5.6.13. GastroKNIFE 3 (optional)
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
This function is available if the device has the options argon / GastroCut
(900-391).
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
