摘要

在过去的二十年中,射频消融术(RFA)被认为是治疗原发性和继发性恶性肿瘤的一种很有前途的医疗方法。然而,目前开发的用于此类治疗的针基电极并不适用于位于食管、结肠、胆管等中空器官的肿瘤热消融。本文提出了一种管状电极溶液。数值和实验分析进行表征病变的体积。结果表明,这种电极是一种可行的解决方案,数值模拟可以为一定精度的RFA工艺规划提供工具。

A Tubular Electrode for Radiofrequency Ablation Therapy
In the last two decades radiofrequency ablation (RFA) has been considered a promising medical procedure for the treatment of primary and secondary malignancies. However, the needle-based electrodes so far developed for this kind of treatment are not suitable for the thermal ablation of tumors located in hollow organs like esophagus, colon or bile duct. In this work a tubular electrode solution is presented. Numerical and experimental analyses were performed to characterize the volume of the lesion induced. Results show that this kind of electrode is a feasible solution and numerical simulation might provide a tool for planning RFA procedure with some accuracy.
