Description

Technical Field

[0001] This utility model relates to the field of orthodontics, and in particular to an adjustable external traction device for impacted teeth. Background Technology

[0002] In the field of orthodontic treatment, impacted teeth, as a common dental developmental abnormality, bring many challenges to clinical treatment. Impacted teeth refer to the phenomenon that teeth fail to erupt normally during development and instead remain in the jawbone.

[0003] The invention discloses a device, method, and system for assisting in the traction of impacted teeth in the oral and maxillofacial region, as disclosed in publication number CN 115553947 A. The device includes a traction unit and a fixing unit. The invention obtains the impaction location of the impacted tooth, determines the traction path of the impacted tooth based on its target position in orthodontic treatment, sets a traction point on the external oral and maxillofacial region based on the impaction location and traction path, and connects it to the traction buckle of the impacted tooth via an elastic connector. According to the target position, traction force is continuously applied through the elastic connector to pull the impacted tooth to the target position according to the traction path. However, the position and direction of impacted teeth vary, and the optimal traction point may differ significantly between different patients and even between different impacted teeth of the same patient. Since the position of the traction buckle within the traction device is usually relatively fixed and difficult to adjust according to the patient's specific situation, it may be impossible to accurately apply the traction force to the ideal traction point during actual treatment, thus affecting the traction effect.

[0004] Therefore, it is necessary to design an adjustable external traction device for impacted teeth that can move the traction block up and down, left and right, and forward and backward according to the requirements, so as to facilitate flexible adjustment of the traction point. Summary of the Invention

[0005] To overcome the shortcomings of existing impacted tooth traction devices, which typically have relatively fixed traction buckles that are difficult to adjust according to the patient's specific situation, thus potentially affecting the traction effect by not being able to accurately apply traction force to the most ideal traction point during actual treatment, this invention provides an adjustable external traction device for impacted teeth that allows for up-down, left-right, and forward-backward movement of the traction block as needed, facilitating flexible adjustment of the traction point.

[0006] The technical solution of this utility model is as follows: an adjustable external traction device for impacted teeth, comprising an elastic band, pull rings, a strap, a soft pad, a buckle, a buccal support frame, a support sleeve, and an adjustment component. The elastic band is provided on the left and right sides, and a pull ring is connected to the front of each elastic band. A strap is connected between the pull rings. A soft pad is connected to the rear side of the strap. A buckle is provided between the rear sides of the elastic band. A buccal support frame is connected to the lower side of the soft pad. A support sleeve is rotatably connected to the lower part of the buccal support frame. An adjustment component is provided on the buccal support frame to adjust the traction point as needed.

[0007] In one embodiment, both the left and right sides of the strap are made of elastic material.

[0008] In one embodiment, the cushion has multiple ventilation holes.

[0009] In one embodiment, the support sleeve has an elliptical structure.

[0010] In one embodiment, the adjustment assembly includes a sliding sleeve, an adjusting rod, a traction block, a screw, and a limiting block. The left and right sides of the cheek support frame are slidably connected to the sliding sleeves, and the adjusting rod is slidably connected between the sliding sleeves. The middle of the adjusting rod is slidably connected to the left and right traction blocks. The traction blocks and the sliding sleeves are both threadedly connected to the screws, and the sliding sleeves and the traction blocks are both slidably connected to the limiting blocks. The limiting blocks are rotatably connected to their adjacent screws, and the cheek support frame and the adjusting rod are engaged with their adjacent limiting blocks.

[0011] In one embodiment, the screw is equipped with a knob.

[0012] Beneficial effects: 1. This utility model adjusts the height of the traction block by moving the adjusting rod up and down, then adjusts the distance between the traction block and the user's lips by moving the adjusting rod back and forth, and finally adjusts the traction block left and right by moving the adjusting rod. This achieves the effect of being able to adjust the traction block up and down, left and right, and back and forth according to needs, which facilitates flexible adjustment of the traction point.

[0013] 2. This utility model uses a soft pad to contact and fit the user's forehead, and then uses a buckle to fix the device to the user's head. Both sides of the strap are made of elastic material, which can achieve a fit and fixation through the cooperation of the elastic band, strap and soft pad, avoiding displacement caused by insufficient fit in some areas.

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] An adjustable external traction device for impacted teeth, such as Figures 1-3 As shown, it includes an elastic band 1, pull rings 2, a strap 3, a soft pad 4, a buckle 5, a cheek support frame 6, a support sleeve 7, and an adjustment component. The elastic band 1 has two parts, left and right. Pull rings 2 are connected to the front of each elastic band 1. A strap 3 is connected between the pull rings 2. Both sides of the strap 3 are made of elastic material. A soft pad 4 is connected to the back of the strap 3. The soft pad 4 has five ventilation holes for ventilation. A buckle 5 is located between the back of the elastic band 1. The cheek support frame 6 is connected to the lower side of the soft pad 4. The support sleeve 7 is rotatably connected to the lower part of the cheek support frame 6. The support sleeve 7 has an oval structure to fit the side of the user's chin. An adjustment component is provided on the cheek support frame 6.

[0021] like Figure 3 and Figure 4 As shown, the adjustment assembly includes a sliding sleeve 8, an adjusting rod 9, a traction block 10, a screw 11, and a limiting block 12. The left and right sides of the cheek support frame 6 are slidably connected to the sliding sleeve 8, and the adjusting rod 9 is slidably connected between the sliding sleeves 8. The middle of the adjusting rod 9 is slidably connected to the left and right traction blocks 10. The traction blocks 10 and the sliding sleeve 8 are threadedly connected to the screw 11. The screw 11 is equipped with a knob for easy gripping. The sliding sleeve 8 and the traction block 10 are slidably connected to the limiting block 12. The limiting block 12 is rotatably connected to its adjacent screw 11. The cheek support frame 6 and the adjusting rod 9 are engaged with their adjacent limiting blocks 12.

[0022] When using this device, first, place the elastic band 1 on the user's head, ensuring the soft pad 4 contacts and conforms to the user's forehead. Then, secure the device to the user's head using the buckle 5. The left and right sides of the strap 3 are made of elastic material, allowing for a secure fit through the cooperation of the elastic band 1, strap 3, and soft pad 4, preventing displacement due to insufficient fit in certain areas. After securing, position the cheek support frame 6 on both sides of the user's cheeks, and place the support sleeve 7 on the side of the user's chin. Then, fix the traction rope to the traction block 10 and apply traction to the user's teeth. When adjusting the traction point, rotate the screw 11 on the sliding sleeve 8. The screw 11 moves outward under the action of the thread, causing the limiting block 12 to move outward, so that the limiting block 12 no longer contacts the cheek support frame 6. Then, adjust the position by moving the screw up and down. The lever 9 moves the sliding sleeve 8 on the cheek support frame 6 to adjust the height of the traction block 10. Then, the adjusting rod 9 is moved back and forth on the sliding sleeve 8 to adjust the distance between the traction block 10 and the user's lips. After adjustment, the screw 11 is rotated so that it moves inward under the action of the thread, causing the limiting block 12 to move inward, so that the cheek support frame 6 and the adjusting rod 9 are engaged with the limiting block 12. Then, the screw 11 on the traction block 10 is rotated so that it moves outward under the action of the thread, causing the limiting block 12 to move outward, so that the limiting block 12 no longer contacts the adjusting rod 9. Then, the traction block 10 is moved left and right on the adjusting rod 9, so that the traction block 10 can be moved up and down, left and right, and back and forth as needed, which facilitates flexible adjustment of the traction point.
