A surgical instrument for surgically joining tissue is disclosed. The instrument comprises a handle assembly, an elongated portion, an end effector, and an articulation mechanism. The elongated portion extends distally from the handle assembly. The end effector is disposed adjacent a distal portion of the elongated portion. The articulation mechanism is disposed in mechanical cooperation with the end effector for articulating the end effector. The articulation mechanism comprises a lever, a knob, a plate and a lower clutch. The plate is disposed at least partially within a portion of the knob. The lower clutch is disposed in mechanical engagement with the plate. The plate is disposed at least partially between the lower clutch and the knob. The lower clutch is keyed to the plate to limit rotation therebetween. The lower clutch is keyed to the knob to limit rotation therebetween.
1. A surgical instrument for surgically joining tissue, the surgical instrument comprising: a handle assembly;an elongated portion extending distally from the handle assembly and defining a first longitudinal axis;an end effector disposed adjacent a distal portion of the elongated portion, the end e
1. A surgical instrument for surgically joining tissue, the surgical instrument comprising: a handle assembly;an elongated portion extending distally from the handle assembly and defining a first longitudinal axis;an end effector disposed adjacent a distal portion of the elongated portion, the end effector defining a second longitudinal axis; andan articulation mechanism disposed in mechanical cooperation with the end effector for moving the end effector between a first position where the first longitudinal axis is aligned with the second longitudinal axis and a second position where the first longitudinal axis is disposed at an angle with respect to the second longitudinal axis, the articulation mechanism comprising: a lever;a housing;a plate disposed at least partially within a portion of the housing; anda lower clutch disposed in mechanical engagement with the plate and movable with respect to the plate,wherein at least a portion of the plate is disposed between the lower clutch and at least a portion of the housing, wherein the lower clutch is keyed to the plate via four keys to limit rotation therebetween, and wherein the lower clutch is keyed to the housing to limit rotation therebetween. 2. The surgical instrument of claim 1, wherein the plate is rotatable with respect to the housing. 3. The surgical instrument of claim 1, wherein the lower clutch is keyed to the housing via two keys. 4. The surgical instrument of claim 3, wherein the two keys used to key the lower clutch to the housing are also used to key the lower clutch to the plate. 5. The surgical instrument of claim 1, further comprising a cover disposed in contact with the lever, a biasing element disposed in mechanical cooperation with the cover, and an upper clutch disposed in mechanical cooperation with the lower clutch and in mechanical cooperation with the biasing element. 6. The surgical instrument of claim 5, where the articulation mechanism further includes a knob disposed in mechanical engagement with the lower clutch, wherein a distance the upper clutch can move with respect to the knob is a distance “a,” wherein a radial edge of the cover is spaced from the lever a distance “b,” wherein the lower clutch is keyed to the housing via at least one key, the at least one key having a distance “c” disposed in the same direction as the distances “a” and “b,” and wherein the distance “c” is greater than the distance “a” plus the distance “b”. 7. The surgical instrument of claim 5, further comprising a drive element disposed in mechanical cooperation with the housing, a shaft of the drive element extends through an aperture of the plate and through an aperture of the lower clutch, the shaft is mechanically coupled to the upper clutch and the lever. 8. The surgical instrument of claim 7, further comprising an articulation shaft disposed in mechanical cooperation with the drive element, such that rotation of the drive element causes longitudinal translation of the articulation shaft. 9. An articulation mechanism for use with a surgical instrument, the articulation mechanism comprising: a lever;a knob;a lower clutch disposed in mechanical engagement with the knob;a cover disposed in contact with the lever;a biasing element disposed in mechanical cooperation with the cover; andan upper clutch disposed in mechanical cooperation with the lower clutch and in mechanical cooperation with the biasing element;wherein a distance the upper clutch can move with respect to the knob is a distance “a,” wherein a radial edge of the cover is spaced from the lever a distance “b,” wherein the lower clutch is keyed to the knob via at least one key, the at least one key having a distance “c” disposed in the same direction as the distances “a” and “b,” and wherein the distance “c” is greater than the distance “a” plus the distance “b”. 10. The articulation mechanism of claim 9, further comprising a plate disposed between at least a portion of the knob and at least a portion of the lower clutch. 11. The articulation mechanism of claim 10, wherein the lower clutch is keyed to the plate to limit rotation therebetween. 12. The articulation mechanism of claim 10, wherein the plate is rotatable with respect to the knob. 13. The articulation mechanism of claim 10, wherein the lower clutch is keyed to the plate via four keys. 14. The articulation mechanism of claim 9, wherein the lower clutch is keyed to the knob via two keys. 15. The articulation mechanism of claim 14, further comprising a plate, at least a portion of the plate is disposed between at least a portion of the knob and at least a portion of the lower clutch, wherein the two keys used to key the lower clutch to the knob are also used to key the lower clutch to the plate. 16. The articulation mechanism of claim 9, further comprising a drive element disposed in mechanical cooperation with the knob, a shaft of the drive element extends through an aperture of the plate, and the shaft being mechanically coupled to the lever. 17. The articulation mechanism of claim 16, further comprising an articulation shaft disposed in mechanical cooperation with the drive element, wherein rotation of the drive element causes longitudinal translation of the articulation shaft. 18. An articulation mechanism for use with a surgical instrument, the articulation mechanism comprising: a housing;a lower clutch; anda plate disposed between at least a portion of the lower clutch and a portion of the housing, the plate being movable with respect to the lower clutch,wherein the lower clutch is keyed to the plate to limit rotation therebetween, and wherein the lower clutch is keyed to the housing to limit rotation therebetween. 19. A surgical instrument for surgically joining tissue, the surgical instrument comprising: a handle assembly;an elongated portion extending distally from the handle assembly and defining a first longitudinal axis;an end effector disposed adjacent a distal portion of the elongated portion, the end effector defining a second longitudinal axis; andan articulation mechanism disposed in mechanical cooperation with the end effector for moving the end effector between a first position where the first longitudinal axis is aligned with the second longitudinal axis and a second position where the first longitudinal axis is disposed at an angle with respect to the second longitudinal axis, the articulation mechanism comprising: a lever;a housing;a plate disposed at least partially within a portion of the housing; anda lower clutch disposed in mechanical engagement with the plate and movable with respect to the plate,wherein at least a portion of the plate is disposed between the lower clutch and at least a portion of the housing, wherein the lower clutch is keyed to the plate to limit rotation therebetween, and wherein the lower clutch is keyed to the housing via two keys to limit rotation therebetween. 20.
