Title (EN) ARTICULATING TOGGLE BOLT BONE SCREW
(FR) VIS OSSEUSE COMBINEE A UN BOULON A AILETTES ARTICULE
Abstract:
(EN) An articulation toggle bolt bone screw for use in surgical implants having particular usefulness in the stabilization of the human spine by fixation of vertebra. The apparatus employs a self-tapping anchoring screw having a ball joint socket for receipt of a rotatable threaded bolt. The ball joint allows angular placement of the bolt which is secured into position by an attachment nut coupling directly to the anchoring screw. An upper surface of the attaching nut is rounded allowing engagement of component devices. A rod clamp is disclosed for use in combination with the device providing attachment to support rods and serving to bias the bolt into a permanent fixed position upon attachment. An alternative embodiment is disclosed of the rod clamp providing a single support rod attachment system.
(FR) L'invention concerne une vis osseuse combinée avec un boulon à ailettes à articulation destinée à être utilisée dans des implants chirurgicaux, particulièrement utile pour la stabilisation de la colonne vertébrale chez l'homme par la fixation de vertèbres. L'appareil utilise une vis d'ancrage autotaraudeuse présentant un support de joint sphérique destiné à recevoir un boulon fileté rotatif. Le joint permet de placer le boulon de manière angulaire. Le boulon est immobilisé par un écrou de fixation accouplé directement à la vis d'ancrage. Une surface supérieure de l'écrou de fixation est arrondie ce qui permet l'accouplement d'éléments constitutifs. L'invention concerne également un élément de blocage pour tige combiné avec le dispositif de fixation aux tiges de support et servant à placer le boulon dans une position permanente et fixe au moment de sa fixation. Selon une variante, l'élément de blocage pour tige comporte un seul système de fixation à la tige support.
