Description

Technical Field

[0001] The utility model relates to the technical field of prostheses, and in particular to a prosthesis structural component. Background Art

[0002] Prosthesis, also known as artificial limb, refers to artificial limb used to replace limb dysfunction or to conceal limb disability. It is an artificial limb used by amputees to compensate for the partial function of the missing limb. It is suitable for amputees due to disease, traffic accidents, industrial accidents, sports injuries, etc. Prosthesis can be classified according to structure, function, assembly time, amputation site, power source and selected materials, but the commonly used classification method is to classify them according to the amputation site, which are divided into upper limb prosthesis and lower limb prosthesis. They are mostly made of aluminum plates, wood, leather, plastic and other materials, and their joints are made of metal parts. It can be seen that prosthesis belongs to rehabilitation treatment. Prosthesis can also be divided into the following categories according to anatomical site, structure, purpose and installation time: 1. According to anatomical site: divided into upper limb prosthesis and lower limb prosthesis; 2. According to structure: divided into endoskeleton and exoskeleton prosthesis; 3. According to purpose: divided into decorative prosthesis, functional conventional prosthesis and special-purpose prosthesis (such as work and sports prosthesis, etc.); 4. According to installation time: divided into temporary prosthesis and formal prosthesis

[0003] With the emergence of new technologies and new materials, the design and manufacture of prostheses are increasingly focusing on the need for lightweight prostheses. Various composite materials have begun to be widely used in the design and manufacture of prostheses. At present, the application of carbon fiber in prostheses is mainly to use its unidirectional tensile properties to achieve elastic deformation, especially for the lower limbs, such as carbon fiber feet. Better elastic deformation can achieve a certain energy storage capacity, making patients move more lightly.

[0004] A Chinese patent discloses a new prosthetic structure with the publication number CN 218943614 U. The article states that it "comprises: a structural member body and a metal connector; wherein the metal connector includes a rigid connecting end and an embedding end for fixedly connecting to the structural member body, and the structural member body is formed with a cavity that cooperates with the embedding end; the structural member body is made of lightweight non-metallic material; the new prosthetic structure of the utility model is mainly composed of a small number of metal parts and a large amount of carbon fiber, thereby achieving lightweight prosthetic structure while meeting strength and rigidity requirements." However, in the prior art, when using the prosthesis, the prosthesis is directly put on the leg without fixing the prosthesis. In this way, the prosthesis cannot fully follow the user's walking range when the user walks, which makes it inconvenient to use. Therefore, it is very necessary to design a prosthetic structure.
