How the TissueSelect Feature Works
6-8 CUSA EXcel Ultrasonic Surgical Aspirator System Service Manual
TissueSelect 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:

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