Note
The reaming of the fin bed determines the position and
orientation of the disk prosthesis in the plane of the
intervertebral disk.
¾To ream the first hole under lateral X-ray control:
With the motor running, push reamer handpiece 6
at an even speed and with mild forward pressure
into the first guiding slot down to the stop.
¾Pull back reamer handpiece 6and, after moving
the pins of mounting block 4to the second guiding
slot, repeat the reaming procedure.
The reaming depth will be limited by the stop at
reamer guide 3.
¾With the hand control not actuated, shift the
safety stop at the pneumatic motor to position "0".
¾Cautiously pull out reamer handpiece 6first from
the rear and then from the frontal reamer guide 3.
¾Remove reamer guide 3and the trial implant from
the vertebral disk space.
¾Clean the fin bed with nerve hooks from the
discectomy set.
Disassembling
Uncoupling the reamer guide/handle from the trial
implant
¾Turn locking pipes 8of reamer guide 3or handle 2,
respectively, to position "open" .
¾Pull off the trial implant in axial direction.
¾Decouple reamer 5from reamer handpiece 6as
described in instructions for use TA011267.
Detaching the mounting block from the reamer
handpiece
¾Hold locking clip 9of mounting block 4pressed
down (arrow marking points to position "open" )
and pull off the mounting block from reamer
handpiece 6.
WARNING
Mispositioning of the intervertebral
disk prosthesis due to failure to
observe the midline!
¾Check the central position of
the trial implant by means of
the midline marking and on the
AP-view X-ray image.
¾Make certain that the position
of the trial implant does not
change during reaming.
WARNING
Risk of injury to nerves and spinal
cord caused by too deep insertion
of the reamer!
¾Only use activ C instruments.
¾Use the instruments according
to their intended use.
¾For reaming the holes, apply the
reamer only in combination with
a correctly selected and
positioned trial implant and
with the reamer guide coupled.
¾Take care that the depth stop of
the trial implant abuts the
anterior edge of the vertebral
body.
¾Always maintain lateral X-ray
control while reaming the holes.
