Description

Technical Field

[0001] The present invention relates to the technical field of stomatology, and particularly to a mesial resistance measurer for teeth. Background Art

[0002] A mesial resistance measurer for teeth is a tool used to measure the tightness or resistance of the mesial contact of teeth, which is of great significance in stomatology. Especially during operations such as tooth restoration, orthodontic treatment, and extraction of impacted wisdom teeth, there are mainly three common methods for tooth adjacency examination: dental floss examination, feeler gauge examination, and mesial examination. The tightness of the mesial contact is qualitatively evaluated by the magnitude of the resistance when the measurer enters the adjacent area.

[0003] For example, in a Chinese patent with a publication date of April 25, 2023, a patent name of "Tooth Adjacency Measurer and Measuring Method", and a publication number of CN107028676B, it includes a measuring member, an indicating device, and a handle. The indicating device is installed on the handle. The indicating device is composed of a pointer and a scale. The measuring member is fixedly connected to the end of the pointer away from the scale. There is a hinge point between the pointer and the handle, and an elastic connection device is provided between the pointer and the handle. Another Chinese patent with a publication number of CN215739604U, a patent name of "A Split-Type Tooth Adjacency Measurer", and a publication date of February 8, 2022, includes a grip. A scale is fixedly connected to the front surface of the grip. An organic glass cover plate is fixedly connected to the front surface of the scale. A first runner, a second runner, and a traction belt are arranged between the scale and the organic glass cover plate. A first rotating shaft is fixedly connected to the inside of the first runner, and a hand wheel is fixedly connected to the top of the first rotating shaft. A second rotating shaft is fixedly connected to the inside of the second runner. A fixed shaft is slidably connected to the inside of the second rotating shaft. A measuring wheel is fixedly connected to the outer surface of the fixed shaft. A measuring scale is integrally formed on the side surface of the measuring wheel. A card slot is opened on the side wall of the fixed shaft. A limiting strip is integrally formed inside the second rotating shaft. By rotating the measuring scale in the tooth gap, the value of the tooth adjacency can be accurately obtained according to the corresponding value on the scale. By setting the card slot and the limiting strip, the fixed shaft cannot rotate self - sufficiently inside the second rotating shaft.

[0004] Among the above - mentioned existing technologies, there are the following technical problems: When the existing measurer measures the distance between the mesial surfaces of teeth, it inserts a measuring piece between the mesial surfaces of teeth for measurement.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figures 1-9, when the existing measuring device measures the distance between adjacent tooth surfaces, it inserts a measuring piece between the adjacent tooth surfaces for measurement. However, in actual operation, the detection head of the measuring device cannot be adjusted in angle, so it is easy to increase the overall measurement difficulty due to the non-corresponding angle of the detection head during the operation. To solve this technical problem, the following technical content is disclosed in this embodiment. The adjacent tooth surface resistance measuring device includes a hand-held frame 1 and a grip 2 fixed to the end of the hand-held frame 1. A main measuring plate 3 is installed inside the hand-held frame 1, and a guiding shaft 4 is installed above the front end of the main measuring plate 3. A measuring piece 7 is installed at the front end of the main measuring plate 3 through a central rod 8, and a scroll spring 9 that provides a reset elastic force is installed outside the central rod 8. The guiding shaft 4 at the upper end of the main measuring plate 3 is installed on an angle adjustment component 5, and a limiting component 6 is arranged above the angle adjustment component 5. The limiting component 6 is used for fixing the main measuring plate 3 after angle adjustment. The main measuring plate 3 forms a rotational connection structure with the hand-held frame 1 through the guiding shaft 4, and the measuring piece 7 can rotate at the end of the main measuring plate 3 through the central rod 8. The angle adjustment component 5 includes a driving wheel 501, a transmission belt 502, and a lever 503. The two driving wheels 501 are connected to each other through the transmission belt 502, and one of the driving wheels 501 is fixed on the guiding shaft 4, and a lever 503 is fixed to the side of the other driving wheel 501. The limiting component 6 includes a support frame 601, a limiting pressure plate 602, and an auxiliary spring 603. The support frame 601 is fixed to the upper end of the hand-held frame 1. The limiting pressure plate 602 is installed through the support frame 601, and an auxiliary spring 603 is arranged outside the middle rod of the limiting pressure plate 602. The auxiliary spring 603 is located between the lower end of the limiting pressure plate 602 and the support frame 601. The limiting pressure plate 602 is located above the driving wheel 501 fixed with the lever 503, and the middle rod of the limiting pressure plate 602 is slidably connected to the support frame 601. The longitudinal section of the measuring piece 7 is set as a semi-circular structure, and the thickness of the middle part of the measuring piece 7 gradually increases towards the outside. The central rod 8 is connected to a moving substrate 11 through a traction rope 10, and a pointer 12 is fixed to the upper end of the moving substrate 11. A scale line 13 is arranged on the side of the pointer 12, and the scale line 13 is opened on the main measuring plate 3. A power pull ring 14 is fixed to the moving substrate 11, and a sliding block 15 fixed to the back of the moving substrate 11 is arranged in a guiding groove 16 on the main measuring plate 3. The sliding block 15 is connected to the guiding groove 16 through a built-in spring 17. The outer wall of the sliding block 15 on the back of the moving substrate 11 is attached to the inner wall of the guiding groove 16, and the sliding block 15 on the back of the moving substrate 11 can slide on the guiding groove 16.

[0040] When the tooth proximal surface measurer needs to be used, push the limit pressing disc 602 upward with a finger to separate the lower end of the limit pressing disc 602 from the lower transmission wheel 501. At this time, push the lever 503. After the lever 503 moves, it can make the transmission wheel 501 rotate. When the transmission wheel 501 rotates, it can make another transmission wheel 501 rotate by using the transmission belt 502. When the transmission wheel 501 rotates, the main measuring plate 3 can be adjusted in angle through the guide shaft 4. After the angle of the main measuring plate 3 is adjusted, release the limit pressing disc 602. The limit pressing disc 602 rebounds under the action of the auxiliary spring 603. After resetting, the limit pressing disc 602 presses on the transmission wheel 501 to limit the transmission wheel 501, preventing the transmission wheel 501 from rotating automatically after the angle adjustment is completed. At the same time, multiple anti-slip lines are evenly distributed on the lower surface of the limit pressing disc 602. The setting of the anti-slip lines can increase the contact friction between the limit pressing disc 602 and the transmission wheel 501 and improve the stability when limiting the transmission wheel 501. After the angle adjustment is completed, place the thinnest position of the measuring piece 7 at the front end of the main measuring plate 3 between adjacent teeth. Then, hold the power pull ring 14 with your hand. After the power pull ring 14 moves, it can drive the moving substrate 11 to move synchronously. The movement of the moving substrate 11 can drive the central rod 8 to rotate through the traction rope 10. When the central rod 8 rotates, it can make the measuring piece 7 rotate synchronously. At this time, the edge of the rotating measuring piece 7 rotates between the teeth from thin to thick until the measuring piece 7 cannot rotate between adjacent teeth. When the measuring piece 7 cannot rotate, the pointer 12 on the moving substrate 11 points to the scale line 13 on the main measuring plate 3, so as to measure the tooth gap between adjacent teeth. A sliding block 15 is installed on the back of the moving substrate 11. By moving the sliding block 15 in the guiding groove 16 opened on the main measuring plate 3, the stability of the moving substrate 11 during movement can be improved. After the measurement is completed, release the power pull ring 14. The moving substrate 11 rebounds under the action of the built-in spring 17, and the central rod 8 and the measuring piece 7 also reverse under the action of the scroll spring 9.

[0041] Human tooth shapes vary. Even in the oral cavity of the same person, the proximal surface shapes of different teeth may also be different. Through the setting of the angle adjustment component 5, the angle of the measuring piece 7 at the front end of the main measuring plate 3 can be adjusted, enabling the measurer to adapt to the proximal surface shapes of different teeth and meet various measurement requirements. Whether it is anterior teeth, posterior teeth or wisdom teeth, the measurer can ensure the best contact between the measuring piece 7 and the tooth proximal surface through angle adjustment, thereby improving the applicability and flexibility of the measurement.

[0042] Example Two: The technical content disclosed in this example is a further improvement based on Example One above. The following technical content is disclosed in this example. A locking nut 18 is installed on the central rod 8 in the middle of the measuring piece 7. A protective cover 19 is arranged above the measuring piece 7, and the protective cover 19 is fixed at the end of the main measuring plate 3. The central rod 8 and the locking nut 18 are in threaded connection, and multiple anti-slip lines are arranged on the surface of the side of the locking nut 18 facing the end of the main measuring plate 3. The inside of the protective cover 19 is a hollow structure.

[0043] When measurement is not required, rotate the measuring piece 7 at the end of the main measuring plate 3 so that the measuring piece 7 rotates into the inside of the protective cover 19. Since the locking nut 18 on the central rod 8 in the middle of the measuring piece 7 does not fit with the main measuring plate 3 in the initial state, at this time, the measuring piece 7 can drive the locking nut 18 to rotate synchronously by the central rod 8 after rotation. After the measuring piece 7 finishes rotating, rotate the locking nut 18 on the central rod 8. After the locking nut 18 rotates, it can move on the central rod 8 and contact and press against the main measuring plate 3, thereby fixing the position of the rotated and adjusted measuring piece 7 and storing the measuring piece 7 into the inside of the protective cover 19, so as to provide a certain anti-pollution protection for the measuring piece 7 when the measuring piece 7 is not needed.
