Attaching the distal cover
EVIS EXERA TJF TYPE 160VR OPERATION MANUAL
•
Never use the endoscope unless the distal cover is properly
attached to the distal end. If the distal cover is not attached
correctly, it may slip off or fall off the distal end during the
examination. This could result in thermal injury when the
endoscope is used with high-frequency endo-therapy
accessories. And, continuing the examination after the distal
cover has fallen off may cause patient injury by the exposed
distal end of the endoscope.
•
If a distal cover with cracks or pinholes is used, it could fall off
during the examination and/or, it may cause thermal injury
because an electric current leaks from cracks or pinholes
when high-frequency cauterization treatment is performed.
Never use a distal cover with cracks or pinholes but replace it
with a new one.
•
Do not put silicone oil, olive oil, or products containing
petroleum-based lubricants (e.g.Vaseline) on the distal cover
or the distal end. Silicone oil may cause deterioration of the
distal cover. If the distal cover is damaged this way, it may
slip off or fall off during the examination. Continuing the
examination after the distal cover has fallen off may cause
patient injury by the exposed distal end of the endoscope. It
could also result in thermal injury when used in combination
with high-frequency endo-therapy accessories.
When attaching the distal cover, gently hold the bending
section as close to the distal end as possible. Forcefully
grasping other parts of the bending section can damage the
mechanism of the bending section or deform its covering.
