Abstract

The invention relates to a high-voltage pulse electric field treatment device based on multi-needle electrodes. Existing treatment devices all cause harm to the body to a certain extent, and have relatively large side effects. The invention includes a plurality of needle-shaped electrodes, an insulating sleeve, a connector, a high-voltage pulse generator and a high-voltage pulse controller. One of the multiple needle-shaped electrodes is connected to the negative pole of the high-voltage pulse generator, and the other single needle-shaped electrodes are connected to the negative pole of the high-voltage pulse generator through a connector. The single needle-shaped electrode includes a needle-shaped metal part and an insulating varnish coating. The upper part of the needle-shaped metal part is covered with an insulating varnish coating; an insulating sleeve is placed outside the insulating varnish coating; Material. The invention has the advantages of simple structure, low cost and convenient manufacture and maintenance.

Description

technical field [0001] The invention belongs to the technical field of medical machinery, and relates to a high-voltage pulse electric field treatment device based on multi-needle electrodes. Background technique [0002] At present, the main treatment methods for the treatment of the diseased part of the patient (taking tumor as an example) are as follows: 1. Surgical treatment, which adopts the method of surgical resection of the tumor. The effect is better in the early stage of treatment, but the effect in the middle and late stage is not as good as that in the early stage. The second is radiation therapy, which uses isotope decay and radiation therapy produced by accelerators, but radiation therapy itself will bring some short-term or long-term side effects. Three, chemotherapy. Chemotherapy is the main means of using chemical antineoplastic drugs to treat malignant tumors, but the side effects of chemotherapy drugs are relatively large. Fourth, interventional therapy r...
