Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a magnetic orthodontic archwire fixation device. Background Technology

[0002] Orthodontics is a discipline that studies the etiology, diagnosis, prevention and treatment of malocclusion. Among them, fixed orthodontic techniques are currently the most widely used methods in clinical practice. One of the core components of fixed orthodontic technology is the orthodontic bracket, which is fixed to the tooth surface with adhesive. It has grooves to accommodate and guide the archwire. The archwire, as the force source, applies continuous and gentle biological force to the teeth in cooperation with the bracket, thereby achieving the purpose of moving the teeth and aligning the teeth.

[0003] In some existing techniques, the archwire is fixed in the bracket groove using thin metal ligatures or elastic ligatures. However, whether tightening the ligatures or stretching the ligatures, the doctor needs to perform delicate and repetitive operations in the narrow oral space. This greatly prolongs the clinical operation time, increases the doctor's workload and fatigue, and the ends of the metal ligatures, even after being bent and cut, may still form sharp protrusions that can easily puncture or rub against the patient's oral mucosa, tongue, or cheek soft tissue, causing ulcers, pain, and other discomfort, affecting the patient's quality of life during orthodontic treatment. Utility Model Content

[0004] The main objective of this invention is to provide a magnetic orthodontic archwire fixation device, which effectively solves the problem mentioned above. In some existing technologies, the archwire is often fixed in the bracket groove using thin metal ligatures or elastic ligatures. However, whether tightening the ligatures or stretching the ligatures, doctors need to perform delicate and repetitive operations in the confined oral cavity. This greatly prolongs the clinical operation time, increases the doctor's workload and fatigue, and the ends of the metal ligatures, even after being bent and cut, may still form sharp protrusions that can easily puncture or rub against the patient's oral mucosa, tongue, or cheek soft tissue, causing ulcers, pain, and other discomfort, thus affecting the patient's quality of life during orthodontic treatment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A magnetic orthodontic archwire fixing device includes a fixing plate, a bracket seat installed at the rear end of the fixing plate, an arc-shaped wire groove installed in the middle of the inner surface of the bracket seat, a clamping component provided at the rear end of the arc-shaped wire groove, a rotating component installed on the upper side of the front end of the clamping component, a preliminary clamping component installed on the lower side of the front end of the clamping component, and a fixing component installed together on the rear side of the inner surface of the bracket seat and the clamping component.

[0006] Preferably, the clamping assembly is engaged with the bracket seat, and the arc-shaped wire groove and the opposite side of the clamping assembly are provided with bow wires.

[0007] Preferably, the clamping assembly includes a cross cover plate, and an arc-shaped wire groove is provided in the middle of the front end of the cross cover plate.

[0008] Preferably, the rotating assembly includes two support blocks, which are arranged symmetrically from left to right. The front ends of the two support blocks are respectively installed on the left and right sides of the upper rear end of the fixed adhesive plate. A threaded shaft is installed on the opposite surfaces of the two support blocks, and a threaded sleeve is threadedly connected to the outer surface of the threaded shaft.

[0009] Preferably, the fixing component includes a threaded groove, and the rear side of the inner surface of the bracket and the cross cover plate are jointly provided with a threaded groove, and a right countersunk groove is provided on the left end of the bracket near the threaded groove.

[0010] Preferably, the inner surface of the threaded groove is threaded with a threaded rod, and a mounting bracket is installed at the left end of the threaded rod, the mounting bracket being disposed inside the right sinker.

[0011] Preferably, a limiting disc is provided at the right end of the threaded rod, and the limiting disc is directly injection molded on the right end of the bracket near the threaded groove.

[0012] Preferably, the initial snap-fit ​​assembly includes a snap-fit, which is installed on the lower side of the front end of the cross cover plate. The front side of the outer surface of the snap-fit ​​is engaged with a slot seat, which is installed on the lower side of the rear end of the fixing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This device utilizes a specially designed clamping component that engages with the "+" shaped clamping seat of the bracket. By placing the archwire between the second and first curved wire grooves, the archwire can be positioned, eliminating the cumbersome traditional ligation method. This significantly shortens clinical operation time and reduces the workload of doctors. Furthermore, the integrated clamping component eliminates the sharp ends of traditional ligature wires, preventing damage to the oral mucosa. At the same time, its smooth surface and integrated structure facilitate oral cleaning, significantly improving patient comfort and oral health during orthodontic treatment. This device employs a design with a fixing component and a preliminary locking component. These components work together to quickly and accurately position the locking component, freeing the doctor's hands and solving the problems of difficult thread alignment and easy slippage in the confined space of the oral cavity. The fixing component then performs the final thread tightening, ensuring the connection's firmness. By integrating the convenience of the snap-fit ​​with the reliability of the threads, this device achieves a high degree of consistency between ease of operation and structural reliability in actual use.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Example 1, as Figure 1 As shown, a magnetic orthodontic archwire fixing device includes a fixing plate 1, a bracket seat 2 installed at the rear end of the fixing plate 1, an arc-shaped wire groove 3 installed in the middle of the inner surface of the bracket seat 2, a clamping component 4 provided at the rear end of the arc-shaped wire groove 3, a rotating component 6 installed on the upper side of the front end of the clamping component 4, a preliminary clamping component 8 installed on the lower side of the front end of the clamping component 4, and a fixing component 7 jointly installed on the rear side of the inner surface of the bracket seat 2 and the clamping component 4.

[0018] In this embodiment, firstly, a pre-clamping component 8, with an elastic snap-fit ​​structure, achieves a quick and precise initial connection between the clamping component 4 and the bracket seat 2, solving the problem of alignment and fixation in a narrow and slippery oral cavity. Subsequently, a threaded fixing component 7 further tightens and securely locks the pre-positioned clamping component 4 onto the bracket seat 2, thereby stably confining the archwire 5 within the preset groove. This design combines the convenience of snap-fit ​​with the reliability of threaded connection, significantly improving the efficiency of clinical operation and the stability of final fixation.

[0019] For details, please refer to Figure 1 and Figure 2 In this embodiment, the clamping assembly 4 is engaged with the bracket 2, and the arc-shaped wire groove 3 and the opposite side of the clamping assembly 4 are provided with bow wire 5. Further reference Figure 1 and Figure 4 In this embodiment, the clamping assembly 4 includes a cross cover plate 401, and an arc-shaped wire groove 402 is provided in the middle of the front end of the cross cover plate 401. First, the dentist firmly attaches the fixing plate 1 to the patient's tooth surface with adhesive. At this time, the bracket 2 is fixed to the tooth along with the fixing plate 1. When it is necessary to install the archwire 5, the dentist places the archwire 5 into the arc-shaped groove 3 on the inner surface of the bracket 2. The dentist uses a special tool or fingers to rotate and press the clamping component 4, namely the cross cover plate 401, and aligns it with the bracket 2 to initially limit the archwire 5. The clamping component 4 engages with the "+" shaped clamping seat of the bracket 2, and the archwire 5 is placed between the arc-shaped wire groove 2 402 and the arc-shaped wire groove 3 to limit the archwire 5. This eliminates the cumbersome traditional ligation method, greatly shortens the clinical operation time, and reduces the workload of doctors. In addition, the integrated clamping component 4 eliminates the sharp ends of traditional ligature wires, avoiding damage to the oral mucosa. At the same time, its smooth surface and integrated structure are more conducive to oral cleaning, significantly improving the patient's comfort and oral health during orthodontic treatment.

[0020] Example 2: Based on Example 1, this example adds a rotating component 6, a fixing component 7, and a preliminary locking component 8 for installing and fixing the clamping component 4 and the bracket 2. By setting the rotating component 6, the fixing component 7, and the preliminary locking component 8, the convenience of the buckle and the reliability of the thread are integrated, achieving a high degree of unity between the convenience of operation and the structural reliability in actual use.

[0021] For details, please refer to Figure 1 , Figure 4 and Figure 5In this embodiment, the rotating component 6 includes two support blocks 601. The two support blocks 601 are arranged symmetrically from left to right. The front ends of the two support blocks 601 are respectively installed on the left and right sides of the upper rear end of the fixed adhesive plate 1. The opposing surfaces of the two support blocks 601 are jointly installed with a threaded shaft 602. The outer surface of the threaded shaft 602 is threadedly connected with a threaded sleeve 603. Further reference Figure 1 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the fixing component 7 includes a threaded groove 701. The rear side of the inner surface of the bracket 2 and the cross cover plate 401 are jointly provided with the threaded groove 701. The left end of the bracket 2 is provided with a right countersunk groove 702 near the threaded groove 701. The inner surface of the threaded groove 701 is threadedly connected with a threaded rod 703. The left end of the threaded rod 703 is equipped with a mounting bracket 704. The mounting bracket 704 is located inside the right countersunk groove 702. The right end of the threaded rod 703 is provided with a limiting disc 705. The limiting disc 705 is directly injection molded onto the right end of the bracket 2 near the threaded groove 701. Further reference Figure 1 , Figure 4 and Figure 5 In this embodiment, the initial snap-fit ​​assembly 8 includes a snap-fit ​​801, which is installed on the lower side of the front end of the cross cover plate 401. The front side of the outer surface of the snap-fit ​​801 is engaged with a slot seat 802, which is installed on the lower side of the rear end of the fixing adhesive plate 1. The doctor uses a special tool or fingers to rotate the clamping assembly 4, namely the cross cover plate 401, and aligns it with the bracket seat 2. Since the threaded sleeve 603 and the threaded shaft 602 fixed on the support block 601 form a threaded pair, the rotational motion will be converted into linear motion. When the threaded sleeve 603 is rotated clockwise, it will move backward along the threaded shaft 602, that is, towards the teeth. This backward pulling force is transmitted through the cross cover plate 401 to the entire clamping assembly 4, so that it is firmly pulled backward until it fits the bracket seat 2 completely. In this process, the key operation is to use the initial snap-fit ​​component 8 to achieve rapid positioning. The buckle 801 installed on the lower front side of the cross cover plate 401 is aligned and pressed into the slot seat 802 on the lower rear side of the fixed adhesive plate 1. Since the buckle 801 and the slot seat 802 are made of medical plastic material with a certain elasticity, the buckle 801 undergoes elastic deformation under pressure and successfully snaps into the slot seat 802, and then returns to its original state, producing a clear "click" sound and tactile feedback. The clamping component 4 is quickly and stably "hung" on the bracket 2, freeing the doctor's hands from continuous hand support, creating conditions for subsequent thread tightening and avoiding problems such as thread stripping or misalignment in the narrow oral cavity. After the clamping assembly 4 is initially fixed to the bracket 2 by the initial clamping assembly 8, an external rotating tool can be used to clamp it into the inner side of the mounting bracket 704, and the threaded rod 703 is also screwed into the depth of the threaded groove 701, so that the right end of the threaded rod 703 contacts the limiting disc 705, and the left end of the mounting bracket 704 will be completely sunk into the right recess 702 of the side wall of the bracket 2, forming a plane. This design allows the threaded rod 703 to lock the cross cover plate 401 and the bracket 2 tightly together after being tightened, preventing loosening or separation in any direction. At this point, the entire locking process is complete. The arc-shaped wire groove 402 on the clamping assembly 4 and the arc-shaped wire groove 3 on the bracket 2 together form a cavity that can limit the position of the bowwire 5, thus firmly confining the bowwire 5 within it. The fixing component 7 and the preliminary snap-fit ​​component 8 work together. First, the preliminary snap-fit ​​component 8 enables the quick and accurate pre-positioning of the snap-fit ​​component 4, freeing up the doctor's hands and solving the problem of difficult thread alignment and easy slippage in the narrow space of the oral cavity. Then, the fixing component 7 performs the final thread tightening, ensuring the firmness of the connection. By integrating the convenience of the snap-fit ​​with the reliability of the thread, the convenience of operation in actual use and the high degree of structural reliability are achieved.

[0022] When disassembling, simply follow the reverse steps described above.

[0023] Both the buckle 801 and the card slot 802 in this solution can be made of medical plastic material in the prior art, which has a certain degree of elasticity and can realize the relative snap-fit ​​connection between the buckle 801 and the card slot 802. Since it is a very mature product in the prior art, it will not be described in detail in this application.
