摘要： A prosthetic system includes first and second parts rotatable relative to one another about a joint. The first and second parts are adapted to form at least part of a weight bearing connection between a prosthetic foot and a socket. A pump system includes a pump mechanism operatively connected to the first and second parts. Rotation of the first part and/or the second part about the joint moves the pump mechanism between an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.

摘要： The present invention is directed to an autonomous exoskeleton device that includes one or more actuators, one or more controllers, one or more sensors with one or more unidirectional transmissions. The present invention provides a mechanical joint in parallel with a biological joint. The exoskeleton device preferably includes and electric motor and winch, chain, belt, cam transmission or other mechanism for providing unidirectional force to assist rotation about the biologic joint. Moreover, a controller, a motor angle sensor, joint angle sensor and/or force sensor may be used for additional control and monitoring of the device. The motor may be any type of motor, but is preferably brushless in configuration where its diameter is larger than its length to provide a compact and lightweight exoskeleton device.

摘要： A prosthetic system includes a prosthetic foot having an upper foot element with a concave-forward facing portion and foot portion extending forwardly therefrom. An intermediate foot element is disposed below the upper foot element and has a front portion coupled to the foot portion of the upper foot element. A lower foot element is disposed below the intermediate foot element. A pump system is coupled to the prosthetic foot and comprises a pump mechanism including a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. An arm member is connected to the pump mechanism and operatively coupled to the intermediate foot element. The arm member is arranged to move the pump mechanism toward at least the expanded configuration upon movement of the intermediate foot element relative to the upper foot element.

摘要： A prosthesis, including a prosthetic foot, a prosthetic talocrural joint, a prosthetic ankle pivotally coupled to the prosthetic foot and a four-area bending beam. The four-area bending beam includes a U-shaped or other spring. One end of the spring is mechanically coupled via two of the four areas to the prosthetic foot. The other end of the spring is mechanically coupled via the other two areas to the prosthetic ankle. The spring resiliently resists pivoting of the prosthetic ankle about the prosthetic talocrural joint. The four-area bending beam exhibits an at least approximately constant moment along its length to maximize strain energy density, storing about four times as much elastic energy as a comparable cantilevered beam, thereby providing high stiffness and high range of motion to the ankle. The spring is modular, being easily replaced with another spring exhibiting a different stiffness, ex., to tailor the prosthesis to a user.

摘要： An orthopedic joint device having a lower leg part, a foot part that is arranged on the lower leg part about a swivel axis such that it can be swivelled, at least a first energy store, and a coupling element. The coupling element can be brought into a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the first energy store, and a de-coupling position. The orthopedic joint device also has at least one release element, which can be brought into a release position and a locked position. The energy stored in the first energy store can be released by bringing the release element into the release position.

摘要： A prosthetic device includes an elongate support member of carbon filament material having a first surface, and an adapter. The adapter includes a compressible member, a base portion having a contact surface arranged to contact the first surface of the support member, a cavity sized to receive the compressible member, and a connector portion extending from the base portion and configured to releasably secure the prosthetic foot to a prosthesis, wherein application of a force to the connector portion compresses the compressible member to dampen movement of the base portion relative to the support member until the contact surface contacts the first surface.

摘要： A prosthetic device and related methods includes an elongate support member having a first surface, and an adapter mounted to the support member. The adapter includes a base portion, a movable member, a connector portion, and an adjustment member. The adjustment member is operable to move the movable member relative to the base portion to change an effective length of an interface between the adapter and the first surface of the support member. The connector portion extends from the base portion and is configured to releasably secure the prosthetic foot to a prosthesis.

摘要： Described here are prosthetic systems, devices, and methods of use therefor. Generally, a prosthesis may be configured to set a resistance to rotation of a prosthetic joint based on a phase of gait. The prosthesis may include a first cylinder, a first piston slidable within the first cylinder, a fluid sump, and a fluid circuit. The fluid circuit may include a plurality of interconnected fluid channels having a unidirectional variable-resistance valve and a set of check valves that are configured to provide unidirectional flow through the valve during piston compression and extension.

摘要： Systems and methods of operating a lower limb device having at least a powered joint are provided. A method includes configuring the device to a first state in a finite state model for a current activity mode including a stair ascent mode or a stair descent mode. The method also includes, based on real-time sensor information, transitioning the device between different states in the finite state model when pre-defined criteria for transitioning among the different states are met. In the method, the finite state model for stair ascent includes lifting and swing phases, where the lifting phase includes a powered knee extension and a powered ankle push-off. The finite state model for stair descent includes yielding and swing states, where the swing states include providing a powered plantarflexion of the powered ankle joint and the yielding states include providing a resistive and passive plantarflexion of the powered ankle joint.
