Abstract: A surgical instrument is configured to compensate for battery pack and drivetrain failures. One method includes generating a firing sequence, determining whether a subset of rechargeable battery cells is damaged during the firing sequence, and stepping-up an output voltage of the battery pack to complete the firing sequence in response to a determination that a subset of the rechargeable battery cells is damaged. Another method includes generating a mechanical output to motivate a drivetrain to transmit a motion to a jaw assembly of the surgical instrument, activating a safe mode in response to an acute failure of the drivetrain, and activating a bailout mode in response to a catastrophic failure of the drivetrain. Another method includes driving a drivetrain, sensing and recording vibration information from the drivetrain, generating an output signal based on the vibration information, and determining a status of the surgical instrument based on the output signal.

Abstract: A surgical instrument for treating tissue comprising a shaft, an end effector rotatably coupled to the shaft, and a firing member configured to be moved relative to the end effector is disclosed. The surgical instrument further comprises an articulation member operably coupled with the end effector, wherein the articulation member is selectively engageable with the firing member such that the articulation member is operably engaged with the firing member in an engaged configuration and such that the articulation member is operably disengaged from the firing member in a disengaged configuration, and wherein the firing member is configured to move the articulation member relative to the end effector to articulate the end effector when the articulation member and the firing member are in the engaged configuration.

Abstract: The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

Abstract: Devices and methods are provided for removably coupling a cartridge to an end effector of a surgical device. In general, one of a cartridge and a surgical device can include at least one mating element, and the other of the cartridge and the surgical device can include at least one engagement feature configured to removably engage the at least one mating element. The engagement of the at least one mating element and the at least one engagement feature can help ensure that the cartridge is fully mated to the surgical device such that the surgical device can properly fire fasteners disposed within the cartridge. The engagement of the at least one mating element and the at least one engagement feature can be configured to provide a positive indication that the cartridge is fully seated in an end effector of the surgical device.

Abstract: A method includes grasping a user input device in communication with a surgical tool of a robotic surgical system, the surgical tool including an end effector with opposing jaws, squeezing the user input device and thereby actuating a motor that closes the jaws and clamps down on tissue at a surgical site, and calculating with a computer system in communication with the surgical tool work completed by the motor to close the jaws and clamp down on the tissue. The computer system generates one or more effort indicators when the work completed by the motor meets or exceeds one or more predetermined work increments corresponding to operation of the motor, and communicates the one or more effort indicators to an operator.
