Tungsten Needle Electrode in Minimally Invasive Surgery
Tungsten needle electrodes are precision conductive electrodes used in minimally invasive surgery, including high-frequency electrosurgical systems, radiofrequency ablation equipment, and interventional medical devices. Tungsten offers high melting point, high density, excellent electrical conductivity, and outstanding dimensional stability at elevated temperatures, enabling stable discharge and energy transmission under high-frequency current. Compared with conventional metal electrodes, tungsten needle electrodes provide superior tip erosion resistance, excellent dimensional consistency, high machining precision, and long service life, making them widely used in minimally invasive surgical instruments and high-frequency energy delivery systems.
