• When using EndoTherapy accessories, always use the
widest possible angle. When the image is magnified, it may
not be possible to see the position of the accessory in the
endoscopic image. This could cause patient injury, bleeding,
and/or perforation (when using the image magnification
function of video system center CV-180).
• Do not insert EndoTherapy accessories without the forceps
elevator being raised. If they are inserted without the forceps
elevator being raised, the accessory cannot be observed in
the endoscopic image and it may cause patient injury.
• Check the movement of the EndoTherapy accessory by
operating the elevator control lever several times to raise the
forceps elevator. Otherwise, the EndoTherapy accessory
may move unexpected directions, and patient injury,
bleeding, and/or perforation may result.
• Locate the cutting knife or the cutting wire as central as
possible in the endoscopic image by adjusting the position of
the distal end of endoscope, particularly while performing
papillotomy. When the distal end of EndoTherapy accessory
is positioned in the left or right side of the endoscopic image,
and the elevator control lever is operated, the EndoTherapy
accessory may move abruptly, resulting in patient injury,
bleeding, and/or perforation.
• Operate the elevator control lever carefully. Otherwise, the
EndoTherapy accessory may move unexpected directions,
and patient injury, bleeding, and/or perforation may result.
• While raising the forceps elevator, do not insert or withdraw
the EndoTherapy accessory with excessive force, open or
close the distal end of the EndoTherapy accessory, or extend
the needle of the instrument. This could damage the
instrument channel and/or the EndoTherapy accessory and
could cause patient injury, bleeding, and/or perforation. If the
EndoTherapy accessory cannot be inserted or withdrawn,
the distal end of the EndoTherapy accessory cannot be
opened or closed, or the needle of the instrument cannot be
extended, move the elevator control lever in the opposite
direction of the "
