Paper Abstract

The number of sparks per time window between a scalpel electrode and tissue is a measure of the electrosurgical cutting ability with a strong dependency on the electrical power dissipation. This parameter used as controlled variable in an appropriate circuit allows controlling electrosurgical treatments with best cutting quality at any kind of tissue. It is presented the effect of this control unit with regard to therapeutic aspects and smoke emission. Histological investigations of porcine muscular tissue reveal drastically reduced boiled zones and zones of oedema formation at controlled cuts in comparison to common uncontrolled treatments. A further comparison of the harmful components in the electrosurgical smoke shows the great advantage of the new system.
