Operation of endo-therapy accessories

instruction manual.
Withdrawal of endo-therapy accessories
Withdraw the endo-therapy accessory slowly while the tip of the endo-therapy
accessory is closed and/or retracted into its sheath.
EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
• When the tip of the endo-therapy accessory extends
approximately 1 cm from the distal end of the endoscope, the
accessory will appear in the endoscopic image.
• When the accessory appears in the endoscopic image, it
may also reflect the light from the endoscope and/or cast its
shadow in the endoscopic image. This does not indicate a
malfunction (for GIF-N180 only).
• Patient debris might spray when the endo-therapy
accessories are withdrawn from the biopsy valve. To prevent
this, hold a piece of gauze around the accessory and the
biopsy valve during withdrawal.
• Do not withdraw the endo-therapy accessory if the tip is open
or extended from its sheath; patient injury, bleeding,
perforation and/or instrument damage may occur.
• Withdraw the endo-therapy accessory slowly and straight out
of the biopsy valve. Otherwise, the valve's slit and/or hole
could be damaged. This can reduce the efficacy of the
endoscope's suction system, and may leak or spray patient
debris or fluids, posing an infection-control risk.
• If the endo-therapy accessory cannot be withdrawn from the
endoscope, close the endo-therapy accessory and/or retract
it into its sheath, then carefully withdraw both the endoscope
and the endo-therapy accessory together under endoscopic
observation. Take care not to cause tissue trauma.
