EVIS LUCERA GIF/CF/PCF TYPE 260 Series OPERATION MANUAL
• 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.
While the image is magnified (when using the GIF-H260Z,
CF-H260AZL/I, PCF-Q260AZI or using the image
magnification function of video system center CV-260SL,
CV-260).
• 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, bleeding,
and/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Even when the endoscope has been withdrawn without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, 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’s 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.
