[0002] Due to diseases or other reasons, the hand function is lost, the hand has no support, the fingers are always together, and without functional training and protection, it is easy to cause the hand function to be unable to recover, hand disability, and even self-care. The hand function rehabilitation trainer uses the physical properties of the trainer to train finger muscle strength, help improve hand blood circulation, and improve the patient's hand movement and perception ability.

[0003] After searching, a Chinese patent with publication number CN219941723U discloses a hand function rehabilitation trainer, which relates to the field of medical equipment technology, including installing a shell, and controlling the extension and retraction of the telescopic rod in the micro-telescopic device by the control terminal. The utility model dynamically adjusts the training strength of the patient's hand fingers in a timely manner through the mutual cooperation of the control terminal, the micro-telescopic device and the stretching spring, and through the extension and retraction adjustment of the stretching spring. After the parameters are input to the control terminal once through the touch screen, no manual adjustment is required in the later stage, so that the patient can focus on the hand function recovery itself, ensuring that the patient can achieve a good training effect before, during and after the hand function recovery.
