REAL-TIME ADJUSTMENT OF HAPTIC FEEDBACK IN SURGICAL ROBOTS

Abstract: haptic feedback from a robotic surgical tool can be adjusted based on intra-operative assessment of the accuracy of a pre-operative surgical navigational plans. navigational reference points are identified in at least one pre-operative image. at least one haptic response is identified for interactions between at least one robotic surgical tool and at least one navigational reference point. at least one intra-operative image is compared to the pre-operative image to determine the relative position of at least two corresponding navigational reference points in the images. the reference points' relative position determines a confidence level in the accuracy of the pre-operative navigational reference point. the haptic response is adjusted in timing, location, type, or amplitude based upon the confidence level. tolerances and surgical navigation plan may also be updated and altered based on the confidence level.
