Abstract

A surgical instrument is disclosed. The surgical instrument comprises an end effector comprising an ultrasonic blade and a clamp arm. The clamp arm is movable relative to the ultrasonic blade to transition the end effector between an open configuration and a closed configuration to clamp tissue between the ultrasonic blade and the clamp arm. The surgical instrument further comprises an ultrasonic transducer configured to generate an ultrasonic energy output and a waveguide configured to transmit the ultrasonic energy output to the ultrasonic blade. The surgical instrument further comprises a control circuit, configured to detect an immersion of the end effector in a liquid and compensate for heat flux lost due to the immersion of the end effector in the liquid.
