Surgical stapling device with reload assembly removal lockout

An adapter assembly comprising:

• a firing rod including a proximal portion and a distal portion, the firing rod movable between retracted and advanced positions;
• an articulation assembly including an articulation lever, a coupling member, and an articulation link, the coupling member operatively coupled to the articulation lever and to the articulation link, the articulation lever rotatable to move the coupling member longitudinally between a neutral position and non-neutral positions to move the articulation link between advanced and retracted positions;
• a release mechanism movable from a locked position to an unlocked position;
• and
• a lockout movable from an unlocked position to a locked position in response to movement of the coupling member from the neutral position to one of the non-neutral positions and/or in response to movement of the firing rod from the retracted position towards the advanced position, the lockout configured to prevent movement of the release mechanism from its locked position to its unlocked position when the lockout is in its locked position;
• wherein the lockout includes a body having a first protrusion and a second protrusion, the coupling member of the articulation assembly defines a first notch, and the firing rod defines a second notch, the first protrusion positioned within the first notch when the coupling member is in the neutral position, and the second protrusion positioned within the second notch when the firing rod is in the retracted position.

A surgical stapling device comprising:

• a reload assembly including a proximal body and a tool assembly, the proximal body defining a first longitudinal axis, the tool assembly pivotably coupled to the proximal body by a pivot member, the pivot member defining an articulation axis that is transverse to the first longitudinal axis, the tool assembly including a cartridge assembly and an anvil, the proximal body including a drive assembly and a first articulation link, the first articulation link having a proximal portion and a distal portion, the distal portion of the first articulation link coupled to the tool assembly such that movement of the first articulation link causes articulation of the tool assembly about the articulation axis between a non-articulated position and articulated positions, the drive assembly movable between a drive retracted position and a drive advanced position to actuate the tool assembly;
• and
• an adapter assembly defining a second longitudinal axis and having a distal portion releasably coupled to the reload assembly, the adapter assembly including:
• a firing rod having a proximal portion and a distal portion, the distal portion of the firing rod adapted to be coupled to the drive assembly of the reload assembly when the reload assembly is coupled to the adapter assembly, the firing rod movable between a rod retracted position and a rod advanced position to move the drive assembly of the reload assembly between the drive retracted position and the drive advanced position to actuate the tool assembly;
• an articulation assembly including an articulation lever, a coupling member, and a second articulation link, the coupling member operatively coupled to the articulation lever and to the first articulation link, the articulation lever rotatable to move the coupling member longitudinally between a neutral position and non-neutral positions to move the first articulation link between a link advanced position and a link retracted position, the second articulation link being adapted to be coupled to the first articulation link when the reload assembly is coupled to the adapter assembly such that longitudinal movement of the second articulation link causes longitudinal movement of the first articulation link to articulate the tool assembly about the articulation axis;
• a release mechanism movable from a release locked position to a release unlocked position, wherein in the release locked position, the release mechanism prevents the reload assembly from being uncoupled from the adapter assembly;
• and
• a lockout movable from a lockout unlocked position to a lockout locked position in response to movement of the coupling member from the neutral position to one of the non-neutral positions and movable from the lockout unlocked position to the lockout locked position in response to movement of the firing rod from the rod retracted position towards the rod advanced position, the lockout configured to prevent movement of the release mechanism from the release locked position to the release unlocked position when the lockout is in the lockout locked position.
