Philips investigated the reported event.According to the information collected, the system was in clinical use, however the procedure (non-emergency treatment) had been concluded when the issue occurred.There was no impact to the patient/user.Philips investigated the reported issue and confirmed that the motor assembly was retained by a cable (d-type connector) and the z-rotation cover by its retaining safety chain.However, the z-rotation motor assembly and z-rotation cover got detached from the l-arm.An initial analysis of the z-rotation motor assembly was performed, and it was found to be caused due to the gearbox mounting/output flange separating (coming loose) from the gearbox housing/assembly, resulting in a loss of position fixation of the z-rotation motor assembly.The z-rotation assembly was replaced, and the system was returned in good working order.
