Rehabilitation mechanical hand with independently adjustable distances among fingers and detachable five fingers

Abstract

The invention discloses a rehabilitation mechanical hand with independently adjustable distances among fingers and detachable five fingers. The rehabilitation mechanical hand comprises a palm part anda finger part, wherein the finger part comprises four finger structures and a thumb structure, and each of the thumb structure and the finger structures comprises proximal metacarpal bone, an MCP joint, a first phalanx and a PIP joint; a connecting plate I is arranged at the tail end of the proximal metacarpal bone of the thumb structure, and longitudinal sliding chutes are arranged in the connecting plate I; an I-shaped connecting plate II is arranged at the tail end of the proximal metacarpal bone of each finger structure; the palm part comprises a palm bottom plate, a palm adjustable baseand a thumb connecting guide rail; arc-shaped sliding grooves and clamping grooves are arranged in the palm adjustable base; the thumb connecting guide rail tallies with the longitudinal sliding chutes in the connecting plate I; the connecting plates II are arranged in the arc-shaped sliding grooves and the clamping grooves; and each of the MCP joint and the PIP joint is composed of a plurality ofgroups of meshed gears. For the rehabilitation mechanical hand with the independently adjustable distances among fingers and the detachable five fingers, the distances among the fingers are adjustable, the fingers can be independently detached, then different objects can be adapted, meanwhile, the disassembly is convenient and rapid, and thus the mounting and maintenance are facilitated.

Description

technical field [0001] The invention belongs to the field of rehabilitation medical equipment, and in particular relates to an autonomously adjustable and detachable rehabilitation manipulator, which is especially suitable for hand rehabilitation training of limb paralyzed patients of different age groups. Background technique [0002] In recent years, there are about 24.12 million physically disabled patients in my country due to brain injury ((stroke, cerebral palsy, traumatic brain injury, brain tumor)), various accidents, polio and other reasons, and more than 10 million people with limb paralysis People, including people of various age groups, especially the elderly and children. With the acceleration of the aging of our country, the number of victims of elderly hemiplegia caused by cerebrovascular diseases is also increasing. The one-on-one rehabilitation treatment of professional medical staff is far from meeting the needs, and the economic burden brought by profession...

AI Technical Summary

Problems solved by technology

[0003] Most of the wearable exoskeleton rehabilitation manipulators currently developed have the following deficiencies: ①The palm size, finger spacing and finger length of most manipulators are fixed, but each person’s palm size, finger spacing and finger length are different, especially The hands of the elderly and children are very different, which cannot meet the needs of patients of all ages; ②Most manipulators have less degrees of freedom and cannot achieve the natural bending of multiple joints of fingers; ③Most manipulators only realize the movement of a single finger or some fingers Rehabilitation, unable to achieve overall hand rehabilitation
