Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to coordinate specification to be taken off
The content shown, so that those skilled in the art is understood with reading, is not limited to enforceable qualifications of the invention, therefore
Do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influenceing the present invention
Under the effect that can be generated and the purpose that can reach, it all should still fall and obtain the model that can cover in disclosed technology contents
In enclosing.Meanwhile, the term of cited such as " on ", " under " in this specification, "left", "right", " centre " and " one " is also only
It is easy to understanding for narration, and is not used to limit enforceable scope of the invention, its relativeness is altered or modified, without essence
Change under technology contents, when being also considered as enforceable category of the invention.
It is to allow positive and negative radio-frequency electrode to carry out current lead-through by skin histology in existing lattice radio frequency treatment technology, from
And skin treating is realized, the radio-frequency electrode on its therapeutic equipment is generally adopted by row's method of array, as shown in figure 1, showing
The arrangement schematic diagram of radio-frequency electrode in existing lattice radio frequency therapeutic equipment, as illustrated, also identifying each radio-frequency electrode in figure
Between current direction distribution signal, because, electric charge will be moved along the minimum direction of resistance, therefore the negative pole A in figure
Between positive pole D, because there is the current direction B at opposite electrode B or C, electrode A without flowing to D points.In addition,
Electrode B provides current path for electrode C and electrode A simultaneously, therefore is mutually folded at electrode A and electrode C by electric current B electric current
Plus.
So, energy over the course for the treatment of is by formula Q=I2* R*t is calculated, wherein, Q is energy, and I is that electric current is big
Small, R is the impedance (equivalent to resistance) of skin, and t is the time for flowing through electric current.And anode electrode B and D are set all using equipotential
Mode, electric current is I, then the electric current at electric current A is that electric current is 1.5I at 0.5I, electric current C.
In addition, below by several arrangement methods for having lattice radio frequency in radio-frequency therapeutic equipment, it is equally to use again
Above-mentioned circuit connection structure, only changes the arrangement mode of radio-frequency electrode.Such as Fig. 2A, show in the prior art wherein
A kind of arrangement of radio-frequency electrode, wherein, positive pole negative pole is dot matrix, sets positive electrode current (i.e. at electrode A CE electric as I
Stream is I), then the electric current of electrode B is 1.5I, and electrode D electric current is I, electrode F electric current 0.5I.So, in actual use mistake
B electrode current densities are 3 times of F electrodes in journey, are 1.5 times (see Fig. 2 B) of ACDE electrodes.
Further, see Fig. 2 C, show another lattice radio frequency electrode arrangement schematic diagram, wherein middle lattice-like is equal
For positive pole, edge strip for negative pole, correspondingly, Fig. 2 D are the schematic diagram after the lattice radio frequency electrode current is heated,
It is can be seen that from Fig. 2 D in middle positive pole radio-frequency electrode, its Energy distribution is relatively uniform, and the negative pole radio frequency in edge
Then there is tilt phenomenon in electrode, its Energy distribution.
From the point of view of to sum up, in existing RF therapy, its RF energy taken transmitting treatment mode of operation is present
Capacity volume variance on the treatment face of conspicuousness, so as to cause therapeutic dose uneven.

The resistance R1 other end connects the base stage of the triode Q1；The colelctor electrode of the triode Q1 connects the relay KA and reached the standard grade
One end of circle, the other end connection power supply VCC, the triode Q1 of the relay KA coils emitter stage connects output ground
(or connecing equipotential end).
In actual circuit, above-mentioned radio-frequency electrode drive circuit is played to be arranged between radio frequency source and radio-frequency electrode
The effect that driving radio-frequency electrode is turned on or off with the radio frequency source.Wherein, the resistance R2 plays a part of current limliting, works as driving source
When connection or arrival so that photo-coupler turns on and then passes through resistance R1 electric current increase, the i.e. electricity of the base terminal of triode
Pressure rise, so that triode ON, at this moment the coil electricity on relay and adsorbs normally opened end and makes radio-frequency electrode and radio frequency source
Be connected conducting.Here the purpose for setting photoelectrical coupler is to prevent radio-frequency electrode or radio frequency source will not when occurring unexpected
Driving source is had influence on, so as to ensure that the security of circuit.
If it should be appreciated that directly driven by relay and triode radio-frequency electrode work can also, only its
Lack certain security.Additionally, it should be appreciated that the triode is NPN type, it is between photo-coupler and relay
Connection method, is not referred to, then it is all connection method known to those skilled in the art if above-mentioned, therefore is no longer gone to live in the household of one's in-laws on getting married here
State.
