Event or Problem Description
The healthcare professional reported that during a hybrid revision functional endoscopic sinus surgery (fess) procedure, it was reported that the 0° trudi nav suction device (tdns000z / 2112030) was inaccurate on the trudi navigation system.They exchanged the suction device for another 0° trudi nav suction device from the same lot number, (tdns000z / 2112030) and the issue reportedly persisted.It was reported that the second 0° trudi nav suction device was replaced with a 70° trudi nav suction device (tdns070z / 2112087) and the same issue persisted.The 70° trudi nav suction device was replaced with a 90° trudi nav suction device (tdns090z / 2109179) and the same issue persisted.The patient tracker was then exchanged; the replacement patient tracker was re-registered and tried with two (2) different navigation cables, but the issue persisted.The procedure was continued without any further troubleshooting.The physician is aware of the inaccuracies.There was no report of any patient adverse event or patient complication as a result of the reported inaccuracies.On (b)(6) 2022, additional information was received.The information indicated that the accuracy issue was noticed immediately when the suction device was on the bridge of the nose; when the accuracy issue was observed, the icon on the trudi system was green.There was no error message on the trudi nav monitor for the device; the information indicated that the ¿accuracy was just off.¿ the suction devices were plugged in after registration.The information also indicated that this is an ongoing issue, the patient tracker was not moved nor was the patient tracker cable under tension in relation to this event.Computed tomography (ct) image was used as the primary image.The number of slices contained in the ct scan is unknown.The inaccuracy issue was determined with known landmarks like the bridge of the nose and the base of the skull.The inaccuracy was not within 2 mm.There was no ferromagnetic material placed within the trudi zone.The crosshairs did not turn yellow.The emitter pad and the patient did not move.Related to the reprocessing of the devices, it was the first use for the one (1) of the four (4) suctions, for the remaining suctions, it was the fourth use for one, fifth use for one and sixth use for one.No identifying details on which suctions is which was provided.Sterilization method used for reprocessing was via the sterrad sterilizer.Based on the additional information, the reported issues have been deemed reportable as a "malfunction".
