Abstract

The invention provides an electrode assembly, an ablation device and radiofrequency ablation equipment, the electrode assembly comprises an electrode tip, the electrode tip comprises a protective sheath, an electrode and a first magnetic piece, and the electrode is arranged in the protective sheath; the first magnetic piece is arranged in the protective sheath so as to position the electrode tip through the first magnetic piece; wherein the protective sheath is provided with a first avoiding opening used for avoiding the electrode and a second avoiding opening used for avoiding the first magnetic piece, a part of structure of the electrode extends out of the protective sheath from the first avoiding opening, and a part of structure of the first magnetic piece extends out of the protective sheath from the second avoiding opening; by using the electrode assembly, the problem that the ablation effect of an ablation device in the prior art is not ideal can be solved.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular, to an electrode assembly, an ablation device and a radiofrequency ablation device. Background technique [0002] Ablation is a common measure for the treatment of atrial fibrillation. The principle is to create one or more ablation lines in the heart tissue, causing tissue necrosis and cutting off abnormal electrical signal conduction for the treatment of atrial fibrillation. [0003] The current ablation treatment is divided into surgical ablation and medical interventional ablation. Surgical ablation is characterized by excellent curative effect and low postoperative recurrence rate, but its obvious shortcomings are large trauma and slow postoperative recovery. Medical interventional ablation is favored by more and more patients because of its small trauma and fast recovery, but medical ablation is point ablation, and its biggest drawback is that it is difficult to form a c...
