Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a novel longitudinal and transverse transduction magnetic attraction force arch expander. Background Art

[0002] The expander is a common orthodontic device, usually installed in the maxillary palate, used to push the bilateral dental arches outward to expand, thereby expanding the arch curvature and solving common malocclusion problems such as crowded teeth and narrow arches. Based on the traditional mechanical expander, magnetic expanders have gradually been used in recent years. They usually apply expansion force to achieve the purpose of correction through the repulsive force generated between the magnets set on both sides of the dental arch.

[0003] However, the existing magnetic bow expansion device still has the following significant shortcomings:

[0004] The magnet is large and the device has poor adaptability: Existing magnetic expanders usually rely on larger magnetic blocks to obtain sufficient expansion force. However, in the case of severely narrow dental arches, the large size of the appliance can easily lead to difficulties in placement due to limited space in the oral cavity, seriously affecting its clinical adaptability and promotion and application.

[0005] Unstable repulsive force direction, unbalanced correction force: Repulsive magnetic expanders have obvious lateral force components during use, especially when the distance between the magnets is close and the repulsive force is enhanced, the lateral force can easily break the balance of the device, causing deformation of the device, stagnation of the sliding guide rail, and even expansion failure. This type of unbalanced expansion device is not only difficult to achieve uniform force application, but may also cause adverse reactions such as tooth displacement, loosening, and pain, affecting the patient's comfort and treatment prognosis.

[0006] The force decays quickly and lacks continuous correction ability: As the expansion process progresses, the distance between the magnets gradually increases, and the repulsive force decays sharply, making it difficult to maintain the constant force required for effective expansion, which significantly limits the continuous effect and scope of application of magnetic expansion.

[0007] Uneven expansion, poor effect in the posterior area: Traditional expanders, including spiral expanders and repulsive magnetic expanders, often have an expansion mode of "wide in front and narrow in the back" during maxillary expansion. Since the resistance in the front section is small and the resistance in the back section is large, the expansion force is unevenly distributed, resulting in insufficient expansion in the posterior area, which is precisely the key area for clinical treatment of maxillary stenosis, making it difficult to achieve ideal correction results.

[0008] In summary, the existing magnetic expanders have problems such as poor adaptability, insufficient mechanical stability, weak individual adjustment ability and easy attenuation of correction force. There is an urgent need for a new magnetic expander with a compact structure, controllable force direction, strong adaptability and high correction efficiency to overcome the limitations of existing technology and meet the clinical needs of precise, controllable and safe expansion treatment. Summary of the invention

[0009] Based on this, the purpose of the present invention is to provide a new type of longitudinal and transverse transfer magnetic attraction force expander, which adopts magnetic attraction force instead of traditional repulsion force, so as to overcome the problem of traditional expanders that as the dental arch expands, the distance between magnets increases and the magnetic force decreases sharply; at the same time, by setting the direction of the magnetic force perpendicular to the expansion direction of the dental arch, the new type of longitudinal and transverse transfer magnetic attraction force expander can match larger magnets to meet the demand for greater magnetic force, so that the magnet can move in a direction perpendicular to the expansion direction of the dental arch and has a larger activity space.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] See also Figure 1 and Figure 2The embodiment of the present application provides a novel longitudinal and transverse transfer magnetic force expander, which is connected to dental band rings on both sides to push the dental arches on both sides to expand outward. The magnetic force expander includes: a magnetic base body 10 and at least one set of expansion mechanism 20, the magnetic base body 10 includes two magnetic bases arranged at intervals, and the polarities of the two magnetic bases close to each other are attracted. The expansion mechanism 20 includes a base and a translation assembly, and the translation assembly includes at least one push rod, one end of the push rod is rotatably connected to the base, and the other end is rotatably connected to one of the magnetic bases. When the magnetic base moves due to the magnetic force, the push rod is driven to deflect, so that the push rod pushes the base outward.

[0045] In some embodiments, the translation assembly includes a push rod. In this setting, the magnetic expander is also provided with a vertical positioning member, which includes a first vertical portion and a second vertical portion that are vertically arranged. The base is slidably connected to the first vertical portion, and the magnetic base is slidably connected to the second vertical portion to limit the running direction of the base to be perpendicular to the running direction of the magnetic base.

[0046] Preferably, the translation assembly includes two push rods arranged at a certain angle, one end of the two push rods is close to each other and rotatably connected to the base, and the other end is rotatably connected to two magnetic seats, so that the magnetic attraction generated by the two magnetic seats drives the push rods to push the base to translate toward the outside. In this arrangement, the force of the push rods on the base is more balanced, and it is easy to ensure that the base translates perpendicular to the direction of the magnetic attraction.

[0047] In some other embodiments, the translation assembly may further include a plurality of cross-pivoted push rods, but is not limited thereto.

[0048] It can be understood that in some embodiments, the expansion mechanism 20 can be arranged as a group. In this arrangement, the tooth band ring on one side is fixed to the base, and the tooth band ring on the other side is fixed to the magnetic base body 10. The magnetic attraction force is generated by the two magnetic bases, and the two magnetic bases are close to each other, and then the push rod is driven to push the base outward, so that the distance between the base and the magnetic base body 10 is increased, thereby pushing the dental arches on both sides to expand outward.

[0049] In some other embodiments, the spreading mechanism 20 can be set as two groups, and the opening and closing directions of the two bases are perpendicular to the magnetic attraction directions of the two magnetic bases. In this setting, the tooth band rings on both sides are fixed to the bases on both sides respectively, and the two magnetic bases are approached to each other through the magnetic attraction generated by the two magnetic bases, and then the push rod is driven to push the two bases outward respectively, so that the two bases are away from each other, thereby pushing the dental arches on both sides to expand outward.

[0050] The novel longitudinal and transverse transfer magnetic attraction force expander provided in the embodiment of the present application adopts magnetic attraction force instead of traditional repulsion force, which can effectively overcome the problem of traditional magnetic expanders that the magnetic force decreases sharply as the distance between magnets increases as the dental arch expands; at the same time, by setting the direction of the magnetic force perpendicular to the direction of dental arch expansion, the magnetic attraction force expander can match larger magnets to meet the demand for greater magnetic force. At the same time, the magnet can move in a direction perpendicular to the direction of dental arch expansion, and has a larger activity space.

[0051] As a preferred embodiment, a novel longitudinal and transverse transfer magnetic attraction bow expander includes: a magnetic base body 10, a first base 21 and a second base 22 arranged below the magnetic base body 10, and a first translation assembly 23 and a second translation assembly 24 for supporting the opening and closing of the first base 21 and the second base 22. The magnetic base body 10 includes a first magnetic base 11 and a second magnetic base 12, and the polarities of the ends of the first magnetic base 11 and the second magnetic base 12 that are close to each other are attracted. The opening and closing direction of the first base 21 and the second base 22 is perpendicular to the direction of the magnetic attraction of the first magnetic base 11 and the second magnetic force. The first translation assembly 23 is connected to the magnetic base body 10 and the first base 21, and is used to support the first base 21 outward; the second translation assembly 24 is connected to the magnetic base body 10 and the second base 22, and is used to support the second base 22 outward.

[0052] Furthermore, the first translation assembly 23 includes a first push rod 231 and a second push rod 232 which are arranged at an angle, and one end of the first push rod 231 and the second push rod 232 are simultaneously rotatably connected to the first base 21, and the other ends are respectively rotatably connected to the first magnetic seat 11 and the second magnetic seat 12; the first magnetic seat 11 and the second magnetic seat 12 generate a magnetic attraction force so that the first magnetic seat 11 and the second magnetic seat 12 are close to each other, so that the angle between the first push rod 231 and the second push rod 232 becomes smaller, pushing the first base 21 to an outer side. The second translation assembly 24 includes a third push rod 241 and a fourth push rod 242 which are arranged at an angle. One ends of the third push rod 241 and the fourth push rod 242 are simultaneously rotatably connected to the second base 22, and the other ends are respectively rotatably connected to the first magnetic seat 11 and the second magnetic seat 12. The first magnetic seat 11 and the second magnetic seat 12 generate a magnetic attraction force so that the first magnetic seat 11 and the second magnetic seat 12 are close to each other, so that the angle between the third push rod 241 and the fourth push rod 242 becomes smaller, and the first base 21 is pushed away to the other side.

[0053] As a preferred embodiment, the first translation assembly 23 and the second translation assembly 24 move in the same plane, so that the first base 21 and the second base 22 can be more evenly stressed, avoiding uneven stress on the teeth, causing loose teeth, pain and other adverse symptoms.

[0054] See also Figure 1-3Furthermore, in some embodiments, the opening mechanism 20 further includes a first rotating shaft 25 and a second rotating shaft 26, through which the magnetic base body 10 is connected to the first translation assembly 23 and the second translation assembly 24, so as to realize the motion control of the first base 21 and the second base 22 by the magnetic base body 10. One end of the first rotating shaft 25 is fixed to the first magnetic base 11, and the other end is rotatably connected to the first push rod 231 and the third push rod 241; one end of the second rotating shaft 26 is fixed to the second magnetic base 12, and the other end is rotatably connected to the second push rod 232 and the fourth push rod 242. When the first magnetic seat 11 and the second magnetic seat 12 are attracted by the magnetic force and approach each other, the first push rod 231 and the third push rod 241 rotate around the first rotating shaft 25, so that the angle between the two gradually increases; the second push rod 232 and the fourth push rod 242 rotate around the second rotating shaft 26, so that the angle between the two gradually increases, thereby jointly pushing the first base 21 and the second base 22 outward.

[0055] See also Figure 4-6 Further, in some embodiments, the magnetic base body 10 further includes at least one first guide member 13 for guiding the relative movement of the first magnetic base 11 and the second magnetic base 12 to ensure that the first magnetic base 11 and the second magnetic base 12 are arranged opposite to each other, thereby ensuring the stability of the magnetic attraction. The first guide member 13 is arranged parallel to the magnetic attraction direction of the first magnetic base 11 and the second magnetic base 12, and the first magnetic base 11 and the second magnetic base 12 are both slidably connected to the first guide member 13.

[0056] Specifically, in some embodiments, the first guide member 13 is a slide groove connecting the first magnetic seat 11 and the second magnetic seat 12. The first magnetic seat 11 and the second magnetic seat 12 are slidably disposed in the slide groove. Under the action of magnetic attraction, the two can slide relative to each other.

[0057] Preferably, in the embodiment of the present application, the first guide member 13 is a slide bar, which is slidably inserted into the first magnetic seat 11 and the second magnetic seat 12. Under the action of the magnetic attraction, the two magnetic seats slide relatively along the slide bar. In this arrangement, the volume of the magnetic attraction bow expander can be effectively reduced, and the slide bar is easy to design and install, which is more conducive to ensuring the smoothness of the sliding of the magnetic seat.

[0058] See also Figure 1 , Figure 4 and Figure 5Further, in some embodiments, at least one second guide member 27 is provided between the first base 21 and the second base 22 to guide the movement of the first base 21 and the second base 22 to avoid misalignment and other defects during the movement of the first base 21 and the second base 22. The first base 21 and the second base 22 are slidably connected to the two ends of the second guide member 27. Similarly, the second guide member 27 can be a structural member such as a slide groove, a slide rod, etc. for guiding the linear motion of the first base 21 and the second base 22, which will not be described in detail here.

[0059] Further, in some embodiments, the first magnetic seat 11 includes a first magnet 111 and a first slider 112, and the first slider 112 is fixed inside the first magnet 111; the second magnetic seat 12 includes a second magnet 121 and a second slider 122, and the second slider 122 is fixed inside the second magnet 121; the first slider 112 and the second slider 122 are both provided with a sliding hole 1123, and the first guide member 13 is slidably inserted in the two sliding holes 1123.
