Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
A drill guide for angularly aligning and guiding a drill with respect to an elongated hole in a bone plate, said elongated hole having an inwardly inclined upper camming surface and undercut lower surfaces on the side of the plate to be placed in contact with a bone, said drill guide comprising: an elongated body having at least one hemispherical end surface which bears against the inclined upper surface of said elongated hole and is adapted to be rocked in a plane aligned with the long axis of said plate hole, a guide hole extending through said body which is eccentric to the axis of said body, and a protuberant collar extending from said end surface around the end of said guide hole to form an extension of said guide hole, the walls of said collar being adapted to bear against the undercut surfaces of said plate hole to limit the angular travel of said drill guide when it is rocked in said plate hole.
Claim 2
Dependent Claim
