The present disclosure is directed to prosthetic limb sockets that couple prosthetic limbs to residual limbs. The sockets include a conical cup sized to engage and couple to the residual limb, and a base to secure the socket to the prosthetic limb. The sockets are direct heat-formable onto the residual limb, such that they can be heated and formed as they are secured to the residual limb.本發明關於將義肢耦合至殘肢的義肢套節。套節包含尺寸可接合並耦合到殘肢的一錐形杯、以及用以將套節固定到義肢上的一底座。套節可直接熱成形到殘肢上，使得它們可在固定到殘肢時被加熱和形成。
