Abstract
A distractor frame is disclosed the frame, comprising an upper pin, a lower pin positioned substantially parallel to the upper pin, a pair of adjustment mechanisms, wherein each adjustment mechanism couples to the upper pin and the lower pin such that each adjustment mechanism is positioned generally perpendicular to upper and lower pins, wherein each adjustment mechanism comprises a shaft, a first means coupling the shaft for coupling the upper pin to the shaft, a threaded rod coupled to an end of the shaft, a cylindrical sleeve adapted for threadedly engaging the threaded rod, such that a portion of the shaft and a portion of the threaded rod may be positioned within the cylindrical sleeve, and a second means coupled to the cylindrical sleeve for coupling the lower pin.
Claims13
A surgical distractor frame adapted to distract at least two bone segments, the distractor comprising:
- an elongate shaft having a first end and an opposite second end;
- an elongate sleeve having an internal bore with a distal end adapted to telescopingly receive said second end of said elongate shaft;
- a first bone anchor engaged to a first bone segment and interconnected with said elongated shaft;
- a second bone anchor engaged to a second bone segment and interconnected with said elongate sleeve;
- and
- an expansion mechanism disposed between said elongate shaft and said elongate sleeve, said expansion mechanism engaging said second end to adjust the distance between said first end and said distal end to thereby adjust the distance between the first bone segment and the second bone segment.
A surgical distractor frame adapted to distract at least two bone segments, the distractor comprising:
- an elongate shaft having a first end and an opposite second end;
- an elongate sleeve having an internal bore with a distal end adapted to telescopingly receive said second end of said elongate shaft;
- a first bone anchor engaged to a first bone segment and interconnected with said elongated shaft;
- a second bone anchor engaged to a second bone segment and interconnected with said elongate sleeve, said elongated shaft having a substantially uniform diameter along its length extending between the first bone anchor and the second bone anchor;
- and
- an expansion mechanism disposed between said elongate shaft and said elongate sleeve, said expansion mechanism operable to adjust the distance between said first end and said distal end to thereby adjust the distance between the first bone segment and the second bone segment.
A surgical distractor frame adapted to distract at least two bone segments, the distractor comprising:
- an elongate shaft having a first end and an opposite second end, and a longitudinal axis extending between said first end and said second end;
- an elongate sleeve having an internal bore with a distal end adapted to telescopingly receive said second end of said elongate shaft;
- a first bone anchor engaged to a first bone segment and interconnected with said elongated shaft;
- a second bone anchor engaged to a second bone segment and interconnected with said elongate sleeve;
- and
- an expansion mechanism disposed between said elongate shaft and said elongate sleeve and in substantial axial alignment with said longitudinal axis, said expansion mechanism operable to adjust the distance between said first end and said distal end to thereby adjust the distance between the first bone segment and the second bone segment.
