Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A surgical instrument, comprising: a transducer configured to produce vibrations at a predetermined drive frequency; an ultrasonic blade coupled to the transducer; an ultrasonic transmission waveguide coupled between the transducer and the ultrasonic blade; a controller to receive a feedback signal from at least the ultrasonic blade, wherein the feedback signal is a frequency variation between the predetermined drive frequency of the transducer and a r…
