Abstract: A method is provided for operating a powered surgical stapler having a motor unit, a controller. and a stapling assembly having a closure member, a staple driver member, and a knife member. The controller receives a user input that indicates a tissue gap to be defined by the stapling assembly in a closed state. Based on the user input, the controller controls the motor unit to actuate the closure member to transition the stapling assembly to the closed state to define the tissue gap and clamp tissue therein. The controller then controls the motor unit to actuate the staple driver member to drive staples into the clamped tissue. In response to determining that the staple driver member has reached a predetermined longitudinal position, the controller controls the motor unit to initiate actuation of the knife member to cut the clamped tissue.

Abstract: A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member configured to translate over a plurality of predefined zones. A motor comprising a shaft is coupled to the displacement member. A control circuit is coupled to the motor. A position sensor is coupled to the control circuit to monitor the rotation of the shaft. A timer circuit is coupled to the control circuit. The control circuit is configured to receive rotations of the shaft in a current zone defined by a set rotation interval, measure time at a set position of the rotation interval, wherein the measured time is defined as the time taken by the displacement member to traverse the rotation interval based on a predetermined number of shaft rotations, and set a command velocity of the displacement member for a subsequent zone based on the measured time in the current predefined zone.

Abstract: A surgical instrument includes a body assembly, a distally extending shaft assembly, and a distal stapling assembly configured to clamp, staple, and cut tissue. A first user feedback element is configured to visually inform a user of a first condition of the stapling assembly, and a second user feedback element is configured to visually inform the user of a second condition of the stapling assembly. A circuit board assembly includes a circuit board, a first light source configured to illuminate the first user feedback element, a second light source configured to illuminate the second user feedback element, and a light guide feature. The light guide feature is configured to direct light from the second light source toward the second user feedback element and simultaneously inhibit light emitted by the first light source from illuminating the second user feedback element.

Abstract: An apparatus includes a body, a shaft, a stapling assembly, and a sequential logic device. The body includes a safety switch, a firing actuator, and a motor. The stapling assembly is disposed at a distal end of the shaft, wherein the stapling assembly is configured to selectively move from an open position to a closed position to clamp tissue. The sequential logic device is operatively coupled with the motor and configured to detect an actuation of the safety switch and of the firing actuator. The sequential logic device is further operable to detect an order in which the safety switch and the firing actuator are actuated, compare the detected order to a predetermined order, and in response to determining that the detected order is equivalent to the predetermined order, transmit a motor activation signal to the motor.
