Indicates additional helpful information.
Warnings and cautions
Follow the warnings and cautions given below when handling this instrument.
This information is to be supplemented by the warnings and cautions given in
each chapter.
•
After using this instrument, reprocess and store it according
to the instructions given in the endoscope’s companion
reprocessing manual whose cover lists the model of your
endoscope. Using improperly or incompletely reprocessed or
stored instruments may cause patient cross-contamination
and/or infection.
•
Before endoscopy, remove any metallic objects (watch,
glasses, necklace, etc.) from the patient. If performing
high-frequency cauterization becomes necessary while the
patient wears a metallic object, it may cause burns on the
patient in areas around the metallic object.
•
Do not strike, bend, hit, pull, twist, or drop the endoscope’s
distal end, insertion tube, bending section, control section,
universal cord, or endoscope connector of the endoscope
with excessive force. The endoscope may be damaged and
could cause patient injury, burns, bleeding and/or
perforations. It could also cause parts of the endoscope to
fall off inside the patient.
•
When performing transnasal insertion of the GIF-N180,
please follow the cautions below.
− The shape and size of the nasal cavity and its suitability
for transnasal insertion may vary from patient to patient.
No endoscope, including this one, can always be inserted
transnasally with all patients. Before proceeding, always
be sure to confirm that transnasal insertion is possible
with the patient. Otherwise, operator and/or patient injury
can result, or the endoscope could become lodged and be
difficult to withdraw.
6
EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
Page 11
Important Information — Please Read Before Use
− Transnasal insertion is accompanied by the risk of
inflammation of the nasal cavity. If this happens, the nasal
passage will be constricted, making it more difficult to
withdraw the endoscope. In this case, do not use force to
withdraw the endoscope because patient injury such as
bleeding or perforation may result.
− Transnasal insertion is accompanied by the risk of
bleeding in the nasal cavity. Be sure to be prepared to
deal with any bleeding. When withdrawing the
endoscope, observe the inside of the nasal cavity to
ensure that there is no bleeding. Even when the
endoscope has been withdrawn without bleeding, do not
allow the patient to blow his or her nose strongly because
this could cause it to start bleeding.
− Before transnasal insertion, apply the appropriate
pretreatment and lubrication to the patient to enlarge the
nasal cavity. Otherwise, operator and/or patient injury can
result or the endoscope could become lodged and be
difficult to withdraw. When applying a pretreatment agent
through a tube, insert the tube into the same path as the
path planned for the endoscope insertion. Otherwise, the
treatment will have no effect. The effects of the
pretreatment agent and lubricant will decrease the longer
the procedure lasts. Apply the pretreatment agent or
lubricant as required during the procedure – for example,
when withdrawal seems to be difficult.
− Transnasal insertion of the endoscope should be
performed carefully. If resistance to insertion is felt, or the
patient reports pain, stop insertion immediately.
Otherwise, operator and/or patient injury can result or the
endoscope could become lodged and be difficult to
withdraw.
− If it becomes impossible to withdraw the transnasally
inserted endoscope, pull its distal end out of the mouth,
cut the flexible tube using wire cutters, and after ensuring
that the cut section will not injure the body cavity or nasal
cavity of the patient, withdraw the endoscope carefully.
Therefore, always prepare wire cutters in advance.
•
Never perform angulation control forcibly or abruptly. Never
forcefully pull, twist or rotate the angulated bending section.
Patient injury, bleeding and/or perforation can result. It may
also become impossible to straighten the bending section
during an examination.

•
Never insert or withdraw the endoscope’s insertion tube
while the bending section is locked in position. Patient injury,
bleeding and/or perforation can result.
•
Never perform flexibility adjustment, operate the bending
section, feed air or perform suction, insert or withdraw the
endoscope’s insertion tube, or use endo-therapy accessories
without viewing the endoscopic image. Patient injury,
bleeding and/or perforation can result.
•
Never perform flexibility adjustment, operate the bending
section, feed air or perform suction, insert or withdraw the
endoscope’s insertion tube, or use endo-therapy accessories
while the image is frozen. Patient injury, bleeding and/or
perforation can result.
•
Regardless of the flexibility of the endoscope’s insertion tube,
never insert or withdraw the insertion tube abruptly or with
excessive force. Patient injury, bleeding and/or perforation
can result.
•
Never insert or withdraw the endoscope’s insertion tube, use
endo-therapy accessories while the image is magnified.
Patient injury, bleeding and/or perforation can result (only
when using the image magnification of the video system
center CV-180).
•
Do not touch the light guide of the endoscope connector
immediately after removing it from the light source because it
is extremely hot. Operator or patient burns can result.
•
When the endoscopic image does not appear on the monitor,
the CCD may have been damaged. Turn the video system
center OFF immediately. Continued power supply in such a
case will cause the distal end to become hot and could cause
operator and/or patient burns.
•
If it is difficult to insert the endoscope, do not forcibly insert
the endoscope; stop the endoscopy. Forcible insertion can
result in patient injury, bleeding and/or perforation.
•
When combining the endoscope with a splinting tube, there is
the risk of perforation or bleeding due to entanglement of the
mucous membrane, or of the tube to becoming separated
from the endoscope and remaining in the body. Before use,
be sure to read the instruction manual for the splinting tube to
fully understand its characteristics.

Examples of inappropriate handling
Details on clinical endoscopic technique are the responsibility of trained
specialists. Patient safety in endoscopic examinations and endoscopic treatment
can be ensured through appropriate handling by the physician and the medical
facility. Examples of inappropriate handling are described below;
•
Over-insufflating the lumen may cause patient pain, injury, bleeding
and/or perforation.
•
Applying suction with the distal end in prolonged contact with the
mucosal surface, with higher suction pressure than required or with
prolonged suction time may cause bleeding and/or lesions.
•
The endoscope has not been designed for use in retroflexed
observation in parts of the body other than the stomach. Performing
retroflexed observation in a narrow lumen may make it impossible to
straighten and/or withdraw the endoscope. Retroflexed observation in
parts of the body other than the stomach should be performed only
when the usefulness of doing so is determined to be greater than the
risk that is posed to the patient.
•
Inserting, withdrawing and using endo-therapy accessories without a
clear endoscopic image may cause patient injury, burns, bleeding
and/or perforation.
•
Inserting or withdrawing the endoscope, feeding air, applying suction or
