Electrodessication is evaporation of cell liquids with a subsequent destruction of
subcutaneous cells. Evaporation is caused by thermal energy generated by oscillating spark
discharge. A relatively low electric power, at maximum 1.8 W is applied and as it affects only
a small area, it is able to cause the evaporation of cell liquids.
Electrocoagulation is a process in which thermal energy of the spark discharge causes
evaporation of water in cells and it disrupts their structure. High temperature causes
coagulation of tissue and blood proteins, which is used for stopping a small bleeding
–
to
closure of small veins with a diameter of 2-3 mm. The treated area is stimulated by spark
discharge with a creation of plasma at the distance of 2 mm from the skin. The discharge is
applied with a smaller power (1.8 W), compared to common electrocauters. Concerning the
fact, that this power works in a very thin discharge beam and treats only a small area, there
appears a considerably good local coagulation effect without a need to sterilize the application
tip.
Electrodessication, electrofulguration or electrocoagulation can be used for the
treatment of various indications in various medical fields. A detailed summary of application
possibilities will be a subject of training together with the handover of the device. The device
can be used in classical surgery, dermatology, gynecology or dental medicine.
At medium intensities (5-6) when there is no considerable destruction of skin cells, the
device is used for the treatment of small veins, couperosis, scars and stretchmarks or pigment
spots. Here, the thermal energy of the spark discharge is used for the removal of skin cells
with accumulated melanin. These intensities can be satisfactorily used for the veins removal.
The spark discharge also opens Na/K channels of cell membranes in skin cells.
Together with this, being generated by AC voltage with a minus pole on the tip, it is able to
help with the absorption of various serums of negative ions character into the skin. Unlike
other technologies, it works with a higher energy and a doctor is able to apply an optimal
amount of serum very effectively. The desired effect is supported by the simultaneous
opening of Na/K channels and the heat generated by the spark discharge.
At the lowest intensities (1-4), the spark discharge is used solely for aesthetic
treatments that can be a supplement to a medical treatment or an extension of the offering of
medical clinics or ambulances. The spark discharge generates a flow of negative electrons and
positive ions. The discharge is generated by the DC current and there is a negative pole at the
tip of the device. Most of cosmetic preparations contains negative ions that are very well
processed thanks to the polarization. These intensities are used for lifting, treatment of
wrinkles and rejuvenation.
