Abstract

Various examples are provided for modular prosthetic devices and their use. In one example, a device includes a chassis assembly including a joint portion; and an interchangeable module that can be removably attached to the chassis assembly. The interchangeable modules can be configured for use in a wide variety of applications. The interchangeable modules can be quickly exchanged for different activities.

First claim

We claim at least the following:

1. An interchangeable prosthetic module for removable attachment to a prosthetic device, comprising:
a first end configured to engage with a mounting base of a chassis assembly of the prosthetic device; and
a second end opposite the first end, the second end configured to engage with a joint portion of the chassis assembly, the second end comprising a locking mechanism including a pair of flanges configured to engage with a cavity of the joint portion, where the pair of flanges rest in a disengaged position to facilitate insertion in the cavity and flex outward to engage with the cavity to secure the locking mechanism to the joint portion, wherein the pair of flanges is engaged with the cavity via rotation of a lever.

2. The interchangeable prosthetic module of claim 1 , wherein the pair of flanges tilt inward towards each other in the disengaged position to facilitate insertion in the cavity and flex outward to engage with a surface of the cavity.

3. The interchangeable prosthetic module of claim 1 , wherein the pair of flanges is engaged with the cavity via the lever and a locking wedge.

4. The interchangeable prosthetic module of claim 3 , wherein the lever forces the locking wedge between the pair of flanges when rotated from an extend position to a locked position.

5. The interchangeable prosthetic module of claim 1 , wherein the joint portion comprises the lever.

6. The interchangeable prosthetic module of claim 1 , wherein the joint portion comprises a rotatable mounting plate including the cavity.

7. The interchangeable prosthetic module of claim 6 , wherein the locking mechanism engages the cavity to secure the rotatable mounting plate in a load bearing position.

8. An interchangeable prosthetic module for removable attachment to a prosthetic device, comprising:
a first end configured to engage with a mounting base of a chassis assembly of the prosthetic device; and
a second end opposite the first end, the second end configured to engage with a joint portion of the chassis assembly, the second end comprising a locking mechanism including a pair of flanges configured to engage with a cavity of the joint portion, where the pair of flanges rest in a disengaged position to facilitate insertion in the cavity and flex outward to engage with the cavity to secure the locking mechanism to the joint portion, wherein the interchangeable prosthetic module is secured to the chassis assembly via at least one mating slot and complementary tab.

9. The interchangeable prosthetic module of claim 8 , wherein the at least one mating slot comprises a groove configured to secure the interchangeable prosthetic module in the chassis assembly via the complementary tab.

10. The interchangeable prosthetic module of claim 9 , wherein the second end of the chassis assembly and the mounting base of the chassis assembly comprise the groove and the complementary tab.

11. The interchangeable prosthetic module of claim 10 , wherein the second end of the interchangeable prosthetic module comprises the groove and the mounting base comprises the complementary tab.

12. The interchangeable prosthetic module of claim 10 , wherein the mounting base comprises the groove and the second end of the interchangeable prosthetic module comprises the complementary tab.

13. The interchangeable prosthetic module of claim 9 , wherein the interchangeable prosthetic module and a structural frame of the chassis assembly comprise mounting ridges and mounting grooves configured to secure the interchangeable prosthetic module in the structural frame.

14. The interchangeable prosthetic module of claim 13 , wherein the structural frame comprises the mounting base.

15. An interchangeable prosthetic module for removable attachment to a prosthetic device, comprising:
a first end configured to engage with a mounting base of a chassis assembly of the prosthetic device; and
a second end opposite the first end, the second end configured to engage with a joint portion of the chassis assembly, the second end comprising a locking mechanism including a pair of flanges configured to engage with a cavity of the joint portion, where the pair of flanges rest in a disengaged position to facilitate insertion in the cavity and flex outward to engage with the cavity to secure the locking mechanism to the joint portion, wherein a prosthetic attachment is attached to the chassis assembly via a mounting portion.

16. The interchangeable prosthetic module of claim 15 , comprising a damper driven mechanism.

17. The interchangeable prosthetic module of claim 16 , wherein the pair of flanges is coupled to the damper driven mechanism.

18. The interchangeable prosthetic module of claim 17 , wherein the damper driven mechanism comprises a piston assembly coupled to the pair of flanges.

19. The interchangeable prosthetic module of claim 15 , wherein the joint portion is configured to be secured to an osseous implant or prosthetic socket.
