Prosthetic foot with a return mechanism

Abstract

The utility model pertains to the field of medicine, specifically orthopedic devices and lower limb prosthetics, and is intended to replace a patient's missing foot. Known foot prosthetic designs may incorporate hydraulic, electropneumatic, and servo-driven systems, as well as elastic and damping elements. However, such designs can be complex and involve a large number of interacting components, complicating their manufacture, operation, and maintenance. The technical result of the claimed utility model is to ensure smooth movement of the movable toe section of the foot prosthesis and its return to its original position after the load is relieved by using a return mechanism. A foot prosthesis with a return mechanism consists of a main supporting frame, an upper part of the movable platform, a lower part of the movable platform, a pyramidal adapter, an elastic platform, and a return mechanism with a spring and damper. The pyramidal adapter is mounted on top of the main supporting frame. The upper and lower parts of the movable platform form the movable toe section of the prosthesis. The return mechanism is installed between the main supporting frame and the upper part of the movable platform, with one end connected to the main supporting frame and the opposite end to the upper part of the movable platform. When a load is applied, the return mechanism ensures elastic movement of the movable nose section of the prosthesis, and after the load is relieved, it returns to its original position.
