Two styles of ratcheting handles are provided within the set.
The handles can be switched between Forward (F) – Locked (
) – Reverse (R) positions by rotating the collar of the handle.
To couple a tap to the handle, depress the button on the
handle and insert the tap until the tap bottoms out. Release
the button and verify that the tap is retained by gently
pulling on it.
Place the ratchet in either Forward or Locked position. Apply
the instrument to the entry point of the cannulation and tap
to the desired depth.
For each tap, the thread length is 30mm. Additional
markings are provided in 10mm increments to assess
tapped depth.
Once the pedicle has been tapped to the desired depth,
switch the ratchet to Reverse (R) or the locked position and
turn the handle counter-clockwise to remove the tap.
Use a ball tip feeler to verify cannulation wall integrity and
assess hole depth.
Remove the tap from the handle by depressing the button
and then removing the tap.

Head Adjuster
Choose desired screw length and diameter. To improve
surgical flow and minimize non-operative time, two poly
drivers have been included in the set to enable concurrent
screw loading and screw placement.
POLY DRIVER ASSEMBLY
Insert the Poly Driver Shaft into the Poly Driver Handle and
advance until the handle engages the Driver Shaft.
If desired, assemble the optional Poly Driver Sleeve to the
Poly Driver Handle by depressing the release lever buttons
and sliding the sleeve towards the handle. The sleeve
allows the instrument to be held distally, improving
stability. Additionally, the sleeve reduces the potential that
soft tissue will become entangled around the driver during
screw insertion.
