Abstract
A surgical instrument is disclosed including a transducer configured to produce vibrations along a longitudinal axis at a predetermined frequency and an ultrasonic blade extending along the longitudinal axis coupled to the transducer. The ultrasonic blade includes a body having a proximal end and a distal end. The distal end is movable along the longitudinal axis by the vibrations produced by the transducer. The surgical instrument further includes a protective sheath including a proximal end and a distal end and disposed adjacent to the body. The protective sheath further includes a pad positioned toward the distal end of the protective sheath and located between the body and the distal end of the protective sheath.
