Abstract
A linear surgical stapling instrument includes a magazine for holding a plurality of undeformed surgical staples, and an upper jaw carrying the magazine and having opposed distal and proximal ends. An anvil is formed with staple-deforming pockets, and a lower jaw carries the anvil. In particular the lower jaw is formed as a channel defined by an inverted U-shaped cross section. The anvil is formed on the outer surface of the back of the U-shaped cross section with the staple deforming pockets stamped or punched therein. Accordingly, the lower jaw can be easily made of metal with known metal-forming techniques, and stamping or punching techniques. In addition, the configuration of the low jaw causes it to resist bending and twisting during the staple deforming operation.
