  • Publication number: 20190239977
    Abstract: Methods and surgical instruments are provided for determining a relative state of charge of a battery used during a surgical procedure. The surgical instrument includes an end effector configured to treat tissue with energy, and a user interface configured to receive an input. A generator is coupled to the end effector, and the battery communicates with the generator. A controller includes a processor and a memory having instructions stored thereon which, when executed by the processor, cause the processor to detect an input at the user interface. In response to the detected input at the user interface, a discharge profile is matched to the detected input. The discharge profile corresponds to a discharge curve representing current discharge over time. A relative state of charge is then identified from the discharge curve based on usage of the surgical instrument during a surgical procedure.

  • Patent number: 10338115
    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: 20190059997
    Abstract: A system facilitating planning of a surgical procedure includes one or more storage devices, one or more input devices, a processor, and a memory. The storage device(s) stores, for previous surgical procedures, surgical instrument information, procedure information, and patient information. The input device(s) is configured to receive procedure information and patient information corresponding to a surgical procedure to be performed. The memory stores instructions that, when executed by the processor, cause the processor to identify similar previous surgical procedures, identify outcome information for each of the similar previous surgical procedures, determine whether there is a correlation between the surgical instrument information of the similar previous surgical procedures and the outcome information of the similar previous surgical procedures, and, if a correlation is determined, output the correlation to facilitate planning of the surgical procedure to be performed.

  • Patent number: 10172612
    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.
