  • Patent number: 7112227
    Abstract: 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.

  • Publication number: 20060062449
    Abstract: An apparatus is described that uses cameras arranged on, in, or about a structure adapted to fit over, around, or about an object to be measured. Projectors are arranged on, in, or about the structure to project light toward the object. The projectors and/or the cameras may be electronically connected to a computer processor which controls their operation. A light pattern is projected onto the object to be measured while the cameras capture images of the object from several angles about the object. The data collected from the images taken of the pattern on the object may be used to form a mathematical three-dimensional data model of the object. The three-dimensional model may be displayed in digital form on a visual display device of a personal computer. The three-dimensional model of the object may be used in the manufacture of fitments or coverings for the object. In one example, the apparatus is used by a prosthetist to map the stump of an amputee to properly fit the amputee with a prosthetic device.

  • Patent number: 6979355
    Abstract: A prosthetic limb comprises a socket for receiving a patient's residual limb, and an upright assembly. The socket includes a base provided in its distal end. The base includes a chamber therewithin and an channel for providing fluid communication between the chamber and the interior of the socket. A duct extends through the socket and engages the base such that it is in fluid communication with the chamber. A valve is coupled to the duct to allow controlled or forced gas transfer to and from the interior of the socket. A seal is provided between the base and the socket to facilitate suction between the patient's residual limb and the socket.

  • Patent number: 6863695
    Abstract: A prosthetic foot includes an adapter element securable to a residual limb, a foot plate having a heel portion and a toe portion along the length thereof, at least one toe spring connected between the adapter element and the toe portion of the foot plate, and a heel spring connected between the adapter element and the heel portion. The heel spring may be a leaf spring or a tube type shock absorber. The concave side of the leaf spring exhibits a plurality of transverse ribs. Alternatively, a tubular pylon may have a collar mounted thereon for movement along the length of the pylon. A toe spring and a heel spring extend from the collar to form toe and heel portions of the prosthetic foot. A further heel spring is connected between the heel portion and another end of the pylon, and a non-extensible band extends between the heel portion and the collar. As another alternative, a tubular pylon has one end securable to a residual limb, and a collar is mounted to the pylon for movement along the length of the pylon.

  • Publication number: 20050038525
    Abstract: 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.

  • Patent number: 6699295
    Abstract: A multi-axis prosthetic ankle includes a bottom component connected to a prosthetic foot, a lower leg connection component connected to a prosthetic lower leg, an elastomeric material securely connecting the bottom component with the lower leg connection component, and a mechanical device suspended in the elastomeric material. The mechanical device is formed of a first bracket connected to the bottom component and a second bracket connected to the lower leg connection component. The first and second brackets interlockingly float in the elastomeric material, and are not in direct contact with one another, thereby permitting relative movement of the bottom component and the lower leg connection component by deformation of the elastomeric material. At least one mechanical stop is positioned to prevent the relative angular movement of the ankle from deforming the elastomeric material beyond the elastic limit thereof.

  • Patent number: 6613097
    Abstract: A hydraulic swing phase control unit for an artificial lower limb including a thigh part and a shin part connected at a knee joint, includes a hydraulic cylinder connected to one of the thigh part and the shin part, a piston movable in the hydraulic cylinder and connected to the other of the thigh part and the shin part, a fluid passage positioned to pass hydraulic fluid pressurized by movement of the piston in the hydraulic cylinder; and a variable sharp edged orifice at the fluid passage. The variable orifice is formed from a sharp edged orifice and a manually rotatable sleeve positioned to at least partly overlap the orifice. At least one low restriction fluid passage in the cylinder is fluidically connected in parallel with the variable sharp edged orifice to permit minimal resistance to movement of the piston during a portion of the movement thereof.

  • Patent number: 6605118
    Abstract: A prosthetic attachment locking assembly includes a distal adaptor fittable in the bottom of a socket for a residual limb stump and has an upper surface configured to accept an end of a stump liner. The internal surface of the socket merges smoothly with the upper surface of the distal adaptor. The distal adaptor has a pin bore through which a lock pin of the stump liner may extend, and a lower surface having a plurality of projections. A lock body of a prosthetic attachment lock has a pinion gear engagable with the lock pin to lock the lock pin, and an upper surface matably engagable with the projections such that the lock body and the distal adaptor may be connected via the projections and the upper surface of the lock body. The pinion gear is mounted to a centering axle. A one-way clutch for the pinion gear incorporates a sleeve non-rotatably mounting the centering axle such that the centering axle does not bind when it is pressed to move longitudinally.
