ASYMMETRIC BIPOLAR ELECTRODE NEEDLE FOR HIGH-FREQUENCY HEAT THERAPY
Document Type and Number:
WIPO Patent Application WO/2012/153927
Kind Code:
A3
Abstract:
The present invention relates to an electrode needle for high-frequency heat therapy, which necrotizes a lesion site, such as cancer tissue in a bodily organ, by heating the lesion site, by means of high-frequency waves, and cauterizing the same. One embodiment of the present invention provides an asymmetric bipolar electrode needle for high-frequency heat therapy, the needle being formed comprising two or more conductive portions which are separated from one another by at least one insulating portion, wherein the two or more conductive portions have an asymmetric structure in which one of the conductive portions is longer than the other, and electrodes are arranged in a bipolar manner, enabling the asymmetric bipolar electrode needle for high-frequency heat therapy to cauterize a large tissue area; and the area which is to be cauterized can be selectively adjusted.
