It was reported that, during set-up for a cori assisted tka, a real intelligence robotic drill had a communication error and displayed "put in contact with customer support robotics".The procedure was resumed, after a non-significant delay, by changing to a manual procedure.Since the issue was noticed before procedure, patient was not yet involved.

Section h10: the real intelligence robotic cori drill (b)(4), (b)(6), used during treatment, was returned for evaluation.Nothing was visually identified that leads to the reported scenario.A functional evaluation was performed, and the reported scenario cannot be confirmed.A key performance characteristics (kpc) test and a test case were performed and were completed without showing the ¿communication error¿ mentioned in the reported complaint, or any additional errors.The drill was opened for further investigation.The exposure motor was tested and passed.The thermistor was tested and passed.The drill was disassembled but no defects were found.The drill was reassembled, and a test case was performed again.Again, no failures occurred.The drill is functioning as intended.An engineering review was completed.The exposure motor was tested and found to be responsive.Although the reported problem could not be confirmed through a visual or functional evaluation, factors that may have contributed to the reported symptom may have been associated an intermittent connection between the drill and the console.A review of manufacturing and service records indicate the device met all specifications upon release into distribution.A complaint history review for similar reported/confirmed complaints found similar events.A historical escalation event review was completed.A review of prior escalation actions found no actions applicable to the scope of the reported complaint.The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still adequate.Although no further containment or corrective action is recommended or required at this time, the failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.Internal complaint reference number: (b)(4).
