The device was returned to olympus for evaluation.The evaluation confirmed that the bending section skeleton was protruding out from the bending section cover, exposing metal and causing the bending section cover to leak.The bending section cover was removed and found the bending section skeleton was broken below the insertion tube side and distal end side where the leak was observed.The broken bending section skeleton caused the bending section cover to be stretched and cut (hole).It was noted that the broken skeleton caused an abnormal shape to the bending section, when the up/down lever was manipulated.This type of bending section damage is attributed to excessive force.The instruction manual warns user "do not strike, hit, or drop the endoscope¿s distal end, insertion tube, bending section, control section, universal cord, video connector, or light guide connector.Also, do not bend, pull, or twist the endoscope¿s distal end, insertion tube, bending section, control section, universal cord, video connector, or light guide connector with excessive force.The endoscope may be damaged and could cause patient injury, burns, bleeding, and/or perforations.It could also cause parts of the endoscope to fall off inside the patient.".
