Surgical adhesives mixing and dispensing implement

An apparatus for mixing and dispensing an adhesive having at least two components, comprising:

• a barrel portion having a central longitudinal axis extending therethrough;
• a discharge port at one end of said barrel portion;
• a rotatable screw-shaped mixing element extending through said barrel portion along said central longitudinal axis;
• a dispensing element having a threaded bore selectively operatively engagable with said screw-shaped mixing element for axial movement therealong upon the rotation thereof;
• and
• a means located at an end of said barrel opposite said one end for selectively operatively engaging said dispensing element with said rotatable screw-shaped mixing element affecting axial movement of said dispensing element along said screw-shaped mixing element towards said discharge port.

An apparatus for mixing and dispensing a multi-component adhesive comprising;

• a first barrel of predetermined cross-section having a central longitudinal axis extending therethrough from a first to a second end thereof;
• a second barrel portion fixedly attached to the first end of said first barrel portion and coaxial therewith and having a cross-section larger than the predetermined cross-section of said first barrel portion;
• a rotatable screw-shaped mixing element extending through said barrel along said central longitudinal axis;
• a rotatable drive element sealing the first end of said barrel operatively coupled to said mixing element;
• a dispensing element engagable with and rotatable with said drive element and having a cross-section substantially identical to said predetermined cross-section of said barrel and having a threaded central opening therein receiving and operatively engaging said screw-shaped mixing element, said dispensing element rotatable with said screw-shaped mixing element in a first position within said barrel;
• a means associated with said first end of said barrel for selectively moving said dispensing element out of engagement with said drive element into a second position within said barrel;
• and
• a means for preventing the rotation of said dispensing element when in said second position so that said dispensing element is moved along said mixing element from said first end to said second end of said barrel by the rotation thereof.
