Abstract

Technology is described to provide a foot and ankle prosthesis for individuals with lower limb loss. This technology is able to store and release energy and individuals or patients who are using the foot/ankle prosthesis may be able to expend less energy when walking. The system includes a hydraulic damper attached to dynamic energy storing spring elements. The axis of rotation of the system can be near to that of an intact human ankle, providing biomimetic function. The system can utilize spring elements based on the vertical displacement of the center of pressure of an intact normal foot. A hydraulic system can provide user adjustable heel height and adaptation to inclines. The dorsiflexion and plantar flexion resistances can be independently adjusted manually or electrically. In addition, the system can be automatically locked in dorsiflexion when loaded and unlock when unloaded.

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.

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.

Abstract

A multi-axis wrist device is provided for use with a prosthetic limb. The wrist device includes a base plate that is configured for attachment to a prosthetic limb. A cross piece, having first and second axes, can be coupled to the base plate. A prosthetic attachment can be coupled to the cross piece. The cross piece can enable a user to simultaneously flex the prosthetic attachment in two different axes. A first and second torsional spring can be coupled to the first and second axes, respectively, to enable the prosthetic attachment to be biased toward a center point.

Abstract

A device and system is provided for a prosthetic device having an articulating joint for a leg amputee. The device includes a joint housing forming a chamber, and the chamber has a first opening. A rotary hub can be disposed within the joint housing and configured to act as the articulating joint. One or more vanes can extend outwardly from the rotary hub, and the vane is configured to actuate fluid flow through the first opening.
