The thermal effect of the surgical unit is influenced by a series of factors such as the current intensity, the degree of modulation and the shape of the electrode. These are the factors:
Current intensity and output power.
Degree of modulation: this is the shape of the pulses of the HF current. They depend on the generator itself and the possible settings on the electrosurgical unit. The degree of modulation may play a role in the efficiency of the cut or the depth of coagulation.
The shape of the electrode: the shape of the electrode determines the concentration of the field lines at the point of application. It therefore has an impact on the temperature of the zone and the result obtained.
The state of the active electrode: according to Joule's law, the expected effects depend on the resistance present. In addition to the physical resistance of the tissue, the resistance caused by residue potentially deposited on the active electrode must also be taken into account. It is therefore essential to always clean electrodes thoroughly during an operation.
Cutting speed and duration of the intervention.
Characteristics of the tissue: depending on their physiology, different types of tissue provide different levels of resistance.
