Description

Technical Field

[0001] This utility model belongs to the field of assistive tool technology and relates to a drilling device for invisible orthodontic appliances. Background Technology

[0002] Invisible aligners are transparent, removable, and customized orthodontic tools. Their core function is to use gentle and continuous force to gradually move crowded, sparse, protruding, or reverse-occlusal teeth into the correct position, ultimately achieving straight teeth. They also improve the bite relationship between the upper and lower teeth, reduce tooth wear, improve chewing efficiency, and prevent temporomandibular joint discomfort caused by occlusion problems. Their biggest advantage is their transparent appearance, which barely affects daily social interactions or aesthetics. Without the brackets and wires of traditional metal braces, they do not irritate the oral mucosa, resulting in minimal foreign body sensation and high comfort. They can be removed independently during meals for easy teeth cleaning, reducing the risk of cavities and gingivitis. They are suitable for people who prioritize aesthetics and convenience when undergoing orthodontic treatment.

[0003] For example, patent (CN211590205U) discloses a cutting and punching device for attaching elastic bands to bracketless clear aligners. It describes a device that includes a scissor body with two blades that cross and hinge at the middle. Two cutting edges on the two blades rotate around the hinge point to achieve cutting. The cutting and punching device also includes a punching component, which includes a punching head and a receiving opening. The punching head is located at the non-hinge end of one blade, and the receiving opening is located at the non-hinge end of the other blade. The punching head and the receiving opening move with the blades and interlock to punch a hole in the aligner wall between them. When the punching head is inserted into the receiving opening, the two blades contact each other to make a cut in the aligner wall between them. This cutting and punching device for attaching elastic bands to bracketless clear aligners has advantages such as simplicity, practicality, convenient operation, stable fixation, reduced aligner removal, and no restrictions on operating space or equipment.

[0004] When using the above technology, the following technical problems were found in the existing technology: However, the small round pieces generated by the above device will randomly scatter on the operating table, instrument gaps, orthodontic appliance surface and around the workbench. Due to their small size, large number and light weight, they are difficult to quickly collect and clean after scattering. They need to be picked up or swept manually one by one, resulting in pollution of the operating environment. Utility Model Content

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] Example 1 like Figure 1 - Figure 5 As shown, a drilling device for invisible aligners includes a handle a101 and a handle b102. A rotating block a103 is fixedly connected to the end of the handle a101, and a rotating block b104 is fixedly connected to the end of the handle b102. A rotating shaft 105 is fixedly connected to one end of the rotating block a103 near the rotating block b104. The rotating block b104 is located outside the rotating shaft 105 and rotatably connected to it. A fixing block a106 is fixedly connected to the end of the rotating block b104 away from the handle b102. A fixing block b107 and a storage box 108 are fixedly connected to the end of the rotating block b104 away from the handle b102. The fixing block b107 is located at the lower end of the storage box 108. A storage base 109 is provided at the lower end of the storage box 108.
