[0002] In the process of applying the Begg technique, in order to protect the posterior teeth from mesial movement and intrude the upper and lower anterior teeth, a posterior-inclination bend (30°-40°) made of 0.016 special stainless steel round wire is usually required. As the anterior teeth are retracted by Class II traction, the maxillary arch wire will move distally, resulting in the posterior-inclination bend of the arch wire entering the buccal tube. Clinically, the arch wire is usually removed and the posterior-inclination bend is remade to continue retracting the anterior teeth. For example, the existing XBT buccal tube has the following problems: 1. The angle of the thin round wire tube is fixed and cannot be adjusted according to clinical needs; 2. The thin round wire tube can only accommodate round wires. Summary of the Invention

[0023] Embodiment 1:
[0024] As Figures 1 - 3 shown, a buccal tube includes a wire threading block 1, an angle adjustment structure, and a fixed connection structure. The angle adjustment structure includes a rotating block 21 and a threaded rod 22. The threaded rod 22 is threadedly connected to the wire threading block 1. The fixed connection structure is respectively connected to the rotating block 21 and the wire threading block 1. The orthodontic arch wire 5 passes through the fixed connection structure and the wire threading block 1.
[0025] A wire threading cavity (not shown in the figure) is provided inside the wire threading block 1. Both ends of the wire threading cavity penetrate through the wire threading block 1. The orthodontic arch wire 5 passes through the wire threading cavity. The wire threading block 1 is also provided with a first wire threading hole 11 and a second wire threading hole 12. The first wire threading hole 11 and the second wire threading hole 12 are respectively communicated with the wire threading cavity. According to Figure 1 the visual angle, the first wire threading hole 11 is located on the front end face of the wire threading block 1, and the second wire threading hole 12 is located on the right end face of the wire threading block 1. In this embodiment, the first wire threading hole 11 serves as the inlet of the orthodontic arch wire 5, and the second wire threading hole 12 serves as the outlet of the orthodontic arch wire 5. The first wire threading hole 11, the wire threading cavity, and the second wire threading hole 12 form a wire threading channel for the orthodontic arch wire 5, that is, the orthodontic arch wire 5 penetrates into from the first wire threading hole 11, passes through the wire threading cavity, and exits from the second wire threading hole 12.
[0026] The wire threading block 1 is also provided with a fixed groove 13. The fixed groove 13 is communicated with the wire threading cavity. According to Figure 1 the visual angle, the fixed groove 13 is located on the upper end face of the wire threading block 1.
[0027] In other embodiments, when it is not necessary to adjust the magnitude of the tip-back bend or for other needs, the orthodontic arch wire 5 can also pass through other inlets or outlets. For example, a wire threading hole can be provided on the left end face of the wire threading block 1 as the inlet, and the orthodontic arch wire 5 enters from this inlet and exits from the second wire threading hole 12. This embodiment does not limit this.
[0028] The angle adjustment structure is arranged on the front end face of the wire threading block 1. The angle adjustment structure and the first wire threading hole 11 are on the same side of the wire threading block 1. The angle adjustment structure includes a rotating block 21 and a threaded rod 22. The wire threading block 1 is provided with a threaded hole (not shown in the figure). One end of the threaded rod 22 is arranged in the threaded hole and is threadedly connected to the threaded hole. The other end of the threaded rod 22 is fixedly connected to the rotating block 21. When the rotating block 21 is rotated, the threaded rod 22 rotates synchronously, and thus the distance between the rotating block 21 and the front end face of the wire threading block 1 can be adjusted.
[0029] The angle adjustment structure further includes a resisting block 23. The resisting block 23 is fixedly arranged on the front end face of the wire threading block 1. The threaded rod 22 is first threadedly connected to the resisting block 23 and then penetrates through the resisting block 23 to be threadedly connected to the wire threading block 1.
[0030] The fixed connection structure includes a fixing frame 31 and a connecting block 32. The fixing frame 31 is fixedly connected to the wire threading block 1. The connecting block 32 is slidably connected to the fixing frame 31, and the connecting block 32 is rotatably connected to the rotating block 21.
[0031] Specifically, the rotational connection between the connecting block 32 and the rotating block 21 can be realized by an existing bearing. When the rotating block 21 rotates, the connecting block 32 remains non-rotating. The sliding connection between the connecting block 32 and the fixing frame 31 can be realized by a conventional slide rail and slider. Combining the sliding connection between the connecting block 32 and the fixing frame 31 and the rotational connection between the connecting block 32 and the rotating block 21, when the rotating block 21 rotates, the connecting block 32 follows the rotating block 21 to slide along the fixing frame 31, so that the distance between the connecting block 32 and the front end face of the wire threading block 1 changes.
[0032] The connecting block 32 is provided with a through hole (not shown in the figure) penetrating left and right. The orthodontic arch wire 5 first passes through the through hole and then through the wire threading channel. The size of the through hole is larger than the size of the orthodontic arch wire 5. Both the circular orthodontic arch wire 5 and the square orthodontic arch wire 5 can pass through the through hole, improving the adaptability range of the buccal tube for the orthodontic arch wire 5.
[0033] The orthodontic arch wire 5 includes a horizontal end and an inclined end. The horizontal end passes through the through hole, and the inclined end passes through the wire threading channel. During the rotation of the rotating block 21, the horizontal end always remains horizontal. As the distance between the connecting block 32 and the wire threading block 1 changes, the angle between the inclined end and the wire threading block 1 changes, so that the size of the posterior bend can be adjusted as needed.
[0034] To avoid the problem that the orthodontic arch wire 5 shakes during use due to the gap between the through hole and the orthodontic arch wire 5, the fixed connection structure is further provided with a tightening screw 33. The connecting block 32 is provided with a tightening hole (not shown in the figure). The tightening screw 33 passes through the tightening hole and is threadedly connected to the tightening hole. The tightening hole is communicated with the through hole. When it is necessary to fix the orthodontic arch wire 5, rotate the tightening screw 33 to tighten the orthodontic arch wire 5 located inside the through hole.
[0035] The buccal tube is further provided with a fitting plate 4, and the fitting plate 4 is fixedly connected to the wire threading block 1.
[0036] The buccal tube is further provided with a hook 6, and the hook 6 is fixedly connected to the wire threading block 1. The hook 6 is located at the rear end face of the wire threading block 1, and the hook 6 is used to connect a belt to correct the angle of the teeth in the vertical direction.
[0037] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
