6. Upon insertion into the sheath or cannula, carefully align the
endoscope with the appropriate instruments to avoid scratching the
objective lens and bending the shaft.
CLEANING and STERILIZATION
Pre-Rinsing:
1. Disassemble all components from the endoscope including fiber optic
post adapters.
2. Soak for 3 minutes in warm water and a neutral pH enzymatic pre-wash
solution to soften and remove biological debris (prolonged soaking may
be detrimental to components).
3. Use a tray designed for endoscopes. Avoid contact with dissimilar
equipment to avoid damage to optical surfaces.
Washing:
1. Instruments should be submerged in warm water with an appropriate
neutral pH detergent.
2. Carefully clean with a soft bristled brush or sponge only. Take care not
to damage optical surfaces.
3. Do not place endoscopes in an ultrasonic cleaner or washer-sterilizer.
Rinsing:
1. Rinse all equipment in clean, clear, non-saline water to remove all
cleansing residue.
2. Carefully dry endoscope with soft cloth to ensure clean lenses.
Removing Deposits:
Due to insufficient cleaning or foreign matter in steam during the autoclave
process, deposits may develop on the objective lens (distal end), ocular
lens (proximal lens), and/or the fiber optic post. To remove the deposits,
please follow the recommended steps outlined below:
1. Moisten a cotton-tipped swap with water. Dip the moistened swab in
the aluminum oxide powder (described below).
2. Gently press the swab onto the optical surface to be cleaned and scrub
the window in a circular motion.
3. Rinse the optical surfaces with distilled water to remove any remaining
powder.
4. If stains are still present, carefully clean the lenses or fiber optic post
with a cotton swab and isopropyl alcohol.
NOTE: The aluminum oxide powder can be ordered separately under
catalog T0001, “Endoscope Cleaning Kit.”
Steam Sterilization
Precaution: Prior to sterilization, disassemble all fiber optic post
adapters (see illustration).
1. Autoclavable endoscopes have “AUTOCLAV” clearly marked
on the body of the endoscope. Only endoscopes marked “AUTOCLAV”
are suitable for steam sterilization.
2. After the recommended cleaning procedure is completed, sterilize
using the following parameters.
Double wrap instruments using FDA cleared sterilization wrap.
3. Prepare endoscopes such that all surfaces have direct contact with steam.
