The Electro-surgery is a process of cut and coagulation that uses a radio-frequency current. The first experiments with radio-frequency current on human subjects began between the end of the 800 and the beginnings of the ‘ 900 centuries. In 1892, Arsene d’ Arsonval (Paris) was the first to study the effects of high frequency currents on patients. It noticed that, using frequencies over 10 kHz, there was no neuro-muscular stimulation; however heat was produced. In 1899, Oudin described the destruction of tissue caused by sparks produced by current emitted by a resonant equipment, connected to a solenoid similar to the one used by d’Arsonal in his experiments. In 1907 De Forest invented the triode, an electronic tube that could amplify the signals: it was the beginning of the electronic era. De Forest with its triode succeeded in generating high-frequency currents not-damped (the old “spinterometer” systems generated damped currents) and realised a primitive device with which made the first incision on the human tissue, using a power over 70W and a frequency of approximately 2 MHz. The incision became acceptable with the invention and the use of a pentode in this type of Electro-medical equipment; however the recovery was of third intention. In 1926 some surgeons began to use this kind of equipment on their patients. In 1970 the electronic tubes were replaced by the modern device in a solid state which gave a strong impulse to the expansion and to the increase of these Electro-medical systems.


The Electro-surgery is a method to cut and coagulate the tissue quickly and without any pressure. This technique is applied with a device called “Electrosurgical generator”, an electrical equipment that generate a frequency of approximately 500 kHz and a medium power between 100W and 300W.

With the Molecular Resonance Generator a new field of applications in high radio-frequency is defined, very sophisticated, that allows a widening and an improvement of the surgical techniques. Such technology represents a remarkable evolution of the Electro-surgery practice which has been in use since many years and has, however, remarkable limitations. The Molecular Resonance technology consists in a non-traumatic cut of the tissue and a soft coagulation. The incision of the tissue, without pressure or crashing of the cells, always keep a temperature lower than 50°C. Cells close to the incision are alive since have no thermal damages at all (cells don’t get damage in fact up to 50°C). This turns out to be a great advantage both during the operation (nerve endings are not damage even going very close to them) and after it (the patient will have less pain, less charring tissue and therefore a faster recovery). This is exactly opposite to what is happening today with the conventional devices.

The incision is obtained following an emission with particular combinations of frequencies (CSS System) able to make the resonance of the weak molecular bindings of the tissue’s cells (MOLECULAR QUANTIC RESONANCE) and then, opening the cells themselves, determining macroscopically the incision. Consequently such incision will be very clear, cold, easy to heal and to recover. The absence of charring tissue reduces very much the post-operative pain.

The coagulation happens through the protein denaturation of the fibrinogenum into fibrin at a temperature of around 65°C. Even if this temperature is over 50°C, there are no problems for the tissue around the coagulated area because the heat is kept only inside the vessel which is wanted to be coagulated.


Using the Molecular Resonance generator Vesalius® the Doctor can start the operation cutting the skin, making a very nice and precise incision due to the very cold temperature on the tip and the very thin electrode used for such operation. He can also operate very close to all delicate and important areas where otherwise the only tool to use would be the cold blade. Very much important is also the fact that, using such a low temperature, the patient will have less pain and a faster recovery. The scar will also be better and less visible at the end of the whole operation and the recovery time. The Molecular Resonance generator Vesalius can also replace the Laser technology for many applications, reducing the intra-operative time, helping the doctors for being easy to be used and lowering the costs.

The result is a very innovative technique, easy to practise and usable for any surgery.
