Using EndoTherapy accessories

EVIS EXERA II TJF TYPE Q180V OPERATION MANUAL
For more information on combining the endoscope with particular EndoTherapy
accessories, refer to the "System chart" in the Appendix and the instruction
manuals for the accessories.
• 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 own minimum visible distance, the
position of the accessory cannot be seen in the endoscopic
image, which could cause serious patient injury and/or
equipment damage. The minimum visible distance depends
on the type of endoscope being used. Refer to Section 2.3,
"Specifications" on page 16.
• When inserting or withdrawing an EndoTherapy accessory,
confirm that its distal end is closed or completely retracted
into the sheath. Slowly insert or withdraw the EndoTherapy
accessory straight into or from the slit of the biopsy valve.
Otherwise, the biopsy valve may be damaged and pieces of it
could fall off.
• 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 or extend
the needle of the instrument. This could cause patient injury,
bleeding, perforation, and/or equipment damage.
• 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.
