Abstract

A surgical instrument includes an end effector, a firing member movable distally to effect a firing motion at the end effector, wherein the firing member comprises a cam slot, and a lockout pawl. The lockout pawl has a cam feature receivable in the cam slot, wherein the cam slot is configured to guide the cam feature to cause a rotation of the lockout pawl between a first position where the lockout pawl permits the distal movement of the firing member, and a second position where the lockout pawl prevents the distal movement of the firing member.
