A electrosurgical device intended to be connected directly to the arm of a robotic surgical system to deliver electrosurgical current in a bipolar configuration (i.e., without a return electrode) from a generator directly to tissues for cutting/coagulation/ablation during robotic endoscopic (e.g., laparoscopic, arthroscopic) surgery. It includes a long thin body with a proximal housing intended to attach to the robotic arm, and may include the distal bipolar electrode in one of a variety of forms (e.g., forceps, hook). This is a single-use device.
