1. A surgical apparatus comprising a tip, the tip having a longitudinal axis, a distal end, and a proximal end, the tip further comprising: a window for receiving tissue;a first wall at a proximal end of the window, the first wall disposed at an angle to the longitudinal axis, the angle selected to impede insertion of the tip into a wound; and,a second wall disposed at an angle to the longitudinal axis at a distal end of the window, further comprising a ferrule holder, the ferrule holder including the second wall, further comprising a tongue extending between the first and second walls, wherein the ferrule holder includes projections receivable within grooves of the tongue for retaining the ferrule holder on the tongue. 2. A surgical apparatus in accordance with claim 1, the surgical apparatus further comprising: an elongate body assembly connecting a body portion to the tongue member, and further comprising first and second elongate needles positioned at least partially within the elongate body assembly, said first needle being longitudinally movable by a first lever and said second needle being longitudinally movable by a second lever. 3. The surgical apparatus of claim 2 wherein said first and said second levers are spaced apart less than 180 degrees from each other. 4. The surgical apparatus of claim 2 wherein said first and said second levers are not diametrically positioned. 5. The surgical apparatus of claim 2 wherein the first and second elongate needles are eccentrically positioned within the elongate body assembly. 6. A surgical apparatus in accordance with claim 1, the surgical apparatus further comprising: a body portion having first and second levers pivotally secured to the body portion, wherein the first lever is a first color to indicate its connection with a first needle, and the second lever is a second color, different than the first color, to indicate its connection with a second needle. 7. A surgical apparatus in accordance with claim 1, the surgical apparatus further comprising a body portion having first and second levers pivotally secured to the body portion, wherein the first and second levers are mounted to a distal end of the body portion. 8. The surgical apparatus of claim 1, further comprising: a body portion having a distal end and a proximal end;a tubular portion having a distal end and a proximal end, the proximal end of the tubular portion attached to the distal end of the body portion, a distal end of the tubular portion positioned proximally of said window; anda lever having a distal end and a proximal end, the distal end of the lever operatively coupled to the distal end of the body portion, wherein the body portion includes a longitudinal axis and the lever includes a longitudinal axis, and further wherein the longitudinal axis of the lever is parallel to the longitudinal axis of the body portion in a closed position of the lever. 9. The surgical apparatus of claim 8 wherein the lever is actuable to a position where the longitudinal axis of the lever is askew from the longitudinal axis of the body portion. 10. The surgical apparatus of claim 1, further comprising: a body portion having a distal end and a proximal end;a tubular portion having a distal end and a proximal end, the proximal end of the tubular portion attached to the distal end of the body portion, a distal end of the tubular portion positioned proximally of said window; and,a lever having a distal end and a proximal end, the distal end of the lever operatively coupled to the distal end of the body portion, wherein the lever is pivotally mounted to the body portion, further comprising a link connected at a first end to the lever and at a second end to a slidable member within the body portion. 11. The surgical apparatus of claim 10 wherein movement of the proximal end of the lever towards the proximal end of the body portion forces the slidable member to move towards the distal end of the body portion. 12. The surgical apparatus of claim 11 further comprising a drive block, wherein the slidable member cooperates with the drive block to move the drive block correspondingly with the slidable member. 13. The surgical apparatus of claim 12 wherein the slidable member is a locking collar which surrounds a reduced diameter portion of the drive block. 14. The surgical apparatus of claim 12 wherein the drive block is biased proximally by a spring. 15. The surgical apparatus of claim 12 wherein the drive block includes a longitudinal opening for frictionally receiving a proximal end of a drive tube. 16. The surgical apparatus of claim 11 wherein the proximal end of the lever is biased away from the proximal end of the body portion. 17. The surgical apparatus of claim 10 wherein movement of the proximal end of the lever away from the proximal end of the body portion forces the slidable member to move towards the distal end of the body portion. 18. The surgical apparatus of claim 17 wherein the slidable member is a needle driver. 19. The surgical apparatus of claim 18 further comprising a needle in the tubular portion, the needle movable in response to movement of the needle driver. 20. The surgical apparatus of claim 18 wherein the lever is a first lever, the link is a first link, and the needle driver is a first needle driver, the surgical apparatus further comprising a second lever having a proximal end and a distal end, the distal end of the second lever operatively coupled to the distal end of the body portion, a second link connected at a first end to the second lever and at a second end to a second needle driver within the body portion. 21. The surgical apparatus of claim 20 wherein the second needle driver is positioned proximal to the first needle driver. 22. The surgical apparatus of claim 21 wherein first needle driver receives a first needle, and the first needle driver has a longitudinal opening dimensioned to allow a second needle to pass through the first needle driver freely to the second needle driver. 23. The surgical apparatus of claim 22 wherein the second needle driver receives the second needle. 24. The surgical apparatus of claim 23 wherein the second needle driver includes an opening dimensioned to frictionally receive the second needle, the opening for receiving the second needle being smaller than the longitudinal opening in the first needle driver for passing the second needle. 25. The surgical apparatus of claim 21 wherein the first needle driver includes another longitudinal opening dimensioned to frictionally receive the first needle, wherein the longitudinal opening receiving the first needle is smaller than the longitudinal opening for passing the second needle. 26. The surgical apparatus of claim 10 wherein the slidable member includes a tab with a hole, the second end of the lever surrounding the tab and connected to the tab via a link pin inserted through the hole and through the second end of the lever. 27. A surgical apparatus in accordance with claim 1, the surgical apparatus further comprising: a body portion having a distal end and a proximal end;a tubular portion having a distal end and a proximal end, the proximal end of the tubular portion attached to the distal end of the body portion; and,a lever having a distal end and a proximal end, the distal end of the lever operatively coupled to the distal end of the body portion, wherein the lever is a first lever, the surgical apparatus further comprising a second lever having a proximal end and a distal end, the distal end of the second lever operatively coupled to the distal end of the body portion. 28. The surgical apparatus of claim 27 wherein the second lever is angularly displaced on the body portion from the first lever. 29. The surgical apparatus of claim 28 wherein the second lever is placed less than 180 degrees from the first lever. 30. The surgical apparatus of claim 27 wherein the first lever includes a first color and the second lever includes a second color, different than the first color. 31. The surgical apparatus of claim 1 wherein the tongue includes a lip which wraps around a distal end of the ferrule holder for further retaining the ferrule holder on the tongue.
