Embodiment Construction

[0032] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0033] Referring to Figures 1 to 5, a person's arm is mainly composed of bones, tendons, tendon sheaths, pulleys and skin. Bones include the phalanges, metacarpals, wrist bones, ulna, and radius. The phalanx is divided into the thumb bone, index phalanx, middle phalanx, ring phalanx, and little phalanx. Except for the thumb bone, which is composed of the proximal phalanx and the distal phalanx, the other four fingers are composed of the proximal phalanx, middle phalanx, and distal phalanx. The metacarpal is made up of five bones. The wrist bone is made up of eight bones, plus the ulna and radius. The entire arm (excluding the humerus of the upper arm) is composed of twenty-nine bones.

[0034] The artificial arm should not only achieve simulation in function, but also be easy to implement and low in cost. The present invention adopts eighteen pie...

Abstract

An artificial hand with multiple functions, no error operation and no complication is composed of such artificial units as finger bones, metacarpal bones, ulna, radius, muscle tendons, tendon sheaths, slide mechanism, muscles and skin. It can be connected to the crippled end of human radius by screw and its artificial muscle tendons can be linked with relative ones of human body by stitch.

Description

technical field [0001] The invention relates to an artificial artificial artificial limb, in particular to an artificial artificial arm suitable for the requirements of patients with upper limb forearm distal amputation. Background technique [0002] At present, it is generally accepted that upper limb prostheses are structurally divided into: (1) decorative hands, which mainly play a cosmetic role and have no function; (2) tool hands, which are poor in appearance and are mainly convenient for labor; (3) functional prosthetic hands, which are aesthetically pleasing, There are fewer functions; (4) myoelectric prosthetic hand, powered by a small electric motor, has a complex structure and a single function. [0003] 1) Although the current artificial limbs are relatively close to the normal limbs of the human body in appearance, they are far from functional. Take the upper limb prosthesis as an example. There are 27 degrees of freedom in the upper limbs of the human body, of ...
