Event Description
|
It was reported that during a set up for a cori assisted tka surgery, the real intelligence robotic drill would not pass kpc/drill diagnostics testing.The "max stop speed" failed consistently.The procedure was completed, without delay, using a s+n back-up device.Since incident occurred before procedure, patient was not involved.Upon investigation, the exposure motor was found to work intermittent.

The cori drill, intended for used 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.A kpc test was try to be run unsuccessfully.The system display critical error during the kpc testing.A case was tried as well, and the system showed a timeout error followed by a drill flicker icon at the connection screen.The exposure motor was found to work intermittent.It was removed and retained for further analysis.A supplemental report will be sent with the results of investigation when completed.Internal complaint reference number: (b)(4).

Section h3, h6: the real intelligence robotic drill, part number rob10013, serial number (b)(6), intended for treatment was returned for evaluation.A relationship between the reported event and the device was established.The reported problem could not be confirmed with a visual inspection.Nothing was identified visually that contributed to the reported problem.The reported problem was confirmed with a functional evaluation.The reported problem was confirmed.A kpc test was try to be run unsuccessfully.The exposure motor was found to work intermittent.It was removed and retained for further analysis.A complaint history review for similar reported/confirmed complaints has identified prior events.A review of manufacturing records indicate the device met all specifications upon release into distribution.The failure mode and associated risk have been anticipated within the risk file.As a result of the risk assessment the quality team has been notified for further investigation.A historical review concluded that the lot/ serial number reported in this event is related to nc-22679.The most likely cause of this event is associated with an electrical communication failure.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.

H7: if remedial action initiated, check type and h9: if action reported to fda under 21 usc 360i(f), list correction/removal reporting number section h3, h6: the real intelligence robotic drill, part number rob10013, serial number (b)(6), intended for treatment was returned for evaluation.A relationship between the reported event and the device was established.The reported problem could not be confirmed with a visual inspection.Nothing was identified visually that contributed to the reported problem.The reported problem was confirmed with a functional evaluation.The reported problem was confirmed.A kpc test was try to be run unsuccessfully.The exposure motor was found to work intermittent.It was removed and retained for further analysis.A complaint history review for similar reported/confirmed complaints has identified prior events.A review of manufacturing records indicate the device met all specifications upon release into distribution.The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still adequate.We have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.A historical review concluded that the lot, serial number or part number reported in this event is related to a corrective/preventive action already implemented.The most likely cause of this event is associated with a failure of the drill exposure motor due to the thermo-mechanical stress induced within the motor at the encoder and electrical noise on the console error status inputs to the drill exposure motor encoder.Continuous improvements have been made to the cori robotic drill and manufacturing processes to reduce drill disconnection error messages.These improvements consisted of: 1.A hardware update to the cori console to reduce noise on the internal electronics.2.An update to the cori system¿s software and firmware to improve the user experience when error messages are displayed, and 3.A hardware update to the cori drill to reduce mechanical stress on drill exposure the motor.The first two improvements are fully deployed.The third improvement is being deployed for new orders and as drills are returned for routine servicing.Also, smith+nephew is voluntarily performing a recall/field notification for the cori real intelligence robotic drill.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.H6: medical device problem code, component code, type of investigation, investigation findings and investigation conclusions.
