Description
人工くるぶしや人工足は周知である。例えば、下記特許文献1は、人の足に於ける3つの基本的な動作カテゴリを模倣する生体力学的くるぶしを開示している。平行な足底プレートおよび脚部支持板が、上方に延びる
柱により離間した状態で保持されている。脚部支持板は、球関節でこの柱に接合されている。板同士の間につる巻きばねを固定し、これにより、通常の筋肉制御を模倣して、足の前部分を柔軟に支持している。ばねと協働するこの球関節により、生体力学的くるぶしは、通常の人の足に於いて見られる内反―外反、足底の背屈−底屈および側方回転を模倣できるようにされている。
本発明の別の局面に於いて、前記くるぶし構成部材の前部は、前記くるぶし構成部材の後部より約5°〜約20°高い。
本発明の更に別の局面に於いて、前記義足はマイクロプロセッサー装置を備えている。
下記の図面の説明により、本装置は当業者にとって明白になるであろう。
図面の詳細な説明
図1〜図11は本発明に係るモジュール式義足を示す。本発明は解剖学に基づいたモジュール式義足である。本義足は解剖学的な足の運動生理学に基づいて設計された。特に、本義足の構造は、図1に示すような距骨下関節100を模倣することに重点を置いている。解剖学的に、脛骨が内側に回転すると、距骨下関節は外反する(回内する)。反対に、脛骨が外側に回転すると、距骨下関節は内反する(回外する)。このように、理論的には、距骨下関節は楕円状ヒンジとして機能する。
くるぶし構成部材は、かかと構成部材と前足構成部材との両方を接合することを可能にする効果的な形状と寸法を有する一体構造体である。
くるぶし構成部材205は、図2に示すように、人工器官の一部または仮義足(パイロン)220に接合してもよい。したがって、くるぶし構成部材は、図3〜図4および図8に示すように、人工器官の一部または仮義足に接合できるよう差込口、つまり開口部305を含んでいる。人工器官の一部への接合または仮義足への接合は、世界全体で使用されている内骨格または外骨格の人工装具システムを取付けるために最も一般的になされている2つの方法である。実施形態に於いて、差込口、つまり開口部305は、前足構成部材210およびかかと構成部材215が接合または装着される面と反対側にある、くるぶし構成部材205の表面にあってもよい。くるぶし構成部材は、少なくとも1つの接合部により、人工器官部分または仮義足に接合してもよい。この接合部は、ピン、ねじ、ボルト、軸、粘着性化合物、またはこれらの組合せであってもよいが、これらに限定されるわけではない。
前足構成部材210は、効果的な形状および寸法であればよい。実施形態に於いて、前足構成部材は、楕円形状、J字状、C字状、またはS字状であってもよい。
図2および図9に示すように、前足構成部材210の後部210bは、くるぶし構成部材205に接合されている。
C.前足クッション緩衝部
モジュール式義足の動作(外反および内反)は、図3〜図4に示すように、円形部の周囲に位置する前足クッション緩衝部310により制限または制御されてもよい。前足クッション緩衝部310は、効果的な形状および寸法であればよい。実施形態に於いて、前足クッション緩衝部はU字状または馬蹄状(図6D)であってもよく、これにより、前足クッション緩衝部を、前足構成部材210の後部210bの円形部510の周囲にしっかり固定または圧入することができる。
D.かかと構成部材
かかと構成部材は、効果的な形状および寸法であればよい。実施形態に於いて、かかと構成部材は、楕円形状、J字状、C字状、またはS字状であってもよい。
実施形態に於いて、本発明のモジュール式義足は、マイクロプロセッサーを含んでいてもよい。このマイクロプロセッサーは義足のいずれの構成部材内に設けてもよいが、前足構成部材または前足クッション緩衝部内部に設けることが好ましい。少なくとも1つのマイクロプロセッサー装置は、モジュール式義足を使用する人がどのように歩行するか監視(モニター)することができるようにしてもよい。
本発明の義足のモジュール方式は利点が多い。例えば、1つの前足クッション緩衝部を、1つまたは複数の異なる特性(例えば、異なる材質、異なる厚み、異なる密度、異なる形状)を持つ別の前足クッション緩衝部に取り替えて、運動度または圧縮度を変更するようにしてもよい。更に、単一のくるぶし構成部材に対して、異なる前足構成部材および異なるかかと構成部材を入れ替えるようにしてもよい。
本発明は特定の実施例や別の実施形態に関して説明を行ってきたが、本発明はこれらの実施形態に限定されることはない。本発明が包含する別の実施形態や実施例や変更例は、特に上記教示に鑑み、当業者によりなされることができる。
