Flexibility adjustment
(for endoscopes with flexibility adjustment only)
EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
• When passing an endo-therapy 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 knob(s)
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 (the
GIF-N180 has only the UP/DOWN angulation control knob).
• Do not change the insertion tube's flexibility abruptly.
Otherwise, patient pain, injury, bleeding and/or perforation
can result.
• If the endoscopic image moves suddenly or is lost, while you
are changing the insertion tube's flexibility, stop changing the
flexibility and restore the optimal field of view. Moving the
flexibility adjustment ring without a clear endoscopic image
may cause patient pain, injury, bleeding and/or perforation.
• If the patient complains of pain, while you are changing the
insertion tube's flexibility, stop changing the flexibility and
ensure the safety of the patient.
• If the rigidity of the insertion tube has to be increased during
an examination, confirm that there are no loops or excessive
bends in the insertion tube (using fluoroscopy, if necessary)
before increasing its rigidity. If the force required to turn the
flexibility adjustment ring is greater during the procedure than
it was when inspecting the endoscope, it may mean that the
insertion tube is excessively bent inside the patient. In this
case, straighten the insertion tube as much as possible
before attempting to increase the rigidity. Failure to do so
may cause patient pain, injury, bleeding and/or perforation.
