摘要： An ultrasonic surgical blade (112) includes a body (108) having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis (A) in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating (116) adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

摘要： An ultrasonic instrument comprises a handle assembly configured to receive an ultrasonic transducer, a shaft assembly having an acoustic waveguide and an ultrasonic blade, and a retractable clamp arm. The ultrasonic blade is in acoustic communication with the acoustic waveguide such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically via the acoustic waveguide. The clamp arm is configured to selectively translate between an inoperative position and an operative position. The clamp arm is positioned generally proximal to the ultrasonic blade when the clamp arm is in the inoperative position. The clamp arm is positioned lateral to the ultrasonic blade when the clamp arm is in the operative position. When in the operative position, the clamp arm is operable to move toward and away from the ultrasonic blade so as to capture and compress tissue between the clamp arm and the ultrasonic blade.

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.

摘要： A surgical apparatus comprises a transducer assembly and a shaft assembly. The transducer assembly is operable to convert electrical power into ultrasonic vibrations. The shaft assembly comprises an ultrasonic waveguide, a sheath, a shroud, and a torque transfer assembly. The waveguide is configured to couple with the transducer assembly. The waveguide is disposed within the sheath. The sheath extends through the shroud. The torque transfer assembly is contained within the shroud. The torque transfer assembly is configured to transfer a predetermined range of torque from the shroud to the waveguide to thereby couple the waveguide with the transducer assembly. The torque transfer assembly is further configured to prevent transfer of torque from the shroud to the waveguide beyond an upper limit of the predetermined range.

摘要： An end effector comprises a first jaw, a second jaw, a firing beam, and a lockout feature. The second jaw pivots relative to the first jaw from an open position to a closed position. The firing beam has a sharp distal end and translates between the first and second jaws. The firing beam translates from a proximal position to a first distal position to pivot the second jaw to the closed position. The end effector applies bipolar RF energy when the firing beam is in the first distal position. The firing beam then translates to a second distal position to sever tissue captured between the first and second jaws. The lockout feature prevents the firing beam from advancing from the first distal position to the second distal position until the lockout feature is actuated.
