Description

Technical Field

[0001] The utility model relates to the field of oral orthodontics, in particular to a self-locking bracket unlocking device. Background Art

[0002] Self-ligating brackets are commonly used in orthodontic treatment. They have a unique self-locking structure that secures the archwire securely in place after insertion, eliminating the need for additional ligatures or rubber bands.

[0003] A common type of self-ligating bracket currently in use is the sliding cover type. The bracket body is designed with a slide rail, and a locking cover slides back and forth on the bracket body, thereby achieving self-locking and unlocking of the bracket. However, these sliding cover type self-ligating brackets often experience occlusal interference and a strong foreign body sensation. In response to this, the applicant has independently developed and filed a patent application for a new type of rotating self-ligating bracket, which features easier archwire insertion, less foreign body sensation during wear, and improved comfort. For more information, please refer to China Publication No. CN118340591A - Self-ligating Bracket.

[0004] Since the volume and size of self-ligating brackets are very small, it is difficult for doctors to open or close the cover without corresponding auxiliary tools. In clinical practice, doctors are faced with different types of self-ligating brackets when treating different patients. Due to differences in structural characteristics and unlocking methods, doctors have to switch to different unlocking tools accordingly. As a result, the various equipment and identification are cumbersome, and the operation is prone to confusion and errors. On the other hand, while wearing braces, it is difficult for patients to clean their teeth properly during daily brushing and maintain oral hygiene. Tartar easily accumulates around the brackets, increasing the difficulty of unlocking the self-ligating brackets. Utility Model Content

[0030] See Figure 2-Figure 6 The present invention discloses a multi-purpose self-locking bracket unlocker, which includes a handle body 10, a first locking pin 20, and a second locking pin 30. The handle body 10 is a long strip structure suitable for handholding, and its two opposite sides are respectively a first half 11 and a second half 12. The ends of the first half 11 and the second half 12 are respectively fixed with the first locking pin 20 and the second locking pin 30. Figure 2-Figure 3 The end of the first locking pin 20 is a needle-like structure with a conical shape, suitable for being inserted into the locking hole of the existing sliding self-locking bracket; Figure 4-Figure 5 The end of the second locking pin 30 is a boss-like structure, suitable for insertion into the lock hole 2 of the applicant's independently developed rotating self-locking bracket 1 and for levering the lock cover 3 to rotate. Specifically, the end of the second locking pin 30 is shaped like a quadrangular pyramid, which can be a rectangular parallelepiped or trapezoidal. This shape is easy to manufacture and provides stable contact force when levering the lock cover 3, preventing it from slipping. The first locking pin 20, on the other hand, adopts a pointed needle-like structure, which is highly versatile and can be inserted into lock holes of basically any shape.

[0031] The working principle of this utility model is:

[0032] The first half 11 and the second half 12 at both ends of the handle body 10 are respectively designed with a first locking pin 20 and a second locking pin 30, wherein the end of the first locking pin 20 is a needle-shaped tip, which is suitable for unlocking most existing self-locking brackets (including reciprocating sliding self-locking brackets). The first locking pin 20 is inserted into the lock hole and the lock cover is pushed to open the bracket; the second locking pin 30 is suitable for the rotating self-locking bracket 1 independently developed by the applicant (see China Public Invention CN118340591A-Self-locking Bracket, Appendix to the Instruction Manual) Figure 6 ), see Figure 1 and Figure 5 , insert the boss-shaped end of the second locking pin 30 downward into the lock hole 2 of the self-locking bracket, pry the lock cover 3 and rotate it backward to open the bracket lock cover 3. While unlocking, you can also pry the dental plaque accumulated around the bracket to make it fall off.

[0033] It should be noted that Figure 1The locking hole 2 of the rotating self-locking bracket 1 is semicircular. Here, a semicircular reinforcing rib is designed to make the circumferential position connection of the locking hole 2 of the locking cover 3 more stable. The second locking pin 30 in the shape of a boss only needs to be large enough to be inserted into the locking hole 2. The shapes of the second locking pin 30 and the locking hole 2 do not need to be tightly matched.

[0034] As an integrated orthodontic auxiliary tool, the present invention can be used to open or close different types of self-ligating brackets, enjoying wide application and high versatility. In practice, the physician only needs to be equipped with one unlocking tool, eliminating the need for multiple auxiliary instruments. This reduces confusion and errors during handling, saving the physician's energy. Furthermore, while unlocking the rotating self-ligating bracket 1, dental calculus around the locking cover 3 can be removed, ensuring oral hygiene.

[0035] The unlocking tool can be a one-piece structure, where the first half 11 and the second half 12 of the handle body 10 can be integrally formed or fixedly connected. In another embodiment, the unlocking tool can also be a split structure, for example, the first half 11 and the second half 12 can be rotated together using internal and external threads, or can be connected in a sleeve-type manner. In this way, the unlocking tool can be split into two unlocking tools for easy storage, and can also be connected as a whole for use.

[0036] Preferably, the first locking pin 20 is further bent so that the end of the first locking pin 20 is tilted relative to the horizontal direction. This tilt angle makes it easier for the physician to use the end of the first locking pin 20 to pry the locking cover of the self-ligating bracket while holding the handle body 10.

[0037] Similarly, the second locking pin 30 is also bent with a bend, so that the end of the second locking pin 30 is tilted relative to the horizontal direction. Similarly, such an inclination angle makes it easier for the doctor to use the end of the second locking pin 30 to pry the lock cover 3 while holding the handle body 10.

[0038] Further, see Figure 6 Along the radial direction of the handle body 10, the ends of the first locking pin 20 and the second locking pin 30 are arranged opposite each other. In this way, when the doctor needs to switch the unlocking end, for example, when the doctor finds that the locking pin used does not match the bracket type during unlocking and needs to switch from the first locking pin 20 to the second locking pin 30, the doctor only needs to rotate the handle body 10 with one hand, and the end of the second locking pin 30 will directly face the locking hole 2 without additional adjustment.

[0039] In order to prevent the lock cover from slipping and loosening when being pried, preferably, a plurality of anti-skid threads 40 arranged at even intervals are machined on the first half 11. Similarly, a plurality of anti-skid threads 40 arranged at even intervals are also machined on the second half 12.

[0040] When holding the unlocking tool, the doctor usually holds the first locking pin 20 or the second locking pin 30 with his fingers, while holding the handle body 10 with the remaining fingers and palm. To improve the grip and stability, a groove 50 is formed at the connection between the first half 11 and the second half 12. The groove 50 facilitates the operator's fingers and palm to hold the handle body 10 stably.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
