ABSTRACT:
A prosthetic coupling device for incorporation into a prosthetic socket and for coupling a prosthetic limb structural system to the prosthetic socket includes a deformable urethane cup to receive a positive model of an amputated limb and a coupling plate for attaching the prosthetic socket to prosthetic limb structural system. The deformable cup is flared at an end to allow it to accommodate a wide range of limb sizes. The coupling plate includes a surface for attaching to the deformable urethane cup, threaded standoffs that adjust the thickness of a laminate material formed around the end of the coupling plate during fabrication into a prosthetic socket, an o-ring that secures a sheet of PVA to the coupling plate during fabrication and a centered through hole for connecting to a pin from a suspension sleeve. The prosthetic coupling device may further include one or more magnets for releasably securing the prosthetic socket to a suspension sleeve.
