Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for sterile processing.
Note Mechanical reprocessing should be favored over manual cleaning as it gives better and more reliable results. Note Successful processing of this medical device can only be ensured if the processing method is first validated. The operator/sterile processing technician is responsible for this. The recommended chemistry was used for validation. Note If there is no final sterilization, then a virucidal disinfectant must be used.

Safe handling and preparation CAUTION Federal law restricts this device to sale by, or on order of a physician! ► Ensure that the product and its accessories are operated and used only by persons with the requisite training, knowledge, or experience. ► Read, follow, and keep the instructions for use. ► Use the product only in accordance with its intended use, see Intended use. ► Remove the transport packaging and clean the new product, either manually or mechanically, prior to its initial sterilization. ► Store any new or unused products in a dry, clean, and safe place. ► Prior to each use, inspect the product for loose, bent, broken, cracked, worn, or fractured components. ► Do not use the product if it is damaged or defective. Set aside the product if it is damaged. ► Replace any damaged components immediately with original spare parts.
Dried or affixed surgical residues can make cleaning more difficult or ineffective and lead to corrosion. Therefore the time interval between application and processing should not exceed 6 h; also, neither fixating pre-cleaning temperatures >45 °C nor fixating disinfecting agents (active ingredient: aldehydes/alcohols) should be used. Excessive measures of neutralizing agents or basic cleaners may result in a chemical attack and/or to fading and the laser marking becoming unreadable visually or by machine for stainless steel. 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 in the destruction of stainless steel products. These must be removed by rinsing thoroughly with demineralized water and then drying. 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: ■ Optical changes of materials, e.g. fading or discoloration of titanium or aluminum. For aluminum, the application/process solution only needs to be of pH >8 to cause visible surface changes. ■ 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 surfaces and could cause corrosion. ► Further detailed advice on hygienically safe and material-/value-preserving reprocessing can be found at www.ak-i.org, link to Publications, Red Brochure – Proper maintenance of instruments.
Preparations at the place of use ► If applicable, rinse non-visible surfaces preferably with deionized water, with a disposable syringe for example. ► Remove any visible surgical residues to the extent possible with a damp, lint-free cloth. ► Transport the dry product in a sealed waste container for cleaning and disinfection within 6 hours.
Preparation before cleaning ► Dismantle the product prior to cleaning, see Disassembling.
Cleaning/disinfection Product-specific safety notes on the reprocessing procedure
CAUTION
Damage to the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfectant agents in line with the manufacturer's instructions that are approved for stainless steel. ► Observe specifications regarding concentration, temperature and exposure time.
► Use suitable cleaning/disinfecting agents if the product is put away in a wet condition. To prevent foam forma-
tion and reduced effectiveness of the process chemicals: Prior to mechanical cleaning and disinfection, rinse the product thoroughly with running water.
Safe operation Note When the resection is performed at the exact angle and the implant is in place, the upper edge of the Plasmapore® coating lies flush with the resected part of the femur. ► Attach the Calcar cutting block to the final impacted rasp. Make certain that the cutting block is fully attached,
see Assembling.
