Description

Technical Field

[0001] This utility model relates to the field of orthodontic medical technology, specifically to a low-resistance, impact-resistant strip-shaped straight wire buccal tube and strip-shaped straight wire buccal tube forceps or pliers. Background Technology

[0002] In the field of orthodontics, the buccal tube, as a core component of fixed orthodontic appliances, is mainly used to fix the archwire, transmit corrective forces, and control three-dimensional tooth movement. In existing technology, the buccal tube typically consists of a base plate, a tube body, and traction hooks. The base plate is fixed to the tooth surface with adhesive or welded to a band, and the tube body contains an archwire channel to achieve the corrective function. However, traditional designs have the following limitations:

[0003] (1) Insufficient impact resistance

[0004] Existing buccal tubes typically consist of a base plate and a tube body, both often featuring flanges or extended structures to enhance bonding stability, such as the hook-adjustable molar buccal tube disclosed in Chinese utility model patent CN218739188U. However, this design results in a large impact surface, making it susceptible to direct impact from food during chewing, which can lead to bonding failure or detachment with prolonged use. Some improvements increase the bonding area through curved surfaces or grooves in the base plate, but these do not address the issue of dispersing external impact forces. Furthermore, the traction hooks are often independently positioned on the side of the buccal tube, causing them to protrude significantly, further increasing the impact surface and exacerbating the risk of detachment.

[0005] (2) Insufficient ease of operation

[0006] Existing buccal tubes lack a coordinated design with gripping tools. For example, the outer or lower surface of the tube is often a non-planar structure, which makes it easy to slip when gripped with general-purpose tweezers, requiring the use of complex auxiliary tools.

[0007] (3) The towing hook is not set properly.

[0008] Traditional traction hooks are positioned on the side of the buccal tube or installed independently, causing them to protrude beyond the tube's contour. This not only increases the impact surface and the risk of food impact but also easily scratches the oral mucosa, reducing patient comfort. Current technology has not resolved the contradiction between traction hook placement and impact resistance / comfort.

[0009] Furthermore, in existing technologies, buccal tube forceps typically achieve stable operation by clamping a traction hook or adapting to the outer contour of the buccal tube. For example, utility model patent CN2023219599211 discloses a buccal tube forceps that uses an L-shaped groove (vertical and horizontal sections) to clamp the traction hook, utilizing the geometric fit between the groove and the traction hook to prevent slippage. Another example is a highly stable buccal tube forceps disclosed in utility model patent CN2021228836857, which uses a snap ring and spring structure to clamp the holes on both sides of the buccal tube, combined with a scale to control the bonding height. Yet another example is a special orthodontic forceps for buccal tubes disclosed in utility model patent CN2016201956182, which uses a double-curved beak tip and an anti-slip texture design to fit the gap below the buccal tube hook. Therefore, it appears that existing technologies do not disclose forceps structures that directly utilize the archwire channel for insertion.

[0010] In summary, current buccal tube technology primarily focuses on improving adhesive strength, archwire friction, and local morphological adaptation. However, significant shortcomings remain in impact-resistant structural design (such as streamlined curved surfaces), ease of operation (planar clamping surfaces), and functional integration (combination of traction hooks and impact resistance). Furthermore, existing buccal tubes lack compatibility designs with clamping tools (such as forceps), and mismatched clamping surfaces can easily lead to installation errors. Simultaneously, the exposed layout of the traction hooks further increases the impact surface, affecting impact resistance and patient comfort. These deficiencies directly impact treatment efficiency and patient comfort, necessitating optimization through structural innovation. Utility Model Content

[0011] In view of the above problems, this utility model provides a low-resistance, impact-resistant strip-shaped straight wire buccal tube, which mainly solves the problem that traditional buccal tubes are easily detached by food impact. It also provides a strip-shaped straight wire buccal tube tweezers or pliers, which solves the problem of unstable point contact or easy slippage when the traditional tweezers hold the traction hook or hold the outer contour by cooperating with the insertion end and the plane clamp.

[0012] The technical solution of this utility model is: a low-resistance, impact-resistant strip-shaped straight wire bowstring tube, comprising a bowstring tube body, wherein the bowstring tube body is laterally provided with a bowstring channel penetrating its interior, wherein:

[0013] The buccal tube's inner surface faces the teeth, its outer surface faces away from the teeth, its upper surface faces towards the occlusal surface, and its lower surface faces towards the gum line. The inner surface of the buccal tube serves as the bonding surface for fitting the teeth; that is, the inner surface of the buccal tube is directly machined as the bonding surface, eliminating the need for a base plate structure in traditional buccal tubes. The upper edge of the bonding surface is flush with the side of the buccal tube, without any protruding flange. The upper outer surface of the buccal tube near the occlusal surface is a streamlined arc-shaped surface, which smoothly transitions downwards from the top of the buccal tube. This design helps reduce the impact surface, avoiding direct impact from food during chewing and preventing bonding failure or detachment with long-term use.

When viewed from the front side, the outer contour of the cheek tube is crescent-shaped or cashew-shaped, which can be called a full-arc low-resistance impact-resistant strip straight wire bow cheek tube.

[0018] Preferably, the radius of curvature of the streamlined arc surface is adapted to the curvature of the occlusal surface and the outer surface of human teeth.

[0019] Preferably, at least one drainage ditch is provided on the streamlined arc surface along the vertical direction.

[0020] Another technical solution of this utility model is: a strip-shaped straight wire buccal tube forceps, including a forceps body, the forceps body being composed of two clamping arms, the two clamping arms being a first clamping arm and a second clamping arm respectively;

[0021] The clamping end of the first clamping arm is provided with an insertion end, the cross-sectional shape of which matches the cross-sectional shape of the archwire channel of the cheek tube, and is used to insert into the archwire channel;

[0022] The clamping end of the second clamping arm is provided with a planar clamping part. The clamping surface of the planar clamping part is a planar structure, which is used to fit the plane of the outer or lower side of the cheek tube.

[0023] Preferably, the clamping ends of the first and second clamping arms are provided with insertion heads, both of which can be used to insert into the bowwire channel, so that either insertion head can be selected for insertion into the bowwire channel during use. The cross-section of the insertion head is rectangular, and the planar clamping part is the two opposite sides of the rectangular insertion head.

[0024] Preferably, the insertion ends of the first and second clamping arms are parallel or perpendicular to each other.

[0025] Preferably, the clamping surface of the planar clamping part is provided with anti-slip texture, which is a grid-like, striped, or dotted protrusion.

[0026] Preferably, the insertion end is provided with a shoulder, which is used to achieve axial positioning.

[0027] Preferably, the end of the insertion tip has a blunted rounded corner structure with a rounded corner radius of 0.2mm-0.5mm.

[0028] Another technical solution of this utility model is: a strip-shaped straight wire bow face tube pliers, including a pliers body, the pliers body being composed of two clamping arms, the two clamping arms being a first clamping arm and a second clamping arm respectively;

[0029] The clamping end of the first clamping arm is provided with an insertion end, the cross-sectional shape of which matches the cross-sectional shape of the archwire channel of the cheek tube, and is used to insert into the archwire channel;

[0030] The clamping end of the second clamping arm is provided with a planar clamping part. The clamping surface of the planar clamping part is a planar structure, which is used to fit the plane of the outer or lower side of the cheek tube.

[0031] Preferably, the clamping ends of the first and second clamping arms are provided with insertion heads, both of which can be used to insert into the bowwire channel, so that either insertion head can be selected for insertion into the bowwire channel during use. The cross-section of the insertion head is rectangular, and the planar clamping part is the two opposite sides of the rectangular insertion head.

[0032] Preferably, the insertion ends of the first and second clamping arms are parallel or perpendicular to each other.

[0033] Preferably, the clamping surface of the planar clamping part is provided with anti-slip texture, which is a grid-like, striped, or dotted protrusion.

[0034] Preferably, the insertion end is provided with a shoulder, which is used to achieve axial positioning.

[0035] Preferably, the end of the insertion tip has a blunted rounded corner structure with a rounded corner radius of 0.2mm-0.5mm.

[0036] The beneficial effects of this utility model are as follows:

[0037] This invention's low-resistance, impact-resistant, straight-wire buccal tube solves the problem of traditional buccal tubes easily detaching due to food impact by combining a flangeless adhesive surface with a streamlined arc-shaped surface and drainage channels. Simultaneously, the integrated design of the planar clamping structure and traction hook improves operational efficiency and patient comfort, making it suitable for various orthodontic treatment needs. This invention achieves a comprehensive improvement in impact resistance, ease of operation, and functional integration through structural optimization.

[0038] This invention's buccal tube forceps or pliers solves the problem of insufficient stability in existing buccal tube gripping techniques. For example, the point contact gripping of the traction hook makes slippage easy; and gripping the outer contour of the buccal tube requires complex structures such as spring clips or anti-slip textures. This invention's strip-shaped straight wire buccal tube forceps or pliers achieves surface contact through geometric adaptation between the insertion end and the archwire channel, combined with the support of planar gripping, significantly reducing the risk of slippage. Furthermore, it eliminates the need to adjust the gripping angle for the traction hook or complex outer contour, directly utilizing the inherent archwire channel and outer planar structure of the buccal tube for gripping.

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0062] like Figure 1 and Figure 2 As shown, a low-resistance, impact-resistant strip-shaped straight wire bow cheek tube includes a cheek tube body 1. The cheek tube body 1 is provided with a bow wire channel 2 that runs through its interior laterally. The bow wire channel 2 is a strip-shaped straight wire bow channel with a vertical rectangular cross-section.

[0063] For ease of description, we first determine the orientation of the structure: the side of the buccal tube 1 facing the tooth 8 is the inner side, the side away from the tooth 8 is the outer side, the side close to the occlusal surface of the tooth 8 is the upper side, and the side close to the gingiva is the lower side.

[0064] The inner surface of the buccal tube 1 is an adhesive surface 3 for fitting the teeth. This means the existing base plate structure of the buccal tube is removed, and the inner surface of the buccal tube 1 is directly processed into the adhesive surface 3, i.e., the mesh bottom, making its structure simpler. The upper edge of the adhesive surface 3 is flush with the corresponding edge of the buccal tube 1, meaning the upper surface of the buccal tube 1 has no outwardly protruding flanges. The upper outer surface of the buccal tube 1 near the occlusal surface of the teeth is a streamlined arc-shaped surface 4, which smoothly transitions downwards from the top of the buccal tube 1. The radius of curvature of the streamlined arc-shaped surface 4 matches the curvature of the occlusal surface of human teeth. The outer surface of the buccal tube 1 is an integral arc-shaped surface from top to bottom. Viewed from the front side (perpendicular to the paper), the outer contour of the buccal tube 1 is crescent-shaped. This design helps reduce the impact surface of the buccal tube, avoiding problems such as adhesive failure or detachment due to direct impact from food during chewing. Example 2

[0065] like Figures 3 to 5As shown, based on Embodiment 1, the outer surface 5 and / or lower surface 6 of the buccal tube 1 are provided with planes that facilitate gripping by tweezers. When the outer surface 5 and lower surface 6 of the buccal tube 1 are provided with planes, the planes of the outer surface 5 and lower surface 6 of the buccal tube 1 are perpendicular to each other, and a chamfer is provided at the junction of the two planes. Example 3

[0066] like Figures 6 to 10 As shown, based on embodiments 1 and 2, the lower part or lower side surface 6 of the cheek tube 1 is provided with a traction hook 7. The root of the traction hook 7 is connected to the lower part or lower side surface 6 of the cheek tube 1, and the main body of the traction hook 7 is located within the outline projection range of the cheek tube 1. Example 4

[0067] like Figures 11 to 18 As shown, based on embodiment 3, at least one drainage ditch 9 is provided on the streamlined arc surface 4 along the vertical direction.

[0068] This invention's low-resistance, impact-resistant, straight-wire buccal tube solves the problem of traditional buccal tubes easily falling off due to food impact by combining a flangeless adhesive surface, an arc-shaped impact-resistant surface, and a drainage groove. At the same time, the planar clamping structure and traction hook integrated design improve operational efficiency and patient comfort, making it suitable for various orthodontic treatment needs. Example 5

[0069] like Figure 19 and Figure 20 As shown, a strip-shaped straight wire buccal tube forceps includes a forceps body 10, which is composed of a first clamping arm 11 and a second clamping arm 12.

[0070] The clamping ends of the first clamping arm 11 and the second clamping arm 12 are both provided with insertion ends 13. The cross-sectional shape of the insertion end 13 matches the cross-sectional shape of the archwire channel 2 of the strip-shaped straight wire buccal tube and is used to insert into the archwire channel 2. Both insertion ends 13 can be used to insert into the archwire channel 2, so that either insertion end can be selected nearby to insert into the archwire channel 2 during use. The cross-section of the insertion end 13 is rectangular and rounded corners are provided around it.

[0071] The insertion ends 13 of the first clamping arm 11 and the second clamping arm 12 are parallel to each other. When the first clamping arm 11 is inserted into the archwire channel 2, the planar clamping part 14 of the insertion end 13 of the second clamping arm 12 adheres to the outer surface 5 of the buccal tube of the strip-shaped straight archwire, thereby realizing clamping by utilizing the inherent archwire channel and outer planar structure of the buccal tube; and vice versa.

[0072] The clamping surface of the planar clamping part 14 is provided with anti-slip texture, which is a grid-like, striped, or dotted protrusion.

[0073] The insertion end 13 is positioned by the shoulder of the insertion end 13, and the end of the insertion end 13 is a blunt rounded corner structure with a rounded corner radius of 0.2mm-0.5mm. Example 6

[0074] like Figure 21 and Figure 22 As shown, a strip-shaped straight wire buccal tube forceps includes a forceps body 10, which is composed of a first clamping arm 11 and a second clamping arm 12.

[0075] The clamping ends of the first clamping arm 11 and the second clamping arm 12 are both provided with insertion ends 13. The cross-sectional shape of the insertion end 13 matches the cross-sectional shape of the archwire channel 2 of the strip-shaped straight wire buccal tube and is used to insert into the archwire channel 2. Both insertion ends 13 can be used to insert into the archwire channel 2, so that either insertion end can be selected nearby to insert into the archwire channel 2 during use. The cross-section of the insertion end 13 is rectangular and rounded corners are provided around it.

[0076] The insertion ends 13 of the first clamping arm 11 and the second clamping arm 12 are perpendicular to each other. When the first clamping arm 11 is inserted into the archwire channel 2, the planar clamping part 14 of the insertion end 13 of the second clamping arm 12 adheres to the lower side surface 6 of the buccal tube of the strip-shaped straight wire archwire, thereby realizing clamping using the inherent archwire channel and outer planar structure of the buccal tube; and vice versa.

[0077] The clamping surface of the planar clamping part 14 is provided with anti-slip texture, which is a grid-like, striped, or dotted protrusion.

[0078] The insertion end 13 is positioned by the shoulder of the insertion end 13, and the end of the insertion end 13 is a blunt rounded corner structure with a rounded corner radius of 0.2mm-0.5mm.

[0079] The above embodiments 5 and 6 are merely illustrative examples using tweezers; this technical solution is also applicable to forceps. For example, a strip-shaped straight wire buccal tube forceps includes a forceps body, wherein the tweezers body is composed of a first clamping arm and a second clamping arm. The remaining technical contents are the same as those in embodiments 5 and 6, and will not be repeated here.

[0080] This invention relates to a strip-shaped straight wire bowstring buccal tube forceps or pliers that solves the problem of insufficient stability in holding buccal tubes in existing technologies. For example, the point contact when gripping the traction hook makes it prone to slippage; and gripping the outer contour of the buccal tube requires complex structures such as spring clips or anti-slip textures. This invention's strip-shaped straight wire bowstring buccal tube forceps or pliers achieves surface contact through geometric adaptation between the insertion end and the bowstring channel, combined with the support of planar gripping, significantly reducing the risk of slippage. Furthermore, it eliminates the need to adjust the gripping angle for the traction hook or complex outer contour, directly utilizing the inherent bowstring channel and outer planar structure of the buccal tube for gripping. Of course, this invention's bowstring buccal tube forceps or pliers are not limited to strip-shaped straight wire bowstring tubes with a strip-shaped straight wire bowstring channel; they are also applicable to other bowstring tubes with bowstring channels and outer planar surfaces.

[0081] The above description is only a part of the embodiments 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 content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
