Abstract

A thermotherapeutic RF apparatus with multiple probes workig in time-share mode is composed of a thermotherapeutic bed, 2-6 pairs of probes, and RF power source. A switching switch is connected between said probes and RF power source for making said probes to work alternatively.

Description

Radio frequency multi-electrode time-sharing work heat treatment unit
One, technical field
The present invention relates to a kind of armarium, particularly a kind of radio-frequency (RF) thermotherapeutic equipment of multi-electrode time-sharing work, various applicable to treatment to the effective disease of thermotherapy.
Two, background technology
Radio-frequency (RF) thermotherapeutic equipment is the medical equipment that the heat that utilizes radio-frequency power to produce is treated some disease, but when existing radio-frequency (RF) thermotherapeutic equipment effectively heats in the deep focus to human body, exist the overheated and deep focus of fat deposit not reach the problem of treatment temperature, as single counter electrode electric capacity heating radio-frequency (RF) thermotherapeutic equipment, the SR-1000 type heat therapy machine that the Thermotron-RF thermal therapeutic apparatus of Japanese YamamotoVinyter company and domestic Shenzhen group of SAST produce all uses this kind working method.The heat treatment unit of this mode because of following two former thereby make the temperature of fat deposit under when treatment electrode more a lot of soon than the temperature rise of other tissue of inside of human body, cause when the treatment region temperature does not reach the treatment temperature as yet, the fat deposit temperature has been elevated to and has made the intolerable temperature of people, even makes human body produce scald.Reason one is that the radio-frequency (RF) energy of fatty tissue absorption is more than other tissue such as muscular tissue; Reason two is that the heat capacity ratio of fatty tissue is organized much smaller than other, and fatty tissue had both made the heat of absorption be lower than muscular tissue, but its temperature rise still can be faster than other tissue.In order to improve the fatty tissue problems of excessive heat, multi-source multi-electrode mode radio-frequency (RF) thermotherapeutic equipment also is used, and as the thermal therapeutic apparatus that domestic Jilin Province Mai Da technology ﹠ development Co. makes, is the mode of using double source two counter electrode to work simultaneously.Though the heat that fatty tissue obtains under the electrode of this mode is few than first kind of mode, the problem of its existence is made moderate progress, it is limited to improve effect, and still there is more serious fatty problems of excessive heat in promptly this mode.
Three, summary of the invention
The purpose of this invention is to provide a kind of can the treatment, can not scald the radio-frequency (RF) thermotherapeutic equipment of its hetero-organization of human body simultaneously,, improve thermotherapy effect to improve fatty problems of excessive heat to the deep tissue disease.
To achieve these goals, radio frequency multi-electrode time-sharing work heat treatment unit of the present invention, comprise thermotherapy bed, electrode and power radio frequency source, it is characterized in that described electrode crossing setting, be connected with change-over switch between electrode and the power radio frequency source by the alternation of control circuit control electrode.Wherein electrode can be made up of the 2-6 counter electrode.
Described radio frequency source produces the radio-frequency power that needs and also is fed to the high-power change-over switch of electronic control radio frequency, change-over switch be responsible for power feed that timesharing ground produces radio frequency source to each on the capacitance electrode.
Lie in the patient who accepts thermotherapy on the thermotherapy bed, same electromagnetic field that the position that need are treated places each that capacitance electrode is produced at synchronization, has only a pair of capacitance electrode to have radio frequency electromagnetic field to produce, and other electrode does not have radio-frequency power.
The present invention compared with prior art, its remarkable advantage is: during the patient accepts thermotherapy, the home court district of every counter electrode all should cover the position that the patient need treat, in a certain moment of treatment, as long as have power arranged on the pair of electrodes, then therapentic part all has the effect of rf electric field, and promptly focus is in heated condition all the time.And the fat deposit under certain pair of electrodes just is heated, when other electrode has power only when this counter electrode is added power, this pair of electrodes inactivity, fat deposit is not heated, and because the heat capacity ratio of fat deposit is lower, so this fat deposit is in the fast cooling state.Promptly during this counter electrode adds power, fat deposit temperature raise fast, during not adding power, lowered apace again, the temperature that makes patient's subcutaneous fat is rapid fluctuations up and down in certain temperature range just, and the temperature of treatment region tissue, it is temperature required to reach treatment after heating through certain hour, thereby plays effective therapeutic effect.

Five, the specific embodiment
Embodiment 1: with two electrodes is example, as shown in Figure 1.This radio frequency multi-electrode time-sharing work heat treatment unit comprises thermotherapy bed 1, two pairs of capacitance electrodes 2, power radio frequency source 3 and double-point double-throw switch 4.In two counter electrode, a pair of vertical setting, a pair of being horizontally disposed with, its cross point just in time can be dropped on the focus that lies in the patient on the thermotherapy bed, and when certain pair of electrodes was applied in radio-frequency power, the generation radio-frequency field acts on the patient between its electrode needed therapentic part.Electrode is connected with power radio frequency source 3 by double-point double-throw switch 4, and wherein the frequency of radio frequency source 3 is 40.68MHz, and peak power is 1500W.Double-point double-throw switch realize the function that radio-frequency power switches between two counter electrode, and control circuit 5 is a prior art by the control of control circuit 5.
Utilize above-mentioned heat treatment unit that body weight is tested for the live hog of 48Kg and obtain temperature curve Fig. 2, Fig. 3.Curve is that heat treatment unit is operated in not under the switching state among Fig. 2, and upper/lower electrode is heated pig, uses power to be 800W.In experiment, use the anti-interference Bowman temperature sensor of high impedance real-time continuous thermometric, the intraperitoneal of curve a point for measuring temperature about distance skin 10cm, in the fat deposit of curve b point for measuring temperature about subcutaneous 1.5cm, and near Musclar layer.
Comparison curves a and b as can be known, the temperature of fat deposit rises soon than intraluminal tissue temperature, when intraluminal tissue had just reached 38 ℃, fat deposit reached 48 ℃ soon, was easy to occur fat deposit and perienchyma and scalded.
Among Fig. 3, when the self-timing switching state, be every pair of work one minute switching time, comparison curves c and d, and the temperature rise of visible intraluminal tissue does not have big variation, and the fat deposit temperature rise is slow many, has realized purpose of the present invention preferably.
Embodiment 2: with three counter electrode is example, and as shown in Figure 4, this radio frequency multi-electrode time-sharing work heat treatment unit is substantially the same manner as Example 1, and different is the quantity of electrode.In this example, electrode is three pairs.The frequency of utilization of power radio frequency source 3 is 40.68MHz, and peak power is 1500W.Change-over switch 4 is the DPTT double-pole triple throw switch, realizes function that radio-frequency power is switched between three counter electrode, switching position and switching time controlled circuit 5 control.Electrode 2 is three counter electrode, and three counter electrode adds the lesions position that the patient all should be aimed in the thermal center (-tre) during treatment.
Equally, the present invention also can be designed to four counter electrode, five counter electrode, six counter electrode, even multi-electrode more, but all is the radio frequency multi-electrode time-sharing work heat treatment unit of alternation of the present invention.
