Abstract:
A prosthetic limb alignment assembly for positioning a connector at a desired location between a prosthetic socket and a prosthetic limb, comprising:a rotational positioning module having a base attachable to the socket, a body moveably attached to the base, and a locking assembly coupling the body to the base, the locking assembly allowing rotation between the body and the base in a released position for aligning an adjustment axis along the body with the desired location for the connector, and the locking assembly selectively preventing rotation between the body and the base in a locked position, wherein the base comprises a plate configured to be attached to the socket, a first locking element, and an annular wall projecting from the plate, the annular wall having an exterior surface with a plurality of external threads and an interior surface defining the first locking element, wherein the body is configured to be received within the annular wall and has an elongated slot extending along the adjustment axis and a sidewall defining a second locking element configured to engage the first locking element of the base, and wherein the locking assembly comprises a lock-ring with a plurality of internal threads to engage the external threads on the annular wall and a rim projecting inwardly to engage the body as the locking assembly is threaded onto the base, the locking assembly holding the body against the base; andan axial sliding unit attached to the rotational module, the sliding unit having a slider block slidably attached to the body to translate along the adjustment axis, a mounting surface on the slider block to which a connector may be attached, and a fastening mechanism to releasably attach the slider block to the body, the slider block being translated along the adjustment axis to position the mounting surface at the desired location.
