Abstract: A surgical instrument includes an end effector, a shaft assembly, and an axial location feature. The end effector includes an ultrasonic blade and a clamp arm that can move between an open and closed position. The shaft assembly includes a proximal shaft portion, an acoustic waveguide extending proximally from the ultrasonic blade, a distal shaft portion extending along a distal axis, and an articulation section interposed between the proximal shaft portion and the distal shaft portion.

The axial location feature can inhibit the ultrasonic blade from shifting relative to the clamp arm along the distal axis as the end effector is driven between the non-deflected position and the deflected position.

Abstract: An ultrasonic device may include an electromechanical ultrasonic system having a resonant frequency, the system including a transducer coupled to an ultrasonic blade. A method of driving the blade may include determining a tissue type contacting the blade, setting current delivered to the transducer to achieve a desired blade temperature, and setting a desired period during which the desired temperature is applied to the tissue. The tissue type may be determined by measuring an impedance of the transducer, comparing an impedance measurement data point to a reference data point, and classifying the impedance measurement data point based on a result of the comparison. Alternatively, the tissue type may be determined by applying a drive signal to the transducer, sweeping the frequency of the drive signal from below to above a resonance of the ultrasonic system, measuring and recording impedance/admittance variables, and comparing the measured variables to reference variables.

Abstract: Aspects of the disclosure relate to cognitive automation-based engine processing on audio files and streams received from meetings and/or telephone calls. A noise mask can be applied to enhance the audio. Real-time speech analytics separate speech for different speakers into time-stamped streams, which are transcribed and merged into a combined output. The output is parsed by analyzing the combined output for correct syntax, normalized by breaking the parsed data into record groups for efficient processing, validated to ensure that the data satisfies defined formats and input criteria, and enriched to correct for any errors and to augment the audio information. Notifications based on the enriched data may be provided to call or meeting participants.
