Title
(EN) FENESTRATED BONE ANCHOR
(FR) ANCRAGE OSSEUX FENÊTRÉ
Abstract
(EN)
Disclosed is a fenestrated bone anchor (210) suitable for being anchored in live bone tissue of a human or animal patient. The bone anchor comprises a shaft with a proximal end and a distal end and a circumferential surface extending from the proximal end to the distal end. The shaft further comprises a longitudinal cavity extending from the proximal end towards the distal end and a plurality of lateral channels extending through a wall of the shaft from the axial cavity to the circumferential surface. The lateral channel has a pear-shaped cross section and/or the thickness of the wall increases gradually in selected ones of directions towards the lateral channels. The fenestrated bone anchor is e.g. a component of a surgical system comprising an interbody fusion device of the stand-alone type.

Est divulgué un ancrage osseux fenêtré (210) approprié pour être ancré dans un tissu osseux vivant d'un patient humain ou animal. L’ancrage osseux comprend une tige dotée d’une extrémité proximale, d’une extrémité distale, et d’une surface circonférentielle s'étendant de l'extrémité proximale à l'extrémité distale. La tige comprend en outre une cavité longitudinale s'étendant de l'extrémité proximale vers l'extrémité distale et une pluralité de canaux latéraux s'étendant dans une paroi de la tige de la cavité axiale à la surface circonférentielle. Le canal latéral présente une section transversale en forme de poire et/ou l'épaisseur de la paroi augmente progressivement dans des directions sélectionnées parmi celles menant aux canaux latéraux. L'ancrage osseux fenêtré est, par exemple, un élément d'un système chirurgical comprenant un dispositif de fusion intersomatique du type autonome.
