Description
Technical Field
The utility model relates to the technical field of robots, in particular to a finger rehabilitation robot.
Background
With the rapid development of modern science and technology, the living standard of people is greatly improved, but the problem of aging of people is accompanied. In the aging population, there are many patients with stroke. Cerebral apoplexy (CVA), also known as stroke, is a general term for a group of acute cerebral circulatory disorders caused by different causes (spasm, obstruction or fragmentation) that can cause a persistent local neurological deficit in the hemispheres or brainstems. Stroke is one of the major causes of damage to the finger nerves. The incidence, disability rate and fatality rate of the cerebral apoplexy are extremely high. Stroke is a sudden disorder of cerebral blood circulation, and the main clinical symptoms of the stroke are the loss of the ability of a patient to control movement with consciousness, such as hemiplegia, facial paralysis, language disorder and the like, and the hemiplegia is the most common symptom of stroke patients. And survey shows that: about 55% -75% of stroke patients leave the problem of limb movement dysfunction, finger movement dysfunction accounts for more than eight of the stroke patients, wherein only about 30% of the stroke patients can completely recover the finger movement function, and the recurrence rate of the stroke patients reaches 25% within two years and 75% within four years. In recent years, with the continuous development of modern rehabilitation technology, although the death rate is greatly reduced, the disability rate is still high, and the recurrence rate is also high.
The rehabilitation robot is one of the important components of the medical robot and is the perfect combination of rehabilitation medicine and related robot technology. The device is an auxiliary device for helping a patient to recover the shape or function of the patient or an organ after trauma or disease, the research content relates to a plurality of disciplines, such as rehabilitation medicine, biomechanics, mechanical engineering, electronic and electrical engineering, computer science, human engineering, robots, control science and the like, and the research has important practical significance. The finger rehabilitation robot is a robot technology, takes clinical rehabilitation medicine as a theoretical basis, completes rehabilitation treatment of patients with finger dyskinesia by assisting or completely replacing doctors, reduces the disability rate of limb dysfunction, and simultaneously has the function of recovering the movement ability of the patients; the living ability and the satisfaction degree of the health care product are improved; the high manual nursing cost is reduced; social resources are saved, and the like.
With the development of scientific technology, the development speed of the finger rehabilitation robot is remarkable. The current situation of hand rehabilitation robots at home and abroad is researched, and the research level at home and abroad has certain gaps, but the gaps are continuously reduced. So far, the research on exoskeleton finger rehabilitation robots at home and abroad has achieved a few achievements, but still has some problems. The following list of several existing problems in the current phase of research:
(1) the portability is low. The driving and executing structure of the rehabilitation robot is too complex, the size is large, the portability is poor, and the safety and the comfort are also to be improved.
(2) The cost is high. The existing finger rehabilitation robots in the market mostly adopt expensive motors and sensors, so that the cost of the finger rehabilitation robot is high, and the finger rehabilitation robot cannot bear the cost at all by ordinary families.
(3) Is bulky. The finger rehabilitation robot is mostly fixed on the base, has large volume, can not be used in a family, can only be used in a hospital or a rehabilitation center, and a patient needs to go to the rehabilitation center regularly to do rehabilitation treatment, thereby reducing the rehabilitation effect.
(4) The safety is poor. In the research results at home and abroad, most exoskeleton finger rehabilitation robots are of pure rigid structures, but the rigid structures are easy to cause secondary damage to patients, and are not beneficial to the development of the robots.
(5) The rehabilitation training movement mode and the training process are single. The rehabilitation training mode is limited to the flexion/extension of the fingers, the realization of abduction/adduction of each finger is lacked, the training process is monotonous and boring, and the initiative of exciting the active movement idea of a patient and participating in training are not facilitated.
(6) The accuracy is not high enough. The mechanical structure and control system of the rehabilitation robot need to be improved, and the parameters such as the angle of the finger joint, the moment of the joint, the speed of the joint and the like of a patient are not accurately controlled in real time in the rehabilitation training process.
In the market, most foreign continuous passive exercise equipment aims at simple rehabilitation training of knee joints, elbow joints and shoulder joints, and relatively less rehabilitation equipment for more complicated finger joints is mainly caused by the complexity of human fingers and palms and the flexibility of human hands. Some devices suitable for finger recovery treatment appear in the domestic market at present, but the price is high, but the devices cannot realize accurate control and cannot adjust the state of a patient in the rehabilitation process.

The passive mode is driven by a rehabilitation exercise method mechanically set according to a program, the power-assisted training mode and the active training mode are mainly manually operated, and the sensors, the motor and the exoskeleton are auxiliary training methods. Based on the requirements of clinical finger rehabilitation training contents, three modes are adopted to carry out rehabilitation therapy training on the affected hand, and the finger rehabilitation training device is suitable for patients in different recovery stages.
A passive training mode: the fingers of a patient in the soft paralysis stage can hardly move autonomously, and the passive training mode is not greatly different from a dead hand, and is just suitable for the affected hand at the stage. During the training process, the fingers of the patient are moved by the traction mechanism at a constant speed according to a fixed track in a natural and relaxed state.
A power-assisted training mode: the training mode is suitable for a patient with certain primary autonomous movement ability, and the rehabilitation device mainly plays a role in assisting correction and helps the affected hand to perform stretching exercise training on a correct track.
