Product description
3.1
Components required for operation
When putting the sagittal saw into operation, the following components are required: ■ Motor unit (e.g. pneumatic motor GA552, battery mini pistol GA647) ■ Saw blade (e.g. GC128R, GC138R, GC148R)
3.2
Intended use
The sagittal saw GB390R is used for severing bones in small-bone surgery (e.g. hand and foot surgery).
3.3
Operating principle
The saw attachment converts the rotational movement of the motor drive into saw blade oscillations in a 1:1 ratio. The bone is severed by the saw blade oscillations. The minimal oscillation angle of the saw blade protects the surrounding soft tissues. The sagittal saw can be mounted on the motor drive in eight different positions (8 x 45°).
4.
Preparation
Non-compliance with the following instructions will preclude all responsibility and liability in this respect on the part of Aesculap. ► Before using the sagittal saw and its accessories, check to be sure that neither are damaged. ► Use the sagittal saw, motor drive and accessories only if they are in perfect working order.
5.

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
► Remove the saw blade and motor drive from the sagittal saw.
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.
6.5
Drinking water Fully desalinated water (demineralized, low microbiological contamination: drinking water quality at least) Room temperature
Preparation before cleaning
► Prior to first mechanical cleaning/disinfection process: Eccos holder GB673R must be assembled in a suitable tray
(e.g. JF214R). ► Carry out non-fixating/NaCl-free pre-cleaning immediately after use.
Phase I ► Clean the product under running faucet water, using a suitable cleaning brush until all visible residues have been removed from the surfaces. ► Mobilize non-rigid components, such as set screws, links, etc. during cleaning. Phase II ► Dry the product in the drying phase with suitable equipment (e.g. cloth, compressed air), see Validated cleaning and disinfection procedure. Phase III ► Wipe all surfaces of the product with a single-use disinfectant wipe. Phase IV ► After the specified exposure time (at least 1 min), rinse the disinfected surfaces under running FD water. ► Drain any remaining water fully.
