Ultrasonic surgical instrument blades
First Claim
1. A surgical instrument, comprising:
- a transducer configured to produce vibrations at a predetermined frequency;
a waveguide coupled to the transducer and defining a longitudinal axis;
a tube comprising an outer surface, wherein the waveguide extends through the tube; and
an end effector, comprising;
a surgical blade extending from the waveguide, wherein the surgical blade is asymmetric relative to the longitudinal axis, and wherein the surgical blade comprises;
a cutting edge on a first side of the longitudinal axis, wherein the cutting edge comprises a proximal end;
an atraumatic surface on a second side of the longitudinal axis;
a distal tip; and
a treatment portion extending between the proximal end of the cutting edge and the distal tip; and
wherein the surgical instrument further comprises;
a protective sheath extending around at least a portion of the tube and along at least a portion of the surgical blade to the treatment portion.

Abstract
A surgical instrument is disclosed. The surgical instrument includes a transducer, a waveguide coupled to the transducer and defining a longitudinal axis, a tube comprising an outer surface, an end effector, and a protective sheath. The waveguide extends through the tube. The end effector includes a surgical blade extending from the waveguide. The surgical blade is asymmetric relative to the longitudinal axis. The surgical blade includes a cutting edge on a first side of the longitudinal axis, an atraumatic surface on a second side of the longitudinal axis, a distal tip, and a treatment portion. The cutting edge includes a proximal end. The treatment portion extends between the proximal end of the cutting edge and the distal tip. The protective sheath extends around at least a portion of the tube and along at least a portion of the surgical blade to the treatment portion.
