Methods, instruments, and systems for tissue sealing

Abstract

An ultrasonic surgical system includes an ultrasonic instrument configured to seal a vessel and including an ultrasonically-activatable blade and a jaw member pivotably movable with respect to the blade, an endoscope configured to capture video data of a surgical site including the blade and the jaw member, and a processor connected to the endoscope. The processor is configured to process the video data to determine an angle between the blade and the jaw member, determine a desired energy level based on the angle, and provide the desired ultrasonic energy as a feedback to the ultrasonic instrument. The ultrasonic instrument performs a closed-loop control to maintain the desired ultrasonic energy.
