Fig. 3.3
Schematic representation of electro-coagulation on a homogenous tissue: The boiling extends to
a depth somewhat larger than the diameter of the electrode. It is strongest underneath the
electrode. At the surface it also extends to the surroundings of the electrode (rim effect).
Fig. 3.4
Schematic representation of electro-coagulation with generated eschar: In this case the current
value used for electro-coagulation is too high. Close to the electrode a coagulation of tissue is
initiated so rapidly that eschar is created, the isolating effect of which prevents a deeper
electro-coagulation. Due to eschar the electrode sticks to the tissue.
