Title
(EN) SET SCREW AND SET SCREW DRIVING TOOL FOR IMPROVED ROD ALIGNMENT
(FR) VIS DE PRESSION ET OUTIL DE VISSAGE DE VIS DE PRESSION POUR UN ALIGNEMENT DE TIGE AMÉLIORÉ
Abstract
(EN)
A set screw for threadable engagement with a head of a pedicle screw for holding a spinal rod, the set screw having a spinal rod facing side and a set screw driver facing side, the set screw including an opening at the set screw driver facing side for engaging with the set screw driver, and a convex surface at the rod facing side, an apex of the convex surface substantially corresponding with a rotational central axis of the set screw.
(FR)
L'invention concerne une vis de pression permettant une mise en prise par filetage avec une tête d'une vis pédiculaire servant à maintenir une tige vertébrale, la vis de pression comportant un côté faisant face à la tige vertébrale et un côté faisant face à un dispositif de vissage de vis de pression, la vis de pression comprenant une ouverture au niveau du côté faisant face au dispositif de vissage de vis de pression pour venir en prise avec le dispositif de vissage de vis de pression, et une surface convexe au niveau du côté faisant face à la tige, un sommet de la surface convexe correspondant sensiblement à un axe central de rotation de la vis de pression.
