A low-profile rod connector is disclosed that includes two substantially conical surfaces that allows two rods to be secured together. The device is easily manipulated and occupies very little space. The connector allows for the rods to be oriented at a number of different positions prior to securing the rods in a final orientation. Medical implants utilizing the present invention include surgical implants for spine stabilization. One particular application comprises securing the shaft of a pedicle screw to a spinal rod. In such application, since the connector is relatively small, displacement and disruption to nearby tissue is minimized. The connector also has application to external fixation systems which are conducted exterior of the skin surface, as well as other mechanical devices.
L'invention concerne un connecteur de tige à profil bas comprenant deux surfaces sensiblement coniques permettant de fixer ensemble deux tiges. Le dispositif est facilement manipulé et occupe peu de place. Le connecteur permet aux tiges d'être orientées selon différentes positions avant de les fixer dans leur orientation finale. Des implants médicaux utilisant cette invention comprennent des implants chirurgicaux pour la stabilisation de la colonne vertébrale. Une application particulière consiste à fixer l'axe d'une vis pédiculaire sur une tige de colonne vertébrale. Dans une telle application, le déplacement et la rupture des tissus proches sont minimisés en raison de la petitesse relative du connecteur. Le connecteur peut aussi s'appliquer dans des systèmes de fixation externe installés à l'extérieur de la surface corporelle ainsi qu'à d'autres dispositifs mécaniques.
