Description

Technical Field

[0001] This utility model relates to the field of oral technology, and in particular to a novel square wire archetype for orthodontic use. Background Technology

[0002] In orthodontic treatment, the square wire archetype is an important auxiliary tool. It is mainly used to bend a straight stainless steel square wire into a U-shaped structure that conforms to the arc shape of a normal human dental arch, so that it can be placed into the brackets bonded to the tooth surface in the mouth, thereby playing a role in straightening teeth.

[0003] However, traditional square wire archetypes require the operator to first place the stainless steel wire into the corresponding groove of the archetype, then hold one end of the archetype with one hand and use the fingertips to press down on the middle of the archwire, while using the other hand to fix one end of the stainless steel wire with the pressure bar, and repeatedly rotate the archetype in both directions until the straight stainless steel wire is bent into the desired U-shaped dental arch shape. For beginners, because the shaft of the traditional square wire archetype is round, it is easy to over-bend the archwire when rotating the pressure bar, making it difficult to form a natural U-shaped dental arch. This results in time-consuming, laborious, and material-intensive operation. Therefore, this utility model proposes a new type of square wire archetype for orthodontics to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of square wire archetype for orthodontics.

[0005] To achieve the above objectives, this utility model provides a novel square wire archetype for orthodontic use, comprising a base plate and an archetype. Side plates are fixedly mounted on both sides of the top of the base plate, and a fixed shaft is fixedly installed between the two side plates. Several sleeves are sleeved on the fixed shaft, and an archetype block is fixedly mounted on the top of each sleeve. The curvature of the archetype block is adjustable, and a groove is formed through the top of the archetype block. A straight square wire is clamped at the center of the top of the groove. Two archetypes are provided, each with an inverted T-shaped structure. Each archetype includes a handle, and a base block is fixedly mounted on the bottom of the handle. A concave groove is formed through the bottom of the base block, and the two base blocks are movably clamped onto the front and rear sides of the archetype block through the concave groove.

[0006] Furthermore, a support plate is provided below the base plate, and vertical plates are fixedly provided on both sides of the top of the support plate, with the top of the vertical plates fixedly provided on the top of the base plate.

[0007] Furthermore, adjustment plates are rotatably provided on the front and rear sides of the bottom of the molding block, and the bottom of both adjustment plates is fixedly connected to the connecting rod. A threaded rod is fixedly provided on the bottom of the connecting rod. A through hole is provided through the top of the base plate. The threaded rod passes through the through hole and extends downward. A nut is threaded on the threaded rod. The nut is located below the base plate and above the support plate.

[0008] Furthermore, a pressure bar is provided above the molding block, the pressure bar is installed between the two side plates, the longitudinal section of the pressure bar is rectangular, and the pressure bar is made of aluminum alloy.

[0009] Furthermore, each end of the pressure rod has a horizontal groove, an electric push rod is fixedly installed inside the groove, and a locking block is fixedly installed at the telescopic end of the electric push rod. The locking block is located in the groove, and the inner walls of the two side plates have slots, and the locking block is locked in the slots.

[0010] Furthermore, a pressure sensing plate is fixedly provided on the side of the card block away from the electric push rod. The pressure sensing plate is electrically connected to the pressure controller, and the pressure controller is electrically connected to the electric push rod.

[0011] Furthermore, the outer side of the handle is provided with anti-slip texture, and the molded block is arc-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves inserting a straight square wire into the center of a groove on the top of a molding block. The groove is designed to accommodate square wires of different thicknesses to meet various specifications. The operator holds two molding devices, and the bottom block of each molding device is movably locked onto the front and rear sides of the molding block through a concave groove. The square wire is located in the concave groove, and pressure is applied along the arc surface of the molding block to form the square wire into the desired U-shaped form in one go.

[0014] 2. This utility model adjusts the pressure rod to a suitable position so that it covers the square wire. When the electric push rod is activated to extend, it drives the locking block to move into the slot. The pressure sensor detects the pressure in real time. When the pressure sensor detects the pressure, the pressure controller controls the electric push rod to stop extending. At this time, the locking block is locked in the slot. Conversely, when the electric push rod is activated to retract, the locking block can be dislodged from the slot. The pressure rod is easy to install and remove. Pressing down on the pressure rod presses down on the square wire, making it easy to lock the square wire into the groove.

[0015] 3. This utility model, based on the required opening and closing degree of the U-shaped dental arch, uses a threaded rod in conjunction with a threaded nut. When the nut is rotated, the threaded rod moves up and down, causing the connecting rod and adjusting plate to move up and down, thereby changing the curvature of the forming block.

[0029] Please see Figure 1-8 A novel orthodontic square wire archetype includes a base plate 5 and an archetype 18. Side plates 1 are fixedly mounted on both sides of the top of the base plate 5, and a fixing shaft 4 is fixedly installed between the two side plates 1. Several sleeves 8 are fitted onto the fixing shaft 4, and an arching block 2 is fixedly mounted on the top of each sleeve 8. The arching block 2 is arc-shaped and its curvature is adjustable. A support plate 7 is located below the base plate 5, and vertical plates 6 are fixedly mounted on both sides of the top of the support plate 7. The top of the vertical plates 6 is fixedly mounted on the top of the base plate 5. Adjustable joints are rotatably mounted on the front and rear sides of the bottom of the arching block 2. Plate 20, the bottom of both adjusting plates 20 are fixedly connected to connecting rod 21, and a threaded rod 10 is fixedly installed at the bottom of connecting rod 21. A through hole 11 is opened through the top of the base plate 5, and the threaded rod 10 passes through the through hole 11 and extends downward. A nut 9 is threaded on the threaded rod 10. The nut 9 is located below the base plate 5 and above the support plate 7. According to the opening degree of the required U-shaped tooth arch shape, it is engaged with the threaded rod 10 through the thread. When the nut 9 is rotated, the threaded rod 10 moves up and down, driving the connecting rod 21 and adjusting plate 20 to move up and down, thereby changing the curvature of the forming block 2.

[0030] The top of the molding block 2 is provided with a groove 3. A straight square wire 19 is inserted into the center of the top of the groove 3. The straight square wire 19 is inserted into the groove 3 at the top of the molding block 2 to ensure that the center of the square wire 19 is aligned with the center line of the groove 3. The size design of the groove 3 can accommodate square wires of different thicknesses to meet the needs of various specifications.

[0031] As an improvement to the above technical solution, a pressure rod 13 is provided above the molding block 2. The pressure rod 13 is installed between the two side plates 1. The longitudinal section of the pressure rod 13 is rectangular. The pressure rod 13 is made of aluminum alloy. The two ends of the pressure rod 13 are respectively provided with grooves 15 laterally. The grooves 15 make the outer side of the pressure rod 13 open. An electric push rod 14 is fixedly installed inside the groove 15. A locking block 17 is fixedly installed at the telescopic end of the electric push rod 14. The locking block 17 is located in the groove 15. The inner walls of the two side plates 1 are respectively provided with slots 12. The locking block 17 is locked in the slots 12. A pressure sensing plate 16 is fixedly installed on the side of the locking block 17 away from the electric push rod 14. The pressure sensing plate 16 is electrically connected to the pressure controller, and the pressure controller is electrically connected to the electric push rod 14.

[0032] In use, adjust the pressure rod 13 to a suitable position so that it covers the square wire 19. Activate the electric push rod 14 to extend it. The electric push rod 14 drives the locking block 17 to move into the locking groove 12. The pressure sensing element 16 senses the pressure in real time. When the pressure sensing element 16 senses pressure, the pressure controller controls the electric push rod 14 to stop extending. At this time, the locking block 17 is locked in the locking groove 12. Conversely, activating the electric push rod 14 to retract it allows the locking block 17 to detach from the locking groove 12. The pressure rod 13 is easy to install and remove. Pressing down on the pressure rod 13 presses down on the square wire 19, making it easy to lock the square wire 19 into the groove 3. The pressure controller of this utility model uses a conventional micro controller available on the market. The pressure sensing element 16 also uses a commercially available thin-film pressure sensor or pressure sensing structure, currently used for pressure detection; further details are omitted.

[0033] As an improvement to the above technical solution, see [link to relevant documentation]. Figure 6 and Figure 8 There are two molding devices 18. The molding device 18 has an inverted T-shaped structure and includes a handle 181. The outer side of the handle 181 is provided with anti-slip texture to facilitate the operator's grip.

[0034] A base block 182 is fixedly installed at the bottom of the handle 181. A concave groove is provided through the bottom of the base block 182. The two base blocks 182 are movably locked on the front and rear sides of the forming block 2 through the concave groove 22. The operator holds two forming devices 18. The base block 182 of each forming device 18 is movably locked on the front and rear sides of the forming block 2 through the concave groove 22. The square wire 19 is located in the concave groove 22. Pressure is applied along the arc surface of the forming block 2 to form the square wire 19 into the required U-shaped shape in one go.

[0035] The working principle and usage of this utility model:

[0036] In use, insert the straight square wire 19 into the groove 3 on the top of the forming block 2, ensuring that the center of the square wire 19 is aligned with the center line of the groove 3. The groove 3 is designed to accommodate square wires of different thicknesses to meet various specifications. Adjust the pressure rod 13 to a suitable position so that it covers the square wire 19. Activate the electric push rod 14 to extend, which drives the locking block 17 to move into the locking slot 12. The pressure sensor 16 senses the pressure in real time. When the pressure sensor 16 senses pressure, the pressure controller controls the electric push rod 14 to stop extending. At this time, the locking block 17 is locked in the locking slot 12. Conversely, activate the electric push rod 14 to retract, and the locking block 17 can be released from the groove. The card slot 12 is dislodged, and the pressure rod 13 is easy to install and disassemble. Pressing down on the pressure rod 13 presses down on the square wire 19, making it easy to insert the square wire 19 into the groove 3. According to the required opening degree of the U-shaped tooth arch shape, it is connected to the threaded rod 10 through the thread. When the nut 9 is rotated, the threaded rod 10 moves up and down, driving the connecting rod 21 and the adjusting plate 20 to move up and down, thereby changing the curvature of the forming block 2. The operator holds two forming devices 18. The bottom block 182 of each forming device 18 is movably locked on the front and rear sides of the forming block 2 through the concave groove 22. The square wire 19 is located in the concave groove 22. Pressure is applied along the arc surface of the forming block 2, so that the square wire 19 is formed into the required U-shaped shape in one go.
