EVIS EXERA II TJF TYPE Q180V OPERATION MANUAL
 The outer surface of the guidewire is damaged, ripped, or
torn, and leakage current can be discharged from
damaged parts of the guidewire, which could cause burns
to the patient, operator and/or assistant, and damage the
endoscope, equipment and/or EndoTherapy accessory.
• Observe the endoscopic image and/or X-ray image to
confirm that the guidewire is locked at the distal end of the
endoscope when withdrawing or inserting a wire-guided type
EndoTherapy accessory. Otherwise, patient injury, bleeding,
and/or perforation can result.
• Do not withdraw the endoscope if the guidewire is stuck in
the guidewire-locking groove at the distal end. Doing so may
result in patient injury, bleeding, and/or perforation. In this
case, insert a wire-guided type EndoTherapy accessory over
the guidewire from its proximal end while observing the
endoscopic image to confirm that the guidewire does not
penetrate patient tissue. When the EndoTherapy accessory
passes through the groove, it removes the guidewire from the
groove. If the guidewire is still stuck in the guidewire-locking
groove, contact Olympus without changing the position of the
instrument.
• The maximum angle of the forceps elevator is slightly
increased compared to duodenoscopes without the assist
function of the guidewire locking, due to the necessity to lock
the guidewire at the distal end. Therefore, EndoTherapy
accessories can be raised higher than with other
duodenoscopes without the assist function of the guidewire
locking. Closely observe the endoscopic image when using
an EndoTherapy accessory with this endoscope, particularly
while performing papillotomy. Do not manipulate the elevator
control lever and/or EndoTherapy accessory without closely
viewing the endoscopic image, as patient injury, bleeding,
and/or perforation can result.
• The elevator control lever is more responsive than
conventional duodenoscopes for more effective locking of the
guidewire, requiring less movement to raise or lower the
forceps elevator. Therefore, carefully observe the endoscopic
image when using EndoTherapy accessories with this
endoscope, particularly when performing papillotomy. Do not
manipulate the elevator control lever and/or EndoTherapy
accessory without carefully observing the endoscopic image,
as patient injury, bleeding and/or perforation may result.
