Tumor electric field treatment system and electrode plate thereof

Abstract

The invention provides a tumor electric field treatment system and an electrode plate thereof, which are used for performing electric field treatment on a tumor part of a trunk of a patient during tumor electric field treatment, and comprise a plurality of electrode units arranged in an array, a plurality of connecting parts for connecting two adjacent electrode units, and a wire electrically connected with the plurality of electrode units, the number of the electrode units is at least ten, the electrode units are distributed in a matrix with at least three rows and four columns, each electrode unit is connected with at least two adjacent electrode units, and at least two adjacent electrode units in the plurality of electrode units are arranged in a spaced row or spaced column shape. According to the electrode slice, the alternating electric field is applied to the tumor part of a patient through the at least ten electrode units for tumor treatment, the situation that the treatment effect is affected due to insufficient electric field treatment caused by the differences of tumor sizes, parts and positions can be avoided, the coverage area of the electrode slice is increased, the intensity of the electric field applied to the tumor part is enhanced, and the treatment effect is improved.

Description

technical field [0001] The invention relates to a tumor electric field treatment system and an electrode sheet thereof, belonging to the technical field of medical devices. Background technique [0002] At present, tumor treatment methods mainly include surgery, radiotherapy, chemotherapy, etc., but there are corresponding shortcomings. For example, radiotherapy and chemotherapy will produce side effects and kill normal cells. The use of electric fields to treat tumors is also one of the frontiers of current research and development. Tumor Treating Fields (Tumor Treating Fields, referred to as TTF) is a low-intensity, medium-frequency alternating electric field applied to cancer cells, thereby interfering with the process of cancer cell mitosis, inhibiting Cancer cell mitosis, induce cancer cell apoptosis, and thus play a therapeutic effect. Studies have shown that electric field therapy is effective in the treatment of glioblastoma, non-small cell lung cancer, malignant pl...

AI Technical Summary

Problems solved by technology

Due to the difference in the body of the patient, the tumor location, tumor location, and tumor size are different. When using the existing electrode sheet disclosed in the Chinese Invention Patent Publication No. 112717272 for treatment, there will be a problem of applying the electrode sheet to the tumor site for treatment. Insufficient electric field strength, or the electric field does not cover part of the tumor, which affects the treatment effect
