Wearable outer limb finger for stroke patient

Abstract

The invention provides a wearable outer limb finger for a stroke patient. A binding module is arranged on the bottom face of a base, a motor module is arranged on one side of the upper end face of the base, a finger module is arranged on the other side of the upper end face of the base, the finger module is bent towards the outer side of the base when a traction module is tensioned by the motor module, and the finger module resets towards the inner side of the base when the traction module is loosened. According to the limb finger, good enveloping is achieved through bending of all knuckle pieces, an object can be stably grabbed, the motor module has the function of feeding back the rotating angle and damping data, the knuckle pieces are provided with force control sensors, and the motor module, the force control sensors and the control module are matched with one another, so that good feedback control is achieved, and an object can be prevented from being damaged by excessive bending.

Description

Technical field[0001]The present invention belongs to the field of rehabilitation upper limb structure, in particular, involving a stroke patient wearable outer limb finger.Background technique[0002]In the field of rehabilitation, traditional robotic adjuvants include prosthetic and outer skeletons, which will have some negative impact on soft tissue and joints during long-term use; the outer limbs are used as an emerging vitality integrated robot, which is different from outside Bones and prosthesis can improve human capabilities or assisted patient rehabilitation by increasing wearable mechanical arms or fingers without replacing natural limbs.[0003]During the patient's rehabilitation, the outer limb finger is applied to help stroke patients, and the upper limb rehabilitation training. At the grabbing phase, the patient wears the outer limb finger and causes the outer limb finger to bend the outer limb finger by an electromyophilic or brain electricity, and is thus the body finger...

AI Technical Summary

Problems solved by technology

In the existing technology, the rigidity of the fingers of the outer limbs is too large, which cannot completely envelop the object well, and the object will fall due to the weak grip, and the stability of the grasp will be poor due to the different size and shape of the object

In order to avoid the problem of poor grasping compatibility of external limb fingers in stroke patients during rehabilitation training, it is necessary to develop a new type of modular flexible external limb fingers
