Title:
NON-INVASIVE RADIO-FREQUENCY ABLATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/042111
Kind Code:
A1
Abstract:
Disclosed is a non-invasive radio-frequency ablation system, comprising an ablation apparatus (1). The ablation apparatus (1) comprises: a substrate (2) having a first surface (21); a first electrode (3) arranged on the first surface (21); a second electrode (4) arranged on the first surface (21) and adjacent to the first electrode (3); and a movement unit (5) electrically connected to the second electrode (4), the movement unit (5) being used for moving the second electrode (4) to adjust the distance between the second electrode (4) and the first electrode (3). The non-invasive radio-frequency ablation system further comprises a radio frequency generator connected to the ablation apparatus (1), the radio frequency generator being used for providing a radio frequency current to the first electrode (3) and the second electrode (4). The method for using the ablation apparatus (1) involves: bringing the first electrode (3) and the second electrode (4) into contact with a third surface (11) of a subject (10) needing to be treated, and applying a radio frequency current to the first electrode (3) and the second electrode (4) so as to execute a treatment process. The depth and area of treatment are adjusted by changing the distance between the first electrode (3) and the second electrode (4).
