Methods and apparatuses for providing a reference array input device for use with a computer-aided surgical navigation system. A reference array input device according to an embodiment of the present invention is configured to provide a plurality of fiducial members comprising portions capable of being sensed by at least two sensors associated with the computer-aided surgical navigation system in order to determine position and orientation of the reference array input device by the system. The reference array input device can include a plurality of indicator detectors adapted to facilitate selection of a corresponding instruction associated with the computer-aided surgical navigation system. The reference array input device can also include a mount adapted to support the reference array input device adjacent to an object, a surgical instrument, or a joint replacement prosthesis.

L'invention concerne des procédés et des dispositifs pour l'établissement de dispositif d'entrée de réseau de référence destiné à être utilisé avec un système de navigation chirurgical informatisé. Selon une variante, le dispositif décrit fournit plusieurs éléments de référence ayant des parties susceptibles d'être détectées par au moins deux capteurs associés au système de navigation chirurgical informatisé, ce qui permet de déterminer la position et l'orientation du dispositif au moyen du système. Le dispositif peut comprendre plusieurs détecteurs indicateurs facilitant la sélection d'une instruction correspondante associée au système. Le dispositif peut aussi comprendre une monture le soutenant en position adjacente à un objet, un instrument chirurgical, ou une prothèse d'articulation.
