At least one electrode 110 of at least another electrode 110 is enclosed in subpackage, and in more energy the skin under skin surface is sent to
Volume, less energy is sent in the sense that skin surface the effect of the energy transmission for strengthening phase controlling.It is not bound by opinion
Constraint, utility model people believe, the encirclement configuration of electrode prevents or reduce to carry out the horizontal (namely in skin of self-electrode 110
Surface level) transmission of RF energy, therefore significantly reduce skin surface heating.On the contrary, more RF energy vertically or with
Certain angle is sent under surface, so as to the energy of most of transmission actually heated it is specific under skin surface
Skin volume.Most symmetrical configuration is coaxal electrode 110.Such configuration can maximize current convergence effect.But, this
Utility model is not limited to the configuration with coaxal electrode, and including partial concentric, electrode that is eccentric and surrounding in various degree
110.Any encirclement electrode 110 and besieged electrode 110 can have different shapes, such as circle, annular, ellipse, portion
Cyclotomy is annular, linear etc..
Comparative electrode polarity can determine according to specific purpose, requirement and configuration, and be dynamically varied.For example, may be used
Control comparative electrode polarity, has phase to produce an inner most electrode 110A for outer electrode 110B to 110F
Anti- polarity.In another example, can control comparative electrode polarity, with produce internal electrode group (such as 110A in Figure 1A,
110B and 110C), there is contrary pole for set of outer electrodes (such as 110D, 110E and 110F in Figure 1A)
Property.Although view shows six electrodes, but similar concentric arrangement is designed with any number of electrode 110, with unrestriced

The shell 101 of equipment 100 can be arranged to holding electrode 110 and the electronic circuit for operating electrode 110.Shell
101 can ergonomically be designed by meeting, such as so as to treating described in the continuous mode application as smearing.Shell 101 can
Include ensuring that the mechanism that electrode 110 is contacted with skin.Equipment 100 can be operated with pressing button 102.Equipment 100 can be arranged
It is by being operated with different intensity with different pattern (repetition, continuous etc.) pressing buttons 102.One or more RF generators
Can be outside and connect or inside shell 101 via cable 99.Power supply can be sensing.As the application it is detailed
Description, RF generators can be adjusted by RF pressure regulators and controlled by the control unit of such as microcontroller.Described control unit
Can associate with trigger and low pressure pressure regulator.Described control unit can be further arranged to control each electrode 110A and arrive
The phase place of 110F, and coordinate the polarity of electrode.Therefore, described control unit can be arranged to arrange any two electrode 110
Between any specific phase place, be sent to skin to be accurately controlled energy.Specifically, control unit may specify on the contrary
Polarity to electrode 110 subgroup.Contrary electrode can be analogous to as mentioned above that (namely unnecessary is 180 ° and can
Being such as 120 ° or 160 ° etc.).Phase contrast between electrode 110 can be predetermined, and can be during operation
Controlled or kept constant in predetermined phase place.The transmission plan may include to control comparative electrode polarity, to incite somebody to action
The RF energy of transmission concentrates on specific skin volume.For example, comparative electrode polarity is can control, to produce with roughly the same
The one or more pairs of neighbouring electrode 110 of polarity.Control unit can be arranged to control at least one portion surround electrode and
At least part of comparative electrode polarity of besieged electrode, to form around the latter gesture in specific skin volume

Electrode 110A-110F all can be connected to single generator or several generators, the generator via transformator
Can be used to RF energy is provided to electrode 110.Paired electrode configuration (being connected to the two poles of the earth of generator with electrode) is in domestic
It is probably practical in equipment, to reduce the number of generator, and because the business machine used in professional clinical is arranged
There can be multiple ground connection generators, each provides single electrode.Some electrodes in electrode 110A-110F are attached to one
Rise, to improve electric current transmission and heat.Therefore, the equipment 100 with particular number of generator can be used to via by by one
A little electrodes are connected to the electrode of the greater number of single generator, by the transmission of RF energy.
In some embodiments, control unit can be further arranged to obtain the real-time estimation and root of Skin Resistance
Skin Resistance according to estimates adjusts the energy of transmission, causes more predictable result.Skin Resistance is estimated can be from relative to applying
Plus voltage for measure energy transmission obtain (Skin Resistance with treatment skin volume and increase).Different energy can be applied
Amount passes a parameter to process different skin areas, and (such as, in face and ocular, feature is the thin skin that scope is 1 millimeter
Skin, and cheek region is the thin skin skin that feature is scope 3-4 millimeter).
In some embodiments, the skin treatment for being carried out using equipment 100 can be with reference to any other processing method, such as
Light or ultrasound transmission, coating gel, facial cream, external preparation etc..
Some embodiments may include diameter (2RA) it is central disc shape electrode 110A between 4 millimeters to 12 millimeters,
