Radiofrequency heating probe device and radiofrequency ablation device

Abstract

Embodiments of the invention provide a radio frequency heating probe device and a radio frequency ablation device, the radio frequency heating probe device comprises: a probe head, a liquid metal, a flexible probe conduit, a curvature adjusting member, a heat exchange member and a pumping member, the liquid metal is driven by the pumping member to circulate through the loop composed of the flexible liquid inlet conduit, the probe head, the flexible liquid outlet conduit and the heat exchange member, and the curvature adjusting member is arranged in the flexible probe conduit and is used for adjusting the curvature of the flexible probe conduit. The radiofrequency heating probe device and the radiofrequency ablation device provided by the embodiments of the invention adopt a flexible and foldable probe tube structure and control the folding degree of the probe tube by changing the temperature of the resistance wire, so that the radiofrequency heating probe device and the radiofrequencyablation device can be better adapted to the cardiac environment of a human body; and, through the liquid metal circulating in the conduit, the probe head temperature is effectively prevented from being too high, and the corrosion of the traditional cooling medium to the probe head can be avoided.

Description

Technical field [0001] The embodiment of the present invention relates to the field of electrical ablation medical equipment, and more specifically, to a radio frequency heating probe device and radio frequency ablation equipment. Background technique [0002] Atrial fibrillation is a common tachyarrhythmia, and its incidence gradually increases with age. In the treatment of atrial fibrillation, medication is a common treatment method, which can relieve the symptoms to a certain extent and avoid the pain of the patient's operation. But in many cases, the effect of drug treatment is not ideal. And some patients with atrial fibrillation cannot be relieved by medication for various reasons. With the development of science and technology, non-drug treatment methods have gradually become the focus of attention. Currently, among the non-pharmacological methods for the treatment of atrial fibrillation, the most commonly used method is radiofrequency catheter ablation, which has becom...
