Self-made insulated needle

Radiofrequency (RF) ablation is a surgical procedure which uses alternating current at ultra-high frequency for controlled tissue destruction. The wide range of dermatological indications includes the management of benign and malignant skin lesions. Certain skin conditions where the target tissue is deeper and epidermal sparing is required such as leukotrichia, trichiasis, cherry angioma, infantile hemangioma, and angioma serpiginosum need more precise energy delivery. These conditions can be addressed by insulated RF for localized tissue destruction without damaging the surface/epidermis and hence reducing the side effects such as post-inflammatory hyper or hypopigmentation and scarring. A simple, non-expensive, commercially available adhesive can be used to coat the normal RF needle for safe cauterization and good cosmetic outcomes.
