[0022] The technical solution of this utility model will be clearly and completely described below with reference to specific implementation schemes. However, those skilled in the art should understand that the implementation schemes described below are only for illustrating this utility model and should not be regarded as limiting the scope of this utility model. Based on the implementation schemes in this utility model, all other implementation schemes obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-2 As shown, according to an embodiment of the present invention, a tensioning structure 100 for a spinal traction device is provided, wherein the spinal traction device includes a cephalopelvic ring and a hip semicircular structure, and the tensioning structure 100 includes a plurality of first tensioning rods 10, a plurality of tensioning knobs 20 and a plurality of second tensioning rods 30.

[0024] The lower ends of multiple first tensioning rods 10 are connected to a semi-circular structure in the hip area, and the upper ends of the first tensioning rods 10 have threaded ends 11. A tensioning knob 20 is rotatably fitted onto the threaded ends 11 of the first tensioning rods 10. The upper ends of multiple second tensioning rods 30 are connected to a headband ring, and the lower ends of the second tensioning rods 30 are connected to the top of the tensioning knob 20.

[0025] In this invention, the top of the tension knob 20 is rotatably connected to the lower end of the second tension rod 30, meaning that rotating the tension knob 20 will not move the second tension rod 30. The bottom of the tension knob 20 is threadedly connected to the threaded end 11 on the first tension rod 10, meaning that rotating the tension knob 20 can cause the threaded end 11 to move forward or backward. Thus, the overall length of the first tension rod 10 and the second tension rod 30 can be adjusted stably and quickly, thereby adjusting the traction force of the head and pelvic ring.

[0026] In some embodiments, such as Figure 2 As shown, the tensioning knob 20 includes a main body 21. The upper end of the main body 21 is provided with a first through hole, and the lower end of the main body 21 is provided with a second through hole. An annular ring 22 is provided in the second through hole, and the annular ring 22 has internal threads. The lower end of the second tensioning rod 30 is provided with an abutment part 31. The second tensioning rod 30 passes through the second through hole into the main body 21 and exits through the first through hole. The diameter of the abutment part 31 is larger than the diameter of the first through hole. The annular ring 22 is fixedly connected to the main body 21 and is rotatably sleeved on the threaded end 11 of the first tensioning rod 10.

[0027] It is understandable that the lower end of the second tensioning rod 30 is provided with an abutment part 31, and the abutment part 31 is located entirely within the body 21 of the tensioning knob 20. This effectively improves the stability between the second tensioning rod 30 and the tensioning knob 20. At the same time, there is no connection between the first through hole and the second tensioning rod 30, which helps to reduce the friction between the second tensioning rod 30 and the tensioning knob 20.

[0028] Furthermore, a threaded hole can be provided on the bottom side of the main body 21, and a bolt can be installed in the threaded hole to fix the annular ring 22, so that the annular ring 22 is stably set in the second through hole. At the same time, the annular ring 22 can be quickly replaced after wear, extending the service life of the tensioning knob 20.

[0029] In some embodiments, such as Figure 2 As shown, the tension knob 20 also includes a pressure sensor 23, a display screen 24, and a power supply 25. The power supply 25 is located inside the main body 21, the display screen 24 is located on the side wall of the main body 21, and the pressure sensor 23 is located on the top of the main body 21. The abutment part 31 abuts against the pressure sensor 23, the pressure sensor 23 is connected to the display screen 24, and the power supply 25 is connected to the display screen 24.

[0030] Understandably, the pressure sensor 23 and the display screen 24 can display the magnitude of the traction force on the patient in real time, and can record feedback data between the magnitude of the traction force and the patient's pain and tolerance level. Throughout the treatment process, the traction force on the patient can be scientifically adjusted based on the feedback results.

[0031] In some embodiments, the pressure sensor 23 is annular, and the top of the contact portion 31 is a square plane or a circular plane.

[0032] In some embodiments, for every 360° rotation of the tension knob 20, the first tensioning rod 10 advances or retracts 1 mm within the tension knob 20.

[0033] In some embodiments, such as Figure 1 As shown, the tensioning structure 100 also includes a limiting nut 40, which is sleeved on the threaded end 11 of the first tensioning rod 10.

[0034] Understandably, the limit nut 40 helps prevent the tensioning structure 100 from being adjusted too quickly in one go, thus improving safety.

[0035] In some embodiments, the tensioning structure 100 further includes an auxiliary rotating device that can be engaged with the tensioning knob 20; preferably, the auxiliary rotating device is wrench-shaped.

[0036] According to an embodiment of the present invention, the spinal traction device includes a cephalopelvic ring, a hip semicircular structure, and a plurality of tensioning structures 100. The tensioning structures 100 are any of the tensioning structures described above, and the plurality of tensioning structures 100 are used to connect the cephalopelvic ring and the hip semicircular structure.
