Abstract
An apparatus includes a body assembly, a shaft, an end effector, and a cartridge. The end effector includes a jaw, a pivotable anvil, and a knife member. The cartridge includes a deck, a buttress assembly, and a folding sled. A first portion of the buttress assembly is positioned on top of the deck. A second portion of the buttress assembly is positioned within the longitudinal channel. The folding sled is configured to translate within the longitudinal channel to move the second portion of the buttress assembly to a position that is above the deck in response to actuation of the knife member. The second portion of the buttress assembly is thereby secured against edges of tissue severed by the knife member.
Claims20
An apparatus, the apparatus comprising:
- (a) a body assembly;
- (b) a shaft extending distally from the body assembly;
- (c) an end effector attached to the shaft, wherein the end effector comprises:
- (i) a jaw,
- (ii) an anvil pivotable from an open position to a closed position relative to the jaw, and
- (iii) a knife member configured to translate relative to the anvil in order to sever tissue;
- and
- (d) a cartridge defining a longitudinal channel, wherein the knife member is configured to translate within the longitudinal channel, wherein the cartridge comprises:

- (i) a jaw,
- (ii) an anvil pivotable from an open position to a closed position relative to the jaw,
- (iii) a knife member configured to translate relative to the anvil in order to sever tissue, and
- (iv) a wedge sled configured to translate with the knife member;
- and
- (d) a cartridge defining a longitudinal channel, wherein the knife member is configured to translate within the longitudinal channel, wherein the cartridge comprises:
- (i) a deck comprising an upper surface facing toward the anvil in the closed position,
- (ii) a plurality of staple pockets,
- (iii) a plurality of staples located within the plurality of staple pockets, the wedge sled is operable to drive the plurality of staples out of the plurality of staple pockets,
- (iv) a buttress assembly, wherein a first portion of the buttress assembly is positioned on top of the deck, wherein a second portion of the buttress assembly is positioned within the longitudinal channel, and
- (v) a folding sled configured to translate within the longitudinal channel to move the second portion of the buttress assembly to a position that is above the deck.
An apparatus, the apparatus comprising:
- (a) a body assembly;
- (b) a shaft extending distally from the body assembly;
- (c) an end effector attached to the shaft, wherein the end effector comprises:
- (i) a jaw,
- (ii) an anvil pivotable from an open position to a closed position relative to the jaw, and
- (iii) a knife member configured to translate relative to the anvil in order to sever tissue;
- and
- (d) a cartridge releasably engaged with the jaw, wherein the cartridge defines a longitudinal channel, wherein the knife member is configured to translate within the longitudinal channel, wherein the cartridge comprises:
- (i) a deck comprising an upper surface facing toward the anvil,
