Abstract
An expandable prosthetic device used as a prosthesis during surgery. The expandable prosthetic device is configured for use in the extremities of a body such as, but not limited to, use in the expansion of the lateral or medial column of a foot. The expandable prosthetic device includes a drive block, a linkage block, a drive screw, a first endplate, a second endplate, and first and sets of linkages. Rotation of the drive screw causes movement of the linkage block relative to the drive block and/or movement of the first endplate relative to the second endplate.
Claims32
An expandable prosthetic device;
- said expandable prosthetic device comprises:
- a drive block;
- said drive block includes a drive block opening and a slot region;
- a linkage block;
- said linkage block includes a linkage housing and a linkage bar;
- said linkage bar is at least partially positioned in said linkage housing;
- said linkage block is movable within said slot region of said drive block;
- a drive screw;
- said drive screw includes a head and body portion;
- said head is rotatably positioned in within said drive block opening;
- said body portion is threadingly connected to said linkage block;
- first and second endplates;
- said first endplate includes a front portion and a rear portion;
- said second endplate includes a front portion and a rear portion;
- said rear portion of said first and second endplates are pivotally connected together;
- and,
- first and second sets of linkages;
- said first set of linkage includes first and second linkages;
- said second set of linkage includes first and second linkages;
- said first linkage of said first set of linkages engages said linkage bar and said first endplate;
- said first linkage of said second set of linkages engages said linkage bar and said first endplate;
- said second linkage of said first set of linkages engages said linkage bar and said second endplate;
- said second linkage of said second set of linkages engages said linkage bar and said second endplate;
- said first and second sets of linkages are spaced from one another;
- and
- wherein rotation of said drive screw simultaneously causes I) movement of said linkage block relative to said drive block, and II) movement of said first endplate relative to said second endplate.
