The specific embodiment
As shown in Figure 1, be the technical scheme that magnetic approach adds hot lesion.The present invention includes the controller 4 of a variation magnetic field generator and a controlling magnetic field power; Described variation magnetic field generator comprises magnetic conductor 2, coil 1 that soft magnetic materials is made and signal generation and the amplifier 3 that electric current is provided for coil 1; Described coil 1 around, on soft magnetic materials magnetic conductor 2, two terminations of coil 1 take place with signal respectively and amplifier 3 two on outfan link to each other; Described controller 4 takes place by the described signal of control and the power of the big or small controlling magnetic field of output current of amplifier 3, thereby adds the treatment temperature of hot lesion to 41 ℃-44 ℃.Current signal takes place and amplifier 3 has two kinds of forms to produce current signals: a kind of is local oscillator generation electric current small-signal, provides electric current for coil 1 after the power amplification again through preposition amplification; Also have a kind of be electric current small-signal that the outside is sent here through preposition amplification and power amplification, just directly amplify if the external signal frequency just in time meets the requirements to preamplifier, provide electric current for coil 1 after the power amplification again; Will first frequency division if frequency is too high, carry out power amplification if frequency is too low again with regard to amplifying to preamplifier after the first frequency multiplication, for coil 1 provides electric current.The controller 4 of described controlling magnetic field power, it is exactly the control circuit of the power frequency of the size of current of a control coil 1 or coil 1, this control circuit can also can be operated by circuit automatically by workman's operation, can also provide information to be controlled by CPU by pick off.Its operation principle is as follows: start back local oscillator begins starting of oscillation, current signal is taken place controller 4 and the output of amplifier 3 controls to minimum, at this moment the magnetic field of Bian Huaing is in the most weak state, the affected area faradic current is also minimum, and affected area temperature increasing degree minimum is through behind the certain hour, controller 4 strengthens the power output of current signal generation and amplifier 3 lentamente, slow reinforcement is also followed in the magnetic field that changes, and the affected area faradic current also slowly increases, and the affected area temperature also slowly raises.When the affected area temperature rises to 41 ℃-44 ℃, current signal takes place and the output of amplifier 3 does not renew increasing under controller control, or reduce output a little, weaken the magnetic field of variation a little, make the affected area temperature keep a period of time, reach the purpose of treatment focus 41 ℃ of-44 ℃ of scopes.
Described current signal takes place and amplifier 3, is AC signal generator and amplifier, also can be that pulse signal takes place and amplifier.
As shown in Figure 2, be the technical scheme that the electricity consumption field type adds hot lesion, the present invention includes the controller 24 of a field generator and a control electric field strong and weak; Described field generator comprises first pole plate 22, second pole plate 23 and the signal generation and the amplifier 25 of voltage and current is provided for first pole plate 22, second pole plate 23; Described controller 24 is controlled the size of current that flows through focus between first pole plate 22 and second pole plate 23, thereby the temperature of affected area is controlled at 41 ℃-44 ℃ treatment temperature by the output size of described signal generation of control and amplifier 25.The temperature rising amplitude of focus is relevant with the size of current that flows through focus, and the electric current that flows through is big, and the focus temperature raises soon, increasing degree is high, otherwise then little.Voltage height between first pole plate 22, second pole plate 23, the electric current that flows through focus is just big, and it is just little that voltage hangs down the electric current that flows through focus.Electric voltage frequency height between first pole plate 22, second pole plate 23, the focus impedance is big, and the focus power consumption is big, and heating is just fast, and it is just high to heat up.Can provide under the prerequisite of enough electric currents in signal generation and amplifier 25, change the voltage height between first pole plate 22 and second pole plate 23 or change the temperature that its current work frequency can both effectively be controlled focus.The output frequency height of control signal generation and amplifier 25 output voltages height or control signal generation and amplifier 25 can both be realized adding hot lesion and be controlled at 41 ℃-44 ℃ purposes for the treatment of temperature.
Electric field of the present invention adds the hot lesion technical scheme three kinds of forms:
First kind of mode is that signal takes place and amplifier 25 is direct current (static) electric field modes.Described direct current signal takes place and amplifier 25 have two kinds of methods produce straight, flow voltages: a kind of method be exchange or the pulse small-signal after preposition amplification and power amplification, boost, obtain DC voltage after the rectification with transformator.Adjust the DC voltage height after the primary input just can be adjusted secondary commutation, just can change the size of current that flows through between first pole plate 22, second pole plate 23.Be between first pole plate 22, second pole plate 23 electric current on the focus and also change thereupon, the focus temperature just can be controlled on 41 ℃-44 ℃ the treatment temperature.Another kind method is that signal takes place and amplifier 25 is direct current amplifiers, and the output of direct current amplifier final stage is exactly direct current, and first pole plate 22, second pole plate 23 just directly are connected in two outfans of direct current final stage.
The second way is the impulse electric field mode, i.e. signal generation and amplifier 25 are pulseds.Adding on first pole plate 22, second pole plate 23 is pulse voltage.Controller 24 not only can controlling impulse voltage amplitude but also can control impuls width (dutycycle), control the average current size between first pole plate 22, second pole plate 23, control is in flows through the focus size of current between the two-plate, the focus temperature is controlled at 41 ℃-44 ℃.
The third mode is the AC field mode, and promptly signal takes place and amplifier 25 employing exchange waies.Added on first pole plate 22, second pole plate 23 is alternating voltage, and controller 24 not only can be controlled the interchange amplitude but also can control a-c cycle.The size of current between first pole plate 22, second pole plate 23 is flow through in control, and control is in the size of current of focus between the pole plate, makes the focus temperature be controlled at 41 ℃-44 ℃ treatment temperature.
Described signal takes place and amplifier 25 has two kinds of forms to produce the signal of telecommunication: a kind of is that local oscillator produces small-signal, through preposition amplification power amplification again; Also have, a kind of be external small-signal, through preposition amplification and power amplification.If external small-signal frequency just in time meets the requirements just directly to preamplifier; If external small-signal frequency is sent preamplifier behind the frequency division of higher position very much again; Will send preamplifier again after the frequency multiplication if external small-signal frequency is too low.
The controller 24 of described control electric field strong and weak is one to be taken place with signal and control circuit that amplifier 25 is inseparable, both can control automatically also and can artificial controlled system can also finish various control operations under the control of measurement and control maincenter 5.
As shown in Figure 2, described measurement and control maincenter 5 comprise pick off, signal amplification and processor, CPU, display.Described pick off the signal that collects send to signal amplifier and processor amplify with digital processing after, give CPU storage, calculating and logical judgment processing again, send display again and send control instruction, by the controller 24 concrete control tasks of carrying out to controller 24.Described measurement and control maincenter 5, the duty of tracking and monitoring focus temperature, the main life index of monitoring human and monitoring and control cancer treating instrument.The magnetic approach control principle is the same.
As shown in Figure 3, the present invention also comprises at least one pair of magnetic pole, and the direction of an electric field of described at least one pair of the polar magnetic direction and first pole plate 22, second pole plate 23 has angle.Described polar magnetic field makes that current path suffers restraints between first pole plate 22, second pole plate 23, or it is crooked that current path is produced.
Described first pole plate 22, second pole plate 23 are placed on the body foci both sides, between first pole plate 22, second pole plate 23, CURRENT DISTRIBUTION is dispersed, flowing through the affected area electric current might be littler than other places, affected area be warmed up to 41 ℃-44 ℃, the time, non-focal zone can be higher than the affected area temperature by the big local temperature of electric current; Also have a kind of situation to be because lesions position is difficult to be between first pole plate 22, second pole plate 23; There is a kind of situation will as much as possible avoid heart, spinal cord to be subjected to hyperpyrexia exactly again.The technical scheme that addresses these problems is that the electric current between first pole plate 22, second pole plate 23 is used restraint, and it is crooked to allow its current path produce, and makes the electric current that flows through focus more than other places as far as possible, reaches to add the purpose that hot lesion does not injure non-focal zone tissue again.Concrete scheme is: add one or more pairs of magnetic poles between first pole plate 22, second pole plate 23.
When the blood heat that might cause the confession brain rises to 40 ℃, can use low temperature installation cervical region, brain or relevant human body natural's passage are taked cooling measure.
