Abstract
External fixator assemblies, systems, and methods thereof. An external fixator system may include a plurality of fixator assemblies configured to connect a plurality of pins, for example, positioned on opposite sides of a fractured bone, with one more rods. The fixator assemblies may include a plurality of clamp assemblies which are configured to rotate relative to one another when the fixator assembly is in an unlocked position.
Claims20
An external fixator assembly comprising:
- a first shaft having a first coupling end and a first free end;
- a second shaft having a second coupling end and a second free end;
- a coupling pivotally retaining the first coupling end and the second coupling end;
- a first clamp assembly disposed on the first shaft between the coupling and the first free end, the first clamp assembly comprising:
- a first inner clamp member disposed proximate to the coupling, the first inner clamp member having a first inner slot;
- a first outer clamp member disposed proximate to the first free end, the first outer clamp member having a first outer slot;
- and
- a first biasing member disposed in the first inner slot and the first outer slot such that first biasing member biases the first inner clamp member toward the first outer clamp member;
- and
- a second clamp assembly disposed on the second shaft between the coupling and the second free end, the second clamp assembly comprising:
- a second inner clamp member disposed proximate to the coupling, the second in the clamp member having a second inner slot;
- a second outer clamp disposed proximate to the second free end, the second outer clamp member having a second outer slot;
- and
- a second biasing member disposed in the second inner slot and the second outer slot such that the second biasing member biases the second inner clamp member toward the second outer clamp member.

- a pin configured to engage bone, a portion of the pin being received in the first or second clamp assembly;
- and
- a rod received in the other of the first or second clamp assembly.
