Abstract

A prosthetic device comprising a first prosthetic digit, a first engagement portion, and a first stopping portion, wherein the first engagement portion is capable of engaging with the first stopping portion to lock the first prosthetic digit in a position of flexion in response to a force applied to the first prosthetic digit.

Claims (70)

1 . A prosthetic device comprising:

a first prosthetic digit;

a first engagement portion; and

a first stopping portion;

wherein the first engagement portion is capable of engaging with the first stopping portion to lock the first prosthetic digit in a position of flexion in response to a force applied to the first prosthetic digit.

2 . A prosthetic device according to claim 1 , further comprising:

a second prosthetic digit.

3 . A prosthetic device according to claim 2 , further comprising:

a second engagement portion; and

a second stopping portion;

wherein the second engagement portion is capable of engaging with the second stopping portion to lock the second prosthetic digit in a position of flexion in response to a force applied to the second prosthetic digit.

4 . A prosthetic device according to claim 3 , wherein

the first prosthetic digit is capable of locking in a position of flexion independently from the second prosthetic digit.

5 . A prosthetic device according to claim 4 , further comprising:

a linkage coupled to the first prosthetic digit and the second prosthetic digit;

wherein the linkage is configured to extend the first prosthetic digit when the first prosthetic digit is not locked in a position of flexion; and

wherein the linkage is configured to extend the second prosthetic digit when the second prosthetic digit is not locked in a position of flexion.

6 . A prosthetic device according to claim 5 , further comprising:

a third prosthetic digit and a fourth prosthetic digit;

wherein the first prosthetic digit, second prosthetic digit, third prosthetic digit, and fourth prosthetic digit comprise prosthetic fingers.

7 . A prosthetic device according to claim 1 , wherein

the first engagement portion comprises at least one notch positioned on the first prosthetic digit; and

the first stopping portion comprises a latch.

8 . A prosthetic device according to claim 7 , wherein

the first stopping portion is positioned adjacent to the first prosthetic digit.

9 . A prosthetic device according to claim 4 , wherein

the first engagement portion comprises at least one notch positioned on the first prosthetic digit;

the first stopping portion comprises a latch positioned adjacent to the first prosthetic digit;

the second engagement portion comprises at least one notch positioned on the second prosthetic digit; and

the second stopping portion comprises a latch positioned adjacent to the second prosthetic digit.

10 . A prosthetic device according to claim 9 , further comprising:

a linkage coupled to the first prosthetic digit and the second prosthetic digit;

wherein the linkage is configured to extend the first prosthetic digit when the first prosthetic digit is not locked in a position of flexion; and

wherein the linkage is configured to extend the second prosthetic digit when the second prosthetic digit is not locked in a position of flexion.

11 . A prosthetic device according to claim 10 , further comprising:

a third prosthetic digit and a fourth prosthetic digit;

wherein the first prosthetic digit, second prosthetic digit, third prosthetic digit, and fourth prosthetic digit comprise prosthetic fingers.

12 . A prosthetic device according to claim 1

wherein the first prosthetic digit comprises a first phalanx and a second phalanx; and

wherein the first engagement portion comprises a first linkage joining the first phalanx and the second phalanx.

13 . A prosthetic device according to claim 12 ,

wherein the first stopping portion is positioned on the first phalanx of the first prosthetic digit.

14 . A prosthetic device according to claim 4 , wherein

the first prosthetic digit comprises a first phalanx and a second phalanx;

the first engagement portion comprises a first linkage joining the first phalanx and the second phalanx;

the second prosthetic digit comprises a third phalanx and a fourth phalanx; and

the second engagement portion comprises second linkage joining the third phalanx and the fourth phalanx.

15 . A prosthetic device according to claim 14 , wherein

wherein the first stopping portion is positioned on the first phalanx of the first prosthetic digit; and

wherein the second stopping portion is positioned on the third phalanx of the second prosthetic digit.

16 . A prosthetic device according to claim 15 , further comprising:

a linkage coupled to the first prosthetic digit and the second prosthetic digit;

wherein the linkage is configured to extend the first prosthetic digit when the first prosthetic digit is not locked in a position of flexion; and

wherein the linkage is configured to extend the second prosthetic digit when the second prosthetic digit is not locked in a position of flexion.

17 . A prosthetic device according to claim 16 , further comprising:

a third prosthetic digit and a fourth prosthetic digit;

wherein the first prosthetic digit, second prosthetic digit, third prosthetic digit, and fourth prosthetic digit comprise prosthetic fingers.

18 . A prosthetic device according to claim 4 , wherein

the first engagement portion comprises at least one notch positioned on the first prosthetic digit;

the first stopping portion comprises a latch positioned adjacent to the first prosthetic digit;

the second prosthetic digit comprises a first phalanx and a second phalanx;

the second engagement portion comprises a first linkage joining the first phalanx and the second phalanx; and

the second stopping portion is positioned on the first phalanx of the second prosthetic digit.

19 . A prosthetic device according to claim 18 , further comprising:

a linkage coupled to the first prosthetic digit and the second prosthetic digit;

wherein the linkage is configured to extend the first prosthetic digit when the first prosthetic digit is not locked in a position of flexion; and

wherein the linkage is configured to extend the second prosthetic digit when the second prosthetic digit is not locked in a position of flexion.

20 . A prosthetic device according to claim 19 , further comprising:

a third prosthetic digit and a fourth prosthetic digit; and

wherein the first prosthetic digit, second prosthetic digit, third prosthetic digit, and fourth prosthetic digit comprise prosthetic fingers.
