Drill pin guide and method for orthopedic surgery

Claim 2

An orthopedic device for setting a bond fragment relative to an adjacent bone mass, said device comprising: a body; a barrel located on and rotatable relative to said body; a first channel through said barrel for accepting a first elongated orthopedic fastening device installed in said bone fragment and for aligning said barrel along said first elongated orthopedic fastening device; and a second channel for laterally spacing a second elongated fastening device from said first elongated orthopedic fastening device and for aligning said second elongated orthopedic fastening device parallel to said first elongated orthopedic fastening device.

Claim 3

The orthopedic device of claim 1 wherein said second channel is sized for accepting a drill bit for boring a socket through said bone fragment and into an adjacent bone mass, said socket for accepting said second device.

Claim 4

The orthopedic device of claim 1 wherein an interference fit is created between said first device and said second device preventing movement of said first device out of said bone fragment and mass when both said devices are installed in said bone fragment and mass.

Claim 5

The device of claim 3 wherein said first device is an orthopedic pin and said second device is an orthopedic screw.

Claim 6

The device of claim 1 wherein said body is cylindrical.

Claim 7

The device of claim 5 wherein said first hole is offset from the longitudinal center line of said body.

Claim 8

The device of claim 6 wherein said second hole is along said longitudinal center line.

Claim 9

A drill pin guide for installing an interlocking pin and screw through a bone fragment and into the underlying bone mass, said guide comprising: a body; a barrel located on and rotatable relative to said body; a first channel through said barrel for accepting a pin installed in said bone fragments; and a second channel through said barrel for accepting a drill bit, for boring a socket through a bond fragment and into an adjacent bone mass; the socket for accepting a screw, said second channel aligned parallel to said first channel and laterally separated from said first channel whereby said screw contacts said pin to prevent outward movement of said pin crating an interference fit between said pin and said screw when said pin and screw are installed.

Claim 10

A drill pin guide for installing an interlocking pin and screw through a bone fragment and into the underlying bone mass, said guide comprising: a body; a barrel located on and rotatable relative to said body; a first channel through said barrel for accepting a pin installed in said bone fragments; and a second channel through said barrel for accepting a drill bit, for boring a socket through a bond fragment and into an adjacent bone mass; the socket for accepting a screw, said second channel aligned parallel to said first channel and laterally separated from said first channel whereby said screw contacts said pin to prevent outward movement of said pin crating an interference fit between said pin and said screw when said pin and screw are installed.

Claim 13

The method of claim 9 wherein the screw has a head and a shaft, the diameter of the head being greater than the diameter of the shaft and whereby the head tangentially contacts the pin causing the interference fit.

Claim 14

The method of claim 10 further comprising the step of bending the pin at the base of the bone before said drilling step.

Claim 15

The method of claim 9 wherein at least one of the threads of the screw tangentially contacts the pin causing the interference fit.

Claim 18

The method of claim 13 further comprising the step of bending the pin at the base of the bone before said drilling step.

Claim 19

The method of claim 13 further comprising the step of placing a guide over the pin before said drilling step, the guide having a first channel for receiving the pin and a second channel for receiving a drill bit, the channels being parallel to each other.

Claim 22

A hole guide for using and stabilizing fractured bones, where such stabilization occurs as a result of a combination of one pin and one or more pins or screws inserted into at least one of said bones, said guide comprising: a body; a barrel having a width and thickness located on and rotatable relative to said body; a first hole through said barrel, said first hole parallel to the axis of said thickness, said hold having a diameter corresponding to the diameter of a first pin used for insertion in at least one of said bones; and a second hole through said barrel, said second hole displaced from said first hole a fixed amount, said second hole substantially parallel to said first hole, said second hole having a diameter corresponding to the diameter of a bit used to construct a hole into at least one of said bones a fixed distance away from said pin.

Claim 23

A hole guide for using and stabilizing fractured bones, where such stabilization occurs as a result of a combination of one pin and one or more pins or screws inserted into at least one of said bones, said guide comprising: a body; a barrel having a width and thickness located on and rotatable relative to said body; a first hole through said barrel, said first hole parallel to the axis of said thickness, said hold having a diameter corresponding to the diameter of a first pin used for insertion in at least one of said bones; and a second hole through said barrel, said second hole displaced from said first hole a fixed amount, said second hole substantially parallel to said first hole, said second hole having a diameter corresponding to the diameter of a bit used to construct a hole into at least one of said bones a fixed distance away from said pin.
