5. The clip of claim 4 wherein the ratchet engagement permits movement of the first jaw towards the second jaw to a set position and prevents movement of the first jaw away from the second jaw from the set position with the first support being axially aligned with the second support and the third support being axially aligned with the fourth support.

6. The clip of claim 5 wherein the ratchet engagement permits movement of the first jaw away from the second jaw with the first support being pivoted relative to the second support and the third support being pivoted relative to the fourth support.

7. The clip of claim 1 wherein the first support has an inner hollow portion and a projection extending from the inner hollow portion and the second support has teeth extending laterally from the second support to correspondingly engage with the projection of the first support.

8. The clip of claim 7 wherein the inner hollow portion is configured to substantially enclose the second support, the second support being slidable within the inner portion of the first support.

9. The clip of claim 6 wherein the ratchet engagement permits incremental movement in a first direction while the first support is axially aligned with the second support.

10. The clip of claim 9 wherein the ratchet engagement permits free movement in a second direction opposite the first direction when the second support is out of alignment with the second support.

11. The clip of claim 1 further comprising a pin extending through apertures in the first and second supports and a pin slot extending axially along the first and second supports.

12. A surgical guide clip comprising:

a first jaw having a first end, a second end and a tissue contacting surface extending from the first end to the second end;

a second jaw having a first end, a second end and a tissue contacting surface extending from the first end to the second end, the first jaw and the second jaw movable between a spaced position and a proximate position;

a first connector coupled to the first end of the first jaw and the first end of the second jaw and having a first projection operatively engageable with a second projection to regulate movement of the first jaw and second jaw between the spaced and proximate position; and

a second connector coupled to the second end of the first jaw and the second end of the second jaw.

13. The clip of claim 12 wherein the first connector further comprises a first support having a proximal end coupled to the first end of the first jaw and a distal end and a second support having a distal end coupled to the first end of the second jaw and a proximal end coupled to the distal end of the first support.

14. The clip of claim 13 wherein the second connector further comprises a third support coupled to the first jaw and a fourth support coupled to the second jaw, the third and fourth supports being generally parallel to the first and second supports and the first and third supports being movable a predetermined distance in a predetermined direction, as the first and second jaws are moved towards the proximate position.

15. The clip of claim 14 further comprising a first pin and a first pin slot and wherein the first support extends orthogonally from the first jaw and the distal end of the first support is connected to the second support extending orthogonally from the second jaw by the first pin slidably and pivotably connected to the first pin slot extending along the second support.

16. The clip of claim 15 wherein the first support has an interior portion and the second support slides within the interior portion as the first and second jaws are moved to the proximate position;

and wherein the first projection extends laterally from a first wall of the interior portion and the second projection extends laterally from a first wall of the second support, the first projection extending towards the first wall of the second support and the second projection extending towards the first wall of the first support with the first and second jaws in a set position.

17. The clip of claim 16 wherein the first support has a second wall on the opposing side of the first support relative to the first wall and the second support has a second wall on the opposing side of the second support relative to the first wall, the second wall of the first support and the second wall of the second support operatively in contacting with each other when the first projection and the second projection operatively disengage from each other.

18. The clip of claim 12 wherein the first connector has a first hinge point pivotably coupling the first end of the second jaw to the first end of the first jaw and the second connector has a second hinge point pivotably coupling the second end of the second jaw to the second end of the first jaw.

19. The clip of claim 12 wherein the first and second connectors are symmetrical and have pivot pins disposed through pivot slots in each connector pivotably coupling the first jaw to the second jaw to allow opening of the jaws to the spaced position by allowing the first and second jaws to pivot in a direction opposite of the first direction.

20. The clip of claim 19 wherein the pivot slot has a width and length sized and configured to accommodate sufficient pivoting of the first and second jaws to disengage the first projection from the second projection.
