General safety instructions

Note Adhere to national statutory regulations, national and international standards and directives, and local, clinical hygiene instructions for sterile processing. 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 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. Note If there is no final sterilization, then a virucidal disinfectant must be used. Note For up-to-date information about reprocessing and material compatibility, see B. Braun eIFU at eifu.bbraun.com The validated steam sterilization procedure was carried out in the Aesculap sterile container system.

3.2

General information

The KERRISON bone punches are used for removing bone, ligaments, cartilage and similar tissue (neurosurgery, orthopedics and traumatology).

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 "AKI-Brochures", "Red brochure".

Cleaning/Disinfection

3.7.1

Product-specific safety information on the reprocessing method

Damage to or destruction of the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable disinfection temperature of 95 °C. ► With PVD coated products, do not use oxidizing process chemicals (e.g. H2O2), as these can cause bleaching or

layer loss. ► Use suitable cleaning/disinfecting agents if the product is disposed of in a wet condition. To prevent foaming and

degradation of the efficacy of the process chemicals: prior to mechanical cleaning and disinfection, rinse the product thoroughly with running water
