More Information
Summary:A device is provided to lock the residual limb of an amputee into a prosthesis. The device is comprised of rolling elements within a tapered housing which accepts a smooth plunger, such as a wire, cable, or rod connected to a suspension sleeve, with minimal resistance while opposing removal of the plunger from the locking device until the rolling elements have been retracted with a release mechanism. The nature of this device allows it to compensate for irregularities or wear in the plunger while continuing to securely lock the prosthesis to the sleeve. This locking device will function properly with a certain amount of misalignment between the lock and the plunger.
