The urf-p6r flexible scope, sn: (b)(4) was received for evaluation due to protruded broken skeleton issue.Visual inspection on the received condition was performed and determined that the bending section skeleton tab is protruding (sticking out) from the bending section cover near the insertion tube area.Due to the protruding skeleton tab, the scope failed the leak testing.The bending section cover was removed and the bending section skeleton was found broken and separated, however, no signs of sharp edges found.Based on the device evaluation, the reported issue was confirmed.The leak on the bending section cover due to protruding skeleton tab and excessive broken fibers were confirmed and the likely root cause of the damaged was due to excessive force was applied.As a precautionary measure, the instruction manual states the following; ¿do not twist or bend the bending section with your hands¿.Additionally, the instructions for safe use manual indicate that, damage to the bending section would happen if excessive force was applied while angulating in the opposite direction if there was no movement from the bending section; this would occur more so in a narrow environment.
