(EN) DEVICE FOR CORRECTING SCOLIOSIS AND CONTROLLING VERTEBRAL ARTHRODESIS
(FR) DISPOSITIF DE CORRECTION DE LA SCOLIOSE ET DE LUTTE CONTRE L'ARTHRODESE DES VERTEBRES
Abrégé
(EN)
The present invention relates to a device for correcting scoliosis, comprising a pair of distraction rods (2, 3) and a member (4) for linking the distraction rods provided with a means (8) for guiding each of the rods relative to each other inside said linking member. Said device also comprises at least one member (6) for suspending the distraction rods (2, 3) and is capable of imparting flexibility to and exerting a longitudinal preload on the rods so as to increase comfort and prevent the arthrodesis of the vertebrae of the spine of a patient fitted with the correction device. Said device finally comprises a structure for cushioning and translatably locking the distraction rods into the connection member. Said structure is only operative when compressive stresses of the spine of a patient are applied to the distraction rods (2, 3) so as to absorb and counter said compressive stresses and increase the comfort of the patient while preventing the arthrodesis of the spinal vertebrae of a patient.
(FR)
La présente invention concerne un dispositif de correction de la scoliose, comportant un couple de tiges (2, 3) de distraction, et un organe de liaison (4) des tiges de distraction, muni de moyens de guidage (8) de chacune des tiges l'une par rapport à l'autre à l'intérieur dudit organe de liaison. Ce dispositif comporte en outre au moins un organe de suspension (6) des tiges de distraction (2, 3) apte à conférer une souplesse et exercer une précharge longitudinale sur les tiges pour augmenter le confort et éviter l'arthrodèse des vertèbres du rachis d'un patient instrumenté du dispositif de correction. Il comporte enfin une structure d'amortissement et de blocage des tiges de distraction en translation dans l'organe de liaison, ladite structure étant active uniquement lors d'efforts de compression du rachis d'un patient sur les tiges de distraction (2, 3) de façon à absorber et s'opposer aux dits efforts de compression et augmenter le confort du patient en évitant l'arthrodèse des vertèbres du rachis d'un patient
