Electrosurgical pencils are specialized surgical instruments used in various medical procedures to cut tissue and coagulate blood. They work by delivering high-frequency electrical currents through a thin electrode tip, which generates heat. This heat effectively vaporizes the tissue, allowing for precise incisions while minimizing bleeding. These pencils are often used in laparoscopic surgery, dermatology, and other surgical fields. They typically come with adjustable settings to control the intensity of the current, providing surgeons with flexibility during operations. Safety features, such as insulation and grounding, are also incorporated to protect both the patient and the medical staff.
