Inspection of the bending mechanism
Perform the following inspections while the bending section is straight.
Figure 3.9
• If the movement of the angulation control lever is loose and/or not smooth, or the
bending section does not angulate smoothly, the bending mechanism may have an
irregularity. In this case, do not use the endoscope because it may be impossible to
straighten the bending section during an examination, and patient injury, bleeding,
and/or perforation may result.
• When rotating the insertion section, the bending section bends to a different
direction against the control section. Before operating the angulation control lever,
make sure to check the position of the UP indication of the insertion tube rotation
ring and endoscopic image. Otherwise, the bending section may bend to a different
direction as intended and patient injury, bleeding, and/or perforation could result.
