• Do not manipulate the elevator control lever and the insertion
section abruptly while the guidewire is being locked.
Otherwise, patient pain, injury, bleeding, and/or perforation
may result.
• Stop manipulation of the guidewire locking and restore the
optimum field of view if the object is lost from the endoscopic
image and/or the endoscopic image moves suddenly during
the manipulation of the guidewire locking. Manipulation
without the optimum field of view can cause patient pain,
injury, bleeding, and/or perforation.
• If the patient reports pain while the guidewire is being locked
at the distal end of the endoscope, stop locking the guidewire
and ensure patient safety.
• Lock the guidewire at the distal end of the endoscope after
making the insertion section of the endoscope as straight as
possible. Confirm the insertion section with the X-ray image
as required. If the guidewire is locked with the insertion
section excessively bent, the distal end of the endoscope
moves suddenly and patient pain, injury, bleeding, and/or
perforation may result.
• Insert the guidewire into the biliary/pancreatic duct
sufficiently when the guidewire is retained there. If the
guidewire is not locked at the distal end of the endoscope
with sufficient insertion, the guidewire can be withdrawn from
the biliary/pancreatic duct. This may cause patient injury,
bleeding, and/or perforation.
• Insert and withdraw a wire-guided type EndoTherapy
accessory slowly and carefully when the guidewire is locked
in the guidewire-locking groove at the distal end of the
endoscope. If the EndoTherapy accessory is withdrawn or
inserted along the guidewire with excessive force or rapidly
while the guidewire is locked, or the guidewire is moved while
it is locked at the distal end of the endoscope, the following
may occur:
 The guidewire comes off the guidewire-locking groove
 The guidewire penetrates deep inside the patient's body
 The outer surface of the guidewire becomes damaged,

and patient injury, bleeding, and/or perforation can result.
ripped, or torn, and pieces of the outer surface might fall
into the patient's body.
