Phase I
►
Clean the product in an ultrasonic cleaning bath (frequency 35 kHz) for at least 15 min. Ensure that all accessible
surfaces are immersed and acoustic shadows are avoided.
►
Clean the product with a suitable cleaning brush in the solution until all discernible residues have been removed
from the surface.
►
If applicable, brush through non-visible surfaces with an appropriate cleaning brush for at least 1 min.
►
Mobilize non-rigid components, such as set screws, links, etc. during cleaning.
►
Thoroughly rinse through these components with the cleaning disinfectant solution (at least five times), using a
disposable syringe.
Phase II
►
Rinse/flush the product thoroughly (all accessible surfaces) under running water.
►
Mobilize non-rigid components, such as set screws, joints, etc. during rinsing.
►
Drain any remaining water fully.
Phase III
►
Fully immerse the product in the disinfectant solution.
►
Mobilize non-rigid components, such as set screws, joints, etc. during rinsing.
►
Rinse lumens at least five times at the beginning of the exposure time with an appropriate disposable syringe.
Ensure that all accessible surfaces are moistened.
Phase IV
►
Rinse/flush the product thoroughly (all accessible surfaces) under running water.
►
Mobilize non-rigid components, such as set screws, joints, etc. during final rinse.
►
Rinse lumens with an appropriate disposable syringe at least five times.
►
Drain any remaining water fully.
Phase V
►
Dry the product in the drying phase with suitable equipment (e.g. cloth, compressed air), see Validated cleaning
and disinfection procedure.
Mechanical cleaning/disinfection with manual pre-cleaning
Note
The cleaning and disinfection device must be of tested and approved effectiveness (e.g. FDA approval or CE mark
according to DIN EN ISO 15883).
Note
The cleaning and disinfection device used for processing must be serviced and checked at regular intervals.

Mechanical alkaline cleaning and thermal disinfecting
Machine type: single-chamber cleaning/disinfection device without ultrasound
D–W:
Drinking water
FD–W:
Fully desalinated water (demineralized, low microbiological contamination: drinking water quality
at least)
*Recommended: BBraun Helimatic Cleaner alkaline
►
Check visible surfaces for residues after mechanical cleaning/disinfecting.
Inspection, maintenance and checks
►
Allow the product to cool down to room temperature.
►
Lubricate the product at the labeled points 2.
►
After each complete cleaning, disinfecting and drying cycle, check that the product is dry, clean, operational, and
free of damage (e.g. broken insulation or corroded, loose, bent, broken, cracked, worn, or fractured components).
►
Dry the product if it is wet or damp.
►
Repeat cleaning and disinfection of products that still show impurities or contamination.
►
Check that the product functions correctly.
►
Immediately put aside damaged or inoperative products and send them to Aesculap Technical Service, see Tech-
nical Service.
►
Check for compatibility with associated products.
Packaging
►
Place the product in its holder or on a suitable tray. Ensure that all cutting edges are protected.
►
Pack trays appropriately for the intended sterilization process (e.g. in Aesculap sterile containers).
►
Ensure that the packaging provides sufficient protection against recontamination of the product during storage.
Steam sterilization
►
Check to ensure that the sterilizing agent will come into contact with all external and internal surfaces (e.g. by
opening any valves and faucets).
►
Validated sterilization process
–
Steam sterilization using fractional vacuum process
–
Steam sterilizer according to DIN EN 285 and validated according to DIN EN ISO 17665
–
Sterilization using fractional vacuum process at 134 °C/holding time 5 min
►
When sterilizing several products at the same time in a steam sterilizer, ensure that the maximum load capacity
of the steam sterilizer specified by the manufacturer is not exceeded.
Sterilization for the US market
■
Aesculap advises against sterilizing the device by flash sterilization or chemical sterilization.
■
Sterilization may be accomplished by a standard prevacuum cycle in a steam autoclave.
To achieve a sterility assurance level of 10
-6
, Aesculap recommends the following parameters:
*Aesculap has validated the above sterilization cycle and has the data on file. The validation was accomplished in an
Aesculap sterile container cleared by FDA for the sterilization and storage of these products. Other sterilization cycles
may also be suitable, however individuals or hospitals not using the recommended method are advised to validate
any alternative method using appropriate laboratory techniques. Use an FDA cleared accessory to maintain sterility
after processing, such as a wrap, pouch, etc.
Storage
►
Store sterile products in germ-proof packaging, protected from dust, in a dry, dark, temperature-controlled area.

CAUTION
Damage (metal seizure/friction corrosion) to the product caused by insufficient
lubrication!
►
Prior to function checks, lubricate moving parts (e.g. joints, pusher compo-
nents and threaded rods) at the marked lubrication points, using maintenance
oil suitable for the respective sterilization process (e.g. for steam sterilization:
Aesculap STERILIT® I oil spray JG600 or STERILIT® I drip lubricator JG598).
CAUTION
Damage (metal cold welding /friction corrosion) to the product caused by insuf-
ficient lubrication!
►
Prior to function checks, lubricate both locking parts at the labeled points with
maintenance oil suitable for the respective sterilization process (e.g. for steam
sterilization: STERILIT® I oil spray JG600 or STERILIT® I drip lubricator JG598).
