The stapler (2) includes a handle assembly (4) and a shaft (8) extending distally from the handle assembly (4). A tool assembly (10) is configured to selectively couple to the shaft (8) and includes a cartridge assembly (16) and an anvil assembly (18). The cartridge assembly (16) includes a staple guide (17) defining a tissue contacting surface (22). A resilient member (20) operably positioned within the cartridge assembly (16) is configured to bias the staple guide (17) distally to provide a predetermined compressive force against tissue when the cartridge assembly (16) and anvil (18) are approximated toward one another.2/3 Ac C14 M C14 C14 U-> C14 rC14 C14 C 3 cv,> I cn J, If
