For GIF models
1.
If necessary, apply a medical-grade, water-soluble lubricant to the insertion
tube.
2.
Place the mouthpiece between the patient's teeth or gums, with the outer
flange on the outside of the patient's mouth. I n case of transnasal insertion
(for GIF-N180 only), the mouthpiece is not used.
3.
Insert the distal end of the endoscope through the opening of the
mouthpiece, then from the mouth to the pharynx, while viewing the
endoscopic image. Do not insert the insertion tube into the mouth beyond
the insertion tube limit mark.
For CF/PCF models
To determine the correct splinting tube to use with the
endoscope, select one of the combinations shown in the
"Accessories (for CF/PCF models only)" table in the
"Appendix" on page 91.
1.
If necessary, apply a medical-grade, water-soluble lubricant to the insertion
tube.
2.
Insert the insertion tube of the endoscope into the splinting tube if required,
and apply lubricant to the splinting tube.
3.
Always view the endoscopic image when passing the distal end of the
endoscope from the anus to the rectum. Do not insert the insertion tube into
the anus beyond the insertion tube limit mark.
Avoid forcible or excessive angulation, as this imposes load
on the wire controlling the bending section. This may cause
stretching or tearing of the wire, which could impair the
movement of the bending section.
1.
Operate the angulation control knobs as necessary to guide the distal end
for insertion and observation.
2.
The endoscope's angulation locks are used to hold the angulated distal end
in position.
