H3, h6: the real intelligence robotic drill attachment, part number rob10015, serial number (b)(6), intended for use in treatment, was returned for evaluation.The reported problem could not be confirmed with a visual inspection.The reported problem was not confirmed with a functional evaluation.The drill attachment was able to be attached to a test lab drill and all diagnostics passed multiple times and multiple test case setups were completed.A relationship between the reported event and the device could not be established.Although the reported problem was not confirmed through a visual or functional evaluation, factors contributing to the reported symptom may have been associated with a drill attachment retaining nut coming loose due to vibration during use.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 failure mode and associated risk have been anticipated within the risk file.The risk level is still adequate.Based on the investigation, the need for a corrective action is not recommended or required at this time.Should any additional information be received the complaint will be reopened.The failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.
