Additional Manufacturer Narrative
Based on the information received from the investigation, it was deemed as a user error as there was misuse of mizuho osi table along with mazor x steath (non-mizuho osi product) contrary to published instructions by mazor/medtronic that mentioned "the surgical table movement feature must be disabled during surgery with the mazor x stealth edition surgical system".Table was actively tilted with the mazor x arm attached, which caused failure of the tilt actuator due to the excess movement load imparted by the mazor x stealth robot system/arm.It is also believed that there was a misuse by lack of regular preventative maintenance of a table that is 14+ years old along with of documented yearly preventative maintenance.The adjustment of the head and foot end brakes was also found to be non-compliant with the specifications mentioned in the owner's manual.
