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 arranged in the protective sheath, a suction positioning piece arranged on the protective sheath and an extrusion positioning piece at least partially located on the outer side of the protective sheath, the protective sheath is positioned on the to-be-ablated tissue under the action of the suction positioning piece; at least part of the extrusion positioning piece is arranged in an expandable manner, so that an extrusion effect is formed on the protective sheath when the extrusion positioning piece is expanded, and the protective sheath is attached to the corresponding to-be-ablated tissue under the extrusion effect, that is, the protective sheath is extruded on the to-be-ablated part; therefore, the electrode in the protective sheath better acts on a corresponding part to be ablated, and the ablation effect is ensured; therefore, 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 quick recovery, but medical ablation is point ablation, and its biggest drawback is that it is difficult to form a ...
