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.

摘要： A lower limb prosthesis comprises a foot component and an ankle unit pivotally mounted to the foot component. The ankle unit comprises an ankle joint mechanism comprising a hydraulic piston and cylinder assembly for providing hydraulic damping whenever the ankle joint flexes, and a vacuum mechanism comprising a pneumatic piston and cylinder assembly for generating a vacuum. The hydraulic and pneumatic piston and cylinder assemblies are arranged such that the vacuum mechanism generates a vacuum during plantar-flexion of the ankle unit.

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 self-aligning prosthetic foot and ankle assembly has an ankle unit pivotally mounting a foot component. The ankle unit contains a hydraulic piston and cylinder assembly having a piston which is linearly movable within a cylinder. The axis of the cylinder is coincident with a shin axis defined by a shin connection interface on the ankle unit. Bypass passages containing damping resistance control valves provide continuous hydraulic damping of dorsi and plantar ankle flexion, the unit being such that, over the major part of the range of damped movement, there is no resilient biasing in either the dorsi or the plantar direction. This confers a number of advantages, including stabilization of standing, balance control, and improved stair-walking and ramp-walking.
