8. Surgical apparatus according to claim 7, further comprising override means operatively connected to said locking means for permitting said jaw elements to open when the surgical incision member is not secured in either of said jaw elements.

9. Surgical apparatus according to claim 7, wherein said receiving means comprises a first recess in each said jaw element.

10. Surgical apparatus according to claim 7, further comprising the surgical incision member, said surgical incision member having two pointed ends, both ends engageable with said securing means.

11. Surgical apparatus according to claim 7, wherein said securing means comprises a slidable elongated member engageable with the surgical incision member.

12. Surgical apparatus according to claim 7, further comprising control means positioned at a proximal end of said body portion for moving said jaw elements, wherein said control means moves in the same plane as said jaw elements.

13. Surgical apparatus according to claim 12 wherein said control means is rotatably attached to said body portion.

14. Surgical apparatus for manipulating a surgical incision member comprising

an elongated body portion defining a longitudinal axis;

first and second jaw elements extending from said body portion, at least one of said jaw elements being movable between an open and closed position, each of said jaw elements having a first recess;

a surgical incision member comprising a needle pointed at two ends, both ends supported by one of said first and second jaw elements in said first recess;

at least one elongated member engageable with said needle pointed at two ends and movable between a first position to secure said needle and a second position to release said needle; and

a handle mechanism positioned at a distal end of said body portion for moving said jaw elements, said handle mechanism including two arms moveable toward the longitudinal axis defined by said elongated body portion.

15. Surgical apparatus for manipulating a surgical incision member comprising

an elongated body portion defining a longitudinal axis;
