A purely mechanical wearable finger prosthesis with multiple degrees of freedom

Abstract

The invention discloses a pure mechanical wearable finger artificial limb with multi-degree of freedom. The pure mechanical wearable finger artificial limb belongs to the field of mechanical structure sports type wearable finger artificial limbs, and comprises a palm part, an index finger stall, a thumb finger stall and other three finger stalls, wherein the connecting relationship of the index finger stall is as follows: an index finger support is hinged to a palm support; the tail end of an index finger proximal knuckle half-stall is hinged to the index finger support; the tail end of an index finger connecting half-stall is hinged to the index finger support; the top end of the index finger proximal knuckle half-stall is hinged to the tail end of an index finger midfinger knuckle; the top end of the index finger connecting half-stall is hinged to the tail end of the index finger midfinger knuckle; the top end of the index finger midfinger knuckle is hinged to an index finger distal knuckle; the top end of the index finger proximal knuckle half-stall is hinged to a hole of an index finger distal knuckle connecting rod; a connecting structure of the index finger distal knuckle is hinged to the hole of the index finger distal knuckle connecting rod. According to the pure mechanical wearable finger artificial limb with the multi-degree of freedom, three degrees of freedom of the thumb finger, two degrees of freedom of the index finger, and one-way degree of freedom of the middle finger, the third finger and the little finger conform to the general use habit of people, and can meet the requirement of daily exercise required by people.

Description

technical field [0001] The invention relates to the field of mechanical structure sports wearable finger prosthesis, in particular to a purely mechanical wearable finger prosthesis with multiple degrees of freedom. Background technique [0002] For disabled people who have lost part of their finger knuckles, especially for those who only have residual knuckle roots, finger prosthetics can help them realize the common functions of their fingers. Today's sporty finger wearable finger prosthetics are mostly in the form of a single degree of freedom, that is, they can only achieve the adduction movement of a single finger. Although most finger movements can be achieved in this way, some more complex movements cannot be realized, such as: gripping, stretching of five fingers, and looping movement of a single finger. Contents of the invention [0003] In view of this, the present invention provides a purely mechanical wearable finger prosthesis with multiple degrees of freedom,...
