Wearable four-finger rehabilitation training device

Abstract

The invention relates to a wearable four-finger rehabilitation training device which comprises a hand support and a four-finger rehabilitation mechanism arranged on the edge of the hand support, wherein the four-finger rehabilitation mechanism comprises more than two finger joint struts which are hinged one another; the finger joint struts are connected with a connection mechanism; a connecting rod mechanism is connected with a force transferring slide block on the hand support; the force transferring slide block is arranged on the hand support in a sliding manner; and a driving mechanism is used for driving the force transferring slide block to move on the hand support, and is linked with the finger joint struts to rotate around an articulated shaft. The hand to be rehabilitated is put on the rehabilitation training device, and then the device is capable of imitating bending, stretching and other swing actions of four fingers of a patient, so that the fingers of the patient can be rehabilitated. The four-finger rehabilitation mechanism is capable of imitating four fingers swinging in a space under the connecting action of the connecting rod mechanism to ensure the rehabilitation effect of the four fingers and the thumb; and the manipulator has a high automatic degree and has an excellent popularization value in the rehabilitation field.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training equipment, in particular to a wearable four-finger rehabilitation training device. Background technique [0002] Up to now, there are about 20 million patients with hand disabilities in my country due to various accidents, hemiplegia, cerebral palsy, polio and other reasons. Weakness in grasping etc. Correction by surgical treatment often fails to achieve the desired effect. Furthermore, the cost of surgery is high and postoperative recovery is not obvious. Many patients do not undergo surgical treatment and enter relevant rehabilitation centers for rehabilitation and correction. In addition, hand damage has a high disability rate, which seriously affects the patient's ability to live and family burden. At present, patients generally use special rehabilitation machines for recovery training in rehabilitation centers, but the disadvantage is that the training time is not enough, and...

Problems solved by technology

Surgical correction often fails to achieve the desired effect. Furthermore, the cost of surgery is high and postoperative recovery is not obvious. Many patients do not undergo surgical treatment and enter relevant rehabilitation centers for rehabilitation and correction.

In addition, hand damage has a high disability rate, which seriously affects the patient's ability to live and family burden. At present, patients generally use special rehabilitation machines for recovery training in rehabilitation centers, but the disadvantage is that the training time is not enough, and it is time-consuming to carry out related rehabilitation. Insufficient doctors and increasing the financial burden on the patient's family, various factors are extremely unfavorable for the patient's recovery

[0003] In this regard, the name of the applicant's application on the same day is "Wearable Rehabilitation Training Exoskeleton Manipulator", which discloses a mechanical device that can be worn on the hands of rehabilitation patients. Link the actions of the four-finger rehabilitation mechanism and the thumb rehabilitation mechanism to achieve the purpose of rehabilitation training. In order to ensure the effect of the four-finger rehabilitation training, it is necessary for the four-finger rehabilitation mechanism to be able to swing within the range of space in order to ensure the effect of the four-finger rehabilitation training. , in the actual design of the four-finger rehabilitation mechanism, there are major technical difficulties
