Insertion of endo-therapy accessories into the endoscope
EVIS EXERA TJF TYPE 160VR OPERATION MANUAL
•
Do not insert or withdraw an endo-therapy accessory by
force when the forceps elevator is raised to its maximum
height. The instrument channel and/or the endo-therapy
accessory may be damaged and patient injury, bleeding
and/or perforation can result. If the endo-therapy accessory
cannot be inserted or withdrawn, move the elevator control
lever in the opposite direction of "
elevator and insert or withdraw the endo-therapy accessory.
•
When using a biopsy forceps with a needle, confirm that the
needle is not bent excessively. A bent needle could protrude
from the closed cups of the biopsy forceps. Using such a
biopsy forceps 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channel, or if the injector is inserted or withdrawn while the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 endo-therapy accessories forcibly or abruptly.
Otherwise, the endo-therapy accessory may extend from the
distal end of the endoscope abruptly, which could cause
patient injury, bleeding and/or perforation.
•
When using the endo-therapy accessory with the cap of the
biopsy valve detached, it is easier to insert the accessory.
But, as a result, it can reduce efficacy of the endoscope's
suction system, and may leak or spray patient debris or
fluids, posing an infection-control risk. When not using the
endo-therapy accessory, attach the cap to the main body of
the biopsy valve.
•
When the cap of the biopsy valve is detached, it may cause
patient debris or fluids to leak or spray from the endoscope,
posing an infection-control risk. When the valve is uncapped,
place a piece of sterile gauze over it to prevent leakage.
