(FR) COMPRESSEUR/DISTRACTEUR À PLUSIEURS NIVEAUX MIS
Abstract
(EN)
The present invention is directed to a minimally invasive surgery multi-level compressor/distractor instrument that provides both linear and lordotic/kyphotic induced compression and distraction. In some embodiments, the minimally invasive surgery multi-level compressor/distractor instrument decouples from its threaded mechanism to provide freedom during assembly to the spinal construct. In some embodiments, the minimally invasive surgery multi-level compressor/distractor instrument utilize support tubes as a two for one to provide strength to the tower or implant during compression or distractor manipulation and to also engage the set screw for reduction and tightening/loosening purposes. In some embodiments, the support tubes provide strength to the tower or implant internally where as other devices are external which requires a larger incision.
(FR)
La présente invention concerne un instrument de compression/distraction multiniveaux pour chirurgie mini-invasive qui fournit à la fois une compression et une distraction induites par lordose/cyphose. Dans certains modes de réalisation, l'instrument de distraction/distraction multiniveaux de chirurgie mini-invasive se découple de son mécanisme fileté pour fournir une liberté pendant l'assemblage à la construction rachidienne. Dans certains modes de réalisation, l'instrument de compression/distraction multiniveaux de chirurgie mini-invasive utilise des tubes de support à raison de deux pour une afin de fournir une résistance à la tour ou l'implant pendant la manipulation de compression ou de distraction et afin de venir également en prise avec la vis de réglage pour une réduction et un serrage/desserrage. Dans certains modes de réalisation, les tubes de support confèrent une résistance à la tour ou à l'implant à l'intérieur où d'autres dispositifs sont externes qui nécessitent une incision plus grande.
