摘要:
A prosthetic foot (10) including a ground-engaging base (20) in the form of a generally planar and resiliently flexible foot bed (22) which extends between two or more platforms (24, 26, 58) to form one or more flexible hinges (28, 50, 52) therebetweeen. The platform include a toe platform (24) a mid-section platform (26) and a heel platform (58). A support shank (30) is disposed above the platforms so as to be generally positioned above an ankle area of the foot. A first spring (34) extends from the toe platform (24) to the support shank (30). A second spring (38, 40) extends from the support shank (30) to the mid-section platform (26). A third spring (46) extends from the support shank (30) to the heel platform (58). Typically, the springs are curvilinear springs.

A prosthetic foot (70) incorporates a foot keel (71) and a calf shank (72) connected to the foot keel to form an ankle joint area of the prosthetic foot. The foot keel has forefoot and hindfoot portions and an upwardly arched midfoot portion extending between the forefoot and midfoot portions. The calf shank includes a downward convexly curved lower end which is adjustably attached at a portion thereof to the foot keel by way of a releasable fastener arrangement which includes a coupling element (73) intermediate the calf shank and foot keel. The coupling element includes a resilient material forming a joint permitting subtalar joint-like motion of the prosthetic foot in gait.

An apparatus for providing a person with stimuli corresponding to an external operation on a sensor of a prosthetic device is used in conjunction with a prosthetic or sensory impaired limb. A lower limb prosthesis includes sensors on a sensor unit (820) located in a prosthetic foot (806), contacts (826-832) in the socket (810) producing stimuli felt on the residual limb, and an electronic unit (824) to adjust and control the magnitude of the stimuli. An upper limb prosthesis comprises a sensor (1718) located in the thumb (1714) of a prosthetic hand (1704), a vibrating motor (1712) generating sensations felt in the residual limb, and an electronic unit (1810) to control the vibrating motor. An apparatus for a sensory impaired limb providing a sense of feel to an impaired body part are constructed in a similar manner.

Various features for improving the performance of prosthetic sport feet are provided. A fairing for a prosthetic sport foot can include foam components that are coupled to the foot and an elastane cover. The fairing is configured to alter the cross-sectional profile of the foot to produce a more aerodynamic shape. A prosthetic sport foot can include a hollow foot member that can be lighter weight and provide improved performance. A prosthetic sport foot can include an adjustable tension strap extending between and coupled to two portions of the foot member. A prosthetic sport foot, such as a prosthetic running foot or prosthetic cycling foot, can include an aerodynamic fairing and a cover. A prosthetic sport foot can have a varying-width profile such that a mid-section of the foot is narrower and a toe portion flares outward.

A prosthetic foot device has an elongate forefoot spring carried by a fastener and suspended between upper and lower bumpers. A heel spring is suspended between an end of the fastener and the lower bumper.

Die Erfindung betrifft ein orthopädisches Fußteil mit einem Unterschenkel-Anschlussteil, einem als Knöchelgelenk (7) wirkenden Drehgelenk (5), mit dem ein Fußteil (10) in Richtung Dorsalflexion und Plantarflexion drehbar mit dem Anschlussteil verbunden ist, mit einer die Drehbewegung um das Drehgelenk (5) beeinflussenden Dämpfungsanordnung (17), mit einer Sensoranordnung zur Erkennung von Aktionszuständen des orthopädischen Fußteils und mit einer mit der Sensoranordnung verbundenen Steuerung, die die Dämpfungsanordnung (17) steuert. Die Aufgabe wird dadurch gelöst, dass die Sensoranordnung einen den Winkel zwischen Anschlussteil und Fußteil (10) messenden Knöchelwinkelsensor, einen auf die Lotrechte bezogenen Absolutwinkelsensor (20) und einen Momentensensor (21) zur Feststellung des Drehmoments am Knöchelgelenk (7) oder einer ein Drehmoment am Knöchelgelenk (7) auslösenden Kraft aufweist.
摘要:
A prosthetic foot has a plurality of curvilinear leaf springs coupled to an attachment member, including a primary curvilinear leaf spring forming a forefoot arc, an elongated curvilinear leaf spring disposed below the forefoot arc, and a secondary curvilinear leaf spring forming a secondary forefoot member. The forefoot arc is laterally bifurcated while the forefoot reinforcement arc is laterally unitary.
摘要:
A prosthetic foot can include a plate-like foot member extending along a longitudinal axis between an anterior end generally corresponding to a toe portion of a foot to a posterior end, and a metatarsal hinge comprising an elongate groove extending between medial and lateral edges of the foot member. The elongate groove can intersect the longitudinal axis of the foot member, and can be positioned along the length of the foot member at a location generally corresponding to a metatarsal region of the foot. The metatarsal hinge can also comprise a plurality of elongate apertures that extend completely through the foot member, or a plurality of recessed channels that extend only partially through the foot member, or a combination thereof.
