During inspection and testing, in addition to the damaged bending section and bending section cover, a leak was observed on the insertion tube due to a cut in the adhesive rubber, confirming the customer's reported issue.A review of the device history record found no deviations that could have caused or contributed to the reported issue.The device met all specifications at the time of shipment.Based on the results of the legal manufacturer's investigation, the damage observed at the bending section and bending section cover was likely the result of excessive force being applied to the bending section.However, a definitive root cause could not be determined.The event can be detected by following the instructions for use which state: ¿precautions: perform a leakage test on the endoscope after each precleaning procedure.Do not use the endoscope if a leak is detected.Use of an endoscope with a leak may cause a sudden loss of the endoscopic image, damage to the bending mechanism, or other malfunctions.Use of a leaking endoscope may also pose an infection control risk." "inspection of the endoscope: inspect the external surface of the entire insertion section, including the bending section and the distal end for dents, bulges, swelling, scratches, peeling of coating, holes, sagging, transformation, bends, adhesion of foreign bodies, missing parts, protruding objects, or other irregularities." the event can be prevented by following the instructions for use which state: "-do not operate the angulation control lever with excessive force in a narrow space to the opposite direction from the bending direction while the distal end of the endoscope is not moved.The bending section may be damaged.Check the tip position of the endoscope and the shape of the bending section using fluoroscopy, etc.Do not insert the insertion tube with excessive force and twist.Do not insert the insertion tube with excessive force into the ureter or calix.The bending section may be damaged.¿ olympus will continue to monitor field performance for this device.Investigation activities have been opened to manage the actions related to this issue and any required mdr reporting.
