Abstract:
1. A system comprising a reference array input device and a computer-aided surgical navigation system, wherein the reference array input device can be sensed by at least two sensors associated with the computer-aided surgical navigation system, and wherein a relative position and orientation associated with the reference array input device may be determined by the computer-aided surgical navigation system, the reference array input device comprising: (a) a plurality of fiducial markers positioned on the reference array input device and adapted to be sensed by the computer-aided surgical navigation system, wherein a position and orientation associated with the reference array input device can be determined when at least some of the fiducial markers are sensed by the computer-aided surgical navigation system; (b) at least one indication detector positioned on the reference array input device, wherein a positioning of a first object at said at least one indication detector indicates at least one instruction for execution by the computer-aided surgical navigation system; and (c) a mount adapted to support the reference array input device adjacent to a second object.
