FLEXIBLE ABLATION MECHANISM

WIPO Patent Application WO/2017/039390

A1

The present invention relates to a flexible ablation mechanism and, more particularly, to an ablation mechanism configured to supply a high-frequency current to an ablation tip, which is drawn out of an electrode unit, thereby ablating a lesion by high-frequency waves, wherein, as the ablation tip is drawn out of the electrode unit during use by a drawing in/out means in a variable manner, the same is drawn out while maintaining a shape that gradually bends more in a stepwise manner, and, when drawn into the electrode unit by the drawing in/out means after use, the ablation tip is drawn therein while maintaining a shape that becomes closer to a straight line from the bent shape in reverse. The present invention is advantageous in that the ablation mechanism can be inserted into the position of the lesion, which is to be ablated, with no difficulty from the beginning, and, even when the ablation tip needs to pass through a curved passage to reach the position of the lesion, the ablation tip, which is drawn out while bending, can pass through the same with no problem.
