What is high frequency?
High frequency is an electric current that is generated in the hf1 SURG®medical with a frequency of 1.2 MHz ( 1 200 000 cycles per second). This energy of 1.2 million cycles/sec concentrates on the tip of the electrode. As soon as an electrode gets in contact with the tissue, the cell liquid expands, the cell explodes and evaporates, which causes the cutting or coagulation effect. Units that work in the Megahertz range produce the cutting and coagulating effect quicker, which in turn prevents thermal damage in the adjacent tissue. The electrode itself serves only as conductor and does not get hot. This can be very well demonstrated with an activated electrode being held against a blown-up balloon. As heat develops only within tissue the balloon does not burst.
