SYSTEM FOR LONGITUDINAL CLOSURE OF DISSECTED STERNUMS

摘要

Systems, devices, and methods for longitudinal closure of a dissected sternum are provided. The system includes first and second reinforcing members, fasteners, and closure members. Each reinforcing member is configured to be placed on an outer surface of a respective sternum portion, such that each reinforcing member is longitudinally disposed on an opposite side of a sternum opening with respect to the other reinforcing member. Fasteners may be placed in holes defined in the reinforcing members to secure a respective reinforcing member to a corresponding sternum portion. The closure members, which may be sternal closing wires, may then be wrapped around the sternum portions and the reinforcing members transversely to close the sternum opening. Because the reinforcing members include extended regions having lateral edges that extend away from a midline of the respective reinforcing member, the closure members are moved away from the edges of the bone.

主权项

1. A system for longitudinal closure of a dissected sternum, wherein the dissected sternum comprises first and second sternum portions separated by a sternum opening, the system comprising:
first and second reinforcing members, each reinforcing member configured to be placed on an outer surface of a respective sternum portion such that each reinforcing member is longitudinally disposed on an opposite side of the sternum opening with respect to the other reinforcing member, wherein each reinforcing member defines a plurality of holes, wherein each reinforcing member comprises at least one extended region and at least one connecting portion, wherein the extended region includes a lateral edge extending away from a midline of the respective reinforcing member; a plurality of fasteners, wherein each hole of the first and second reinforcing members is configured to receive one of the fasteners so as to secure a respective reinforcing member to a corresponding sternum portion; and a plurality of closure members, each closure member configured to extend between adjacent ribs from a first lateral edge of the first sternum portion to a second lateral edge of the second sternum portion so as to span the sternum opening, wherein each extended region is configured to receive at least one of the closure members, wherein the plurality of closure members is configured to hold together the first and second sternum portions such that the sternum opening is in a substantially closed position, wherein the lateral edge of the extended region is beveled, and wherein a medial edge of each reinforcing member is straight.
