Abstract

The invention relates to the technical field of medical care devices, in particular to a low-energy artificial limb comprising a calf artificial limb, an ankle joint and a prosthetic foot plate. The ankle joint comprises two brackets arranged on the top surface on the rear part of the prosthetic foot plate, the two brackets are connected on one side of a swinging device through a rotating shaft respectively, the bottom of the swinging device is connected to the top of the prosthetic foot plate by a spring, and the swinging device is internally provided with a charging conversion device. The charging conversion device converts kinetic energy generated during spring stretching into electric energy and stores the energy in a battery pack. The electric energy stored in the battery pack is usedfor driving the stretching of the spring when the prosthetic foot plate is raised. The low-energy artificial limb can solve the problem in the prior art that the existing artificial limb is poor in comfort, inconvenient to wear and high in energy consumption during work, and a user cannot walk conveniently by wearing the artificial limb.

Description

technical field [0001] The invention relates to the technical field of medical and health care equipment, in particular to a low-energy prosthesis. Background technique [0002] At present, there are many types of ankle joint prostheses on the market, mainly passive ankle joint prostheses, motor-driven active ankle joint prostheses, etc. The passive ankle joint prosthesis uses rubber, carbon fiber and other materials to make the foot plate, or introduces energy storage devices such as springs into the structure to make the whole foot have a certain elasticity. The passive ankle joint prosthesis has the advantages of simple structure, light weight, and low energy consumption. Passive ankle prostheses have no power source, and there is a problem that amputee walking does not match the trajectory of normal limbs; active ankle prostheses introduce active drive devices such as motors into the prosthesis structure. The main advantage of active ankle prostheses is that the wearer's...
