Abstract:
1. A system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery, the system comprising: a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier; a sensor alignment mechanism configured to secure the optical sensor through the sterile drape in alignment with the optically transparent window without breaching the sterile barrier and further configured to facilitate adjustment of the orientation of the optical sensor to align the optical sensor to view a surgical site when the system as assembled with the optical sensor is mounted for use during the surgery, wherein the sensor alignment mechanism comprises: a shroud, which when engaged with the optical sensor when draped, secures the optical sensor through the sterile drape in alignment with the optically transparent window; and a clamp, which in a closed position is configured to rigidly hold the assembled shroud, sterile drape and optical sensor while preserving the optical sensor alignment in the optically transparent window.
