Description
Technical Field
The utility model relates to an electric field produces device belongs to medical instrument technical field.
Background
Gliomas are a difficult to treat, fatal disease. According to the literature report, the annual incidence rate of the Chinese brain glioma is 3-6/10 ten thousand, and the annual death number reaches 3 ten thousand. At present, glioma treatment including means such as surgery, radiotherapy, chemotherapy, targeted therapy and the like cannot be completely treated due to extremely high recurrence rate of the glioma treatment due to continuous limitation. Tumor treatment electric fields (tumor treating fields) have a good effect on tumor treatment by interfering with the mitotic process of destroying cells. Currently, only NOVOTTF-100A medium frequency alternating electric field tumor treatment equipment developed by NoVokule (Novocure) Inc. is used in clinic globally.
The existing technology for treating tumors by integrating medium-frequency current electric fields is feasible for superficial tumors, but is not suitable for treating deep tumors. Because the epithelial cells have polarity, the epithelial tissues cover the surface of the body and the inner surfaces of various pipelines and cystic cavities in the body, and the epithelial tissue cells have better electric conductivity than other tissue cells. Meanwhile, the amplitude of unmodulated intermediate frequency current is unchanged, so that the medium frequency current is easily adapted to tumor cells, and the treatment effect is limited.
