    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.

    Abstract: An apparatus includes a body, a shaft extending distally from the body, a motor, a stapling assembly disposed at a distal end of the shaft, and a timer circuit operatively coupled to the motor and the firing actuator. The body includes a firing actuator and the motor is configured to activate in response to a firing actuation of the firing actuator. The motor is further configured to deactivate after a first predetermined time period subsequent to the firing actuation. The stapling assembly is configured to selectively move from an open position to a closed position to clamp tissue and is operable to drive a plurality of staples into the clamped tissue in response to activation of the motor. The timer circuit is configured to activate a timer in response to the firing actuation. The timer is configured to run for a second predetermined time period. The timer circuit is configured to ensure deactivation of the motor upon expiration of the second predetermined time period.

    Abstract: A method of adjusting velocity in a motorized surgical instrument is provided. The surgical instrument comprises a displacement member configured to translate within the surgical instrument over a plurality of predefined zones, a motor coupled to the displacement member to translate the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, the position sensor configured to measure the position of the displacement member and a timer circuit coupled to the control circuit, the timer circuit configured to measure elapsed time. The method includes setting a directed velocity of the displacement member; determining an actual velocity of the displacement member; determining an error between the directed velocity of the displacement member and the actual velocity of the displacement member; and controlling the actual velocity of the displacement member based on the magnitude of the error.
