Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a bone repositioning and fixation device. Background Technology
[0002] Orthopedics is one of the most common departments in major hospitals, primarily studying the anatomy, physiology, and pathology of the musculoskeletal system. It utilizes medication, surgery, and physical therapy to maintain and develop the normal morphology and function of this system. With changes in the times and society, the spectrum of orthopedic injuries and diseases has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and polio have decreased significantly, while injuries from traffic accidents have increased significantly. This changing spectrum of orthopedic injuries and diseases necessitates that orthopedics keep pace with the times. During rehabilitation, because bone recovery is slow, it is necessary to avoid stress on the bones during the recovery period. Bone reduction and fixation devices can be used to immobilize injured bones.
[0003] However, existing bone repositioning and fixation devices have the following drawbacks:
[0004] (1) Existing bone reduction and fixation devices have a weak function in adjusting the angle of the patient's upper arm. When using them, traditional bone reduction and fixation devices are difficult to adjust the angle of the patient's arm according to the needs of different patients. Moreover, each patient's condition is different, which reduces the applicability of the device and reduces the treatment efficiency for different patients.
[0005] (2) Existing bone repositioning and fixation devices are less functional for patients with different forearm circumferences. When using them, the forearm circumferences of different patients are different, and traditional fixation devices can only fix a single circumference, making it difficult to adapt to other circumferences. This results in limitations of the device and reduced efficiency. Utility Model Content
[0006] The purpose of this invention is to provide a bone repositioning and fixation device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a bone repositioning and fixation device, comprising a base, a limiting groove formed at the top of the base, a first fixing plate slidably connected inside the limiting groove, a limiting block fixedly connected to one side of the first fixing plate, a first fixing rod fixedly connected inside the first fixing plate, an adjusting plate rotatably connected to the outer surface of the first fixing rod, a second fixing rod rotatably connected to the inner side wall of the adjusting plate, a second fixing plate fixedly connected to the outer surface of the second fixing rod, a lifting plate fixedly connected to the top of the second fixing plate, a connecting groove formed at the top of the base, a connecting slider slidably connected inside the connecting groove, a connecting block fixedly connected to the side of the connecting slider, a placement block fixedly connected to the top of the connecting slider, a limiting ring rotatably connected to one side of the placement block, and a fixing screw threaded inside the limiting ring.
[0008] Optionally, a limiting slot is provided inside the limiting slide groove, and the limiting block fits into the limiting slot. When the limiting block is inserted into the limiting slot, the limiting slot limits the limiting block, so that the limiting block is fixed inside the limiting slot.
[0009] Optionally, the connecting groove has a connecting slot inside, and the connecting block fits into the connecting slot. When the connecting block is inserted into the connecting slot, the connecting slot limits the position of the connecting block to prevent the position of the connecting block from shifting.
[0010] Optionally, the lifting plate is rotatably connected to a rotating rod inside, and a third fixing plate is fixedly connected to the outer surface of the rotating rod. When the angle of one side of the lifting plate is adjusted, the lifting plate will rotate on the surface of the rotating rod. At the same time, the rotating rod limits the lifting plate, and the third fixing plate supports and fixes the rotating rod.
[0011] Optionally, the top of the base is provided with a connecting groove, and the third fixing plate is connected to the connecting groove. The third fixing plate is fixed by the setting of the connecting groove, and the rotating rod is fixed by the setting of the third fixing plate.
[0012] Optionally, a circular slot is provided on one side of the third fixing plate, and the rotating rod is connected to the circular slot. The circular slot can limit and fix the rotating rod to prevent the position of the rotating rod from shifting.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This bone repositioning and fixation device, through the arrangement of a limiting slide groove, a first fixation plate, a limiting block, a first fixation rod, an adjusting plate, a second fixation rod, a second fixation plate, and a lifting plate, allows the patient to place their upper arm on the lifting plate during use. Medical personnel then insert the limiting block into the slot inside the limiting slide groove according to the patient's condition. Simultaneously, the limiting slide groove limits and fixes the first fixation plate. The adjusting plate adjusts its own angle, thereby driving the second fixation rod and the second fixation plate to move. The movement of the second fixation plate then causes the lifting plate to adjust its angle, thus improving the device's adjustment performance.
[0015] 2. This bone repositioning and fixation device, through the design of a connecting groove, connecting slider, connecting clip, placement block, limiting ring, and fixing screw, allows the patient to place their forearm on the placement block. Medical staff can then move the connecting slider according to the patient's forearm circumference. Simultaneously, the connecting groove limits the movement of the connecting slider. When the connecting slider reaches the appropriate position, the connecting clip engages with the slot inside the connecting groove, fixing the placement block in place. The limiting ring is then rotated to align with the surface of the patient's forearm, and the fixing screw is rotated to secure the patient's forearm to the surface of the placement block. This design improves the device's applicability, avoiding the limitations of traditional fixation devices that can only fix a single forearm circumference and cannot adapt to other forearm circumferences, thus reducing the device's efficiency.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a bone repositioning and fixation device, including a base 1, a limiting groove 2 on the top of the base 1, a first fixing plate 3 slidably connected inside the limiting groove 2, a limiting block 4 fixedly connected to one side of the first fixing plate 3, a first fixing rod 5 fixedly connected inside the first fixing plate 3, an adjusting plate 6 rotatably connected to the outer surface of the first fixing rod 5, a second fixing rod 7 rotatably connected to the inner side wall of the adjusting plate 6, a second fixing plate 8 fixedly connected to the outer surface of the second fixing rod 7, a lifting plate 9 fixedly connected to the top of the second fixing plate 8, a connecting groove 10 on the top of the base 1, a connecting slider 11 slidably connected inside the connecting groove 10, a connecting block 12 fixedly connected to the side of the connecting slider 11, a placement block 13 fixedly connected to the top of the connecting slider 11, a limiting ring 14 rotatably connected to one side of the placement block 13, and a screw inside the limiting ring 14. The patient places their upper arm on the lifting plate 9. Medical staff insert the limiting block 4 into the slot inside the limiting slide 2 according to the patient's condition. At the same time, the limiting slide 2 limits the first fixing plate 3, fixing the first fixing plate 3 and the first fixing plate 8. Meanwhile, the adjusting plate 6 adjusts its own angle, thereby driving the second fixing rod 7 and the second fixing plate 8 to move. The movement of the second fixing plate 8 drives the lifting plate 9 to adjust its angle. The patient places their forearm on the placement block 13. Medical staff can move the connecting slider 11 according to the patient's forearm circumference. At the same time, the connecting slide 10 limits the connecting slider 11. When the connecting slider 11 moves to the appropriate position, the connecting block 12 inserts into the slot inside the connecting slide 10, fixing the placement block 13. Then, the limiting ring 14 is rotated to fit the limiting ring 14 against the surface of the patient's forearm. Finally, the fixing screw 15 is rotated to fix the patient's forearm on the surface of the placement block 13.
[0023] The limiting slide 2 has a limiting slot 16 inside, and the limiting block 4 fits into the limiting slot 16. When the limiting block 4 is inserted into the limiting slot 16, the limiting slot 16 limits the limiting block 4, so that the limiting block 4 is fixed inside the limiting slot 16.
[0024] The connecting groove 10 has a connecting slot 17 inside. The connecting block 12 fits into the connecting slot 17. When the connecting block 12 is inserted into the connecting slot 17, the connecting slot 17 limits the connecting block 12 to prevent the position of the connecting block 12 from shifting.
[0025] The lifting plate 9 is rotatably connected to a rotating rod 18, and a third fixing plate 19 is fixedly connected to the outer surface of the rotating rod 18. When the angle of one side of the lifting plate 9 is adjusted, the lifting plate 9 will rotate on the surface of the rotating rod 18. At the same time, the rotating rod 18 limits the lifting plate 9, and the third fixing plate 19 supports and fixes the rotating rod 18.
[0026] The top of the base 1 is provided with a connecting groove, and the third fixing plate 19 is connected to the connecting groove. The third fixing plate 19 is fixed by the setting of the connecting groove, and the rotating rod 18 is fixed by the setting of the third fixing plate 19.

[0028] In this invention, the working steps of the device are as follows:
[0029] First step: The patient places their upper arm on the lifting plate 9. Medical staff insert the limiting block 4 into the slot inside the limiting slide 2 according to the patient's condition. At the same time, the limiting slide 2 limits the first fixing plate 3, fixing the first fixing plate 3 and the first fixing plate 3. Meanwhile, the adjusting plate 6 adjusts its own angle, thereby driving the second fixing rod 7 and the second fixing plate 8 to move. The movement of the second fixing plate 8 drives the lifting plate 9 to adjust its angle. The patient places their forearm on the placement block 13. Medical staff can move the connecting slider 11 according to the patient's forearm circumference. At the same time, the connecting slide 10 limits the connecting slider 11. When the connecting slider 11 moves to the appropriate position, the connecting block 12 inserts into the slot inside the connecting slide 10, fixing the placement block 13. Then, the limiting ring 14 is rotated to fit the limiting ring 14 against the surface of the patient's forearm. Finally, the fixing screw 15 is rotated to fix the patient's forearm on the surface of the placement block 13.
[0030] Second step: When the limiting block 4 is inserted into the limiting slot 16, the limiting slot 16 limits the limiting block 4, fixing the limiting block 4 inside the limiting slot 16. When the connecting block 12 is inserted into the connecting slot 17, the connecting slot 17 limits the connecting block 12 to prevent the position of the connecting block 12 from shifting. When the angle of one side of the lifting plate 9 is adjusted, the lifting plate 9 will rotate on the surface of the rotating rod 18. At the same time, the rotating rod 18 limits the lifting plate 9. The third fixing plate 19 supports and fixes the rotating rod 18.
[0031] The third step: The third fixing plate 19 is fixed by the setting of the connecting groove, and the rotating rod 18 is fixed by the setting of the third fixing plate 19.
