Abstract
An external RF therapeutic apparatus for prostatic disease has two pairs of electrodes placed orthogonally for increasing the field intensity by 1.4 times, the absorption power by about one time and the temp of position to be treated, resulting in high curative effect. A skin-cooling unit is used to prevent burn of skin and caking of subcutaneous fat. Its RF generation controller works in separate-excited mode for higher stability and curative effect.
Description
The invention belongs to electromedical equipment, particularly a kind of external radio-frequency therapy apparatus for prostate gland.
As everyone knows, hyperplasia of prostate is a kind of Senile disease of common pilosity, according to statistics, suffers from this disease the male of China more than 50 years old 50%, male more than 80 years old then 100% suffers from this disease, medication effect is little, big and the poor effect of operation risk, in view of this, various electromedical equipments occur in succession, the patient suffering was difficult for promoting when radio-frequency therapeutic equipment was because of treatment in the microwave therapy apparatus in some interior therapeutic instrument such as the body, body, in recent years, single capacitive electrode external treatment instrument has appearred again, product of neat electronic medical instruments factory and Shanghai Communications University is representative to the east of it, and they produce by radio frequency, and control system drives a pair of capacitive heating electrode and the treatment frame is formed, and its radio frequency produces control system and adopts free-runing operation.Though this kind equipment has external treatment, the painful little advantage such as acceptant of patient, but its weak point is: during treatment, this is just placing patient's prostatic to the capacitive heating electrode, place, the back side, coming down to a human body is between two electrodes as electrolyte, the no radio frequency focusing ability of this counter electrode itself, be difficult to improve the treatment temperature of prostatic, weakened therapeutic effect, and between electrode the normal structure of human body particularly the subcutaneous fat of skin and abdominal part be stranded to bear to cause behind the higher temperature and burn or lump, the patient is done not feel like oneself, add radio frequency generation control system and adopted the self-oscillation working method, its frequency stability is poor, easily causes gap vibration and failure of oscillation, for use is made troubles.
At the shortcoming of above-mentioned external radio-frequency therapy apparatus for prostate gland, the objective of the invention is to design a kind of electrode structure with radio frequency focusing ability, and therapeutic instrument working stability, reliable, to improve therapeutic effect, be China old people's health, make bigger contribution.
Consider that prostate is in human body lower quadrature center, confirm according to present inventor's proposition and by computer simulation: the energy that medium absorbed in crossed electrode centre will be two radio frequency sources superpositions of effect separately, and, then do not have this superposition situation at other position of human body.The present invention of Ti Chuing is the external medical apparatus for treating prostatic diseases of crossed electrode for this reason.Formation block diagram such as Fig. 1 of this therapeutic instrument, it is made up of radio frequency generation control system 1, two counter electrode 2, treatment frame 3, skin heat sink 4.The patient lies on the treatment frame during treatment, and two counter electrode place the place, all around of the corresponding prostatic in human body bottom.The skin heat sink is installed under the treatment frame, facing to treatment site.
Radio frequency produces control system circuit block diagram such as Fig. 2, adopt it to swash working method, by a control station 5 regulating and controlling radio frequency sources 6, and the vibration wavelength-division two-way that will produce is delivered to two radio-frequency (RF) power amplification 7,8 respectively, the high-power RF signal that the output of its generation is adjustable is sent into two human body matching networks 9,10 more respectively, make radio-frequency (RF) energy enter human body effectively to regulate coupling, drive two counter electrode 11,12 and 13,14 continuous separately and that quadrature is placed again respectively.
Single electrode structure such as Fig. 3.Each electrode is made up of the circular metal plate 15 that is wrapped in the low insulant of high-frequency electric field loss 16, and is connected to the output matching circuit of radio frequency source by plain conductor 17.Patient's safety was considered therapeutic effect when this had guaranteed treatment, and the electrode stock size is selected between φ 140mm～180mm.Two counter electrode quadratures of the present invention are placed, about making the prostatic of being treated radio frequency power density is doubled because of radio-frequency field superposes, its field intensity average has increased by 1.4 times, its absorbed power average has increased by one times, improved therapeutic effect greatly, the normal structure place does not then have this heat doubling effect.
During treatment, because this therapeutic instrument belongs to electrotherapy and thermotherapy, though heat mainly concentrates on the prostatic of being treated, but human body skin also may be perspired because of heating inevitably, because of being with salt in the antiperspirant, radio-frequency field is concentrated caused skin to cross thermal burn, the present invention has set up the skin heat sink for this reason, its structural representation such as Fig. 4, it is made up of blower fan 18, air-guiding aisle 19 and bracing frame 20.Bracing frame 20 is used for supporting air-guiding aisle 19, and blower fan 18 is fixed in the air-guiding aisle 19, and wind-guiding air channel 19 places the treatment frame to aim at the patient treatment position down.The power supply of blower fan 18 is received the outfan that radio-frequency power is regulated the autotransformer of usefulness, when radio frequency power output increases, patient's prostate place temperature raises, when patient's lower part of the body skin volume of perspiration increases, voltage on the blower fan 18 will increase thereupon, the exhaust air rate of blower fan 18 increases, the wind orientation that air-guiding aisle 19 just produces blower fan 18 is delivered to patient's prostate corresponding in vitro position under the treatment frame, dry up perspiration, play the cooling effect of self adaptation skin, skin burn and subcutaneous fat agglomeration problems when further having solved treatment.
Adopt crossed electrode external radio-frequency therapy apparatus for prostate gland of the present invention, adapted to the situation that prostate is in human body lower central position, compared with the prior art, during treatment, prostatic absorbed power meansigma methods has increased nearly one times, promptly improve the temperature of prostatic, thereby improved therapeutic effect, correspondingly shortened treatment time; (can need 2.5 hours reduce to 2 hours from original treatment) be added and increased the skin heat sink, alleviated greatly that patient skin is burnt and the subcutaneous fat caking phenomenon, further protected patient's non-treated area; Because producing control system, radio frequency of the present invention adopted a control station to divide the independent control of two-way difference and drive two counter electrode and its sharp working method that quadrature is placed simultaneously, working stability when making treatment, adjusting, easy to use, be a therapeutic efficiency height, the external medical apparatus for treating prostatic diseases of penetrating of practicability.
