Abstract

The invention discloses a telescopic annular saline infusion radio frequency ablation device which is characterized in that a plurality of radio frequency ablation electrodes are arranged on a radio frequency ablation electrode ring, a plurality of jet holes are formed in each radio frequency ablation electrode, and the radio frequency ablation electrodes are controlled to perform ablation treatment through a catheter handle. And the radiofrequency ablation electrode is cooled by controlling the jet holes to jet the cooling saline water, so efficient ablation treatment is realized, the operation time is shortened, and the problems of point-by-point ablation, low efficiency and long operation process time in the prior art are solved.

Description

Technical field[0001]The invention relates to the technical field of medical devices, and in particular to a telescopic ring-shaped saline perfusion radio frequency ablation device.Background technique[0002]The existing electrophysiological radiofrequency ablation electrode ring is represented by Johnson & Johnson’s Smart Touch saline perfusion radiofrequency ablation electrode ring. The core design is to cooperate with a three-dimensional mapping system to complete the entire surgical process with the point-by-point linear ablation of the large-head electrode. However, the saline perfusion radiofrequency ablation electrode ring is limited by the shape and structure of a single large-head electrode. When performing operations such as atrial fibrillation ring pulmonary vein isolation ablation, it can only be completed point by point, which is very inefficient and the operation process is very long.Summary of the invention[0003]The invention provides a retractable annular saline perfu...
