RF Ablation Needle

Product Overview Disposable Radiofrequency Ablation Needle is a sterile, single-use medical electrode device, specially designed for minimally invasive radiofrequency ablation therapy. It is widely applied in tumor ablation, pain management, neurological intervention and orthopedic minimally invasive surgery. Adopting high-precision manufacturing technology, the needle delivers stable radiofrequency output, accurate lesion positioning and safe minimally invasive treatment, effectively avoiding cross-infection caused by repeated use of traditional electrodes.
