Abstract

Abstract The invention is a device (300; 350; 400; 500) for use with a surgical navigation system having a sensor array (110; 112) which is in communication with the device (300; 350; 400; 500) to identify its position. The device (300; 350; 400; 500) is for guiding an instrument for engaging a body part thereby locating the instrument at a known position relative to the body part. It has a connector (340; 370; 408; 514) for engaging a cable connected to the surgical navigation system, the cable for providing signals for activating the device (300; 350; 400; 500). The device (300; 350; 400; 500) comprises: a housing (308, 310) having a cavity (312; 514) therein; a structure (304; 354; 404; 508) on the housing (308, 310) for guiding the instrument in order to maintain the instrument in a relationship relative to the housing (308, 310); a plurality of light emitting diodes (316; 510) on the housing (308, 310), said diodes (316; 510), when activated, emitting light for communicating with the sensor array (110; 112) of the surgical navigation system; a connector (340; 370; 408; 514) attached to the housing (308, 310) and adapted to engage the cable connected to the surgical navigation system, said connector (340; 370; 408; 514) for receiving the signals for activating the diodes (316; 510); and wires (314; 410; 516) located in the cavity (312; 514) of the housing (308, 310) and electrically interconnecting the connector (340; 370; 408; 514) and the light emitting diodes (316; 510) and for transmitting the signals received by the connector (340; 370; 408; 514) to the diodes (316; 510) to activate the diodes (316; 510).
