A Rigid-Flexible Coupling Dexterous Prosthetic Hand

Abstract

The invention relates to a rigid-flexible coupled dexterous prosthetic hand, which includes a main control board and a myoelectric arm ring, a prosthesis cover, a wrist mechanism, a palm mechanism and a finger mechanism connected in sequence. When in use, the myoelectric arm ring and the prosthesis cover Set on the arm, the finger mechanism includes a finger flexion and extension power assembly, a thumb rotation assembly, a four-finger opening and closing assembly respectively arranged in the palm mechanism, and a thumb, index finger, middle finger, and ring finger respectively arranged on the palm mechanism through the finger base. and the little finger, the finger flexion and extension power assembly is respectively connected with the thumb, index finger, middle finger, ring finger and little finger, the thumb rotation assembly is connected with the thumb, and the four-finger opening and closing assembly is respectively connected with the index finger, middle finger, ring finger and little finger Compared with the prior art, the present invention has advantages such as high flexibility.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a rigid-flexible coupling dexterous prosthetic hand. Background technique [0002] With the advancement of industrialization, the number of people with hand disabilities in my country is increasing year by year due to work-related injuries and accidents, which seriously affects the quality of life of these people. Such disabled people usually hope to install prosthetic limbs to partially realize the functions of the real hand, improve the quality of life, and even participate in the work they can do. In recent years, with the rapid development of the economy, robots have also developed rapidly and are widely used in various fields. The manipulator is the final actuator of the robot's work, and its performance directly determines the working ability of the robot. Therefore, the research and development has a high degree of versatility and A dexterous manipulator is necessary. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art that are relatively bulky, easy to loosen after long-term use, make the grip unstable, fingers cannot adapt to the shape of the object when grasping the object, and can only be bent but cannot be opened and closed. Provides a lightweight, adaptive grasp of objects of different shapes, the thumb has a rotation function, and the wrist also has two degrees of freedom and can realize four-finger opening and closing, which effectively expands the rigidity and flexibility of the range of motion of the prosthetic hand.
