Offset alignment device

Abstract

The present invention relates to an offset alignment device that is adjustable in the lateral or medial direction, the anterior or posterior direction and rotatably adjustable at a single interface between the two pieces of the present invention. A first piece is provided having a body with a central axis. A positioner is on the first side of the body. A second piece is provided having a central axis and a flange. A side wall upstands from the flange to define an opening. The positioner can be selectably received within the opening while the central axis of the first piece remains parallel to the central axis of the second piece. The pieces are lockable in place with respect to each other at the selected offset alignment and rotational orientation.

       5 . The prosthetic device of  claim 1  wherein said positioner has an inside surface defining a hollow portion of said positioner.  
   
   
       6 . The prosthetic device of  claim 1  wherein said sidewall has a generally round interior dimension.  
   
   
       7 . The prosthetic device of  claim 6  wherein said sidewall has six holes therethrough for receiving screws to lock said positioner within said opening.  
   
   
       8 . The prosthetic device of  claim 1  wherein said flange of said first piece is generally parallel to said flange of said second piece.  
   
   
       9 . A prosthetic device comprising: 
 a first piece having a central axis and comprising: 
 a flange with a first side and a second side and defining a plane;  
 a positioner integral with said first side of said flange, said positioner having a positioner geometry with one of more than four faces and round and having a positioner size; and  
 a connector on said second side of said body for connecting said first piece to a first prosthetic component, and  
   a second piece connectable to a second prosthetic component, said second piece having a central axis and comprising: 
 a flange lying in a plane; and  
 a sidewall upstanding from said flange, said sidewall defining an opening for receiving said positioner, said opening having an opening size larger than said positioner size,  
   wherein said flange of said first piece contacts said sidewall of said second piece when said positioner is received within said opening, and    wherein with respect to said second piece, said first piece is selectively and adjustable in all directions within said opening and rotatably adjustable at increments less than 90 degrees, and said plane of said flange of said first piece remains generally parallel to and equally offset from said flange of said second piece during said adjustments.    
   
   
       10 . The prosthetic device of  claim 9  wherein said outside surface of said positioner is comprised of more than four faces.  
   
   
       11 . The prosthetic device of  claim 10  wherein said outside surface of said positioner is comprised of thirty-two faces.  
   
   
       12 . The prosthetic device of  claim 9  wherein said outside surface of said positioner is comprised of a round face.  
   
   
       13 . The prosthetic device of  claim 9  wherein said positioner has an inside surface defining a hollow portion of said positioner.  
   
   
       14 . The prosthetic device of  claim 9  wherein said sidewall has a generally round interior dimension.  
   
   
       15 . The prosthetic device of  claim 14  wherein said sidewall has six holes therethrough for receiving screws to lock said positioner within said opening.  
   
   
       16 . The prosthetic device of  claim 9  wherein said flange of said first piece is generally parallel to said flange of said second piece.  
   
   
       17 . A prosthetic device comprising: 
 a first piece having a central axis and comprising: 
 a flange with a first side and a second side and defining a plane;  
 a positioner integral with said first side of said flange, said positioner having an external surface with more than four faces along an external perimeter; and  
 a connector on said second side of said body for connecting said first piece to a first prosthetic component, and  
   a second piece connectable to a second prosthetic component, said second piece having a central axis and comprising: 
 a flange lying in a plane; and  
 a sidewall upstanding from said flange, said sidewall defining an opening for receiving said positioner, said opening having an opening size larger than said external perimeter of said positioner,  
   wherein said flange of said first piece contacts said sidewall of said second piece when said positioner is received within said opening, and    wherein with respect to said second piece, said first piece is selectively and adjustable in all directions within said opening and rotatably adjustable at increments less than 90 degrees, and said plane of said flange of said first piece remains generally parallel to and equally offset from said flange of said second piece during said adjustments.
