Abstract
The present invention relates to an electrochemistry therapeutic device for treating a tumour, which belongs to a medical appliance. The present invention is characterized in that a direct current magnetic field excitation power source, an alternating magnetic field excitation power source are connected with an electromagnet coil sheathed on an electromagnet iron core; an electric chemotherapeutic power source, a high-voltage pulse power source and an alternating power source are connected with at least two electrodes and a central electrode; a radio-frequency power source is connected with the central electrode. Because a direct current magnetic field, an alternate current magnetic field, a pulse electric field and microwaves are added to act on a tumour, the biological chemistry molecules of a tumour tissue move in a convolution mode in the whole tumour tissue to overcome columnar lethal effect and enhance curative effect.
Description
The present invention relates to treat the used electrochemical therapeutic therapeutic apparatus of tumor and belong to medical apparatus and instruments.
The unidirectional current chemotherapy is that the radiological medicine expert of Sweden starts, it is to insert a pair of or one group of electrode on tumor tissues, pass to DC current, thereby a series of bio electrochemistry such as tumor tissues generation electrolysis around the electrode, electrophoresis, electric osmose changes, and makes it downright bad and reach the effect that presses down tumor.Normally used device is made up of panel, power supply, electrode needle, but preset voltage, electric current, treatment time.This therapy has little, safe, simple, the maneuverable advantage of wound.But because charged particle is in the swimming of electrode catch cropping straight line, form fixed passage betwixt, therapeutant uniform distribution in time in tumor tissues.Cause area for treatment only be centered around pin around form the column lethal effect, influence therapeutic effect.
The objective of the invention is to provide a kind of magnetogyric electrochemical apparatus for treating tumor that in being subjected to curing oncoma, increases magnetic field, high-pressure pulse electric and microwave.
Task of the present invention is accomplished by following technical scheme: D.C. magnetic field field power supply, alternating magnetic field field power supply are received on the electromagnet coil, and electromagnet coil is enclosed within on the electromagnet core.The utmost point that electrification is treated power supply, high-voltage pulse power source links to each other with central electrode with radio frequency (microwave) power supply through connecting line, and another utmost point links to each other with plural at least peripheral electrode.
The present invention improves existing electrochemical therapeutical instrument, has increased direct current and AC magnetic field, impulse electric field and microwave to function of tumor.When using D.C. magnetic field, adopt the unidirectional current chemotherapy.The central electrode pin that inserts tumor tissues this moment is negative pole (an also positive level), the peripheral electrode pin that inserts tumor tissues is anodal (or negative pole), when magnetic direction and direction of an electric field are vertical mutually, making in the tumor tissues at the ion of swimming between electrode and other charged particle is the axle center with the central electrode under the effect at Lorentz force again simultaneously, does circumnutation in whole tumor tissues.Charged particle has attracted water and other polar molecule of varying number around it, and has driven the electrochemotherapy material and do circumnutation together, makes the therapeutical effect can be synchronous in time as much as possible, spatially carries out equably.Thereby overcome the weak point of electrochemical treatment.Can strengthen the magnetic circumnutation by alternating magnetic field and interelectrode alternating electric field that certain requirement alternately adds.The particle of doing circumnutation in tumor tissues is distributed in respectively in intercellular fluid and the intracellular fluid, and the former will pass intercellular slit, and the latter also will pass cell membrane, thereby produces the resistance of motion in various degree.According to the Lorentz force law, electric-field strength, when charged grain power movement velocity is big, Lorentz force is just big under same magnetic field intensity, can overcome certain resistance.But during electric-field strength, cell reaction in the tumor tissues is accelerated, and product (tumor cell kill and wound material) increases, and can not in time borrow circumnutation uniform distribution in tumor tissues.For improving this situation, electric field and magnetic field synchronously change over alternating field frequently, make the direction of circumnutation constant, and cell reaction slows down or stop to carry out, and are the accumulation of scalable electrode reaction product around electrode needle like this.This can not only strengthen the space-time regulating action of treatment, and can improve the utilization rate of therapeutant and the effectiveness of treatment.Impulse electric field of Jia Ruing and microwave electromagnetic field also all further heighten the effect of a treatment on request.
