H3, h6: the cori, real intelligence robotic drill, part number rob10013, (b)(6), intended for use in treatment was returned for evaluation.A relationship between the reported event and the device was established.The reported problem was visually confirmed, the strain relief on the robotic drill is torn.A functional evaluation was performed, and the reported problem was confirmed, the strain relief on the robotic drill is torn.However, the drill did not have an issue with registration, a kpc test and case were both able to be completed without error.The drill seems to be functioning as intended.The most likely cause of this event was normal wear 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 the reported complaint.Refer to the real intelligence cori for knee arthroplasty user manual, section assembling the robotic drill for proper set up and handling.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.
