Artificial upper limb

Abstract

Provided is an artificial upper limb where a labor tool can be installed. A tool base connected with the labor tool is arranged at the palm part of a hand skeleton and provided with a locking device matched with a tool handle. A thumb in fingers is connected with a linkage mechanism. The linkage mechanism comprises a front arm receiving cavity, an upper arm clamping belt, a hollow bolt, a pull rod, a rotating plate, a shaft rod, a hinge arm and a power rod, wherein one end of the rotating plate is fixedly connected with the thumb, the other end of the rotating plate is connected with one end of the pull rod through a tension spring in a hanging mode, the other end of the pull rod is movably connected with a shifting fork at one end of the power rod in a hanging mode, the other end of the power rod is hinged to one end of the hinge arm, and the other end of the hinge arm is fixedly connected with the upper arm clamping belt. The power rod is composed of a pull arm and an adjusting arm which are connected through threads. A rubber cushion is laid between the hand skeleton and the arm receiving cavity. A baffle is arranged on the hand skeleton. Various labor tools can be installed on the artificial upper limb, and physically-challenged people can conveniently live a daily life and participate in labor.

Description

technical field [0001] The invention relates to a human prosthesis, in particular to an upper limb prosthesis. Background technique [0002] Most of the prosthetics used by disabled persons with missing upper limbs only have the shape of the limbs. Although they can make up for the defects in appearance, they do not help the users in their daily self-care and life. Often constrained by the power of the battery, and the grip strength is not easy to control, and the electric prosthesis is expensive, the structure is complex, and the mechanisms are more precisely matched and connected, which cannot withstand large external force impacts, and can only meet general daily needs. Most of the disabled are troubled by the fact that they are not able to gain social recognition through labor. Contents of the invention [0003] The object of the present invention is to provide an upper limb prosthesis capable of installing various labor tools, so as to meet the needs of daily life an...

[0002] Most of the prosthetics used by disabled persons with missing upper limbs only have the shape of the limbs. Although they can make up for the defects in appearance, they do not help the users in their daily self-care and life. It is often restricted by the power of the battery, and the grip strength is not easy to control. Moreover, the electric prosthesis is expensive, has a complex structure, and the coordination and connection of each mechanism is relatively precise. It cannot withstand large external force impacts, and can only meet general daily needs. Most people with disabilities worry about being unable to gain social recognition through labor.
