An end effector (16) for use with a surgical instrument comprising an anvil shaft (34), a first anvil assembly (30) disposed at a distal portion of the anvil shaft and a second anvil assembly (32) mountable on the anvil shaft proximally of the first anvil assembly. Also, a method for performing a surgical procedure is provided including the steps of providing a surgical instrument including a first cartridge assembly (28) and a first anvil assembly (30) having an anvil shaft (34), approximating the first anvil assembly and first cartridge assembly and ejecting staples (74) from the first cartridge assembly. The method further includes removing the first cartridge assembly from the tubular organ, and inserting a second anvil assembly (32) into the tubular organ to engage the anvil shaft of the first anvil assembly and ejecting staples (174) from a second cartridge assembly (128) towards the second anvil assembly. |
