ABSTRACT:
An apparatus and method for joining members together using a self-drilling screw apparatus or stapling apparatus are disclosed. The screw apparatus includes a worm drive screw, a spur gear and superior and inferior screws which turn simultaneously in a bi-directional manner. A rotating mechanism drives the first and second screw members in opposite directions and causes the screw members to embed themselves in the members to be joined. The screw apparatus can be used to join members such as bones, portions of the spinal column, vertebral bodies, wood, building materials, metals, masonry, or plastics. A device employing two screws (two-in-one) can be combined with a capping horizontal mini-plate. A device employing three screws can be combined in enclosures (three-in-one). The stapling apparatus includes grip handles, transmission linkages, a drive rod a fulcrum and a cylinder. The staple has superior and inferior segments with serrated interfaces, a teethed unidirectional locking mechanism and four facet piercing elements. The staples can be also be used to join members such as bones, portions of the spinal column, or vertebral bodies.
