Electromechanical prosthetic arm for multitype of vocational and technical work and object sawing method thereof

Abstract

The invention provides an electromechanical prosthetic arm for multitype of vocational and technical work. The prosthetic arm includes an upper limb body and a bionic hand, and at least one of a reciprocating tool part, a first rotary movement tool part and a second rotary movement tool part; the front end of the upper limb body is provided with an installation position; the bionic hand, the reciprocating tool part, the first rotary movement tool part and the second rotary movement tool part include shells; the two opposite inner sidewalls of the installation position are respectively providedwith slide grooves; the two opposite side surfaces of the shells are provided with slide rails; the slide rails can match the slide grooves; the shells are inlaid with racks; rotatable gears are arranged in the installation position; the gears mesh with the racks and are in coaxial fixing connection with ratchets; and the ratchets match one ends of pawls, and the other ends of the pawls are connected to rotary type electromagnets. A method for using the prosthetic arm to saw objects is also provided.

Description

technical field [0001] The invention belongs to the technical field of artificial limbs, and in particular relates to an electromechanical artificial limb arm for multi-skill occupational technical work and a sawing control method thereof. Background technique [0002] Every year, countless people suffer from physical disabilities due to diseases, accidents, and work-related injuries. The loss of limbs has a great impact on the body and psychology of the patients. For these patients, prosthetics and assistive devices can help them regain limb function. The production process of traditional prosthetics is very complicated, and the appearance and comfort are not very good; and because the prosthetics are highly personalized, the same prosthetics, due to the different parts of the individual amputation, different physical signs, and different needs, the prosthetic assembly is from the structure, type , size will be different. Therefore, there are strict professional skill req...
