US 12,569,351 B2 · Bone fusion device

Abstract

A bone fusion device for insertion between bones that are to be fused together, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises at least one extendable tab and one or more tab extension assemblies. Each tab extension assembly is able to be adjusted in order to individually control the extension or contraction of a side of the tab thereby enabling adjustment of the height and/or angle of the tab with respect to the body of the bone fusion device. Each tab extension assembly is able to be individually adjusted such that the side controlled by each assembly is raised or lowered until the desired tab angle is achieved. The tab is advantageously positioned and angled to correspond to the vertebrae to help brace the device until the bone has fused.

Dependent claims

A bone fusion device for insertion into a desired location comprising:

a body;
a tab configured to selectively move from a retracted position to an extended position at least partially protruding from the body;
a first extension assembly comprising a first drive mechanism and a first drive screw having a first cutout, the first extension assembly configured to selectively move the tab between the retracted position and the extended position;
and
a second extension assembly comprising a second drive mechanism and a second drive screw, the second extension assembly configured to selectively move the tab between the retracted position and the extended position, wherein a portion of the second drive mechanism is positioned within the first cutout of the first drive screw.

A method of implanting a bone fusion device into a desired location, the method comprising:

inserting the bone fusion device in the desired location, wherein the bone fusion device comprises a body, a tab configured to selectively move from a retracted position to an extended position at least partially protruding from the body, a first extension assembly comprising a first drive mechanism and a first drive screw having a first cutout, the first extension assembly configured to selectively move the tab between the retracted position and the extended position, and a second extension assembly comprising a second drive mechanism and a second drive screw, the second extension assembly configured to selectively move the tab between the retracted position and the extended position, wherein a portion of the second drive mechanism is positioned within the first cutout of the first drive screw;
and
extending the tab from the retracted position to a position at least partially outside the interior cavity by moving at least one of the first drive screw and the second drive screw.

A bone fusion device for insertion into a desired location comprising:

a body;
a tab configured to selectively move from a retracted position to an extended position at least partially protruding from the body;
a first extension assembly configured to move the tab between the retracted position and the extended position, the first extension assembly comprising a first drive screw to control extension of the first extension assembly, wherein the first drive screw is positioned in a horizontal plane and when the first drive screw is turned causes the first extension assembly to move in a vertical direction, perpendicular to the first drive screw;
and
a second extension assembly configured to move the tab between the retracted position and the extended position, the second extension assembly comprising a second drive screw to control extension of the second extension assembly, wherein the second drive screw is non-coaxial to the first drive screw and further wherein the second drive screw is positioned in the horizontal plane and when the second drive screw is turned causes the second extension assembly to move in the vertical direction, perpendicular to the second drive screw.
