Abstract
An expandable bone device that includes a plurality of linking elements pivotally connected to one another about a hinge, wherein each of the linking elements has upper and lower support plates. An expansion mechanism is operatively connected to the linking elements and can move the upper support plate closer or further with respect to the lower support plate.
Claims9
An expandable bone device comprising:
- a plurality of linking elements pivotally connected to one another about a hinge, each of said linking elements comprising upper and lower support plates;
- an expansion mechanism operatively connected to said linking elements, and which for each of said linking elements, moves said upper support plate closer or further with respect to said lower support plate, and wherein said upper and lower support plates comprise bending structure such that said upper support plate moves non-parallel and/or non-symmetrically with respect to said lower support plate, and
- a force transmission mechanism for transferring an expansion or turning force to said linking elements, wherein said force transmission mechanism comprises torque shafts that pass through said linking elements and which are connected to each other by a universal joint mechanism or by a worm gear mechanism.
