Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a front traction correction device. Background Art

[0002] The front traction components of traditional front traction correction devices are usually composed of a forehead bracket, a bracket, a positioning block and a mandibular pocket. The forehead bracket is fixed to the forehead, and the mandibular pocket is fixed to the mandibular chin. The two are connected by a bracket, and the positioning block fixed on the bracket is used as the traction fulcrum of the elastic rubber band. It is usually only suitable for the treatment of maxillary traction osteogenesis. The correction components of traditional front traction correction devices generally use the autologous anterior dentition or the periphery of the anterior alveolar area as support. The structure designed for the support must provide a traction fulcrum for the elastic rubber band. The traction force passes through the anterior dentition or the periphery, and then transmits the traction force to the mandible and the maxillary peripheral bone suture to achieve the purpose of traction osteogenesis.

[0003] At present, traditional anchorages mainly include anchorages fixed by matching the dentition or anchorages implanted around the alveolar area. These anchorages have certain therapeutic effects in some simple cases, but there are still the following problems: Since the anchorage structure around the fixed alveolar area is complex and generally has hooks, it not only affects the aesthetics, but also greatly reduces the patient's comfort in the mouth; for patients whose teeth are in the development stage or whose dentition is not strong, the effect of the anterior traction force may only lead to the forward movement of the dentition, while the traction force that should act on the jaw is lost, which greatly weakens the treatment effect; for patients with a tendency to crossbite, there will be unreasonable anterior traction force directions that will further increase the patient's tendency to open the jaw. Similarly, there will be unreasonable anterior traction directions that will increase the patient's tendency to crossbite. Summary of the invention

[0020] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] It should be understood that the present invention uses the terms "front", "back", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, "front" information may also be referred to as "back" information, and "back" information may also be referred to as "front" information without departing from the scope of the present invention.

[0022] like Figures 1 to 4 As shown, an embodiment of the present invention provides a front traction correction device, which includes a front traction component 1, a correction component 2 and a traction rope 4. Specifically, the front traction component 1 includes a nose bridge 11 and a first temple 12 and a second temple 13 connected to the nose bridge 11. The first temple 12 and the second temple 13 have the same structure and are respectively arranged at the left and right ends of the nose bridge 11. A mounting platform is extended on the side of the nose bridge 11 facing away from the patient. The mounting platform is provided with a plurality of adjustment holes arranged side by side. A traction adjustment rod 18 connected to the traction frame is passed through the adjustment hole. A horizontally arranged traction bracket 19 is connected to the traction adjustment rod 18. The traction bracket 19 is provided with a traction pin 191. The correction component 2 includes a fixing plate 21 fixed in the patient's mouth and a traction plate 22 connected to the fixing plate 21. The two ends of the traction rope 4 are respectively sleeved on the traction pin 191 and the traction plate 22.

[0023] Based on the above structure, before implementing traction correction, a fixing plate 21 is surgically set on both sides of the alveolar ridge area of ​​the patient, and then the traction plate 22 is installed in the fixing plate 21, and a traction rope 4 with appropriate elasticity is selected to hang the two ends of the traction rope 4 on the traction nail 191 of the front traction component 1 and the hook-shaped traction section 222 of the traction plate 22, respectively. During the traction process, the traction force on both sides is maintained at about 400-500g, and the traction time is maintained for more than 12 hours a day. The traction correction of the crossbite can be achieved. In this way, the front traction correction device has a simple structure, convenient installation, simple operation, and good stability during use. The structure of the front traction component 1 is similar to glasses. It is easy to use and comfortable to wear. The adjustable headband 3 can adjust the tightness at any time to enhance the user's wearing experience. The traction adjustment rod 18 and the traction bracket 19 are quick to install and easy to adjust, and the use process is stable and reliable. The entire front traction component 1 can be used for Angle Class II malocclusion with the position of the mandibular first molar retracted and the maxilla normally developed, and can also be used for Angle Class III malocclusion with the position of the maxillary first molar retracted and the mandibular normally developed. It has many application scenarios and good treatment effects. The fixing plate 21 and the traction plate 22 of the correction component 2 are implanted under the oral mucosa. When not in use, the patient has almost no foreign body sensation. The fixing plate 21 is fixed in the maxillary bone and is not affected by the patient's dentition. The various components of the correction component 2 are processed and prepared using metal 3D printing technology. The matching implants designed for patients can greatly compress the space occupied by the implants and enhance the patient's use experience.

[0024] Optionally, in order to further enhance the patient's wearing experience, in some embodiments of the present application, a fork rod is provided on the nose frame 11, and an inverted V-shaped silicone nose pad 111 is provided on the fork rod. The nose pad 111 fits well with the patient's nose and is highly comfortable to wear.

[0025] Furthermore, the mounting platform of the present application may have a variety of forms. Specifically, in order to enhance the connection strength between the traction adjustment rod 18 and the mounting platform, in an embodiment of the present invention, the mounting platform includes an upper boss 15 and a lower boss 16, and the adjustment hole includes a top hole provided on the upper boss 15 and a bottom hole 161 provided on the lower boss 16. Meanwhile, in order to achieve effective fixation of the traction adjustment rod 18 and the mounting platform, the traction adjustment rod 18 is arranged in a T-shape, and the upper boss 15 is provided with a T-shaped square groove 151 matching the traction adjustment rod 18. The traction adjustment rod 18 passes through the top hole and the bottom hole 161 and is inserted into the T-shaped square groove 151 to achieve a fixed connection with the upper boss 15. Furthermore, in order to prevent the traction adjustment rod 18 from being ejected from the T-shaped square groove 151, a top cover 17 is provided on the top of the T-shaped square groove 151. The top cover 17 can limit the traction adjustment rod 18, thereby further strengthening the reliable connection between the traction adjustment rod 18 and the upper boss 15. For the top cover 17 of the present application, it can effectively improve the connection effect between the top cover 17 and the upper boss 15 by hooking it into the groove beside the T-shaped square groove 151, thereby ensuring the limiting effect on the traction adjustment rod 18.

[0026] The upper end of the traction adjustment rod 18 matches with the T-shaped square groove of the upper boss 15 and the square groove of the lower boss 16 of the nose frame 11 in turn, and the top cover 17 limits the traction adjustment rod 18. The lower end of the traction adjustment rod 18 matches with the square groove of the traction bracket 19, and the two are fixedly connected by the connecting nail 192. The traction adjustment rod 18 is a T-shaped square rod, which matches with the T-shaped square groove of the upper mounting platform of the nose frame 11. The rod section about 3 cm away from the upper end of the traction adjustment rod 18 matches with the square groove of the lower mounting platform, which greatly reduces the deflection of the lower end of the traction adjustment rod 18 due to the traction force. Anti-skid grooves are provided on the front and rear sides of the lower end of the traction adjustment rod 18 to increase the friction with the connecting nail 192, so that the traction bracket 19 is firmly connected to the traction adjustment rod 18 under the tightening action of the connecting nail 192. The upper boss 15 and the lower boss 16 are provided with five T-shaped square slots and five square slots in the front and rear directions respectively, wherein the distance between the frontmost slot hole and the rearmost slot hole is 2.5 cm, and the traction adjustment rod 18 realizes the front and rear adjustment function by inserting different slot holes.

[0027] The traction bracket 19 is a curved square rod, and a connecting hole is provided on the front side of the middle section of the traction bracket 19 for setting a connecting nail 192. A square groove is provided on the upper side of the middle section of the traction bracket 19, which is matched and connected with the traction adjustment rod 18. A number of screw holes are provided on the upper sides of the left and right sides of the traction bracket 19 for fixing the traction nail 191. The traction bracket 19 adopts the structure of a curved square rod. According to the 2 cm width of the front and rear sides of the traction bracket 19, the front and rear sides of the traction bracket 19 are swapped and fixed, which can increase the adjustment range of the traction bracket 19 by 4 cm. The adjustment range of the traction adjustment rod 18 is superimposed, so the adjustment range of the traction bracket 19 is 6.5 cm front and back. The traction bracket 19 slides up and down on the anti-slip groove of the traction adjustment rod 18 to ensure that the traction bracket 19 can be aligned with the oral position of different patients through up and down adjustment.

[0028] The traction nail 191 is a common hexagon socket screw, and the cylindrical nut of the traction nail 191 is used as a traction support point to hook the traction rope 4. The traction nail 191 can be fixed at different hole positions on the left and right sides of the traction bracket 19. Using the traction nails 191 at different hole positions as traction points can achieve the purpose of changing the traction direction.

[0029] In addition, for the first temple 12 and the second temple 13 of the present application, the two have the same structure, and are both hingedly connected to the nose bridge 11 through the hinge 14. At the same time, the first temple 12 and the second temple 13 are both telescopic rod structures. Taking the first temple 12 as an example, it includes a forearm 121 and a telescopic rear arm 122 arranged in the forearm 121. The forearm 121 is hingedly connected to the nose bridge 11, and the end of the rear arm 122 is provided with an adjustable headband 3 through a threading hole 123. The adjustable headband 3 passes through the two threading holes 123 to connect the first temple 12 and the second temple 13. When the patient wears the front traction assembly 1, the patient can also change the tightness of the adjustable headband 3 to the patient's head by adjusting the sleeve on the adjustable headband 3, which is flexible to adjust and easy to use.

[0030] Optionally, in some embodiments of the present application, the fixing plate 21 is provided with a screw hole, and the fixing plate 21 is fixedly connected to the patient's bone tissue by a fastening nail 211. The fixing plate 21 is also provided with a connecting groove 212. The traction plate 22 has a V-shaped connecting section 221 and a hook-shaped traction section 222. The V-shaped connecting section 221 has a certain elastic deformation ability due to the plate thickness design. The hook-shaped traction section 222 is used to fix the traction rope 4. An inner clamping protrusion 213 is provided in the connecting groove 212, and the V-shaped connecting section 221 is provided with an outer clamping protrusion 223 matched therewith. The one-way limiting of the V-shaped connecting section 221 is achieved by the inner clamping protrusion 213 and the outer clamping protrusion 223. The V-shaped connecting section 221 is inserted into the connecting groove 212 to realize the connection between the traction plate 22 and the fixing plate 21. The fixing plate 21, the fastening nail 211 and the traction plate 22 are all made of titanium alloy, which has good compatibility with the human body and good patient experience.

[0031] The traction rope 4 of the present application is usually symmetrically fixed on both sides of the traction adjustment rod 18, and each traction rope 4 is clamped at the traction nail 191 and the hook-shaped traction section 222 of the traction plate 22. The traction force generated by the traction rope 4 on the jawbone is changed by adjusting the traction adjustment rod 18 and the traction bracket 19 to change the spatial position of the traction point or replacing different traction ropes 4, and the traction direction of the elastic rubber band is changed by adjusting the traction bracket 19, the traction nail 191 and the fixing plate 21.
