Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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.
