The device was returned to the service center for evaluation.
A visual inspection was performed on the received scope and found the scope¿s bending section skeleton tab protruding (sticking out) from the bending section cover near the insertion tube area.
The bending section cover was removed and the bending section skeleton was found to be fully broken and separated with no signs of any sharp edges.
The skeleton tab that was protruding from the bending section cover is bent, which is the most probable cause of the skeleton breakage.
Based on the investigation, the cause of the broken bending section skeleton and bent skeleton tab is due to excessive force and/or stress attributed to mishandling the instruction manual states ¿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.

The service was informed that during preparation for use, for an unspecified diagnostic procedure, it was observed that the top of the scope¿s bending section was broken.
There was no patient involvement and therefore, no patient injury occurred.
