Abstract
Apparatus for delivering a viscous liquid to a surgical site employs a conventional syringe having a barrel and a plunger movable axially within the barrel from a withdrawn position to an inserted position. The apparatus includes an internally-threaded sleeve and a substantially cylindrical actuation element. The sleeve is configured to receive the plunger in its withdrawn position, and has an open proximal end and a distal end slot configured for receiving the syringe barrel therethrough. The actuation element has an externally-threaded distal portion dimensioned to screw into the proximal end of the sleeve, and a plunger seat, at the distal end of the actuation element, that bears against the plunger and that pushes the plunger axially toward its inserted position in the barrel as the actuation element is threaded into the sleeve.
