Description

Magnetic cyclotron electrochemical tumor therapy device

The invention relates to an electrochemical treatment device used for treating tumors, which belongs to medical equipment.

Direct current electrochemotherapy was pioneered by radiation medicine experts in Sweden. It inserts a pair or a group of electrodes on the tumor tissue and passes a direct current, so that a series of bioelectrical processes such as electrolysis, electrophoresis, and electroosmosis occur in the tumor tissue around the electrodes. Chemical changes make it necrotic to achieve the effect of tumor suppression. The commonly used device is composed of a control panel, a power supply, and electrodes, and the voltage, current, and treatment time can be preset. This therapy has the advantages of less trauma, safety, simplicity and easy operation. However, due to the one-dimensional swimming of charged particles between the electrodes, a fixed channel is formed between them, and the therapeutic substance cannot be uniformly distributed in the tumor tissue in time. As a result, the treatment area only forms a columnar killing effect around the needle, which affects the treatment effect.

The object of the present invention is to provide a magnetic cyclotron electrochemical tumor treatment device that adds magnetic field, high-voltage pulse electric field and microwave around the tumor.

The task of the present invention is achieved through the following technical proposals: the DC magnetic field excitation power supply and the alternating magnetic field excitation power supply are connected to the electromagnet coil, the electromagnet coil is sleeved on the electromagnet core, the alternating power supply, the electrochemotherapy power supply The high-voltage pulse power supply is connected to at least one electrode and the center electrode, and the radio frequency power supply is connected to the center electrode.

The present invention improves the existing electrochemical therapeutic apparatus, increases the effects of DC and AC magnetic fields, pulsed electric fields and microwaves on tumors, and makes the ions and charged particles swimming between the electrodes in the tumor tissue move vertically to the magnetic field at the same time. In the direction of the center electrode as the axis, it makes a gyratory motion in the entire tumor tissue, and the charged particles attract different amounts of water and other polar molecules around it, and drive the electrochemical treatment substance to make a gyratory motion together, overcoming the Disadvantages of Electrochemotherapy. The alternating magnetic field and the alternating electric field between the electrodes can strengthen the magnetic cyclotron according to certain requirements, which can not only enhance the spatiotemporal regulation of the treatment but also improve the utilization rate of the treatment substance and the effectiveness of the treatment. The pulsed electric field and microwave electromagnetic field added as required also further enhance the curative effect.
