Abstract
An ultrasonic surgical blade with an improved heel portion is disclosed. The blade includes a solid body, a longitudinal portion having a proximal end configured to couple to an ultrasonic transmission waveguide and a transverse portion extending crosswise from the distal end of the longitudinal portion. At least one dissection edge and at least one hemostasis surface is provided on the blade. The transverse portion defines a hook having a free end configured to pull and dissect tissue. The blade further comprises a tissue plow comprising a plow edge and a distal-most vertex to increase the efficiency of heel dissection and tissue diversion.
