Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] like figure 1 Shown is a schematic structural diagram of the hand rehabilitation device of the present invention.

[0037] The hand rehabilitation equipment includes support 2, metacarpal bone plate 1, finger flexible driving mechanism and exoskeleton mechanism. The mechanism is fixedly connected to the metacarpal plate 1, and the exoskeleton mechanism is connected to the finger flexible mechanism. When the linear motor generates linear motion, it transmits the motion to the exoskeleton mechanism through the elastic element, thereby driving the exoskeleton mechanism to drive the patient's fingers to achieve flexion rehabilitation. The bearing 2 and the metacarpal plate 1 can be quickly connected and disassembled.

[0038] The exoskeleton mechanism includes five exoskeletons with the same structure, which are thumb exoskeleton 11, ind...

Abstract

The invention relates to a flexible driving hand rehabilitation device and a feedback control circuit thereof. The device includes a support and a metacarpal bone plate connected with the support; wherein an exoskeleton mechanism is fixedly connected with the metacarpal bone plate and corresponds to the positions of finger joints; a finger flexible driving mechanism is fixedly connected with the metacarpal bone plate; and the exoskeleton mechanism is connected with the finger flexible driving mechanism. The device is suitable for carrying out daily hand rehabilitation training for patients with impaired hand function, the structure is compact, reliability is high, the device is suitable for home rehabilitation training, because of its flexibility, portability and other characteristics, canmeet the needs of patients at home, and through intelligent control, can regulate the training mode of patients to a certain extent, so as to improve the effect of rehabilitation training.

Description

technical field [0001] The invention relates to the field of new service and medical rehabilitation training robots, in particular to a flexible-driven hand rehabilitation device and a feedback control circuit thereof. Background technique [0002] According to statistics, the number of patients with hemiplegia caused by neurological diseases or cardiovascular and cerebrovascular diseases such as stroke, and the number of limb injuries caused by traffic accidents are on the rise. Among them, the impairment of hand function has a negative impact on the daily life of patients. great. Patients with damaged hands need to take medicine or surgery to repair the damaged part in the early treatment, which requires a lot of medical and nursing costs. In the middle and late stages of treatment, some of the hand functions of patients can be restored. In order to save medical expenses, reduce nursing costs, and reduce the work intensity of medical staff, most patients can choose to car...
