6.3.7. Program 6 "Gastro LOOP" (only with GastroCut option)
This program is used in gastroenterology.
In this program, polypectomy snares are used for cutting and
coagulation.
Arc control technology generates the cutting effect with simultaneously
minimized output power.
ARC control facilitates immediate cutting and prevents adhesion of the
electrodes.
The degree of coagulation increases with an increasing blend factor.
The connection port 29 has no function with the programs
"Gastro LOOP" and "Gastro KNIFE".
Three modes are available in this program:
fast (approximately 3 cutting pulses per second),
medium (approximately 1.6 cutting pulses per second) and
slow (approximately 1 cutting pulse per second).
For more information on "GastroCut" mode, see section "GastroCut"
mode, page 27.
