[0002] Since the hand is the part of the human body that comes into contact with the outside world the most and is often injured. Whether it is a cut, a crush injury, a fall, a sprain, or other various forms of injury, as long as the violence is large enough, in addition to causing damage to soft tissues such as the skin, it may also cause damage to bone tissue, manifested in forms such as bone defects in the bones. Hand injury rehabilitation is based on the diagnosis and treatment in hand surgery, and aims at various factors causing hand function disorders, such as scars, contractures, adhesions, swelling, joint stiffness, muscle atrophy, loss or abnormality of sensation, etc. By adopting corresponding rehabilitation means such as physical therapy, exercise therapy, occupational therapy, assistive devices, rehabilitation engineering, and psychological therapy, the injured hand can recover the maximum degree of function to adapt to daily life activities, work, and study.

[0003] A Chinese patent discloses a hand rehabilitation training grip strength device after surgery (the authorization announcement number is: CN221206694U). It rotates by hinging the first grip plate and the second grip plate, which is convenient for the patient to move the palm and fingers. And the palm passes through the first tightening component and the fingers pass through the second tightening component to facilitate holding the first grip plate and the second grip plate. When the fingers bend simultaneously, the first grip plate and the second grip plate fold and move through the telescopic component, training the palm and fingers after surgery, promoting blood circulation, and quickly restoring the sensitivity of the fingers. However, looking at its specification drawings, since the elastic strength of the first spring and the second spring in the above device cannot be adjusted, its application range is limited. And through common sense, different training intensities should be adopted at different stages after hand surgery to be helpful for rehabilitation. Obviously, the above device cannot meet the usage needs of different people and has certain limitations. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 3 , the present invention provides a hand injury postoperative rehabilitation training device, including a base 1. Two fixing blocks 11 are fixedly connected to the front surface of the base 1, and a first baffle 2 and a second baffle 3 are fixedly connected to the top of the base 1. A cross plate 4 is fixedly connected between the first baffle 2 and the second baffle 3.

[0019] A presser 5 is installed on the cross plate 4. The presser 5 includes a worm 51, a worm wheel 52 and a threaded rod 53. The worm 51 is meshed with the worm wheel 52 at the rear side. A threaded rod 53 is fixedly penetrated through the inside of the worm wheel 52. An adjusting plate 54 is sleeved on the outside of the threaded rod 53 in a threaded manner. Four telescopic columns 55 are slidably penetrated through the inside of the adjusting plate 54. Springs 56 and limiting discs 57 are sleeved on the outside of the telescopic columns 55. The tops of the four telescopic columns 55 are fixedly connected with pressing blocks 58. Slots 581 are horizontally opened inside the four pressing blocks 58. Inserting rods 59 are inserted into the slots 581. A groove is horizontally penetrated through the inside of the fixing block 11. The diameter of the groove is larger than the diameter of the inserting rod 59. An anti-detachment disc is also fixedly connected to one end of the inserting rod 59. The adjusting plate 54 is located between the first baffle 2 and the second baffle 3. The adjusting plate 54 and the cross plate 4 are parallel to each other. One end of the spring 56 is fixedly connected to the limiting disc 57, and the other end of the spring 56 is fixedly connected to the adjusting plate 54. The telescopic column 55 and the limiting disc 57 are fixedly connected. The limiting disc 57 abuts against the lower surface of the cross plate 4. One end of the worm 51 penetrates through the first baffle 2, and the other end of the worm 51 is rotatably connected to the second baffle 3 through a bearing. The top end of the threaded rod 53 is rotatably connected to the center of the bottom of the cross plate 4 through a bearing, and the bottom end of the threaded rod 53 is rotatably connected to the center of the top of the base 1 through a bearing.

Moreover, the presser 5 is not only convenient for single-finger pressing training, but also convenient for four-finger simultaneous pressing training, and the applicable range is significantly improved.

[0020] Working principle: When using this device, when single-finger pressing training is required, simply place a single finger other than the thumb on the pressing block 58 and press down. The user can also place the thumb on the pressing block 58 for pressing training. At this time, it can drive the telescopic column 55 and the limit disk 57 to press down, thereby squeezing the spring 56 and deforming it, thus completing single-finger training. When multiple-finger pressing training is required, pull out the insertion rod 59 from the fixed block 11, then insert the insertion rod 59 into the four slots 581 in sequence, and then place the four fingers other than the thumb on the four pressing blocks 58 in sequence. At this time, the four fingers press down, thereby squeezing the four springs 56 and deforming them, thus completing simultaneous multiple-finger training. And the user only needs to rotate the worm 51 forward and backward. At this time, it can drive the worm wheel 52 and the threaded rod 53 to rotate forward and backward. By the forward and backward rotation of the threaded rod 53, it can drive the adjusting plate 54 to move up and down, thereby changing the deformation amount of the spring 56 and achieving the purpose of adjusting the training intensity.
