Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a self-locking bracket for adaptive ligation. Background Technology

[0002] In the field of orthodontic instruments, self-ligating brackets are one of the core instruments in modern orthodontics. They use built-in locking mechanisms to fix the orthodontic archwire, replacing the ligatures or rubber bands required by traditional brackets. Compared to traditional brackets, self-ligating brackets theoretically provide lower friction, potentially leading to faster tooth movement, gentler corrective forces, and longer intervals between appointments. Therefore, they are widely used in orthodontic treatment. However, existing traditional passive self-ligating brackets have significant shortcomings. Their locking plates are small, creating numerous gaps when fitted with the bracket body. These gaps easily trap food debris, making cleaning difficult and potentially causing oral hygiene problems, thus affecting the safety of the treatment process. Simultaneously, existing overlay passive self-ligating brackets also have drawbacks that urgently need to be addressed. Their limited ligation space and lack of four prominent wing structures make ligation operations inconvenient, affecting the convenience and efficiency of orthodontic treatment. These problems negatively impact the effectiveness and user experience of self-ligating brackets and urgently require improvement through structural design optimization. In view of this, a self-locking bracket for adaptive ligation is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a self-locking bracket for adaptive ligation, which can achieve adaptive ligation.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An adaptive ligation self-locking bracket includes a bracket body and a self-locking sliding cover. The self-locking sliding cover is slidably disposed on the bracket body. The bracket body has a wire groove. The side of the self-locking bracket has a first groove and a second groove. The first groove extends from the upper surface of the self-locking sliding cover to the bracket body. The first groove and the second groove are in opposite positions. The first groove and the second groove have a recessed groove. A fixing piece is disposed in the recessed groove. The top of the fixing piece has a ligation limiting protrusion. The ligation limiting protrusions are arranged in pairs. The ligation limiting protrusions of the same pair are symmetrically arranged about the central axis of the recessed groove. A ligation limiting interval is formed between the ligation limiting protrusions of the same pair. The protrusion heights of the ligation limiting protrusions of the same pair are the same. The protrusion heights of different pairs of ligation limiting protrusions are arranged in descending order of height on the same side of the central axis of the recessed groove.

[0005] In a preferred embodiment, the support body is provided with a slider, the slider is L-shaped, and the self-locking sliding cover is provided with a groove that cooperates with the slider.

[0006] In a preferred embodiment, the support body is provided with a mounting hole, a positioning rod is provided in the mounting hole, and a limiting groove is provided at the bottom of the self-locking sliding cover, and the positioning rod is inserted into the limiting groove.

[0007] In a preferred embodiment, the upper surface of the self-locking sliding cover and the upper surface of the support body form a common upper surface, and an opening groove is provided on the upper surface, the opening groove being located on the support body.

[0008] In a preferred embodiment, except for the ligation limiting protrusion furthest from the central axis of the sinking trough, the top of the other ligation limiting protrusions on the side furthest from the central axis of the sinking trough is provided with a protruding sharp portion.

[0009] In a preferred embodiment, the ligation limiting protrusion is elongated, and the top edge of the ligation limiting protrusion has an arc-shaped chamfer.

[0010] Compared with existing technologies, this utility model provides an adaptive ligation self-ligating bracket. The bracket body and a sliding self-ligating cover cooperate with each other. The opening and closing of the wire groove is achieved by the sliding of the self-ligating cover along the bracket body. This provides a convenient channel for the insertion and placement of the orthodontic archwire and reliably limits the archwire, ensuring stable transmission of corrective force during treatment. The self-ligating bracket features a first groove and a second groove opposite each other on its side, with the first groove extending from the upper surface of the self-ligating cover to the bracket body. This structural layout naturally forms four distinct wing structures on the side of the bracket, effectively solving the problems of insufficient ligation space and lack of obvious wing structures in traditional overlay passive self-ligating brackets, thus providing ample space and convenient force support for ligation operations. The recesses within the first and second grooves provide suitable installation and support space for the fixation piece, stably limiting its movement in the dynamic oral environment and ensuring the stability of the ligation assistance effect. The ligation limiting protrusions on the top of the fixation piece are arranged in pairs, with the same pair facing the recesses. The symmetrical design along the central axis utilizes the mechanical properties of symmetrical structures to evenly distribute the force during ligation, avoiding localized stress concentration. It also ensures the fixation plates are installed correctly, providing symmetrical constraints on the ligature wires and guaranteeing the accuracy of the ligature wire's positioning. The identical height of each pair of ligature limiting protrusions creates a regularly spaced ligature limiting interval, providing a stable and suitable constraint space for the ligature wires and preventing loosening or displacement within the interval. Different pairs of ligature limiting protrusions have varying heights, and the protrusions on the same side of the central axis of the groove are arranged from high to low. This structural design principle constructs multiple levels of ligature limiting intervals of different specifications. It allows for quick selection of the appropriate limiting interval based on different diameters, types of ligature wires, and diverse ligation needs, achieving adaptive ligation without the need for additional fixation components. This improves operational convenience, ensures balanced ligation force, and guarantees the directional and uniform transmission of corrective force. The overall structure balances adaptability, stability, and operational convenience, effectively optimizing the ligation experience of the self-locking bracket. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0023] like Figures 1 to 9As shown, an adaptive ligation self-locking bracket includes a bracket body 1 and a self-locking sliding cover 7. The self-locking sliding cover 7 is slidably disposed on the bracket body 1. The bracket body 1 is provided with a wire groove 6. The side of the self-locking bracket is provided with a first groove 10 and a second groove 11. The first groove 10 extends from the upper surface of the self-locking sliding cover 7 to the bracket body 1. The first groove 10 and the second groove 11 are in opposite positions. The first groove 10 and the second groove 11 are provided with a recessed groove 12. The recessed groove 12 is provided with a fixing piece 16. The top of the plate 16 is provided with a ligation limiting protrusion 17. The ligation limiting protrusion 17 is arranged in pairs. The ligation limiting protrusion 17 of the same pair is symmetrically arranged about the central axis 13 of the sink 12. A ligation limiting interval 23 is formed between the ligation limiting protrusion 17 of the same pair. The protrusion height of the ligation limiting protrusion 17 of the same pair is the same. The protrusion height of the ligation limiting protrusion 17 located on the same side of the central axis 13 of the sink 12 is arranged in descending order of height.

[0024] This embodiment of an adaptive ligation self-locking bracket includes a bracket body 1 and a slidably mounted self-locking cover 7 that cooperate with each other. The self-locking cover 7 slides along the bracket body 1 to open and close the wire groove 6, providing a convenient channel for the insertion and placement of the orthodontic archwire 24, and reliably limiting the archwire 24 to ensure stable transmission of corrective force during treatment. A first groove 10 and a second groove 11 are arranged opposite each other on the side of the self-locking bracket, with the first groove 10 extending from the upper surface of the self-locking cover 7 to the bracket body 1. This structural layout allows the bracket side to... The four distinct wing structures effectively solve the problems of insufficient ligation space and inconvenience caused by the lack of obvious wing structures in traditional cover-type passive self-locking brackets, providing ample space and convenient force support for ligation operations; the recessed grooves 12 in the first groove 10 and the second groove 11 provide a suitable installation and bearing space for the fixation piece 16, which can stably limit the fixation piece 16 and prevent it from shifting in the dynamic environment of the oral cavity, ensuring the stability of the ligation assistance effect; the ligation limiting protrusions 17 on the top of the fixation piece 16 are arranged in pairs and are in the same pair. The design, symmetrical to the central axis 13 of the settling tank 12, utilizes the mechanical properties of a symmetrical structure to evenly distribute the force during ligation, avoiding localized stress concentration. Simultaneously, it ensures the proper installation of the fixing plate 16, forming a symmetrical constraint on the ligature wire and guaranteeing the accuracy of the ligature wire's positioning. The same pair of ligature limiting protrusions 17 have the same height, forming a regularly spaced ligature limiting interval 23, providing a stable and suitable constraint space for the ligature wire and preventing loosening or displacement within the interval. Different pairs of ligature limiting protrusions 17 have varying heights, and... The protrusions on the same side of the central axis 13 of the recess 12 are arranged from high to low. The structural design principle is to construct multiple levels of ligation limiting intervals 23 of different specifications. According to different diameters and types of ligation wires and diverse ligation needs, the appropriate limiting interval can be quickly selected. Adaptive ligation can be achieved without the need to replace the fixing parts. This not only improves the convenience of operation, but also ensures the balanced force of ligation and guarantees the directional and uniform transmission of orthodontic force. The overall structure takes into account adaptability, stability and ease of operation, and effectively optimizes the ligation experience of self-locking brackets.

[0025] In this embodiment, the height of the ligation limiting protrusion 17 is set between 0.2 and 0.5 mm.

[0026] In this embodiment, the sink 12 is provided with a positioning hole 14, and the edge of the positioning hole 14 is provided with a hook ring 15. The bottom of the fixing plate 16 is provided with a fixing cylinder 19, which is inserted into the positioning hole 14. The fixing cylinder 19 includes multiple segments 20, and the lower end of each segment 20 is provided with a hook edge 21. The fixing cylinder 19 is provided with a shape memory alloy wire 22, and the hook edge 21 and the hook ring 15 are connected together. The cooperation between the fixing tube 19 and the positioning hole 14 provides the basic structure for the installation and adjustment of the fixing piece 16. The bidirectional memory alloy wire 22 utilizes its temperature response characteristics to expand under the suitable temperature in the oral cavity, causing the segments 20 of the fixing tube 19 to open. This allows the hook edge 21 at the lower end of the segment 20 to be firmly connected to the hook ring 15 on the edge of the positioning hole 14, thus achieving reliable fixation of the fixing piece 16. The fixation operation can be completed without additional tools, making it suitable for use in the oral cavity. When it is necessary to adjust or replace the fixing piece 16, the memory alloy wire 22 can be contracted by exposing the fixing piece 16 or cooling it with cold air. The self-restoring force of the segment 20 or the contraction force of the memory alloy wire 22 can release the hook edge 21 from the hook ring 15, thereby making it easy to pull the fixing tube 19 out of the positioning hole 14, achieving convenient disassembly and replacement of the fixing piece 16.

[0027] Furthermore, there are two or more positioning holes 14, which are symmetrically arranged about the central axis 13 of the sink 12. The fixing cylinder 19 corresponds one-to-one with each positioning hole 14. Both the positioning holes 14 and the ligation limiting protrusions 17 are symmetrically arranged about the central axis 13 of the sink 12, ensuring even force distribution, optimizing structural mechanical properties, and avoiding localized stress concentration. The fixing plate 16 is installed more stably and neatly, and the ligation wire is precisely limited by symmetrical constraints, ensuring directional and uniform transmission of corrective force.

[0028] Furthermore, the support body 1 is provided with a slider 2, which is L-shaped, and the self-locking sliding cover 7 is provided with a groove 8 that cooperates with the slider 2. The L-shaped slider 2 and the groove 8 are precisely matched, providing strong guidance and smooth sliding. This can stably constrain the movement trajectory of the self-locking sliding cover 7, improve the reliability of its switch screw groove 6, prevent deviation or loosening during sliding, and ensure stability in use.

[0029] Furthermore, the support body 1 is provided with a mounting hole 3, and a positioning rod 4 is provided in the mounting hole 3. The bottom of the self-locking sliding cover 7 is provided with a limiting groove 9, and the positioning rod 4 is inserted into the limiting groove 9. The positioning rod 4 and the limiting groove 9 are precisely matched, which can reliably limit the sliding stroke of the self-locking sliding cover 7, avoid overtravel displacement, and at the same time assist in guidance, ensuring the accurate and stable operation of its switch screw groove 6.

[0030] Furthermore, the upper surface of the self-locking sliding cover 7 and the upper surface of the tray 1 form a common upper surface, and an opening groove 5 is provided on the upper surface of the tray 1. The self-locking sliding cover 7 and the upper surface of the tray 1 form a flat common upper surface, which is seamless and has good coverage, effectively reducing food residue residue; the opening groove 5 on the tray 1 alone facilitates opening the sliding cover, taking into account both cleanliness and ease of use.

[0031] Furthermore, except for the ligation limiting protrusion 17 furthest from the central axis 13 of the sink 12, the other ligation limiting protrusions 17 have protruding sharp portions 18 on the top of the side furthest from the central axis 13 of the sink 12. The protruding sharp portions 18 allow for positioning of the ligation wire when it is located on top of these protrusions. For example, the ligation wire is positioned within the ligation limiting interval 23 between the outermost ligation limiting protrusion 17 and the pair of ligation limiting protrusions 17. Within this interval, the protruding sharp portions 18 of the ligation limiting protrusions 17 can abut against the ligation wire, thus providing auxiliary fixation and preventing displacement or slippage of the ligation wire within the interval. Combined with multi-level limiting intervals of different heights, this accurately adapts to the positioning requirements of ligation wires of different specifications while ensuring stable ligation force.

[0032] Furthermore, the ligation limiting protrusion 17 is configured as an elongated strip, and the top edge of the ligation limiting protrusion 17 is provided with an arc-shaped chamfer, which can achieve a good limiting effect on the ligation wire.

[0033] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be easily made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
