Description

Technical Field

[0001] This utility model relates to the field of orthodontics, and mainly to a chest brace type orthodontic traction device. Background Technology

[0002] Orthodontics generally refers to the treatment of abnormal tooth alignment, imbalances between dental arches and jaws, and imbalances between the dentition and craniofacial region using various orthodontic techniques. The therapeutic effect is achieved through the corrective and shaping forces generated by various orthodontic appliances. These shaping forces primarily act on the skull and jawbone, altering certain bone morphologies and opening sutures.

[0003] Orthodontic appliances are devices that generate corrective force. Anterior traction devices, specifically sagittal traction devices, are used to treat skeletal Class III malocclusion caused by maxillary hypoplasia and to improve midface retraction. Because the corrective force is substantial and originates from outside the mouth, stable wearing of the appliance is crucial for its effectiveness.

[0004] Current anterior traction devices, such as the one disclosed in patent CN221534117U, are oral orthodontic traction devices. These devices are only slightly improved versions of the headband-style traction device. However, the lower end of this type of headband-style traction device still applies force near the jaw and then transmits the force to the face. The correction process can also cause harm to the user, especially since most users are children whose bones are not yet fully formed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a chest support type orthodontic traction device.

[0006] A chest-support type orthodontic traction device includes an arc-shaped rod, the lower end of which is connected to a chest support for supporting the chest, and the upper end of which is connected to a forehead support for supporting the forehead. It also includes a first sliding part mounted on the arc-shaped rod and slidably connected along the arc-shaped rod, with the forehead support mounted on the first sliding part. Furthermore, it includes an adjustment structure for adjusting the distance between the forehead support and the arc-shaped rod, with the forehead support connected to the first sliding part through the adjustment structure.

[0007] Preferably, the adjustment structure includes a mating groove, a plug-in post inserted into the mating groove, and a locking member that locks the plug-in post to the mating groove; the mating groove is designed on the forehead support portion, and the plug-in portion is fixedly connected to the first sliding portion.

[0008] Preferably, a locking hole is provided on the top wall of the mating groove, and the locking element is a locking screw. The locking element passes through the locking hole and is fixedly connected to the plug-in post or abuts against the plug-in post.

[0009] Preferably, the plug is provided with a fixing hole groove corresponding to the locking member, and the number of fixing holes can be multiple or strip-shaped.

[0010] Preferably, the device also includes a connecting rod and a second sliding part for connecting the orthodontic components, the second sliding part being slidably mounted on the arc-shaped rod; the first sliding part and the second sliding part are mounted on the connecting rod.

[0011] Preferably, the first sliding part and the second sliding part are fixed to the connecting rod by fixing screws.

[0012] Preferably, the lower end of the arc-shaped rod is a spherical structure, and a spherical groove is provided on the chest support part. The lower end of the arc-shaped rod forms a ball joint structure by cooperating with the spherical groove through the spherical structure.

[0013] Compared with existing technologies, this solution has the following advantages: The lower end of the traction device is supported in front of the chest, and due to the large force-bearing area, it will not affect the user's bones. Secondly, to accommodate different users' facial parameters, this solution can be adjusted to ensure that the distance between the upper end of the arc-shaped rod and the correction end meets the requirements.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] Example 1

[0019] A chest-support type orthodontic traction device includes an arc-shaped rod 1, with a chest support 2 connected to the lower end of the arc-shaped rod 1 for supporting the chest and a forehead support 3 for supporting the forehead at the upper end. It also includes a first sliding part 4 mounted on the arc-shaped rod 1 and slidably connected along the arc-shaped rod 1, with the forehead support 3 mounted on the first sliding part 4. Furthermore, it includes an adjustment structure 5 for adjusting the distance between the forehead support 3 and the arc-shaped rod 1, with the forehead support 3 connected to the first sliding part 4 via the adjustment structure 5. The arc-shaped rod 1 is located in front of the face, specifically along the midline of the bridge of the nose, with its lower end extending to the chest and fixed by the chest support 2, and its upper end fixed to the head via the forehead support 3. To avoid restricting head movement, the lower end of the support rod and the chest support 2 are obviously structures that can rotate relatively freely.

[0020] In this embodiment, the adjustment structure 5 includes a mating groove 6, a plug-in post 7 inserted into the mating groove 6, and a locking member 8 that locks the plug-in post 7 to the mating groove 6; the mating groove 6 is designed on the forehead support part 3, and the plug-in part is fixedly connected to the first sliding part 4. The purpose of this structure is to adjust the distance between the forehead support part 3 and the arc-shaped rod 1, thereby matching the needs of different people.

[0021] In this embodiment, a locking hole 9 is provided on the top wall of the mating groove 6, and the locking member 8 is a locking screw. The locking member 8 passes through the locking hole 9 and is fixedly connected to or abutted against the plug-in post 7. After the distance is adjusted, the locking member 8 is fixedly connected to the plug-in post 7 in this embodiment.

[0022] In this embodiment, the plug-in post 7 is provided with fixing slots 10 corresponding to the locking member 8. The number of fixing slots 10 can be multiple or strip-shaped. Specifically, in this solution, the plug-in post 7 is provided with multiple fixing slots 10, which can satisfy the need to adjust the extension distance of the plug-in post 7, thereby achieving the function of adjusting the distance between the forehead support part 3 and the arc-shaped rod 1.

[0023] The device also includes a connecting rod 14 and a second sliding part 11 for connecting oral orthodontic components. The second sliding part 11 is slidably mounted on the arc-shaped rod 1. The first sliding part 4 and the second sliding part 11 are mounted on the connecting rod 14.

[0024] The first sliding part 4 and the second sliding part 11 are fixed to the connecting rod 14 by fixing screws 12. The fixing screws 12 can adjust the initial distance between the first sliding part 4 and the second sliding part 11, thereby matching the distance from the forehead to the mouth of different users.

[0025] In order not to affect head movements, such as turning the head, raising the head, and lowering the head, the lower end of the arc-shaped rod 1 is a spherical structure 13, and a spherical groove 15 is provided on the chest support part 2. The lower end of the arc-shaped rod 1 forms a ball joint structure by cooperating with the spherical structure 13 and the spherical groove 15.

[0026] In this design, the lower end of the traction device is supported in front of the chest. Due to the large force-bearing area, it will not affect the user's bones. Secondly, to accommodate different users' facial parameters, this design can be adjusted to ensure that the distance between the upper end of the arc-shaped rod 1 and the correction end meets the requirements.
