ULTRASOUND GASTROVIDEOSCOPE GF-UCT180
13.2 Withdrawal of the endoscope with an irregularity
If an irregularity occurs while the endoscope is in use, take proper measures as
described in either “Withdrawal when the WLI and NBI endoscopic images
appear on the monitor”, “Withdrawal when EITHER the WLI or the NBI
endoscopic image does not appear on the monitor”, “Withdrawal when all
endoscopic images do not appear on the monitor or a frozen image cannot be
restored” below. After withdrawal, return the endoscope for repair as described
in Section 13.3, “Returning the endoscope for repair” on page 220.
If the endoscope or EndoTherapy accessory cannot be
withdrawn from the patient smoothly, do not attempt to
forcibly withdraw it. Should any irregularity be observed,
immediately contact Olympus. Forcibly withdrawing the
endoscope or EndoTherapy accessory may cause patient
injury, bleeding, and/or perforation.
Withdrawal when the WLI and NBI endoscopic images appear
on the monitor
1.
Turn all equipment OFF except the video system center, light source,
monitor, and suction pump.
2. When the NBI endoscopic image is displayed, switch to the WLI endoscopic
image by operating the video system center and light source.
3. When using an EndoTherapy accessory, close the tip of the EndoTherapy
accessory and/or retract it into its sheath. Then withdraw the EndoTherapy
accessory slowly while lowering the forceps elevator gradually.
4. Aspirate accumulated air, blood, mucus, or other debris by depressing the
suction valve to the first stage.
5. Turn the UP/DOWN and RIGHT/LEFT angulation locks in the “F ”
direction to release them.
6. Carefully withdraw the endoscope while observing the endoscopic image.
Remove the mouthpiece from the patient’s mouth.
