    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 palm unit for an artificial hand comprises: a palm unit body (70); a motor (68) held by the palm unit body (70); a hydraulic pump assembly (72) held by the palm unit body (70) and comprising a low-pressure hydraulic pump (76) and a high-pressure hydraulic pump (74), wherein both hydraulic pumps (74, 76) are powered simultaneously by the motor (68); and a hydraulic circuit held by the palm unit body (70) and coupled to both hydraulic pumps (74, 76), wherein the hydraulic circuit has a low-pressure configuration in which the discharge sides of both hydraulic pumps (74, 76) a re coupled to one or more hydraulic actuator(s) (36, 38) for the artificial hand and a high-pressure configuration in which the discharge side of the low-pressure pump (76) is isolated from the hydraulic actuator(s) (36, 38) and recirculates fluid to the suction side of the low pressure pump (76) with the discharge side of the high-pressure pump (74) remaining coupled to the hydraulic actuator(s) (36, 38), and wherein the hydraulic circuit is arranged to switch from the low-pressure configuration to the high-pressure configuration automatically during a closing grip pattern when the pressure in the system increases beyond a threshold value.

    摘要： A prosthetic 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 prosthetic joint and a method of controlling dorsiflexion and plantarflexion of the hydraulic prosthetic ankle joint. The method includes generating ground reaction forces with a hydraulic prosthetic ankle, wherein the prosthetic hydraulic ankle comprises a first chamber and a second chamber, and the ankle is connected to a prosthetic foot; rotating the prosthetic foot in response to the ground reaction force; transferring fluid between the forward and rear chambers in response to rotation of the foot; providing a feature to occlude or partially occlude the fluid transfer between chambers; providing a non-electronic mechanism for controlling the flow responsive to both a position of the joint and a rate of change of position of the joint, and wherein the mechanism is arranged such that a dwell at a particular joint location or locations will occlude the flow path.
