Abstract
Abstract A hand instrument and method for use by a surgeon to target the appropriate entry point and trajectory on bony tissue through which an instrument, such as a nail, pin, screw, rod, wire, drill bit, or other implant is passed. Imbedded within the instrument is at least one relatively radio-opaque target which allows the user to predict with the use of an x-ray or fluoroscopic imaging device the placement of said instrument or implant before drilling it into place with the use of an x-ray or fluoroscopic imaging device. By manipulating the device around the axis of the guide piece, the surgeon can predict the placement of the instrument or implant without iterative insertion and removal of the instrument or implant itself.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
76 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and more than one arm member fixed to said body, each arm member containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway.
Claim 2
Dependent Claim
76 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and more than one arm member fixed to said body, each arm member containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway.
Claim 3
Dependent Claim
23 words
The device of claim 1 wherein said targeting device has two arm members disposed from each other approximately 90° apart about said axis.
Claim 4
Dependent Claim
112 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body wherein said targeting device has two relatively radio-opaque target markers extending at least partially from one end of said targeting member toward the opposite end of said targeting member; and a substantially open gap in the targeting member between each of said target markers wherein said target markers establish a plane that is coplanar with an axis of said passageway.
Claim 5
Dependent Claim
112 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body wherein said targeting device has two relatively radio-opaque target markers extending at least partially from one end of said targeting member toward the opposite end of said targeting member; and a substantially open gap in the targeting member between each of said target markers wherein said target markers establish a plane that is coplanar with an axis of said passageway.
Claim 6
Dependent Claim
92 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body and containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway wherein said targeting device has at least one area of said targeting member coated with a contrast medium.
Claim 7
Dependent Claim
92 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body and containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway wherein said targeting device has at least one area of said targeting member coated with a contrast medium.
Claim 8
Dependent Claim
146 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body and containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway; wherein said targeting device has an angle guide with a front angled portion and a rear portion comprising at least part of said body of said targeting device and configured and dimensioned to be secured to bony surface; and wherein said angle guide has teeth which are broader at the base of said teeth than at the apex of said teeth and are on said front angled portion of the angle guide.
Claim 9
Dependent Claim
146 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body and containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway; wherein said targeting device has an angle guide with a front angled portion and a rear portion comprising at least part of said body of said targeting device and configured and dimensioned to be secured to bony surface; and wherein said angle guide has teeth which are broader at the base of said teeth than at the apex of said teeth and are on said front angled portion of the angle guide.
Claim 10
Dependent Claim
128 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body and containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway wherein at least one relatively radio-opaque target marker has at least two substantially perpendicular sections; at least one first section extending distally from a point proximal one end of said targeting member toward the opposite end; and at least one second section substantially perpendicular to the first section and extending toward a bony target.
Claim 11
Dependent Claim
128 words
An orthopedic targeting device for the placement of an instrument in a desired position relative to a bony target using an imaging device, said device comprising: a body of said targeting device defining a guide passageway through which said instrument is passed; and at least one targeting member fixed to said body and containing at least one relatively radio-opaque target marker that establishes a plane that is coplanar with an axis of said passageway wherein at least one relatively radio-opaque target marker has at least two substantially perpendicular sections; at least one first section extending distally from a point proximal one end of said targeting member toward the opposite end; and at least one second section substantially perpendicular to the first section and extending toward a bony target.
