Title (EN) SPINAL IMPLANT
(FR) IMPLANT SPINAL
(JA) 脊椎インプラント
Abstract:
(EN) The objective of the present invention is to provide a spinal implant in which a compact housing can be used in common regardless of the bone screw diameter, and which has excellent assembly properties. This spinal implant 1 is provided with a screw head portion retaining member 4, a housing 3 and an insert 5. The screw head portion retaining member 4 includes a tubular portion 21 which is elastically deformable in a radial direction and in which is formed a supporting portion 27 which supports a screw head portion 2b from the lower side thereof. The housing 3 accommodates the screw head portion retaining member 4 in a state in which the screw head portion 2b is being retained thereby. The screw head portion retaining member 4 also has an elastically deformable portion 22 which is capable of deforming elastically in the radial direction of the tubular portion 21 in such a way that an engaging portion 25 engages with an inner peripheral surface side of the housing 3.
(FR) L'objectif de la présente invention est de réaliser un implant spinal dans lequel un logement compact peut être utilisé en commun indépendamment du diamètre de la vis à os, et dont les propriétés d'assemblage sont excellentes. Cet implant spinal (1) comporte un organe de rétention (4) de partie de tête de vis, un logement (3) et une insertion (5). Cet organe de rétention (4) de partie de tête de vis inclut une partie tubulaire (21) qui est déformable élastiquement dans une direction radiale et dans laquelle est formée une partie de support (27) qui supporte une partie de tête de vis (2b) depuis son côté inférieur. Le logement (3) contient l'organe de rétention (4) de partie de tête de vis dans un état où la partie de tête de vis (2b) est ainsi retenue. L'organe de rétention (4) de partie de tête de vis comporte également une partie élastiquement déformable (22) qui peut se déformer élastiquement dans la direction radiale de la partie tubulaire (21) de telle manière qu'une partie de prise (25) entre en prise avec un côté de surface périphérique intérieure du logement (3).
(JA) 小型化されたハウジングを骨スクリューの径によらず共通化でき、且つ組立性に優れた脊椎インプラントを提供する。 脊椎インプラント1は、スクリュー頭部保持部材4とハウジング3とインサート5とを備えている。スクリュー頭部保持部材4は、スクリュー頭部2bを下側から支持する支持部27が形成された径方向に弾性変形可能な筒状部21を有している。ハウジング3は、スクリュー頭部2bを保持した状態のスクリュー頭部保持部材4を収容する。スクリュー頭部保持部材4は、係合部25がハウジング3の内周面側に係合するように筒状部21の径方向に弾性変形可能な弾性変形部22を更に有している。
