Ablation device and radiofrequency ablation equipment

Abstract

The invention provides an ablation device and radiofrequency ablation equipment. The ablation device comprises a first electrode assembly with a first electrode tip, and the first electrode tip comprises a first protective sheath and a plurality of first electrodes arranged on the first protective sheath; the first protective sheath is strip-shaped, and the plurality of first electrodes are arranged at intervals along the extension direction of the first protective sheath; in other words, the multiple first electrodes act on the corresponding tissue at the same time to form a complete ablation line, so that the good ablation effect is achieved, and the ablation efficiency is improved; therefore, by means of the ablation device, 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 instruments, in particular, to an ablation device and radiofrequency ablation equipment. 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 complete ablation l...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide an ablation device and radio frequency ablation equipment to solve the problems of large surgical ablation trauma, slow postoperative recovery, limited angle during use, and inconvenient operation; solve the problem of constant ablation energy in current internal medicine intervention , unable to adjust the output power according to the ablation effect in a timely manner, resulting in the problem of overheating or impermeability; solve the problem that the current medical and surgical ablation equipment requires additional equipment for mapping after ablation, and the operation is cumbersome

[0006] Furthermore, the first protective sheath is made of flexible material and can be rotated at any angle, which solves the problem of limited angles of current surgical ablation instruments
