电极组件、消融装置和射频消融设备Electrode assemblies, ablation devices, and radiofrequency ablation devices

技术领域technical field

本发明涉及医疗器械领域，具体而言，涉及一种电极组件、消融装置和射频消融设备。The present invention relates to the field of medical devices, in particular, to an electrode assembly, an ablation device and a radiofrequency ablation device.

背景技术Background technique

消融是治疗房颤的常见措施，其原理是在心脏组织创建一条或多条消融线，引起组织坏死，切断不正常的电信号传导，用于房颤的治疗。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.

当前的消融治疗分为外科消融和内科介入消融，外科消融的特点是疗效优，术后复发率低，但是其显而易见的缺点是创伤较大，术后恢复慢。内科的介入式消融因为创伤小、恢复快受到越来越多患者的青睐，但是内科消融是点状消融，其最大的弊端便是很难形成一条完整的消融线；且消融时是单侧贴壁式工作，消融深度有限，很难保证组织由内至外完全脱水、变性，手术中消融功率小时消融不彻底，而功率大了又不易掌控，有消融过度组织坏死甚至烧穿、烧漏现象，故内科介入式消融的成功率较外科低好多。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 line; Wall work, the ablation depth is limited, and it is difficult to ensure complete dehydration and degeneration of the tissue from the inside to the outside. During the operation, the ablation power is small and the ablation is not complete, but the power is high and it is difficult to control. There are excessive ablation tissue necrosis or even burning through and burning leakage. Therefore, the success rate of medical interventional ablation is much lower than that of surgery.
