It was reported that, during femur burring during a navio tka procedure, they got a handpiece exposure control motor error forcing them to recalibrate the handpiece.This happened three times (it would calibrate and home without issues but would immediately boot them back to the calibration screen every time they got to the burring screen).They decided to get a new handpiece and were able to finish the case without further problems.There was a delay of fewer than 30 minutes.No other complications were reported.

H3, h6: the navio handpiece, part number pfsr110137, serial (b)(6) and intended to be used for treatment, was returned for evaluation.A relationship between the reported event and the device was established.The reported problem could not be visually confirmed.A functional evaluation was performed.The reported problem was confirmed.The "cannot communicate with the handpiece" error appeared before the test could start 3 times.A review of manufacturing records indicate the device met all specifications upon release into distribution.A complaint history review for similar reported/confirmed complaints has identified prior events.The most probable cause of the reported problem is internal electrical failure in cable.Although no further containment or corrective action is recommended or required at this time, all complaints are monitored and trended through post market surveillance activities.
