Event Description
|
It was reported that, after a successful cori assisted case with no errors, the robotic drill attachment could not be removed.A kpc test was attempted to unlock the real intelligence robotic drill manually but it would not unlock.The drill passed a kpc test.A new case was entered and a disconnect error displayed.They returned to kpc test and an internal error displayed.Since event occurred after the case, there was no patient involved.

Manufacturer Narrative

H3, h6: the ri robotic drill p/n rob10013, sn (b)(6), intended for use in treatment was returned for evaluation.A relationship between the reported event and the device was established.Nothing was identified visually that contributed to the reported problem.A functional evaluation was performed.The reported problem was confirmed.The drill attachment could not be removed manually.The drill attachment could not be removed through the kpc unlock process.The drill motors were removed and the carriage was free to move to unlock position.The drill attachment could be removed.The drill was reassembled and a known good drill attachment was attached and detached.Drill attachment retaining nut has unthreaded from drill attachment placing additional force on the drill nose piece, prohibiting the carriage from properly extending, prohibiting the drill attachment rotation and removal.The most likely cause of this event is the drill attachment retaining nut has unthreaded from drill attachment placing additional force on the drill nose piece, prohibiting the carriage from properly extending, prohibiting the drill attachment rotation and removal.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, the failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.
