Portability of the Sapphire
®
Portable Diode Laser:
The Sapphire Portable Diode Laser does not need to be attached to the wall outlet to function. A rechargeable
lithium-ion battery powers the Sapphire Portable Diode Laser. When fully charged, the Sapphire Portable Diode
Laser can be operated for up to 40 minutes, for most procedures, before needing to be recharged. So, the
Sapphire Portable Diode Laser can be taken from operatory to operatory as needed. (Be certain that all safety
considerations are followed wherever the Laser is operated, including protective glasses for operator, assistants,
and patients as well as signs warning others that laser procedures are taking place.)
Battery Power Level Indicator:
If the battery charge drops below 3.4v, the Battery Power Indicator will change from green to amber. This is
usually not cause for concern unless the unit is intended to be used for an especially extended procedure
(greater than 40 minutes), particularly if the procedure requires for the laser to be operated in the continuous
wave mode at outputs greater than 2.0W. If the battery is discharged below 2.5v, the Battery Power Level
Indicator changes from amber to red. This indicates that very limited power remains and that the Laser should be
reconnected to the Power Converter and recharged before using. If the battery continues to discharge, “E 4” will
appear in the Laser Power display window and the READY LED will fl ash red, indicating that there is not enough
power to initiate lasing. The unit will need to be plugged into the wall outlet and allowed to recharge before it can
be used.
Error Codes:
E 1 – Output power Not in Calibration: Exceeds ± 20% of indicated output
E 2 – Over temp; Diode base temperature >50 °C
E 3 – Low battery; Recharge or replace battery (Battery indicator RED)
E 4 – No power; No output or drive current (READY LED blinks RED, too)
E 5 – Handpiece communication error
8. SAPPHIRE PORTABLE DIODE LASER OPERATION AND USE
Operating Modes:
The Sapphire Portable Diode Laser will deliver energy in either continuous wave (CW) or Pulsed (P), “temporal
emission mode” (time related mode). Selection of the appropriate mode will allow the operator to optimize control
of target tissue temperatures and the effi ciency of energy delivered. The pulse duration (0.05 seconds) and the
number of pulses per second (10) have been fi xed by the manufacturer. Therefore, the operator will need to
adjust only the laser power and mode.
Continuous Wave (CW) Mode :
The CW mode is generally the fastest way to ablate tissues but heat can build up and cause collateral damage
to adjacent tissues. Cool the tissues being treated by using periodic blasts of air from a triplex syringe and high
speed suction. You may also use water to cool in areas where there is prolonged exposure to the Sapphire
Portable Diode Laser beam. Avoid using the air syringe when you have an opening in soft tissue adjacent to
or within the surgery site, as an air embolism may occur resulting from air captured within the tissue during the
cooling process.
