Event Description
|
It was reported that a patient underwent a functional endoscopic sinus surgery (fess) revision surgery with a trudi¿ navigation system and a location inaccuracy occurred.An issue was reported the trudi curette being "off" versus the suction device when compared head to head in the same anatomy.In this case, the curette was only off by 2mm versus the suction so was technically within our labeled specs - but the surgeon did not find the inaccuracy acceptable.There was no injury to patient.No concerns at all related to the patient health or safety.Troubleshooting was comparing the curette (which was appearing "off" embedded in the posterior table bone) directly in that same anatomy to the suction device.The surgeon who registered had been trained and had registered multiple times.Since the complaint is about the difference between curette and suction, registration is not the issue.The accuracy was confirmed using the registration probe after registration process was completed and with known landmarks in endoscopic visualization inside the nasal cavity.Inaccuracy was confirmed multiple ways during registration and on all areas of the face with the registration probe (rp) and then on the face with the instrument and then inside the nose on known landmarks throughout the rest of the case until getting to this anatomy.Suction was accurate, curette was accurate in most anatomy except for this one area.There were more than 100 ct sliced and the registration was accurate.Field of view was described as great.Reistration was not redone after identifying the issue.There is always a potential for metal interference in the operating room (or).This event was originally considered non-reportable, however, a product investigation identified a reportable product malfunction on 1-sep-2023.
