摘要：
A shaft assembly (2000) is disclosed which comprises an end effector (2300) configurable in an open configuration and a closed configuration, a closure system configured to transition the end effector toward the closed configuration during a closure stroke, a firing member (1500) movable through a firing stroke, and a frame (2200). In various instances, the shaft assembly comprises a first bailout (2800) configured to shift the frame in order to open the end effector and a second, independent, bailout (1700) configured to retract the firing member during and/or after the firing stroke. In certain instances, the closure system is expandable to perform the closure stroke. In at least one such instance, the closure system comprises a proximal portion (3610) mounted to the frame and a distal portion (3630) movable relative to the proximal portion. In at least one instance, the firing member engages the closure member to expand the closure system.
