H3, h6: the real intelligence cori, pn: rob10024, sn: (b)(6) used for treatment was not returned to the designated complaint unit for evaluation, and the cori log files and/or case files were not provided.Therefore visual and functional inspections and log/case file assessments could not be performed, and the reported problem could not be confirmed.Email correspondence between the recon representative and the robotics account representative suspect that one of the flat markers wasn¿t secure to the drill tracker, indicating that this was the possible cause of the drill not calibrating.Although the drill, tracker, and flat markers were not sent back, this possible cause could not be confirmed.Other possible contributing factors could be an issue with the drill itself, or possibly an intermittent software error.The clinical/medical evaluation concluded: ¿based on the information provided, patient impact beyond using an approved manual/modified procedure and the 0-30-minute surgical delay would not be anticipated as the surgeon was reportedly satisfied with the outcome and no patient injury was alleged.No further medical assessment is warranted at this time.¿ this situation is captured in the risk assessment released at the time of the complaint.The failure mode and associated risk have been anticipated within the risk file and that the documented risk level is still adequate.A review of manufacturing records indicate the software met all specifications upon release into distribution.A complaint history review found similar reports.A review of prior escalation actions was performed and found no actions that are applicable to the scope of the reported complaint.This issue will be continuously monitored through complaint investigation and post market surveillance.No containment or corrective actions are recommended at this time.If the case logs and/or product associated with this event is returned at a future date, this evaluation will be reopened for investigation.
