Tissue thickness compensator comprising resilient members

摘要

A tissue thickness compensator comprising at least one woven lattice can be positioned in the end effector of a surgical instrument. A fastener cartridge that is positioned in the end effector can comprise at least one cavity configured to receive a fastener. The fastener can be moveable between an initial position, wherein the fastener is at least partially position in a cavity, and a fired position, wherein the fastener is configured to compress a woven lattice of the tissue thickness compensator. The woven lattice can comprise a resilient material such that compression of the woven lattice generates a restoring force. The woven lattice can also comprise an axis that can laterally traverse the fastener cartridge, diagonally traverse the fastener cartridge, or intersect a deck surface of the fastener cartridge. The woven lattice can comprise a hydrophilic substance, which can expand when the woven lattice is severed by a cutting element.

主权项

1. A fastener cartridge assembly for a surgical instrument, the fastener cartridge assembly comprising:
a cartridge body defining a longitudinal axis, wherein said cartridge body comprises fastener cavities; an array of discrete woven lattices extending across said longitudinal axis of said cartridge body, wherein each said discrete woven lattice is connected to said array, wherein said discrete woven lattices are arranged longitudinally along said longitudinal axis, and wherein said woven lattices comprise a resilient material; and a fastener moveable between an initial position and a fired position, wherein said fastener is at least partially positioned in a said fastener cavity when said fastener is in said initial position, and wherein said fastener is configured to compress at least one woven lattice when said fastener is moved to said fired position.
