Abstract

A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. The transducer is configured to produce vibrations along a longitudinal axis at a predetermined frequency. An ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. The ultrasonic blade includes a body having a proximal end and a distal end. The distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. The body includes a treatment region that extends from the proximal end to the distal end. The body includes a substantially flat broad top surface, a bottom surface, and a neck portion protruding from the proximal end adapted to couple to the transducer.
