  • Patent number: 10073125
    Abstract: A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.

  • Publication number: 20180250093
    Abstract: Systems and methods are provided for improving medical instruments and devices. One system includes a surgical instrument associated with an instrument identifier, and an electrosurgical generator operably coupled to the surgical instrument. The electrosurgical generator is associated with a generator identifier and is configured to receive and store data associated with an operating mode of the surgical instrument, receive data associated with the instrument identifier from the surgical instrument, generate a unique identifier based on a time and date at which the surgical instrument is operably coupled with the electrosurgical generator for the first time, the generator identifier of the electrosurgical generator, and the instrument identifier, and associate the unique identifier with the stored data associated with the operating mode of the surgical instrument.

  • Patent number: 9974524
    Abstract: A biopsy instrument for removing nodes such as lymph nodes may include one or more of a blade for mechanical cutting of the ducts that connect the node to surrounding tissue and/or an energy emitter for emitting energy to seal the ducts and/or contribute to the gentle removal of the node from its connecting ducts. The biopsy instrument may include a ring clamp assembly made up of two opposing ring structures that may be clamped together such that the desired tissue sample (e.g., a lymph node) is captured within the inside opening of the clamped rings. Connecting ducts may be severed using either a blade or energy emitted from the ring clamps.

  • Publication number: 20160206336
    Abstract: A surgical instrument including a housing, an elongated portion, an end effector, a drive beam and a force applier is provided. The housing includes a first actuator and a second actuator. The elongated portion extends distally from the housing and defines a longitudinal axis. The end effector is disposed adjacent a distal portion of the elongated portion, and includes a first jaw member and a second jaw member. The first jaw member has a cavity defined therein. Actuation of the first actuator causes distal translation of the drive beam to move the first jaw member relative to the second jaw member toward the approximated position, which applies a fist force against tissue disposed between the jaw members. Actuation of the second actuator causes distal translation of the force applier such that at least a portion of the force applier moves into the cavity of the first jaw member and applies an additional force against tissue disposed between the jaw members.
