A system for stapling tissue, comprising: a stapling head including first and second jaws movable with respect to one another between a tissue receiving configuration and a tissue stapling configuration, the first jaw including a stapling mechanism and the second jaw including a staple forming su
1. A system for stapling tissue, comprising: a stapling head including first and second jaws movable with respect to one another between a tissue receiving configuration and a tissue stapling configuration, the first jaw including a stapling mechanism and the second jaw including a staple forming surface, the stapling head further including gross and fine movement mechanisms controlling gross and fine movements, respectively, of one of the first and second jaws relative to the other of the first and second jaws; anda control unit including a first actuator controlling the gross and fine movement mechanisms and a second actuator operating the stapling mechanism. 2. The system according to claim 1, wherein the fine movement mechanism includes a clamp received around the first and second jaws, wherein the first actuator controls proximal and distal movement of the clamp for controlling fine movement of the first and second jaws. 3. The system according to claim 2, wherein the clamp is substantially C-shaped. 4. The system according to claim 1, wherein the gross movement mechanism includes a cable fixed at a first end to the first jaw, threaded around a spindle in the second jaw and fixed at a second end to the first actuator. 5. The system according to claim 1, wherein the stapling mechanism includes stapling slots arranged in a row extending from a proximal end to a distal end of the first jaw, each of the stapling slots including a staple. 6. The system according to claim 5, wherein the first jaw includes a staple pusher driving staples in the stapling slots successively against the staple forming surface of the second jaw as the staple pusher moves from the proximal end toward the distal end of the first jaw. 7. The system according to claim 6, wherein the stapling head further defines a first surface which, when in the tissue stapling configuration, abuts target tissue, and wherein the stapling head includes a tissue cutter cutting on a side of the stapling head opposite the first surface. 8. The system according to claim 7, wherein the tissue cutter is disposed on a proximal end of the staple pusher. 9. The system according to claim 6, wherein the stapling mechanism includes further stapling slots arranged in a further row substantially parallel to the row of the stapling slots. 10. The system according to claim 9, wherein the tissue cutter cuts tissue between the row and the further row. 11. A system for stapling tissue, comprising: a stapling head including first and second jaws movable with respect to one another between a tissue receiving configuration and a tissue stapling configuration, the first jaw including a stapling mechanism and the second jaw including a staple foaming surface, the stapling head further including gross and fine movement mechanisms altering a distance between the first and second jaws;a control unit including a first actuator controlling the gross and fine movement mechanisms and a second actuator operating the stapling mechanism; anda flexible shaft coupling the control unit to the stapling head. 12. The system according to claim 11, wherein the flexible shaft includes a drive cable having a first end coupled to the first actuator and a second end coupled to the fine movement mechanism. 13. The system according to claim 12, wherein the stapling head includes a translation arrangement translating rotation of the drive cable into linear movement of a clamp received around the first and second jaws. 14. The system according to claim 13, wherein the clamp is substantially C-shaped. 15. The system according to claim 11, wherein the flexible shaft includes an actuation cable having a first end coupled to the first actuator and a second end coupled to the gross movement mechanism. 16. The system according to claim 15, wherein the actuation cable is fixed at the second end to the first jaw and threaded around a spindle in the second jaw, wherein the first actuator controls a proximal force applied to the cable for controlling gross movement of the first and second jaws.
