The high-frequency electrosurgery also called cutting and vaporization electro-surgery has been appreciated from research and published works by Maness and collaborators in 1978 when they defined the ideal frequency for vaporization and cutting 4,000,000 cycles per second or 4 MHz, with a direct relationship between frequency of the current and lateral heat that determines the quality of healing and cut similar to cold blade scalpel. This is a process of cutting and / or coagulation atraumatic tissue using an alternating current of high frequency. As an introduction, it is important to emphasize that the vaporization, cutting and cauterizing electro surgery is a completely different physical process of the one when the heat from an object is passively transferred to the tissue. The temperature increase occurs within the secondary tissue to heat transfer, gradually leading to evaporation of intracellular water until it reaches a point where the proteins start to denature and coagulate. This results in cell death by desiccation and carbonization.
In contrast, electrosurgical cutting and coagulation are achieved when a high frequency current passes through the tissue leading to a more rapid temperature increase than in cauterization, which results in intracellular boiling by elevating the temperature to 100 ° C instantly, causing expansion and rupture of the cell membrane (cell implosion), a phenomenon known as vaporization. For being so similar, it is important that the thermal cauterization and high frequency electro-surgery processes are not confused.
Electrosurgery generally works with alternating current. This means that the polarity of the current alternates (+/-) causing the positively or negatively ionized intracellular particles to move up from one side to another in search of its opposite pole. When the current frequency is very high (4,000,000 cycles per second) intracellular movement is so big that it generates heat raising the temperature rapidly to 100°C causing intracellular boiling, expansion and explosion, a phenomenon known as vaporization.
The "SmartShot" function is automatically activated during fractional-microneedle procedures that we use for revitalizing the skin or mucous membrane.
The unique "SmartShot" function allows for fractional control of random pulses or distribution of energy at equal distances, using radio frequency "RF" technology for precise supply of sub ablation power, which acts on the dermis and minimally damages the epidermis. Thanks to the "SmartShot" automatic function the microablative fractional radiofrequency (MAFR) treatments are extremely safe, because at the time of the procedure, after pressing the activator pedal, 64 needles on the fractional tip are not supplied at the same time, and the energy supply is random divided into columns of eight needles. The two columns at the base do not shoot in sequence, thus preventing adding a thermal effect. This effect known as relaxation time allows sufficient cooling of the tissues adjacent to the site of interaction in a completely intact and healthy state, which allows neocollagenesis and neoelastogenesis at this site. Under the influence of RF pulses, the regeneration of the dermis is accelerated by stimulation of fibroblasts for the synthesis of collagen and elastin fibers as well as regeneration of the epidermis thanks to the migration of keratinocytes.
- The effect of renewing and firming the skin surface: renewing the surface of the skin involves the revitalization of old collagen fibers by re-shrinking them and synthesis of new fibers.
- No formation of large scabs: Unlike dermal abrasion and deep peelings, the microablative fractional radiofrequency (MAFR) produce micro crusts, leaving in the treated area on five to seven days average after treatment.
- Recovery time reduced to a minimum: this method provides very fast recovery, which allows for almost immediate return of patients to daily activities
