Assortment of lightweight prosthetic hands

Abstract

The invention discloses a classification-combination light artificial hand. The classification-combination light artificial hand can be applicable to persons of disabled fingers of different classes, and helps the persons to achieve daily actions to a certain extent such as holding, pinching and bending which can be completed by hands of normal persons. The classification-combination light artificial hand comprises a body module, a movement source module, a thumb module and finger modules. The thumb has the metacarpal bone disability class and the proximal phalanx disability class according to different disability conditions. The four fingers have the metacarpal bone disability class, the proximal phalanx disability class and the middle phalanx disability class. The artificial hand is in modular design, artificial limbs applicable to different conditions fall into different modules, and therefore disassembly, assembly, repair and replacement are facilitated; different control ways are selected for different finger disability conditions, so that little influence is caused by an artificial limb control mechanism on other activities of the hands, and the activities of the hands of the disabled are expanded to the greatest degree; the classification-combination light artificial hand is compact in structure, has the appearance approaching the shape of the hands, and can meet the psychological needs of the disabled.

Description

technical field [0001] The invention relates to a light prosthetic hand, in particular to a classified and combined light prosthetic hand. Background technique [0002] At present, the largest proportion of finger prostheses sold on the market are decorative finger prostheses, that is, prostheses made of silicone, which do not have the function of movement, and due to the need for individual customization and the particularity of materials, the price is relatively high. In the market of finger prostheses, there are only a small proportion of mechanical prostheses, and they are basically imported from abroad. Mechanical prostheses are divided into two types: one is motor-driven, intelligent system processing, mechanical control, Sensor Feedback; Such prosthetics are expensive, heavy, and powerful but have significant limitations. The other is purely mechanical, sacrificing a certain degree of freedom of the hand in exchange for the driving force of the mechanical structure o...

Problems solved by technology

The "X-Finger" invented by the famous doctor Dan Didrick is a purely mechanical prosthesis, but its application space is limited, and it cannot provide solutions for various complicated disability conditions, and it needs nearly thousands of dollars, which is a high cost. The price makes it difficult to access, so that everyone with disabilities can benefit
