the tip of the endo-therapy accessory from its sheath in the
instrument channel. The instrument channel and/or the
endo-therapy accessory may become damaged.

and advance it slowly and straight into the biopsy valve using slow, short
strokes while observing the endoscopic image.
When the tip of the endo-therapy accessory extends
approximately 1 cm from the distal end of the endoscope, the
accessory appears in the endoscopic image.
Operation of endo-therapy accessories
Operate the endo-therapy accessory according to the directions given in its
instruction manual.
Withdrawal of endo-therapy accessories
• Do not withdraw the endo-therapy accessory if the tip is open
or extended from its sheath; patient injury and/or instrument
damage may occur.
• If the endo-therapy accessory cannot be withdrawn from the
endoscope, carefully withdraw both the endoscope and the
endo-therapy accessory together under endoscopic
observation. Take care not to cause tissue trauma.
Withdraw the endo-therapy accessory slowly while the tip of the endo-therapy
