摘要：
An ultrasonic instrument comprises an ultrasonic transducer, an acoustic waveguide, and an ultrasonic blade. The blade includes a pair of obliquely extending edges. The obliquely extending edges diverge away from the longitudinal axis of the waveguide and away from each other along respective paths extending distally in relation to the waveguide. A distal portion of the blade is wider than a proximal portion of the blade along a plane. The blade further includes a curved distal edge and several laterally presented surfaces. The laterally presented surfaces may provide combinations of concave and convex curvatures. The laterally presented surfaces may be angled and/or curved along one or more orthogonal planes associated with the longitudinal axis of the waveguide.
