• A direct, reflected or scattered laser beam can cause permanent blindness. All individuals in the laser
use area must wear laser safety glasses. Other parts of the body should also be protected. The laser
beam can cause serious injury to the skin and eyes.
•
Even if you are wearing safety glasses, never look directly into the aperture where the laser comes out;
you could be blinded by the laser. Both the main laser and the guide light are dangerous. The
safety glasses provided only temporary protection.
•
Take great care to avoid overheating in the vicinity of critical tissues such as nerves and blood vessels.
• A pulse speed of 20 or 25 pps will tend to heat up the target area more than one of 10 pps or less.
Keep this in mind to set the power and adjust the flow of the spray.
• Keep combustible tubes, gases and other materials well away from the laser beam. Never irradiate
combustible materials such as trachea tubes, non-woven cloth, and surgical gloves with a laser beam.
These could suddenly ignite. Also watch out for combustible medical solutions and gases inside the
patient’s body.
• Do not inhale laser plume produced by the laser irradiating the treatment area or get them in your
eyes. Because the laser plume may contain infectious viral particles and bacteria. Use high-speed
suction to remove all smoke and particulates in the laser plume. Also use clinical masks for protection.
•
Do not use this instrument in the presence of a combustible anesthetic or an elevated concentration of
oxygen; this could result in ignition or explosion. A laser beam will readily ignite a tracheal tube
such as those made of silicon rubber in the presence of a high concentration of oxygen or an
anesthetic gas mixed with oxygen. For example, a laser beam will instantly ignite the tube if the
oxygen concentration is 48%.
•
If use of oxygen is absolutely essential, the oxygen delivery tube must be protected with a
non-combustible cuff and steps must be taken to insure that there is no leakage of oxygen.
•
The output depends somewhat on the diameter of the contact tip; a larger diameter will deliver more
energy. Keep this in mind to make irradiation settings.
•
This equipment must not be used for any purpose other than vaporization, coagulation, hemostasis and
resection of biological tissues. Never direct the laser beam to anything except the treatment area.
•
Handle contact tips with great care; they break easily. A piece of a broken tip could cut the patient
and cause bleeding or might be left in the tissue being treated. Never bend or apply force to the tip.
Thin tips are especially delicate and will break very easily if some force is applied to the part coming
out of the pipe. Use a rubber dam if there is a chance that the tip might get broken during treatment.
• Before emitting a laser beam, check the aim with the guide light or by touching the target with the tip.
• Never shine the laser beam on prosthetic devices, mirrors or anything that will reflect it or scatter it.
Cover the treatment area with damp gauze or find some other way to avoid the risk of reflected laser
light.
•
Always leave the unit in Stand-by mode when it is not required to actually emit a laser beam.
