Abstract

Systems for manufacturing arthroplasty jigs are disclosed. The systems include positioning components for positioning an arthroplasty jig blank in a machining device (e.g., a computer numerical control (CNC) machine). Arthroplasty jig blanks that may be used in the systems can include an arm fixture component configured to be coupled to the positioning component. Coupling the arm fixture component to the positioning component positions the jig blank body for machining by the machining device. In addition, positioning components, arthroplasty jig blanks, and methods for making arthroplasty jig blanks are disclosed.

Claims

1. An arthroplasty jig manufacturing system comprising:

a first positioning component that is integral with, or configured to be coupled to, a machining device; and

an arthroplasty jig blank comprising a jig blank body including at least one feature specific to a target anatomy site and an arm fixture component, wherein the arm fixture component comprises a first U-shaped member extending from the jig blank body,

wherein the arm fixture component is configured to couple to the first positioning component, and wherein coupling the arm fixture component to the first positioning component positions the jig blank body for machining by the machining device.

2. The arthroplasty jig manufacturing system of claim 1, wherein the first positioning component is configured to position the jig blank body along a plane defined by first and second translational axes of the machining device, when the arm fixture component is coupled to the first positioning component.

3. The arthroplasty jig manufacturing system of claim 2, wherein the arm fixture component comprises a first surface and a second surface, and when the arm fixture component is coupled to the first positioning component, the first surface is aligned with one of the first and second translational axes, and the second surface is aligned with the other of the first and second translational axes.

4. The arthroplasty jig manufacturing, system of claim 1, wherein the first positioning component is configured to rotate the jig blank body around a first rotational axis of the machining device, when the arm fixture component is coupled to the first positioning component.

5. The arthroplasty jig manufacturing system of claim 1, further comprising a second positioning component, wherein the arm fixture component is configured to couple to the second positioning component.

6. The arthroplasty jig manufacturing system of claim 1, further comprising a second positioning component, wherein the arm fixture component comprises a second U-shaped member configured to couple to the second positioning component.

7. The arthroplasty jig manufacturing system of claim 1, further comprising a clamp configured to releasably secure the arm fixture component to the first positioning component.

8. The arthroplasty jig manufacturing system of claim 1, wherein when the arm fixture component is coupled to the first positioning component, the first positioning component positions the jig blank body so that a volume of the jig blank body is accessible by one or more machining tools of the machining device.

9. The arthroplasty jig manufacturing system of claim 8, wherein the first positioning component is configured to position the jig blank body so that at least about 30 cubic inches of the jig blank body is accessible by the one or more machining tools of the machining device.

10. The arthroplasty jig manufacturing system of claim 1, wherein the arm fixture component has a dimension of about 4 inches to about 8 inches.

11. The arthroplasty jig manufacturing system of claim 1, wherein the arthroplasty jig blank comprises a knee arthroplasty jig blank.

12. The arthroplasty jig manufacturing system of claim 1 wherein the arthroplasty jig blank comprises a hip arthroplasty jig blank.

13. The arthroplasty jig manufacturing system of claim 1 wherein the arthroplasty jig blank comprises a shoulder arthroplasty jig blank, an elbow arthroplasty jig blank, or a spinal arthroplasty jig blank.

14. A positioning component for positioning a jig blank body of an arthroplasty jig blank in a machining device, the positioning component comprising:

a positioning component body that is integral with, or configured to be coupled to, the machining device, the positioning component body comprising a first registration portion that is configured to couple with an arm fixture component, wherein the arm fixture component comprises a first U-shaped member extending from the jig blank body,

wherein coupling the first registration portion of the positioning component body with the arthroplasty jig blank positions the jig blank body along or about one or more axes of the machining device to allow for machining of at least a portion of a jig blank body and wherein the jig blank body includes at least one feature specific to a target anatomy site.

15. The positioning component of claim 14, wherein the first registration portion is configured to be aligned with a first translational axis of the machining device, and to slidably engage an arm fixture component of the arthroplasty jig blank.

16. The positioning component of claim 14, wherein the positioning component body comprises a second registration portion configured to be aligned with a second translational axis of the machining device, and to abut the arm fixture component when the first registration portion slidably engages the arm fixture component.

17. The positioning component of claim 14, wherein the positioning component body is configured to rotate about a first rotational axis of the machining device.

18. An arthroplasty jig blank comprising:

a jig blank body; and

an arm fixture component integral with the jig blank body, the arm fixture component comprising a U-shaped member extending from the jig blank body,

wherein the arm fixture component is configured to be coupled to a machining device to position the jig blank body so that at least a portion of the jig blank body can be machined by the machining device and wherein the jig blank body includes at least one feature specific to a target anatomy site.

19. The arthroplasty jig blank of claim 18, wherein the jig blank body can be rotated about or translated along one or more axes of the machining device to allow machining of at least a portion of the jig blank body.

20. The arthroplasty jig blank of claim 18, wherein the arm fixture component is configured to be slidably coupled to a positioning component that is coupled to, or integral with, the machining device.

21. An arthroplasty jig manufacturing system comprising:

first and second positioning components that are integral with, or configured to be coupled to, a computer numerical control machining device; and

an arthroplasty jig blank comprising a jig blank body including at least one feature specific to a target anatomy site and an arm fixture component comprising at least one U-shaped member extending from the jig blank body,

wherein the arm fixture component is configured to couple to the first positioning component and to the second positioning component, and wherein coupling the arm fixture component to the first and second positioning components positions the jig blank body for machining by the machining device.
