  • Patent number: 10426508
    Abstract: A disposable ultrasonic surgical handle includes a disposable handle body defining a battery-holding compartment shaped to receive a battery therein and operable to couple a proximal end of an ultrasonic waveguide to an ultrasonic transducer therethrough. The body has a transducer dock exposed to the environment and interchangeably housing the transducer and a waveguide attachment dock shaped to align and attach the proximal end of the waveguide to the transducer and hold them at the body when the respectively docked at the transducer and attachment docks. A disposable driving-wave generation circuit in the handle body electrically contacts the battery and the transducer when the battery and the transducer are disposed respectively in the battery-holding compartment and the transducer dock. The circuit generates an output waveform sufficient to cause ultrasonic movement along the waveguide by exciting the transducer when the transducer is coupled to the waveguide.

  • Patent number: 10420579
    Abstract: An ultrasonic surgical instrument is disclosed including a transducer, an ultrasonic blade operably coupled to the transducer, and a control circuit. The control circuit is configured to provide a drive signal to the transducer to cause the transducer to transmit ultrasonic vibrations to the ultrasonic blade, detect a change in a vibration frequency of the ultrasonic blade based at least in part on a change in a frequency of the drive signal, wherein the change in the vibration frequency of the ultrasonic blade corresponds to a tissue condition of tissue treated with the ultrasonic blade, and modify the drive signal in response to the tissue condition.

  • Patent number: 10405876
    Abstract: A surgical apparatus includes a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and a restricting member. 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 is operable to flex to thereby deflect the end effector from a longitudinal axis defined by the shaft. The restricting member is operable to restrict lateral deflection of the end effector. The restricting member is further operable to cooperate with a translating member to rigidize the articulation section when the end effector is aligned with the longitudinal axis. Such rigidization includes removing any “play” or other small movement that might otherwise be provided by the articulation section due to manufacturing tolerances and/or looseness between parts.
