摘要:
A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. In one embodiment, a prosthetic foot connection component is connected to a prosthetic lower leg connection component only by means of an elastomeric material, thereby allowing for multi-axis movement of the ankle without requiring direct contact between the two components. In other embodiments of the ankle, a prosthetic foot connection component may be mechanically connected to a prosthetic lower leg connection component. However, the design of the mechanical connection and the use of an elastomeric material casing allows for movement of the ankle without surface-to-surface sliding contact between the two components. Compression of the elastomeric material, as well as one or more mechanical stops may be used to control and limit movement of the ankle.
摘要:
A lower limb prosthesis as a prosthetic foot and an elongate rod formed substantially of unidirectional long fibers embedded in a thermoplastic matrix, the fibers extending substantially parallel to the length of the rod. An adjustment apparatus for the prosthesis includes a pair of pods which may be clamped to the rod and rotated at controlled angles once the thermoplastic rod has been heated to its deformation temperature.
摘要:
A low profile prosthetic foot designed for use with a prosthetic ankle. The prosthetic foot includes at least one toe spring and at least one heel spring. The prosthetic foot is able to absorb shocks generated during ambulation of a user of said foot. When a prosthetic ankle is attached to the prosthetic foot, the position (height) of the ankle preferably approximates the position (height) of a typical human ankle.

摘要:
A system and method for manufacturing a custom prosthetic liner. The system may include a shape capture device for capturing the shape of a residual limb. The captured shape may be used to generate a 3-dimensional electronic liner model using a processor and specialized software. A 3-dimensional electronic model of the residual limb may also be produced. Preferably, an interface is provided that allows a user of the system to alter the shape and/or size of the 3-dimensional model(s) to allow the subsequently-produced liner to accommodate particular features of the residual limb. Data associated with at least the resulting 3-dimensional liner model is provided to a manufacturing facility equipped to produce a custom liner therefrom. The data may be remotely transmitted to the manufacturing facility. A positive likeness of the residual limb is created from the data associated with the 3-dimensional model(s), and is subsequently used as a mold core in the liner molding process.

摘要:
A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. A substantially hollow prosthetic foot connection component includes a receiving cavity for receiving a portion of a lower leg connection component. A retainer or retainer assembly is preferably installed into the receiving cavity to help retain the lower leg connection component therein. Once the necessary components are in place, the remainder of the receiving cavity is substantially filled with an elastomeric material. An external bearing may reside atop the elastomeric material and act in conjunction with the elastomeric material to control ankle flexion.
