"Monopolar" refers to a system or device that has a single pole or electrode. In electrical terms, it often describes a circuit where current flows from one point to a single return path, typically used in applications like monopolar electrosurgery. This technique uses a single active electrode to cut or coagulate tissue, making it effective in surgical procedures. In contrast to bipolar systems, which have two electrodes, monopolar systems can cover larger areas and are often more versatile. However, they may also carry a higher risk of unintended damage to surrounding tissues due to the broader current flow.
