    摘要： A prosthetic ankle includes a pair of prosthetic members movably coupled together to allow movement of the pair of prosthetic members with respect to one another. A hydraulic actuator or damper including hydraulic fluid in a hydraulic chamber is coupled to one of the pair of prosthetic members. A hydraulic piston is movably disposed in the hydraulic chamber and coupled to another of the pair of prosthetic members. A hydraulic flow channel is fluidly coupled between opposite sides of the chamber to allow hydraulic fluid to move between the opposite sides of the chamber as the hydraulic piston moves therein. A voice coil valve is coupled to the hydraulic flow channel to vary resistance to flow of hydraulic fluid through the flow channel, and thus movement of the piston in the chamber, and thus influencing a rate of movement of the pair of prosthetic members with respect to one another.

    摘要： An adjustable below-the-knee prosthetic leg, which is connected between a thigh and an artificial foot, comprises a controller, a connecting mechanism, a hydraulic unit, and a shell. The connecting mechanism and the hydraulic unit are pivotally connected to the controller, and the shell is pivotally connected to the hydraulic unit. The connecting mechanism extends into a hydraulic cylinder of the hydraulic unit. The hydraulic cylinder is in communication with a reserve hydraulic cylinder and a brake hydraulic cylinder of the hydraulic unit. The prosthetic leg allows a user to climb up or go down the stairs and walk on uneven ground easily without falling down.

    摘要： A technology for making the sensation at use of prosthetic limbs utilizing a hydraulic cylinder and a spring cylinder as comfortable as at use of those utilizing a pneumatic cylinder and further for improving walk following properties. In particular, the arrangement of drag generating means, such as a hydraulic cylinder and a spring cylinder, per se is specified. Accordingly, the resistance produced by the drag generating means in accordance with an increase of knee angle is increased. The first torque at the first stage of initial period of bend of knee joint, T1, is made small, while the second torque at the second stage of final periodof further advanced bend of knee joint, T2, is made large. As different from conventional ones, T1≤T2, and the load on the hip joint muscle of prosthetic limb user can be reduced.

    摘要： A prosthetic knee provides a single axis of rotation and includes a hydraulic damping cylinder, a microprocessor, and sensors. Based on input from the sensors, the microprocessor selects a flow path within the hydraulic cylinder in order to provide the proper amount of knee resistance to bending for a given situation. The resistance of each flow path within the hydraulic cylinder is manually preset. Changes in gait speed are accommodated by employing a hydraulic damper with intelligently designed position sensitive damping. Moreover, the knee need not be un-weighted to transition from the stance phase to the swing phase of gait. As a result, the knee safely provides a natural, energy efficient gait over a range of terrains and gait speeds and is simpler, less costly, and lighter weight than the prior art.
