US 10,376,289 B2 · Cross connector system

Abstract

The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A cross connector system for use during a spinal fixation procedure is provided. The system includes at least one bridge defining a coupling bore and having a pair of downwardly extending arms for coupling to a first bone engaging member. The system includes a contoured bar having a first end offset from a second end, and a bore having a central axis. The system includes an expansion ring received within the bore, and a locking device received through the expansion ring and the coupling bore. The locking device is operable in a first state in which the contoured bar is movable about the central axis of the bore and in a second state in which the contoured bar fixed relative to the central axis of the bore.

Dependent claims

A cross-connector system for use during a spinal fixation procedure comprising:

at least one coupling device defining a coupling bore and having a pair of downwardly extending arms adapted to be coupled to a rod or a bone engaging member;
a contoured bar having a first end offset from a second end, the first end defining a bore having a central axis and the second end defining a slot;
an expansion ring received within the bore of the contoured bar, the expansion ring including a slot configured to expand the expansion ring in a circumferential direction;
a locking device received through the expansion ring and the coupling bore for coupling the at least one coupling device to the contoured bar, the locking device operable in a first state in which the contoured bar is movable about the central axis of the bore and in a second state in which the contoured bar is fixed relative to the central axis of the bore so as to fixedly couple the contoured bar to the at least one coupling device;
and
a planar bar having a first end and a second end, the first end of the planar bar coupled to the slot to enable relative movement between the contoured bar and the planar bar.

a second coupling device defining a second coupling bore and having a second pair of downwardly extending arms adapted to be coupled to a second rod;
a linkage system having a first end defining a first bore and a second end defining a second bore;
a first expansion ring received within the first bore of the linkage system;
a second expansion ring received within the second bore of the linkage system;
a first locking device received through the first expansion ring and the first coupling bore of the first coupling device to couple the first coupling device to the first end of the linkage;
and
a second locking device received through the second expansion ring and the second coupling bore of the second coupling device to couple the second coupling device to the second end of the linkage;
wherein the first and second coupling devices are each pivotable relative to the linkage system.
