Totally closed bionic upper arm prosthesis

Abstract

The invention discloses a totally closed bionic upper arm prosthesis, which is composed of a lower arm drum (1), an electric wrist joint (2), an upper arm drum (3), a decorative strip (4), a baffle cover (5), an elbow joint (6) and an elbow connecting plate (7), wherein the upper arm drum (3) and the lower arm drum (1) are connected by virtue of the electric wrist joint (2); a flange structure (5-1) of the baffle cover (5) is matched with the edge of an arc-shaped notch (3-2) of the upper arm drum; the elbow connecting plate (7) is connected to the upper arm drum (3) by virtue of a bolt (8) and a nut (9); an output shaft of the elbow joint (6) is matched with a boss waist-shaped hole (7-2) in the elbow connecting plate (7); the decorative strip (4) covers the baffle cover (5) and the upper arm drum (3); and cylindrical covers (4-1) at two ends of the decorative strip (4) are matched with two ends of the output shaft of the elbow joint (6). The upper arm prosthesis disclosed by the invention can be used for solving the problem of exposure of electronic circuits, bolts, nuts and the like which is common in the upper arm prosthesis, and can be used for improving the appearance quality of the upper arm prosthesis; and the entire upper arm prosthesis is neat and uncluttered.

Description

technical field [0001] The invention relates to the field of myoelectric and electric control upper limb prostheses, in particular to a fully enclosed bionic upper arm prosthesis. Background technique [0002] With the development of society, various industrial accidents, traffic accidents, earthquakes and other natural disasters continue to occur, and various disabled people continue to appear. How to improve the quality of life and work of these disabled people, especially those who lack upper limbs The quality of life of the disabled is the responsibility of the whole society. The emergence of various artificial limbs has indeed brought great convenience to the disabled, enabling them to live, work and study like normal people. The most practical significance in terms of upper limbs is the prosthetic hand with the function of opening and closing and picking up objects, as well as the elbow joint and wrist joint. [0003] With the development of upper limb prosthetics, th...

AI Technical Summary

Problems solved by technology

In the upper arm prosthesis, many arm tubes are made in the form of vacuum pumping. Due to the limitation of the production process, the aesthetics are not very satisfactory. In addition, due to the problem of the wiring direction in the installation of the elbow joint, electronic circuits are common in many upper arm prostheses. , bolts, nuts and other exposed problems, so the appearance of the upper limb prosthesis is insufficient
