Innovative cost-effective insulated needle probe for intralesional radiofrequency

Intralesional radiofrequency (ILRF) is a treatment that delivers energy directly into lesions while sparing the outer skin layer. This reduces the chances of post-inflammatory marks and scarring. ILRF when used for smaller size lesions such as papular scars, syringoma, and electrolysis epilation probes are available conventionally where a stainless steel electrode is coated with polytetrafluoroethylene (Teflon). There are multiple problems faced with such probes such as frequent breakage, bending, and adverse events like post-inflammatory hyperpigmentation. An innovative and cost-effective insulated needle probe has been developed using a needle from a microneedle radiofrequency probe. This advanced design minimizes the adverse effects commonly associated with conventional probes while enhancing efficacy using superior-quality materials.
