The present invention is directed to a spinal support coupling device (10) comprised of first and second radial frames (44A and 44B), each pivotably coupled to a center pivot hinge (30). A traveling arm (20) is provided, coupled to the first and second radial frames (44A and 44B) at the center pivot hinge (30). The traveling arm (20) is configured to rotate with respect to the first and second radial frames (44A and 44B) around the center pivot hinge (30). A coupling rod (80) is attached to the traveling arm (20) and configured to connect a first and a second surgical screw (60A and 60B), placed into a patient. The first and second radial frames (44A and 4413) are configured to retain corresponding first and second extension rods (64A and 64B), extending away from the top of the first and second surgical screws (60A and 60B).
Cette invention a trait à un dispositif de couplage de support vertébral (10) comprenant deux éléments d'ossature radiaux (44A et 44B), couplés pivotant à une articulation centrale à pivot (30). Le dispositif comporte également un bras mobile (20), couplé aux deux éléments d'ossature (44A et 44B), au niveau de l'articulation centrale à pivot (30).Ce bras mobile (20) est conçu pour entrer en rotation relativement aux deux éléments d'ossature (44A et 44B), autour de l'articulation centrale à pivot (30). Une tige de couplage (80), qui est fixée au bras mobile (20), est conçue pour venir se connecter à deux vis chirurgicales (60A et 60B), implantées dans le corps d'un patient. Les deux éléments d'ossature (44A et 44B) sont conçus pour retenir deux tiges d'allongement (64A et 64B), partant de la partie supérieure des deux vis chirurgicales (60A et 60B).
