Rigid-flexible coupling dexterous prosthetic hand

Abstract

The invention relates to a rigid-flexible coupling dexterous prosthetic hand which comprises a main control board, a myoelectric arm ring, a prosthetic sleeve, a wrist mechanism, a palm mechanism and a finger mechanism, and the myoelectric arm ring, the prosthetic sleeve, the wrist mechanism, the palm mechanism and the finger mechanism are sequentially connected. During use, the myoelectric arm ring and the prosthetic sleeve are arranged on the arm in a sleeving manner, the finger mechanism comprises a finger bending and stretching power assembly, a thumb rotating assembly, a four-finger opening and closing assembly, a thumb, an index finger, a middle finger, a ring finger and a little finger, the finger bending and stretching power assembly, the thumb rotating assembly and the four-finger opening and closing assembly are arranged in the palm mechanism, and the thumb, the index finger, the middle finger, the ring finger and the little finger are arranged on the palm mechanism through finger bases. The finger bending and stretching power assembly is respectively connected with the thumb, the index finger, the middle finger, the ring finger and the little finger; The thumb rotating assembly is connected with the thumb, the four-finger opening and closing assembly is connected with the index finger, the middle finger, the ring finger and the little finger respectively, and compared with the prior art, the rigid-flexible coupling dexterous prosthetic hand has the advantages of being high in flexibility and the like.

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 this group of people. Such disabled people usually hope to install artificial limbs to partially realize the functions of real hands, hope to improve the quality of life, and even participate in work within their ability. 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 executive mechanism of the robot's work, and its performance directly determines the working ability of the robot. Therefore, research and development have a high degree of versatility and A manipulator...

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.
