Rigid-flexible exoskeleton hand function rehabilitation device manufactured by flexible material 3D printing

Abstract

A rigid-flexible exoskeleton hand function rehabilitation device manufactured by flexible material 3D printing comprises a bending actuator bonded to a glove module by a hook and loop. An abduction actuator is fixed between fingers of the glove module by sewing, the glove module is worn on the hand of a patient, the bending actuator and the abduction actuator are connected to a control system andan air compressor through air pipes, and the bending actuator and the abduction actuator are manufactured by using 3D printing. The air compressor controls to introduce pressurized gas to the bendingactuator, and the bending actuator drives the fingers to perform stretching exercise. The air compressor controls to introduce the pressurized gas to the abduction actuator, and the abduction actuatordrives the fingers to perform adduction exercise. The device not only satisfies the requirements for bending of finger joints and finger abduction range, but also meets the force requirements of thepatient for daily activities. In addition, 3D printing manufacture improves the manufacturing efficiency and simplicity.

Description

technical field [0001] The invention relates to the technical field of human body movement rehabilitation, in particular to a rigid-flexible exoskeleton hand function rehabilitation device manufactured by 3D printing of flexible materials. Background technique [0002] 80% of stroke patients have left upper limb or hand motor dysfunction, which is characterized by the patient's muscular and skeletal system intact, but the central nervous system is damaged, and the patient's hand function can be restored or improved through appropriate rehabilitation training. Continuous passive movement (CPM) theory has been shown to be useful in the rehabilitation of patients with motor impairment due to neurological damage. However, in traditional rehabilitation treatment, rehabilitation physicians are required to conduct one-on-one treatment, which greatly increases the workload of physicians and rehabilitation costs, and cannot guarantee the efficiency and intensity of rehabilitation tra...

AI Technical Summary

Problems solved by technology

There are deficiencies in the existing hand function rehabilitation equipment: In terms of structure, the rigid equipment has high structural complexity and poor applicability, and some equipment has potential safety problems. It is difficult for flexible equipment to realize hand bionic movement and control; The manufacturing method of flexible actuators is mainly based on casting molding, which has complex procedures, slow molding, and high cost; in terms of rehabilitation functions, most of the equipment can only realize the auxiliary function of finger bending, without assisting the abduction of fingers
