8. Inspect the objective lens and light guide lens at the distal end of the
endoscope’s insertion section for scratches, cracks, stains, or other
irregularities.
9. Inspect the air/water nozzle at the distal end of the endoscope’s insertion
section for abnormal swelling, bulges, dents, or other irregularities.
Inspection of the flexibility adjustment mechanism
(for endoscopes with flexibility adjustment only)
1.
Confirm that the marks (“”, “1”, “2”, “3”) on the flexibility adjustment ring
and the “ ” mark at the bottom of the grip section are clearly visible (see
Figure 3.5).
Figure 3.5
Do not use the endoscope if the markings are not clearly
visible. If the operator is uncertain of the flexibility of the
insertion section, insertion and manipulation of the
endoscope may cause patient pain, injury, bleeding, and/or
perforation.
2. Confirm that the flexibility adjustment ring can be turned smoothly when the
insertion section is straight.
If the insertion section is coiled too tightly, the flexibility
adjustment ring may not operate smoothly. This does not
indicate a malfunction.
