Abstract
【解決手段】外部固定コンポーネントは3つの要素からなる。第一捕捉部材10はクランプ部品である。この第一捕捉部材10は中央回転部材30に連結され、中央回転部材30は第二のクランプ部品である第二捕捉部材20に連結される。適応する中央固定ねじとシャフトを使用すれば、別の捕捉部材を中央回転部材30にも、従来のクランプ部品にも連結して用いることができる。
【選択図】図1
Description
外部固定コンポーネントは、外部固定システムの第一及び第二要素を独立して捕捉するように構成された2つの捕捉部材を含む。回転部材が2つの捕捉部材の間に双方に連結されて設けられ、その連結によって2つの捕捉部材が互いに対して3つの軸の周りに回転可能となる。各捕捉部材は各捕捉部材を貫通して延び、結合した捕捉部材の長手方向軸を定める中央固定ねじを有する。回転部材は2つの回転阻止部を含み、各阻止部には、捕捉部材のうちの一つの相補的接触面と当接するように構成された1つの接触面が設けられ、各阻止部にはさらに内側円筒状面を有する前記接触面と反対側の面が設けられる。回転部材は対応する回転阻止部の内側円筒状面の相補的面として回転面を形成する中央ディスク要素を含み、2つのナットを含み、各ナットは対応する捕捉部材の1つの固定ねじに連結されて、捕捉部材の各固定ねじは対応する回転阻止部を貫通して延び、各捕捉部材をそれぞれ固定するために対応するナットと係合する。
