DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1-10 The present embodiment provides an adjustable brace, comprising a maxillary brace 1, a mandibular brace 3 and a connecting member 2, wherein the connecting member 2 comprises a first connecting portion 21 arranged on the side of the maxillary brace 1 opposite to the mandibular brace 3, a second connecting portion 22 arranged on the side of the mandibular brace 3 opposite to the maxillary brace 1, and a rotating portion 23 connected to both ends of the first connecting portion 21 and both ends of the second connecting portion 22, wherein the first connecting portion 21 and the second connecting portion 22 are connected in an opening and closing manner through the rotating portion 23 to drive the maxillary brace 1 and the mandibular brace 3 to perform an opening and closing action.

[0020] It can be understood that the maxillary braces 1 in this embodiment are used to be inserted into the maxillary teeth, the mandibular braces 3 are used to be inserted into the mandibular teeth, and the connecting member 2 is used to connect the maxillary braces 1 and the mandibular braces 3. It should be explained that the first connecting portion 21 is attached to the side of the maxillary braces 1 relative to the mandibular braces 3, that is, the first connecting portion 21 is connected to the occlusal side of the maxillary braces 1, and the shape of the first connecting portion 21 is also similar to the shape of the occlusal side of the maxillary braces 1; the second connecting portion 22 is attached to the side of the mandibular braces 3 relative to the maxillary braces 1, that is, the second connecting portion 22 is connected to the occlusal side of the mandibular braces 3, and the shape of the second connecting portion 22 is also similar to the shape of the occlusal side of the mandibular braces 3.

[0021] Among them, a first matching groove 211 is provided on the first connecting part 21, a first matching piece 122 is provided on the maxillary braces 1, a first clamping portion is provided in the first matching groove 211 along the front-to-back direction of the maxillary braces 1, the first matching piece 122 is installed in the first matching groove 211 and can be selectively clamped in any clamping position of the first clamping portion, so that the maxillary braces 1 is connected to the first connecting part 21 and can be selectively moved to the front or rear side of the first connecting part 21; a second matching groove is provided on the second connecting part 22, a second matching piece is provided on the mandibular braces 3, and a plurality of second clamping portions are provided in the second matching groove along the front-to-back direction of the mandibular braces 3, the second matching piece is installed in the second matching groove and can be selectively clamped in any clamping position of the second clamping portion, so that the mandibular braces 3 is connected to the second connecting part 22 and can be selectively moved to the front or rear side of the second connecting part 22.

[0022] It can be understood that the first matching groove 211 and the second matching groove are respectively provided in the first connecting portion 21 and the second connecting portion 22, and the first clamping portion is provided in the first matching groove 211 along the front-to-back direction, and the second clamping portion is provided in the second matching groove along the front-to-back direction. The first matching piece 122 and the second matching piece on the maxillary braces 1 and the mandibular braces 3 can be installed in the first matching groove 211 and the second matching groove, and selectable clamping fixation can be achieved through the first clamping portion and the second clamping portion. Since the first clamping portion and the second clamping portion are provided along the front-to-back direction, the first matching piece 122 and the second matching piece can be moved between different clamping positions of the first clamping portion and the second clamping portion respectively, thereby realizing the front-to-back adjustment of the maxillary braces 1 and the mandibular braces 3 on the first connecting portion 21 and the second connecting portion 22, and then realizing the adjustment of the relative position relationship between the patient's maxillary teeth and mandibular teeth.

[0023] In some embodiments, the connecting member 2 is of an integrated design, and the rotating portion 23 is a flexible structure connected between the first connecting portion 21 and the second connecting portion 22. It can be understood that the integrated design means that the connecting member 2 is manufactured as a whole, avoiding assembly gaps and looseness problems between multiple parts, and the rotating portion 23 of the flexible structure utilizes the elastic deformation ability of the material to enable the first connecting portion 21 and the second connecting portion 22 to rotate relative to each other, thereby adapting to different movement states of the oral cavity.

[0024] Furthermore, the maxillary braces 1 include an upper brace 11 and an upper bearing plate 12 disposed on the side of the upper brace 11 facing the mandibular brace 3, the first matching piece 122 is disposed on the side of the upper bearing plate 12 facing the mandibular brace 3, a plurality of first clamping holes 121 are disposed on the side of the upper bearing plate 12 facing the upper brace 11, and a plurality of first protrusions 111 are disposed on the side of the upper brace 11 facing the upper bearing plate 12, and the plurality of first clamping holes 121 are correspondingly connected with the plurality of first protrusions 111 one by one, so that the upper brace 11 and the upper The bearing plate 12 is relatively fixed; the mandibular braces 3 include a lower braces 31 and a lower bearing plate 32 disposed on the side of the lower braces 31 facing the maxillary braces 1, the second matching piece is disposed on the side of the lower bearing plate 32 facing the maxillary braces 1, a plurality of second clamping holes are disposed on the side of the lower bearing plate 32 facing the lower braces 31, a plurality of second protrusions are disposed on the side of the lower braces 31 facing the lower bearing plate 32, and the plurality of second clamping holes are correspondingly engaged with the plurality of second protrusions one by one, so that the lower braces 31 and the lower bearing plate 32 are relatively fixed. Preferably, the plurality of first clamping holes 121 are evenly arranged on the side of the upper bearing plate 12 facing the upper braces 11, and the plurality of second clamping holes are evenly arranged on the side of the lower bearing plate 32 facing the maxillary braces 1.

[0025] It is understandable that by designing the maxillary brace 1 to include two parts, the upper brace 11 and the upper bearing plate 12, and designing the mandibular brace 3 to include two parts, the lower brace 31 and the lower bearing plate 32, the brace can be made easier to clean, maintain and replace while maintaining the correction function. In addition, by respectively providing the first clamping hole 121 and the second clamping hole on the upper bearing plate 12 and the lower bearing plate 32, and respectively providing the corresponding first protrusion 111 and the second protrusion on the upper brace 11 and the lower brace 31, a firm clamping connection between the brace components can be achieved, thereby improving the overall stability and durability of the brace. During assembly, firstly place the upper bearing plate 12 in an appropriate position, then align the first protrusion on the upper brace 11 with the first clamping hole 121 on the upper bearing plate 12, and press hard to make the first protrusion 111 clamp into the first clamping hole 121, thereby achieving a firm clamping connection between the upper brace 11 and the upper bearing plate 12, and the assembly process of the lower bearing plate 32 and the lower brace 31 is similar, which will not be repeated here. During disassembly, the first protrusion 111 / the second protrusion can be disengaged from the first clamping hole 121 / the second clamping hole by applying appropriate external force, thereby realizing the disassembly of the maxillary braces 1 / the mandibular braces 3. This design allows the braces to be easily disassembled and reassembled when they need to be cleaned, maintained or replaced.

[0026] In some embodiments, the upper braces 11 and the lower braces 31 are made of elastic EVA material. It is understandable that EVA (ethylene-vinyl acetate copolymer) material has good elasticity, softness and biocompatibility. The upper braces 11 and the lower braces 31 are made of elastic EVA material, which can make the braces fit the patient's teeth and oral shape better, reduce discomfort, and adapt to the slight movement of the teeth during the correction process, thereby improving the correction effect.

[0027] The structural relationship between the upper brace 11, the upper bearing plate 12 and the first connecting portion 21 is explained below: In this embodiment, a plurality of first serrated protrusions 2111 are arranged on the groove wall of the first matching groove 211 facing the labial direction of the upper brace 11 along the front-back direction of the maxillary brace 1, and the first clamping portion includes the first serrated protrusion 2111; a first serrated groove 1221 corresponding to the first serrated protrusion 2111 is arranged on the side wall of the first matching piece 122 facing the labial direction of the upper brace 11; the upper bearing plate 12 is made of elastic material, and the upper bearing plate 12 is assembled on the first connecting portion 21 in a bent and compressed state, so that the upper bearing plate 12 always has an elastic force on the first connecting portion 21 to straighten in the opposite direction of its bending direction, and the first matching piece 122 always has an elastic force close to the groove wall on one side of the first serrated protrusion 2111 in the first matching groove 211. It should be explained that in this embodiment, the side facing the lip and cheek mucosa is called the labial side, and the side facing the tongue is called the lingual side.

[0028] It can be understood that when installing the first mating piece 122, the user needs to apply a certain external force to push the first mating piece 122 into the first mating groove 211, and align the first serrated groove 1221 with any first serrated protrusion 2111 in the first mating groove 211. During this process, the upper supporting plate 12 will bend and deform until the first serrated groove 1221 is fully engaged with the selected first serrated protrusion 2111. At this time, due to the elastic restoring force of the upper supporting plate 12, it will apply an elastic force to the groove wall on one side of the first serrated protrusion 2111 on the first mating piece 122. This elastic force makes the first serrated protrusion 2111 and the first serrated groove 1221 tightly engage with each other, ensuring the first mating piece 122 in the first mating groove 211. The stable installation, and then ensuring the stable installation of the upper supporting plate 12 and the first connecting portion 21, and then ensuring the stable installation of the maxillary braces 1 and the first connecting portion 21.

[0029] Furthermore, the adjustable braces also include a first adjustment device, which includes a first reel 123 arranged at the lingual tooth midline of the upper bearing plate 12, and a first tensioning wire 124 wound around the first reel 123, and both ends of the first tensioning wire 124 are connected to the left and right sides of the upper bearing plate 12. When the first reel 123 winds or releases the first tensioning wire 124, the upper bearing plate 12 is compressed in the bending direction or released in the opposite direction of the bending direction by the tension. Therefore, when the user needs to adjust the front-to-back relationship of the maxillary braces 1 relative to the first connecting portion 21, the first tension rope can be wound by the first reel 123, and the first tension rope will apply a central pulling force to both sides of the upper bearing plate 12, so that the upper bearing plate 12 is bent in a direction with a larger bending angle, so that the first serrated groove 1221 of the first matching piece 122 provided on the upper bearing plate 12 is separated from the first serrated protrusion 2111 in the first matching groove 211. At this time, it is only necessary to drag the upper bearing plate 12 or the first connecting portion 21. The part 21 can change the front-to-back position relationship of the maxillary braces 1 relative to the connecting member 2, and further change the front-to-back position relationship of the maxillary braces 1 relative to the mandibular braces 3. After the above-mentioned front-to-back position relationship is adjusted, the first tension rope is released by the first reel 123, and the elastic force of the upper bearing plate 12 can be released, so that the first serrated groove 1221 of the first matching member 122 provided on the upper bearing plate 12 is tightly matched with the corresponding first serrated groove in the first matching groove 211, so that the upper bearing plate 12 is fixed to the first connecting part 21.

[0030] In this embodiment, by introducing the first adjustment device, the user can conveniently adjust the position of the maxillary braces 1 according to personal needs or the correction process without completely disassembling or reinstalling the braces. Specifically, the first reel 123 acts as an adjustment mechanism, and changes the tension on the upper bearing plate 12 by winding or releasing the first tension line 124. When the first reel 123 winds the first tension line 124, the upper bearing plate 12 is subjected to a central tension force, causing it to be further compressed in the bending direction; when the first reel 123 releases the first tension line 124, the upper bearing plate 12 is released in the opposite direction of the bending direction under the action of the elastic force.

[0031] Specifically, the first cable reel 123 is a manual cable reel or an electric cable reel. The manual cable reel is provided with a knob for controlling the winding or releasing of the first tensioning line 124. The electric cable reel is provided with a micro motor and a Bluetooth module for controlling the winding or releasing of the first tensioning line 124. The Bluetooth module is used to connect to the smart device via Bluetooth and control the operation of the micro motor. It is understandable that when the first cable reel 123 is a manual cable reel, the user can hold the knob and rotate it clockwise or counterclockwise as needed. The rotation of the knob will drive the internal winding mechanism to work, realize the winding or releasing of the first tensioning line 124, and when the desired position is reached, the user stops rotating the knob and the cable reel stops working. When the first wire reel 123 is an electric wire reel, the user can send a control instruction through a smart device (such as a mobile phone APP). After receiving the instruction, the Bluetooth module passes it to the control circuit. The control circuit controls the working direction and speed of the micromotor according to the instruction. The micromotor drives the winding mechanism to work to achieve the winding or release of the first tensioning wire 124. When the desired position is reached, the user sends a stop instruction through the smart device, and the control circuit controls the micromotor to stop working. It should be explained that both manual and electric wire reels provide users with convenient operation methods. Manual wire reels are directly controlled by knobs, which is simple and intuitive; electric wire reels are remotely controlled by smart devices, which is more efficient and convenient.

[0032] Furthermore, a first deformation notch 212 is provided on the middle lip side of the first connection portion 21. When the first connection portion 21 is bent or straightened in the direction from the tongue side to the labial side, the first deformation notch 212 is correspondingly deformed to adapt to the state of the first connection portion 21. It can be understood that by providing the first deformation notch 212 on the middle lip side of the first connection portion 21, it is allowed to be deformed accordingly when it is bent or straightened in the direction from the tongue side to the labial side, thereby avoiding excessive stress concentration and material fatigue, which can not only improve the service life of the first connection portion 21, but also ensure that it maintains stable performance during frequent adjustments.

[0033] Further, in order to enhance the connection stability and reliability between the upper bearing plate 12 and the first connecting portion 21, the upper bearing plate 12 is provided with a first barb 125 at the portion of the first deformation notch 212, and the first connecting portion 21 is provided with a hook-shaped first clamping block 213 corresponding to the first barb 125, and the first barb 125 is hooked on the first clamping block 213. It can be understood that the cooperation between the first barb 125 and the first clamping block 213 is similar to a lock structure, and the connection between the two components is ensured to be stable by hooking and locking. When the first barb 125 is hooked on the first clamping block 213, a firm connection point is formed between them, which can resist pulling or pushing forces from all directions, thereby ensuring a stable connection between the upper bearing plate 12 and the first connecting portion 21, and preventing the possibility of accidental falling off or movement.

[0034] Furthermore, a plurality of first deformation grooves 126 are provided on the middle tongue side of the upper bearing plate 12. When the upper bearing plate 12 is bent or straightened in the direction from the tongue side to the labial side, the first deformation grooves 126 are correspondingly deformed to adapt to the state of the upper bearing plate 12. It can be understood that, in this embodiment, a plurality of first deformation grooves 126 are provided on the middle tongue side of the upper bearing plate 12, so that it is allowed to deform correspondingly when subjected to external force, thereby dispersing stress and reducing material fatigue, which not only helps to maintain the overall strength and stability of the upper bearing plate 12, but also prolongs its service life during frequent adjustments, while improving user experience.

[0035] The structural relationship between the lower brace 31, the lower bearing plate 32 and the second connecting portion 22 is explained below: In this embodiment, a plurality of second serrated protrusions are arranged on the groove wall of the second matching groove facing the labial direction of the lower brace 31 along the front-back direction of the mandibular brace 3, and the second clamping portion includes a second serrated protrusion; a second serrated groove corresponding to the second serrated protrusion is arranged on the side wall of the second matching piece facing the labial direction of the lower brace 31; the lower bearing plate 32 is made of elastic material, and the lower bearing plate 32 is assembled on the second connecting portion 22 in a bent and compressed state, so that the lower bearing plate 32 always has an elastic force on the second connecting portion 22 to straighten in the opposite direction of its bending direction, and the second matching piece always has an elastic force close to the groove wall on one side of the second serrated protrusion in the second matching groove. Among them, the matching relationship between the second matching groove and the second matching piece is similar to the matching relationship between the first matching groove 211 and the first matching piece 122, and will not be repeated here.

[0036] Furthermore, the adjustable braces also include a second adjustment device, which includes a second reel disposed at the lingual tooth midline of the lower bearing plate 32, and a second tensioning wire wound on the second reel, and the two ends of the second tensioning wire are connected to the left and right sides of the lower bearing plate 32. When the second reel winds or releases the second tensioning wire, the lower bearing plate 32 is compressed in the bending direction or released in the opposite direction of the bending direction by the tension. The working principle of the second adjustment device is the same as that of the first adjustment device, which will not be described in detail here.

[0037] Specifically, the second cable reel is a manual cable reel or an electric cable reel. The manual cable reel is provided with a knob for controlling the winding or releasing of the second tensioning wire. The electric cable reel is provided with a micromotor and a Bluetooth module for controlling the winding or releasing of the second tensioning wire. The Bluetooth module is used to connect to the smart device via Bluetooth and control the operation of the micromotor.

[0038] Furthermore, a second deformation notch is provided at the middle lip side of the second connection portion 22. When the second connection portion 22 is bent or straightened in the direction from the tongue side to the lip side, the second deformation notch is correspondingly deformed to adapt to the state of the second connection portion 22. The working principle of the second deformation notch is the same as that of the first deformation notch 212, which will not be described in detail here.

[0039] Furthermore, the lower bearing plate 32 is provided with a second barb at the second deformation notch, and the second connecting portion 22 is provided with a hook-shaped second clamping block corresponding to the second barb, and the second barb is hooked on the second clamping block. The matching relationship between the second barb and the second clamping block is the same as the matching relationship between the first barb 125 and the first clamping block 213, which will not be described in detail.

[0040] Furthermore, a plurality of second deformation grooves are provided on the middle tongue side of the lower bearing plate 32. When the lower bearing plate 32 is bent or straightened in the direction from the tongue side to the labial side, the second deformation grooves are correspondingly deformed to adapt to the state of the lower bearing plate 32. The working principle of the second deformation groove is the same as that of the first deformation groove 126, which will not be described in detail here.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
