A system (1010, 1110) for identifying a landmark is disclosed. The system includes a field generator (1016, 1116) for generating a magnetic field, an orthopaedic implant (1030, 1130) located within the magnetic field, the implant having at least one landmark (1028,1128), a removable probe (1029, 1129) with a first magnetic sensor (1026,1126), a landmark identifier (1016, 1116) with a second magnetic sensor (1020, 1120) and a processor (1012, 1112) for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.
L'invention concerne un système (1010, 1110) permettant d'identifier un point de repère. Le système comprend un générateur de champ (1016, 1116) permettant de générer un champ magnétique, un implant orthopédique (1030, 1130) situé dans le champ magnétique, l'implant comprenant au moins un point de repère (1028, 1128), une sonde amovible (1029, 1129) dotée d'un premier capteur magnétique (1026, 1126), un identifiant de point de repère (1016, 1116) doté d'un second capteur magnétique (1020, 1120) et un processeur (1012, 1112) permettant de comparer les données de capteur des premier et second capteurs et utilisant la distance déterminée pour calculer la position de l'identifiant de point de repère par rapport au moins à un point de repère. Le système permet de cibler sans visibilité un ou plusieurs points de repère.
