The Triangular Electrode High-Frequency Electrosurgical Knife is a surgical instrument used for cutting and coagulating tissue during operations. Its triangular-shaped electrode allows for precise and controlled incisions, especially in areas that require detailed work. By utilizing high-frequency electrical currents, the knife not only cuts through tissue but also cauterizes it, reducing bleeding and improving surgical efficiency. This tool is commonly used in various surgical procedures, including delicate and complex surgeries.
