Functional Principle
3.1
Monopolar Functional Principle
The electrosurgical unit ME 102 is a generator that converts electrical energy from the grid into
a high-frequency current. This high-frequency current is fed to a point-shaped active electrode
via a supply line or a handle. This leads to high field line concentration in a small area at the
application site of the active electrode in the tissue surroundings of the point of contact. The
desired electrosurgical effect is achieved by this energy concentration in a small area in the
area of the active electrode. During further energy transport through the patient up to the
neutral electrode that is applied to a larger area, the concentration of the current is further
reduced. Therefore, there is, in accordance with its intended purpose, no thermal effect in the
area of the applied neutral electrode. The circuit is closed via the supply cable of the neutral
electrode.
The RF generator can be activated via either the foot switch or the finger switch on the surgical
handle.
3.2
Bipolar Functional Principle
Special constructional measures (insulation) permit design of bipolar instruments where the
active electrode and neutral electrode are positioned directly to each other. Here the path of
the high-frequency current only leads to one instrument tip to the other. Thus, there result
very short current paths and surrounding coagulation areas with low power requirements.
