ABSTRACT:
A fast closure mechanism for a linear surgical stapling device as described. This comprises a double four-bar linkage which operates to both place a retaining pin into an anvil and properly and quickly approximate the staple cartridge to the anvil. Thereafter, a gap-setting screw is used so that the proper gap is set between the anvil and the cartridge. Firing is accomplished only after the gap is properly set and within the appropriate gap described pre-determined for the instrument. After firing, opening of the stapler may be accomplished with a similar fast opening motion.
