Abstract
Description
本出願は、2013年3月5日出願の米国第13/785,434号及び2013年11月20日出願の同第14/085,318号の一部継続出願であり、これらは、2013年3月5日出願の米国特許出願第13/785,856号の一部継続出願であり、これは2012年7月27日出願の同第13/559,917号の一部継続出願であり、これは2011年10月6日出願の同第13/267,119号の一部継続出願であり、これは2011年9月16日出願の米国仮出願第61/535,726号の優先権を主張し、これらの全体の内容が、参照することにより組み込まれる。
本出願は、概して、整形外科的システムを対象とし、特にプレート及びスペーサを含むシステムを対象とする。
脊椎椎間板及び/または脊椎の椎体は、脱臼し得るか、または外傷、病気、変性疾患、もしくは長時間の摩耗に起因して損傷を与えられ得る。この脱臼または損傷による1つの結果は、慢性背部痛であり得る。いくつかの事例において、背部痛を和らげるために、椎間板は、除去され得、融着を助長するスペーサ等のインプラントに取って代えられ得る。1つ以上のスペーサを提供することに加えて、プレート固定システムは、融着過程の間、脊椎を更に安定させるために使用され得る。かかるプレート固定システムは、椎骨を互いに対して固着する位置で整合及び保持するための1つ以上のプレート及びねじを含み得る。
プレート固定システムに関する種々のシステム、装置、及び方法が提供される。いくつかの実施形態において、脊椎システムは、椎間腔中に挿入するためのスペーサ及びスペーサに当接するように構成されたプレートを備える。スペーサは、上部表面、下部表面、及び上部表面から下部表面の間に延在する開口を含み得、スペーサは、先細りの先端を更に含む。スペーサに当接するためのプレートは、プレート体、第1の骨ねじを受容するためのプレート体中に形成された第1の開口、第2の骨ねじを受容するためのプレート体中に形成された第2の開口、止めねじ、及びスペーサと係合するように構成されているプレート体から延在する一対の伸長部を含み得る。第1の開口は、上向きの方向に角度付けられ得るが、第2の開口は、下向きの方向に角度付けられ得る。止めねじは、第1及び第2の骨ねじの両方の抜けを防止するように構成され得、止めねじが、第1及び第2の骨ねじが止めねじを通り越して、第1及び第2の開口中に挿入され得る第1の位置と、第1及び第2の骨ねじが止めねじによって抜けを防止される、止めねじの回転後の第2の位置とを有する。第1の骨ねじは、プレート体中の第1の開口中に挿入するために提供され、第1の骨ねじは、第1の椎体中に挿入されるように構成されている。第2の骨ねじは、プレート体中の第2の開口中に挿入するために提供され、第2の骨ねじは、第1の椎体とは異なる第2の椎体中に挿入されるように構成されている。
図1A〜1Dは、いくつかの実施形態による、スペーサに連結される薄型プレートの異なる図面を例示する。
本出願は、概して、整形外科的システムを対象とし、特にプレート及びスペーサを含むシステムを対象とする。
