Event Description
|
It was reported that during a cori tka procedure, several "robotic drill disconnect" errors were displayed, and were not resolved by troubleshooting.Although they recommended either rebooting the system or opening another drill (unknown which is causing the issue), the surgeon proceeded with manual instrumentation.There was a delay of greater than 30 minutes.After the procedure, they performed a drill test and received a message "robotic drill critical error".After disconnecting and reconnecting the drill twice, they were able to bypass this error, but the drill continued to operate in an unusual manner, with excessive clicking noises and "jumping" at the nose of the drill.No other complications were reported.

Manufacturer Narrative

H3, h6: the real intelligence robotic drill, part number rob00013, s/n (b)(6), used for 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 review was completed.The reported problem was not confirmed.The drill was able to pass kpc testing and functioned as designed during a mock saw bones case.A log file review was performed.The log file review confirmed the reported multiple drill disconnect errors.The most likely cause of this event is related to an internal loose connection in the motor.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 scope of this complaint and the capa owner has been notified to consider further escalation action.The real intelligence cori for knee arthroplasty user manual provides guidelines for recovering to a fully manual procedure in the "recovery procedure guidelines".The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still adequate.Per complaint details, the "drill disconnect¿ error occurred during a cori tka procedure and troubleshooting resulted in further error messages.Reportedly, the surgeon decided to proceed with manual instrumentation which resulted in a ¿greater than 30-minute¿ surgical delay.However, no patient injury was reported, and it was communicated that ¿the patient¿s health is good¿.Per correspondence, operative reports are not available; however, no patient harm/injury resulted in the case and no other interventions were reported.The procedure was reportedly completed manually with a 30-plus-minute surgical extension without report of patient injury/harm; therefore, no further patient impact would be anticipated.No further medical assessment is warranted at this time.Further investigation into the reported failure is being conducted to determine if additional actions are required.The failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.
