Valleylab CUSA EXcel-8 - Benefits of TISSUE Select

How the TISSUE Select Feature Works
TISSUE Select Operation
Power is interrupted. The ultrasonic generator provides less reserve
power to the handpiece:
* The tip still fragments “softer” tissue easily.
* But, when it encounters “stronger” tissue, the power the tip receives is
no longer enough to fragment the tissue. The tip stalls.
At increased selectivity settings (+ to ++++), suction and the tip cross-
sectional area remain the same, and stroke amplitude and tip acceleration
decrease slightly:

Fragmentation performance vs.
TISSUE Select settings Setting Fragmentation Rate
Std and + maximum
++ and +++ slightly decreased rate, increased tissue
selectivity and tactile feedback
++++ slowest rate, maximum selectivity and
tactile feedback
Benefits of TISSUE Select
The TISSUE Select feature presents several benefits:
* Maintains fragmentation ability.
* Reduces (automatically) fragmentation rate.
ο Provides maximum tissue selectivity.
* Gives surgeon superior tactile feedback.
* Gives surgeon greater control and precision when dissecting near
delicate structures.
