This is an electrosurgery Electrode used for cutting or coagulation of tissue. It may be in the shape of a knife, needle, ball or loop. The Electrodes with a small contact area with the tissue are used for cutting and excising sections of tissue, employing the cutting action of high-frequency (0.5-4 MHz) continuous wave currents. Electrodes with large surface areas are used for coagulation, drawing sparks from high-voltage pulses on to the tissue to arrest bleeding.
