Abstract

A vise for clamping and firmly holding allograph in place includes three adjustments which are accessible to the operating room staff from and within the sterile surgical field. The first adjustment includes a clamp to clamp the invention onto the standard operating room table. This first adjustment includes a clamp tightening handle and pivoting underside clamping surface which enables the vise to be mounted onto the operating table and secured onto the table by manipulations from above the surface of the operating room table and therefore, within the sterile field. The second adjustment includes an additional adjusting handle for angularly positioning the vise grip. The third adjustment includes another adjusting handle for opening and closing the vise. A variety of special purpose face plates for the two elements of the vise are provided to accommodate different surgical requirements. These face plates are removably inserted into the elements of the vise.

Claims

1. An allograft vise comprising:

first and second vise gripping plates, means connected to said vise plates for moving said plates relative to each other and vary the distance between said plates;

means connected to said vise plates for angularly adjusting the plane of said vise plates;

clamping means connected to said angularly adjusting means for clamping said vise to a support surface, said means for moving said vise plates including a first manually rotatable handle, and rotatable threaded means connected to said first manually rotatable handle and to at least one of said vise plates whereby rotation of said handle causes rotation of said threaded means and movement of said vise plate;

said means for angularly adjusting said vise plates including a first swivel support extending from one of said vise plates, first adjustable means connected to said swivel support for permitting said swivel support to rotate and a second manually rotatable handle connected to said first adjustable means for tightening and loosening said first adjustable means;

said clamping means including a second support connected to said means for angularly adjusting said vise plates and a clamping surface adjustably coupled to said second support surface for clamping said vise to a working surface located between said second support surface and said clamping surface, said clamping surface being connected to a rotatable clamping surface support pivotally mounted for bringing said clamping surface into and out of engagement with said working surface;

a third adjustable handle connected to said support surface and to said rotatable clamping surface support for adjusting the clamping force exerted by said clamping surface on said working surface.

2. The allograft vise of claim 1 wherein said vise gripping plates include respective removeable inserts, one of said inserts having a roughened flat surface and the other of said inserts having a notched surface for firmly supporting allograph in said notch.

3. The allograft vise of claim 1 wherein said vise gripping plates include respective removeable inserts, one of said inserts having an angularly extending pointed rod formed thereon and the other of said inserts having a pair of angularly extending pointed rods extending therefrom, said rods each extending towards each other for forming a tripod support for firmly supporting allograph between the ends of said rods.

4. The allograft vise of claim 1 wherein said first, second and third manually adjustable handles are all located within the sterile surgical field above a plane of said working surface.

6. The vise of claim 1 wherein said rotatable clamping support and said third adjustable handle are pivotally mounted in a pair of parallel rails and further including a bar means connected to said support surface pivotally mounted in said parallel rails at a position between said rotatable clamping support and said third adjustable handle for permitting the forces exerted by said third adjustable handle to be transmitted to said clamping surface.

5. An allograft vise comprising:

first and second vise gripping plates, means connected to said vise plates for moving said plates relative to each other to vary the distance between said plates;

means connected to said vise plates for angularly adjusting the plane of said vise plates;

clamping means connected to said angularly adjusting means for clamping said vise to a support surface said clamping means being adjustable from above said support.

7. An allograft vise comprising:

first and second vise gripping plates, means connected to said vise plates for moving said plates relative to each other to vary the distance between said plates;

means connected to said vise plates for angularly adjusting the plane of said vise plates;

clamping means connected to said angularly adjusting means for clamping said vise to a support surface said clamping means being adjustable from above said support surface;

said clamping means including first and second clamping surfaces, said first clamping surface contacting the upper side of said support surface and said second clamping surface contacting the lower side of said support surface, means connected to said second clamping surface for pivoting said second clamping surface into and out of a position for engagement with said lower side of said support surface by contacting a portion of said support surface when said clamping means is being affixed to said support surface;

connecting means connected to and pivotally mounting said second clamping surface;

support bar means connected to said first clamping surface said bar means being pivotally mounted in said connecting means and adjustment handle means pivotally mounted in said connecting means for adjusting the clamping forces on said second clamping surface.

8. In an allograft vise for use in operating room surgical procedures having first and second vise gripping plates, means connected to said vise plates for moving said plates relative to each other and to vary the distance between said plates;

means connected to said vise plates for angularly adjusting the plane of said vise plates;

clamping means connected to said angularly adjusting means for clamping said vise to a support surface;

the improvement comprising mounting means in at least one of said vise gripping plates for removably mounting an insert said mounting means including a first swivel support extending from said vise plate for supporting said insert and permitting said insert to rotate to compensate for allograph of differing configuration.

9. An allograft vise comprising:

first and second vise gripping plates, means connected to said vise plates for moving said plates relative to each other and vary the distance between said plates;

means connected to said vise plates for angularly adjusting the plane of said vise plates;

said angular adjusting means including a manually rotatable handle connected to said angular adjusting means for tightening and loosening said angular adjusting means;

at least two clamping means connected to said handle for holding said angular adjusting means in a desired position;

serrated anchoring means connected to said clamping means for holding said clamping means in the desired position, all of said foregoing means being formed of sterilizable materials.
