TECHNICAL FIELD [0001] The present invention relates to a high frequency thermal cancer treatment apparatus using a local electrode,

The present invention relates to an apparatus for treating a high-frequency warm-blooded cancer using a local electrode.

One of the major factors in shortening the average life expectancy of humans in modern society is cancer. Surgical, chemotherapy, and radiation therapy are the main treatment methods for cancer treatment. One method is not a complete treatment method, and each treatment method has advantages and disadvantages.

Among them, surgical surgical therapy has a problem of causing damage to normal tissues when a large amount of cancer progresses. Also, when cancer is substantially progressed, chemotherapy resistance is raised, and especially in fragile patients with decreased immunity There is a problem to apply to.

Radiation therapy has been recently developed by the development of diagnostic imaging technology, such as CT and MRI, to improve the therapeutic effect of the cancer tissue. However, the side effects of destroying normal tissues around cancer tissues are not so serious.

High-frequency warm cancer therapy is a method of preventing cancer from spreading and metastasis by increasing the temperature of the affected part by directly or non-contactally applying an alternating current of 100 Hz or more to the affected part of the patient. As compared with surgery, chemotherapy, Which is widely used in recent years.

Thus, it has become necessary to develop a high-frequency thermal cancer treatment apparatus using a local electrode which can effectively and efficiently treat hyperthermia in all the specific regions.

In the present invention, the shape of the electrode plate of the high-frequency radiator is variously shaped so as to localize the shape of the high-frequency beam irradiated, and the high-frequency beams having various directions are mixed to irradiate localized or three- It is an object of the present invention to provide a device for treating a hyperthermia cancer using a local electrode capable of effectively inducing necrosis of cancer tissue caused by deep heat without damaging the tissue as much as possible.

The present invention also relates to a device for treating a hyperthermia cancer using a local electrode capable of minimizing the time taken to heat up to a temperature of 42 캜 for inducing necrosis of cancer tissue by deep heat by concentrating the high- The purpose is to provide.
