The Birtcher Hyfrecator 733 is a Solid-State electrosurgical unit (ESU) designed for minor procedures in settings like family medicine, dermatology, and gynecology. It uses high-frequency electrical pulses to destroy tissue and coagulate blood vessels, commonly used for tasks such as removing benign skin lesions, treating warts, and controlling bleeding during small excisions. A key feature is its ability to function without a ground pad on the patient.
