Warning:
Release the footswitch prior to lifting handpiece from the treatment area. Failure to do this
may result in burns or injury to the patient due to inadvertent laser exposure.
2.9 Handpiece Tracking (IOTS – Intelligent Optical
Tracking® System)
The handpiece is capable of sensing hand motion velocity during treatment, and maps
velocity feedback to ensure uniform delivery of the treatment beam. The IOTS is configured
to work in much the same way as a computer mouse does, in that it senses motion when
moved in a plane.
The IOTS senses velocity, i.e. not only the speed of the handpiece motion but also the
direction. This allows treatment to be bidirectional. The handpiece may be stopped after
one pass and the direction of motion reversed without loss of function. Simulate Mode
allows the operator to practice this hand motion and listen to the tones generated by the
machine without firing the laser.
NOTE:
In order for the IOTS to stay locked during a treatment, it is important that the tip
stay in good physical contact and approximately perpendicular to the skin.
NOTE:
There is a specific cadence preferred by physicians skilled in the use of the Fraxel
Laser systems. After selection of the desired treatment wavelength, the sequence is:
1. Place the laser in Treat mode.
2. Place the handpiece on the area to be treated.
3. Press the footswitch down.
4. Move the handpiece, performing as many passes as are required to complete treatment
of the selected area.
5. Release the footswitch. Lift the handpiece and move it to the next area to be treated.
6. Restart the sequence at step 3.
7. When finished, release the footswitch, remove the handpiece from the skin, clean and
store carefully.
Warning:
Do not lift the handpiece from treatment area with the footswitch depressed during
treatment. Release footswitch prior to lifting handpiece from treatment area. Failure to
follow these guidelines may increase the risk of injury to the patient.
