Methods and apparatuses for providing a patient-mounted navigational sensor (100) for use in computer-aided surgery are disclosed. A navigational sensor according to embodiments of the invention includes at least two optical tracking cameras for sensing surgical references and a mount adapted to be attached to the bone of a patient. Because the sensor is mounted to the bone rather than to external apparatus, and is thus closer to the surgical references that it is tracking, it is less likely that line of sight issues due to an acute angle between the plane of the surgical reference and the sensor or due to medical personnel obstructing the path of the reference's signal. Because the navigational sensor is much closer to the surgical references being tracked than in a typical computer-aid surgery scenario, the required camera separation is greatly reduced. Other advantages also accrue from such sensor positioning, as related more fully in this document.

Des procédés et des appareils fournissant un capteur (100) de navigation monté sur un patient que l'on utilise dans la chirurgie assistée par ordinateur. Le capteur comprend au moins deux caméras de suivi permettant de capter les références chirurgicales et une monture apte à être fixée sur l'os d'un patient. Etant donné que le capteur est monté sur l'os plutôt que sur l'appareil externe, et qu'il est par conséquent plus proche des références chirurgicales qu'il suit, il y a moins de risque d'avoir des lignes de visée à problème en raison d'un angle aigu entre le plan de référence chirurgicale et le capteur ou en raison du personnel médical empêchant la trajectoire du signal de référence. Etant donné que le capteur de navigation est plus proche des références chirurgicales en cours de suivi qu'un scénario chirurgical typique assisté par ordinateur, la séparation de la caméra nécessaire est fortement réduite. D'autres avantages proviennent du positionnement du capteur.
