  • Publication number: 20200214731
    Abstract: Thresholds can be assigned for one or more parameters in connection with the operation of a surgical device. An ultimate threshold can trigger a desired action, including cessation of operations or modification of operations, if the ultimate threshold is reached, or predicted to be reached. In addition, a marginal threshold can trigger a desired action, including improving operations such as slowing operations where the value of a parameter is measured to be between the values defined by a marginal threshold and an ultimate threshold. Multiple thresholds, based on multiple parameters, can be defined, further enabling calibrated usage, such as slowing operations based on exceeding both a marginal threshold based on number of sterilization cycles and exceeding a marginal threshold based on extent to which current draw exceeds a certain value.

  • Patent number: 10695081
    Abstract: A surgical instrument includes an end effector, a motor for opening and closing the jaws, a sensor configured to detect a tissue compression parameter associated with a tissue between the jaws, and a control circuit. The control circuit is configured to determine a value of the tissue compression parameter via the sensor as the jaws transition from the open configuration to the closed configuration, cause the motor to increase a time to transition the jaws to the closed configuration according to whether the value of the tissue compression parameter is above a first threshold, and provide feedback according to whether the value of the tissue compression parameter is below a second threshold.

  • Patent number: 10695140
    Abstract: Various exemplary methods, systems, and devices for near field communication (NFC) between a surgical instrument and a robotic surgical system are provided. In general, a surgical tool is configured to move between different modes of communication with a robotic surgical system to which the tool is releasably and replaceably coupled. The different modes of communication are detectable by the robotic surgical system by the tool's frequency of NFC with the robotic surgical system. The tool includes a mechanism configured to be manipulated by a user of the tool to move the tool between the different modes of communication. The tool operating in a first mode of communication indicates to the robotic surgical system that the tool is operating in a normal state. The tool operating in each of one or more additional modes of communication indicates that the tool is operating in an error state.

  • Patent number: 10687806
    Abstract: A mechanism is disclosed for adapting operations of a surgical instrument based on data from actual, expected or predicted properties of tissue, data from measuring operation of the surgical instrument itself, and data based on clinician conduct. The adaptive measures can be based on predetermined control measures such as algorithms stored in operative communication with the surgical instrument, based on dynamically generated control measures, or a combination of both. Utilizing such mechanisms can help to adjust closure and firing algorithms based on tissue properties, improve battery usage, and learn from user operations, enhancing functioning of the instrument within an operational envelope.
