Technical Field

[0001] This invention relates to the field of physiotherapy devices for lumbar spondylolisthesis reduction, and in particular to an assembled lumbar spondylolisthesis reduction device that facilitates physiotherapy reduction. Background Technology

[0002] Lumbar spondylolisthesis is a condition caused by congenital malformation, trauma, strain, or other reasons that lead to abnormal bony connections between adjacent vertebrae, resulting in partial or complete slippage between the upper and lower vertebrae. Symptoms include lumbosacral pain, sciatic nerve involvement, and intermittent claudication. Patients with lumbar spondylolisthesis need to seek medical attention promptly for repositioning and physical therapy.

[0003] A search revealed that invention patent CN109498077B discloses a lumbar spondylolisthesis reduction device, which includes a handle and a support head. The handle and support head form an angle of 90° to 145°. The handle includes a first handle and a second handle, with the first handle hinged to the second handle. The front ends of the first and second handles are respectively provided with a first support head and a second support head. The first support head includes a connecting rod and a lifting rod. The rear part of the lifting rod is sleeved within the connecting rod. The front ends of both the lifting rod and the second support head are plate-shaped, and their outer surfaces are provided with triangular teeth. This solution can both open and lift the vertebral body.

[0028] The transmission structure inside the support frame 1 and the associated frame 2 can be manually rotated to adjust the lifting wheel 32. By utilizing the matching relationship between the lifting screw 11 and the lifting bearing block 26, the bearing back plate 7 can be driven to perform stable and continuous lifting and adjusting operations within the priority distance of the lifting and adjusting slot 6. The lifting and adjusting main gear 33 drives the transmission gear 34 to rotate through the associated meshing structure of the transmission chain 35, thereby achieving the effect of synchronous rotation of the double-end lifting and adjusting screw 11. This makes the device more widely applicable and can be used in physiotherapy operations for patients of various body types, enriching the overall functionality.

[0029] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0030] The telescopic structure between the push rod 46 and the extension rod 47 allows the device to adjust the overall reduction force by changing the length between the push rod 46 and the extension rod 47 when performing lumbar spondylolisthesis reduction using a lever structure, thereby achieving a more efficient reduction effect. Furthermore, the addition of the operating ball head 55 makes the reduction operation more convenient for medical staff, helping to reduce the difficulty of using the device and improve its overall ease of use.

[0031] Working principle: When using this device to perform reduction physiotherapy on patients with lumbar spondylolisthesis, the assembly of the device is completed first. Without the tightening pressure of the cap fastening bolts 24, the limiting cap 9 will remain open at the upper end of the support frame 1 due to the elastic properties of the elastic torsion spring bracket 10. The fully assembled load-bearing backplate 7 is then stably secured to the upper end of the support frame 1 using the dimensional compatibility between the lifting load-bearing block 26 and the lifting adjustment slot 6. The lifting adjustment screw hole 36 and the lifting adjustment screw 11 correspond to each other, allowing for a smooth downward press on the load-bearing backplate 7. The lifting adjustment wheel 32 is then rotated in a fixed direction, causing the lifting adjustment shaft 13 and the lifting adjustment main gear 33 to rotate in the same direction. The transmission chain 35 and the lifting adjustment... The meshing structure between the main gear 33 and the transmission gear 34 drives the double-ended lifting adjustment screw 11 to rotate in the rotating base 12, causing the entire supporting back plate 7 to move downward to a suitable position. Then, the upper limit cover 9 is placed on top, and the matching threaded connection between the cover fastening bolt 24 and the cover fastening inner thread sleeve 23 is used to fasten the upper limit cover 9 on the support frame 1. This ensures that the lifting adjustment screw 11 can rotate between the rotating base 12 and the rotating top seat 22, and also effectively limits the displacement distance of the supporting back plate 7. The assembled reset device is then attached to the designated position on the back of the patient to be reset with the soft pad 3, and the first lateral protective pad 4 and the second lateral protective pad 5 are positioned with both ends facing the patient. The front is tightened, and the thickened soft pad 15 provides support and protection for the patient's waist, enhancing the overall experience during the reduction process. Pulling the elastic adaptable strap 17 then secures the alignment fastening buckle 16 within the alignment sleeve 19, preventing displacement or slippage of the reduction device during use. The fastening ropes 18 at both ends can also be tightened for double-limiting protection. Based on the lumbar spine position required for reduction therapy, the height of the support backplate 7 is adjusted by rotating the lifting adjustment wheel 32. Then, the displacement adjustment wheel 38 drives the displacement adjustment screw 39 to fine-tune the parallel position of the displacement support block 40 within the displacement adjustment groove 27. Once in the appropriate position, the medical staff operating the device grasps the operating ball head 55 and pulls the manual lever 52 backward. Utilizing the lever principle, the manual lever 52 pushes the push rod 46 forward, applying pressure to the physiotherapy pad 28 via the push block 49. This achieves a physiotherapy effect by repositioning the slipped lumbar vertebrae. Alternatively, an external inflation device can be connected to the inflation interface 30 to inflate the inflatable traction pad 29, providing a better repositioning and traction effect. After use, the limiting cover 9 can be opened to remove the entire supporting backplate 7 from the support frame 1, reducing wear and tear from long-term use and extending the overall lifespan. This device can be applied to physiotherapy patients of various body types and has extremely broad application prospects.Simultaneously, the threaded connection structure of the push block 49 allows the pusher of the resetting device to be appropriately replaced according to specific usage requirements. During use, the resetting device can also have its support backplate 7 replaced according to the patient's desired resetting method. The replacement assembly backplate 58 and its entire assembly are stably mounted on the support frame 1 using the lifting support block 26. Similarly, the position of the replacement assembly backplate 58 within the support frame 1 can be appropriately adjusted according to the resetting position before wearing the device. It is worth noting that before fully wearing and securing the device, the position of the suction plates 61 in the two cupping sleeves 60 needs to be appropriately adjusted. One suction cup 61 is located at the very end of the cupping sleeve 60, while the other suction cup 61 is located at the very top. The cupping sleeve 60 is fully fitted to the specific location on the patient requiring physiotherapy repositioning. Utilizing the threaded connection between the negative pressure adjusting wheel 64 and the negative pressure adjusting screw 66, rotating the negative pressure adjusting screw 66 causes the suction cup 61 to move upwards inside the cupping sleeve 60, achieving a negative pressure suction effect on one end of the repositioning position. Then, rotating the other end of the negative pressure adjusting wheel 64 moves the suction cup 61 downwards inside the cupping sleeve 60, applying pressure to achieve the repositioning effect.
