H6: the real intelligence cori, pn: rob10024, sn: (b)(6) used for treatment was not returned to the designated complaint unit for evaluation, therefore visual and functional inspections could not be performed.Although the product was not returned the software files were downloaded from the device and provided for investigation.Screenshots of the case were provided and confirmed the two warning messages upon entering the tibia bone removal stage: ¿bone model generation error.¿ as part of corrective actions, the tibia bone model generation error has been corrected and released in cori-v1.4.3 software.The internal errors occurring after the drill disconnect error were also confirmed via log file review.The drill was not returned for investigation.However, having reviewed the log files, the most likely cause of these reported errors are related to the drill temperature sensor.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.Escalation actions applicable to the scope of the reported complaint have been identified, and it was determined that no further action is required at this time.This issue will be continuously monitored through complaint investigation and post market surveillance.Based on the investigation, no containment or corrective actions are recommended at this time.
