US Patent:

6520969, Feb 18, 2003

Filed:

Feb 26, 2001

Appl. No.:

09/793167

Inventors:

Greg Lambrecht - Wyckoff NJ
Brett Jason Stern - New York NY
Jacob Einhorn - Washington DC
Kathleen Hydzik Robbins - Brooklyn NY

Assignee:

Stryker Technologies Corporation - Kalamazoo MI

International Classification:

A61B 1900

US Classification:

606130, 606 97

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.
