Abstract: Various forms are directed to systems and methods for dissection and coagulation of tissue. A surgical instrument includes an end effector configured to dissect and seal tissue at a distal end thereof, and a selector switch having a plurality of surgical modes. A generator is electrically coupled to the surgical instrument and is configured to deliver energy to the end effector. Each surgical mode of the selector switch corresponds to an algorithm for controlling the power delivered from the generator to the end effector, and each algorithm corresponding to the plurality of surgical modes is configured to allow a user to control the power output level of the generator.

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 is disclosed including an end effector, a generator configured to deliver adaptive energy, a mode selector switch having a plurality of surgical modes, a closure switch configured to control the end effector, and a counter configured to count a number of closure switch activations. The surgical instrument is configured to communicate a selected surgical mode of the mode selector switch and the number of closure switch activations from the counter to the generator. The surgical instrument is configured to receive the adaptive energy from the generator based on the selected surgical mode and the number of closure switch activations. The generator is configured to deliver the adaptive energy to the surgical instrument closer to a start of an activation cycle for the selected surgical mode as the number of closure switch activations increases.

Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive 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. The articulation section includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state.

Abstract: An ultrasonic instrument includes a body, an actuation assembly, a shaft assembly, and an end effector. The actuation assembly includes a mode selection member and an activation member. The shaft assembly extends distally from the body. The shaft assembly includes an acoustic waveguide. The end effector includes an ultrasonic blade. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The end effector is configured to be activated in a first activation mode in response to actuation of the activation member when the mode selection member is in a first position. The end effector is configured to be activated in a second activation mode in response to actuation of the activation member when the mode selection member is in a second position.

Abstract: Aspects of the present disclosure are presented for a surgical instrument for cutting and sealing tissue. In some embodiments, the surgical instrument includes a handle assembly, a shaft, and an end effector. The end effector may include: a blade that vibrates at an ultrasonic frequency, a shielded portion enclosing a back edge of the blade, a high-friction surface coupled to the shielded portion and positioned between the shielded portion and the back edge of the blade. A space is defined between the high-friction surface and the back edge of the blade when the end effector is in a cutting configuration. In a sealing configuration, the high-friction surface contacts the back edge of the blade, which generates heat based on ultrasonic vibrations of the blade rubbing against the high-friction surface. The shielded portion can coagulate bleeding tissue based on heat transfer from the high-friction surface to the shielded portion.
