摘要： An artificial foot and ankle joint consists of a curved leaf spring foot member having a heel extremity and a toe extremity, and a flexible elastic ankle member that connects the foot member for rotation at the ankle joint. An actuator motor applies torque to the ankle joint to orient the foot when it is not in contact with the support surface and to store energy in a catapult spring that is released along with the energy stored in the leaf spring to propel the wearer forward. A ribbon clutch prevents the foot member from rotating in one direction beyond a predetermined limit position. A controllable damper is employed to lock the ankle joint or to absorb mechanical energy as needed. The controller and sensing mechanisms control both the actuator motor and the controllable damper at different times during the walking cycle for level walking, stair ascent, and stair descent.

摘要： A prosthetic foot and ankle assembly includes a foot component and an ankle joint mounted thereto and having a fixed range of dorsi-plantar flexion. The ankle joint includes a joint mechanism in the form of a hydraulic linear piston and cylinder assembly having a pair of chambers on opposite sides of the piston to provide hydraulic damping continuously over the range of dorsi-plantar flexion. The joint mechanism further includes a valve arrangement controlling the flow of hydraulic fluid between the chambers. The valve arrangement includes first and second adjustable valves for independently controlling dorsi-flexion damping resistance and plantar-flexion damping resistance respectively. The joint mechanism includes a first flexion limiter that limits dorsi-flexion of the joint mechanism to a dorsi-flexion limit and a second flexion limiter that limits plantar-flexion of the joint mechanism to a plantar-flexion limit, thereby defining the fixed range of dorsi-plantar flexion.

摘要： A knee prosthesis comprises an agonist-antagonist arrangement of two series-elastic actuators in parallel, including a knee joint, flexion and extension actuators connected to the joint in parallel with a leg member, and a controller for independently energizing the actuators to control the movement of the knee joint and leg. The flexion actuator comprises the series combination of a flexion motor and a flexion elastic element and the extension actuator comprises the series combination of an extension motor and an extension elastic element. Sensors provide feedback to the controller. The flexion actuator and the extension actuator may be unidirectional, with the flexion and extension elastic elements being series springs. The extension actuator may alternatively be bidirectional, with the extension elastic element being a set of pre-compressed series springs. Alternatively, the flexion elastic element may be a non-linear softening spring and the extension elastic element may be a non-linear hardening spring.

The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.

摘要： A prosthetic ankle and foot combination has an ankle joint mechanism constructed to allow damped rotational movement of a foot component relative to a shin component. The mechanism provides a continuous hydraulically damped range of ankle motion during walking with dynamically variable damping resistances, and with independent variation of damping resistances in the plantar-flexion and dorsi-flexion directions. An electronic control system coupled to the ankle joint mechanism includes at least one sensor for generating signals indicative of a kinetic or kinematic parameter of locomotion, the mechanism and the control system being arranged such that the damping resistances effective over the range of motion of the ankle are adapted automatically in response to such signals. Single and dual piston hydraulic damping arrangements are disclosed, including arrangements allowing independent heel-height adjustment.
