Description

Technical Field

[0001] This utility model relates to the field of orthodontic instruments, specifically to an ultra-thin strip arch bracket. Background Technology

[0002] In the field of orthodontic technology, ribbon arch brackets, due to their unique structural design, can work in conjunction with ribbon archwires to achieve efficient teeth straightening. In recent years, to improve patient comfort, ultra-thin ribbon arch brackets have become a development trend. For example, the "ultra-thin perforated ribbon arch standard bracket" disclosed in patent publication number CN222150192U significantly reduces the overall thickness of the bracket by eliminating vertical grooves and holes on the bracket body, achieving ultra-thin bracket design—a positive advancement in existing technology.

[0003] However, through in-depth research and clinical practice, the applicant discovered that this relentless pursuit of ultra-thin design has led to a serious clinical operational challenge overlooked by existing technologies. To minimize bracket height, the base thickness of these ultra-thin brackets is extremely compressed, resulting in very small areas on their proximal and distal sides. More importantly, these sides are typically smooth planes, completely lacking any auxiliary structures to facilitate instrument gripping. When physicians use conventional forceps to hold these brackets for bonding, the forceps prongs cannot form an effective gripping point and friction with the smooth, small area of ​​the bracket base, making it highly susceptible to instability, slippage, or even falling. Due to the bracket's tiny size, once it falls to the ground or onto the surgical drape, it is extremely difficult to locate. This not only seriously delays treatment time and affects operational efficiency but may also lead to waste due to bracket contamination, causing significant disruption to the physician's clinical work.

[0004] Therefore, the inconvenience of clamping and the tendency to slip out of existing ultra-thin band brackets have become a bottleneck restricting their clinical application. Existing technologies (including but not limited to CN222150192U) do not address or resolve this issue. There is an urgent need in this field for an innovative solution that, while retaining the comfort advantages of ultra-thin brackets, can significantly improve their stability and reliability when clamped. Utility Model Content

[0005] In view of the above problems, this utility model provides an ultra-thin strip-shaped arch support groove to solve the problems of inconvenient clamping and easy slippage of existing ultra-thin support grooves.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultra-thin strip-shaped arch support, comprising a support body, wherein the support body comprises a base plate, a substrate, and support wings disposed on the substrate, the innovation of which is that: the near, far, and middle sides of the substrate are provided with anti-dislodgement clamping structures that facilitate tweezers to hold the support.

[0007] As a further improvement of this utility model, the anti-detachment clamping structure can be a wedge-shaped inward inclined surface that slopes inward from the top (away from the bottom plate) of the bracket base towards its bottom (near the bottom plate), with an inward inclination angle of any angle between 1° and 30°, so that the near and far sides of the base form a wedge shape that is wider at the top and narrower at the bottom.

[0008] Using a wedge-shaped inward inclined surface as an advantageous clamping structure in the anti-dislodgement clamping structure, when doctors use tweezers to clamp the ultra-thin bracket with the wedge-shaped inward inclined surface for bonding, the tweezers and the wedge-shaped inward inclined surface on the proximal and distal sides of the bracket base form an effective clamping, which is stable and not easy to slip off or fall off.

[0009] Of course, in order to better adapt to this bracket with a wedge-shaped inwardly inclined surface, we have also designed a special tweezer with a clamping end that is narrower at the front and wider at the back, which is more compatible with it. The inwardly inclined angle of the inwardly inclined clamping part of the special tweezer is slightly greater than the inwardly inclined angle of the wedge-shaped inwardly inclined surface on the proximal and distal sides of the ultra-thin strip arch bracket.

[0010] Furthermore, an anti-detachment clamping groove can be provided at the bottom of the wedge-shaped inner inclined surface near the base plate of the tray, and parallel to the base plate. This anti-detachment clamping groove is preferably an arc-shaped groove. This anti-detachment clamping groove can cooperate with the protrusion on the inner side of the clamping end of the special tweezers to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop.

[0011] Alternatively, the anti-detachment clamping structure can be independently configured as an anti-detachment clamping groove, located on the near and far sides of the substrate close to the bottom plate and parallel to the bottom plate. Similarly, this anti-detachment clamping groove is preferably an arc-shaped groove. This anti-detachment clamping groove can cooperate with the protrusion on the inner side of the clamping end of a special tweezers to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop.

[0012] Another key feature of this invention is the simultaneous provision of a dedicated tweezers for use with the aforementioned ultra-thin ribbon arch support. This dedicated tweezers includes a tweezers body with two opposing clamping arms. Its innovation lies in the fact that the front clamping portion of each arm is an inwardly inclined clamping portion, and the front clamping portions of the two opposing arms together form a clamping end that is narrower at the front and wider at the back. Its inward inclination angle is adapted to the wedge-shaped inward inclination surface of the support. Furthermore, the inner side of the clamping end is also provided with a protrusion for engaging with the anti-dislodgement clamping groove of the support.

[0013] The protrusion is preferably an arc-shaped protrusion. The inward tilt angle of the inward tilting clamping part is 1°-30°, and the inward tilt angle of the inward tilting clamping part of the special tweezers is slightly larger than the inward tilt angle of the wedge-shaped inward tilting surface on the proximal and distal sides of the ultra-thin strip-shaped arch support. The shape of the clamping part of the special tweezers is adapted to the anti-dislodgement clamping structure on the support base, which can achieve stable and reliable clamping.

[0014] The inventive concept of this utility model is not simply an isolated improvement to the tray or tweezers, but rather a creatively proposed integrated "product-tool" system solution. We recognize that to fundamentally solve the clamping challenge of ultra-thin trays, collaborative innovation is necessary from two dimensions: the "object being clamped" (the tray) and the "clamping tool" (tweezers). On the bracket, we have deviated from the norm by designing a specific anti-detachment structure (wedge-shaped surface, groove or combination thereof) on the side of its ultra-thin substrate, providing a reliable "point of force" for clamping.

[0015] Instead of relying on general-purpose tweezers, we have customized a clamping end that is precisely matched to it. The structure of "inner inclined surface + protrusion" complements the "wedge-shaped surface + groove" on the bracket.

[0016] This matching design allows the bracket and tweezers to fit together like a "key and lock," thus achieving stable clamping in one or two directions.

[0017] Compared with the prior art, the present invention has the following significant advantages: It fundamentally solves the clamping problem: by setting an anti-slip clamping structure on the side of the ultra-thin bracket base, it fundamentally changes the physical characteristics that make it difficult to clamp, so that doctors have a clear clamping point when operating, which greatly reduces the risk of slippage.

[0018] The core advantage of this invention lies in the systematic cooperation between the tray and the special tweezers.

[0019] When the wedge-shaped inner inclined surface is used in conjunction with the clamping end that is narrow at the front and wide at the back, stable clamping in the left and right directions is achieved by utilizing the inclined surface guidance and self-locking principle.

[0020] When the anti-detachment clamping groove and the inner protrusion are used together, an effective mechanical interlock is formed, which realizes reliable positioning in the front and back directions and prevents the bracket from moving or slipping.

[0021] When used in combination, the two achieve the remarkable effect of "bidirectional dual-stabilized clamping," with stability and reliability far exceeding that of a single improvement or general-purpose tool.

[0022] Improved clinical operation experience and efficiency: This utility model greatly facilitates the clinical operation of doctors, reduces the time wasted in searching for fallen brackets, reduces the doctor's operation fatigue and mental stress, and thus improves the overall efficiency and quality of orthodontic treatment.

[0023] Simple structure and easy to implement: All improvements are based on the main body structure of the tray and tweezers, without the need to add extra complex parts. The process is simple to implement and the cost is controllable, which is very conducive to industrialization and promotion. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this utility model. The embodiments and directional terms described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1To illustrate, anti-detachment clamping grooves 4 are shown on the proximal and distal sides (left and right sides) of the bracket base 2. The ultra-thin strip-shaped arch bracket includes a base plate 1, a base 2, and bracket wings 3 disposed on the base 2. Anti-detachment clamping grooves 4 (anti-detachment clamping structures) are provided on the proximal and distal sides of the base 2 to facilitate clamping by tweezers. In this embodiment, the anti-detachment clamping grooves 4 are arc-shaped grooves, disposed on the proximal and distal sides of the base 2 near the base plate 1, and parallel to the base plate 1. The anti-detachment clamping grooves 4 serve as an advantageous clamping structure in the anti-detachment clamping structure. These anti-detachment clamping grooves 4 can cooperate with the protrusions 13 on the inner side of the clamping end of the special tweezers 10 to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop.

[0027] like Figure 4 As shown, the tweezers 10 are used in conjunction with the aforementioned ultra-thin ribbon arch support groove. The tweezers 10 include two opposing clamping arms 11, the front end of which is an inwardly inclined clamping portion 12. The inwardly inclined clamping portions 12 at the front ends of the two opposing clamping arms 11 form a clamping end that is narrower at the front and wider at the back. A protrusion 13 is also provided on the inner side of this clamping end (the inwardly inclined clamping portions 12 at the front ends of the two opposing clamping arms 11). In this embodiment, the protrusion is arc-shaped, and its size is slightly smaller than the ultra-thin ribbon arch support groove 4 to facilitate automatic alignment.

[0028] The inward tilt angle of the inward tilting clamping part 12 is any angle from 1° to 15°. In this embodiment, 8° is selected. The inward tilt angle of the inward tilting clamping part 12 of the tweezers 10 is slightly larger than the inward tilt angle of the wedge-shaped inward tilting surface on the proximal and distal sides of the ultra-thin strip arch support groove.

[0029] The shape of the inwardly inclined clamping part 12 and its protrusion 13 of the tweezers 10 are adapted to the anti-detachment clamping groove 4 (anti-detachment clamping structure) on the bracket base, so as to achieve stable and reliable clamping.

[0030] In use, the dentist uses the inwardly inclined clamping part 12 of the special forceps 10 to clamp the mesial and distal sides of the bracket base 2. The inwardly inclined surface of the inwardly inclined clamping part 12 fits against the mesial and distal sides of the ultra-thin ribbon arch bracket. At the same time, the arc-shaped protrusion 13 of the special forceps 10 is inserted into the anti-slip clamping groove 4 of the bracket, thereby achieving a stable and anti-slip clamping effect, which makes it easy to accurately attach the bracket to the tooth surface. Example 2

[0031] like Figure 5As shown, the ultra-thin strip arch support includes a base plate 1, a base body 2, and support wings 3 disposed on the base body 2. The near and far sides of the base body 2 are provided with wedge-shaped inward inclined surfaces 5 (anti-detachment clamping structure) for easy gripping by tweezers. The wedge-shaped inward inclined surfaces 5 are inclined inward from the top (away from the base plate) of the support base body 2 to its bottom (close to the base plate), and the inward inclination angle is any angle within the range of 1°-15°. In this embodiment, the inward inclination angle is 5°, so that the near and far sides of the base body form a wedge shape that is wider at the top and narrower at the bottom.

[0032] like Figure 5 and Figure 6 As shown, in order to better adapt to this type of bracket with a wedge-shaped inwardly inclined surface, we have also designed a special tweezer 10 with a clamping end that is narrow at the front and wide at the back, which is more adaptable to it. The inwardly inclined angle of the inwardly inclined clamping part of the special tweezer 10 is preferably 8°, which is slightly larger than the inwardly inclined angle of the wedge-shaped inwardly inclined surface on the proximal and distal sides of the ultra-thin strip arch bracket, which is 5°.

[0033] Using a wedge-shaped inward inclined surface as an advantageous clamping structure in the anti-detachment clamping structure, when the doctor uses tweezers 10 to clamp the ultra-thin bracket with the wedge-shaped inward inclined surface for bonding, the tweezers 10 and the wedge-shaped inward inclined surface 5 on the mesial and distal sides of the bracket base 2 form an effective clamping, which is stable and not easy to slip off or fall off, making it easy to accurately bond the bracket to the tooth surface. Example 3

[0034] Further improvements were made based on the above embodiments 1 and 2. For example... Figure 7 As shown, the ultra-thin strip-shaped arch support includes a base plate 1, a substrate 2, and support wings 3. The substrate 2 has wedge-shaped inwardly inclined surfaces 5 on its proximal and distal sides. These inclined surfaces slope inward from the upper part of the substrate to the lower part at an angle of 5° (preferably selected within the range of 1°-15°). This wedge-shaped inwardly inclined surface 5 can mate with the front-narrow, rear-wide gripping end of a special tweezers 10.

[0035] like Figure 8 As shown, the near and far sides of the substrate 2 not only have wedge-shaped inwardly inclined surfaces 5, but also an arc-shaped anti-detachment clamping groove 4 at its bottom near the base plate 1, parallel to the base plate 1. This anti-detachment clamping groove 4 can cooperate with the arc-shaped protrusion 13 on the inner side of the clamping end of the special tweezers 10 to form a more effective clamping point, ensuring stable clamping and preventing slippage and drop. The special tweezers 10 (such as...) Figure 8 As shown, it includes two opposing clamping arms 11, the front clamping part of which is an inwardly inclined clamping part 12 with an inward inclination angle of 8°, forming a structure that is narrow at the front and wide at the back. The inner side of the inwardly inclined clamping part 12 is provided with an arc-shaped protrusion 13, which is slightly smaller than the anti-detachment clamping groove 4 on the bracket, so as to facilitate automatic alignment.

[0036] When in use, the dentist uses the inwardly inclined clamping part 12 of the special tweezers 10 to clamp the mesial and distal sides of the bracket base 2. The inwardly inclined surface of the inwardly inclined clamping part 12 of the tweezers 10 fits against the wedge-shaped inwardly inclined surface 5 of the bracket. At the same time, the arc-shaped protrusion 13 of the tweezers 10 is inserted into the anti-slip clamping groove 4 of the bracket, thereby achieving a stable and anti-slip bidirectional double clamping effect, which makes it easy to accurately attach the bracket to the tooth surface.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
