Description
この型のスペーサはDE 196 22 827 A1から公知である。第1の部材内に導かれる第2の部材は、その表面上のねじ山と、ねじ山にねじ込まれる止めリングとを含む。第1の部材は第2の部材上へと嵌められ、両方の部材はリングの上にねじ込まれることによって形成される止め具まで互いに対して押込まれる。2つの脊椎骨間に挿入した後、スペーサを延ばすために第1のスリーブの方へリングをねじ込むことによって最終的な長さが調節される。最終的な位置において、両方の部材が締付けねじを用いて互いに対して締められる。スペーサの両方の自由端には隣接する脊椎骨へと食込むためのブレードを有した面が設けられる。長手軸の周りに止めリングを回転させる必要のために、あるトルクが両方の部材に与えられ、これは、スペーサを挿入する際に与えられるトルクによって、部材の自由端のブレードが隣接する脊椎骨を傷つけるという危険を引き起こす。動作のために利用可能な空間が限られているので回転は非常に困難である。
この発明の目的は、先行技術の欠点を回避するように、長さを調節するための回転力または運動が必要とされない上述の型のスペーサを提供することである。
この目的は請求項1に記載のスペーサによって達成される。
クレーム2に記載のラチェットを用いて、スペーサを挿入する外科医は、その理想的な長さで最終的にスペーサを固定する前に、異なる明らかに理想的な位置の間で前後に移動することができる。
請求項10に記載のスペーサ部材の対応する端縁部分の形態は、外科医がこの可変スペーサの端面を角度的に調節できるという利点を有する。
この発明のさらなる特徴および利点は図を参照すると実施例の説明から明らかとなるであろう。
図1は、スペーサの一方の部材の側面図である。
図2は、図1に示す部材の平面図である。
図3は、スペーサの他方の部材の側面図である。
図4は、図3に示す部材の底面図である。
図5は、互いに挿入された後の両方の部材の側面図である。
図6は、工具が挿入された図5の線A−Aに沿う断面図である。
図7は、固定ねじの側面図である。
図8は、固定ねじの平面図である。
図9は、自由端が角度調節されたスペーサの側面図である。
図10は、2つの脊椎骨間に挿入された工具付スペーサを示す。
図11は、固定ねじが正しい長さに調節されたスペーサを示す。
図12は、挿入された固定ねじの拡大図である。
図13は、端部プレートが適所にあるスペーサを示す。
図14は、端部プレートの一方の平面図である。
図5および図6に最もよく示すように、スペーサは第1の部材を形成する外部スリーブ1と第2の部材を形成する内部スリーブ2とを含む。
図3、図4および図6に最もよく示すように、外部スリーブ1はスリーブ長さの半分よりも大きい大きさだけ第1の自由端4からその他方の自由端の方へ延びる第1のジャケット部分3を有する。このジャケット部分は第1の内径を有する。続く第2のジャケット部分5において、ジャケット壁がその内側で薄くされ、第1の内径よりも大きい第2の内径を有する。図3に最もよく示すように、第1のジャケット部分はスリーブの軸方向に一方が他の上方に位置決めされた2つのねじ孔6および7を含む。さらに、第1のジャケット部分は複数の開口8を有し、開口はジャケット部分全体にかけて配分され、ジャケットを通って延びる孔として形成される。第2のジャケット部分5は菱形の開口10、11を有し、その長手対角線は図3に示す態様でスリーブ軸9と平行に延びる。このような菱形開口10の第1のグループが端縁に隣接して円周方向に延び、この第1のグループには、第1の自由端4へ向かう方向で、菱形開口の第2のグループ11が従い、それによって第2のグループ11は軸方向に菱形の高さの半分だけ第1のグループからずらされる。これによって、間の鋭角と菱形の長手対角線との等角とを含む交差するウェブ状ストリップ12、13の網目が生じる。菱形とそれを規定するストリップとが円周方向に常に整数個の菱形を得るような大きさにされる。このように形成された端縁はウェブ状ストリップによって形成される先の尖った部分とその間の切込み22とを含む。
図1、図2および図6に最もよく示すように、第2の部材は第1の外殻部分15を含み、第1の外殻部分15は第1の外殻部分の第1の自由端14に隣接する第1の外径を有する。図示する実施例では、第1の外殻部分は軸長の3分の2をわずかに超えて延び、それには、同じ外径を有し、かつ第2の自由端まで延びる第2の外殻部分16が従う。外径は、図6に最もよく示す態様で外部スリーブの第1のジャケット部分3において内部スリーブが摺動して導かれるように選択される。内部スリーブの第1の自由端14にはカラー17が設けられ、カラー17は、第1の外殻部分の直径と外部スリーブの第1の内径よりも大きく、外部スリーブの第2のジャケット部分5の内径よりも小さい直径を有する。
第1の外殻部分15は、スリーブ軸9と平行な方向に並んで形成され、半径よりも小さい深さを有する複数の球形状の凹部18を含む。図1に最もよく示すように、2つの隣接する凹部の間隔またはピッチは球形状の凹部を規定する端縁の直径よりも小さい。その結果、2つの隣接する凹部間の境界線19は凹部に固有の端縁20よりも低い。凹部18の領域は第1の外殻部分15のほぼ全長に沿って延びる。スリーブを通って延びる孔として形成される開口21は、第1の外殻部分の表面全体にわたって、開口8に対応する態様で設けられる。第2の外殻部分16は第1のスリーブの第2のジャケット部分に対応する態様で形成され、間にストリップ12、13を有する対応して構成された菱形開口10、11を含む。スリーブの自由端において、ストリップは互いに向かって収束し、間にある突出し、比較的鋭い先の尖った部分でそれぞれの切込み22を規定する。
スペーサを組立てるために、内部スリーブ2は図5および図6に最もよく示す態様でその第2のジャケット部分5の側から外部スリーブ1へと押込まれる。最大の押込み深さが、2つのジャケット部分3および5の間に形成される内部ショルダと接触するカラー17によって規定される。
工具23は、スペーサが2つの隣接する脊椎骨の間に挿入され、図10および図11に最もよく示す態様で所望の長さに拡張され、固定されることを可能とするために設けられる。工具23は、その一方端に設けられ、2つのねじ孔6、7の内部ねじ山に適合する外部ねじ山を有する。外部ねじ山には、工具をねじ孔6または7にねじ込む際の止め部分を形成する肩部24が続く。ボール25が外部ねじ山に隣接して工具の面に取付けられ、概略的に示す内部ねじによって矢印Fの方向で外部に弾力的に偏らされる。ボールの直径は、ボールが球形状部分にちょうど適合するように球状凹部18の直径と等しいかそれよりもわずかに小さい。スペーサのこの組立状態において、両方のスリーブが図5および図9に最もよく示すように互いに対して変位可能であり、最大の長さまで拡張可能である。ばねで偏位させられるボール25がラチェットの態様で球形状の凹部18と協力し、それによって、延長部が2つまたは複数の凹部の間隔によって変更され得る。2つのスリーブは適切な押し広げ工具を与えることによって動作中に延ばされる。
図7および図8に示す固定ねじ27はねじ山6、7と協力するような大きさの外径を有する。図7および図12に最もよく示すように、球状部分28が固定ねじの端部面の中央に設けられる。球状部分28の大きさは工具23の端部面から自由に突出する球状部分のそれに対応する。反対の端部面はスクリュードライバの係合のための六角形の穴を有する。
動作において、図10に従って挿入されるスペーサが図11に示す最適な長さにはじめに調節され、工具23によって保持される。その後、図12に示すような固定ねじ27が第2のねじ孔へとしっかり締められて、互いに対して適切な位置に2つのスリーブを固く固定する。工具23のねじをゆるめた後、対応のねじ27が第2のねじ孔に挿入されてさらなる固定を与える。
図9に示すように、菱形開口を有する部分5および16が、適切な切断工具を用いて脊椎骨と係合する端縁部分の傾斜角が調節され、同時に、隣接する脊椎骨と係合するための端縁における切込みおよび先の尖った部分が形成される可能性を与える。
図13および図14に示すように、端部プレート29および30は端部プレートを突出する先の尖った部分32、33へとはめるための孔31と食込み(ingrowing)を高めるための開口34を有する。
上述の実施例において、2つのスリーブが円筒形で形成される。しかしながら、それらは他の断面形状を有してもよく、断面形状は接続されるべき部分によって規定される。
