20G 22G MDR CE Disposable Radiofrequency Needle Medical RF Needle
Reliable energy delivery for C-arm and fluoroscopy-guided radiofrequency ablation.
Designed for interventional pain management procedures including facet joint denervation, medial branch neurotomy, and peripheral nerve ablation.
What is a Radiofrequency (RF) Needle?
A radiofrequency (RF) needle is a sterile disposable electrode used in minimally invasive RF ablation procedures. It delivers controlled RF energy from a generator to targeted tissue, creating thermal lesions for pain management, nerve ablation, or soft tissue coagulation.
The needle is designed to work as a precise energy delivery interface between the RF generator and human tissue, ensuring controlled lesion formation with minimal collateral damage.
How RF Needle Works in Tissue
When connected to a radiofrequency generator, the RF needle delivers alternating current into biological tissue. The electrical resistance of the tissue converts this energy into localized heat, forming a controlled lesion at the target nerve or tissue site.
This process allows clinicians to interrupt pain signal transmission while minimizing damage to surrounding healthy structures.
