Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an orthodontic rubber chain auxiliary cutting tool. Background Art
[0002] An orthodontic elastic chain is a long, interconnected plastic chain. Because of its chain-like shape, it's called an elastic chain. It's also known as a chain loop or elastic loop. Orthodontic elastic chains are used to stabilize and adjust teeth. When used, they apply force to slowly move teeth, achieving the goal of correcting them. They can also be used to close small gaps, returning teeth to their correct position and correcting misaligned teeth.
[0003] It should be pointed out that in the process of using orthodontic rubber chains for tooth correction, according to the size of the traction force required to be applied to the teeth during correction, orthodontic rubber chains can be divided into three specifications according to the hole spacing: long-distance rubber chain, medium-distance rubber chain, and short-distance rubber chain. The long-distance rubber chain has a hole spacing of approximately 4.0mm, the medium-distance rubber chain has a hole spacing of approximately 3.5mm, and the short-distance rubber chain has a hole spacing of approximately 2.8mm; among them, the shorter the hole spacing of the orthodontic rubber chain, the greater the traction force applied during tooth correction.
[0004] In order to improve the aesthetics of orthodontic treatment, orthodontic elastic bands are generally made of transparent rubber. Orthodontic elastic chains are finished in rolls. Before the patient installs and uses the orthodontic elastic chain, the dental staff needs to cut it according to the required length and determine the cutting position by counting the number of holes in the orthodontic elastic chain. For example, when an orthodontic elastic chain with 8 holes is required, the dental staff counts the 8 holes from the front end of the orthodontic elastic chain and then cuts the orthodontic elastic chain between the 8th and 9th holes.
[0005] It should be pointed out that since orthodontic rubber bands are made of transparent rubber parts and are generally long and thin strips, it is time-consuming for dental medical staff to determine the cutting position by counting the holes, and it is easy for inaccurate hole counting to lead to waste of orthodontic rubber chains. Utility Model Content
[0006] The purpose of the utility model is to provide an orthodontic rubber chain auxiliary cutting tool to address the deficiencies of the existing technology. The orthodontic rubber chain auxiliary cutting tool has a novel structural design, is easy to use, and can effectively improve the efficiency and accuracy of orthodontic rubber chain cutting.
[0007] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.
[0008] An orthodontic rubber chain auxiliary cutting tool includes three rubber chain positioning rulers, each in the shape of a long strip and arranged in sequence from top to bottom. The rear ends of the three rubber chains are pivotally connected by a pivot. The three rubber chain positioning rulers are, from top to bottom, a short-distance positioning ruler suitable for short-distance rubber chains, a medium-distance positioning ruler suitable for medium-distance rubber chains, and a long-distance positioning ruler suitable for long-distance rubber chains.
[0009] The upper surface of each rubber chain positioning ruler is respectively provided with a plurality of positioning protrusions distributed in a linear array along the length direction of the corresponding rubber chain positioning ruler, and the upper surface of the rubber chain positioning ruler is respectively provided with a digital mark on the side of each positioning protrusion; the center distance between two adjacent positioning protrusions of the short-distance positioning ruler is consistent with the center distance between two adjacent holes of the short-distance rubber chain, the center distance between two adjacent positioning protrusions of the medium-distance positioning ruler is consistent with the center distance between two adjacent holes of the medium-distance rubber chain, and the center distance between two adjacent positioning protrusions of the long-distance positioning ruler is consistent with the center distance between two adjacent holes of the long-distance rubber chain.
[0010] The outer diameter of each positioning protrusion of the short-distance positioning ruler is less than 2.8 mm, the outer diameter of each positioning protrusion of the medium-distance positioning ruler is less than 3.5 mm, and the outer diameter of each positioning protrusion of the long-distance positioning ruler is less than 4 mm.
[0011] Wherein, each of the rubber chain positioning rulers is a hard plastic part, and each of the positioning protrusions is injection-molded with the corresponding rubber chain positioning ruler to form an integral structure.
[0012] The upper end portion of each positioning boss is in a cone shape that is narrow at the top and wide at the bottom.
[0013] The lower surface of the short-distance positioning ruler is provided with a first air-avoiding arc groove for the positioning protrusion of the medium-distance positioning ruler to pass through, and the lower surface of the medium-distance positioning ruler is provided with a second air-avoiding arc groove for the positioning protrusion of the long-distance positioning ruler to pass through.
[0014] The length of the short-distance positioning ruler is smaller than the length of the middle-distance positioning ruler, and the length of the middle-distance positioning ruler is smaller than the length of the long-distance positioning ruler.
[0015] Compared with the prior art, the present invention has the following beneficial effects, specifically:
[0016] 1. The rear ends of the three rubber chain positioning rulers are pivoted by a pivot. When in use, the three rubber chain positioning rulers can rotate relative to each other. When not in use, the three rubber chain positioning rulers are folded together, which can effectively reduce the storage space and improve the convenience of storage.
[0017] 2. The utility model can assist in cutting orthodontic rubber chains of different hole spacings to a fixed length by using short-distance positioning rulers, medium-distance positioning rulers, and long-distance positioning rulers. During cutting, the cutting position of the orthodontic rubber chain roll can be accurately determined by matching the positioning bosses with the corresponding digital markings, thereby ensuring the accuracy and convenience of cutting orthodontic rubber chains to a fixed length.
[0018] 3. Therefore, the utility model has the advantages of novel structural design and easy use, and can effectively improve the efficiency and accuracy of cutting orthodontic rubber chains. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described below in conjunction with specific implementation methods.
[0028] Example 1, as Figures 1 to 5 As shown, an orthodontic rubber chain auxiliary cutting tool includes three rubber chain positioning rulers, each of which is in the shape of a long strip and arranged in sequence from top to bottom. The rear ends of the three rubber chains are pivotally connected by a pivot 4. The three rubber chain positioning rulers are, from top to bottom, a short-distance positioning ruler 1 suitable for short-distance rubber chains, a medium-distance positioning ruler 2 suitable for medium-distance rubber chains, and a long-distance positioning ruler 3 suitable for long-distance rubber chains.
[0029] Among them, Figures 1 to 5As shown, the upper surface of each rubber chain positioning ruler is respectively provided with a plurality of positioning protrusions 5 distributed in a linear array along the length direction of the corresponding rubber chain positioning ruler, and the upper surface of the rubber chain positioning ruler is respectively provided with a digital mark 6 next to each positioning protrusion 5; the center distance between two adjacent positioning protrusions 5 of the short-distance positioning ruler 1 is consistent with the center distance between two adjacent holes of the short-distance rubber chain, the center distance between two adjacent positioning protrusions 5 of the medium-distance positioning ruler 2 is consistent with the center distance between two adjacent holes of the medium-distance rubber chain, and the center distance between two adjacent positioning protrusions 5 of the long-distance positioning ruler 3 is consistent with the center distance between two adjacent holes of the long-distance rubber chain.
[0030] It needs to be explained that if Figure 1 、 Figure 3 as well as Figure 4 As shown, for each rubber chain positioning ruler, the content of the digital mark 6 next to the positioning boss 5 at the first position is 1, the content of the digital mark 6 next to the positioning boss 5 at the second position is 2, the content of the digital mark 6 next to the positioning boss 5 at the third position is 3, and so on. The content of the digital mark 6 is adapted to the position of the positioning boss 5.
[0031] In addition, the outer diameter of each positioning boss 5 of the short-distance positioning ruler 1 is less than 2.8 mm, the outer diameter of each positioning boss 5 of the medium-distance positioning ruler 2 is less than 3.5 mm, and the outer diameter of each positioning boss 5 of the long-distance positioning ruler 3 is less than 4 mm.
[0032] It should be noted that the rear ends of the three rubber chain positioning rulers of the present embodiment are pivotally connected by a pivot 4. When in use, the three rubber chain positioning rulers can rotate relative to each other. When in use, the required rubber chain positioning rulers are unscrewed to assist in cutting orthodontic rubber chains. When not in use, such as Figure 5 As shown, the three rubber chain positioning rulers are folded together, which can effectively reduce the storage space and improve the convenience of storage.
[0033] When using the short-distance positioning ruler 1 to assist in cutting the short-distance rubber chain, the medical staff pulls out the short-distance rubber chain roll and unfolds it, and aligns the hole at the head position with the corresponding positioning protrusion 5 according to the required cutting length. For example: when it is necessary to cut a short-distance rubber chain with a length of 6 holes, align the hole at the head position of the roll and insert it into the positioning protrusion 5 with the number mark 6 being 6; when it is necessary to cut a short-distance rubber chain with a length of 10 holes, align the hole at the head position of the roll and insert it into the positioning protrusion 5 with the number mark 6 being 10; after the hole at the head position of the roll is inserted into the position, stretch the roll from back to front along the short-distance positioning ruler 1 and unfold it so that the hole position of the roll is inserted into the positioning protrusion 5 at the corresponding position; when the roll is stretched and unfolded to the front side position of the short-distance positioning ruler 1, use scissors to cut the short-distance rubber chain roll at a certain position in front of the positioning protrusion 5 with the number mark 6 being 1 to obtain a short-distance rubber chain with the required hole position length and complete the short-distance rubber chain cutting.
[0034] Similarly, when using the middle distance positioning ruler 2 to assist in cutting the middle distance rubber chain, the middle distance positioning ruler 2 is unscrewed, the medical staff pulls out the middle distance rubber chain roll and unfolds it, and aligns the hole at the head position with the corresponding positioning protrusion 5 according to the required cutting length. For example: when it is necessary to cut a middle distance rubber chain with 4 holes, align the hole at the head position of the roll with the positioning protrusion 5 with the number mark 6 being 4; when it is necessary to cut a middle distance rubber chain with 12 holes, align the hole at the head position of the roll with the positioning protrusion 5 with the number mark 6 being 4. The hole of the coil is aligned and inserted into the positioning boss 5 with the number mark 6 being 12; after the hole at the head position of the coil is inserted into the position, the coil is stretched from back to front along the middle-distance positioning ruler 2 and the hole position of the coil is inserted into the positioning boss 5 at the corresponding position; when the coil is stretched and expanded to the front side of the middle-distance positioning ruler 2, use scissors to cut the middle-distance rubber chain coil at a certain position in front of the positioning boss 5 with the number mark 6 being 1, so as to obtain the middle-distance rubber chain with the required hole length and complete the middle-distance rubber chain cutting.
[0035] Similarly, when using the long-distance positioning ruler 3 to assist in cutting the long-distance rubber chain, the long-distance positioning ruler 3 is unscrewed, and the medical staff pulls out the long-distance rubber chain roll and unfolds it, and aligns the hole at the head position with the corresponding positioning protrusion 5 according to the required cutting length. For example: when it is necessary to cut a long-distance rubber chain with 6 hole positions, align the hole at the head position of the roll with the positioning protrusion 5 with the number 6 as 6; when it is necessary to cut a long-distance rubber chain with 8 hole positions, align the hole at the head position of the roll with the positioning protrusion 5 with the number 6 as 6; The hole of the coil is aligned and inserted into the positioning boss 5 with the number mark 6 being 8; after the hole at the head position of the coil is inserted into the position, the coil is stretched from back to front along the long-distance positioning ruler 3 and the hole position of the coil is inserted into the positioning boss 5 at the corresponding position; when the coil is stretched and expanded to the front side position of the long-distance positioning ruler 3, use scissors to cut the long-distance rubber chain coil at a certain position in front of the positioning boss 5 with the number mark 6 being 1, so as to obtain a long-distance rubber chain with the required hole length and complete the long-distance rubber chain cutting.
[0036] It should be emphasized that the orthodontic rubber chain auxiliary cutting tool of the first embodiment of the present invention can assist in the fixed-length cutting of orthodontic rubber chains with different hole spacings through the short-distance positioning ruler 1, the medium-distance positioning ruler 2, and the long-distance positioning ruler 3, and during cutting, the cutting position of the orthodontic rubber chain roll can be accurately determined by coordinating the positioning boss 5 with the corresponding digital mark 6 to ensure the accuracy and convenience of the fixed-length cutting of the orthodontic rubber chain.
[0037] In summary, it can be seen that through the above structural design, the orthodontic rubber chain auxiliary cutting tool of the first embodiment has the advantages of novel structural design and easy use, and can effectively improve the efficiency and accuracy of orthodontic rubber chain cutting.
[0038] Embodiment 2: The difference between this embodiment 2 and embodiment 1 is that each rubber chain positioning ruler is a hard plastic part, and each positioning boss 5 is injection-molded with the corresponding rubber chain positioning ruler into an integral structure.
[0039] Specifically, each rubber chain positioning ruler is respectively formed by injection molding of plastic material, and the positioning protrusion 5 of each rubber chain positioning ruler is respectively formed by injection molding synchronously with the corresponding rubber chain positioning ruler.
[0040] Example 3, as Figures 3 to 5 As shown, the difference between the third embodiment and the first embodiment is that the upper end of each positioning boss 5 is in a cone shape that is narrow at the top and wide at the bottom.
[0041] When the hole of the orthodontic rubber chain is inserted into the positioning boss 5 for positioning, the positioning boss 5 with a cone-shaped upper end has the advantage of quick and convenient positioning and can further improve the convenience of use.
[0042] Example 4, as Figures 2 to 5 As shown, the difference between the fourth embodiment and the first embodiment is that a first air-avoiding arcuate groove 7 is provided on the lower surface of the short-distance positioning ruler 1 for the positioning protrusion of the medium-distance positioning ruler 2 to pass through, and a second air-avoiding arcuate groove 8 is provided on the lower surface of the medium-distance positioning ruler 2 for the positioning protrusion of the long-distance positioning ruler 3 to pass through.
[0043] When the rubber chain positioning ruler is rotated out or closed, the first arc-shaped groove 7 is used to avoid the positioning protrusion 5 of the center distance positioning ruler 2, and the second arc-shaped groove 8 is used to avoid the positioning protrusion 5 of the long distance positioning ruler 3.
[0044] Example 5, as Figure 5 As shown, the difference between the fifth embodiment and the first embodiment is that the length of the short distance positioning ruler 1 is smaller than the length of the middle distance positioning ruler 2 , and the length of the middle distance positioning ruler 2 is smaller than the length of the long distance positioning ruler.
[0045] Since the short-distance positioning ruler 1, the medium-distance positioning ruler 2 and the long-distance positioning ruler 3 are of different lengths, when in use, medical staff can quickly and conveniently unscrew the required rubber chain positioning ruler according to the hole spacing of the orthodontic rubber chain to be cut, thereby further improving the convenience of use.
[0046] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
