摘要
腰椎间盘突出症是临床上的常见病和多发病。射频消融技术近十年来发展迅速,第一代射频电极为实心金属单极电极。由于电极周围碳化增加阻抗,使电流减小,阻止了对组织的进一步摧毁,于是出现了增加电极针的方法,由两个电极组成双极电极针,无负电极板。消融时电流由正电极针流向负电极针,大大减少了负电极板对皮肤的烧伤,是一种实用、微创、安全、可重复、不影响腰椎稳定性且具有发展前途的新技术。
Lumbar disc herniation is a common and frequently-occurring disease in clinical.Radiofrequency ablation in the past decade has developed rapidly and achieved good results.The first generation of the RF electrode is unipolar electrode of the solid metal.Carbonation around the electrode increases the impedance,which reduces the current to prevent the further destruction of the tissue,so increasing the electrode needle from bipolar electrode needle to two-electrode,and non-negative electrode plate,has occurred.During ablation the current flows from the positive electrode needle to the negative electrode needle,greatly reducing the negative electrode plate burns on the skin,which is a practical,minimally invasive,safe,reusable,promising new technology with no influence on lumbar stability.
