Abstract

A staple instrument includes a staple holder comprising a pair of jaws, a drive shaft, a rotational handle, and a coupling to convert rotational motion of the handle into axial advancement of the shaft. A distal end of the shaft cooperates with the staple holder to cause three-point bending of a staple bridge to thereby open the legs of the staple.

First claim

The invention claimed is:

1 . A staple instrument comprising
a staple holder comprising a pair of jaws; a drive shaft; a rotational handle; a coupling to convert rotational motion of the handle into axial advancement of the shaft; a distal end of the shaft positioned to cooperate with the jaws of the staple holder for causing three-point bending of a staple bridge; said coupling including a cam surface cooperating with a cam driver.

2 . A staple instrument according to claim 1 , the cam surface being disposed on a proximal end of the shaft and the cam driver being disposed on a distal handle end.

3 . A staple instrument according to claim 2 , the cam surface including a loading region separated by a hump from an operating region.

4 . A kit comprising the staple instrument of claim 1 and a staple.

5 . The kit of claim 4 , said staple instrument and said staple being disposed within a container.

6 . The kit of claim 4 , a distal end of the shaft having a contoured end shaped to retain a bridge of the staple.

7 . The kit of claim 4 , the staple being loaded on said staple holder with each jaw angle ranging from 80° to less than 90°.
