Selection of coagulation mode
Pressing the coagulation mode selector on the front panel, selects the
appropriate coagulation mode (SOFT, AUTO STOP or FORCED) for the type of
surgery and accessories to be used. Figure 5.2 shows the display with the soft
mode selected.
Figure 5.2
The “SOFT”, “AUTO STOP” and “FORCED” coagulation modes have the
following characteristics:
• Output is disabled until both cut and coagulation modes are
selected.
• The coagulation mode selecting cannot be changed while
output is activated.
SOFT:
To stop light bleeding, as well as mark tissue using snares.
Very little tissue carbonization occurs in this mode.
AUTO STOP: To reduce tissue carbonization and invasion, output is
automatically stopped when a certain degree of coagulation
has been reached during SOFT coagulation.
FORCED:
Comparatively strong coagulation and hemostatic effects.
