Abstract: An apparatus comprises a body, a shaft assembly, an end effector, a cartridge, and a staple driver actuator. The end effector is operable to manipulate tissue. The end effector comprises a lower jaw, a pivotable anvil, and a translating cutter. The translating cutter is operable to translate relative to the lower jaw and the anvil when the anvil is pivoted toward the lower jaw to manipulate tissue. The cartridge is insertable into the lower jaw and includes a plurality of staples. The staple driver actuator is disposed within the cartridge. The staple driver actuator comprises a secondary cutting element. The translating cutter of the end effector is operable to drive the staple driver actuator distally to staple and cut tissue substantially simultaneously.

Abstract: A surgical instrument includes an end effector, a firing member movable distally from a home position to effect a first firing motion in the end effector, wherein the firing member is movable proximally toward the home position in a return motion, and a lockout pawl. The firing member has a cam slot, a protrusion, and a retaining pocket. The lockout pawl has a cam feature receivable in the cam slot during the return motion, wherein the cam slot is configured to guide the cam feature and move the lockout pawl toward a locking engagement with the protrusion to prevent a second firing motion of the firing member, and wherein the retaining pocket is configured to receive the cam feature to releasably secure the firing member to the lockout pawl when the firing member is in the home position.

Abstract: A surgical end effector includes a cartridge. The cartridge includes first and second sensor arrays disposed in the cartridge. The first sensor array is configured to sense a function of a first component located within the cartridge and the second sensor array is configured to sense a function of a second component located within the cartridge. The first and second sensor arrays are electrically coupled to an electronic circuit. The electronic circuit includes a control circuit configured to receive signal samples from the first sensor array, receive signal samples from the second sensor array, and process the signals samples received from the first and second sensor arrays to determine a status of the cartridge.
