Using endo-therapy accessories
For more information on combining the endoscope with particular endo-therapy
accessories, refer to the “System chart” in the Appendix and the instruction
manuals of the accessories. Refer to the instruction manuals of the accessories
for instructions on how to operate them properly.
• When using endo-therapy 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 endo-therapy 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,
which could cause serious injury and/or equipment damage.
The minimum visible distance depends on the type of
endoscope being used. Refer to Section 2.3, “Specifications”.
• When inserting or withdrawing an endo-therapy accessory,
confirm that its distal end is closed or retracted into the
sheath completely. Slowly insert or withdraw the
endo-therapy accessory straight into/from the slit of the
biopsy valve. Otherwise, the biopsy valve may be damaged
and piece of it could fall off.
• If the insertion or withdrawal of endo-therapy accessories is
difficult, straighten the bending section as much as possible
without losing the endoscopic image. Inserting or
withdrawing endo-therapy accessories with excessive force
may damage the instrument channel or endo-therapy
accessories, cause some parts to fall off and/or cause patient
injury.
• If the distal end of an endo-therapy accessory is not visible
within the endoscopic image, do not open the distal end or
extend needle of the instrument. This could cause patient
injury, bleeding, perforation and/or equipment damage.
• If an endo-therapy accessory cannot be withdrawn from the
endoscope, close the tip of the endo-therapy accessory or
retract the tip of the endo-therapy accessory into its sheath
and slowly withdraw the endoscope while observing the
endoscopic image.
