Validated reprocessing procedure

7.1

General safety notes

Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for reprocessing. Note For patients with Creutzfeldt-Jakob disease (CJD), suspected CJD, or possible variants of CJD, observe the relevant national regulations concerning the reprocessing of products. Note It should be noted that successful reprocessing of this medical device can only be guaranteed following prior validation of the reprocessing method. The operator/reprocessing technician is responsible for this. The specified chemistry was used for validation.

7.6

Mechanical cleaning/disinfection with manual pre-cleaning

Note As a matter of principle, the efficacy of the cleaning and disinfection device must be certified (e.g. in accordance with EN ISO 15883). Note The cleaning and disinfection machine used for processing must be serviced and checked at regular intervals.

Phase I ► Clean the product in the solution using a suitable cleaning brush until no residue is visible on the surface. ► If applicable, use a suitable cleaning brush to brush any surfaces that are not visible for at least 1 min. ► Mobilize non-rigid components, such as set screws and hinges, during cleaning. ► Then flush these areas thoroughly at least five times with the cleaning disinfectant solution using a disposable syringe (20 ml). Phase II ► Rinse/flush the instrument thoroughly (all accessible surfaces) under running water. ► Mobilize non-rigid components, such as set screws and hinges, during rinsing.

General information

Dried and hardened or clotted surgical residues can complicate cleaning or render it ineffective and cause corrosion. Therefore, do not exceed a period of 1h between use and processing, make sure pre-cleaning temperatures are <45°C to prevent clotting, and do not use disinfectants that can cause clotting (active ingredient: aldehyde, alcohol). Excessive neutralizing agents or basic cleaners may result in a chemical attack and/or fading and the laser marking becoming unreadable either visually or by machine. Residues containing chlorine or chlorides, e.g., in surgical residues, medicines, saline solutions, and in the service water used for cleaning, disinfection, and sterilization, will cause corrosion damage (pitting, stress corrosion) and result damage to metallic products. These must be removed by rinsing thoroughly with demineralized water and then drying. Perform additional drying, if necessary. Only process chemicals that have been tested and approved (e.g. VAH or FDA approval or CE mark) and which are compatible with the product’s materials according to the chemical manufacturers’ recommendations may be used for processing the product. All the chemical manufacturer's application specifications must be strictly observed. Failure to do so can result in the following problems: ■ Material damage such as corrosion, cracks, fracturing, premature aging, or swelling. ► Do not use metal cleaning brushes or other abrasives that would damage the product surface and could cause corrosion ► For detailed information on hygienically safe and material-friendly/careful processing, please refer to www.a-k-i.org Header "AKI-Brochures", "Red brochure".

Reusable products

There are no known effects of processing resulting in damage to the product. The product can be re-used up to 200 times with proper care and if it is undamaged and clean. Any additional reuse falls under the responsibility of the user. Careful visual and functional testing prior to next use is the best way to identify a malfunctioning product.

D–W: Drinking water DI–W: Deionized water 1) The cleaning and disinfection devices listed below were used to verify cleanability: Miele 7836 CD 2) Prion-deactivating detergent (see Specifications Dr. Weigert neodisher® SeptoClean) ► Place the product in a tray that is suitable for cleaning (avoiding rinsing blind spots) ► Place instruments in the tray with their hinges open. ► Connect the lumens and channels of individual parts directly to the injector unit's special flushing connector. ► Check visible surfaces for residues after mechanical cleaning/disinfecting.

7.7

Inspection, maintenance and checks

CAUTION

Damage (metal seizure/friction corrosion) to the product caused by insufficient lubrication! ► Prior to function checks, lubricate moving parts (e.g. joints, pusher components and threaded rods) with 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).

► Allow the product to cool down to room temperature. ► 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.

7.8

Packaging

► Appropriately protect products with fine working tips. ► Store products with ratchet locks fully opened or locked no further than in the first notch. ► 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.

7.9

Steam sterilization

Note To avoid breakage due to stress crack corrosion, sterilize the product with the lock fully open or locked no further than on the first ratchet tooth. ► 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 18 minutes for prion inactivation ► 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.

7.10 Storage ► Store sterile products in germ-proof packaging, protected from dust, in a dry, dark, temperature-controlled area.
