Chapter 4 Operation
Angulation of the distal end
Air/water feeding and suction
46
Avoid forcible or excessive angulation as this imposes stress
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.
• When passing an EndoTherapy accessory through the
instrument channel while the angulation is locked, the angle
of the distal end may change. When it is necessary to keep
the angulation stationary, hold the angulation control knobs in
place with your hand.
• When operating the UP/DOWN or RIGHT/LEFT angulation
lock, hold the angulation control knob stationary with your
finger. If this is not done, the angulation will change.
• If the sterile water level in the water container is too low, then
air, not water, will be supplied. In this case, turn the airflow
regulator on the light source OFF and add sterile water to the
water container until it reaches the specified water level.
• If air/water feeding does not stop, turn the airflow regulator
on the light source OFF and replace the air/water valve with a
new one.
• Before using a syringe to inject liquid through the biopsy
valve, detach the valve's cap from the main body. Then insert
the syringe straight into the valve and inject the liquid. If the
cap is not detached and/or the syringe is not inserted
straight, the biopsy valve could be damaged. This could
reduce the efficacy of the endoscope's suction system, and
may leak or spray patient debris or fluids, posing an infection
control risk.
