发明名称 Fluid delivery and bone screw driver apparatus
摘要 A fluid delivery and bone screw driver apparatus attaches to a bone screw. An inner sleeve joins a material delivery source connected to one end of the inner sleeve to the bone screw connected to the other end. A removable liner communicates the material through the inner sleeve and into the bone screw. An outer sleeve seals the outer sleeve to the head of the bone screw. Rotating the outer sleeve tightens the seal and rotates the bone screw.

主权项 1. A fluid delivery and bone screw driver apparatus that attaches to a bone screw, the bone screw having a head with a slotted opening therein and a shaft with a cannula and fenestrations, the apparatus comprising: an outer sleeve having a first proximal end and a first distal end and comprising, external threads near the first distal end;a grasping surface near the first proximal end; an inner shaft extending through the outer sleeve, wherein the inner shaft has a second proximal end and a second distal end and comprises, a coupler at the second proximal end;a counter-torque bar at the second distal end wherein, when engaged with the bone screw head, the counter-torque bar extends radially through the slotted opening in the bone screw head, wherein the counter-torque bar further extends outwardly past the outer sleeve so that it can be manually rotated, and wherein the outer sleeve is independently rotatable around the inner sleeve;a gasket at the distal end; and a removable liner that extends through the proximal end of the inner shaft and out of the distal end of the inner shaft.
