The surgical stapling apparatus includes a handle assembly, an elongated body extending distally from the handle assembly, and an articulation mechanism for articulating a tool assembly. The articulation mechanism includes a first gear rotatably mounted on a transmission shaft and configured to engage a second gear, a clutch interconnecting the second gear and a main shaft; and a yoke shaft coupled to the main shaft and adapted to linearly advance a J-channel, the J-channel operatively connected to an articulation link. A motor assembly may rotate the transmission shaft of the articulation mechanism. Alternatively, the articulation mechanism may include an articulation knob. Users may manually rotate the articulation knob to articulate the tool assembly of the surgical stapling apparatus.
1.

1. A method of manipulating a tool assembly of a surgical apparatus, the method comprising the steps of: rotating an articulation knob to disengage a clutch and rotate a main shaft;transferring rotation of the main shaft to a yoke shaft;moving a pin within a slot on a frame to cause translation of the frame due to the rotation of the yoke shaft; andadvancing an articulation link axially to articulate the tool assembly from the translation of the frame. 2. The method of claim 1, further comprising the step of: alerting a user that the clutch is disengaged. 3. The method of claim 1, wherein the clutch is disengaged to prevent back driving of a motor assembly. 4. The method of claim 1, wherein the frame defines a J-channel. 5. The method of claim 1, wherein the step of rotating the articulation knob allows a user to use the tool assembly in a manual mode. 6. The method of claim 1, further comprising the step of: rotating the articulation knob to engage the clutch and operate in a powered mode, wherein a motor assembly rotates the main shaft via a first gear and a second gear. 7. A method of manipulating a tool assembly of a surgical apparatus, the method comprising the steps of: operating the tool assembly in a manual mode by rotating an articulation knob to disengage a clutch and rotate a main shaft; andoperating the tool assembly in a powered mode, wherein a motor assembly rotates the main shaft. 8. The method of claim 7, wherein the main shaft is rotated by the motor assembly when the motor assembly rotates a first gear and a second gear with the second gear attached to the clutch and main shaft. 9. The method of claim 8, further comprising the step of: rotating a transmission shaft to articulate the tool assembly, wherein the first gear is rotatably mounted on the transmission shaft and is configured to engage the motor assembly. 10. The method of claim 8, wherein a rotational speed of the main shaft is reduced using the second gear interposed between the motor assembly and the first gear. 11. The method of claim 8, further comprising the step of: transferring rotation of the second gear to the main shaft. 12. The method of claim 7, further comprising the steps of: transferring rotation of the main shaft to a yoke shaft; moving a pin within a slot on a frame to cause translation of the frame due to the rotation of the yoke shaft; andadvancing an articulation link axially to articulate the tool assembly from the translation of the frame. 13. The method of claim 7, further comprising the step of: alerting a user that the clutch is disengaged. 14. The method of claim 7, wherein the clutch is disengaged to prevent back driving of a motor assembly. 15. The method of claim 7, wherein the frame defines a J-channel.
