DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] The following describes in detail a technical solution of an orthodontic traction device provided by various embodiments of the present invention in conjunction with the accompanying drawings.

[0028] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides an oral orthodontic traction device, including a traction seat 1, two traction soft pipes 12 are respectively provided at both ends of the traction seat 1, each of the traction soft pipes 12 is provided with a correction arch wire 2, the correction arch wire 2 and the traction soft pipe 12 are slidably matched, the interior of the traction seat 1 is provided with a traction connection structure 3 for connecting the correction arch wire 2, the traction connection structure 3 is provided with a first adjustment structure 4 for adjusting the correction arch wire 2, and the middle position of the traction seat 1 is also provided with a second adjustment structure 5 for adjusting the correction arch wire 2, the traction seat 1 is provided with a mounting cover 11, and the correction arch wire 2 is provided with a bracket 21. The bracket 21 is installed on the tooth that needs orthodontics during use, and the mounting cover 11 is in a closed state during use.

[0029] The traction soft tube 12 can be changed as the angle of the correction arch wire 2 changes.

[0030] In this embodiment, two long notches 13 are provided in the middle of the traction soft pipe 12. During use, the long notches 13 allow the correction arch wire 2 to move outward from the long notches 13 so as to perform orthodontic work on the teeth at different positions.

[0031] In this embodiment, the traction connection structure 3 includes a connecting block 31, a connecting seat 32, a latch rod 33, a front connecting frame 34 and a rear connecting frame 35. The connecting block 31 is connected to the end position of the correction arch wire 2, the connecting seat 32 is plugged into the connecting block 31, the latch rod is plugged between the connecting block 31 and the connecting seat 32, the front connecting frame 34 is horizontally connected to the connecting seat 32, the front connecting frame 34 is provided with a threaded connecting bolt 36, the rear connecting frame 35 is provided with a connecting rod 37, and the connecting rod 37 is sleeved in the connecting bolt 36.

[0032] Specifically, when the correction arch wire 2 is connected, the connection bolt 36 is loosened, and the position of the connection rod 37 is inserted into the connection bolt 36, and then the connection bolt 36 is connected to the front connection frame 34, so that the connection rod 37 is sleeved into the connection bolt 36, and the connection block 31 is inserted into the plug-in connection seat 32, and then the position of the plug-in rod is inserted, so as to realize the connection of the correction arch wire 2.

[0033] During the process of connecting and using the correction arch wire 2, the angle change of the correction arch wire 2 can make the connecting rod 37 on the rear connecting frame 35 move on the connecting bolt 36 on the front connecting frame 34, thereby realizing the rotation of the correction arch wire 2 during the process of changing the angle;

[0034] During the orthodontic traction process of the teeth, the angle of the correction archwire 2 can be changed and altered; the appropriate archwire angle can make the correction force more effectively transmitted to the teeth and periodontal tissues, reduce the loss and dispersion of force, thereby speeding up the movement of the teeth and shortening the overall time of orthodontic treatment.

[0035] Precise control of tooth movement: By adjusting the angle of the corrective archwire 2, the doctor can more accurately control the direction and degree of tooth movement in three-dimensional space, so that the teeth can move in the expected direction, such as translation, rotation, tilt, etc., thereby achieving a more ideal tooth arrangement and occlusion relationship.

[0036] Solving complex malocclusions: For some complex malocclusions, such as deep overbite, deep overjet, open bite, etc., it is necessary to apply correction forces of different directions and magnitudes to different teeth. The variable angle correction archwire 2 can provide personalized correction force for each tooth according to the specific situation, better solve complex orthodontic problems, and achieve a more perfect correction effect. For example, when correcting deep overbite, by adjusting the angle of the archwire, the front teeth can be lowered and the back teeth can be raised, thereby improving the bite depth.

[0037] In this embodiment, the first adjustment structure 4 includes a mounting seat 41, and both ends of the mounting seat 41 are respectively provided with vertically arranged mounting sleeves 42, and the side wall of each mounting sleeve 42 is provided with a motor seat 43, and the motor seat 43 is provided with an adjustment motor 44, and the main shaft of the adjustment motor 44 is provided with an adjustment gear 45, and each mounting sleeve 42 is provided with a sliding column 46 that slides up and down, and the sliding column 46 is provided with a plurality of tooth grooves 47 that are connected to the inner ring of the adjustment gear 45, and a mounting plate 48 is provided between the two sliding columns 46; a top adjustment wheel 6 is provided at the top middle position of the mounting plate 48.

[0038] Specifically, in the process of adjusting the tightness of the correction arch wire 2, the two adjustment motors 44 work simultaneously and drive the two adjustment gears 45 to rotate in the plurality of tooth grooves 47 on the two sliding posts 46, respectively, thereby driving the positions of the two sliding posts 46 to move upward on the two mounting sleeves 42, respectively. The upward movement of the positions of the two sliding posts 46 will drive the position of the top adjustment wheel 6 on the mounting plate 48 to move upward, and the upward movement of the position of the top adjustment wheel 6 will cause the position of the traction rope 8 to move upward, and during use, the traction rope 8 will be tightened and the tightness will be adjusted, thereby adjusting the tightness of the correction arch wire 2;

[0039] In this embodiment, the second adjustment structure 5 includes an adjustment seat 51, a driving motor 52, a driving bidirectional screw rod 53 and two adjustment blocks 54. The adjustment seat 51 is horizontally arranged, and a horizontally arranged sliding rod 55 is provided on the adjustment seat 51. The driving bidirectional screw rod 53 is rotatably connected to the adjustment seat 51. The driving motor 52 is located on the side wall of the adjustment seat 51 and is transmission-connected to the driving bidirectional screw rod 53. The two adjustment blocks 54 are symmetrically arranged. The adjustment blocks 54 are threadedly connected to the driving bidirectional screw rod 53, and the adjustment blocks 54 are slidably matched with the sliding rod 55. A top traction roller 7 is provided on the top of each adjustment block 54. A traction rope 8 is sleeved on the top traction roller 7, and the traction rope 8 passes through the top adjustment wheel 6 and is connected to the rear connecting frame 35.

[0040] Specifically, during use, when the elastic band of the bidirectional correction arch wire 2 is adjusted, the driving motor 52 works to drive the bidirectional screw rod 53 to rotate on the adjustment seat 51. The driving bidirectional screw rod 53 rotates, which drives the positions of the two adjustment blocks 54 to move relative to or away from each other on the slide bar 55. The movement of the adjustment block 54 drives the position of the top traction roller 7 to move, thereby driving the position of the correction arch wire 2 to move horizontally, thereby adjusting the tightness of the correction arch wire 2.

[0041] The benefit of adjusting the tightness of the correction arch wire 2 is the precise control of tooth movement: by adjusting the tightness of the correction arch wire 2, the force applied to the teeth can be precisely controlled, so that the teeth can achieve accurate translation, rotation, tilt and other movements in three-dimensional space according to the design of the orthodontist, thereby achieving an ideal tooth arrangement and occlusion relationship.

[0042] Solve complex orthodontic problems: For some complex malocclusions such as severe crowding, open bite, deep overbite, deep overjet, etc., different correction forces are required at different stages of the treatment process. Timely adjustment of the archwire tension can provide just the right force for specific problems at each stage and effectively solve complex orthodontic problems.
