Bipolar Operation
Two modes are available:
•
Bipolar – for most applications. The system provides low voltage to prevent
sparking. The power remains constant over a specific range of tissue
impedance, allowing a consistent tissue effect.
•
Macrobipolar – for bipolar cutting or rapid coagulation. The system provides
higher voltage and greater power than with the bipolar mode.
Instant Response Technology
The LigaSure generator automatically senses tissue impedance and adjusts the
output to maintain a consistent effect across different tissue types. This
adjustment is based on the power setting and the level of tissue impedance. The
system controls maximum output voltage to reduce tissue damage and to
minimize sparking.
