Abstract

La présente invention concerne les cages interosseuses insérées entre deux portions d’os O1, O2. La cage selon l’invention comporte un corps 10 ; au moins une lame 20 définissant un plan de coupe 21 et présentant un bord en fil de coupe 25 ; des moyens 30 pour monter la lame en rotation par rapport au corps 10, cette rotation étant apte à s’effectuer autour d’un axe 31 sensiblement perpendiculaire au plan de coupe 21 de façon qu’au moins une partie du bord en fil de coupe 25 soit apte à pénétrer dans une portion d’os O1, O2 ; au moins une contre-lame 40 définie sensiblement selon une portion de surface sensiblement cylindrique de révolution 41 avec un bord d’attaque de coupe 44 ; et des moyens pour solidariser cette contre-lame avec une face 22 de la lame 20 de façon que l’axe de la portion de surface cylindrique de révolution soit sensiblement confondu avec l’axe de rotation 31 de la lame. Application, notamment, à la réalisation de cages intervertébrales.The present invention relates to the interosseous cages inserted between two portions of bone O1, O2. The cage according to the invention comprises a body 10; at least one blade 20 defining a cutting plane 21 and having a cutting line edge 25; means 30 for mounting the blade in rotation relative to the body 10, this rotation being able to take place around an axis 31 substantially perpendicular to the cutting plane 21 so that at least part of the cutting edge 25 is capable of penetrating a portion of bone O1, O2; at least one counter-blade 40 defined substantially according to a substantially cylindrical surface portion of revolution 41 with a cutting leading edge 44; and means for securing this counter-blade to a face 22 of the blade 20 so that the axis of the cylindrical surface portion of revolution is substantially coincident with the axis of rotation 31 of the blade. Application, in particular, to the production of intervertebral cages.
