Date of manufacture

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.

Disassembling the product before carrying out the reprocessing procedure ► Disassemble the product immediately after use, as described in the respective instructions for use.

Intended use

Preparations at the place of use

The tibia cutting height gauge is used in operations on the knee joint. It can be used to adjust the height of the saw cut.

► 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.

Safe handling and preparation

WARNING

Risk of injury caused by incorrect operation of the product! ► Attend appropriate product training before using the product. ► For information about product training, please contact your national B. Braun/Aesculap agency.

Preparation before cleaning ► Dismantle the product prior to cleaning, see Disassembling.

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.

CAUTION

Safe operation

Damage to the product due to inappropriate cleaning/disinfecting agents and/or excessive temperatures! ► Use cleaning and disinfecting agents according to the manufacturer’s instructions which – are approved for use e.g. on aluminum, plastic materials and stainless steel, – do not attack softeners (e.g. in silicone). ► Observe specifications regarding concentration, temperature and exposure time.

Attaching the tibia cutting height gauge to the cutting template ► Loosen fixing bolt 1 on the fixation support, see Fig. A. ► Insert instrument into the intended opening of the cutting template. ► Tighten fixing bolt 1 on the fixation support until feel a noticeable resistance with your hand.

► 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. ► Carry out ultrasound cleaning:

– as an effective mechanical supplement to manual cleaning/disinfection. – as a pre-cleaning procedure for products with encrusted residues, in preparation for mechanical cleaning/disinfection. – as an integrated mechanical support measure for mechanical cleaning/disinfection. – for additional cleaning of products with residues left after mechanical cleaning/disinfection.

Adjusting the cutting height ► Move cursor 2 on the fixation support 3 into the desired position, see Fig. A.

The cursor slides by increment of 2 mm. The numerical values indicate the cutting height to be sawn.

Disassembling ► Pull out fixation support 3 from the cursor 2. ► Unscrew fixing bolt 1 of the fixation support until feel a noticeable resistance with your hand.

Note Fixing bolt 1 and cursor 2 is not removable.

Validated reprocessing procedure Manual cleaning/disinfection 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. The recommended chemistry was used for validation. 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 also the Aesculap Extranet at https://extranet.bbraun.com The validated steam sterilization procedure was carried out in the Aesculap sterile container system.

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.
