Intended use
Clamping a saw blade Note Any Aesculap saw blade with a star coupling can be clamped in. ► Unscrew nut 13 from star coupling 16, using box wrench 12. ► Install saw blade 15 in straight position (of saw blade) 14 on star coupling 16. Alternatively, other saw blade
positions can be selected (see, for example, alternative saw blade position 17). ► Mount nut 13 and tighten it with box wrench 12. ► For cooling and irrigation:
– Push spray nozzle 18 onto handpiece 7. – Mount irrigation tube at 19. – Bend spray nozzle 18 towards the intended direction.
Sawing
The macro-Line sagittal saw handpiece GB125R is used to dissect bones in osteosynthesis procedures.
The optimum cutting performance is achieved by sawing with a high drive speed while moving handpiece 7 back and forth.
3.4
Note To avoid resonant oscillations of the saw blade, do not run the handpiece with a saw blade attached at maximum speed without load.
Operating principle
The macro-Line sagittal saw handpiece provides 1:1 conversion of the rotational movement of the motor unit to oscillating movement. The bone is dissected by the to-and-fro movement of the saw blade. Soft tissue parts touched by the saw blade remain largely unharmed.
4.
► Start the sawing procedure at a moderate speed, which is then slowly increased.

General safety instructions
Preparation
Non-compliance with the following instructions will preclude all responsibility and liability in this respect on the part of Aesculap. ► Before using the macro-Line sagittal saw handpiece and its accessories, visually check them to be sure they are not damaged. ► Use the macro-Line sagittal saw handpiece and its accessories only if they are in perfect condition.
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 the latest information on reprocessing and material compatibility see also the Aesculap extranet at www.extranet.bbraun.com The validated steam sterilization procedure was carried out in the Aesculap sterile container system.
6.2
General information
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.
6.3
Dismantling prior to carrying out the reprocessing procedure
► Disassemble the product immediately after use, as described in the respective instructions for use.
6.4
Preparations at the place of use
► 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.

Product-specific safety instructions for the reprocessing procedure Damage to, or destruction of the product caused by mechanical cleaning/disinfection! ► Only clean and disinfect the product manually. CAUTION
Packaging
► Always observe the instructions for use of packaging and storage devices. ► Place the product on a tray in such a way that it is protected against damage. ► Pack trays appropriately for the sterilization process (e.g. in Aesculap sterile containers). ► Ensure that the packaging will prevent a recontamination of the product.
6.10 Steam sterilization ► Prior to sterilization, remove any tools and adapters and uncouple the handpiece from the motor unit. ► 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
Damage to the product due to inappropriate cleaning/disinfecting agents! ► Only use cleaning/disinfecting agents approved for surface cleaning. Follow the manufacturer’s instructions for the respective cleaning/disinfecting agent. CAUTION 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 – be approved for plastic material and high-grade steel, – do not attack softeners (e.g. in silicone). ► Observe specifications regarding concentration, temperature and exposure time.
CAUTION
– Disassemble the instrument – Steam sterilization through fractionated vacuum process – Steam sterilizer according to DIN EN 285 and validated according to DIN EN ISO 17665 – Sterilization using fractionated vacuum process at 134 °C/holding time 5 min ► When sterilizing several instruments 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.
6.11 Storage ► Store sterile products in germ-proof packaging, protected from dust, in a dry, dark, temperature-controlled area.
