Endoscopic Accessories
• When using endoscopic accessories, make sure the accessory remains visible in the
endoscopic image. If the position of the accessory cannot be seen in the endoscopic
image, serious patient injury and/or equipment damage may occur.
• When inserting or withdrawing an endoscopic accessory, conrm that its distal end is
closed or completely retracted into the sheath. Make sure to straighten the bending
section as much as possible. Inserting or withdrawing endoscopic accessories with
excessive force may damage the working channel or the endoscopic accessories.
Slowly insert or withdraw the endoscopic accessory straight into or from the slit of the
biopsy valve. Otherwise, the biopsy valve may be damaged and pieces of it could fall
o and/or cause patient injury.
• Do not insert endoscopic accessories without the elevator being raised. If they are
inserted without the elevator being raised, the accessory cannot be observed in the
endoscopic image and may cause patient injury.
• Check the movement of the endoscopic accessory by slowly operating the elevator
control lever several times to raise the elevator. Otherwise, the endoscopic accessory
may move in unexpected directions, and patient injury, bleeding, and/or perforation
may result.
• Locate the endoscopic accessories as central as possible in the endoscopic image
by adjusting the position of the distal end of the endoscope, particularly while
performing papillotomy. When the distal end of the endoscopic accessory is
positioned in the left or right side of the endoscopic image, and the elevator control
lever is operated, the endoscopic accessory may move abruptly, resulting in patient
injury, bleeding, and/or perforation.
• Do not use excessive force when operating, inserting or withdrawing endoscopic
accessories and make sure the accessory is visible on the endoscopic image.
Otherwise, the endoscopic accessory may extend from the distal end of the endoscope
abruptly, which could cause patient injury, bleeding, and/or perforation. Never emit
high-frequency current before conrming that the distal end of the high-frequency
endoscopic accessory is in the endoscope’s eld of view. Also, conrm that the
electrode section and the mucous membrane in the vicinity of the target area are at
an appropriate distance from the distal end of the endoscope. If the high-frequency
current is emitted while the distal end of the endoscopic accessory is not visible or too
close to the distal end of the endoscope, patient injury, bleeding, and/or perforation as
well as equipment damage can result.
• While moving the elevator, do not open or close the distal end of the endoscopic
accessory. This could damage the endoscopic accessory and could cause patient
injury, bleeding, and/or perforation. If the endoscopic accessory cannot be inserted or
withdrawn, the distal end of the endoscopic accessory cannot be opened or closed,
move the elevator control lever in the opposite direction of the "Up" direction to lower
the elevator.
• When the device is used with energized endoscopic devices, leakage current may be
additive. Use only endoscopic devices of type BF or CF. Check the compatibility of the
accessory/endoscopic device before use regarding any criteria for safe use.
Suction
• Avoid aspirating solid matter or thick uids; working channel, suction channel, or
suction valve clogging can occur.
• When aspirating, maintain the suction pressure at the lowest level necessary to
perform the procedure. Excessive suction pressure could cause aspiration of and/or
injury to the mucous membrane. In addition, patient uids could leak or spray from the
biopsy valve, posing an infection control risk.
