ULTRASOUND GASTROVIDEOSCOPE GF-UCT180
• Never insert or withdraw the endoscope under any of the
following conditions. Otherwise, patient injury, bleeding,
and/or perforation can result.
− While the EndoTherapy accessory extends from the distal
end of the endoscope.
− While the bending section is locked in position.
− Insertion or withdrawal with excessive force.
− Insertion or withdrawal while the forceps elevator is
raised.
• If any of the following phenomena occur during an
examination, immediately stop the examination and withdraw
the endoscope from the patient as described in Section 13.2,
“Withdrawal of the endoscope with an irregularity” on
page 218.
− Should any irregularity be observed with the functionality
of the endoscope.
− If the endoscopic image on the monitor disappears or
freezes unexpectedly.
− If the angulation control knob is locked.
− If the angulation control mechanism is not functioning
properly.
Continued use of the endoscope under these conditions
could result in patient injury, bleeding, and/or perforation.
• If an abnormal endoscopic image or function occurs, but
quickly corrects itself, the endoscope may have
malfunctioned. In this case, stop using the endoscope
because the irregularity can occur again and the endoscope
may not return to its normal condition. Therefore, stop the
examination immediately and slowly withdraw the endoscope
while viewing the endoscopic image. Otherwise, patient
injury, bleeding, and/or perforation can result.
• The endoscopic image may be disturbed while switching
between WLI observation mode and NBI observation mode.
Therefore, do not perform an endoscopic operation or
treatment while switching between WLI observation mode
and NBI observation mode. Otherwise, injury in the body
cavity may result.
