Abstract

The invention discloses a high-intensity uniform induction electric field generator based on an Archimedes spiral coil. The generator generates a pulse current through an LRC discharge circuit, and the generated pulse current flows into the Archimedes spiral coil to generate a pulse magnetic field. The surface area of ​​the coil produces an induced electric field parallel to the plane of the coil. The induced electric field has high amplitude, uniform distribution, and covers only the area where the coil is located. When the coil is close to the tumor tissue on the body surface, the induced electric field concentrates on the tissue covered by the coil without affecting the surrounding normal tissue, and can achieve the purpose of non-contact, non-invasive and precise tumor treatment.

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...
