Emulation arm

Abstract

The invention relates to an artificial arm, which is especially suitable for the disabled without both arms. A shoulder rest is sequentially hinged with an upper arm, a lower arm and a bracket, a stretching line is used for controlling the flexion and extension of the lower arm, a thumb, a forefinger, a middle finger, a ring finger and a little finger are respectively fixed on the bracket, the upper end of a driving arm of the forefinger is hinged with the middle and lower parts of the second knuckle of the forefinger, the lower end of the second knuckle of the forefinger is hinged with the middle and upper parts of the third knuckle of the forefinger, the upper end of the forefinger is hinged with the upper end of the first knuckle of the forefinger, the lower end of the first knuckle of the forefinger is hinged with the upper end of the third knuckle of the forefinger, and the lower end of the knuckle of the forefinger is hinged with the bracket. The structures of the middle finger, the ring finger and the little finger are the same as that of the forefinger. The inventive artificial arm is only controlled by one stretching line; and has the advantages of pure mechanism structure, simple structure, easy production and maintenance, low cost, easy operation, and convenient use.

Description

Technical field [0001] The invention relates to a simulation arm, which is particularly suitable for disabled persons who have lost both arms. Background technique [0002] It is very difficult for disabled persons who have lost both arms to take care of themselves. Although some activities can be completed with two feet, it is neither elegant nor convenient. For this reason, more developed countries install electromyographic prostheses for the disabled. Although they can improve their self-care ability, their structure is complex, manufacturing and maintenance are difficult, and the cost is high, making it difficult to popularize. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a simulation arm with simple structure, easy manufacturing and maintenance, low cost, and easy popularization. [0004] The technical solution adopted by the present invention to solve its technical problem is: the upper and lower r...
