1. A surgical instrument, comprising:
- a transducer configured to produce vibrations at a predetermined frequency;
an ultrasonic end effector extending along a longitudinal axis coupled to the transducer;
a controller to receive a feedback signal from the ultrasonic end effector; and
a lumen adapted to couple to a pump, wherein the lumen is to conduct a fluid therethrough based on the feedback signal.

Abstract
A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. An ultrasonic blade extends along a longitudinal axis and is coupled to the transducer. A controller receives a feedback signal from the ultrasonic blade. A lumen is adapted to couple to a pump. The lumen conducts a fluid therethrough based on the feedback signal.
