| 摘要 |
<p>The present invention relates to an overlapping bipolar electrode for a high-frequency heat treatment, comprising: a cylindrical body (11); an active electrode assembly (13), which is wound around a plurality of times from a front end toward a rear end of the external circumferential surface of the body (11) and which is connected to a terminal on one side of a high-frequency wave generator; and a passive electrode assembly (15), which is wound around a plurality of times from the front end toward the rear end of the external circumferential surface of the body (11) in between the active electrode (13) and which is connected to a terminal on the other side of the high-frequency wave generator, thereby matching the shape of the range of heat generation, which is due to emitting high-frequency energy that is generated from between the active electrode assembly and the passive electrode assembly that are adjacent and correspond to each other, to the shape of a lesion area on a tubular tissue, such as blood vessels, so that damage to surrounding normal tissue is minimized when cauterizing, and thus significantly increasing heat treatment efficiency by means of electrodes.</p> |
