摘要： The invention provides for an improved disarticulated compression socket configured to secure a residual limb. The disarticulated compression socket may include a rigid socket frame, and preferably a 3-D printed socket having one or more surface channels that may secure a compression cord optionally positioned within a cord cylinder. Such compression cord may be responsive to a compression actuator and one or more disarticulated compression inserts such that activation of the compression actuator causes the retraction of the compression cord initiating the coordinated inward compression of each of said disarticulated compression inserts securing the residual limb within said socket frame.

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： A hydraulic valve assembly includes a valve core with one or more valve core ports, the valve core rotatably housed in a valve sleeve having one or more valve sleeve ports. A hydraulic resistance of the hydraulic valve assembly varies approximately linearly with a change in valve position caused by rotating the valve core relative to the valve sleeve to vary an alignment between the one or more valve core ports and one or more valve sleeve ports. The valve assembly optionally includes a motor coupler and a gearmotor, the gearmotor operable to rotate the valve core relative to the valve sleeve via the motor coupler.

摘要： A prosthetic device includes an articular actuator assembly including a reduction gearbox that includes an actuating part connected to an output of the reduction gearbox and an actuated part integral with a distal portion of the prosthetic device. The actuating part and the actuated part are provided with abutment and reciprocal fitting. The abutment surfaces are provided on at least one protrusion of the actuating part and on at least one protrusion of the actuated part. In a decoupled condition the protrusion of the actuating part is positioned angularly, spaced from the protrusion of the actuated part and constitutes an end stop for the extension of the distal portion and allows free flexion of the distal portion. In a coupled condition the protrusions are in abutment with each other and actuate the relative rotation of the distal portion with respect to a proximal portion of the prosthetic device in extension.

摘要： The present disclosure provides for a device and method of control for an artificial prosthetic knee. A prosthetic knee according to the present disclosure relies on strictly passive means of providing support during weight bearing and supplements a resistive swing-phase mechanism with a small powered actuator. This actuator adds power to the knee, exclusively during swing phase, to improve swing-phase behavior. In particular, the knee still relies on the resistive swing-phase mechanism to provide nominal swing-phase knee motion, but supplements that motion as needed with the small powered actuator.

摘要： The present disclosure relates to variable recruitment actuator systems and related methods. In one embodiment, a variable recruitment actuator system utilizes a central hydraulic pump, an accumulator, a plurality of variable recruitment actuators, and a pressurized reservoir of hydraulic fluid to provide highly efficient hydraulic regenerative energy harvesting in systems requiring both eccentric and concentric motion. In another embodiment, a powered prosthetic or orthotic device, or a legged robot, utilizes a system as previously described to capture energy from the eccentric motion of the knee joint to provide concentric motion of both the knee and ankle joints later on in a gait cycle.
