Title:
ELECTRODE ASSEMBLY, ABLATION DEVICE AND RADIOFREQUENCY ABLATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/148159
Kind Code:
A1
Abstract:
An electrode assembly, an ablation device and a radiofrequency ablation apparatus. The electrode assembly comprises a first electrode tip (110), wherein the first electrode tip (110) comprises a first protective sheath (113), and a first electrode (111) and a filling member (116), which are arranged inside the first protective sheath (113), the first electrode (111) is pressed by the filling member (116) so as to move the first electrode (111) towards tissue (340) to be ablated, then the first electrode (111) can be attached to an inner wall of the first protective sheath (113), and an outer wall of the first protective sheath (113) at the corresponding position is attached to the corresponding tissue (340) to be ablated, such that it is guaranteed that the first electrode (111) can successfully act on the corresponding tissue (340) to be ablated, and an ablation effect is guaranteed. By means of a first electrode (111), the problems in the prior art of an ablation device not being firmly attached to tissue (340) to be ablated, the tissue (340) to be ablated being prone to disengaging, and an ablation effect not being ideal can be solved.
