US Classification:

623 49, 623 55

Abstract:

Compositions are provided for a prosthetic ankle comprising: a joint housing having a bottom surface, a clevis coupled to the joint housing such that the clevis can rotate about the joint housing, a prosthetic coupling structure that couples the clevis to an amputee, and an articulating joint contained in the joint housing. Additionally, a portion of the bottom surface of the joint housing can be curved allowing a substrate a preset amount of flexion when coupled thereto and flexed in a concave position.

International Classification:

A61F 2/58
A61F 2/68

Abstract:

A prosthetic hand system may include a plurality of prosthetic fingers and a prosthetic thumb. The prosthetic hand system may include a thumb drive mechanism that may be used to actuate the prosthetic thumb. In some examples, the thumb drive mechanism may be configured to enable the prosthetic thumb to perform a pinching or grasping motion and a release motion. The prosthetic hand system may also include a backlock that enables the prosthetic thumb to maintain pinching or gripping pressure after a motor has been disengaged. The prosthetic hand system may also include a gear lock that may be configured to lock a finger joint. The prosthetic hand system may also include an adaptive gripping joint that may be located on each prosthetic finger. In some examples, the adaptive gripping joint may be configured to passively adapt the plurality of prosthetic fingers to one or more differently shaped objects.
