Abstract: A surgical instrument comprising an end effector and a closure actuator configured to engage with the end effector is disclosed. The surgical instrument further comprises an articulation drive operable to rotate the end effector about an articulation joint when the closure drive is in its partially-closed position. The surgical instrument further comprises a closure lock biased toward a top portion of the closure actuator and configured to interact with a top notch such that the closure actuator remains in a fully open position, a partially closed position, or a fully closed position.

Abstract: A surgical stapling instrument comprising a tissue cutting knife movable through a staple cartridge to perform a staple firing stroke is disclosed. The stapling instrument further comprises a lockout system configured to prevent the tissue cutting knife from being moved through the staple firing stroke if the staple cartridge is missing from the stapling instrument and/or if the staple cartridge has been previously fired. The lockout system comprises a flexible spring that acts on the bottom of the tissue cutting knife at the initiation of the staple firing stroke to push the tissue cutting knife into a lockout recess if the staple cartridge is missing or has been previously fired.

Abstract: A surgical stapling instrument includes a shaft assembly, an end effector at a distal end of the shaft assembly and having a first jaw with an anvil and a second jaw operable to cooperate with the first jaw to clamp tissue, and a cartridge inserted into the second jaw. The cartridge includes staples, a movable member translatable distally during a firing stroke to discharge the staples into tissue, a first sensor assembly configured to monitor a first condition of the cartridge, and a second sensor assembly configured to monitor a second condition of the cartridge. A first processor is coupled with the first and second sensor assemblies and is configured to receive first and second signals from the sensor assemblies, respectively, where each signal is indicative of the respective condition of the cartridge. The first processor is configured to selectively permit or restrict the firing stroke based upon the signals.

Abstract: A surgical instrument includes a shaft assembly, an end effector, a driving assembly, at least one motor, and a motor controller. The at least one motor is configured to actuate the driving assembly to deploy staples. The motor controller is in communication with the motor. The motor controller is configured to determine whether values of first and second trigger variables exceed predetermined thresholds. The motor controller is configured to modify at least one motor control parameter in response to determining that the values of the first and second trigger variables exceed the predetermined thresholds. The motor control parameters include a motion profile instituted by the motor controller for the motor, a waiting period during which power to the motor is reduced or stopped, or the predetermined threshold relating to current or force for proximal retraction to be different from the predetermined threshold relating to current or force for distal advancement.

Abstract: A surgical stapling system includes an anvil, a blade, a motor and gear assembly, a motor power supply, and a motor controller. A method of controlling the motor includes receiving first and second data indicative of operations of the motor under first and second conditions, respectively, and adjusting a motor control signal based on a difference between the first and second data. Another method includes receiving initial manufacture motor and gear assembly data from a manufacture and operational data during an initial use of the system, and adjusting parameters of the control signal based on a difference between the manufacture data and the operational data. Another method includes controlling a pulse-width modulated (PWM) motor control signal, receiving data regarding an interaction between the blade and a tissue clamped by the anvil, and adjusting a frequency of the PWM signal based on the data related to the interaction.

Abstract: A method for authenticating the compatibility of a staple cartridge with a surgical instrument is disclosed. The method can comprise inserting a staple cartridge into a surgical instrument, receiving a first signal from a first RFID tag on a first component of the staple cartridge with an RFID reader system, receiving a second signal from a second RFID tag on a second component of the staple cartridge with the RFID reader system, comparing the first signal and the second signal to stored data for a compatible staple cartridge, and locking a staple firing system of the surgical instrument if the first signal and the second signal do not match the stored data for a compatible staple cartridge.

Abstract: A surgical instrument includes a body, a shaft, a motor, a firing assembly, an end effector, and a control circuit. The motor is activatable to actuate the firing assembly through a firing stroke to staple and sever tissue with the end effector. The control circuit is configured to monitor one or more use metrics of the surgical instrument. Responsive to at least one of the one or more use metrics exceeding a predetermined threshold, the control circuit is further configured to initiate at least one of providing a notification to a user or disabling the firing assembly.

Abstract: A surgical instrument comprising an articulatable end effector and an articulation control system is disclosed. The articulation control system comprises actuators that, when actuated, cause the end effector to articulate in predetermined directions. When the end effector is rotated downwardly, the articulation control system flips, or switches, the response to the inputs from the actuators.
