Fixing device for upper limb prosthesis

Abstract

The invention relates to a fixing device for an upper limb prosthesis, used for fixing the upper limb prosthesis to a human body residual limb. The fixing device for the upper limb prosthesis comprises a prosthetic socket, a decompression pectoral girdle used for fixing the prosthetic socket and a socket fastener used for fastening the prosthetic socket on a human body, wherein the prosthetic socket is in a shape of rectangular cover body, can sleeve the human body residual limb and can be in tight contact to the human body residual limb; the decompression pectoral girdle is composed of an axilla decompression pectoral girdle, a thorax decompression pectoral girdle and a waist decompression pectoral girdle; the upper limb prosthesis can be detachably connected with the prosthetic socket; an opening end of the prosthetic socket is tightly connected with a human body residual limb end; and the axilla decompression pectoral girdle, the thorax decompression pectoral girdle and the waist decompression pectoral girdle are all connected with the prosthetic socket and can pass through an axilla, a thorax and a waist of the human body respectively to be connected with the front side and the back side of the prosthetic socket. According to the fixing device for the upper limb prosthesis, the prosthesis can be accurately fixed on the residual limb, so that the upper limb prosthesis is easily worn and taken off.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation aids, in particular to a fixation device for upper limb prostheses used by disabled persons after shoulder joint disarticulation. Background technique [0002] The wearing device of upper limb prosthesis is a common shoulder prosthetic accessory, which can provide additional assistance and protection for the upper limb disabled, and has great significance for improving the quality of life of the upper limb disabled. [0003] Therefore, along with people's growing concern for vulnerable groups, a large number of shoulder prosthetic braces have emerged on the market. [0004] However, after careful study, it was found that these shoulder prosthetic straps have similar forms, and most of them are designed for the shoulder straps, but no research has been done on the wearing and fixing of the upper limb prosthesis, thus lacking the precise positioning design for the prosthesis. [0005] For th...
