OPERATION
Set Up and Operation
The E2 MicroProbe¥ system must be set up and operated with care. The
endoscopic laser probe is a fragile component and great care should be used
when handling it.
Training on the safe operation of the system should be provided at the time of
installation. This includes complete in-service training. This training session is
usually conducted in one day. From time to time it may become necessary to provide
retraining. This can be provided by contacting your sales representative.
Endoscopes and Probes
Before each use, the endoscope or probe should be thoroughly inspected in
order to detect any irregularity or abnormality. If these are noted, the
endoscope or probe should not to be used and a new one should be employed.
Inspection of the Optical System
The endoscope allows two functions. The first is optical viewing and the second
is delivery of therapeutic laser energy. Both of these functions can be
determined prior to insertion into the eye. It is essential that the viability of the
fiberoptic pathways be demonstrated prior to use and this may be done in a
rather simple manner.
To check the integrity of the optical viewing system, direct the distal end of the
endoscope to a point of reference, such as the focus ring at the video adapter for
the image fiberguide on the Front Panel of the E2 MicroProbe¥. A clear view
should be obtained.
The aiming beam provides a good method of checking delivery of the therapeutic
laser energy since it passes down the same delivery system as the therapeutic
laser beam. If the aiming beam spot is not present at the distal end of the
delivery system, its intensity is reduced or it looks diffused, this is a possible
indication of a damaged or not properly working delivery system.
