2.1 Intended Use
The electro surgical unit HBS X-touch 300 argon BiSeal® is intended to cut and to coagulate various
tissues during different surgical disciplines.
2.2 Monopolar operation
In the monopolar mode, HF current is applied to the tissue using
an active electrode. The cutting or coagulation effect is caused by
a high concentration of current, i.e. a high current density over the
small surface of the active electrode. This generates an increase
in temperature, causing the water from the tissue immediately
surrounding the active electrode to vaporize. Depending on the
intensity of the HF current, this causes bleeding to stop or
generates a cut in the tissue.
The HF current flows from the active electrode to the neutral
electrode and is distributed over its large surface. This reduces the
density of the current in this area, and generally prevents
unwanted thermal effects at the position of the neutral electrode.
The current flows back to the electrosurgical unit through the
neutral electrode.

In the bipolar mode, the current path is limited only to tissue located
between the two electrodes of a bipolar instrument.
Use of the neutral electrode is not necessary. Bipolar application
does not entail any risk of the current flowing through the patient's
body. Consequently there is no danger of burns due to a poorly or
incorrectly positioned neutral electrode.
Bipolar coagulation is therefore safer than the monopolar method
and is particularly recommended for patients with pacemakers or
for operations on organs with a small diameter.
