A surgical instrument for performing an anastomosis includes a housing having a proximal end and a distal end; a shaft extending from the housing distal end; and a disposable loading unit configured and dimensioned to retain a plurality of surgical fasteners, the disposable loading unit extending from the shaft and forming a juncture with the shaft, the disposable loading unit including: i) opposed split-sections pivotably connected to facilitate movement of the opposed split-sections between open and closed configurations, the opposed split sections being movable through a firing stroke from a first position to a second position and back to the first position to form a plurality of surgical fasteners; and ii) a pivot lockout member including a latch portion which extends between the opposed split-sections, the latch portion including a contact surface which interacts with a corresponding surface formed on at least one of the opposed split-sections to retain the opposed split-sections in the closed configuration, wherein upon return of the fastener pusher member to the first position from the second position, the pivot lockout member is displaced relative to the opposed split sections to an unlocked configuration.
1. A surgical instrument for performing an anastomosis, comprising:a housing having proximal and distal ends; a shaft extending from the distal end of the housing; a firing safety assembly configured to prevent premature firing of the surgical instrument; a disposable loading unit configured for sel
1. A surgical instrument for performing an anastomosis, comprising:a housing having proximal and distal ends; a shaft extending from the distal end of the housing; a firing safety assembly configured to prevent premature firing of the surgical instrument; a disposable loading unit configured for selective attachment to the shaft, the disposable loading unit including: a fastener support member configured and dimensioned to support an array of surgical fasteners; a fastener pusher member being movable so as to deform the array of surgical fasteners; and a lock member configured to removably engage the disposable loading unit relative to the shaft.
