[0002] Distal radius fractures are a common type of upper limb fracture, usually treated with manual reduction combined with plaster casts or splints. According to orthopedic rehabilitation theory, patients with radius fractures should begin functional exercises as early as possible, based on the healing progress, to avoid complications such as joint stiffness and muscle adhesions. However, traditional fixation methods like plaster casts and splints are not convenient for patients to perform rehabilitation exercises. Furthermore, portable equipment that provides muscle strengthening exercises after fracture healing is relatively scarce.

[0005] In the aforementioned prior art, the resistance of wrist training cannot be adjusted when the patient is performing wrist training. Therefore, during the wrist rehabilitation process, the resistance of movement cannot be flexibly adjusted according to the patient's rehabilitation status.

[0006] To address the aforementioned problems, this utility model proposes an intelligent rehabilitation brace for fractures. Utility Model Content

[0007] To address the problems existing in the background technology, this utility model proposes an intelligent rehabilitation brace for fractures.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A smart rehabilitation brace for fractures includes an upper shell and a lower shell, both of which are configured as semi-conical shells. The upper shell and the lower shell are fastened together to form a frustum cone shape. The upper shell and the lower shell are symmetrically provided with first connecting holes at positions close to each other. The brace is characterized by including connecting plates, which are located at the front ends of the upper shell and the lower shell. There are two connecting plates, both of which are semi-circular. The two connecting plates are fastened together to form a cylindrical shape. The two connecting plates are provided with second connecting holes at positions close to each other.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: Example 1 A smart rehabilitation brace for fractures. It includes an upper shell 1 and a lower shell 2, both of which are semi-conical shells. The upper shell 1 and lower shell 2 are fastened together to form a frustum-shaped cone. First connecting holes 3 are symmetrically provided at positions close to each other on the upper shell 1 and lower shell 2.

[0020] When in use, fasten the upper shell 1 and the lower shell 2 to both sides of the arm, and use bandages or Velcro to pass through the first connecting holes 3 on the upper shell 1 and the lower shell 2 to fix them in place.

[0021] The upper shell 1 and the lower shell 2 are provided with connecting plates 17 at their front ends. There are two connecting plates 17, both semi-circular in shape. The two connecting plates 17 are fastened together to form a cylindrical shape. A second connecting hole 18 is provided at the close proximity of the fastened positions of the two connecting plates 17. A glove is placed between the two connecting plates 17. The glove is prior art and is not shown in the figure.

[0022] Put the patient's hand into the glove between the two connecting plates 17, and use straps or Velcro to pass through the second connecting hole 18 to secure the two connecting plates 17 to the patient's hand.

[0023] Furthermore, resistance units are provided between the connecting plate 17 and the upper shell 1, and between the connecting plate 17 and the lower shell 2. When the connecting plate 17 moves relative to the upper shell 1, the resistance units apply resistance to the connecting plate 17.

[0024] Here, only the resistance unit between the upper shell 1 and the connecting plate 17 will be described in detail. As for the resistance unit between the lower shell 2 and the connecting plate 17, it is sufficient to simply install the structure that is mounted on the upper shell 1 on the lower shell 2.

[0025] Specifically, the resistance unit includes: control box 4, connecting post 20 and elastic rope 14.

[0026] The control box 4 is fixedly mounted on the upper shell 1. An adjustment unit is provided inside the control box 4, and two pull ropes 13 are provided on the adjustment unit.

[0027] A mounting base 19 is fixedly installed on the connecting plate 17. Two connecting posts 20 are provided and fixedly connected to the mounting base 19.

[0028] Two elastic ropes 14 are provided, each corresponding to a connecting post 20. One end of each elastic rope 14 is fixed to the corresponding connecting post 20. The other end of each elastic rope 14 is fixedly connected to the corresponding pull rope 13.

[0029] Furthermore, a second rotating shaft 15 is fixedly installed on the upper shell 1. The axis of the second rotating shaft 15 is perpendicular to the axis of the upper shell 1. The second rotating shaft 15 is located inside the control box 4, and two guide wheels 16 are installed on the second rotating shaft 15. The pull rope 13 passes around the guide wheels 16 and is connected to the elastic rope 14.

[0030] After the patient puts on the protective gear, the patient's wrist rotation will cause the connecting plate 17 to rotate as well. As the connecting plate 17 rotates, the elastic rope 14 will apply resistance. The adjustment unit adjusts the preset elastic force of the elastic rope 14, thereby applying different resistances to the connecting plate 17.

[0031] The adjustment unit includes a lead screw 6 and a slider 8.

[0032] The axis of the lead screw 6 is perpendicular to the axis of the upper shell 1, and the lead screw 6 is rotatably connected to the control box 4. A first rotating shaft 11 is rotatably mounted on the side wall of the control box 4. A worm gear 10 is fixedly mounted on the first rotating shaft 11. A worm wheel 9 that mates with the worm gear 10 is fixedly mounted on one end of the lead screw 6. The outer end of the first rotating shaft 11 passes through the control box 4 and a knob 12 is fixedly mounted thereon.

[0033] The upper surface of the control box 4 is provided with a slide rail 7 parallel to the lead screw 6. Two sliders 8 are threadedly connected to the lead screw 6. The sliders 8 are slidably connected to the slide rail 7. The screws 6 and the two sliders 8 are threaded in opposite directions, and the end of the pull rope 13 away from the elastic rope 14 is fixed to the two sliders 8 respectively.

[0034] Rotating knob 12 drives worm gear 9 via worm 10, which in turn drives lead screw 6. When lead screw 6 rotates in different directions, it causes slider 8 to move towards or away from each other.

[0035] When the two sliders 8 move in opposite directions, the pull rope 13 will further tighten the elastic rope 14, thereby increasing the preset elastic force of the elastic rope 14. This increases the resistance when the connecting plate 17 moves.

[0036] When the two sliders 8 move towards each other, the pull rope 13 loosens the elastic rope 14, thereby reducing the preset elastic force of the elastic rope 14. This reduces the resistance when the connecting plate 17 moves.

[0037] The specific usage method of this application is as follows: In use, the upper shell 1 and lower shell 2 are fastened onto the patient's forearm, and bandages or Velcro are threaded through the first connecting holes 3 on the upper shell 1 and lower shell 2 to secure them. At the same time, the patient's hand is put into the glove between the two connecting plates 17, and the two connecting plates 17 are secured to the patient's hand using straps or Velcro threaded through the second connecting holes 18.

[0038] The patient can raise and lower their hand to move the joint between their hand and forearm. At this time, the hand needs to overcome the tension of the elastic rope 14 on the corresponding side, thereby increasing the resistance of the patient's movement and achieving the purpose of strength recovery.

[0039] As the exercise progresses, the patient's strength recovers to some extent. The tension of the elastic rope 14 can be adjusted according to the patient's recovery progress, thereby increasing the resistance to the patient's hand movements and further improving the recovery speed of the patient's hand strength. Furthermore, since the connecting plate 17 is not connected to the upper shell 1 and the lower shell 2, the patient's hand can perform recovery training in any direction.

[0040] The process of adjusting the tension of the elastic rope 14 is as follows: Rotate the knob 12, causing the first rotating shaft 11 to drive the worm gear 10 to rotate, which in turn drives the lead screw 6 to rotate through the worm wheel 9, causing the two sliders 8 to slide in opposite directions under the limit of the slide rail 7. Pull the pull rope 13 into the control box 4, so that the pull rope 13, guided by the guide wheel 16, pulls the elastic rope 14 to extend. This increases the tension of the elastic rope 14, increases the resistance of the patient's hand movement, enhances the patient's strength recovery, and can also be quickly adjusted according to different patients, improving the applicability of the device.

[0041] In this application, the elastic rope 14 on the upper shell 1 can also be removed, and the front end of the pull rope 13 can be directly fixed to the connecting post 20, while the elastic rope 14 on the lower shell 2 is retained. At this time, the knob 12 on the upper shell 1 can be rotated forward and backward to tighten or release the pull rope 13, thereby allowing the pull rope 13 to pull the patient's hand to perform passive training with large up and down swings. This mode is suitable for patients with very poor hand strength.

[0042] Example 2 This embodiment is a further improvement based on Embodiment 1.

[0043] Specifically, it is a smart rehabilitation brace for fractures. It includes a mounting base 19, which is fixedly mounted on a connecting plate 17. A battery and control circuit are fixedly installed inside the control box 4. A distance sensor is fixedly installed between the two sliders 8. A motion sensor 21 is fixedly installed on the mounting base 19. A display screen 5 is fixedly installed on the top of the control box 4. The control circuit is electrically connected to the battery, distance sensor, motion sensor 21, and display screen 5 via wires.

[0044] In this embodiment, by adding a distance sensor and a display screen 5, the amplitude of the patient's movement and the magnitude of the resistance during activity can be clearly tracked and fed back. This facilitates patient recording and adjustment.

[0045] The distance sensor detects the distance between the two sliders 8, allowing the control circuit to determine the current tension of the elastic rope 14, i.e., the resistance to the patient's hand movements, and display it on the screen 5 for the patient to adjust. The motion sensor 21 detects the amplitude and number of movements of the patient's hand, thus reminding the patient to perform reasonable and efficient exercises to help improve the speed of recovery.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
