  • Patent number: 10667835
    Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

  • Patent number: 10667818
    Abstract: An apparatus includes a handle assembly, an end effector, a firing assembly, and a lockout assembly. The handle assembly includes first and second arms and a latching lever. The end effector includes first and second jaws and a staple cartridge. The firing assembly is configured to actuate from a pre-fired proximal position toward a distal position in order to staple and sever tissue captured between the first jaw and the second jaw. The lockout assembly is configured to prevent distal translation of the firing assembly in a locked configuration and allow distal translation of the firing assembly in an unlocked configuration. The latching lever is configured to actuate the lockout assembly from the locked configuration to the unlocked configuration in response to the latching lever pivoting the second jaw from a partially closed configuration to a fully closed configuration while the firing assembly is in the pre-fired proximal position.

  • Publication number: 20200163686
    Abstract: An ultrasonic forceps comprises a housing, an acoustic assembly, and a tine. The housing joins the acoustic assembly and the tine to the forceps and permits the tine to pivot relative to the acoustic assembly. The acoustic assembly comprises a transducer, a waveguide, and ultrasonic blade, and a waveguide sheath. The transducer is configured to generate ultrasonic vibrations directing the ultrasonic vibrations to the waveguide. The waveguide communicates the ultrasonic vibrations distally to the ultrasonic blade. The ultrasonic blade is configured to vibrate in response to the ultrasonic vibrations generated by the transducer. When the tine is pivoted relative to the transducer, the tine is configured to move toward the ultrasonic blade. Tissue may be grasped between the tine and the ultrasonic blade. The tissue may be denatured when the ultrasonic vibrations generated by the transducer vibrate the ultrasonic blade, thus resulting in the tissue being cut and/or sealed.
