1. A surgical instrument usable with a fluid system, wherein the surgical instrument comprises:
an ultrasonic waveguide; and
an end effector comprising:
an ultrasonic blade in ultrasonic communication with the ultrasonic waveguide and defining a longitudinal axis, wherein the ultrasonic blade is movable along the longitudinal axis in response to ultrasonic vibrations applied to the ultrasonic waveguide by an ultrasonic transducer;
a jaw movable relative to the ultrasonic blade to capture tissue therebetween, wherein the ultrasonic blade is configured to provide ultrasonic energy to the tissue as the ultrasonic blade moves along the longitudinal axis; and
a fluid line in fluid communication with the fluid system, wherein the fluid line is configured to receive fluid from the fluid system, wherein the fluid is configured to be in thermal communication with the ultrasonic blade, wherein the fluid line is configured to adjust a temperature of the ultrasonic blade using the fluid.
