面は互いに整列しているが、ねじ山片の切刃はねじ込み方向に先行するねじ山の終端に関して一方側へ偏倚していることを特徴とする、請求項1または2に記載のねじ込み体。
- 各ねじ山歯を包む複数の表面は、ネジ表面からの複数の切抜であることを特徴とする、請求項1から3のいずれか1つに記載のねじ込み体。
- 各ねじ山歯を包む3つの表面のうちの少なくとも1つは、削り面の後側に逃げ角を形成することを特徴とする、請求項1から3のいずれか1つに記載のねじ込み体。
- 人工股関節寛骨臼カップ、人工肩関節の一部、大腿骨頸部ネジ、骨ネジ、または歯インプラントとして実現されることを特徴とする、請求項1から5のいずれか1つに記載のねじ込み体。
