Electrosurgical Unit

 An Electrosurgical Unit (ESU) is a radiofrequency generator that provides electrical energy for surgical cutting and coagulation. The ESU is a professional-grade system featuring monopolar and bipolar outputs, with safety-critical Return Electrode Monitoring (REM) for monopolar procedures. It is the universal surgical tool for precise tissue dissection with simultaneous hemostasis, used in open, laparoscopic, and endoscopic procedures across all specialties. Safe operation hinges on correct patient return pad placement, awareness of fire risks (especially with oxygen and flammable prep solutions), and adherence to protocols for patients with implanted electronic devices.
