Abstract

A method for manipulating tissue of a patient includes a surgical instrument having a handle assembly, a shaft assembly, and an end effector. The method includes positioning a tissue within a gap between a cartridge and an anvil and against a guide pin to laterally position the tissue relative to the cartridge and the anvil. The method also includes moving a retaining pin from an open position to a closed position to capture the tissue and moving the cartridge toward the anvil in a closed configuration. Furthermore, the method includes inhibiting deflection of a distal end portion of the end effector wherein at least at least one of the guide pin or the retaining pin connects to the distal end portion. The method further includes forming a plurality of staples within the tissue and cutting the tissue with a knife.
