[0028] A common treatment method in clinical practice is to set two adjustment plates, one of which is used to be fixedly fitted on the teeth on one side, and the other is used to be fixedly fitted on the teeth on the other side. After installation, the teeth are pushed and adjusted by adjusting the gap between the two adjustment plates to achieve correction. However, in the current use process, after the adjustment plate is manufactured, its overall structure is a rigid structure, and medical staff cannot adjust the adjustment plate again according to the treatment plan, and it lacks flexibility. In view of the above technical problems, the utility model provides a medical movable correction device, which can flexibly achieve expansion adjustment or contraction adjustment according to the treatment plan, and has the advantage of high flexibility in use. The technical solution of the utility model is described in detail below with reference to specific examples.
[0029] Reference Figure 1 as well as Figure 2 As shown, the utility model relates to a medical movable correction device, comprising a first adjustment piece 1, a second adjustment piece 2 and an adjustment assembly. The first adjustment piece 1 and the second adjustment piece 2 both have a fitting area 3 for fitting on teeth.
[0030] The adjustment assembly includes a first mounting member 4 and a second mounting member 5, wherein the first mounting member 4 is arranged on the first adjustment piece 1, and the second mounting member 5 is arranged on the second adjustment piece 2. The first mounting member 4 is provided with a slide bar 6, which passes through the second mounting member 5 and is slidably connected with the second mounting member 5. The first mounting member 4 is also provided with an adjustment bolt 7, one end of which is rotatably connected with the first mounting member 4, and the other end is threadedly connected with the second mounting member 5, and the axes of the slide bar 6 and the adjustment bolt 7 are parallel to each other.
[0031] In addition, a through slot 8 is provided on the first adjusting piece 1 , the first mounting member 4 is movably provided on the first adjusting piece 1 , and a locking structure for limiting the movement of the first mounting member 4 is provided on the first adjusting piece 1 .
[0032] It should be noted that, in this embodiment, the fitting area 3 of the first adjustment piece 1 and the second adjustment piece 2 is specifically a part for the patient to fit on the teeth. In the early manufacturing process, the shape of the fitting area 3 is determined according to the formulated treatment plan, so that the first adjustment piece 1 and the second adjustment piece 2 can fit on the patient's teeth when worn, thereby realizing the installation and fixation of the first adjustment piece 1 and the second adjustment piece 2.
[0033] For example, when the correction device is used, the first adjustment piece 1 and the second adjustment piece 2 are inserted onto the patient's teeth through the fitting area 3, and then the distance between the first adjustment piece 1 and the second adjustment piece 2 is adjusted by rotating the adjustment bolt 7 to achieve the purpose of correction. During the correction process, the expansion adjustment or contraction adjustment between the first adjustment piece 1 and the second adjustment piece 2 can be flexibly achieved by rotating the adjustment bolt 7 in the forward or reverse direction.
[0034] In addition, since the first mounting member 4 is integrally movably arranged on the first adjusting piece 1, and a locking structure for limiting the movement of the first mounting member 4 is arranged on the first adjusting piece 1, even if the first adjusting piece 1 and the second adjusting piece 2 are rigid structures after manufacturing, during use, the medical staff can still adjust the adjusting piece again according to the treatment plan. When adjusting, it is only necessary to loosen the fixing restriction of the locking structure on the first mounting member 4, and then the position of the first mounting member 4 can be adjusted according to the treatment plan. After the adjustment is completed, since the second mounting member 5 is an integrally fixed structure, in the early stage of the adjustment, when the fitting area 3 on the second adjusting piece 2 is inserted into the patient's teeth, there will be an initial discomfort. After gradually wearing and correcting, the fitting area 3 of the second adjusting piece 2 fits with the patient's teeth again to achieve correction. In this process, the medical staff can adjust the position of the first mounting member 4 again through the locking structure according to the needs, and the medical staff needs to consider whether the deformation amount in the correction stage fits the staged correction plan.
[0035] In one embodiment, it is more preferred that, in order to optimize the guiding stability of the device, two slide bars 6 are provided and are arranged parallel to each other. Specifically, the two slide bars 6 are mirror-imaged on both sides of the adjusting bolt 7. When the adjusting bolt 7 is rotated for adjustment, the two slide bars 6 can well guide the force of the adjusting bolt 7 located in the middle, and can improve the overall force balance of the device. In this embodiment, the slide bar 6 has a connecting end, and the connecting end is sunk into the first mounting member 4 to prevent the connecting end from protruding and interfering with the patient's rotation of the adjusting bolt 7.
[0036] In one embodiment, more preferably, a limiting member 9 is threadedly connected to the end of the sliding rod 6 , and the limiting member 9 limits the sliding rod 6 from sliding away from the second mounting member 5 .
[0037] It should be noted that the setting of the limiter 9 can limit the expansion distance between the first adjustment piece 1 and the second adjustment piece 2. When the medical staff adjusts and installs the device, the adjustment distance between the first adjustment piece 1 and the second adjustment piece 2 can be obtained according to the treatment plan. During the subsequent correction process, the patient needs to turn the adjusting bolt 7 according to the doctor's instructions for correction. In order to serve as a reminder to the patient, the medical staff can adjust the specific position of the limiter 9 according to the adjustment distance between the first adjustment piece 1 and the second adjustment piece 2. When the specified expansion distance between the first adjustment piece 1 and the second adjustment piece 2 is completed, the limiter 9 can limit the first adjustment piece 1 and the second adjustment piece 2 from continuing to expand, and the patient cannot turn the adjusting bolt 7, thereby achieving the reminder effect.
[0038] In one embodiment, the locking structure is further refined, and the locking structure includes a through slot 8, a locking bolt 10, and a limiting slot 11, wherein the through slot 8 is provided on the first adjustment plate 1. The locking bolt 10 is movably arranged in the through slot 8, one end of the locking bolt 10 is threadedly connected to the first mounting member 4, and the other end is a limiting end, and the limiting slot 11 is provided on the side of the through slot 8 that is back to the first mounting member 4, and the limiting end is clamped in the limiting slot 11. Specifically, in order to prevent the limiting end from protruding and causing scratches on the patient's cavity, the limiting end is sunk into the limiting slot 11.
[0039] For example, when the position of the first mounting member 4 needs to be adjusted, the position adjustment can be performed by loosening the locking bolt 10. After the first mounting member 4 is adjusted to the desired position, the locking bolt 10 is tightened again, and the limiting end of the locking bolt 10 is clamped in the limiting groove 11, so that the first mounting member 4 is repositioned and fixed.
[0040] During the adjustment process, it should be noted that since the first mounting member 4 is positioned and fixed as a whole by the locking bolt 10, when the position of the first mounting member 4 is adjusted, the locking bolt 10 will also limit the displacement of the first mounting member 4. The first mounting member 4 can be adjusted along the length direction of the through groove 8, and the rotation angle can also be adjusted along the axial direction of the locking bolt 10.
[0041] In this embodiment, specifically, the through slot 8 can be configured as a straight line or an arc. At the same time, in order to improve the overall fixing stability, two locking bolts 10 are provided.
[0042] Among them, the arc-shaped through groove 8 structure can achieve angle adjustment of the first mounting member 4 even if two locking bolts 10 are provided, and the overall adjustment method is more flexible.
[0043] In an extended embodiment, a through groove 8 is also provided on the second adjustment plate 2, and the second mounting member 5 is also adjustably connected to the second adjustment plate 2 through a locking structure. In this embodiment, the first mounting member 4 and the second mounting member 5 can both be adjusted in position according to actual needs, and their adjustability is higher.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
