Abstract: A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.

Abstract: An adapter assembly of a surgical instrument includes a cam member defining a proximal cam slot and a distal cam slot, a first articulation shaft, and a second articulation shaft. The first articulation shaft has a proximal end portion received in the proximal cam slot, and a distal end portion configured to be coupled to a surgical loading unit. The second articulation shaft has a proximal end portion received in the distal cam slot, and a distal end portion configured to be coupled to the surgical loading unit. The first and second articulation shafts are configured to move in opposing longitudinal directions in response to a rotation of the cam member to articulate the surgical loading unit.

Abstract: A surgical stapling device is provided and includes a handle assembly and a tubular body portion supported on a distal end of the handle assembly having a staple cartridge assembly containing a plurality of surgical staples in an annular array. An anvil assembly is at a distal end of the stapling device and has a shaft for removably connecting the anvil assembly to the tubular body portion. The anvil assembly and tubular body portion are juxtaposed with respect to one another along the shaft and are arranged so as to be approximated with respect to one another. A support member extends from the tubular body portion towards the anvil assembly and a buttress material is supported by the support member and removably attached to the support member where the buttress material is disposed between the anvil assembly and the staple cartridge assembly.

Abstract: A staple cartridge includes a cartridge body and a plurality of staples. The cartridge body defines a plurality of rows of staple pockets and a central knife slot. One of the staples is received in each of the staple pockets. Each of the staples defines a burr or facet that faces the central knife slot and defines a plane that is substantially parallel to the longitudinal axis of the cartridge body.

Abstract: An apparatus for joining two hollow organ sections includes a staple cartridge component, an anvil component, a knife member, a buttress mount and a buttress member. The staple cartridge component includes a plurality of surgical staples in an annular array. The anvil component is movable relative to the staple cartridge component between spaced apart and approximated positions to adjustably clamp tissue. The knife member is movable relative to the staple cartridge component. The buttress mount is concentrically disposed at least partially within the lumen of the knife member. The buttress mount includes a plurality of spokes radially extending outward and a plurality of legs detachably secured with an inner wall of the knife member. The buttress member is secured with the plurality of spokes of the buttress mount. The buttress member is concentrically aligned with the plurality of surgical staples.

Abstract: A surgical stapling apparatus includes a tool assembly, at least one surgical buttress, and a resilient, porous material. The tool assembly includes a cartridge assembly and an anvil assembly pivotably coupled to the cartridge assembly. The cartridge assembly includes a first tissue facing surface defining staple retaining slots. The anvil assembly includes a second tissue facing surface defining staple pockets for forming staples expelled from the staple retaining slots of the cartridge assembly. The at least one surgical buttress is releasably disposed on at least one of the first and second tissue facing surfaces. The resilient, porous material is releasably disposable between the first and second tissue facing surfaces and in contact with the at least one surgical buttress. The resilient, porous material is configured to expel a liquid therefrom upon compression thereof by an approximation of the cartridge assembly and the anvil assembly.

Abstract: A surgical buttress for use in a surgical stapling apparatus is provided and includes an elongate rectangular body portion defining a width; a neck portion integrally formed with and extending from a distal end of the body portion, the neck portion defining a width; a head portion integrally formed with and connected to a distal end of the neck portion, the head portion defining a width; and a tail portion integrally formed with and extending from a proximal end of the body portion, the tail portion defining a width. The width of the tail portion is less than the width of the body portion.
