• Do not use a guidewire when its outer surface is damaged,
ripped or torn. Leakage current can be discharged from
damaged parts of the guidewire, which could cause burns to
the patient, operator and/or assistant, damage the
endoscope, equipment and/or endo-therapy accessory.
• Insert and withdraw a wire guided type endo-therapy
accessory slowly and carefully when the guidewire is locked
in the guidewire-locking groove at the distal end of
endoscope. If the endo-therapy accessory is withdrawn or
inserted along the guidewire with excessive force or rapidly
while the guidewire is locked, the following phenomena may
occur. Also do not move the guidewire while it is locked at the
distal end of the endoscope. Otherwise, the following
phenomena may occur.
