Abstract: A method of controlling motor velocity in a surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a control circuit coupled to the motor, a position sensor coupled to the control circuit, and a timer coupled to the control circuit. The method includes receiving a first position of a displacement member from a position sensor, starting a timer, advancing the displacement member to a second position by setting a motor velocity to a first velocity, receiving the second positon from the position sensor, stopping the timer when the displacement member reaches the second position, receiving elapsed time from the timer, wherein the elapsed time is the time taken by the displacement to move from the first position to the second positon, and controlling, by the control circuit, velocity of the motor based on the elapsed time.

Abstract: A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.

Abstract: In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

Abstract: A surgical instrument with a tissue-clamping end effector, where actuation of the instrument is locked out when the thickness of the tissue clamped in the end effector is not within a specified thickness range. The end effector may comprise a tissue thickness module that senses the thickness of the tissue clamped in the end effector. The surgical instrument also comprises a control circuit in communication with the tissue thickness module. The control circuit prevents actuation of a working portion of the end effector when the thickness of the tissue clamped in the end effector is not within the specified thickness range.

Abstract: An apparatus includes a shaft assembly and an end effector. The shaft assembly includes an outer sheath and a staple driving mechanism. The end effector includes a staple deck, an anvil, a first staple driver, and a second staple driver. The staple deck defines a plurality of staple openings in at least one annular array. Each staple opening in the plurality of staple openings houses a staple. The anvil is configured to actuate relative to the staple deck to compress tissue between the staple deck and the anvil. The staple driving mechanism is configured to actuate the first staple driver to fire a first staple of the plurality of staples against the anvil. The staple driving mechanism is further configured to actuate the second staple driver independently of the first staple driver to fire a second staple of the plurality of staples against the anvil.
