A drive mechanism for use with a surgical instrument includes a rotatable drive member, a crank operatively coupled to the drive member; a clutch operatively coupled to the crank, wherein rotational motion of the drive member causes oscillating movement of the clutch; and a gear rotatably coupled to the clutch, wherein the oscillating movement of the clutch causes rotation of the gear. The drive mechanism may further include a gear configured to engage a linear member. The crank may include a pin extending distally therefrom. The clutch may include a slot dimensioned and configured to receive a pin of the crank.
What it is claimed: 1. A surgical instrument drive mechanism, comprising: a rotatable drive member; a crank operatively connected to the drive member; a clutch operatively coupled to the crank, wherein rotational motion of the drive member causes oscillating movement of the clutch; and a gear rotat
What it is claimed: 1. A surgical instrument drive mechanism, comprising: a rotatable drive member; a crank operatively connected to the drive member; a clutch operatively coupled to the crank, wherein rotational motion of the drive member causes oscillating movement of the clutch; and a gear rotatably coupled to the clutch, wherein the oscillating movement of the clutch causes rotation of the gear. 2. The drive mechanism of claim 1, wherein the gear is configured to engage a linear member to impart axial motion thereto. 3. The drive mechanism of claim 2, wherein the rotary motion of the gear causes distal and proximal axial motion of the linear member when the gear and the linear member are engaged with one another. 4. The drive mechanism of claim 2, wherein an axial motion of the linear member actuates a surgical tool when the gear and the linear member are engaged with one another. 5. The drive mechanism of claim 1, wherein the crank includes a pin extending distally therefrom. 6. The drive mechanism of claim 5 wherein the pin extends from a location offset from a center of the crank. 7. The drive mechanism of claim 5 wherein the clutch includes a slot dimensioned and configured to receive the pin. 8. The drive mechanism of claim 7, wherein the movement of the pin within the slot converts the rotational motion of the drive member into the oscillating motion of the clutch. 9. In a surgical instrument comprising a handle portion, an elongated body portion, and a tool assembly, the improvement comprising: a drive mechanism, including: a rotatable drive member; a crank operatively connected to the drive member; a clutch operatively coupled to the crank, wherein rotational motion of the drive member causes oscillating movement of the clutch; and a gear rotatably coupled to the clutch, wherein the clutch oscillating movement of the clutch causes rotation of the gear. 10. The drive mechanism of claim 9, wherein the gear is configured to engage a linear member to impart linear motion thereto. 11. The drive mechanism of claim 10, wherein the rotary motion of the gear causes distal and proximal axial motion of the linear member when the gear and the linear member are engaged with one another. 12. The drive mechanism of claim 10, wherein an axial motion of the linear member actuates a surgical tool when the gear and the linear member are engaged with one another. 13. The drive mechanism of claim 10, wherein the crank includes a pin extending distally therefrom. 14. The drive mechanism of claim 13, wherein the pin extends from a location offset from a center of the crank. 15. The drive mechanism of claim 13, wherein the clutch includes a slot dimensioned and configured to receive the pin. 16. The drive mechanism of claim 15, wherein the movement of the pin within the slot converts the rotational motion of the drive member into the oscillating motion of the clutch. 17. A method for operating a surgical instrument comprising the steps of: providing a drive mechanism including: a rotatable drive member; a crank operatively connected a the drive member; a clutch coupled to the crank, wherein rotational motion of the drive member causes oscillating movement of the clutch; and a gear rotatably coupled to the clutch, wherein the oscillating movement of the clutch causes rotation of the gear; actuating the drive mechanism; clamping a tissue portion; and fastening the tissue portion. 18. The method of claim 17, further comprising the step of articulating the surgical instrument.
