High-frequency electrodes for handheld devices are primarily used in urology for electrosurgical procedures in the bladder, prostate, and urethra. It is known that a large active electrode area is advantageous. However, the size of the area is limited by the available space. Furthermore, higher energy is required to ignite the plasma in large electrodes. Increased energy, however, negatively impacts the temperature input into the irrigation fluid, which can be detrimental to the surrounding tissue. The invention provides a high-frequency electrode (18), an electrode instrument (16), and a resectoscope (10) in which the plasma can be more easily localized at the electrode (18) while simultaneously reducing the energy required to ignite the plasma. This is achieved by giving the high-frequency electrode (18) for use in a surgical handheld device the shape of a toroid (21).
