3.3.3. Procedure Settings
In the Operate Screen, select the laser settings appropriate
for the procedure. Please refer to Section 3.2.8 for setting
values appropriate for a variety of common soft-tissue
procedures. Once all of the desired settings are established,
press the Ready button to place the laser system in Ready
Status.
3.3.4. Activate the Working Beam
Once the system is in Ready Status, you are ready to activate
the working beam. Ensure that all persons in the operatory
are wearing eye protection. Position the handpiece tip over
the intended site, and then step on the foot pedal to activate
the working beam. The Display will show a Laser Emissions
Occurring screen and the front of the Base will show a red
indicator light. The light will be continuously on when in
Continuous mode, and will rapidly blink when in Pulse
mode. The Base will also emit a repeating audible signal
to let you know the laser beam is active, without having to
look away from the treatment to confirm the laser status.
While the working beam is active, move the tip over the
desired site using even, painting type strokes, going back
and forth along the target tissue until the desired effect is
achieved. Avoid leaving the tip over one location for an
extended period as this may causing burning and charring
of the tissue. During an extensive procedure, the tip may
become fouled with debris and the laser emissions may
become blocked. If you notice this is occurring, discontinue
the working beam and place the unit in Standby Status.
Remove the existing tip and attach a new tip, then proceed
with the procedure.
For surgical procedures, pass the fiber along the treatment
site with a steady paintbrush type stroke. It may be necessary
to repeat the motion over the site to achieve the desired
depth and/or results. For temporary pain relief sweep the
handpiece over the treatment area in a steady circular
motion for 5 minutes. Effective results are often achieved
through brief, but repeat office visits over several days.
For whitening, position the handpiece over the teeth and
expose for 5 minutes. Continuously monitor the status of the
whitening formula to ensure the teeth remained covered by
the formula. Apply suction as needed to pick up whitener
that may separate from the teeth.
CAUTION: Visible and invisible laser radiation
will be emitted from the handpiece tip. Make
sure these instructions are followed exactly and
all precautions and preparations are in place to
avoid unintended exposure to laser radiation.
CAUTION: For tooth whitening procedures,
do not expose the whitening gel for more than
5 minutes. Excessive tooth temperatures may
occur.
CAUTION: Use of controls or adjustments or
performance of procedures other than those
specified herein may result in hazardous
radiation exposure.
CAUTION: Applying excessive force to the
fiber tip while the laser energy is emitting could
create a situation of fiber fragments. When
contacting tissue or other material, the debris
adheres to the fiber and absorbs the laser
energy, generating an intense amount of heat.
This heat could cause the glass fiber to crack or
fragment. Always remove any fragments from
the fiber and/or work area.
3.4. Daily Shutdown
Once you have concluded the procedure, ensure that the
system is in Standby Status. On the Display Module, press
the Lock key. Alternatively, press the ‘Home’ button of the
iPod touch to close the Precise SHP App. Press and hold
the power button on the Base Module for 3 seconds to turn
the Base Module off. Detach the tip and dispose of it in the
appropriate contaminated sharps container. Remove the
handpiece sleeve from the fiber cable, attach the handpiece
tip cap and clean the sleeve and cable as indicated in
Section 4.1. The handpiece is magnetic, and magnets
within the top of the Base Module and in the Display Stand
help to hold the handpiece in place when it is stored in
these locations.
CAUTION: Tips are single-use only and are to
be disposed of after each patient.
CAUTION: Failure to use the tip cap could
permit dust and debris to collect on the optical
interface and permanently damage the
handpiece optics.
3.5. Emergency Shutdown
If for any reason there is a need to terminate laser
emissions quickly, numerous means are provided to do so:
• Release the foot pedal – releasing the foot pedal will
deactivate the working beam. NOTE: The aiming beam
will still be active.
• Laser Stop Button – Both the display and base module
feature a laser stop button. These switches are redundant
to each other. Pressing the Laser Stop on either the
