Dual-sided reinforced reload for surgical instruments

A buttress applier cartridge configured to interface with an end effector of a surgical stapling instrument, wherein the buttress applier cartridge comprises:

• a first loading region configured to interface with an anvil of the end effector, wherein the first loading region comprises:
• a first absorbable layer;
• and
• a loading assembly for securing the first absorbable layer to the anvil as the anvil approaches the first absorbable layer;
• a suture supporting the first absorbable layer, wherein the loading assembly is configured to couple the suture to the anvil;
• wherein the loading assembly comprises a suture applier rotatable relative to the first absorbable layer between a resting position and an actuated position, and wherein the suture applier is configured to rotate toward the actuated position as the anvil approaches the first absorbable layer;
• and
• a second loading region configured to interface with an elongate channel of the end effector, wherein the second loading region comprises:
• a staple cartridge removably coupled to the buttress applier cartridge, wherein the staple cartridge comprises a deck;
• and
• a second absorbable layer positioned on the deck.

A buttress applier cartridge configured to interface with an end effector of a surgical stapling instrument, the buttress applier cartridge being generally U-shaped defining an open end and a closed end, wherein the buttress applier cartridge comprises:

• a first loading region within the u-shape of the buttress applier cartridge configured to interface with an anvil of the end effector at the open end of the buttress applier cartridge, wherein the first loading region comprises:
• a first absorbable layer;
• and
• a loading assembly for securing the first absorbable layer to the anvil as the anvil approaches the first absorbable layer;
• and
• a second loading region within the u-shape of the buttress applier cartridge configured to interface with an elongate channel of the end effector at the open end of the buttress applier cartridge, wherein the second loading region comprises:
• a staple cartridge removably coupled to the buttress applier cartridge, wherein the staple cartridge comprises a deck;
• and
• a second absorbable layer positioned on the deck,
• wherein the second loading region comprises a latch configured to removably couple the staple cartridge to the buttress applier cartridge.

A buttress applier cartridge configured to interface with an end effector of a surgical stapling instrument, the buttress applier cartridge being generally U-shaped defining an open end and a closed end, wherein the buttress applier cartridge comprises:

• a buttress loading zone within the u-shape of the buttress applier cartridge configured to interface with an anvil of the end effector at the open end of the buttress applier cartridge, wherein the buttress loading zone comprises:
• a first buttress layer;
• a suture supporting the first buttress layer;
• and
• a loading assembly for securing the suture to an outer surface of the anvil as the anvil approaches the first buttress layer;
• and
• a cartridge loading zone within the u-shape of the buttress applier cartridge configured to interface with an elongate channel of the end effector at the open end of the buttress applier cartridge, wherein the cartridge loading zone comprises:
• a staple cartridge removably coupled to the buttress applier cartridge, wherein the staple cartridge comprises a deck;
• and
• a second buttress layer positioned on the deck, wherein the staple cartridge is secured by the cartridge loading region at a position where the second buttress layer is intermediate the first buttress layer and the deck of the staple cartridge prior to seating the staple cartridge in the elongate channel of the end effector.

A buttress applier cartridge configured to interface with an end effector of a surgical stapling instrument, the buttress applier cartridge being generally U-shaped defining an open end and a closed end, wherein the buttress applier cartridge comprises:

• a first loading region within the u-shape of the buttress applier cartridge sized to receive an anvil of the end effector at the open end of the buttress applier cartridge;
• a first absorbable layer positioned in the first loading region;
• a tether positioned to secure the first absorbable layer to the anvil when the anvil is positioned in the first loading region and engaged with the first absorbable layer;
• a second loading region within the u-shape of the buttress applier cartridge sized to receive an elongate channel of the end effector at the open end of the buttress applier cartridge;
• a second absorbable layer positioned in the second loading region;
• and
• a staple cartridge removably secured to the buttress applier cartridge in the second loading region, the staple cartridge comprising a staple cartridge connector sized and shaped to cooperate with an elongate channel connector to secure the staple cartridge to the end effector, with the staple cartridge secured in the second loading region, the staple cartridge connector free of connection to the elongate channel connector and thereby available for securement to the elongate channel connector.
