Abstract: An electrosurgical instrument includes a pair of jaws, an endoscope configured to capture image data of a surgical site including the electrosurgical instrument, and an energy generator coupled to the electrosurgical instrument. The energy generator is configured to generate an energy output to the electrosurgical instrument. The system also includes an endoscope controller which includes a processor and a memory. The memory includes instructions stored thereon, which, when executed by the processor, cause the energy-based surgical system to access the captured image, determine a thickness of tissue grasped by the pair of jaws based on the image, and control the energy output of the energy generator based on the determined thickness.
