Abstract

The invention discloses a high-strength uniform-induction electric field generator based on an Archimedes spiral coil. According to the generator, a pulse current is generated through an LRC discharge circuit, the generated pulse current is introduced in the Archimedes spiral coil to generate a pulsed magnet field, and an induced electric field parallel to a coil plane surface is generated in the surface region of the coil. The induced electric field is high in amplitude value and uniform in distribution, and the coverage area of the induced electric field is the area, where the coil is positioned only. When the coil is close to tumor tissue of a body surface, the induced electric field concentrates on tissue in the coverage area of the coil, influences on surrounding normal tissue are avoided and the purpose of non-contact, non-invasion and accurate tumor treatment can be realized.

Description

technical field [0001] The invention relates to the field of biological electromagnetic technology, in particular to a high-intensity uniform induction electric field generator based on an Archimedes spiral coil. Background technique [0002] Malignant tumors have become the most important disease that threatens human life and health. However, the main treatment methods for tumors are still traditional surgery, radiotherapy and chemotherapy. Traditional treatment methods have relatively large side effects. Pulsed electric field treatment of tumors requires the insertion of electrode needles into the body, which poses trauma and biocompatibility issues to the human body. However, pulsed magnetic field treatment of tumors has the advantages of no contact, no pain, no harm, etc. The pulsed magnetic field generates induced electric field and induced current in biological tissue, which is the main mechanism of its biological effect. The force density of the interaction between t...
