Section h10: the ri robotic drill attachment rob10015, sn (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 was confirmed, the drill attachment and the tracker could not be removed manually or following a kpc test.The reported problem of a "system timeout error" could not be confirmed.The drill was opened for further investigation.The exposure motor was tested and passed.The motors were removed, and it was noticed that the drill attachment¿s retaining nut was loose and therefore does not meet the specifications of 20 ft-lbs.The drill attachment was inspected further, and all bearings and spacers were intact and in the correct order.The drill attachment¿s retaining nut was fastened and a kpc test was performed which passed without any failures.The loading and unloading of the tracker and attachment can be performed without any problems occurring.An engineering review was completed.The exposure motor was tested and found to be responsive.The most likely cause of this event is associated with a loose drill attachment retaining nut.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.The review determined that prior escalation actions are applicable to the part number or serial number and scope of this complaint, and no further escalation action is required.The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still adequate.As part of corrective actions, continuous improvements have been made to the assembly process.The assembly work instruction has been updated to include the application of a thread-lock compound to the drill attachment retaining nut during assembly.The failure mode will continue to be monitored through complaint investigation and trended through post market surveillance activities.Internal complaint reference number: (b)(4).
