Abstract

The invention discloses a flexible underactuated finger rehabilitation device. The device comprises a base, the base is detachably provided with a hand back wear assembly and a motor assembly, the hand back wear assembly is rotatably connected with a thumb wearing component, an index finger wearing component, a middle finger wearing component, a ring finger wearing component and a little finger wearing component, and an underactuated device body is electrically connected to the thumb wearing component, the index finger wearing component, the middle finger wearing component and the ring fingerwearing component; each wearing component includes a joint fixing member and a flexible joint connector, and each joint fixing member is detachably connected to the corresponding flexible joint connector. The device is simple in structure, lightweight and easy to use and adjust.

Description

technical field [0001] The invention relates to a finger rehabilitation device, in particular to a flexible underactuated finger rehabilitation device. Background technique [0002] Hand crushing and smashing are one of the common diseases of hand trauma. After internal fixation of multiple metacarpal fractures, external fixation with plaster should be performed for a period of time to prevent fracture displacement. department function. Clinically, the early postoperative exercise arrangement is 2-3 days after the operation, that is, the passive flexion and extension exercise of the patient's hand is performed, and the patient is instructed to perform active flexion and extension exercise one week later. During the patient's rehabilitation process, rehabilitation training is an essential process to restore hand function. Early rehabilitation treatment can promote the growth of granulation tissue, promote fracture healing, soften scar tissue, and improve joint mobility. Re...
