Insertion of EndoTherapy accessories into the endoscope
EVIS EXERA II TJF TYPE Q180V OPERATION MANUAL
• Do not inflate air or a nonflammable gas excessively into the
patient. This could cause gas embolism.
• When using a biopsy forceps with a needle, confirm that the
needle is not excessively bent. A bent needle could protrude
from the closed cups of the biopsy forceps. Using biopsy
forceps with a protruding needle could damage the
instrument channel and/or cause patient injury.
• When using an injector, be sure not to extend or retract the
needle from the catheter of the injector until the injector is
extended from the distal end of the endoscope. The needle
could damage the instrument channel if extended inside the
channel, or if the injector is inserted or withdrawn while the
needle is extended.
• Do not insert EndoTherapy accessories forcibly or abruptly.
Otherwise, the EndoTherapy accessory may extend from the
distal end of the endoscope abruptly, which could cause
patient injury, bleeding, and/or perforation.
• When the biopsy valve's cap is detached from the main body,
it is easier to insert an EndoTherapy accessory into the
instrument channel port (see Figure 3.9 on page 30).
However, the open biopsy valve, after withdrawing an
EndoTherapy accessory, can reduce the efficacy of the
endoscope's suction system and may leak or spray patient
debris or fluids, posing an infection control risk. When not
using an EndoTherapy accessory, attach the cap to the main
body of the biopsy valve.
• When the biopsy valve's cap is detached from the main body,
it may cause patient debris or fluids to leak or spray from the
endoscope, posing an infection control risk. When the biopsy
valve's cap has to be detached, place a piece of sterile gauze
over it to prevent leakage.
• Do not let the EndoTherapy accessory hang down from the
biopsy valve. Doing so can create a space between the
accessory and the valve's slit or hole. This can damage the
valve, which can reduce the efficacy of the endoscope's
suction system and may leak or spray patient debris or fluids,
posing an infection control risk.
