Coupling-socket adapter assembly for a prosthetic limb

摘要

A coupling-socket adapter assembly for a prosthetic limb. A base plate subassembly is attachable to a first prosthetic limb component. A coupling-socket adapter is rotatably attached to the base plate subassembly and has a cavity for receiving a male coupling member (such as a boss of a pyramidal link-plate). Various mechanisms, including a ring having internal threads and including a ring-clamp, are disclosed for locking the coupling-socket adapter against rotation with respect to the base plate subassembly and for unlocking the coupling-socket adapter for rotation with respect to the base plate subassembly, wherein the mechanisms are operable when the base plate subassembly is attached to the first prosthetic limb component.
