Intended use
The S4Cervical Spinal System torque wrenches with click function are used to tighten the S4Cervical System set
screws with a defined torque:
■2.8 Nm for tightening the set screw in the screw head/hook head/occipital plate/transverse connector and other
connectors.
Safe handling and preparation
CAUTION
Federal law restricts this device to sale by, or on order of a physician!
►Ensure that the product and its accessories are operated and used only by persons with the requisite training,
knowledge, or experience.
►Read, follow, and keep the instructions for use.
►Use the product only in accordance with its intended use, see Intended use.
►Remove the transport packaging and clean the new product, either manually or mechanically, prior to its initial
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.
Safe operation
►Make sure that the instrument is correctly mounted and that the hexagonal bit is firmly fixed.
►Tighten the set screws, turning the torque wrench evenly in a clockwise direction. In doing so, make sure that
the torque wrench is turned without jerking.
►Instrument will click when the defined torque is obtained.
Disassembling
►Unscrew the thumb nut 1from the rear of the wrench head, see Fig. A.
►Remove the hexagonal bit 3from the inner surface of the wrench head, see Fig. B.
►Take care not to lose the hexagonal bit and the thumb screw.
Assembling
►After cleaning, reassemble the hexagonal bit 3in the torque wrench by inserting it into the bit cavity on the
inner surface of the torque wrench head, see Fig. A.
The inner surface of the torque wrench can be identified by the two integrated screws 4.
►Engage the thumb nut 1on the rear of the wrench head and securely tighten, see Fig. B
The rear of the wrench can be identified by the smooth surface 2.
Validated reprocessing procedure
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 oper-
ator/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
https://extranet.bbraun.com
The validated steam sterilization procedure was carried out in the Aesculap sterile container system.
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 temper-
atures >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. Fail-
ure 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 applica-
tion/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.a-
k-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.
Preparations at the place of use
►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.
Preparation before cleaning
►Disassemble the product prior to cleaning, see Disassembling.
Cleaning/disinfection
Product-specific safety notes on the reprocessing procedure
►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/disinfecting.
– as a pre-cleaning procedure for products with encrusted residues, in preparation for mechanical cleaning/dis-
infecting.
– as an integrated mechanical support measure for mechanical cleaning/disinfecting.
– for additional cleaning of products with residues left after mechanical cleaning/disinfecting.

WARNING
Risk of injury/correction loss due to improper mounting of the set screw!
►Set the set screw in place correctly.
►Make certain that the rods are correctly positioned in the body of the polyaxial
►When tightening the set screw always apply counter torque using the coun-
tering instrument intended for this purpose.
WARNING
Risk of injury due to improper mounting of the transverse connector!
►When tightening the set screw make sure that the transverse connector is
completely seated on the rods.
►Fully tighten the set screw on the transverse connector using the torque
wrench.
CAUTION
Risk of damage to the implant by applying excess torque to the set screw!
►Slowly tighten the set screw using the torque wrench, until the torque wrench
clicks.
CAUTION
Risk of damage to the torque wrench due to improper usage!
►To undo a tightened set screw always use the set screw removal screwdriver
FW064R.
CAUTION
Damage to the countering instrument due to improper usage!
►Always slide the countering instrument over the rod receptacle head as far as
it will go. In doing so, make sure that the implant entirely engages into the
slot at the working tip.
►Make sure that the rod protrudes on both sides of the countering instrument.
CAUTION
Wrong assembly leads to malfunction of the instrument!
►Make sure that the instrument is assembled correctly.
SN
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 instruc-
tions which
–are approved for (e.g. aluminum, plastics, 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 washing temperature of 55 °C.
