Intra-Operative Instructions
1. Set the aiming beam to high intensity.
2. Test the integrity of the aiming beam.
Hold a non-reflective surface, such as a tongue depressor, in front of
the optical fiber tip. For side-emission delivery systems, hold the non-
reflective surface in front of the side opening at the fiber tip.
A green spot, the aiming beam, should appear on the surface. If the
aiming beam is weak, check that it is set to high intensity. If the aiming
beam is still weak, verify that the laser debris shield and optical fiber’s
connector are not damaged. Refer to Inspect the Debris Shield and the
section in the appropriate optical fiber instruction guide (look under
“Inspect the laser connector”).
WARNING:
• Do not use the optical fiber if the aiming beam is set to high intensity
and is still weak or not visible; the optical fiber may be damaged. A
damaged optical fiber may cause accidental laser exposure or injury to
the treatment room personnel or patient, and/or fire in the treatment
room.
• Do not use the laser system or optical fiber if the aiming beam has not
been verified. Verifying the aiming beam integrity is extremely
important for the safe operation of your laser equipment.
• Do not use the laser system or optical fiber if the aiming beam is not
visible. Operating the laser system without the aiming beam may
result in laser exposure to non-target tissue and possible injury.
NOTE:
When using the optical fiber with an endoscopic camera, lower the
intensity of the camera light if the aiming beam is weak or not visible.
Doing so will not affect visibility at the treatment site, since the camera
compensates for the lower level of light.
3. Enter the desired parameters into the Energy, Frequency and Pulse
Width selectors on the control panel.
4. Position the aiming beam on the target tissue.
