<p>A socket system for use in a prosthetic or orthotic artificial limb for amputees, the socket system bexng dynamically activated by weight-bearing loads and variable in response to shear forces imposed by weight-bearing loads. The socket system includes: a liner (30) adapted to engage the residual limb (6); a socket (80); an air wick (40) between the liner and the socket; a sealing sleeve engaging the socket and the residual limb, the sealing sleeve, the outer socket, and the residual limb creating a sealed chamber; and a vacuum source (600) connected to the sealed chamber and creating a vacuum within the sealed chamber. The vacuum source is dynamically activated in response to weight-bearing loads and varies the response of the socket system to shear forces imposed by weight-bearing loads. The socket system also includes a hydraulic pump (380,390) driving the vacuum pump (600) to supply vacuum to the sealed chamber. The socket system may also include hydraulically- activated bladders (900) driven by the hydraulic pump to engage the residual limb (6) to support and protect problem areas on the residual limb and increase stabilizing pressure during weight-bearing.</p> |
