Abstract
A surgical stapling device includes an adapter assembly and a reload assembly. The adapter assembly includes an elongate body and a channel member coupled to the elongate body. The reload assembly includes an anvil and a cartridge assembly that includes a cartridge body and a channel extension. A proximal portion of the cartridge body is received within the channel member to secure the reload assembly to the adapter assembly. The channel extension is received about a distal portion of the cartridge body and is engaged with the channel member to support the cartridge body.
Claims20
A surgical stapling device comprising:
- an adapter assembly including an elongate body defining a longitudinal axis and having a proximal portion and a distal portion, and a channel member supported on the distal portion of the elongate body, the channel member including a base wall and side walls that define a cavity, the channel member being movable in relation to the elongate body about an axis transverse to the longitudinal axis between a first position aligned with the longitudinal axis and a second position defining an acute angle with respect to the longitudinal axis;
- and
- a reload assembly including an anvil and a cartridge assembly pivotably coupled to the anvil, the cartridge assembly including a cartridge body and a plurality of staples, the cartridge body having a proximal portion and a distal portion and defining a central knife slot and staple pockets positioned on each side of the central knife slot, each of the plurality of staples received within one of the staple pockets, wherein the cartridge body is releasably received within the cavity defined by the channel member to mount the reload assembly to the adapter assembly.
An adapter assembly comprising:
- an elongate body defining a longitudinal axis and having a proximal portion and a distal portion, a mounting assembly, and a channel member supported on the distal portion of the elongate body by the mounting assembly, the channel member including a base wall and side walls that define a cavity configured to receive a cartridge body of a cartridge assembly of a surgical stapling device, the channel member being movable in relation to the elongate body about an axis transverse to the longitudinal axis between a first position aligned with the longitudinal axis and a second position defining an acute angle with respect to the longitudinal axis.
A reload assembly comprising:
- an anvil and a cartridge assembly pivotably coupled to the anvil, the cartridge assembly including a cartridge body, a channel extension and a plurality of staples, the cartridge body having a proximal portion and a distal portion and defining a central knife slot and staple pockets positioned on each side of the central knife slot, each of the plurality of staples received within one of the staple pockets, the channel extension including a base wall and side walls defining a cavity, the cavity receiving the distal portion of the cartridge body, wherein the channel extension is spaced from the proximal portion of the cartridge body.
