5.6.13. GastroKNIFE 3
This mode is used in gastroenterology. Instruments for papillotomy and
endoscopic resections are used for cutting and coagulation. ARC control
generates the cutting effect with simultaneously minimized output power.
This mode consists of a pulse sequence of cutting current and coagulation
phase. With an accelerated fast pulse rate of 2.2 cutting pulses per second,
this mode is suitable for advanced users.
Application areas
Papilla incision using a papillotome and flexible endoscopy, resection with
needle knives; accelerated fast pulse rate for advanced users.
Suitable instruments
Papillotome
Needle knives
5.7. Monopolar coagulation modes
5.7.1. Moderate
This mode is used with contact coagulation to stop hemorrhagic oozing, for
hemostasis of relatively large tissue areas, and for small-area coagulation.
Tissue carbonization is prevented and electrode adhesion to the tissue is
strongly reduced. Greater coagulation depth is achieved in this mode than
in other coagulation modes. The degree of surface scabbing can be
controlled by adjusting the "Effect" setting in the range of 1 to 3.
Application areas
Coagulation with relatively high penetration depth; low electrode adhesion
to tissue
Suitable instruments
Electrodes with large contact areas, such as ball electrodes
