Function checks
Note The following function checks must be carried out prior to every surgical application of the product!
Check that the tool is firmly seated ► Hold the small oscillating saw with one hand. ► Hold the back of the tool with the thumb and index finger of the other hand. ► Check that the tool is firmly seated by pulling on the tool. When doing so, ensure that no relative motion occurs
between the saw blade and chuck adapter.
The saw oscillates backwards and forwards.
3.3
Intended use
The small oscillating saw is used to dissect bone in osteosynthesis procedures and small bone surgery (hand and foot surgery, craniofacial and maxillofacial surgery, plastic surgery, spinal surgery). The connector (4-6) is in accordance with DIN 13940.
► Switch on the pump and activate the foot control switch until irrigation solution is sprayed out of the nozzle 12. ► Check for proper and reliable functioning. ► If unusual noises occur or the handpiece heats up a lot, do not use the handpiece any more.
Cooling/irrigation The spray nozzle is used for cooling and clearing the operating field with a sterile irrigation solution. This reduces the risk of necrosis and enables the surgeon to work more precisely, more quickly and more gently on the tissue.
3.4
Operating principle
WARNING
5.3
Safe operation
The bone is dissected by the to-and-fro movement of the saw blade at an oscillating angle of 10.4°. Any soft tissue parts touched by the saw blade remain unharmed. Cooling/irrigation The sterile irrigation solution is sprayed through the spray nozzle 10 into the operating field. This cools down the bone, tissue and tool and washes away the saw chippings, preventing the tool in direct contact with the bone from getting too hot.
Risk of burns to soft tissue due to heated handpiece as a result of defective bearings! ► Make certain that there is no visible abrasion or similar at the site where the chuck adapter leaves the housing. ► Do not use the handpiece any more or have it repaired.
Risk of burns to patient and user due to hot motor/hot tool! ► Put down the motor/hot tool beyond reach of the patient. ► Use a cloth to protect against burns when changing the motor or tool. WARNING
Risk of injury and/or malfunction! ► Always carry out a function check prior to using the product. WARNING Injuries to tissue if the tool is unintentionally released or moved! ► Make certain that the tool is correctly tightened in the chuck adapter with the straining screw and that the tool is seated tightly. WARNING Risk of injury when using the product beyond the field of view! ► Apply the product only under visual control. WARNING
WARNING
WARNING
Risk of injury and material damage due to inappropriate use of handpieces or motors! ► Always follow the safety advice and information given in the instructions for use of the handpieces and motors. ► Do not exceed the specified maximum motor speed. Impaired healing process! ► Use the saw blade with the smallest possible cutting width to – complete the saw incision in the shortest possible time. – This facilitates the healing process due to low bone loss and low thermal stress of the bone and tissue. Risk of injury from a broken saw blade! ► Do not twist, cant or bend the saw blade.
WARNING Risk of injury from cracks and cuts in high-speed saws with sharp edges! ► Hold the saw tightly in the hand. WARNING Risk of burns from a hot tool! A blunt tool can cause heat to develop quickly. ► Use only sharp tools in new condition. WARNING Risk of infection and contamination from unsterile parts! ► Use only sterile/sterilized parts in the sterile area. WARNING Risk of infection and contamination due to aerosol formation! ► Take appropriate protective measures, e.g., watertight protective clothing, face mask, protective goggles, and a suction extraction system.

Validated reprocessing procedure
6.1
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 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
6.3
CAUTION
Note The saw achieves the best cutting performance at a high speed.
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.
6.5
► Hold the saw tightly in the hand. ► Activate the foot control switch for the motor unit and if applicable the foot control switch for the pump. ► Begin at a low speed. ► Once the saw blade is inserted in the bone gap, continue at a higher speed.
Dismantling prior to carrying out the reprocessing procedure
► Disassemble the product immediately after use, as described in the respective instructions for use.
6.4 Damage to the motor unit due to incorrect coupling of the saw! ► Couple the saw with the motor unit only while the motor is inactive.
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.
Preparation before cleaning
► Remove the tool, see Changing the tool during an operation. ► This product should be disassembled for cleaning ► Prior to the first mechanical cleaning/disinfection process, mount the Eccos holder GB682R in a suitable tray (e.g.
JF214R). ► Carry out non-fixating/NaCl-free pre-cleaning immediately after use.
6.6
Cleaning/disinfection
► Move the saw forwards in the bone using mild pressure and slow, wave-like movements. When doing so, make
certain that no jerky movements are made. ► Ensure the tool only applies mild pressure on the bone. ► Do not cant the tool so that the saw blade does not break. (This does not make sense, but cannot decifer what
Product-specific safety instructions for the reprocessing procedure
is trying to be said) ► Make sure there are no resonances in the saw blade when idle. ► If resonances do occur, continue working at a different speed.
Changing the tool during an operation Risk of injury from the tool due to accidental activation of the motor! ► Change tools only with the motor unit uncoupled. WARNING Disconnect the saw from the motor unit ► Switch off the motor unit. ► Press release 5. ► Remove the saw. Tool change ► Undo straining screw 3 on the chuck adapter 8 using the hexagon socket screw key 1. ► Remove the tool. ► Insert the new tool into the adapter as far as it will go. ► Turn the tool with triangular shaft 9 in the chuck adapter 8 slowly, applying pressure. You will feel the tool click into position. ► Tighten straining screw 3 on the chuck adapter 8 using the hexagon socket screw key 1.
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 – are approved for plastic material and high-grade steel, – do not attack softeners (e.g. in silicone). ► Observe specifications regarding concentration, temperature and exposure time. ► Do not exceed the maximum allowable temperature of 60 °C.
► Dry the product for at least 10 minutes at a maximum of 120 °C.
Note The indicated drying temperature is a guide temperature only. It must be checked taking into account the specific conditions (e.g. load) and if applicable adjusted. ► Do not clean motors/handpieces by ultrasonic treatment and do not immerse them in any liquids. To avoid the
risk of corrosion/malfunctioning, allow any fluid that has entered the product to drain out immediately.
