3 Intended Use and Working Principles
3.1
Intended Use of the Martin maxium
The maxium is an electrosurgical generator designed for the electrosurgical cutting and coagulat-
ing of living human or animal tissue.
The safe application of electrosurgery requires that the user has familiarized himself/herself with
this type of technology and how it can be used in practice for therapeutic purposes.
With the maxium, Gebrüder Martin provides you with an HF unit that incorporates the most ad-
vanced technology, not least for the safety of the patient.
The maxium HF unit is a highly versatile system with monopolar as well as bipolar cutting and co-
agulation capability for use in micro- as well as macrosurgery.
3.2
The Monopolar Working Principle
The maxium HF electrosurgical unit is a generator that converts the electric energy supplied by the
mains into a high-frequency current. Via a supply lead, this HF current is then delivered to a handle
before reaching the dot-shaped (pointed) active electrode. At the point of contact or application, a
high field density is generated in the surrounding tissue. It is this high energy concentration which
produces the desired electrosurgical – i.e. thermal – effect in the area around the active electrode.
Subsequently, the current flows through the patient's body up to the large-sized neutral (or disper-
sive) electrode, a process that is accompanied by decreasing current density. Thus, if used as in-
tended, this method ensures that no thermal effect is produced in the body region where the neu-
tral electrode is attached. The circuit is then closed via the neutral electrode’s connecting cable
(lead).
For monopolar applications, the HF generator can be activated either with the footswitch or with
finger switches in the form of pushbuttons provided on the surgeon's handle.
