Surgical staple actuating sled with actuation stroke having minimized distance relative to distal staple

摘要

A surgical instrument includes an end effector with a staple cartridge. The staple cartridge includes a deck, a terminal driver assembly, and a wedge sled. The terminal driver assembly is positioned adjacent to a distal tip of the staple cartridge. The terminal driver assembly is configured to receive a first terminal portion of staples in the staple cartridge. The terminal driver assembly at least partially defines a storage space therebelow within jaw of the end effector. The wedge sled is configured to longitudinally slide proximate to the deck and engage the terminal driver assembly and force the terminal portion of the plurality of staples toward the anvil for formation in tissue. At least a majority of the wedge sled is configured to fit within the storage space and not slide distally beyond the terminal driver assembly when the wedge sled is in the distal sled position.
