Abstract

A sternal closure clamp for securing and retaining longitudinally divided halves of a sternum, the clamp having a pair of body members each having a pair of engagement members, a pair of guide beam members affixed to a first of the body members and extending through a second of the body members, the guide beam members having an I-beam cross-sectional configuration, and a threaded rod member retained by the first body member and passing through the second body member, whereby rotation of the rod member in a first direction increases the distance between the body members and rotation in a second direction decreases the distance between the body members.

Claims

1. A sternal closure clamp comprising:

a first body member and a second body member, each said body member having a pair of engagement members connected thereto, said engagement members each comprising a leg member and foot member;

an internally threaded bore disposed in said second body member;

a pair of parallel guide beam members affixed to said first body member and extending through said second body member, said guide beam members having an I-beam cross-sectional configuration; and

a threaded rod member retained by said first body member in a rotatable manner and passing through said threaded bore of said second body member, whereby rotation of said rod member in a first direction increases the distance between said body members and rotation in a second direction decreases the distance between said body members.

2. The clamp of claim 1, further comprising means for locking said first and second body members in a fixed relative position.

3. The clamp of claim 2, wherein said means for locking said first and second body members in a fixed relative position comprises a set screw positioned in said first body member, such that said set screw abuts said rod member.

4. The clamp of claim 1, wherein said foot members of said first body member and said foot members of said second body member are configured and aligned such that the foot members do not abut when said first and second body members are brought closely together.

5. The clamp of claim 2, wherein said foot members of said first body member and said foot members of said second body member are configured and aligned such that the foot members do not abut when said first and second body members are brought closely together.

6. The clamp of claim 3, wherein said foot members of said first body member and said foot members of said second body member are configured and aligned such that the foot members do not abut when said first and second body members are brought closely together.

7. A sternal closure clamp comprising:

a first body member and a second body member, each said body member having a pair of engagement members connected thereto, said engagement members each comprising a leg member and foot member, wherein said foot members of said first body member are directed toward said foot members of said second body member and said foot members of said second body member are directed toward said foot members of said first body member;

an internally threaded bore disposed in said second body member;

a pair of parallel guide beam members affixed to said first body member and extending through said second body member, said guide beam members having an I-beam cross-sectional configuration; and

a threaded rod member retained by said first body member in a freely rotatable manner and passing through said threaded bore of said second body member, said rod member being parallel to said guide members, said threaded bore of said second body member and said threaded rod cooperating in a mated manner whereby rotation of said rod member causes axial movement of said second body member relative to said first body member and said guide beam members.

8. The clamp of claim 7, further comprising means for locking said first and second body members in a fixed relative position.

9. The clamp of claim 8, wherein said means for locking said first and second body members in a fixed relative position comprises a set screw positioned in said first body member, such that said set screw abuts said rod member.

10. The clamp of claim 7, wherein said foot members of said first body member and said foot members of said second body member are configured and aligned such that the foot members do not abut when said first and second body members are brought closely together.

11. The clamp of claim 8, wherein said foot members of said first body member and said foot members of said second body member are configured and aligned such that the foot members do not abut when said first and second body members are brought closely together.

12. The clamp of claim 9, wherein said foot members of said first body member and said foot members of said second body member are configured and aligned such that the foot members do not abut when said first and second body members are brought closely together.
