Background technology
Radiofrequency melting instrument is under ultrasound or CT guiding, and single needle or multi-needle electrode are pierced into patient tumors position, when penetrating
Frequency generator produces radio-frequency current（460KHz）When, by wire electrode exposed in electrode needle make its surrounding tissue produce at a high speed from
Son vibration and friction, are then converted into heat energy, and its heat energy gradually conducts with the time to periphery, and local temperature reaches as high as 120 DEG C
（Temperature is adjustable）, so that thermal coagulation necrosis and denaturation occur for local organization cell, reach ablation purpose.Carry out at this stage
Medical radiofrequency melting instrument, when carrying out tumour ablation using conventional single electrode pin, because of the influence of thermal radiation, only to diameter
Below 3cm tumour obtains the effect of consistent with surgical operation, in order to carry out ablation to the larger tumour of volume, adopts at present
With three kinds of optional therapeutic schemes.First, carrying out the overlapping ablation in more sites using single electrode pin, i.e., the larger tumour of volume is carried out
Multiple overlapping ablation, such therapeutic scheme is not only time-consuming, and increases operation difficulty, while is readily formed ablation holiday
Domain, the residual of tumour is caused to recur；Second, use claw type electrode needle, ablation is carried out after knub position expansion, but this
Kind of scheme also only obtains good therapeutic effect to below diameter 7cm tumour, the ablation stove not being suitable for more than diameter 7cm,
, also can only be by the way of repeatedly treating simultaneously when patient's body has multiple tumours；Third, external switching controller is used,
Guide multiple single electrodes to carry out combined synchronization treatment for the larger tumour of monomer, or multiple tumours treat simultaneously, but
It is external switching controller and radiofrequency melting instrument occasionally there are equipment matching problem, adds potential safety hazard, at the same it is also extra
Add the procuring equipment expense of hospital.
The content of the invention

Go out the come off signal input part of detection module of end and indifferent plate electrode to electrically connect, the indifferent plate electrode comes off detection module, pin
The signal output part for stepping on switch electrically connects with the signal input part of single-chip microcomputer, and the signal input part of the single-chip microcomputer is respectively with showing
Show the signal output part electrical connection of module, keyboard input module, power management module, multi-electrode pin state detection module；Institute
Single-chip microcomputer is stated to connect with communication interface modules communication；The signal of module occurs with Multi-channel high-frequency electric current for the signal output part of single-chip microcomputer
Input electrically connects, the Multi-channel high-frequency electric current occur the power output end of module respectively with first, second, third radio frequency
The power input electrical connection of ablating electrode pin, the signal output part of first, second, third radio-frequency ablation electrode needle with
The signal input part electrical connection of the multi-electrode pin state detection module；The multi-electrode pin state detection module is by
First, second, third electrode needle state detection module is formed, and it is high by first, second, third that module occurs for the Multi-channel high-frequency electric current
Module composition occurs for frequency electric current.
The utility model advantage be it is simple in construction, using easy to operate.Without extra auxiliary equipment, you can carry out body
The multi-electrode synchronous therapeutic of the larger monomer tumour of product, can also carry out the synchronous therapeutic to multiple tumour bodies simultaneously, save significantly
Treatment time has been saved, has improved therapeutic effect；And possess indifferent plate electrode and come off automatic detection warning function.
