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： An adapter assembly which is particularly advantageous in allowing for adjusting and positioning of prosthetic devices which are attached to a stump or stump socket. The adapter is particularly advantageous for orienting and positioning of a Symes prosthesis, due to the small space requirements. In accordance with a preferred embodiment, an interface member is attached to a stump socket, with a nut movably disposed inside of a cavity of the interface member. The nut includes an aperture extending therethrough, and receives a hollow laminating bolt which clamps the prosthesis and adapter assembly in place to allow the user to test the prosthesis. If adjustments are needed, the hollow bolt can be loosened, and adjustments performed via the movably disposed nut. Once a desired position is achieved, a resin is injected through the laminating bolt and into the cavity of the interface. After the resin has hardened or cured, the hollow laminating bolt is replaced with a solid bolt.

摘要： An adjustable lower limb prosthesis has a pylon connected to both a prosthetic foot and to the stump adapter by way of a foot/pylon joint and a pylon/stump joint, respectively. Each of the joints is similar and includes a tapered socket holding a truncated conical wedge sleeve. The wedge sleeve has a bore which may be angled with respect to the cone axis, and into which the pylon is fitted. A cap locks the wedge sleeve in the bore and locks the pylon in the wedge sleeve. For adjusting the prosthesis, a set of wedge sleeves are available to the prosthetist, each having a bore with a different offset with respect to the conical axis of the sleeve. The prosthetist selects the appropriate sleeve based upon a prior determination using a temporary pylon and an alignment adapter. The correct foot wedge sleeve and circumferential alignment of the wedge sleeve are set with the aid of discs having offset holes.

摘要： 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.

摘要： 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. The centering axle is thus movable against a biasing force of a spring to disengage the gear from the lock pin.

摘要： An impact reducing prosthetic pylon has a distal component which can be attached to a prosthetic foot and includes a housing within which the proximal component can slidably fit. A resilient bumper-like member formed of a foam is positioned within the housing and is compressed by the proximal component when the prosthesis is under a load. Relative rotation of the proximal and distal components is prevented, but a limited, resiliently damped rotation may be permitted.

摘要： An artificial foot includes a hollow, rigid, compression-molded composite keel made from aramid fiber-reinforced plastic for connection to a prothesis and to an improved composite carbon-fiber material acting as a spring for improving the energy absorbing and releasing characteristics of the foot to aid movement of the amputee. The spring includes a pair of thin, forwardly-extending composite spring members capable of lateral movement with respect to each other and connected to the keel. An auxiliary deflection spring or plate is interposed between the primary deflection plate and the keel and includes a forwardly-extending upwardly-oriented portion to aid in energy absorption and release during flexing of the foot. The plates are surrounded by a suitable abrasion resistant material, such as a Kevlar sock, surrounded by a low density flexible foam urethane. A medium density flexible foam urethane wedge is interposed beneath the heel portion of the keel. The composite construction is surrounded by an outer shell formed in the shape cosmetically to resemble a foot. The keel structure and method of making the composite to provide longitudinal and transverse strength are also disclosed.

摘要： 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. At least one toe spring is connected between the collar and the toe portion of a foot plate, while a heel spring is connected between the heel portion of the foot plate and another end of the pylon.

摘要： A system and method for releasably securing a prosthetic limb to a residual limb. The system and method utilizes a lanyard for drawing the residual limb into a receiving portion of the prosthetic limb and for helping to maintain attachment of the prosthetic limb to the residual limb. The lanyard is routed through a releasable ratchet mechanism, which allows tension to be incrementally applied to the lanyard and further prevents the lanyard and the residual limb connected thereto from moving in an opposite direction. A suction cup may also be employed within the receiving portion of the prosthetic limb for aiding in retention of the residual limb. The ratchet mechanism allows the system to be used without maintaining constant tension on the lanyard, thereby reducing the amount of effort required of the user. The system and method also reduces or even eliminates pistoning of the residual limb within the prosthetic limb during movement of the user.
