By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
Notice, structure, ratio, size etc. that this description institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, still all should drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
In existing lattice radio frequency treatment technology, allow positive and negative radio-frequency electrode carry out current lead-through by skin histology, thus realize skin treating, row's method of array that what the radio-frequency electrode on its therapeutic instrument generally adopted is, as shown in Figure 1, show the arrangement schematic diagram of radio-frequency electrode in existing lattice radio frequency therapeutic instrument, as shown in the figure, also identify the distribution signal of current direction between each radio-frequency electrode in the drawings, due to, the direction minimum along resistance is moved by electric charge, therefore between negative pole A in the drawings and positive pole D, because have opposite electrode B or C, so the current direction B at electrode A place and D point can not be flowed to.In addition, electrode B provides current path for electrode C and electrode A simultaneously, therefore is the mutual superposition at electrode A and electrode C place by the electric current of electric current B.
So, energy is over the course for the treatment of by formula Q=I
2* R*t calculates, and wherein, Q is energy, and I is size of current, and R is the impedance (being equivalent to resistance) of skin, and t is the time flowing through electric current.And set anode electrode B and D and all adopt equipotential mode, electric current is I, then the electric current at electric current A place is 0.5I, and electric current C place electric current is 1.5I.
In addition, below by again to several arrangement methods having lattice radio frequency in radio-frequency therapeutic equipment, it is adopt above-mentioned circuit connection structure equally, only changes the arrangement mode of radio-frequency electrode.As Fig. 2 A, show the arrangement of wherein a kind of radio-frequency electrode in prior art, wherein, positive pole negative pole is dot matrix, and setting positive pole electric current is I (namely electrode A CE place electric current is I), then the electric current of electrode B is 1.5I, the electric current of electrode D is I, the electric current 0.5I of electrode F.So, B electrode current density is 3 times of F electrode in actual use, is 1.5 times (see Fig. 2 B) of ACDE electrode.
Further, see Fig. 2 C, show another kind of lattice radio frequency electrode arrangement schematic diagram, wherein, lattice-like is positive pole, edge strip be negative pole, correspondingly, Fig. 2 D is the schematic diagram after the heating of this lattice radio frequency electrode current, as can be seen from Fig. 2 D, the positive pole radio-frequency electrode mediated, its Energy distribution is relatively uniform, and is in the negative pole radio-frequency electrode at edge, and its Energy distribution then exists tilt phenomenon.
To sum up, in existing radio-frequency (RF) therapy, capacity volume variance on the treatment face that its radio-frequency energy transmission treatment mode of operation taked all exists significance, thus cause therapeutic dose uneven.
