1. A surgical instrument, comprising:
a transducer configured to produce vibrations along a longitudinal axis at a predetermined frequency;
an ultrasonic blade extending along the longitudinal axis coupled to the transducer, wherein the ultrasonic blade comprises a body having a proximal end and a distal end, wherein the distal end is movable along the longitudinal axis by the vibrations produced by the transducer;
a protective sheath comprising a proximal end and a distal end and disposed adjacent to the body, wherein the protective sheath further comprises a pad positioned toward the distal end of the protective sheath and located between the body and the distal end of the protective sheath; and
a non-vibrating clamp arm assembly having a proximal end and a distal end and pivotally positioned adjacent to the body, wherein the clamp arm assembly is pivotally moveable from an open position to a closed position.
