4.2 Insertion and Observation
WARNING
To avoid the potential for patient injury including perforation, do not
apply excessive force of the ultrasonic endoscope or endotherapy
device against mucosal surfaces. Only advance the endotherapy
device while viewing the endoscopic image.
During ultrasonic procedures in which a balloon is not used, do not
fully depress the suction valve and do not attempt to aspirate patient
material into/through the balloon evacuation channel. Doing so can
result in partial or complete clog of the narrow balloon evacuation
channel, especially if the ultrasonic endoscope is not cleaned
immediately after each procedure and if not reprocessed as per
FUJIFILM recommendations. Once the balloon evacuation channel is
clogged, it cannot be cleaned, disinfected or sterilized properly and can
be a source of infection.
CAUTION
Take extreme care when inserting the ultrasonic endoscope into the
oral cavity. Otherwise, it may cause pain to the patient.
Do not forcibly advance or withdraw the ultrasonic endoscope into/
from the patient. It may cause damage to the body lumen, bleeding or
perforation.
Do not angulate the bending section forcibly or operate it quickly. It
may cause damage to the body lumen, bleeding or perforation.
During an observation, do not perform close observation for an
extended period of time. Use the ultrasonic endoscope with a minimum
necessary amount of brightness and time while maintaining an
appropriate distance. When the shutter speed is set to "HIGH", take
care not to set the brightness level too high. Thermal energy created
by illumination may cause burn injury.
For details on the settings, refer to the operation manual of the light
source and processor in use. If the brightness level is high, the
temperature at the distal end may exceed 41°C. Do not allow the distal
end to remain in contact with the same site for an extended period of
time. It may cause burn injury.
