Abstract: A method for controlling an operation of an ultrasonic blade of an ultrasonic electromechanical system is disclosed. The method includes providing an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade via an ultrasonic waveguide; applying, by an energy source, a power level to the ultrasonic transducer; determining, by a control circuit coupled to a memory, a mechanical property of the ultrasonic electromechanical system; comparing, by the control circuit, the mechanical property with a reference mechanical property stored in the memory; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the comparison of the mechanical property with the reference mechanical property.

Abstract: Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.

Abstract: An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The body comprises a pivotal trigger. The shaft couples the end effector and the body together. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue. Pivotal movement of the trigger causes movement of the clamp arm. The trigger includes a compliant feature configured to limit the amount of force delivered to tissue by the clamp arm. The flexible feature may comprise a flexible band, living hinge, a series of living hinges, or a flexible tab.

Abstract: A surgical instrument including a shaft including a distal portion and an articulatable portion is disclosed. The articulatable portion, positioned proximal to the distal portion, includes a plurality of joint members. A first articulation cable extends through each first channel of each of the plurality of joint members and a second articulation cable extends through each second channel of each of the plurality of joint members to the distal portion. The first and second articulation cables are transitionable between: (i) an unlocked state, where the first and second articulation cables are free to translate distally and proximally and the plurality of joint members are slidable relative to one another to pivot the distal portion away from a longitudinal axis, and (ii) a locked state, where translation of the first and second articulation cables is locked, causing a position of the distal portion relative to the longitudinal axis to be locked.
