3. DIRECTIONS FOR USE
3-1. PRETREATMENT
1) The patient should be prepared in your normal endoscopy regimen.
3-2. INSERTION AND WITHDRAWAL
1) Slowly insert the scope under direct vision.
2)
(SCOPES TO BE INTRODUCED TRANSORALLY)
When the distal end of the scope is passed through the
pharynx, the patient should be gently biting down on the
bite block to maintain the bite block’s position during the
procedure.
3) Adjust the intensity of the video processor to obtain a
brightness level suitable for observation.
4) The deflection controls should be used as needed to position the scope. The deflection of the tip should be
done under direct vision in a gentle and deliberate manner.
5) Insufflation can be controlled by the combined use of the air valve or CO
2
valve to increase the amount of
insufflation and the suction control to decrease the level of insufflation. The user may elect to use CO
2
deliv-
ery in lieu of air delivery by using the CO
2
gas adapter (OF-G11) in combination with a special CO
2
/water
valve. (OF-B130)
WARNING:
This instrument should only be used by physicians who have thoroughly studied all the characteristics of
this instrument and who are familiar with the proper techniques of endoscopy. During the procedure,
always wear protective garments such as gloves, gowns, face masks, etc. to minimize the risk of cross
contamination.
BITE BLOCK
WARNING:
The light emission from the endoscope could cause thermal injury. To minimize the risk, use only the
minimum amount of brightness and avoid close stationary viewing and unnecessary prolonged use.
CAUTION:
ANY lack of smooth operation of the deflection controls may be an early indication of internal damage to
and/or part(s) failure within the endoscope’s angulation system. To avoid the potential for malfunction of
the angulation system, do NOT use the endoscope if the angulation mechanism does not operate prop-
erly.
Ensure that the deflection controls can rotate smoothly, that there is no grinding or excess friction within
the angulation system and that the distal bending section bends freely and smoothly.
NEVER APPLY EXCESSIVE FORCE TO THE DEFLECTION CONTROLS!
If during a procedure angulation is lost in any direction such as when “cables snap” (broken pulley wire,
broken angle wire, etc.), do NOT continue to use the instrument and do NOT rotate the deflection con-
trols. Should the angulation system fail for any reason, stop the procedure, release the lock lever and
carefully withdraw the endoscope under direct visualization.
The examples above are indications that service is required to avoid more serious problems with the
angulation control system, including the possibility of a “frozen” distal bending section.
A “frozen” bending section can make instrument extraction from a patient more difficult.
