Abstract: An apparatus comprises a body assembly and a shaft extending distally therefrom. The shaft defines a longitudinal axis. The apparatus further comprises an acoustic waveguide and an articulation section coupled with the shaft. A portion of the articulation section encompasses a flexible portion of the waveguide. The articulation section further comprises first member and a second member that is longitudinally translatable relative to the first member. The apparatus further comprises an end effector including an ultrasonic blade in acoustic communication with the waveguide. A distal portion the ultrasonic blade is disposed in a first direction away from the longitudinal axis at a bend angle. The end effector also includes a clamp arm that is coupled with the first member and the second member, and an articulation drive assembly operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis in the first direction.

Abstract: A surgical apparatus comprises a body assembly, an ultrasonic transducer, a shaft assembly, a motor, and a locking feature. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft assembly comprises a waveguide operable to transmit ultrasonic vibrations. The motor is operable to rotate the ultrasonic transducer to thereby selectively couple the ultrasonic transducer with the waveguide. The locking feature is configured to selectively prevent rotation of at least a portion of the shaft assembly relative to the body assembly. The locking feature and the motor may be activated automatically in response to an operator positioning a proximal portion of the shaft assembly in a distal portion of the body assembly. The surgical apparatus may include a feature configured to alert a user when the waveguide has been adequately secured to the ultrasonic transducer.

Abstract: Various aspects of a generator, ultrasonic device, and method for estimating a state of an end effector of an ultrasonic device are disclosed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance is defined as Zg(t)=Vg(t)/Ig(t). The control circuit receives a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis.

Abstract: Various embodiments are directed to articulatable surgical instruments. Some embodiments comprise an end effector to treat tissue, where the end effector comprises an ultrasonic blade. A hollow shaft may extend proximally from the end effector along a longitudinal axis. A waveguide may extend through the shaft and may be acoustically coupled to the ultrasonic blade. The waveguide may comprise a distally positioned flange positioned within the hollow shaft proximally from the blade and may be held stationary at a first pivot point positioned within the hollow shaft proximally from the flange. A reciprocating wedge may be positioned within the hollow shaft such that distal motion of the wedge pushes the wedge between the flange and the hollow shaft, causing the ultrasonic blade to pivot about the first pivot point in a first direction.

Abstract: Various example embodiments described herein are directed to articulating surgical instruments for treating tissue comprising an end effector and a shaft extending proximally from the end effector along a longitudinal axis. In certain embodiments, the shaft comprises a plurality of transverse spacer members as well as first and second rotatable members extending through at least a portion of the plurality of transverse spacer members. The first and second rotatable members may both be biased away from the longitudinal axis such that their respective directions of bias vary with rotation of the first rotatable member. When the respective directions of bias of the first and second rotatable members oppose one another, the shaft may be substantially straight. When the respective directions of bias of the first and second rotatable members are aligned with one another, the shaft may articulate away from the longitudinal axis in the direction of the alignment.
