Description

Technical Field

[0001] This utility model relates to the field of finger rehabilitation, specifically a finger rehabilitation robot. Background Technology

[0002] Finger rehabilitation robots are devices for training and rehabilitating individual fingers. Through task-oriented functional training and synergistic movement training of the whole finger or a single finger, they effectively improve patients' hand muscle strength, joint range of motion, superficial and deep sensation, finger dexterity and coordination. Through functional training, patients can acquire corresponding daily living abilities and achieve active and passive training modes, making them suitable for the treatment of patients with various muscle strength levels.

[0003] Existing technologies for finger rehabilitation robots still have certain drawbacks. Traditional finger rehabilitation robots rely on a drive module to automatically bend each joint to achieve rehabilitation. This method can lead to finger dependence, and once the finger is removed from the rehabilitation robot, the finger cannot move flexibly, which is not conducive to the recovery of finger muscle strength and results in a relatively slow rehabilitation effect. Utility Model Content

[0004] The purpose of this invention is to provide a finger rehabilitation robot to solve the problem mentioned in the background art that each joint of a traditional finger rehabilitation robot is driven by a drive module to automatically bend in order to achieve the purpose of rehabilitation. This method will make the fingers dependent, and once they are separated from the finger rehabilitation robot, the fingers still cannot move flexibly, which is not conducive to the recovery of finger muscle strength and the rehabilitation effect is relatively slow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a finger rehabilitation robot, comprising a finger rehabilitation robot body, a training intensity enhancement mechanism located on the back of the hand on the surface of the finger rehabilitation robot body, a guide tension rod inside the training intensity enhancement mechanism, a finger support plate at the front end of the finger rehabilitation robot body, a wearable finger sleeve at the fingertip of the finger support plate, a thumb support plate on one side of the finger rehabilitation robot body, a bending component on the outer side of the thumb support plate, a second data connection line at one end of the bending component, and a thumb wearable finger sleeve at the fingertip of the inner side of the thumb support plate. The rear end of the finger support plate is connected to the main body of the finger rehabilitation robot via a fixed ear, and the thumb support plate is hinged to the fixed ear via a first fixed hinge. The rear end of the main body of the finger rehabilitation robot is provided with a wrist sleeve. The main body of the finger rehabilitation robot is located above the base. The surface of the base is provided with a palm support block at the palm position. The front end of the surface of the base is provided with a finger pad. The bottom of the finger pad is provided with a positioning slider. One end of the positioning slider is connected to a support rod. The support rod is located inside an electro-hydraulic rod. One end of the electro-hydraulic rod is provided with a first data connection line. The rear end of the surface of the base is provided with a support base. The bottom of the base is provided with a front rubber anti-slip pad and a rear rubber anti-slip strip in sequence.

[0006] In a further embodiment, the guide tension rod is connected to the finger support plate via a connecting segment, and the connecting segment is hinged to the finger support plate via a hinge.

[0007] In a further embodiment, the finger pad has finger straps on both sides, and the finger straps are fixedly connected to the wearing finger sleeve by buckles.

[0008] In a further embodiment, the finger pad and the base are slidably connected by a positioning slider, the finger pad and the positioning slider are hinged together by a hinge, and the finger pad is designed as a circular structure.

[0009] In a further embodiment, the inner end of the guide tension rod is fixedly connected to the training intensity enhancement mechanism by a strength enhancement spring, and the inner end of the top surface of the guide tension rod is slidably connected to the training intensity enhancement mechanism by a limiting slider and a limiting groove. The rear end of the surface of the training intensity enhancement mechanism is provided with a sealing cover, and the sealing cover is fixedly connected to the training intensity enhancement mechanism by a buckle.

[0010] In a further embodiment, a cable tray is provided between the support and the palm support block, the palm support block is fixedly connected to the base by screws, and the palm support block is designed as a hemispherical structure. A wrist strap is provided on one side of the support, and the wrist strap is connected to the wrist sleeve by Velcro.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the electro-hydraulic rod is located inside the base, separating the drive module from the finger module. The electro-hydraulic rod can serve as an auxiliary tool to traction the bent position of the finger, making it easier and less strenuous for the patient to bend the finger. It utilizes part of the driving force of the electro-hydraulic rod and part of the patient's own muscle strength, not relying entirely on the power of the drive module for bending. The patient also needs to exert force. The combination of these two forces is more conducive to the rehabilitation training of the patient's fingers, shortening the rehabilitation time. Furthermore, an intensity-enhancing spring is installed inside the training intensity-enhancing mechanism. The intensity-enhancing spring serves two purposes: first, it is used to automatically reset the bent finger; second, it is used to increase the intensity of finger bending, which is beneficial to the improvement of muscle strength.
