1. A dual action surgical device for reducing a rod into a taper lock screw and locking the rod into position in said screw, the dual action device comprising:
- an elongated central structure having a first end and a second end, said first end having a handle and said second end having at least one screw grasping element;
a rod reducing sleeve circumferentially disposed around a portion of said central structure, said rod reducing sleeve including a rod contact point;
a rod reducing actuator connected to said rod reducing sleeve, said rod reducing actuator being configured to actuate said at least one grasping element to effect the grasping of said screw and position said rod into a rod receiving notch of said screw;
a locking sleeve circumferentially disposed around a portion of said rod reducing sleeve, said locking sleeve including a screw grasping structure; and
a locking actuator connected to said locking sleeve, wherein when said locking actuator is actuated, said grasping structure of said locking sleeve grasps a locking structure on said screw and moves said locking structure into a locked position, independent of the rod reducing sleeve.
