Abstract
Surgical systems include an ultrasonic device, a generator coupled to the ultrasonic device, and a return pad. The generator is configured to control supply of the ultrasonic energy to the ultrasonic device and control supply of an energy pulse to the ultrasonic device at different times. The ultrasonic device generates a current pulse signal in response to the energy pulse. The generator also measures a current feedback signal at the return pad, the current feedback signal resulting from the current pulse signal, and estimate a tissue property of tissue grasped by the ultrasonic device based on the current feedback signal.
