    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: A surgical instrument configured for use in a surgical procedure is disclosed herein. The surgical instrument comprises a housing, a first sensor configured to detect a condition of the surgical instrument, and a second sensor configured to detect the condition of the surgical instrument. The surgical instrument further comprises a processor, wherein the processor is located within the housing. The first sensor and the second sensor are in signal communication with the processor. The processor receives a first signal from the first sensor and a second signal from the second sensor. The processor is configured to utilize the first signal and the second signal to determine the condition and communicate instructions to the surgical instrument during the surgical procedure in view of the condition.

    Abstract: A surgical instrument comprising a controller, a staple firing system, and an RFID system is disclosed. The controller is in communication with a first RFID reader and a second RFID reader of the RFID system and the staple firing system. In various embodiments, the controller verifies the presence of the staple cartridge in the surgical instrument upon receiving the first signal from the first RFID tag. Also, in various embodiments, the controller verifies that the staple cartridge is an unfired staple cartridge upon receiving the second signal from the second RFID tag. The controller can also be configured to track the progress of the staple firing stroke through the RFID system.

    Abstract: A method is provided for operating a powered surgical stapler having a motor unit, a controller, and a stapling assembly having a plurality of movable members that are actuatable longitudinally by the motor unit to clamp, staple, and cut tissue. The controller determines that a movable member of the stapling assembly is in a first predetermined position, and then executes an actuation algorithm to activate the motor unit to actuate the movable member longitudinally from the first predetermined position toward a second predetermined position. The controller observes an actual longitudinal displacement of the movable member between the first and second predetermined positions. The controller compares the actual longitudinal displacement to an expected longitudinal displacement and determines that the actual longitudinal displacement differs from the expected longitudinal displacement by a difference value. The controller then adjusts the actuation algorithm based on the difference value.
