関連出願の相互参照
本出願は、2011年3月15日にファイルされた米国仮出願番号61/789,476号の優先権を主張し、その全体を参照することにより本明細書に援用される。
〔図面の簡単な説明〕
以下に記載する図面の説明は、本質的には単なる例に過ぎず、本明細書に説明する内容、それらの応用、またはそれらの適用を限定することを意図していない。図の全般において、対応する参照番号は類似または関連する部材および特徴を示している。以下の図の相対的な寸法は、一定の比率に縮小して描かれてはいない、ということに注意すべきである。
以下の詳細な説明は、ある特定の実施形態についてのものである。しかし、ここで記載される技術は多くの異なる方法にて適用され得る。
第2変形自在部518aおよび518bは、適合面外科用ガイド器具500の安全性および安定性をさらに提供するために、大腿骨512に取り付けられる。他の実施形態において、第2変形自在部518aおよび518bは、代わりに固定部であってもよい。例えば、骨(例えば、大腿骨)のモデルが、大腿骨512と要素518aおよび518bとの間の境界領域の正確性が非常に高い場合、固定部を代わりに用いてもよい。さらに、要素518aおよび518bは、固定または可変のいずれにおいても、患者特異的であってもよい。
的面のより多様な部位に取り付けられるように設計された変形自在部の点は、非常に可変である。これにより、表面の多様性にかかわらず、変形自在部を、解剖学的面の多様な部位に合わせることができる。
