Adapter assemblies for surgical device

An articulation assembly for use with a surgical device, the articulation assembly comprising:

• a first articulation member disposed in mechanical cooperation with an end effector assembly of the surgical device;
• a second articulation member disposed in mechanical cooperation with the end effector assembly of the surgical device;
• a first spring-loaded articulation mechanism disposed in mechanical cooperation with the first articulation member, the first spring-loaded articulation mechanism including a first distal linkage, a first stop member, and a first biasing member, the first biasing member disposed between the first distal linkage and the first stop member;
• and
• a second spring-loaded articulation mechanism disposed in mechanical cooperation with the second articulation member, the second spring-loaded articulation mechanism including a second distal linkage, a second stop member, and a second biasing member, the second biasing member disposed between the second distal linkage and the second stop member,
• wherein distal movement of the first articulation member relative to the first stop member results in the first biasing member moving toward an expanded orientation.

A surgical device, comprising:

• an end effector including a surgical tool;
• an outer tube having a distal end, the end effector pivotably connected to the distal end of the outer tube;
• and
• an articulation assembly including:
• a first articulation member disposed in mechanical cooperation with the end effector assembly;
• a second articulation member disposed in mechanical cooperation with the end effector assembly;
• a first spring-loaded articulation mechanism disposed in mechanical cooperation with the first articulation member, the first spring-loaded articulation mechanism including a first distal linkage, a first stop member, and a first biasing member, the first biasing member disposed between the first distal linkage and the first stop member;
• and
• a second spring-loaded articulation mechanism disposed in mechanical cooperation with the second articulation member, the second spring-loaded articulation mechanism including a second distal linkage, a second stop member, and a second biasing member, the second biasing member disposed between the second distal linkage and the second stop member,
• wherein distal movement of the first articulation member relative to the first stop member results in the first biasing member moving toward an expanded orientation.
