Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tooth correction, in particular to a traction hook for orthodontics. BACKGROUND

[0002] With the development of orthodontic treatment technology and the enhancement of people's awareness of oral health, orthodontic treatment is becoming more and more common, and more and more patients expect to improve the dental deformity through orthodontic treatment. In addition to aligning teeth, improving the appearance of the side becomes another big demand for patients to come to the clinic. Orthodontic treatment not only can correct teeth, but also can improve the appearance of the face by coordinating the relationship between teeth and jaw bones to achieve the purpose of beauty and health. In orthodontic treatment, some auxiliary tools are often needed to achieve the purpose of treatment, and the traction hook is used frequently, especially in the case of tooth extraction or fine adjustment of the occlusal relationship. The traction hook is used in cooperation with the rubber band to correct the teeth.

[0003] The installation slot of the existing traction hook mounting seat is square, has edges and corners, and has poor fit with the cylindrical installation base, is easy to loosen, and is suitable for the cylindrical arch wire of the active appliance. The hook direction of the traction hook cannot be adjusted, and cannot be applied to more correction devices, such as the rear support arm of the dental arch expander, which needs an L-shaped hook to cooperate with the hook on the inner side of the front end of the molar ring to push the molar backward. Therefore, there is an urgent need for a traction hook that can be closely matched with the cylindrical installation base and has an adjustable hook direction to solve the problems in the prior art. SUMMARY

[0004] The purpose of the present application is to provide a traction hook for orthodontics to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose of the application, the technical scheme adopted by the present application is as follows:

[0006] A traction hook for orthodontics, comprising: a C-shaped mounting seat, a telescopic rod fixed on the C-shaped mounting seat, and a anti-disengagement head threadedly connected to the telescopic part of the telescopic rod.

[0007] A first threaded hole is formed in the end face of the telescopic part, and a second threaded hole is formed in the side wall of the telescopic part, and the anti-disengagement head can be threadedly connected with the first threaded hole or the second threaded hole.

[0008] An anti-slip pattern is arranged on the inner wall of the C-shaped mounting seat.

[0009] Further, a limiting groove is formed in the side wall of the telescopic part, and the limiting groove is located between the second threaded hole and the first threaded hole.

[0010] Further, the telescopic rod can be locked at any position within the telescopic range.

[0011] The traction hook for orthodontics has the following advantages compared with the prior art.

[0012] 1. The device can be well fitted to the cylindrical mounting base through the C-shaped mounting seat, and the anti-skid design further improves the installation stability of the traction hook, preventing horizontal sliding or angle inclination of the traction hook.

[0013] 2. The device can change the direction of the anti-disengagement head by opening the first threaded hole in the end face of the telescopic part and the second threaded hole in the side wall of the telescopic part, thereby adapting to the traction requirements of more correction devices. BRIEF DESCRIPTION OF DRAWINGS

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings needed to be used in the embodiment or prior art description. Obviously, the drawings in the following description are only embodiments of the present application, and those skilled in the art can obtain other drawings according to the provided drawings without creative labor.

[0017] In the figure: 1-C-shaped mounting seat, 2-telescopic rod, 3-anti-disengagement head, 4-first threaded hole, 5-second threaded hole, 6-limiting groove. DETAILED DESCRIPTION

[0018] The technical solutions of the present application will be further described below in combination with the drawings and embodiments:

[0019] Reference Figs. 1-2 As shown in the figure, the present application provides a traction hook for orthodontics, which comprises: a C-shaped mounting seat 1, a telescopic rod 2 fixed on the C-shaped mounting seat 1, and an anti-disengagement head 3 threadedly connected to the telescopic part of the telescopic rod. The inner wall of the C-shaped mounting seat 1 is provided with anti-skid lines. The C-shaped mounting seat 1 can be well fitted to the cylindrical mounting base, and the design of the anti-skid lines further improves the installation stability of the traction hook, preventing horizontal sliding or angle inclination of the traction hook.

[0020] As a preferred embodiment, the end face of the telescopic part is provided with a first threaded hole 4, the side wall of the telescopic part is provided with a second threaded hole 5, and the anti-disengagement head 3 can be threadedly connected with the first threaded hole 4 or the second threaded hole 5. By changing the installation position of the anti-disengagement head 3, the direction of the hook can be changed, thereby adapting to the traction requirements of more correction devices.

[0021] As a preferred embodiment, a limiting groove 6 is formed on the side wall of the telescopic part, and the limiting groove 6 is located between the second threaded hole 5 and the first threaded hole 4. When the anti-disengagement head 3 is installed in the first threaded hole 4, the limiting groove 6 is used to limit the sliding displacement of the rubber band or the rubber chain on the telescopic part, so as to ensure the quality of traction.
