Plastic surgery electrode TNFS102A

ENTneurosurgicalelectrosurgical

Overview
Reusable tungsten needle electrode designed for precision electrosurgery. The TNFS102A combines an ultra-fine tungsten tip and insulated shaft to perform simultaneous cutting and coagulation in delicate procedures while limiting thermal spread and surgical plume.

Key features

• High-precision cutting: ultra-fine tungsten tip with a curvature radius of 50 μm for sub-millimeter cutting accuracy to minimize collateral tissue trauma.
• Simultaneous cutting and coagulation: employs high-frequency current to deliver controlled cutting with concurrent hemostasis, improving intraoperative visibility.
• Thermal resistance and edge retention: tungsten tip (melting point >3400°C) maintains sharpness and dimensional stability under electrosurgical conditions.
• Low-power effective operation: optimized for micro-area electrosurgical waveforms to reduce tissue necrosis and surgical smoke.
• Insulated safety design: heat-resistant polymer shaft with high dielectric strength; only 3 mm of the needle tip is exposed to reduce accidental burns.
• Reusable: engineered for multiple uses to lower per-procedure cost; reuse should follow institutional sterilization and inspection protocols.

Applications

• Plastic and reconstructive surgery: precise skin and soft-tissue incision with controlled coagulation to minimize scarring.
• Neurosurgery: fine dissection in brain and spinal procedures with reduced collateral damage to neural structures.
• Ophthalmic surgery: microsurgical maneuvers on ocular tissues requiring extreme precision.
• ENT (otolaryngology): targeted cutting and coagulation in delicate head and neck procedures.
