Description

Technical Field

[0001] This utility model relates to a medical device for oral use, and more particularly to a machine-made rubber polishing strip and its orthodontic proximal surface enamel removal machine. Background Technology

[0002] Interproximal enamel removal, like tooth extraction, arch expansion, and molar distalization, is done to create space for teeth to move. It typically involves using a diamond strip to grind away a small portion of the adjacent area between teeth to create space. This gap is then closed using orthodontic treatment. After enamel removal, the surface needs to be polished and treated with fluoride or desensitizing agents to prevent cavities and tooth sensitivity.

[0003] In existing technologies, polishing abrasive strips are often used to polish the surface of teeth that have had their enamel removed. Because the material of the polishing abrasive strips is relatively hard, polishing the surface of teeth that have had their enamel removed requires a high level of skill from the dentist. If the force is slightly too great or the time is slightly too long, it will lead to over-polishing, which will cause too much of the tooth surface to be worn away. As a result, the tooth loses the protection of the enamel and is more prone to decay. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a machine-use rubber polishing strip and its orthodontic proximal surface glaze removal machine.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A machine-grade rubber polishing strip includes an arc-shaped retainer and a connecting handle. One end of the connecting handle is connected to one end of the arc-shaped retainer, and a sheet-cut rubber polishing strip is disposed between the two ends of the arc-shaped retainer.

[0007] As a preferred embodiment of this utility model, a retaining pin is provided at one end of the sheet-cut rubber polishing strip, and a retaining plate is provided at the other end of the sheet-cut rubber polishing strip. Both the retaining pin and the retaining plate extend out from the corresponding sides of the sheet-cut rubber polishing strip.

[0008] As a preferred embodiment of this utility model, the front end side plate of the bow-shaped retaining frame is provided with a slot I for the retaining pin to be engaged, and the front end plate is provided with a sliding plate for retaining the retaining pin.

[0009] As a preferred embodiment of this utility model, a sliding groove is provided on the front plate surface, and the sliding plate is disposed in the sliding groove and slides in cooperation with the sliding groove.

[0010] As a preferred embodiment of this utility model, a magnetic strip is provided on the side of the slide groove near the sheet-cut rubber polishing strip to attract the sliding slide plate.

[0011] As a preferred embodiment of this utility model, the retaining plate is provided with a toothed rack I with concave and convex shapes; the rear end side plate of the bow-shaped retaining frame is provided with a slot II for the retaining plate to be inserted into and for the retaining plate to be slidably adjusted, and the rear end plate is also provided with a rotatable positioning plate, the positioning plate being provided with a toothed rack II with concave and convex shapes, when the positioning plate covers the retaining plate, the toothed rack II on the positioning plate and the toothed rack I on the retaining plate engage.

[0012] As a preferred embodiment of this utility model, a rotating shaft is provided on the side of the slot II near the connecting handle, and torsion springs are respectively sleeved on the rotating shaft near both sides. One end of the positioning plate is sleeved on the rotating shaft, one end of the torsion spring is connected to the side wall of the corresponding slot II, and the other end of the torsion spring is connected to the rotating shaft. When the torsion spring is in its natural state, the positioning plate covers the retaining plate.

[0013] As a preferred embodiment of this utility model, a hook I is provided on the side of the retaining plate away from the sheet-cut rubber polishing strip; an adjustment hole is provided on the rear side plate, the adjustment hole is located below the rotating shaft, an adjustment rod is provided in the adjustment hole, one end of the adjustment rod extends into the slot II, the other end of the adjustment rod extends out of the outer side of the rear side plate and is close to the connecting handle, and a hook II that can be connected to the hook I is provided on the end of the adjustment rod that extends into the slot II.

[0014] In a preferred embodiment of this utility model, the adjusting hole is a threaded hole, the adjusting rod is a threaded adjusting rod, the adjusting rod is threadedly engaged with the adjusting hole, and the hook II is rotatably engaged with the adjusting rod.

[0015] The orthodontic proximal surface glazing machine includes a bending head housing component and the aforementioned machine rubber polishing strip, with the other end of the connecting handle inserted into the shaft core component in the bending head housing component.

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

[0017] 1. This utility model uses a slab-cut rubber polishing strip. Compared with polishing abrasive strips, the slab-cut rubber polishing strip is made of a softer material. When polishing the surface of teeth that has been ground down by enamel removal, if the force is slightly too great, the slab-cut rubber polishing strip has a certain degree of elasticity. The elasticity will buffer the slight over-polishing and prevent over-polishing, thus effectively protecting the enamel of the teeth and preventing tooth decay. It also reduces the skill requirements for the dentist.

[0018] 2. This utility model has a slot I on one side of the front end plate of the bow-shaped retaining frame and a slot II on one side of the rear end plate. The retaining pin of the sliced ​​rubber polishing strip is locked in slot I, the retaining plate is placed in slot II, the sliding plate is pushed to cover the retaining pin, and the positioning plate is rotated to cover the retaining plate, so the sliced ​​rubber polishing strip can be installed in place. When disassembling, only the sliding plate needs to be pushed and the positioning plate rotated. Therefore, the installation and disassembly of the sliced ​​rubber polishing strip is extremely convenient.

[0019] 3. After the retaining plate is placed in the slot II, rotate the positioning plate outward and rotate the adjusting rod to adjust the position of the retaining plate in the slot II, thereby adjusting the tightness of the sheet-cut rubber polishing strip. After adjustment, put the positioning plate down to fix the position of the retaining plate. The tightness of the sheet-cut rubber polishing strip is easy to adjust. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 As shown, the machine-use rubber polishing strip includes an arc-shaped retainer 1 and a connecting handle 2. One end of the connecting handle 2 is connected to one end of the arc-shaped retainer 1, and a sliced ​​rubber polishing strip 3 is disposed between the two ends of the arc-shaped retainer 1. In this embodiment, the front end of the connecting handle 2 is connected to the rear side of the rear end of the arc-shaped retainer 1, the front end of the sliced ​​rubber polishing strip 3 is connected to the front end of the arc-shaped retainer 1, and the rear end of the sliced ​​rubber polishing strip 3 is connected to the rear end of the arc-shaped retainer 1. In this embodiment, the front end refers to the side facing into the oral cavity during operation, and the rear end refers to the side away from the cavity.

[0038] The front end of the sheet-cut rubber polishing strip 3 is provided with a retaining pin 4, and the rear end of the sheet-cut rubber polishing strip 3 is provided with a retaining plate 5. Both the retaining pin 4 and the retaining plate 5 extend out from the corresponding sides of the sheet-cut rubber polishing strip 3. Figure 2 As shown, the retaining plate 5 is provided with multiple toothed racks I51 with concave and convex shapes, and a hook I52 is provided on the side of the retaining plate 5 away from the sheet-cut rubber polishing strip 3 (that is, a hook I52 is provided on the rear side of the retaining plate 5).

[0039] The front side plate 6 of the bow-shaped retainer 1 is provided with a slot I 61 for the retaining pin 4 to be engaged. The front plate 6 is provided with a sliding groove 62, and the slot I 61 is disposed in the sliding groove 62. Figure 3As shown. A sliding plate 7 is provided on the front end plate 6 to secure the retaining pin 4. The sliding plate 7 is disposed within the sliding groove 62 and slides in cooperation with the sliding groove 62, as shown. Figure 4 As shown. A magnetic strip 63 is provided inside the groove 62 near the side of the sheet-cut rubber polishing strip 3 to attract the sliding plate 7, as shown. Figure 3-5 As shown. In this embodiment, a guide groove 64 is provided on the side wall of the groove 62, and a strip-shaped limiting groove 65 is also provided in the groove 62. The length direction of the limiting groove 65 is the same as the length direction of the sheet-cut rubber polishing strip 3, as shown. Figure 6 and Figure 7 As shown. The side wall of the slide plate 7 is provided with a guide rail 71 that mates with the guide groove 64, and the slide plate 7 is provided with a limiting rail 72 that mates with the limiting groove 65, as shown. Figure 8 As shown. The slide plate 7 is installed in the slide groove 62. The guide slide rails 71 on both sides of the slide plate 7 are located in the corresponding guide slide grooves 64 and slide in cooperation with the corresponding guide slide grooves 64. The limiting slide rail 72 on the slide plate 7 is located in the limiting slide groove 65 and slides in cooperation with the corresponding limiting slide groove 65. When the slide plate 7 is pushed forward (i.e., away from the direction of the sheet-cut rubber polishing strip 3), the retaining pin I 61 is exposed. At this time, the retaining pin 4 at the front end of the sheet-cut rubber polishing strip 3 can be locked in the retaining pin I 61, as shown. Figure 9 As shown, after pushing the slide plate 7 to the rear (i.e., towards the direction of the sheet-cut rubber polishing strip 3), the slide plate 7 covers the retaining pin 4, preventing the retaining pin 4 from exiting the slot I 61. Due to the limiting effect of the guide groove 64, the slide plate 7 stops sliding when it reaches the rear side of the groove 62. The slide plate 7 can be made of metal or a material that attracts the magnetic strip 63. When the slide plate 7 moves to the rear side of the groove 62, it facilitates the attraction of the magnetic strip 63. The position of the slide plate 7 is restricted on the groove 62 by attraction. Figure 1 As shown.

[0040] The rear side plate 8 of the bow-shaped retainer 1 is provided with a slot II 81 for the retaining plate 5 to be inserted into and for the retaining plate 5 to be slidably adjusted. Figure 10 As shown. A rotatable positioning plate 9 is also provided on the rear end plate 8. The positioning plate 9 is equipped with a toothed rack II 91 with concave and convex shapes, as shown. Figure 11 As shown, when the positioning plate 9 covers the retaining plate 5, the protruding and recessed rack II 91 on the positioning plate 9 and the protruding and recessed rack I 51 on the retaining plate 5 engage, as shown. Figure 1 As shown.

[0041] In this embodiment, a rotating shaft 82 is provided on the side of the card slot II 81 near the connecting handle 2, such as... Figure 12 As shown, the two ends of the rotating shaft 82 are rotatably engaged with the two side walls of the slot II 81. Torsion springs 83 are respectively fitted onto the rotating shaft 82 near both sides, as shown... Figure 10As shown. One end of the positioning plate 9 is fitted onto the rotating shaft 82, one end of the torsion spring 83 is connected to the side wall of the corresponding slot II 81, and the other end of the torsion spring 83 is connected to the rotating shaft 82, as shown. Figure 10 As shown, when the torsion spring 83 is in its natural state, the positioning plate 9 covers the retaining plate 5, as... Figure 1 As shown. An adjustment hole 84 is provided on one side of the rear panel 8, located below the rotating shaft 82, as shown. Figure 13 As shown, an adjusting rod 85 is provided in the adjusting hole 84. One end of the adjusting rod 85 extends into the slot II 81, and the other end of the adjusting rod 85 extends outward from the outer side of the rear end plate 8 and is close to the connecting handle 2. A hook II 86 that can be connected to the hook I 52 is provided on the end of the adjusting rod 85 that extends into the slot II 81. Figure 14 As shown. The adjusting hole 84 is a threaded hole, the adjusting rod 85 is a threaded adjusting rod, the adjusting rod 85 is threadedly engaged with the adjusting hole 84, and the hook II 86 is rotatably engaged with the adjusting rod 85.

[0042] This utility model uses a slab-cut rubber polishing strip 3. Compared with polishing abrasive strips, the slab-cut rubber polishing strip 3 is made of a softer material. When polishing the surface of the tooth after enamel removal, if the force is slightly too great, the slab-cut rubber polishing strip 3 has a certain degree of elasticity. The elasticity will buffer the slight over-polishing, avoid over-polishing, effectively protect the enamel of the tooth, and thus prevent tooth decay. It also reduces the skill requirements for the dentist. As the polishing time of the sheet-cut rubber polishing strip 3 increases, the length of the sheet-cut rubber polishing strip 3 may increase, meaning that the sheet-cut rubber polishing strip 3 on the bow-shaped retaining frame 1 may become slightly loose. At this time, the positioning plate 9 can be rotated outward, and the adjusting rod 85 can be rotated. The adjusting rod 85 will drive the retaining plate 5 on the rear side of the sheet-cut rubber polishing strip 3 to move backward in the slot II 81, thereby adjusting the position of the retaining plate 5 in the slot II 81 and thus adjusting the tightness of the sheet-cut rubber polishing strip 3. After adjustment, the positioning plate 9 can be lowered to fix the position of the retaining plate 5. The adjustment of the tightness of the sheet-cut rubber polishing strip 3 is extremely convenient.

[0043] This invention features a slot I 51 on one side plate 6 at the front end of the bow-shaped retaining frame 1 and a slot II 81 on one side plate 8 at the rear end. The retaining pin 4 at the front end of the sliced ​​rubber polishing strip 3 is engaged in slot I 51, and the retaining plate 5 at the rear end of the sliced ​​rubber polishing strip 3 is placed in slot II 81. The sliding plate 7 is pushed to cover the retaining pin 4, and the positioning plate 9 is rotated to cover the retaining plate 5, thus allowing the sliced ​​rubber polishing strip 3 to be installed between the two ends of the bow-shaped retaining frame 1. Disassembly is extremely convenient; simply push the sliding plate 7 forward and rotate the positioning plate 9 outward to remove the sliced ​​rubber polishing strip 3 from the bow-shaped retaining frame 1. In addition to installing the slicing rubber polishing strip 3, the bow-shaped retaining frame 1 of this utility model can also install diamond abrasive strips or polishing abrasive strips. Simply set retaining pins 4 and retaining plates 5 at both ends of the diamond abrasive strip or polishing abrasive strip, and the two ends of the diamond abrasive strip or polishing abrasive strip can be installed on both ends of the bow-shaped retaining frame 1 of this utility model. It can be switched for use as needed.

[0044] The orthodontic proximal surface enamel removal machine includes a curved head housing component 10 and a machine-use rubber polishing strip. The other end of the connecting handle 2 is inserted into the shaft core component in the curved head housing component 10, such as... Figure 15 As shown, the curved head housing component 10 and the shaft core component are both existing technologies, so they will not be described in detail here. Please refer to the patent publication number CN 221106063U, which discloses the technical content of a dental proximal enamel removal curved head.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
