Device Description
The system consists of two major modules, the electrosurgical generator and the smoke
evacuation system. A single power switch controls both modules; the smoke evacuation system is
automatically controlled relative to footswitch or handswitch activation of the electrosurgical
generator.
Front Panel Indicators and Connectors
Connectors and indicators on the front panel are shown in Figures 1 through 3 and
subsequently described.
Smoke Evacuation System
1. Smoke Filter Connection. This connection, the large
circular structure on the face of the front panel,
accepts the external disposable filter pack which
provides first- and second-stage particulate
removal and odor adsorption. The circular ring retains the
Internal Filter, which is the third filtration stage
of the smoke evacuation module. Replacement
instructions for the internal filter are found in the
Annual
Maintenance section of this manual.
2. Vacuum Level Switch. This two-position rocker switch
controls the smoke evacuation system flow rate.
The left, or "normal", position ( ) runs the vacuum
motor at a level that is sufficient to draw the smoke
plume away from the surgical site during the LETZ
procedure.
The right, or "high", position ( ) of the switch runs
the vacuum motor at a higher speed, creating a flow rate
approximately 40% greater than the normal setting with the same tubing configuration. This
setting should be used whenever the distal smoke removal tube has a very small diameter, or
in any other circumstance where the smoke is not being completely removed.
The vacuum system does not have an activation switch of its own. It is automatically
activated by internal circuitry whenever the cut/blend or coag modes are activated, and
shuts off after a delay of five seconds from the time the electrosurgical generator
output is deactivated.
In addition to its convenience, this intermittent operation is
beneficial to the life of the filters and to the vacuum motor itself.
