Description

Technical Field

[0001] This invention relates to the technical field of dental traction devices, specifically a traction device for impacted teeth. Background Technology

[0002] Impacted teeth typically refer to newly erupted permanent teeth that fail to erupt normally. The harm caused by impacted teeth can lead to malformation of adjacent teeth and reduce biting ability. Orthodontic traction is a common method in orthodontics, primarily used to correct impacted or crooked teeth. For impacted teeth, traction requires surgical intervention through a window opening. A traction device is commonly used to pull the impacted tooth through an adhesive bonding process. During orthodontic traction of impacted teeth, as the impacted tooth is gradually pulled out, the traction force of the device needs constant adjustment. Too much or too little force will negatively impact the traction effect, so flexible adjustment is necessary. Furthermore, the traction of impacted teeth at different stages requires different directions and angles based on the actual position of the impacted tooth to achieve better results. Existing traction devices are mostly basic linear traction, which is insufficient for achieving the desired effect. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Combined with appendix Figures 1-9 The aforementioned traction device for impacted teeth includes a winding mechanism 61 disposed on one side of the adhesive plate 13.

[0022] The winding mechanism 61 includes a traction member 12 connected to the adhesive plate 13. One end of the traction member 12, away from the adhesive plate 13, is wound around a drum 16. The drum 16 is rotatably mounted on a drum connecting plate 15. The drum 16 is fixedly connected to an adjusting shaft 20, which is rotatably connected to the drum connecting plate 15. A locking hole 29 is equidistantly arranged inside the drum 16. A limiting post 17 is fixedly mounted on the drum connecting plate 15, and a sliding feature is provided on the drum connecting plate 15. A locking rod 18 is fixedly connected to the drum connecting plate 15 via a first spring 19. The locking rod 18 can be locked in conjunction with the first locking hole 29. The locking rod 18 can also be engaged with the limiting post 17. A direction adjustment mechanism 62 is provided below the drum connecting plate 15. The direction adjustment mechanism 62 is used to assist in the three-dimensional adjustment of the direction and angle of the winding mechanism 61. The traction member 12 can preferably be one of the commonly used traction materials for dental impacted tooth traction, such as a chain, metal wire, or other materials.

[0023] Advantageously, the direction adjustment mechanism 62 includes a limiting rod 22 that is slidably connected to the drum connecting plate 15. The limiting rod 22 is fixedly connected to the connecting plate 24. A screw 21 is also rotatably provided on the connecting plate 24. The screw 21 is helically driven to the drum connecting plate 15. A nut 23 is also rotatably provided on the connecting plate 24. The nut 23 is fixedly connected to the screw 21.

[0024] Advantageously, the side of the connecting plate 24 away from the drum connecting plate 15 is fixedly connected to the first rotating block 25. The first rotating block 25 is rotatably connected to the second rotating block 26. The first rotating block 25 has second locking holes 30 arranged at equal intervals. The second rotating block 26 is fixedly provided with a connecting rope 28. The connecting rope 28 is fixedly provided with a pin 27 away from the fixed end of the second rotating block 26. The pin 27 can cooperate with the second locking hole 30 to lock.

[0025] Advantageously, a locking plate 31 is also fixedly provided on the second rotating block 26. The locking plate 31 is provided with a pair of locking pins 32, which can cooperate with the corresponding third locking hole 33. The third locking hole 33 is equidistantly arranged on the fixed sleeve 14. A slide rail 34 is slidably provided on the fixed sleeve 14. A slide plate 35 is slidably provided on the slide rail 34. A slide rod 36 is equidistantly arranged and fixed on the slide plate 35. The slide rod 36 is slidably connected to the second rotating block 26. A second spring 37 is fixedly provided between the second rotating block 26 and the slide plate 35. The elastic force of the second spring 37 is large enough that it is not easy to deform the second spring 37 during the tooth traction process. Only when a large force is applied can the second spring 37 be deformed, so that the locking pin 32 can be pulled out from the third locking hole 33. The fixed sleeve 14 is fixedly provided on the dental brace thread 11.

[0026] How to use this invention:

[0027] In the initial state:

[0028] The drum 16 does not have any excess traction member 12 wound inside. The locking rod 18 is inserted into the first locking hole 29 to lock the drum 16. The pin 27 is inserted into the second locking hole 30 to lock the first rotating block 25. The first spring 19 is in the normal state. The side of the drum connecting plate 15 near the fixing sleeve 14 is in contact with the nut 23. The second spring 37 is in the normal state. The locking pin 32 is inserted into the third locking hole 33 to lock the second rotating block 26.

[0029] When using this device, the user needs to install it on the patient's dental brace wire 11 and attach the adhesive plate 13 to the patient's impacted tooth. The user then uses tweezers or other tools as needed. The user manually lifts the reel connecting plate 15. Lifting the reel connecting plate 15 raises the second rotating block 26, stretching the second spring 37. As the second rotating block 26 is lifted, the locking pin 32 is pulled out of the third locking hole 33. The user adjusts the angle of the second rotating block 26 as needed. After adjustment, the user stops pulling on the second rotating block 26, causing it to reset under the action of the second spring 37. The locking pin 32 is then reinserted into the other third locking hole 33, thus locking the second rotating block 26. The user then needs to use a tool to pull out the pin 27. Once the pin 27 is pulled out, it disengages from the second locking hole 30, and the first rotating block 25 is no longer locked. The user manually adjusts the angle of the first rotating block 25 according to actual needs. After adjusting the first rotating block 25, the user inserts the pin 27 back into the locking hole 33 using a tool. The second rotating block 26 is inserted into the second locking hole 30, allowing the pin 27 to pass through it, thus reusing the first rotating block 25. The user then uses a tool to move the nut 23 as needed. The rotation of the nut 23 drives the screw 21 to rotate, controlling the lifting and lowering of the drum connecting plate 15 through the screw drive between the screw 21 and the drum connecting plate 15. By controlling the position of the drum connecting plate 15 and the angle of the first rotating block 25, the traction direction and angle of the traction member 12 on the embedded tooth are controlled. Then, the user, according to actual needs, uses a tool to... Pulling out the locking rod 18 stretches the first spring 19, causing the locking rod 18 to rotate and be placed on the limiting post 17, thus freeing the first locking hole 29 from being locked by the locking rod 18. The user then manually rotates the adjusting shaft 20 using a tool. The rotation of the adjusting shaft 20 drives the reel 16 to rotate, thus beginning to wind up the traction member 12 until it is taut and maintains appropriate tension on the impacted tooth. The user then uses a tool to reset the locking rod 18 and the first spring 19, allowing the locking rod 18 to re-insert into the first locking hole 29, thus maintaining traction on the impacted tooth. This process can be maintained for a period of time. When the patient's impacted tooth traction shows initial effectiveness and the traction force of the traction member 12 needs to be readjusted, the adjusting shaft 20 is rotated again to further wind up the traction member 12, and the angle and direction are readjusted according to actual needs.
