EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
• When the biopsy valve’s cap is detached from the main body,
it may cause patient debris or fluids to leak or spray from the
endoscope, posing an infection-control risk. When the biopsy
valve’s cap has to be detached, place a piece of sterile gauze
over it to prevent leakage.
• Do not let the endo-therapy accessory “hang down” from the
biopsy valve. Doing so can create a space between the
accessory and the valve’s slit or hole and/or damage the
valve, which can reduce the efficacy of the endoscope’s
suction system, and may leak or spray patient debris or
fluids, posing an infection-control risk.
• When inserting an endo-therapy accessory, hold it close to
the biopsy valve and insert it slowly and straight into the
biopsy valve. Otherwise, the endo-therapy accessory and/or
biopsy valve could be damaged. This can reduce the efficacy
of the endoscope’s suction system, and may leak or spray
patient debris or fluids, posing an infection-control risk.
1. Select endo-therapy accessories compatible with the instrument from the
“System chart” in the Appendix. Refer to the accessories’ instruction
manuals for operating instructions.
2. Hold the UP/DOWN and RIGHT/LEFT angulation knobs stationary (the
GIF-N180 has only the UP/DOWN angulation control knob).
3. Confirm that the tip of the endo-therapy accessory is closed or retracted into
its sheath and insert the endo-therapy accessory slowly and straight into the
slit of the biopsy valve.
• Do not open the tip of the endo-therapy accessory or extend
the tip of the endo-therapy accessory from its sheath while
the accessory is in the instrument channel. The instrument
channel and/or the endo-therapy accessory may become
damaged.
• Hold the endo-therapy accessory close to the biopsy valve
and insert it straight into the biopsy valve using slow, short
strokes. Otherwise, the endo-therapy accessory could bend
or break.
4. Hold the endo-therapy accessory approximately 4 cm from the biopsy valve
and advance it slowly and straight into the biopsy valve using short strokes
while observing the endoscopic image.
