Abstract:
1. A locking prosthetic joint, comprising: a stator; a rotor adapted to rotate relative to said stator about an axis of rotation, and comprising a plurality of structures essentially regularly spaced around said axis of rotation to define a plurality of spaces between said structures; one or more plungers adapted to releasably engage the spaces between the structures; and a device comprising a cam ring, and a plunger pin coupled to the plunger for moving said plungers from an outward locking position in which one or more plungers are at least in part located in a said space between two of said structures to prevent said rotor from rotating relative to said stator, and an inward free position in which said one or more plungers are free from said structures to allow said rotor to rotate relative to said stator.
