Abstract

A flexible surgical screw retainer and method for holding a surgical screw within a sterilizable package and dispensing the screw in a controlled manner at a selected site. The retainer has an elongated recess into which a surgical screw may be placed in order to be retained by frictional engagement with the side walls of the recess. The recess is sized to any of a variety of screw sizes. When the package is opened, the surgical screw retainer may be removed and grasped by a user and squeezed in order to disengage the screw from the recess and enable it to fall to a selected surface.

Claims

1. In combination, an elongated surgical screw and a retainer for holding said elongated surgical screw comprising:

a flexible body having a top surface, a bottom surface and a pair of opposed end surfaces;

an elongated screw-receiving recess formed in said top surface in alignment between said opposed end surfaces, said recess having a predetermined width sufficient to frictionally engage said surgical screw;

means for enabling said recess to be manually deformed by squeezing said opposed ends together to thereby automatically decrease the frictional engagement of said screw and eject said screw from said recess.

2. A combination according to claim 1 wherein said elongated surgical screw has an axis and a maximum predetermined diameter and wherein said elongated screw-receiving recess has a floor at a predetermined depth sufficient to enable said recess to receive and hold said surgical screw therein such that the distance between said top surface and said floor is greater than or equal to one-half said predetermined diameter.

3. A combination according to claim 1 wherein said elongated screw-receiving recess has an axis, which is transverse to said opposed end surfaces.

4. A combination according to claim 1 wherein said means for enabling comprises inclined opposed end surfaces, inclined symmetrically relative to the axis of said elongated screw receiving means.

5. A package comprising:

an elongated surgical screw;

a flexible retainer block having a top surface, a bottom surface and a pair of opposed, symmetrically tapered end surfaces;

an elongated screw-receiving recess formed in said top surface in alignment between said opposed end surfaces, said recess containing said surgical screw and having a predetermined width sufficient to frictionally engage said surgical screw;

a sterilizable housing containing said surgical screw and said flexible retainer block.

6. A system of packaging surgical screws of varying diameters and lengths comprising:

a surgical screw having a length and width;

a resilient retainer for holding said surgical screw, said retainer comprising a top surface, a bottom surface and a pair of opposed, symmetrically tapered end surfaces, an elongated screw-receiving recess formed in said top surface in alignment between said opposed end surfaces, said recess for containing said surgical screw and having a predetermined size sufficient to frictionally engage said surgical screw;

a container for holding said resilient retainer;

a cover means for closing said container.

7. A method of packaging a surgical screw comprising the steps of:

providing an elongated surgical screw;

providing a flexible retainer having a top surface, a bottom surface and a pair of opposed, symmetrically tapered end surfaces, an elongated screw-receiving recess formed in said top surface in alignment between said opposed end surfaces, said recess for containing said surgical screw and having a predetermined width sufficient to frictionally engage said surgical screw;

placing said surgical screw in said recess to form thereby a screw/retainer assembly;

placing said screw/retainer assembly in a housing;

sealing said housing with a removable lid.

8. A method according to claim 7 wherein said step of placing said screw/retainer assembly in a housing further comprises placing said recess facing away from said lid.

9. A method of removing an elongated surgical screw having an axis from a package containing the screw comprising the steps of:

providing a package comprising a sealed housing containing an assembly of a flexible retainer and a surgical screw frictionally retained within said flexible retainer, said flexible retainer having a pair of opposed, user-engageable, symmetrically tapered end surfaces situated transversely to the axis of said surgical screw, said housing being sealed with a removable lid;

opening the package by removing said lid to provide access to said assembly;

grasping said assembly by engaging said pair of opposed, user-engageable end surfaces with opposed fingers;

squeezing said user-engageable end surfaces together to thereby, automatically release said surgical screw.

10. A method of using a surgical object retainer comprising the steps of:

providing an elongated surgical object;

providing a flexible retainer having a top surface, a bottom surface and a pair of opposed, symmetrically tapered end surfaces, an elongated object-receiving recess formed in said top surface in alignment between said opposed end surfaces, said recess for containing said surgical object and having a predetermined width sufficient to frictionally engage said surgical object;

placing said surgical object in said recess to form thereby an object/retainer assembly;

placing said object/retainer assembly in a housing;

sealing said housing with a removable lid;

removing said removable lid;

grasping said assembly by engaging said pair of opposed, user-engageable end surfaces with opposed fingers;

squeezing said user-engageable end surfaces together to thereby, automatically release said surgical object.
