By human body, forming radio frequency puncture needle points stimulates loop structure；
3) needle stand activity noncontinuous electrode joint is disconnected, minus plate is removed；
4) by the satisfactory pin withdraw of the needle vertically of radio frequency puncture needle, catheter needle is longitudinally inserted into, forms injection-type radio-frequency electrode pin, fixed pin
Body position is constant；
5) catheter needle is withdrawn from, again insertable into nook closing member, the outer pin of condensation radio frequency needle, after composition puncture needle assembly, while exiting combination
Pin；
6) using step 2), 4) formed structures and methods peripheral nerve or intraspinal tube neural stimulation therapy and god are carried out to human body
Through Block For Treating or nerve and tumour ablation.
