CE Instruction for use and maintenance (Summary)
This is done in the usual fashion by autoclaving. All instruments, which are supplied non-sterile, are packaged individually in shipping/storage boxes or plastic bags.
To clean them prior to their first use or after surgery, we recommend a neutral PH (or slightly alkaline detergent according to the recommendations of the detergent manufacturer. Put the washing cup on for washing. All instruments should then be thoroughly rinsed and dried prior to steam sterilization.
The washing cup must be removed before sterilization.
We recommend autoclaving according to standard hospital sterilization procedures and
within the guidelines of the autoclave manufacturer, to assume a Sterility Assurance Level (SAL) is:
Pre Vacuum and hold at 270 F for at least 4 minutes.

Clean Compressed air or Nitrogen
The Woodpecker must be operated at a pressure of 7-8 bar (100-120 PSI).
The compressed air must be free of particles.
The Woodpecker is operated with a twin-hose (inner-hose 18 mm and air outlet hose)
Bent hoses may prevent the unit from operating satisfactorily.
IMT AG recommends servicing the Woodpecker at least once per year.
The oscillating, axial forward and backward movements of the Woodpecker permit
gentle, well-fitting modelling work in the bone marrow area.
The bone chips removed by the forward movement of the rasp are loosened towards
the rear and neutralized. In this way, the rasp is prevented from wedging or jamming in
the cortical bone.
Fissures which are caused by excessive radial forces can be avoided.
Always start with the smallest rasp.
The rasps must not be inserted in one process. Pressure must be exerted for forward
rasping; pull when rasping backwards.
To obtain a precise, cortical prosthesis seating over a large surface, it is sufficient to
continue rasping until the machine can not distally insert the rasp any further, due to
resistance from the cortical bone.
Additional, forceful insertion of the final rasp, using a hammer or other instruments, is
not recommended. This could cause axial pressure, unphysiological stretching of the elastic femur
bone, damage to the bone cortex and fissures.
Even, machine rasping results in a clear improvement in the quality of the prosthesis
seating and the primary fixing of the prosthesis.
