Handpiece Descriptions
The information below pertains to the Turbo (D9920, D9924) shaver handpieces.
All these handpieces are equipped with sensors that automatically select the
proper speed range for the attached blade or bur. A maximum operating speed of
12,000 rpm in the forward and reverse direction and 4,000 cpm in oscillate for
shaver blades are attainable.
The 2-Button Shaver Handpiece (D9924) is also equipped with a
DIRECTION SELECT button to change between forward, reverse, and
oscillate, and an ON/OFF button to control the handpiece from within the
sterile field. Window indexing and handpiece operating speed control can
be controlled from within the sterile field, as explained below.
1. Blade Locking Collet - To insert a blade or bur, align the key on the
blade hub with one of the slots in the collet. Completely push the hub
into the collet to lock it into place. Pull on the blade to ensure it is
locked. To remove the blade, rotate and hold the collet in the “UNLOCK”
direction and remove the blade.
2. Suction Port Valve - Manually controls suction flow. Move towards the front of
the handpiece to open, or increase flow. Move towards the back of the handpiece
to restrict or stop flow. To attain maximum performance while resecting tissue
or bone, the suction port valve must be in the fully open position.
3. Suction Port - Connects to the suction line for aspiration.
4. DIRECTION SELECT Button - Press and release to select the direction
of blade rotation between forward, reverse and oscillate.
Controlling speed using the buttons on the D9924: The following
