WARNING
the trial implant by means of
the midline marking and on the
AP-view X-ray image.
Ensure that the position of the
trial implant does not change
during reaming.
Risk of injury to nerves and spinal
cord caused by too deep insertion
of the reamer!
Only use activC instruments.
WARNING
Use the instruments according
to their intended use.
For reaming the holes, apply the
reamer only in combination with
a correctly
positioned trial implant and
with the reamer guide coupled.
Ensure that the depth stop of
the trial implant abuts to the
anterior edge of the vertebral
body.
Always maintain lateral X-ray
control while reaming the holes.
To ream the first hole under lateral X-ray control:
With the motor running, push reamer handpiece 6
at an even speed and with slight forward pressure
into the first guiding slot down to the stop.
Pull back reamer handpiece 6 and, after moving
the pins of mounting block 4 to the second guiding
slot, repeat the reaming procedure under lateral X-
ray control.
The reaming depth will be limited by the stop at
reamer guide 3.
With the hand control inactivated, shift the safety
stop on the pneumatic motor to position "0".
Cautiously pull out reamer handpiece 6 first from
the rear and then from the frontal reamer guide 3.
Remove the reamer guide 3 and trial implant from
the intervertebral disk space. Clean the fin bed with
nerve hooks from the discectomy set.
