Abstract: A surgical instrument can comprise a handle, a shaft extending from the handle, and an end effector rotatably coupled to the shaft by an articulation joint. The surgical instrument can further include a staple cartridge positioned within the end effector and a firing drive operably coupled with a trigger wherein the operation of the trigger can advance and/or retract a firing member of the firing drive relative to the end effector. The surgical instrument can further comprise an articulation drive which is selectively engageable with the firing drive. When the articulation drive is engaged with the firing drive, the operation of the firing drive can operate the articulation drive and articulate the end effector. When the articulation drive is not engaged with the firing drive, the firing drive can be operated independently of the articulation drive.

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.

Abstract: A surgical instrument. The surgical instrument includes an elongated channel configured to support a staple cartridge, an anvil pivotably connected to the elongated channel, a knife mechanically coupled to the staple cartridge, an electric motor and a control circuit electrically connected to the electric motor. The control circuit is configured to change a firing motion a first way based on a first value of a projected peak firing force and a second way based on a second value of the projected peak firing force value.

Abstract: A surgical stapler. The surgical stapler includes a drive system, an electric motor, a battery and a control system. The electric motor is mechanically coupled to the drive system. The battery is electrically couplable to the electric motor. The control system is electrically connected to the electric motor and includes an H-bridge circuit, an electrically resistive element and an electrically inductive element. The H-bridge circuit includes a high side and a low side. The low side of the H-bridge circuit includes first and second switching devices. The electrically resistive element is electrically connected in series with the first switching device. The electrically inductive element is electrically connected to the electrically resistive element. The control system is configured to control a force applied to the drive system based on a current downstream of the electrically resistive element.

Abstract: Surgical stapling systems and methods for stapling tissue during a surgical procedure are provided. In an exemplary embodiment, a control system is provided for controlling at least one motor coupled to a drive system on a surgical stapling device for driving one or more drive assemblies. The control system can be configured to communicate with the drive system of the stapling tool and to control and modify movement of one or more drive assemblies based on certain feedback.

Abstract: Various systems and methods of controlling a surgical instrument are disclosed. The surgical instrument can include one or more sensors that are configured to detect or measure parameters associated with the use of the instrument and a display. A control circuit can be configured to detect whether the instrument is articulating, firing, clamping, and so on according to relationships between the detected parameters. The control circuit can further cause the display to display an image or sequences of images according to the particular operational state of the instrument. The images can provide alerts, instructions on how to use the instrument, or information detected by the one or more sensors, such as the position of the knife during transection.

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.
