Abstract

The invention discloses a modular multimodal artificial hand, which comprises a wrist driving module, a palm module, a finger structure, a thumb module, a rope, a rotating winch, a mode conversion module and an adjustable fixing rod, wherein the rope is pulled by the palm flexion of a patient's wrist, the bending of the finger structure is realized, and the stretching is realized by the resilienceof a flexible hinge; using the cam of the modal conversion module to adjust the stretching amount of the rope, the working gesture of the artificial hand can be converted. The working gesture includes grasping, finger and V-shape gesture, which can meet the needs of the daily life of the patients. By changing the winch, the different length of the driving part rope and the finger part rope can bechanged, and the effect and strength of the grasping can be improved. By setting the thumb rotation structure, the degree of freedom of the thumb is increased, and the practicability and the applicable scene of the artificial hand are improved. The invention adopts 3D printing manufacture, is easy to process, simple and portable in structure, low in wearing pressure, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a modular multimodal prosthetic hand. Background technique [0002] As the global population increases and the number of natural disasters and accidents continues to increase, the number of physically disabled people in our country is also increasing. According to the total population of my country in the sixth national census, the proportion of disabled persons in the total population of the country and the proportion of various types of disabled persons in the total number of disabled persons in the second national sample survey of disabled persons, the total number of disabled persons in my country at the end of 2010 is calculated. The population is 85.02 million, of which 24.72 million are physically disabled. Therefore, the demand for prosthetic hands for amputee patients is also increasing, and the design of prosthetic hands suitable for amputee pat...
