For more information on combining the endoscope with particular EndoTherapy accessories, refer to
“
 Compatible EndoTherapy accessories” on page 86 and the instruction manuals for the accessories.
Also, refer to their respective instruction manuals for operating the accessories.
WARNING
• When using EndoTherapy accessories, keep the distance between the distal end
of the endoscope and the mucous membrane greater than the endoscope’s
minimum visible distance so that the EndoTherapy accessory remains visible in the
endoscopic image. If the distal end of the endoscope is placed closer than its
minimum visible distance, the position of the accessory cannot be seen in the
endoscopic image. This could cause serious patient injury and/or equipment
damage. The minimum visible distance depends on the type of endoscope being
used. Refer to Section 2.2, “Specifications”.
• When inserting or withdrawing an EndoTherapy accessory, confirm that its distal
end is closed or completely retracted into the sheath. Insert or withdraw the
EndoTherapy accessory slowly and straight into or from the slit of the biopsy valve.
Otherwise, the biopsy valve or instrument channel may be damaged and pieces of
it could fall off. It may cause patient injury.
• If insertion or withdrawal of EndoTherapy accessories is difficult, straighten the
bending section as much as possible without losing the endoscopic image.
Inserting or withdrawing EndoTherapy accessories with excessive force may
damage the instrument channel or EndoTherapy accessories and could cause
some parts to fall off and/or cause patient injury.
• If the distal end of an EndoTherapy accessory is not visible in the endoscopic
image, do not open the distal end of the EndoTherapy accessory. This could cause
patient injury, bleeding, perforation, and/or equipment damage.
• If the EndoTherapy accessory cannot be withdrawn from the endoscope, close the
tip of the EndoTherapy accessory or retract the tip of the EndoTherapy accessory
into its sheath. Then carefully withdraw both the endoscope and the EndoTherapy
accessory together while observing the endoscopic image. Inserting or withdrawing
EndoTherapy accessories with excessive force may damage the instrument
channel or EndoTherapy accessories and/or cause patient injury.
• Do not use the channel cleaning brush for cytologic tissue sampling or other
diagnostic or therapeutic purposes. Patient injury, cross-contamination, and/or
equipment damage may occur.
• Do not switch between WLI observation mode and NBI observation mode while
using an EndoTherapy accessory. The endoscopic image may be disturbed while
switching between WLI observation mode and NBI observation mode. This could
cause patient injury, bleeding, and/or perforation.
