Abstract

Vacuum locking systems for prosthetic limbs are generally disclosed. An example double-wall socket system according to at least some aspects of the present disclosure may include a flexible liner shaped to accept a portion of a residual limb; a plunger pin mounted to a distal end of the flexible liner; an inner socket shaped to receive the flexible liner and the residual limb; an outer socket shaped to receive the inner socket, the flexible liner, and the residual limb; a locking mechanism mounted at least partially within the inner socket approximate a distal end of the inner socket; and a manifold mounted to a distal end of the outer socket. The manifold may be configured to be connected to a vacuum pump for withdrawing air from the double wall socket system.
