Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a device for a tooth traction fulcrum. Background Art

[0002] Inverted impacted teeth are a special type of impacted teeth. Current clinical treatment methods include post-extraction restoration, autologous tooth transplantation, and orthodontic traction treatment. Orthodontic traction treatment has the advantages of preserving healthy and beautiful teeth and periodontal tissues.

[0003] Orthodontic traction treatment of inverted impacted teeth first requires rotating the teeth around a precise fulcrum to a certain tooth axis direction within a limited tissue space. The establishment of a "rotational motion" traction system is the key and difficulty to successful treatment. The teeth are rotated in the alveolar bone so that the crowns and roots face the normal direction, and then the teeth are arranged in the normal position of the dental arch. Rotating the teeth to the normal direction is a relatively difficult process clinically.

[0004] There are many types of existing dental traction fulcrum devices, but there is still a risk of teeth penetrating the alveolar bone during traction, resulting in failure of dental traction treatment. In addition, most devices are cumbersome to use and require constant debugging of components to adjust the overall use of the device, which is inconvenient to use. Summary of the invention

[0005] The purpose of the present invention is to provide a device for a tooth traction fulcrum to solve the problems raised in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A device for a tooth traction fulcrum comprises a mounting box, one side of which is fixedly connected to a bonding base plate, the other side of which is provided with an arc-shaped buckle, the inner wall of which is provided with an implanting nail assembly, and one end of which is provided with a traction hook.

[0007] Further preferably, the implant nail assembly includes a telescopic shell, a universal ball fixedly connected to one end of the telescopic shell, a telescopic rod threadedly engaged with the inner wall of the telescopic shell, one end of the telescopic rod is fixedly connected to the traction hook, and the universal ball movably engages in the arc buckle.

[0008] Further preferably, an assembly frame is slidably installed inside the installation box, a drive motor is installed inside the assembly frame, an arc buckle is fixedly installed on the side end of the drive motor, threaded rods are rotatably installed on the left and right sides of the arc buckle, a universal ball is rotatably installed inside the arc buckle, and a traction hook is installed on the side end of the universal ball

[0009] Further preferably, two reserved grooves are opened inside the installation box, and two limit grooves are opened on the upper end of the installation box. A blocking block is slidably installed inside each of the limit grooves, and a dust strip can be installed on the side end of the bonding bottom plate away from the installation box.

[0010] Further preferably, rotating rods are rotatably mounted on both the left and right sides of the driving motor, and the outer surface of each rotating rod is sleeved with a first rotating gear.

[0011] Further preferably, brackets are fixedly installed on both the left and right sides of the arc-shaped buckle, and a transmission rod is rotatably installed inside each of the brackets, wherein the side end portion of each of the transmission rods is meshed with the first rotating gear.

[0012] Further preferably, second rotating gears are rotatably mounted on both left and right sides of the arc-shaped buckle, and a threaded rod is mounted inside each of the second rotating gears.

[0013] Further preferably, a side end portion of each threaded rod is fixedly mounted with an anti-skid pad, and each of the second rotating gears is meshed with the other side of the transmission rod.

[0014] Further preferably, a release paper is provided on one side of the adhesive base plate, and an easy-tear strip is fixedly connected to one side of the release paper.

[0015] Further preferably, the shape of the arc-shaped buckle is C-shaped, the diameter at the center of the inner wall of the arc-shaped buckle is larger than the diameters on both sides of the inner wall, and the shape of the traction hook is a transverse U-shape.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, the release paper is torn off and separated from the adhesive base plate, and then the device is adhered to the tooth neck along the adhesive base plate, and then the use angle of the device is adjusted along the arc buckle and the universal ball to cooperate with the telescopic shell and the telescopic rod to adjust the use position of the traction hook, which is convenient for connection with the intraoral arch wire. When the device is in use, the traction fulcrum can be quickly and conveniently built and set, thereby facilitating subsequent correction operations, improving the safety of the device, and enhancing the use effect of the device.

[0018] Specifically, by setting up the implant screw assembly, when the equipment is in use, the universal ball at one end of the telescopic shell can be connected to the arc-shaped buckle connected to the mounting shell, and the traction hook can be rotated to extend the telescopic rod. After adjusting to the appropriate length and angle, the traction hook can be connected to the intraoral arch wire. After the connection is completed, the traction fulcrum is set, and then the appliance is pulled to rotate the crown and root of the impacted tooth in the normal direction. When the impacted tooth rotates, the alveolar bone of the palatal tooth neck is a stress concentration area, which may cause adverse bone absorption. The implant screw head can bear the stress on the alveolar bone of the palatal tooth neck during the rotational movement of the tooth, and play a certain protective role on the palatal alveolar bone.

[0019] The present invention has another feature. While the above-mentioned technical solution can meet the use requirements, another set of technical solutions is provided, that is, by starting the driving motor to drive the rotating rod to rotate, thereby driving the first rotating gear to rotate, and then the transmission rod drives the second rotating gear to rotate. The second rotating gear rotates to cooperate with the threaded rod to push the two anti-slip pads inside the arc-shaped buckle to move closer to the middle to clamp and fix the universal ball, so that the device can be quickly reinforced and limited when in use, thereby improving the stability of the device and further enhancing the safety of the device.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 technical personnel in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 to Figure 2 One embodiment of the present invention provides the following technical solution:

[0029] A device for a tooth traction fulcrum comprises a mounting box 1, one side of which is fixedly connected to a bonding base plate 13, the other side of which is provided with an arc-shaped buckle, the inner wall of which is provided with an implanting nail assembly, and one end of which is provided with a traction hook 33.

[0030] The implant nail assembly includes a telescopic shell 3, a universal ball 31 fixedly connected to one end of the telescopic shell 3, a telescopic rod 32 threadedly engaged with the inner wall of the telescopic shell 3, one end of the telescopic rod 32 is fixedly connected to the traction hook 33, and the universal ball 31 is movably engaged in the arc buckle.

[0031] One aspect of the application of this embodiment is: when in use, pull the tear strip to separate the release paper from the adhesive base plate 13, and then adhere the adhesive base plate 13 to the neck of the tooth, and then fix the traction hook 33 to the intraoral arch wire; bond the orthodontic appliance to the incisal end of the tooth for traction treatment, so that the tooth rotates in the alveolar bone under the action of the traction fulcrum, so that the crown and root face in the normal direction, and then the tooth is arranged in the normal position of the dental arch, and as the angle between the long axis of the tooth and the rotation fulcrum changes during the traction process, the effect of offsetting the adverse component force gradually increases, which helps to invert the rotation movement of the impacted tooth.

[0032] By setting up the implant screw assembly, when the device is in use, the universal ball 31 at one end of the telescopic shell 3 can be connected to the arc-shaped buckle connected to the mounting shell, and the traction hook 33 can be rotated to extend the telescopic rod 32. After adjusting to a suitable length and angle, the traction hook 33 can be connected to the intraoral arch wire. After the connection is completed, the traction fulcrum is set, and then the orthodontic appliance is pulled to rotate the crown and root of the impacted tooth in a normal direction. When the impacted tooth rotates, the alveolar bone of the palatal tooth neck is a stress concentration area, which may cause adverse bone absorption. The head of the implant screw can bear the stress on the alveolar bone of the palatal tooth neck during the rotation of the tooth, and play a certain protective role on the palatal alveolar bone.

[0033] One side of the arc-shaped buckle of the present embodiment is fixedly connected with a connecting block, and the connecting block is slidably fitted on the inner wall of the installation box 1; by providing the connecting block, the implant nail assembly can be separated from the installation box 1, which facilitates the selection of a suitable bonding base plate 13 for use, thereby improving the convenience of using the equipment.

[0034] See also Figures 3 to 6 Another embodiment of the present invention provides the following technical solution:

[0035] A device for a tooth traction fulcrum comprises a mounting box 1, one side of which is fixedly connected to a bonding base plate, the other side of which is provided with an arc-shaped buckle, the inner wall of which is provided with an implanting nail assembly, and one end of which is provided with a traction hook 33.

[0036] An assembly frame is slidably installed inside the installation box 1, and a driving motor is installed inside the assembly frame 2. An arc-shaped clip 22 is fixedly installed on the side end of the driving motor, and threaded rods are rotatably installed on the left and right sides of the arc-shaped clip 22. A universal ball 31 is rotatably installed inside the arc-shaped clip 22, and a traction hook 33 is installed on the side end of the universal ball 31.

[0037] Two reserved grooves 11 are provided inside the installation box 1, and two limiting grooves 12 are provided at the upper end of the installation box 1.

Rotating rods are rotatably installed on the left and right sides of the driving motor, and the outer surface of each rotating rod is sleeved with a first rotating gear. Brackets are fixedly installed on the left and right sides of the arc buckle 22, and a transmission rod is rotatably installed inside each of the brackets, wherein the side end of each transmission rod is meshed with the first rotating gear. Second rotating gears are rotatably installed on the left and right sides of the arc buckle, and a threaded rod is installed inside each of the second rotating gears. An anti-slip pad is fixedly installed on the side end of each threaded rod, and each of the second rotating gears is meshed with the other side of the transmission rod.

[0038] In this embodiment, Figure 3-6 As shown, two reserved grooves 11 are provided inside the installation box 1, and two limit grooves 12 are provided at the upper end of the installation box 1. A blocking block 15 is slidably installed inside each limit groove 12, and a dustproof strip is installed at the side end of the bonding bottom plate 13 away from the side of the installation box 1. This structure can facilitate the limited installation of the assembly frame 2 and the installation box 1 by cooperating with the upper limit groove 12 through the blocking block 15.

[0039] In this embodiment, rotating rods 23 are rotatably installed on both sides of the driving motor 21, and the outer surface of each rotating rod 23 is sleeved with a first rotating gear 24. This structure can drive the rotating rod 23 to rotate through the driving motor 21 and then drive the first rotating gear 24 to rotate.

[0040] Brackets 25 are fixedly installed on both sides of the arc buckle 22, and a transmission rod 26 is rotatably installed inside each bracket 25, wherein the side end of each transmission rod 26 is meshed with the first rotating gear 24. This structure can be supported by the bracket 25 so as to facilitate connection and use after the transmission rod 26 is installed.

[0041] The left and right sides of the arc buckle 22 are both rotatably installed with second rotating gears 27, and each second rotating gear 27 is internally installed with a threaded rod 28. This structure can drive the second rotating gear 27 to rotate through the transmission rod 26 and then cooperate with the threaded rod 28 to facilitate the use of subsequent components.

[0042] The side end of each threaded rod 28 is fixedly mounted with an anti-skid pad 29, and each second rotating gear 27 is meshed with the other side of the transmission rod 26. This structure can cooperate with the threaded rod 28 through the second rotating gear 27.

[0044] The use method and advantages of the present invention: When using the device of the tooth traction fulcrum, the working process is as follows: first, when using it, the user sticks the device along one side of the bonding base plate 13 to the tooth neck, and then adjusts the use angle of the telescopic shell 3 and the traction hook 33 along the arc buckle 22 in conjunction with the universal ball 31, and then rotates the telescopic shell 3 and the telescopic rod 32 to adjust the use length of the telescopic shell 3, and adjusts the traction hook 33 to a suitable position and angle for convenient connection with the intraoral arch wire. After the connection is completed, the user operates the remote controller, and the receiver inside the drive motor 21 starts the drive motor 21 after receiving the signal. (In the current existing technology, remote signal control of motor movement is already a very mature technology, such as remote control door motors, etc., so it will not be repeated here.) The drive motor 21 drives the rotating rod 23 to rotate and then drives the first The rotating gear 24 rotates, and the transmission rod 26 transmits the rotation to drive the second rotating gear 27. When the second rotating gears 27 on both sides of the arc buckle 22 rotate, the internal threads drive the threaded rod 28 to rotate and advance, thereby bringing the two anti-slip pads 29 hidden in the inner wall of the arc buckle 22 closer to the middle, and then squeezing the universal ball 31 to fix and clamp the universal ball 31 to improve the stability of the device. After the traction fulcrum is set, the orthodontic appliance is pulled to rotate the crown and root of the impacted tooth in the normal direction. When the impacted tooth rotates, the alveolar bone of the palatal tooth neck is a stress concentration area, which may cause adverse bone absorption. The head of the implant nail can bear the stress on the alveolar bone of the palatal tooth neck during the rotation of the tooth, and play a certain protective role on the palatal alveolar bone.

[0045] One side of the adhesive base plate of the above two embodiments is equipped with release paper, and one side of the release paper is fixedly connected with an easy-tear strip; by providing the release paper, the adhesive base plate can be protected to prevent contamination by contact with external impurities, and by providing the easy-tear strip, the release paper can be easily removed.

[0046] The shape of the traction hook 33 of the present embodiment is a transverse U-shape; by providing the traction hook 5, it is convenient to connect the intraoral archwire and increase the fixing effect of the device.

[0047] The shape of the arc buckle 22 of this embodiment is C-shaped, and the diameter at the center of the inner wall of the arc buckle 22 is larger than the diameter on both sides of the inner wall; the arc buckle 22 is provided to limit the universal ball 31 to prevent the universal ball 31 from separating from the arc buckle 3 when force is applied, and at the same time fit with the universal ball 31 to increase the stability of the rotation of the universal ball 31, thereby improving the smoothness of the rotation of the device on the impacted tooth.
