Abstract

Apparatus comprising drill guide bodies and a pair of positioning bars, each such drill guide body being a body so configured and constructed as to define an imaginary axis through the length thereof and forming a pilot guide bore for guiding a drill substantially along said axis and at least one lateral bore substantially perpendicular to said pilot guide bore substantially along chord of said drill guide body disposed on opposite sides of the pilot guide bore, and methods of forming stents and rigid guides for guiding the drilling of holes into a patient'"'"'s boney structure are disclosed.

Claims

rigidifying means for making the stent rigid for fixedly positioning, spacing and orienting the drill guide bodies to guide a drill through the respective drill guide bodies at a predetermined orientation to a predetermined location in a patient'"'"'s boney structure.

4. A stent for forming a guide shaped as the reciprocal replication of the surface of a portion of a patient'"'"'s boney structure into which holes are to be drilled at predetermined locations, spacing and orientation, comprising, in combination:

a plurality of drill guide bodies, each such drill guide body being a generally cylindrical elongate body having first and second ends, a length and a diameter, the length being at least about twice as great as the diameter, said body being so configured and constructed as to define an imaginary axis generally centrally through the length thereof and being configured and constructed to define a pilot guide bore substantially along said axis for guiding a drill during use and also being configured and constructed to define through the elongate generally cylindrical body between said first and second ends at least one lateral bore oriented substantially perpendicular to said pilot guide bore and passing through the body substantially along chord of said body disposed on one side of the pilot guide bore;

a guide bar constructed and configured to fit snugly in the lateral bores in the drill guide bodies extending through the lateral bore of said drill guide bodies for securing said drill guide bodies together to permit the drill guide bodies to be position and spaced relative to each other and to permit the drill guide bodies to be axially oriented relative to each other; and

rigidifying means for making the stent rigid for fixedly positioning, spacing and orienting the drill guide bodies to guide a drill through the respective drill guide bodies at a predetermined orientation to a predetermined location in a patient'"'"'s boney structure.

5. A method for forming a stent for a rigid guide having a surface that is a reciprocal replication of the surface of a portion of a patient'"'"'s boney structure into which holes are to be drilled at predetermined locations, spacing and orientation, comprising:

fitting a plurality of drill guide bodies onto at least one positioning bar, each such drill guide body being a generally cylindrical elongate body having first and second ends, a length and a diameter, the length being at least about twice as great as the diameter, said body being so configured and constructed as to define an imaginary axis generally centrally through the length thereof and being configured and constructed to define a pilot guide bore substantially along said axis for guiding a drill during use and also being configured and constructed to define through the elongate generally cylindrical body between said first and second ends at least one lateral bore oriented substantially perpendicular to said pilot guide bore and passing through the body substantially along chord of said body disposed on one side of the pilot guide bore, the positioning bar being configured to fit snugly in the lateral bores in the drill guide bodies extending through the lateral bores of said drill guide bodies for securing said drill guide bodies together to permit the drill guide bodies to be position and spaced relative to each other and to permit the drill guide bodies to be axially oriented relative to each other; and
