Radiofrequency needle ablation

Radiofrequency needle ablation technology mainly relies on radiofrequency therapeutic apparatus with ablation and cutting functions, and the treatment mechanism is mainly thermal effect. When radiofrequency current flows through human tissues, the rapid change of electromagnetic field will cause the polar water molecules in tissues to move at high speed, generating heat (endogenous heat effect), resulting in the evaporation, drying, shrinkage and shedding of water inside and outside cells, resulting in aseptic necrosis, so as to achieve the purpose of treatment.
