Abstract

Technology is described to provide a foot/ankle prosthesis for individuals with transfemoral limb loss. This technology is able to store and release energy and thus individuals or patients who are using the foot/ankle prosthesis are able to expend less energy when walking or running. The device or system can include a prosthetic foot/ankle system with a linear or rotary hydraulic damper such that the hydraulic damper is attached to dynamic energy storing spring elements. The axis of rotation of the system can be near to that of an intact human ankle. The system can utilize spring elements based on the vertical displacement of the center of pressure of an intact normal foot. The system can also provide user adjustable heel height.

Abstract

A device controls movement of a prosthetic joint or an orthotic joint. The device includes a hydraulic damper having a movable piston in a hydraulic housing of the hydraulic damper. The movable piston forms a first chamber and a second chamber in the hydraulic damper. The device has a first fluid channel coupled to the first chamber. The device has a latch in communication with the first fluid channel. The device has a poppet valve configured to set the latch in a locked position when a defined pressure in the first chamber is reached and restrict movement of the movable piston in a first direction. The device has a manual valve configured to be moveable to an open position when the latch is in the locked position, the manual valve in the open position to allow fluid to flow between the first chamber and the second chamber.

Abstract

Technology is described which can provide a quick disconnect and overload protection mechanism for a prosthetic limb that is used with an osseointegrated percutaneous post. The technology can provide a way to easily don and doff a prosthetic limb. This quick disconnect may also provide a resettable torsional overload protection mechanism and/or a fusible link that may act to protect the osseointegrated percutaneous post from both axial and bending over-loads.

Abstract

Technology is described to provide a locking device to control movement of a prosthetic limb. The technology may include a hydraulic damper having a movable damper wall in a hydraulic housing of the hydraulic damper, and the movable damper wall may form a first chamber and second chamber in the hydraulic damper. A first fluid channel may be coupled to the first chamber. In addition, a latch may be in fluid communication with the first fluid channel. A poppet valve can be configured to set the latch in an open position when pressure is reduced in the first chamber and to stop fluid movement when pressure is increased in the first chamber. A second fluid channel between the second chamber and the latch may enable fluid to flow between the second chamber and the latch.

Abstract

Technology is described for easy and safe attachment of a prosthetic limb to a percutaneous post that has been osseointegrated into the remnant limb of an individual with limb loss. A quick-disconnect device for a prosthetic limb can comprise a percutaneous post support assembly comprising a post locking assembly attached to a percutaneous post. A roller support can be coupled to the percutaneous post support assembly and can support torsional breakaway rollers. A release housing assembly can be coupled to the percutaneous post support assembly, and can comprise a limb support housing supporting a limb attachment structure to support a prosthetic limb. The release housing assembly comprises a torsional breakaway spring. The plurality of torsional breakaway rollers are each biased to the torsional breakaway spring to generate a spring force to restrict or limit rotation of the percutaneous post support assembly. Other breakaway springs and rollers are provided for bending release and axial release.

Abstract

A technology for a prosthetic above-knee device is provided. A socket may be used to attach the device to a residual limb, and may have a rigid body coupled to the socket. The device may include a first link with a first link end coupled through the rigid body to the socket and a second link end coupled to the rigid body. The second link of the device may have a third link end attached to the rigid body, and a fourth link end coupled to a housing. The device may include a hydraulic cylinder with a piston and a hydraulic cylinder link coupled between the rigid body and the piston of the hydraulic cylinder. The stability adjustment nut may adjust a travel distance of the hydraulic cylinder link with respect to the hydraulic cylinder to provide an adjustment of an instant center for stability modification.
