A sterile electrosurgical device which consists of a handpiece with mechanical and/or electrical controls, and a monopolar electrode, intended to deliver electrosurgical current from a system generator directly to tissues for cutting/coagulation/ablation during endoscopic (including laparoscopic, arthroscopic) surgery. It includes a long thin electrode connected to the handpiece and may include a lumen for suction/irrigation; it requires a patient contact return electrode to complete the circuit. It is available in a variety of forms (e.g., forceps or snare with ring handles, rigid probe with controls) and may be designed to also mechanically cut tissues. This is a single-use device.
