Abstract
An improved electrode assembly for a resectoscope includes at least one electrical lead that connects at a proximal end via a handle of the resectoscope to an electrosurgical generator to receive electrical power. The electrode assembly further includes an electrode tip at a distal end. The electrode tip has a surface that includes at least one aperture and preferably multiple apertures that extend through the tip. The aperture serves to increase the area of the electrode tip relative to its mass thereby increasing the performance of the electrode for cutting, ablating, vaporizing, or coagulating tissue. The electrode tip performs these functions with relatively lower power requirements compared to conventional resectoscope electrodes.
