摘　　要：射频消融(RFA)是目前广泛应用于肝肿瘤治疗的微创、有效方法 ,适用于不愿或不宜外科手术治疗患者。近20余年来RFA技术取得了长足的发展与进步。作为主要治疗工具,射频电极针对RFA疗效具有很大影响。该文就目前临床常用或处于研发阶段的射频电极针,如多针尖可扩展电极针、灌注电极针、内冷却电极针及双电极针等的特点进行总结,比较它们的优势与不足,展望进一步研究方向,以提高RFA治疗肝肿瘤效果。At present, radiofrequency ablation （RFA）, as a minimally-invasive and effective therapeutic means, is widely employed for the treatment of hepatic tumors. This technique is especially suitable for the patients with liver tumor who are unwilling to accept surgery or who cannot undergo surgery. In the past 20 years, great development and progress have been achieved in RFA technology. As a main therapeutic tool, the property of the radiofrequeney electrode needle has great influence on the curative effect. This paper aims to make a comprehensive summary about the radiofrequency electrode needles that are currently used in clinical practice or are still in the research and development stage, focusing on the following special radiofrequency electrode needles, including multiple-point expandable electrode needle, perfusion electrode needle, internal cooling electrode needle and bipolar electrode needle. The properties and distinguishing features of these radiofrequency electrode needles will be discussed, and their advantages and disadvantages will be compared. In order to improve the curative effect of RFA for hepatic tumors, further research is suggested. （J Intervent Radiol, 2017, 26 ： 466-470）
