1. A surgical fastener applying apparatus, comprising:
- a cartridge half-section supporting a pair of camming surface extensions extending from a cam bar arrangement;
an anvil half-section, said cartridge and anvil half-sections being relatively movable from an unclamped position to a clamped position;
a first clamp lever operatively connected to the cartridge half-section and a second clamp lever operatively connected to the anvil half-section;
wherein each clamp lever is movable between a first position in which the cartridge and anvil half sections are in the unclamped position, and a second position in which the cartridge and anvil half sections are in the clamped position; and
a pivotably mounted firing lever operatively associated with said pair of camming surface extensions to move said pair of camming surface extensions longitudinally to thereby sequentially fire a plurality of surgical staples in a direction transverse to a direction of travel of said pair of camming surface extensions, wherein the firing lever is pivotable to extend to a right side and left side of the apparatus.

Abstract
The present disclosure relates to surgical fastener applying apparatus for sequentially applying a plurality of surgical fasteners to body tissue. The surgical fastener applying apparatus includes a replaceable cartridge assembly receivable in a distal end portion of a cartridge receiving half-section, the cartridge assembly including a safety lockout pivotably disposed along the upper surface of the cartridge assembly and movable from an unlocked orientation permitting assembly of an anvil half-section to the cartridge receiving half-section, to a locked orientation preventing assembly of the anvil half-section to the cartridge receiving-half section.
