Summary of the invention
The present invention is directed to above-mentioned technological deficiency, utilize the electricity physical characteristic of inductance and diode, invented the oncotherapy technical equipment IRE cliffy summit flat-top cancer treating instrument of new simple and easy pulse generator, make porch steeper, top is more flat, this pulse is better to the therapeutic effect of tumor, more can in the situation that do not injure the normal health cell, effectively to kill malignant cell be cancerous cell or induce its apoptosis.
Technical solution of the present invention is that this therapeutic instrument mainly comprises: power supply, commutator, pulse generator, the electrode with endoscope, oscillograph, medicine CT, B ultrasonic and endoscope, computer and related accessory.
The feature of pulse generator is: comprise two unit that structure is identical, each unit comprises inductance or inducer, electric capacity or capacitor or impulse capacitor, diode and gate-controlled switch or derailing switch.The circuit of each unit is on connected mode: after the negative pole of commutator out-put supply and inductance or electrical equipment and diode are in parallel, one tunnel is in parallel with negative pole and the electrode of electric capacity or capacitor through inductance or inducer, is connected with switch or derailing switch first end after a road is connected with electrode.The second end of switch or derailing switch is connected with the positive pole of commutator out-put supply; It is the second end that an end of inductance is connected to gate-controlled switch, the other end of inductance connects the positive pole of diode, the negative pole of diode connects an end of electric capacity, the other end of electric capacity connects can be by the second end of switch, the be connected positive pole of rear input power as this pulse generator of connection one end of each inductance in two elementary cells, an end separately of the electric capacity in the be connected negative pole of rear input power as this pulse generator of the first end of the gate-controlled switch in two elementary cells, two elementary cells is respectively as outfan and be connected with electrode respectively.
The quantity of gate-controlled switch or derailing switch is included as one or more than two of serial or parallel connection.
Gate-controlled switch maybe can comprise by the device of derailing switch metal-oxide-semiconductor, IGBT pipe, GTO pipe, GTR pipe.
Usefulness of the present invention: can obtain by control the precipitous pulse of flat-top of needed different peak values, the pulse that obtains voltage can exceed input direct voltage, also can be lower than input direct voltage.

The specific embodiment
Explain in conjunction with above-mentioned figure, Fig. 6 is schematic diagram of the present invention, comprise casing 11, pulse generator 12, ballast switch or derailing switch 13, electrode 21, oscillograph and electrode connecting line 22, pulse generator input and the electrode connecting line 23 of the gate-controlled switch M1 button keys 15 of commutator 14, pulse generator, the gate-controlled switch M2 button 16 of pulse generator, on and off switch or beginning device 17, starting switch 18, computer and liquid crystal display 19 thereof, oscillograph 20, load load.Casing 11 is the supporting body of upper other each components and parts of mistake, starting switch is connected with mains supply with on and off switch or derailing switch 17 1 ends, one end is connected with the discrepancy of commutator 14, and the outfan of commutator is connected with the input of pulse generator after being connected with starting switch, starting switch and.Computer or its display are connected with on and off switch, ballast switch, starting switch, medicine CT, B ultrasonic, oscillograph one end respectively, and the oscillograph other end is connected with load loadr electrode.During use, after switching on power, start on and off switch, the liquid crystal display display power supply is connected, and mains supply enters commutator, and to advance rectification be unidirectional current, starts rectifier switch, unidirectional current arrives starting switch, opens and starts beginning, and DC current and pulse generator are connected.Press the gate-controlled switch M2 button 16 of the gate-controlled switch M1 button keys 15 of pulse generator or pulse generator and start or close gate-controlled switch or derailing switch M1 or the M2 of pulse generator, the pulse current of pulse generator generation arrives load electrode, the precipitous square-topped pulse that electrode sends, can the kill tumor cell or the apoptosis of inducing tumor cell.Whole process under the imaging guiding of B ultrasonic, medicine CT instrument and endoscope, can be treated accurately to tumor locus.
As depicted in figs. 1 and 2, the present invention includes the identical elementary cell of structure, each unit comprises inductance, electric capacity, diode and gate-controlled switch.It is the second end that an end of inductance is connected to gate-controlled switch, the other end of inductance connects the positive pole of diode, the negative pole of diode connects an end of electric capacity, the other end of electric capacity connects can be by the second end of switch, the be connected positive pole of rear input power as this pulse generator of connection one end of each inductance in two elementary cells, an end separately of the electric capacity in the be connected negative pole of rear input power as this pulse generator of the first end of the gate-controlled switch in two elementary cells, two elementary cells is respectively as outfan and be connected with electrode respectively.Electrode is the electrode of load load.Gate-controlled switch can be one or in series or in parallel with each other more than two and two.Inductance comprises inducer, coupling inductance.
As shown in Figure 3, M1 drives ripple 1, and M2 drives ripple 2, M1 drain-source blood pressure lowering 3, M2 drain-source blood pressure lowering 4, output voltage 5.
Pulse generator charging and discharging process as shown in Figure 4 and Figure 5, after gate-controlled switch or gate-controlled switch device M1 or the driven admittance of M2, inductance (or coupling inductance, inducer) L1 or L2 or magnetize; After M1 or M2 disconnection, because inductive current can not change suddenly, capacitor C 1 or C2 can be recharged and cause capacitor C 1 or C2 voltage to raise; When M2 disconnects and during the M1 admittance, afterflow diode D2 conducting, the voltage of C2 is added on load load and electrode or electrode by M2, obtains a pulse voltage on load load and electrode or electrode; On the contrary, when M1O disconnects and during the M2 admittance, afterflow diode D1 conducting, the voltage of C1 is loaded on load load and electrode or electrode by M1, on load load and electrode or electrode just before a reverse impulse voltage.Leakage inductance or the mutual inductance function of current due to inductance, diode D1 or the quick admittance of D2 meeting, when inductance (mutual inductance or leakage inductance) electric current reaches zero, the backward voltage that D1 or D2 bear C1 or C2 can stop fast, like this time of the rise and fall of the pulse voltage on load load and electrode or electrode very of short duration, the pulse voltage that height of formation is precipitous.Because the voltage pulsation of capacitor C 1 or C2 is very small, the fluctuation of the flat-top of the pulse voltage of load load and electrode or electrode is also very small.
