Description

Technical Field

[0001] This invention belongs to the field of orthodontic technology, and specifically relates to a bone screw hook device for orthodontic treatment. Background Technology

[0002] Orthodontic anchorage screws, also known as micro-screw implants, bone screws, implant screws, or pins, are devices that act as fixation points for orthodontic forces during treatment. Typically made of stainless steel or titanium alloy, they are implanted into the bone tissue to provide absolute anchorage, helping to control tooth movement and preventing unnecessary movement of other teeth. They can be used to improve conditions such as protruding lips, deep overbite, and reverse overbite, or to address orthodontic needs such as moving posterior teeth forward or narrowing gaps between teeth. The implantation process is relatively safe with low risk, and patients generally do not experience severe discomfort after the procedure.

[0003] Existing bone screw devices for orthodontic treatment typically have openings on the outside to secure traction elastics or ligatures. This requires precise positioning of the traction and manual pulling of the traction direction, making them impractical. Furthermore, when in use, the nuts pressing tightly against the gums can cause inflammation around the bone screws, leading to the need for secondary or multiple orthodontic treatments. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a bone screw hook device for orthodontic treatment, which features easy adjustment of the traction direction, convenient fixation of the ligature wire, and reduced inflammation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bone screw hook device for orthodontic treatment, comprising an anchorage screw, wherein a nut is provided at the top of the anchorage screw, a threaded hole is provided at the center of the top of the nut, a universal adjustment mechanism is provided on the inner side of the threaded hole, a threaded hole is provided on the outer side of the nut, a traction fixing mechanism is provided on the inner side of the threaded hole, a traction elastic band is provided on one side of the traction fixing mechanism, and a fixing suspension mechanism is provided at the lower end of the side of the nut.

[0006] The universal adjustment mechanism includes a screw, a universal ball joint is fixedly connected to the top of the screw, an extension mechanism is provided on one side of the universal ball joint, and a universal hook is provided on one side of the extension mechanism.

[0007] Preferably, the extension mechanism includes a second screw, an internally threaded cap is provided on the outer side of the second screw, an extension rod is fixedly connected to one side of the internally threaded cap, and an external thread is provided at the other end of the extension rod.

[0008] Preferably, the inner side of the extension rod is provided with a weight-reducing hole, and a support rod is uniformly fixedly connected to the side of the weight-reducing hole.

[0009] Preferably, a reinforcing rod is fixedly connected to the lower side of the universal ball joint, and a reinforcing chassis is fixedly connected to the bottom of the reinforcing rod.

[0010] Preferably, the bottom of the reinforced chassis is fixedly connected with anti-slip balls, and an anti-slip groove is provided on the side of the nut located below the anti-slip balls.

[0011] Preferably, the traction fixing mechanism includes a hollow screw, the outer side of which is provided with fine threads, and a knot is provided at one end of the traction rubber band near the hollow screw.

[0012] Preferably, the outer side of the nut near the hollow screw has an internally clipped anti-slip square groove.

[0013] Preferably, the fixed suspension mechanism includes a threaded hole three, a screw three is provided on the inner side of the threaded hole three, and a fixed hook is provided on one side of the screw three.

[0014] Preferably, a connecting rod is fixedly connected to the bottom of the nut on one side below the screw, and a circular base is fixedly connected to the bottom of the connecting rod.

[0015] Preferably, a filler pin is provided on the outer side of the nut near the threaded hole three.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention features a universal adjustment mechanism. Screw 1 is used to separate and install the universal ball head, and screw 2 is used to install the extension rod, making the position of the universal hook more suitable for the position of the traction elastic band. The universal hook is connected to the extension rod through internal threads. In use, one end of the elastic band is connected to the brace bracket, and the other end is connected to the universal hook. Because the universal ball head can rotate arbitrarily, the traction elastic band can be connected to the anchorage screw from any direction. The weight-reducing hole makes the extension rod hollow, which can reduce weight and reduce the burden on the teeth. At the same time, the support rod can increase the overall strength of the extension rod and prevent excessive bending. When screw 1 is connected to the nut, the reinforcing rod and the reinforcing base can resist the nut, and the stability of screw 1 is enhanced by the interaction force. The anti-slip ball is embedded in the anti-slip groove, which can act as a gasket for anti-slip. By rotating the extension rod on the universal ball head, the traction direction can be adjusted at will, which is more suitable for dentists to operate.

[0018] 2. This invention is equipped with a traction fixation mechanism. When the patient's oral environment is not suitable for the universal ball joint or the teeth are under great pressure and the weight of the bone screw cannot be increased, the second threaded hole is needed to bind the traction elastic band or binding wire. When using it, the traction elastic band is passed through the hollow screw and a knot is tied to fix one end of the traction elastic band in the hollow screw. The hollow screw is then screwed into the second threaded hole, and one end of the traction elastic band is fixed to the bracket of the brace. The binding wire is passed through the second threaded hole and wrapped with a nut, and then embedded in the inner buckle anti-slip square groove to prevent the binding wire from slipping. By passing the elastic band or binding wire through the second threaded hole, the practicality of the device can be improved, thus adapting it to different patients.

[0019] 3. This invention features a fixed suspension mechanism. When a rigid fixation of the traction rope is required, screw three is screwed into threaded hole three, which can fix the fixing hooks to the six sides of the nut. The fixing hooks are used to connect the traction rubber band and the nut, and the connection method is relatively rigid, which can achieve a better correction effect. The connecting rod is located on the bottom side of the nut, connecting the circular base and the nut. When the anchoring pin is screwed into the gum, the circular base abuts against the gum, preventing the bottom side of the nut from directly contacting the gum, facilitating the flow of food at the bottom. The filling pin nut is cylindrical and screwed into threaded hole three, which just fills the gap and prevents food from being retained. By screwing screw three into the threaded hole, the connection methods of the hooks can be increased, further improving the practicality. Attached Figure Description

[0027] 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.

[0028] Example 1

[0029] Please see Figure 1-6 The present invention provides the following technical solution: a bone screw hook device for orthodontic treatment, including an anchorage screw 1, a nut 2 is provided on the top of the anchorage screw 1, a threaded hole 3 is provided at the center of the top of the nut 2, a universal adjustment mechanism 4 is provided on the inner side of the threaded hole 3, a threaded hole 5 is provided on the outer side of the nut 2, a traction fixing mechanism 6 is provided on the inner side of the threaded hole 5, a traction elastic band 7 is provided on one side of the traction fixing mechanism 6, and a fixing suspension mechanism 8 is provided at the lower end of the side of the nut 2.

[0030] The universal adjustment mechanism 4 includes a screw 41, a universal ball head 42 fixedly connected to the top of the screw 41, an extension mechanism 43 on one side of the universal ball head 42, and a universal hook 44 on one side of the extension mechanism 43.

[0031] Specifically, the extension mechanism 43 includes a second screw 431, with an internal thread cap 432 on the outer side of the second screw 431. An extension rod 433 is fixedly connected to one side of the internal thread cap 432, and an external thread 434 is provided at the other end of the extension rod 433. By adopting the above technical solution, the first screw 41 is used to separate and install the universal ball head 42, and the second screw 431 is used to install the extension rod 433, so that the position of the universal hook 44 is more suitable for the position of the traction rubber band 7. The universal hook 44 is connected to the extension rod 433 through the internal thread. In use, one end of the rubber band is connected to the dental bracket, and the other end is connected to the universal hook 44. Because the universal ball head 42 can rotate arbitrarily, the traction rubber band 7 can be connected to the anchoring nail 1 from any direction.

[0032] Specifically, a weight-reducing hole 435 is provided on the inner side of the extension rod 433, and a support rod 436 is uniformly fixedly connected to the side of the weight-reducing hole 435. By adopting the above technical solution, the weight-reducing hole 435 makes the inside of the extension rod 433 hollow, which can reduce the weight and reduce the burden on the teeth. At the same time, the support rod 436 can increase the overall strength of the extension rod 433 and prevent excessive bending.

[0033] Specifically, a reinforcing rod 45 is fixedly connected to the lower side of the universal ball joint 42, and a reinforcing base 46 is fixedly connected to the bottom of the reinforcing rod 45. By adopting the above technical solution, when the screw 41 is connected to the nut 2, the reinforcing rod 45 and the reinforcing base 46 can resist the nut 2, and the stability of the screw 41 is enhanced by the interaction force.

[0034] Specifically, the bottom of the reinforced chassis 46 is fixedly connected with anti-slip ball 47, and the top of the nut 2 is provided with an anti-slip groove 48 on the side below the anti-slip ball 47. By adopting the above technical solution, the anti-slip ball 47 is embedded in the anti-slip groove 48, which can play the role of anti-slip of the pad.

[0035] In this embodiment, screw 41 is used to separate and install the universal ball joint 42, and screw 431 is used to install the extension rod 433, making the position of the universal hook 44 more suitable for the position of the traction elastic band 7. The universal hook 44 is connected to the extension rod 433 through internal threads. In use, one end of the elastic band is connected to the dental brace bracket, and the other end is connected to the universal hook 44. Because the universal ball joint 42 can rotate arbitrarily, the traction elastic band 7 can be connected to the anchoring nail 1 from any direction. The weight reduction hole 435 creates the extension rod 43. 3. The internal hollow design reduces weight and the burden on teeth. At the same time, the support rod 436 increases the overall strength of the extension rod 433 and prevents excessive bending. When the screw 41 is connected to the nut 2, the reinforcing rod 45 and the reinforcing base 46 can hold the nut 2, and the interaction force enhances the stability of the screw 41. The anti-slip ball 47 is embedded in the anti-slip groove 48 and can act as a gasket to prevent slippage. By rotating the extension rod 433 on the universal ball head 42, the traction direction can be adjusted at will, which is more suitable for dentists to operate.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that the traction fixation mechanism 6 includes a hollow screw 61 with a fine thread 62 on the outer side. A knot 63 is provided at one end of the traction elastic band 7 near the hollow screw 61. By adopting the above technical solution, when the patient's oral environment is not suitable for the universal ball head 42 or the teeth are under great pressure and the weight of the bone screw cannot be increased, the threaded hole 2 5 is needed to bind the traction elastic band 7 or the binding wire. When using it, the traction elastic band 7 is passed through the hollow screw 61 and a knot 63 is tied to fix one end of the traction elastic band 7 in the hollow screw 61. The hollow screw 61 is screwed into the threaded hole 2 5 and then the traction elastic band 7 is fixed to the brace bracket.

[0038] Specifically, an inner-locking anti-slip square groove 64 is provided on the outer side of the nut 2 near the hollow screw 61. By adopting the above technical solution, the binding wire passes through the threaded hole 2 5 and then wraps around the nut 2 once, and is embedded in the inner-locking anti-slip square groove 64, which can prevent the binding wire from slipping.

[0039] In this embodiment, when the patient's oral environment is not suitable for the universal ball head 42 or the teeth are under great burden and the weight of the bone screw cannot be increased, the threaded hole 2 5 is needed to bind the traction elastic band 7 or the binding wire. When using it, the traction elastic band 7 is passed through the hollow screw 61 and a knot 63 is tied to fix one end of the traction elastic band 7 in the hollow screw 61. The hollow screw 61 is screwed into the threaded hole 2 5 and then the traction elastic band 7 is fixed to the bracket. The binding wire is passed through the threaded hole 2 5 and wrapped with a nut 2, and embedded in the inner anti-slip square groove 64 to prevent the binding wire from slipping. By passing the elastic band or binding wire through the threaded hole 2 5, the practicality of the device can be improved, thus adapting it to different patients.

[0040] Example 3

[0041] The difference between this embodiment and embodiments 1 and 2 is that the fixed suspension mechanism 8 includes a threaded hole 81, a screw 82 is provided on the inner side of the threaded hole 81, and a fixed hook 83 is provided on one side of the screw 82. By adopting the above technical solution, when it is necessary to rigidly fix the traction rope, and the extension rod 433 and the hollow screw 61 cannot connect to the traction rubber band 7 or achieve the correction effect, the screw 82 can be screwed into the threaded hole 81, thereby fixing the fixed hook 83 to the six sides of the nut 2. The fixed hook 83 is used to connect the traction rubber band 7 and the nut 2, and the connection method is relatively rigid, which can achieve a better correction effect.

[0042] Specifically, a connecting rod 84 is fixedly connected to the bottom of the nut 2 on one side below the screw 82. A circular base 85 is fixedly connected to the bottom of the connecting rod 84. By adopting the above technical solution, the connecting rod 84 is located on the bottom side of the nut 2, connecting the circular base 85 and the nut 2. When the anchorage screw 1 is screwed into the gum, the circular base 85 abuts against the gum, avoiding direct contact between the bottom side of the nut 2 and the gum, and facilitating the flow of food at the bottom.

[0043] Specifically, a filler pin 86 is provided on the outer side of the nut 2 near the threaded hole 81. By adopting the above technical solution, the nut of the filler pin 86 is cylindrical. When screwed into the empty threaded hole 81, it just fills the gap and prevents food from being left behind.

[0044] In this embodiment, when a rigid fixation of the traction rope is required, and neither the extension rod 433 nor the hollow screw 61 can connect to the traction elastic band 7 or achieve the corrective effect, the screw 82 can be screwed into the threaded hole 81 to fix the fixing hook 83 to the six sides of the nut 2. The fixing hook 83 is used to connect the traction elastic band 7 and the nut 2, and the connection method is relatively rigid, which can achieve a better corrective effect. The connecting rod 84 is located on the bottom side of the nut 2 and connects the circular base 85 and the nut 2. When the anchoring nail 1 is screwed into the gum, the circular base 85 abuts against the gum, preventing the bottom side of the nut 2 from directly contacting the gum, which facilitates the flow of food at the bottom. The nut of the filling nail 86 is cylindrical and is screwed into the empty threaded hole 81, which just fills the gap and prevents food from being retained. By screwing the screw 82 into the threaded hole, the connection method of the hook can be increased. It is more traditional but has high stability, which further improves the practicality.

[0045] The working principle and usage process of this invention are as follows: First, all metal parts in this design are made of titanium alloy, including but not limited to the anchor nail 1, nut 2, screw 1 41, universal ball joint 42, and screw 2 431. Screw 1 41 is used to separate and install the universal ball joint 42, and screw 2 431 is used to install the extension rod 433, so that the position of the universal hook 44 is more suitable for the position of the traction rubber band 7. The universal hook 44 is connected to the extension rod 433 through internal threads. In use, one end of the rubber band is connected to the dental brace bracket, and the other end is connected to the universal hook 44. Since the universal ball joint 42 can rotate arbitrarily, the traction rubber band 7 can be connected to the support nail 1 from any direction. The weight reduction hole 435 makes the extension rod 433 hollow inside, which can reduce weight and reduce the burden on the teeth. At the same time, the support rod 436 can increase the overall strength of the extension rod 433 and avoid excessive bending. When the screw 41 is connected to the nut 2, the reinforcing rod 45 and the reinforcing base 46 can resist the nut 2 and enhance the stability of the screw 41 by relying on the interaction force. The anti-slip ball 47 is embedded in the anti-slip groove 48 and can play the role of anti-slip pad.

[0046] Subsequently, when the patient's oral environment is not suitable for the universal ball head 42 or the teeth are under great pressure and the weight of the bone screw cannot be increased, the threaded hole 2 5 is needed to bind the traction elastic band 7 or the binding wire. When using it, the traction elastic band 7 is passed through the hollow screw 61 and a knot 63 is tied to fix one end of the traction elastic band 7 in the hollow screw 61. The hollow screw 61 is screwed into the threaded hole 2 5 and then the traction elastic band 7 is fixed to the bracket. The binding wire is passed through the threaded hole 2 5 and then wrapped around the nut 2 and embedded in the inner anti-slip square groove 64 to prevent the binding wire from slipping.

[0047] Meanwhile, when a rigid fixation of the traction rope is required, and neither the extension rod 433 nor the hollow screw 61 can connect to the traction elastic band 7 or achieve the corrective effect, the screw 82 can be screwed into the threaded hole 81 to fix the fixing hook 83 to the six sides of the nut 2. The fixing hook 83 is used to connect the traction elastic band 7 and the nut 2, and the connection method is relatively rigid, which can achieve a better corrective effect. The connecting rod 84 is located on the bottom side of the nut 2 and connects the circular base 85 and the nut 2. When the anchoring nail 1 is screwed into the gum, the circular base 85 abuts against the gum, preventing the bottom side of the nut 2 from directly contacting the gum, which facilitates the flow of food at the bottom. The nut of the filling nail 86 is cylindrical and is screwed into the empty threaded hole 81, which just fills the gap and prevents food from being retained.

[0048] During use, the traction direction can be adjusted at will by rotating the extension rod 433 on the universal ball head 42, making it more suitable for dentists to operate; by passing the rubber band or binding wire through the threaded hole 2 5, the practicality of the device can be improved, thus adapting to different patients; by screwing the screw 3 82 into the threaded hole, the connection method of the hook can be increased, which is more traditional but has high stability, further enhancing its practicality.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
