The second support rod 42 is used to support and connect the adjacent first support rod 41, and the first support rod 41 and the second support rod 42 are connected by a second adjustment connecting block 82.

[0038] Specifically, the first support rod 41 and the second support rod 42 are both round rod structures. The second support rod 42 is arranged perpendicular to the first support rod 41. The first support rod 41 is arranged at the end of the electric adjustment push rod 51, and the first support rod 41 and the electric adjustment push rod 51 are arranged coaxially, thereby ensuring the consistency of traction support of the connecting rod assembly 3; the second support rod 42 is fixed on the first support rod 41, and the two adjacent first support rods 41 are fixedly supported by the second support rod 42 to prevent the support rods from moving.

[0039] In this embodiment, there are four first support rods 41, which are respectively arranged at the ends of four electric adjustment push rods 51, and there are two second support rods 42, which are respectively used to connect and fix the two first support rods 41 located on the left and right sides.

The support rod and the locking block have an interference fit, so that not only the support rod and the mounting slot of the locking block form a snap-fit ​​structure, but the mounting portion 824 and the support rod adopt a detachable snap-fit ​​connection method, which is not only simple to connect, but also ensures the stability of the installation, realizes firm and reliable locking, and avoids falling off during use.

[0041] The mounting hole 825 is a through hole structure axially arranged through the locking block. The fastening screw 823 passes through the mounting holes of the two locking blocks in turn, and then the two locking blocks are connected. By adjusting the fastening screw 823, the mounting position of the locking block can be adjusted, thereby adjusting the installation direction of the connecting rod assembly.

[0042] Furthermore, in the present embodiment, when the second adjustment connecting block 82 is in use, since the first support rod 41 and the second support rod 42 are cross-arranged, the mounting slots on the first locking block 821 and the second locking block 822 correspond to the support rod arrangement; and the front end portion of the fastening screw 823 is provided with a thread, and the mounting hole of the second locking block is provided with a threaded hole structure that is compatible with the fastening screw thread, so that the fastening screw 823 can be threadedly connected with the mounting hole 825 of the first locking block 821 after passing through the mounting hole 825 of the first locking block 821, thereby increasing the fastening effect of the fastening screw 823.

[0043] Furthermore, as a preferred embodiment of the utility model, a buffer portion 826 is provided on the first locking block 821 and the second locking block 822. The buffer portion 826 is a buffer hole structure provided on the locking block. The buffer hole structure is provided through and along the axial direction of the locking block. The buffer portion can enable the locking block to have a buffer space when the support rod is connected, thereby increasing the reliability of the connection.

[0044] Furthermore, in the present embodiment, a threaded bone needle 9 is connected to the second support rod 42, and the threaded bone needle 9 is vertically connected to the second support rod 42 through a third adjusting connecting block 83, and the threaded bone needle 9 is cross-arranged with the first support rod 41, and the threaded bone needle 9 is radially arranged along the traction frame; there are two threaded bone needles 9 connected to the support rod, which are respectively arranged on two second support rods 42 on both sides. When in use, the threaded bone needle 9 can be driven into the patient's ilium, and by adjusting the third adjusting connecting block 83, the installation position and depth length of the threaded bone needle 9 can be adjusted as needed.

[0045] like Figure 4 As shown, the pelvic end fixing part 2 is arranged at the end of the first support rod 41, and the pelvic end fixing part 2 is connected to the first support rod 41 through the first adjusting connecting block 81. The pelvic end fixing part 2 includes two relatively arranged bent support rods 21, and the bent support rod 21 is a "L-shaped" bent rod-shaped structure. The two relatively arranged bent support rods 21 form an arc-shaped covering structure. The upper end of each bent support rod 21 is connected to the end of the upper first support rod 41 through the first adjusting connecting block 81, and the lower end of each bent support rod 21 is connected to the end of the lower first support rod 41 on the other side through the first adjusting connecting block 81. The two bent support rods 21 form an arc-shaped spinal traction support structure, so that the two bent support rods 21 cooperate to achieve traction support for the pelvic end, so that the head fixing part 1, the pelvic end fixing part 2 and the connecting rod assembly 3 form a traction range covering the patient's head to the chest, abdomen and pelvis.

[0046] Furthermore, in the present embodiment, the first support rod 41, the second support rod 42 and the bent support rod 21 are all made of carbon fiber. Since the support rod made of carbon fiber has no development during under-arm X-ray photography and does not affect the photographic effect, there is no need to remove the connecting parts, and the side bending angle can be adjusted under X-ray, which is convenient and quick to use.

[0047] In this embodiment, the adjusting screw rod 61 and each adjusting connecting block are made of stainless steel, and the structure is firm and stable.

[0048] In this embodiment, the first adjustment connecting block 81 and the third adjustment connecting block 83 are both composed of two locking blocks and fastening screws. The difference from the setting of the second adjustment connecting block 82 is that due to the different sizes required for the connecting support rods, the specific sizes and models of the matching adjustment connecting blocks are also different.

[0049] Furthermore, as a preferred embodiment of the present invention, the specific specifications and the number of the connecting rod assembly 3 provided between the head fixing member 1 and the pelvic end fixing member 2 can be adjusted according to the use requirements and are not limited to a fixed number.

[0051] The utility model has a simple structure and is easy to operate. The doctor can quickly complete the pre-operative preparations. The traction force of the traction frame can increase the patient's spinal gap, thereby reducing the pressure on the nerve roots, relieving pain and muscle spasms. The traction can also stretch the curved spine, thereby correcting the spinal deformity. The utility model achieves traction on the patient's spine through the cooperation of the head fixing part, the pelvic end fixing part and the connecting rod assembly. The traction frame can reduce the spinal pressure and promote the self-repair of the spine. And through the setting of the automatic adjustment push rod, the height of the connecting rod assembly can be automatically adjusted through intelligent control, so as to quickly adjust the support length, which can improve the efficiency of the operation and save the operation time. Moreover, the patient can also adjust the height appropriately by himself during the spinal correction and recovery process to ensure the spinal traction effect. The traction frame can help patients to perform self-treatment at home, reduce the number of medical visits, and reduce the burden on the family.

[0052] Moreover, the traction frame of the utility model can realize controllable adjustment of the installation height and angle. Under the adjustment action of the electric adjustment push rod, the traction frame can be adjusted according to the patient's height and body shape, and the traction frame can realize electric height adjustment through intelligent control, thereby ensuring the comfort during the operation and improving the efficiency and quality of the operation; and under the action of different installation adjustment holes of the head frame and various adjustment connecting blocks, the traction angle of the traction frame can be adjusted according to the needs of the operation to achieve the best orthopedic effect.
