The device was returned to olympus for evaluation.The reported complaint was confirmed.A visual inspection of the device noted two critical abnormalities on the scope.A severe kink was noted on the bending section measuring at 5.2 cm from the distal end.Another severe kink with a gap was noted on the insertion tube measuring 16 cm from the distal end of the protector unit.A microscopic investigation of the insertion tube noted a gap on the insertion tube sheath measured at 3 mm, exposing the skeleton and the internal elements.Foreign materials were noted on the skeleton.The reported phenomenon is most likely attributed to excessive force due to physical damage.The instruction manual states: ¿prior to sterilizing the fiberscope, the venting cap must be attached.Oes fiberscopes are completely sealed to make them watertight.Failure to attach the venting cap will prevent the air sealed inside the fiberscope from escaping as a vacuum is created within the sterilization chamber.This will cause the rubber covering the bending section to rupture.After the ethylene oxide (eto) procedure is completed, the venting cap must be removed in order to reseal the fiberscope and insure watertightness.¿.
