Description

Technical Field

[0001] This invention belongs to the field of medical rehabilitation technology, specifically relating to a rehabilitation training device for patients with nerve damage using their palms. Background Technology

[0002] Hand valgus following nerve injury primarily refers to weakened limb muscle strength or limited joint movement, particularly the thumb, caused by damage to brain nerves. This condition is usually related to brain injury and may be due to increased flexor muscle tone. Therefore, rehabilitation requires correcting deformities, increasing joint range of motion, muscle strength, hand dexterity, and coordination to restore hand function and improve quality of life.

[0003] Currently, some hand rehabilitation training devices aim to assist patients in hand rehabilitation. For example, the hand-supported finger rehabilitation training device and its usage method disclosed in patent publication number CN109549819B. During the hand-supported finger rehabilitation treatment, the palm is placed flat in the treatment device. The support of the palm does not put pressure on the wrist, ensuring the intensity of rehabilitation training without causing secondary damage to the wrist or other parts of the body. The device uses force sensors to judge the stability of the force and control the force smoothly, so that the force on the fingers can remain stable, which is convenient for patients' rehabilitation training. At the same time, the device uses a sliding groove structure to reduce the complexity of the device structure. Four motors can realize a large-scale stretching and gripping movement of the fingers, ensuring the rehabilitation effect of the fingers.

[0004] It can be seen that although the device can exercise the joints of the fingers, it also has certain problems. On the one hand, the distance between the various parts of the fingers is basically not adjustable, making it difficult to adapt to different patients. On the other hand, due to the aforementioned lack of adjustability, if the length between the joints of the patient's fingers does not match the device, the device may cause injury to the patient's fingers due to improper stretching during exercise. Finally, the device cannot exercise the thumb, which is most prone to inward turning, so its rehabilitation effect on patients is very limited.

[0005] Therefore, there is a need for a hand rehabilitation training device for patients with nerve damage. The core function of this device is to help patients extend all their fingers, including the thumb, through the expansion of a pull cord, thereby promoting the recovery and enhancement of finger function. In its design, the device must consider the safety of patients during rehabilitation, avoiding finger injuries caused by rigid connections and lack of adjustability. Furthermore, the device needs to possess a degree of flexibility and adjustability to allow for personalized adjustments based on different patients' hand shapes and rehabilitation needs. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention designs a hand rehabilitation training device for patients with nerve damage. The device assists in hand rehabilitation by using a pull cord to stretch the patient's fingers and their joints. Simultaneously, the device avoids using rigid connection mechanisms to exercise the patient's hand joints, preventing improper stretching from causing injury. Furthermore, the elastic band can be adjusted according to the patient's hand shape and size, ensuring a stable and comfortable fit. Finally, the device uses only a single motor to exercise all the joints of the patient's hand, reducing manufacturing and maintenance costs, as well as operation and learning costs.

[0024] In this embodiment, for typical stroke patients with limb dysfunction, the function of the thumb accounts for half of the rehabilitation training for upper limb function. The thumb needs to perform abduction, adduction, rotation, and grasping functions. Therefore, this device can additionally add a rotating component 10, as detailed in the following reference. Figure 6 The rotating component has a built-in motor, which is connected to two pull ropes. The two pull ropes are connected to different positions of the first rotating sleeve 501. By rotating the motor built into the rotating component, the first rotating sleeve can be controlled to rotate back and forth, thereby exercising the rotation function of the thumb. At the same time, when exercising the thumb, it will not affect the exercise of other finger joints.

[0025] The working principle and usage procedure of this device are as follows: When a patient with nerve injury needs to perform rehabilitation exercises on their hand, the patient passes the hand to be exercised through the wrist sleeve 1 and the palm sleeve 201. The wrist sleeve 1 is fixed to the patient's wrist. At the same time, the patient's thumb, index finger, middle finger, ring finger, and little finger are respectively put into their corresponding fingertip sleeves. At this time, under the tension of the elastic band, the fingertip sleeve will be tightened to the patient's fingertip. Meanwhile, the middle sleeve is adjusted so that it is placed on the patient's middle finger joint.

[0026] Next, the winding motor 3 is activated. The first pull rope 504, second pull rope 604, third pull rope 704, fourth pull rope 804, and fifth pull rope 904 inside the hub 4 are combined into a single main pull rope 401, which is connected to the winding motor 3. The function of the winding motor 3 is to control the tightening and loosening of the pull ropes, thereby adjusting the degree of finger stretching. This achieves stretching of the finger joints. Patients can adjust the stretching intensity and duration via the motor according to their rehabilitation needs and comfort.
