Abstract
An improved electrode assembly for a resectoscope and methods for use thereof. The electrode assembly 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 non-rotating, relatively flat, working surface that extends in a longitudinal direction. The tip can be used for ablation or coagulation by using the working surface. The tip includes an edge that can be used for cutting. The working surface includes a pattern that enhances generation of a current therefrom. The electrode tip is versatile so that the same tip can be used for cutting, vaporizing, ablating, and coagulating.
