Abstract
A surgical stapling device includes a staple reload and a shipping wedge. In embodiments, the shipping wedge is configured to disable the use of a staple reload if the staple reload does not have an actuation sled. In other embodiments, the actuation sled includes a readable identifier that facilitates confirmation of the presence of an actuation sled within a staple reload from a location externally of the staple reload.

(canceled)
A surgical stapling device comprising:
- a body portion supporting a drive assembly including a knife bar;
- a tool assembly supported on the body portion and including an anvil and a cartridge assembly coupled to the anvil such that the tool assembly is movable between an open position and a clamped position, the cartridge assembly including a channel and a staple cartridge positioned within the channel, the channel including a wall defining a longitudinal slot that facilitates passage of the knife bar, the staple cartridge including staples and configured to receive an actuation sled, the knife bar movable through the tool assembly from a retracted position to an advanced position;
- a shipping wedge releasably coupled to the stapling device, the shipping wedge including a body portion, a retaining member, and a detection member, the retaining member extending through the longitudinal slot in the channel of the cartridge assembly to secure the shipping wedge to the stapling device, the retaining member movable within the longitudinal slot of the channel from a locked position in which the retaining member is locked within the longitudinal slot to an unlocked position in which the retaining member is removable from the longitudinal slot, the detection member supported on the body for movement between first and second positions, the detection member extending into the tool assembly into engagement with the actuation sled when the actuation sled is present in the staple cartridge to move the detection member from the second position to the first position, wherein in the second position, the detection member is positioned to prevent movement of the retaining member from the locked position to the unlocked position.
A shipping wedge configured to be releasably coupled to a tool assembly of a stapling device, the shipping wedge comprising:
- a body having a proximal portion and a distal portion;
- a retaining member supported on the body, the retaining member positioned to extend through a longitudinal slot in a channel of the tool assembly to secure the shipping wedge to the stapling device, the retaining member movable within the longitudinal slot of the channel from a locked position in which the retaining member is locked within the longitudinal slot to an unlocked position in which the retaining member is removable from the longitudinal slot;
- and
- a detection member supported on the body for movement between first and second positions, wherein in the second position, the detection member is positioned adjacent the retaining member to obstruct movement of the retaining member from the locked position to the unlocked position, and in the first position, the detection member is positioned to facilitate movement of the retaining member from the locked position to the unlocked position.
A surgical stapling device comprising;
- a staple reload including a tool assembly and a body portion, the tool assembly supported on the body portion of the staple reload and including an anvil and a cartridge assembly coupled to the anvil such that the tool assembly is movable between an open position and a clamped position, the cartridge assembly including a channel and a staple cartridge positioned within the channel, the channel including a wall defining a longitudinal slot, the staple cartridge including staples and configured to receive an actuation sled;
- a shipping wedge releasably coupled to the stapling device, the shipping wedge including a body, a retaining member, and a detection member, the retaining member extending through the longitudinal slot in the channel of the cartridge assembly to secure the shipping wedge to the stapling device, the retaining member movable within the longitudinal slot of the channel from a locked position in which the retaining member is locked within the longitudinal slot of the channel to an unlocked position in which the retaining member is removable from the longitudinal slot of the channel, the detection member supported on the body of the shipping wedge and movable between first and second positions, the detection member extending into the tool assembly into engagement with the actuation sled when the actuation sled is present in the staple cartridge and the shipping wedge is coupled to the stapling device to move the detection member from the second position to the first position, wherein in the second position, the detection member is positioned to prevent movement of the retaining member from the locked position to the unlocked position.
