H3, h6: the real intelligence robotic drill, rob10013, sn (b)(6), used for treatment was returned for evaluation.A relationship between the reported event and the device could not be established.Nothing was identified visually that contributed to the reported problem.A functional evaluation was performed.The reported issue was not confirmed.The drill was disassembled and it was found that the drill attachment bearing shaft lock nut was out of torque specification.A kpc was run and passed.The drill functions as intended without any issues.A log file review was performed.The reported problems were not confirmed.The log files do not confirm the physical events of "overheating of device" , "physical resistance/sticking" or "noise, audible".Although the reported problem was not confirmed, a factor that may have contributed to the reported symptoms may have been associated with the drill attachment bearing shaft lock nut out of torque specification causing noise, overheating and for the attachment to get stuck on the drill.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 this case.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, all complaints are monitored through complaint investigation and post market surveillance activities.
