Methods and apparatuses for providing a reference array input device
First Claim
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.

Abstract
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.
