Abstract

A surgical aiming system is disclosed comprising a one or more fixation plates, an aiming assembly, a one or more nails and a plurality of screws. Said aiming assembly comprising a channeling assembly and a plurality of channels. Said one or more fixation plates comprising a plurality of plate apertures capable of receiving a portion of said plurality of screws. Said plurality of channels in said aiming assembly are capable of aligning a portion of said plurality of screws with said plurality of plate apertures in a first fixation plate. Said plurality of channels receive and align said plurality of screws as they are secured to said first bone. Said first fixation plate being extramedullary attached to a portion of said surface of said first bone; and said plurality of channels of said aiming assembly being aligned to identify a one or more intramedullary locations within said first bone.

Claims (57)

1. A surgical aiming system comprising:

a one or more fixation plates, an aiming assembly, a one or more nails and a plurality of screws;

said one or more fixation plates comprising a first fixation plate;

said aiming assembly comprising a channeling assembly and a plurality of channels;

said one or more fixation plates comprising a plurality of plate apertures capable of receiving a portion of said plurality of screws;

said plurality of channels in said aiming assembly are capable of aligning a portion of said plurality of screws with said plurality of plate apertures in said first fixation plate;

said first fixation plate having

a first end,

a second end,

a top surface, and

a bottom surface;

said plurality of plate apertures comprising a first plate aperture and a second first plate aperture;

said channeling assembly having

a thickness,

a top surface, and

a bottom surface;

said bottom surface of said first fixation plate substantially configured to couple with a surface of a first bone of a skeletal system;

said bottom surface of said aiming assembly substantially couples with said top surface of said first fixation plate;

said plurality of channels receive and align said plurality of screws as said plurality of screws are inserted through said plurality of plate apertures and configured to be secured to said first bone;

said first fixation plate being extramedullary attached to a portion of said surface of said first bone;

said plurality of channels of said aiming assembly being aligned to identify a one or more intramedullary locations including

an entry point for said one or more nails, and

an alignment and entry point for each among said plurality of plate apertures;

said aiming assembly comprising an assembly of a plurality of components;

said aiming assembly comprising a channeling assembly and an intramedullary entry locator having a pointing device;

said one or more nails comprising a first nail;

said intramedullary entry locator having an upper portion and a lower portion;

said upper portion comprising a first channel and a second channel of said intramedullary entry locator;

said lower portion comprising said pointing device;

said upper portion being capable of releasably attaching to said channeling assembly of said aiming assembly;

said upper portion being substantially parallel with said channeling assembly of said aiming assembly when attached thereto; and

said lower portion bending down and away from said upper portion until said pointing device is substantially perpendicular to said upper portion.

2. A surgical aiming system comprising: a one or more fixation plates, an aiming assembly, a one or more nails and a plurality of screws; said one or more fixation plates comprising a first fixation plate; said aiming assembly comprising a channeling assembly and a plurality of channels; said one or more fixation plates comprising a plurality of plate apertures capable of receiving a portion of said plurality of screws; said plurality of channels in said aiming assembly are capable of aligning a portion of said plurality of screws with said plurality of plate apertures in said first fixation plate; said first fixation plate having a first end, a second end, a top surface, and a bottom surface; said plurality of plate apertures comprising a first plate aperture and a second first plate aperture; said channeling assembly having a thickness, a top surface, and a bottom surface; said bottom surface of said first fixation plate substantially configured to couple with a surface of a first bone of a skeletal system; said bottom surface said aiming assembly substantially couples with said top surface of said first fixation plate; said plurality of channels receive and align said plurality of screws as said plurality of screws are inserted through said plurality of plate apertures and configured to be secured to said first bone; said first fixation plate being extramedullary attached to a portion of said surface of said first bone; and said plurality of channels of said aiming assembly being aligned to identify a one or more intramedullary locations including an entry point for said one or more nails, and an alignment and entry point for each among said plurality of plate apertures, wherein said aiming assembly comprising an assembly of a plurality of components; and said aiming assembly comprising a channeling assembly and an intramedullary entry locator having a pointing device, wherein said one or more nails comprising a first nail; said intramedullary entry locator having an upper portion and a lower portion; said upper portion comprising a first channel and a second channel of said intramedullary entry locator; said lower portion comprising said pointing device; and said upper portion being capable of releasably attaching to said channeling assembly of said aiming assembly, wherein said first nail comprising a plurality of threaded female apertures; said aiming assembly comprising a triangular screw guide;

said triangular screw guide comprising a plurality of channels; said triangular screw guide is capable of releasably attaching to said first nail; with said triangular screw guide attached to said first nail, said plurality of channels in said triangular screw guide are aligned with said plurality of threaded female apertures of said first nail; and aligning a portion of said plurality of screws with said plurality of threaded female apertures comprises attaching said portion of said plurality of screws into said first bone through said plurality of channels of said triangular screw guide.

3. The surgical aiming system of claim 2 wherein:

said aiming assembly comprising a one-piece component.

4. The surgical aiming system of claim 2 wherein:

said upper portion being substantially parallel with said channeling assembly of said aiming assembly when attached thereto; and

said lower portion bending down and away from said upper portion until said pointing device is substantially perpendicular to said upper portion.

5. The surgical aiming system of claim 2 wherein:

said pointing device identifying said entry point for said first nail or drill when said upper portion is attached to said channeling assembly; and

said entry point aligned so that said first nail can enter said first bone without hitting said plurality of screws within said first bone.

6. The surgical aiming system of claim 2 wherein:

said first bone of said skeletal system belongs to a mammal.

7. The surgical aiming system of claim 2 wherein:

said first bone of said skeletal system belongs to a human.

8. The surgical aiming system of claim 2 further comprising:

said one or more plates comprising of said first fixation plate a supplementary plate;

said one or more plates attach around a portion of said first bone;

said one or more plates each comprise a portion of said plurality of plate apertures;

said aiming assembly releasably attaches to said one or more plates;

said plurality of channels in said aiming assembly align and direct said plurality of screws into and through said plurality of plate apertures in said one or more plates; and
