摘要： A surgical apparatus comprises a body, a shaft assembly, and an end effector. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with an ultrasonic transducer via an acoustic waveguide that extends through the shaft assembly. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade along a first angular path from a first position to a second position to thereby provide a tissue sealing mode of operation. The clamp arm is further configured to pivot about a second pivot point toward and away from the ultrasonic blade along second angular path from the second position to a third position to thereby provide a tissue cutting and sealing mode of operation. The second pivot point is proximal to the first pivot point.

摘要： A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation lock assembly. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer and includes a flexible portion. The articulation section is coupled with the shaft and encompasses the flexible portion of the waveguide. The articulation section comprises a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation lock comprises a tensioning feature, which is configured to selectively apply tension to at least one of the first member and the second member of the articulation section to thereby increase rigidity in the articulation section.

摘要： Surgical instruments including a shaft, a jaw assembly and an ultrasonic assembly are disclosed. The shaft may extend along a shaft axis. The jaw assembly may be coupled to a distal end of the shaft and may include a first jaw member and a second jaw member. The jaw assembly may be configured to pivot about a first axis between a first location and a second location. The first and second jaw members may be positioned substantially parallel to the shaft axis at the first location and the first and second jaw members may be positioned at an angle from the shaft axis at the second location. The ultrasonic assembly may comprise an ultrasonic blade, a waveguide, and a transducer. The ultrasonic assembly may be positioned substantially parallel to and offset from the shaft axis and may be axially translatable to at least partially retract the ultrasonic blade within the shaft.

摘要： Various embodiments described herein are directed to ultrasonic blades. For example, an ultrasonic blade may comprise a proximally positioned straight section extending along a longitudinal axis and a distally positioned curved section coupled to the straight section and curved away from the longitudinal axis. The curved section may define a radius of curvature and subtend a first angle. A point of tangency between the curved section and the straight section may be positioned at either a node of the ultrasonic blade or an anti-node of the ultrasonic blade.
