Tissue Select Feature
Tissue Select Settings
2-10
Ultrasonic energy is inherently selective. It fragments soft tissue more
easily than collagen-rich tissue. The Tissue Select feature is a safety
setting unique to the CUSA systems that allows the surgeon to increase
selectivity and safety without sacrificing procedure speed. The Tissue
Select feature limits power when the tip encounters a blood vessel,
providing a wider margin of safety in preserving the vessel.
Tissue Select has 5 settings:
Level of Selectivity
0 Off (Default)
1 Low
2 Medium
3 High
4 Maximum
Standard Operation
Power is continuous. The console provides ample adaptive power, as
necessary to maintain amplitude under heavy load.
Tissue Select High or Maximum Setting Operation
Both adaptive power and amplitude are reduced.
• When the tip encounters strong tissue, it will not be fragmented at all
due to reduction in amplitude.
