Abstract

An embodiment of a bone plate comprises a main body which is fixed to a side of the fracture and having a hole in which a connecting element is inserted for purposes of this fixation procedure; a movable part which is associated with the main body, is fixed to the other side of the fracture and having a hole in which a connecting element is inserted for purposes of this fixation procedure and being moveable with respect to the main body; a displacement mechanism enabling movement of the movable part relative to the main body, on the center of which it is positioned; a locking element which stops operation of the displacement mechanism, thereby restricting the movement of the movable part; and a displacement element which is associated with the displacement mechanism for controlling thereof externally.

First claim

We claim:

1. A bone plate adapted to use in surgical bone operations, which is directly fixed to a bone and allows external manipulation, and comprising; a main body fixed to one side of a fracture and having a hole in which a connecting element is configured to be inserted for purposes of this fixation procedure, wherein the main body comprises at least two pairs of contact surfaces in the form of two mutual extensions, which are positioned on a bone contacting side of the main body and form a conduit structure inside the main body; a movable part which is associated with the main body and allowed to slide inside the conduit structure formed inside the main body without contacting the bone, the movable part being fixed to another side of the fracture and having an other hole in which a connecting element is configured to be inserted for purposes of this fixation procedure; and a displacement mechanism enabling the movable part to slide inside the main body, wherein the displacement mechanism is positioned along a center of the main body and wherein the bone plate comprises: a locking element which restricts sliding of the movable part inside the main body by stopping operation of the displacement mechanism, and a displacement element associated with the displacement mechanism to provide external control thereof; wherein the main body comprises a seat positioned along the center thereof, and in which the displacement element is inserted.

2. The bone plate according to claim 1 , wherein the movable part is positioned on the side of said main body that faces the bone.

3. The bone plate according to claim 1 , wherein the main body includes a plate structure.

4. The bone plate according to claim 1 , wherein the movable part includes a plate structure.

5. The bone plate according to claim 1 , wherein said displacement mechanism comprises a gear positioned on the side of the main body that faces the bone, the gear being associated with the displacement element and, by means of the displacement element, being movable rotationally, and a displacement part which is positioned on a side of the movable part that faces the main body, and translates rotational movement of the gear into linear movement, thus enabling the movable part to move relative to the main body.

6. The bone plate according to claim 5 , wherein said displacement part is a component that is attached to the movable part externally.

7. The bone plate according to claim 6 , wherein the displacement part is a rack.

8. The bone plate according to claim 5 , wherein the displacement part is integral with the movable part by making at least one of the side that faces the main body or an other side of the movable part, during manufacturing thereof, in such a structure which translates the rotational movement of the gear into the linear movement.

9. The bone plate according to claim 5 , wherein the locking element is located on the side of the main body that faces the bone such that the locking element restricts the movement of the movable part by preventing uncontrolled movement of the gear.

10. The bone plate according to claim 1 , wherein the main body comprises a conduit positioned on an other side thereof, and in correspondence with the hole on the movable part.

11. The bone plate according to claim 1 , wherein the movable part comprises a conduit positioned on an other side thereof, and through which the displacement element is passed and connected to the displacement mechanism.
