Function checks

Risk to patient due to incorrectly displayed image!
►
Remove any contaminations on the optical sur-
faces (camera head) before and during the pro-
WARNING
cedure. Clean the endoscope tip with a cloth
soaked in alcohol (70 % ethanol) or with a neu-
tral cleaning agent.
►
Prior to application and after changing the set-
tings, check the correct display of the live
image. If necessary, perform white balance.
Risk to patient and user from functional failure or
electric shock!
►
WARNING Use only dry components (e.g. plug connector
for camera control unit, optical lens).
Note
Only perform the surgical procedure if all of the components being used are
in a flawless condition.
Note
Before each use, after a power failure or any interruption, the functionality
of all connected devices must be checked and all connections must be
checked to see they are correct.
Note
The endoscope image must be focused, bright and clean at an appropriate
working distance.
Note
Do not continue to use damaged products.

Safe operation

Risk of burns due to development of heat at the tip
of the endoscope!
►
Do not put down the endoscope on the patient
WARNING
during use.
►
In the patient's abdominal cavity, always leave a
sufficient distance between the optical lens and
the tissue surfaces and mucous membranes of
the patient.
►
Use automatic light intensity control or set the
light source so that a bright, well-lit image is
visible with the lowest possible light intensity.
►
Switch off the light source if the illumination is
no longer needed or if the endoscope is out of
the patient for a longer period of time.
Excessive temperatures in combination with light sources
Light sources, especially high-power light sources, emit large amounts of
light energy and thermal energy. The light guide connector and the distal
end of the endoscope may therefore become extremely hot.
Risk of injury due to excessive temperature!
►
Do not touch the light guide connector or distal
end of the endoscope during use or immediately
WARNING
after use.
Risks from use of light sources:
■
Irreversible tissue damage or unwanted coagulation to the patient or
user
■
Burns or thermal damage to surgical equipment (e.g. surgical drapes,
plastic materials, etc.)
■
If the light source fails during use, this may endanger the patient.
Therefore keep an operationally ready replacement light source on
hand.
Safety precautions
►
Do not illuminate the inside of the patient for longer than necessary
with the light source.
►
Use the automatic light intensity control or set the light source so that
a bright, well-lit image is visible with the lowest possible light inten-
sity.
►
Do not allow the distal end of the endoscope or light guide connector
to come into contact with patient tissue or with combustible or heat-
sensitive materials.
►
Do not touch the distal end of the endoscope.
►
Remove contaminations on the distal end surface or light emission sur-
face.
Risk of injury and/or malfunction!
►
Always carry out a function check prior to using
the product.
WARNING
Risk of injury from burns and unwanted deep pen-
etration and risk of damage to product!
►
Only switch on high frequency current when the
WARNING
corresponding applied part (electrode) can be
seen through the endoscope and there is no
contact between the two.
Risk of infection due to contamination of the ster-
ile area!
►
Fix the camera cable (unsterile) with sterile
WARNING
cover (sterile) sufficiently nearby in the opera-
tion area.
