Abstract

L'invention concerne un élément de fixation d'os à plusieurs axes destiné à être utilisé dans une fixation spinale pour interconnecter une tige spinale longitudinale avec la vertèbre d'un patient. L'élément de fixation d'os à plusieurs axes comprend de préférence un ancrage d'os, une pince, un corps et un capuchon de verrouillage. L'élément de fixation d'os à plusieurs axes permet de préférence un assemblage in situ. C'est-à-dire que l'élément de fixation d'os à plusieurs axes est de préférence configuré de sorte qu'en utilisation, l'ancrage d'os peut être fixé sur la vertèbre du patient avant d'être reçu dans le corps. En conséquence, l'élément de fixation d'os à plusieurs axes permet au chirurgien d'implanter l'ancrage d'os sans le corps pour maximiser la visibilité et un accès autour du site d'ancrage. Une fois que l'ancrage d'os a été fixé sur la vertèbre du patient, le corps peut être emboîté sur l'ancrage d'os. L'ancrage d'os comprend également de préférence une seconde interface d'outil, de sorte qu'un instrument chirurgical peut être couplé directement à l'ancrage d'os.
