Abstract
【解決手段】 本発明では、椎骨(1)の各椎弓根(2)に円柱状の通路(7)を穿孔し、通路(7)内から各椎弓根を通る環状椎弓根の切削部(骨切断部)(11)を作成し、前記椎弓根の切削部(11)を伸長させて脊柱管(3)を広げた前記通路(7)にインプラント(16)を挿入することで前記椎弓根の切削部(11)を離し、さらに各椎弓根の切削部(11)を固定することによって脊椎(3)管を拡張し、前記脊柱管(3)が拡張した状態で前記椎骨(1)が治癒するようにする。前記インプラント(16)は、外側のスリーブ(17)、内側のボルト(18)、および拡張可能フランジ(21)を含む。前記外側のスリーブ(17)は上部(19)および下部(20)を含み、前記下部(20)に接続し、前記上部(19)の中に収納された前記拡張可能フランジ(21)を伴う。前記内側のボルト(18)を回転させることにより前記外側のスリーブの前記上部と下部(19、20)が離れ、前記椎弓根の切削部(11)が広がり、前記拡張可能フランジ(21)が放射状に拡張し、広がった椎弓根の切削部(11)を安定化して前記脊柱管(3)拡張を達成する。
Description
本出願は、2000年9月11日付け米国特許出願第09/659,180号、発明の名称"A Method and Implant for Expanding a Spianl Canal"、の一部継続出願(CIP)であり、この参照によりその全体が本明細書に組み込まれるものである。
(1)正常な脊髄の構造が取り除かれないため、正常な筋肉の付着部が維持される。
(2)脊髄が不安定化する可能性が低い。
(3)脊髄神経を触診することが少ない。
(4)脊髄神経周辺の瘢痕化が少ない。
(5)脊髄の除圧がより完全となる。
(6)手術がより迅速且つ安全に行うことができ、失血が少ない。
(7)脊柱管の拡張状態が永続的で、脊髄狭窄症の再発を予防できる。
(8)前記処置を経皮的に、非常に小さな切開で達成することができる。
Claims (2)
- 脊柱管を拡張する方法であって、
少なくとも1箇所で前記脊柱管まで椎骨を切削する工程と、
前記脊柱管を拡張するために各椎骨の切削部を広げる工程と、
前記椎骨を前記拡張した脊柱管と共に治癒するように各分かれた椎骨の切削部を固定する工程と、を有する。 - 脊柱管を拡張するためのインプラントであって、
外側のスリーブと、
前記外側のスリーブと係合した内側のボルトと、を有し、
前記外側のスリーブに対する前記内側のボルトの動作によって、椎骨の切削部を広げ、前記脊柱管を拡張するものである。
