Carbon fiber energy storage pseudarthrosis prosthetic feet

Abstract

The invention relates to a carbon fiber energy storage pseudarthrosis prosthetic foot, comprising an S-shaped upper plate, a lower plate and a connection structure. The invention is characterized in that: the invention also comprises a heel spring strip and a trapezoidal bathtub construction, the upper end of the trapezoidal bathtub construction is horizontal and is fixedly connected with the connection structure, the lower end of the trapezoidal bathtub construction slopes at a 30 degree and is fixedly connected with the heel spring strip, the small notch of the bathtub construction goes forward and the bigger notch thereof goes backward and a S-shaped upper plate which penetrates the notches is connected with the connection structure. The upper curved part of the S-shaped upper plate iscombined with the trapezoidal bathtub construction to imitate subtly the transmission performance and micromotion function of intertarsal joints; the lower curved part of the S-shaped upper plate is combined with a toes part of the lower plate to imitate the dorsiflexion of metatarsophalangeal joints. The heel spring strip is provided with a backward opening and the lower part thereof is connected with the lower plate. The invention which can ensure people to stand steadily and walk for poise enjoys high strength, light weight, good elasticity and the like.

Description

technical field [0001] The invention relates to a prosthesis, especially a prosthetic which simulates the force transmission and micro-movement functions of the intertarsal joints and the dorsiflexion function of the metatarsophalangeal joints, enabling the wearer to achieve the best level of comfort in the process of standing upright and walking. Carbon fiber energy storage pseudo-joint prosthetic foot. Background technique [0002] Since the weight of the prosthesis has a direct impact on the energy consumed by the movement of the lower limb amputee patient, it will affect the effect of the patient wearing the prosthesis. Therefore, in the process of designing and manufacturing prosthetic parts, it is necessary to fully consider the functions required by the patient. Whenever possible, choose lower body accessories that are lightweight and reduce physical exertion. As an important component of the lower limb prosthesis, the main function of the prosthetic foot is to suppo...

AI Technical Summary

Problems solved by technology

[0003] At present, the inner skeleton of the prosthetic foot is generally made of wood, rubber, etc., and a few use high-strength, light-weight carbon fiber, but the structural design is not very ideal, and rarely involves the simulation of important joints of the foot other than the ankle joint. It still feels uncomfortable for the wearer to walk

Although some advanced carbon fiber products have been introduced abroad, they are expensive and not suitable for the consumption of amputees, and the structure still needs to be improved.
