The invention discloses a kind of tissue thickness compensation part, it includes can be positioned at least one braiding lattice stride in the end effector of surgical instruments.The fastener cartridge being positioned in end effector may include at least one cavity that can receive fastener.The fastener can be moved between initial position and firing position, and fastener is positioned at least partially in cavity described in the initial position, and fastener can compress the braiding lattice stride of the tissue thickness compensation part described in the firing position.The braiding lattice stride may include a kind of elastomeric material so that the compression of braiding lattice stride produces restoring force.The braiding lattice stride may also include axis, and the axis can laterally traverse the fastener cartridge, diagonally traverse the fastener cartridge or intersect with the platform surface of the fastener cartridge.The braiding lattice stride may include hydroaropic substance, and when the braiding lattice stride is cut element cut-out, described kind of hydroaropic substance may expand. |
