Problems solved by technology
When the number of electrodes is fixed, the phase angle is completely fixed. On the one hand, although this method can cause energy output between any two electrodes, although there is energy output between two electrodes that are far apart, the distance between When the two farther electrodes act on the human body, the impedance parameters at both ends will be much larger than the parameters between the two closer electrodes, so in this case, uniform heating of the area cannot be achieved, and there are still reliability problems
On the other hand, the patent application does not consider the existence of parasitic parameters, and it cannot maximize the efficiency
Therefore, just controlling the arrangement of angles cannot achieve uniform heating in the active area.

The invention discloses a variable phase array electrode device. The device comprises an electrode module, a voltage sampling circuit, a current sampling circuit, a temperature detection circuit, a main controller, a driving circuit and an impedance matching circuit. The electrode module is arranged by adopting a common electrode and a plurality of peripheral electrodes uniformly arranged around the common electrode, and the parasitic parameter influence is eliminated through the impedance matching circuit, so that the heating values in the areas enclosed by the peripheral electrodes and the common electrode are the same, and the problem of different calorific values caused by different efficiencies of a certain electrode and other electrodes is avoided.
Description
technical field [0001] The invention belongs to the technical field of electrode type electrocautery instrument. Background technique [0002] Most of the high-frequency electrocautery instruments are currently used for tissue ablation and tissue necrosis. At present, many radio frequency beauty technologies on the market are products evolved from the original high frequency electrocautery instrument. This technology is realized by changing the structure and energy of the electrodes, loading the energy on the human skin, when the high-frequency current flows through the tissue, it will generate Joule heat, using collagen at about 45-50 degrees will make the three too The chain breaks. Let the collagen undergo cell reorganization, improve cell elasticity, promote collagen regeneration, and at the same time stimulate the dermis to secrete more new collagen fiber regeneration. However, there are currently many cosmetic devices that use high-frequency electrocautery technolog...
