Description

Technical Field

[0001] The invention relates to the field of dental medical treatment, in particular to a self-locking bracket unlocking tool. Background Art

[0002] In orthodontics, after the doctor bonds the orthodontic self-ligating brackets to the teeth, he begins to install the archwire, which is placed in the bracket groove. The deformation and repositioning ability of the archwire is then used to achieve malocclusion correction.

[0003] Existing, reference Figure 1 The self-ligating bracket includes a bracket body 101 and a locking cover 102. The bracket body 101 is provided with a groove for the archwire to be inserted into. The locking cover 102 is slidably mounted at a position corresponding to the groove of the bracket body 101. The outer wall of the bracket body 101 is also provided with a buckle groove 103 for buckling the locking cover 102 to open the locking cover 102.

[0004] Regarding the above-mentioned related technologies, doctors usually use ordinary probe tools to complete the process by pressing the locking cover. However, since the working end of the ordinary probe is very sharp, it is difficult to exert force when pressing the locking cover in the narrow oral space, which can easily injure the patient's gums and cause unnecessary pain. Summary of the invention

[0005] In order to improve the operating convenience of the lock cover switch and reduce harm to the patient, the present application provides a self-locking bracket unlocking tool.

[0006] The present application provides a self-locking bracket unlocking tool, which adopts the following technical solution:

[0007] A self-locking bracket unlocking tool comprises a handle, a first unlocking rod and a second unlocking rod, wherein the first unlocking rod and the second unlocking rod are respectively installed at two ends of the handle, the end of the first unlocking rod away from the handle is curved, and the second unlocking rod is straight; the end of the first unlocking rod away from the handle and the end of the second unlocking rod away from the handle are both adapted to the buckle groove of the self-locking bracket.

[0008] By adopting the above technical solution, when the lock cover needs to be opened, refer to Figure 2 The doctor holds the handle 1, inserts the end of the first unlocking rod 2 away from the handle 1 or the end of the second unlocking rod 3 away from the handle 1 into the buckle groove 103 of the self-locking bracket, and then tilts it upward with light force to open the lock cover 102; when the lock cover 102 needs to be closed, refer to Figure 3, directly place the end of the first unlocking rod 2 away from the handle 1 or the end of the second unlocking rod 3 away from the handle 1 on the top of the lock cover 102, and then press down lightly to close the lock cover 102; whether to use the first unlocking rod or the second unlocking rod depends on the doctor according to actual conditions and usage habits; therefore, the first unlocking rod and the second unlocking rod of the structure of the present application are both rod-shaped, and curved and straight unlocking rods are provided to improve applicability, thereby improving the convenience of operating the lock cover switch and reducing harm to patients.

[0009] Preferably, the first unlocking rod includes a connecting section and an elbow, one end of the connecting section is connected to the handle, and the elbow is connected to the other end of the connecting section, and an angle is formed between the elbow and the connecting section.

[0010] By adopting the above technical solution, when in use, the lock cover is opened and closed through the elbow, which is easy to operate and highly practical.

[0011] Preferably, the angle is 90°-110°.

[0012] By adopting the above technical solution, it will not be inconvenient to insert the elbow into the buckle groove of the self-locking bracket due to too small an angle, and it will not be inconvenient to exert force due to too large an angle.

[0013] Preferably, the connecting section is bent, and the bending part of the connecting section faces one side of the elbow.

[0014] By adopting the above technical solution, it is easier to exert force when tilting upward in the oral cavity with limited space, thereby improving the convenience of use.

[0015] Preferably, guide surfaces are provided on both sides of the first unlocking rod away from the end of the handle and on both sides of the second unlocking rod away from the end of the handle.

[0016] By adopting the above technical solution, it is smoother to insert the end of the first unlocking rod away from the handle or the end of the second unlocking rod away from the handle into the buckle groove of the self-locking bracket.

[0017] Preferably, both ends of the handle are provided with plug-in holes, and the first unlocking rod and the second unlocking rod are respectively inserted into the two plug-in holes by interference fit.

[0018] By adopting the above technical solution, not only is the installation convenient and stable, but also the first unlocking rod or the second unlocking rod can be directly pulled out when it is necessary to replace it, thereby improving practicality.

[0019] Preferably, the cross-sections of the handle, the first unlocking rod and the second unlocking rod are all circular.

[0020] By adopting the above technical solution, compared with a square shape, there is more space for better operation in the limited oral space and scratches on the oral cavity can be reduced.

[0021] Preferably, an arc chamfer is provided on the end of the first unlocking rod away from the handle and the end of the second unlocking rod away from the handle.

[0022] By adopting the above technical solution, the occurrence of screaming can be reduced, thereby reducing the risk of scratching the oral cavity and protecting the patient.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The first unlocking rod and the second unlocking rod of the structure of the present application are both rod-shaped, and the unlocking rods with curved shapes and straight shapes are provided to improve applicability, thereby improving the convenience of operating the lock cover switch and reducing harm to the patient;

[0025] 2. The angle between the elbow and the connecting section is not too small to make it difficult to insert the elbow into the buckle groove of the self-ligating bracket, nor is it too large to make it difficult to exert force;

[0026] 3. A guide surface is provided on the end of the first unlocking rod away from the handle or the end of the second unlocking rod away from the handle, so that it can be inserted into the buckle groove of the self-locking bracket more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
