Abstract

A surgical instrument includes an ultrasonic transducer, an ultrasonic transmission waveguide extending from the ultrasonic transducer, and an ultrasonic blade acoustically coupled to the ultrasonic transmission waveguide. The ultrasonic blade includes a base and a curved body extending distally from the base. The curved body includes a tissue-treating surface extending on a first side of the curved body and a curved edge extending on a second side of the curved body opposite the first side. The curved edge has a proximal end and a distal end, wherein the proximal end is offset from the distal end in a first direction, wherein the proximal end is offset from the distal end in a second direction, and wherein the first direction is perpendicular to the second direction.
