Insertion of endo-therapy accessories into the endoscope
EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
• When using endo-therapy accessories, always use the
widest possible angle. When the image is magnified, it may
not be possible to see the position of the accessory in the
endoscopic image. This could cause patient injury, bleeding
and/or perforation (when using the image magnification
function of the video system center CV-180).
• When using a distal attachment, the distal end of the
endoscope becomes longer and its outer diameter is larger.
Handle the endoscope carefully so as not to cause
perforation or other patient injury. When performing
endoscopic treatment using this equipment, take extra care.
• 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channel, or if the injector is inserted or withdrawn while the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.
• It is easier to insert an endo-therapy accessory into the
instrument channel port if the biopsy valve's cap is detached
from the main body (see Figure 3.11 on page 45). As a result,
the open biopsy valve 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 endo-therapy accessory, attach the cap to the main
body of the biopsy valve.
