Problems solved by technology

Although pulsed electrochemotherapy has achieved remarkable results in the clinical treatment of tumors, it only plays an auxiliary role in enhancing the efficacy of chemotherapy drugs, and cannot fundamentally avoid the side effects of chemotherapy drugs on the patient's body.

Abstract

The present invention is tumor treating steep pulse equipment and process, and belongs to the field of tumor treating technology. The tumor treating steep pulse equipment includes one steep pulse generating, measuring and controlling system, one computer system, one power source system, and one control console. The tumor treating steep pulse equipment with tumor treating electrodes is used for program tumor treatment, and ns level steep pulse is applied to the tumor tissue, so as to destroy and kill tumor cell irreversibly through electric shock. The present invention has high treatment effect, no side effect caused by chemotherapeutic medicine and simple operation, and may be used widely for the tumor treatment of human body and animal.

Description

technical field [0001] The invention belongs to the technical field of tumor treatment, and in particular relates to a device for treating tumors and a method thereof. Background technique [0002] The methods currently used to treat tumors mainly include surgical resection, radiation therapy, chemotherapy, and hyperthermia. Due to the limitation of indications, contraindications, side effects and other factors, the curative effect of these methods on tumors is still not ideal. [0003] Pulse electrochemical therapy is a new technology for tumor treatment developed in the past 30 years, which was pioneered by Japanese scholar M.Okino in 1987. The treatment method is to give intravenous administration or intramuscular injection around the tumor tissue, give a certain dose of chemotherapy drugs (such as bleysin, cisplatin, etc.) Dose of square wave electrical pulse (peak value 1-2kV / cm, pulse width 100μs, frequency 1-4Hz, number of pulses 4-10) adjuvant therapy. Under norma...
