Abstract

A surgical device includes an elongate body extending from a proximal end to a distal end. The distal end of the elongate body defines a notch sized and configured to receive a reamer. A coupling assembly is supported by the elongate body and includes a reamer guide body disposed at the distal end of the elongate body. The reamer guide body configured to move between a first position and a second position in which the reaming guide body extends at least partially across the notch. A locking assembly is supported by the elongate body and is configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

Claims

1. A system, comprising:

a first surgical device having a hollow body that extends from a first side to a second side and includes a third side and a fourth side, the third and fourth sides extending between the first side and the second side and being disposed opposite one another, at least a portion of the hollow body being sized and configured to be received within a resected space between a first bone and a second bone, the first surgical device including an engagement structure extending from the third side and having a conformal engagement surface configured to engage one of the first bone and the second bone; and

a second surgical device configured to be at least partially received within the hollow body of the first surgical device via an opening defined by the first side of the first surgical device, the second surgical device including

an elongate body extending from a first end to a second end, the first end defining a notch sized and configured to receive a third surgical device, and

a coupling assembly supported by the elongate body, the coupling assembly including a reamer guide body configured to move between a first position and a second position in which the reamer guide body extends at least partially across the notch.

2. The system of claim 1, wherein the second surgical device includes a locking assembly supported by the elongate body, the locking assembly configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

3. The system of claim 1, wherein the coupling assembly is sized and configured to be received within the hollow body of the first surgical device.

4. The system of claim 1, wherein the third and fourth sides of the first surgical device each define a respective aperture sized and configured to receive a third surgical device therein.

5. The system of claim 1, wherein the coupling assembly includes first and second rods disposed within a longitudinal channel defined by the elongate body, the first rod coupled to a head extending outwardly from the longitudinal channel, and the second rod pivotally coupled to the first rod and to an end of the reamer guide.

6. The system of claim 5, wherein the coupling assembly includes a biasing member disposed within the longitudinal channel, the biasing member configured to bias the head toward the second end.

7. The system of claim 1, wherein the locking assembly includes

a button slidably positioned within a cavity defined at the proximal end of the elongate body, and

a biasing member configured to urge the button in a direction towards the coupling assembly.

8. The system of claim 1, wherein the elongate body includes a step along at least one side.

9. The system of claim 1, wherein the reamer guide body includes

an arcuate surface configured to support a reamer, the reamer guide body disposed adjacent to a first hole configured to receive a first pin for pivotably coupling the reamer guide body to the distal end of the elongate body, and

a second hole is defined adjacent to the first hole, the second hole configured to receive a second pin for pivotably coupling the reamer guide body to a pivoting rod of the coupling assembly.

10. A system, comprising:

a first surgical device having a hollow body that extends from a first side to a second side and includes a third side and a fourth side, the third and fourth sides extending between the first side and the second side and being disposed opposite one another, at least a portion of the hollow body being sized and configured to be received within a resected space between a first bone and a second bone, the first surgical device including an engagement structure extending from the third side and having a conformal engagement surface configured to engage one of the first bone and the second bone; and

a second surgical device configured to be at least partially received within the hollow body of the first surgical device via an opening defined by the first side of the first surgical device, the second surgical device including

an elongate body extending from a first end to a second end, the first end defining a notch sized and configured to receive a third surgical device,

a coupling assembly supported by the elongate body, the coupling assembly including a reamer guide body configured to move between a first position and a second position in which the reamer guide body extends at least partially across the notch, and

a locking assembly supported by the elongate body, the locking assembly configured to releasably engage the coupling assembly to maintain the reamer guide body in the second position.

11. The system of claim 10, wherein the coupling assembly is sized and configured to be received within the hollow body of the first surgical device.

12. The system of claim 10, wherein at least one of the third and fourth sides of the first surgical device defines an respective aperture sized and configured to receive a third surgical device therein.

13. The system of claim 10, wherein the coupling assembly includes first and second rods disposed within a longitudinal channel defined by the elongate body, the first rod coupled to a head extending outwardly from the longitudinal channel, and the second rod pivotally coupled to the first rod and to an end of the reamer guide.
