Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable orthodontic traction hook. Background Art
[0002] With the development of orthodontic treatment technology and the enhancement of people's awareness of oral health care, orthodontic treatment is becoming more and more common, and more patients expect to improve their maxillofacial deformities through orthodontic treatment. In addition to aligning teeth, improving profile has become another major demand of patients when they come to the doctor. Orthodontic treatment can not only correct teeth, but also improve the aesthetics of the face by coordinating the relationship between teeth and jaws to achieve the purpose of beauty and health. In orthodontic treatment, some auxiliary tools are often needed to achieve the purpose of treatment. Orthodontic traction hooks are used frequently, especially in cases of tooth extraction or fine adjustment of the occlusal relationship. The traction hook is used in conjunction with the rubber band to pull and correct the teeth.
[0003] Currently, the commonly used traction hooks have three main lengths: low, medium and high. The size and length of the traction hook should be selected according to needs before use. After selection, it is fixed on the orthodontic arch wire until the end of use. The length cannot be adjusted during use. In some cases, a low traction hook is used to tilt and move the front teeth due to the large lip inclination of the front teeth at the beginning of treatment. After a period of treatment, the angle of the front teeth is normal and the way of tooth movement needs to be changed. The original traction hook can only be removed or even the arch wire can be replaced, and the appropriate type of traction hook can be selected to re-fix it, which increases clinical operation time and use cost.

[0013] As a further improvement and optimization of this solution, the bottom side wall of the middle section and the top side wall of the first section are both laterally provided with mounting grooves, and the two locking balls are respectively arranged at the groove openings of the two mounting grooves. Each mounting groove has a spring, one end of the spring is connected to the bottom of the mounting groove, and the other end is connected to the locking ball.
[0014] As a further improvement and optimization of the present solution, the cross-sections of the first section, the middle section, and the tail section are all rectangular structures.
[0015] As a further improvement and optimization of the present solution, the bottom inner wall of the clamping groove is inclined, and the angle formed between the side wall of the clamping groove and the bottom inner wall of the clamping groove is an obtuse angle.
[0016] As a further improvement and optimization of this solution, both sides of the notch of the clamping groove are provided with limit blocks.
[0017] As a further improvement and optimization of the present solution, the crossbar is a rectangular structure with rounded corners on its edges.
