Objective: Pino et al reported that strip lesions were produced when the distance between two probe was 2 to 6mm, and it resulted in unipolar lesions when they were spaced more than 6 mm apart. However, in clinical studies and some other reports, bipolar radiofrequency treatment was also effective when the distance was 10mm. Therefore, we duplicated Pino et al's experimente to study the lesion morphology when the distance of two radiofrequency cannulae was arranged between 2 and 10mm.

目的： Pino等人的研究发现双针间距在2-6mm之间时双电极之间可形成带状毁损，而8mm、10mm间距时双电极针成为独立的电极毁损，而在临床研究及某些文献报道中可以看到双电极间距在10mm时治疗同样有效，因此本文重复Pino等人的实验，研究双针电极间距在2-10mm时双针射频毁损形态。
