A tooth proximal polishing device is usually equipped with a rotating or vibrating polishing head.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0045] The present invention provides Figure 1 , Figure 2 and Figure 5 As shown, a tooth proximal surface polishing device is used for grinding and polishing the patient's teeth in dental clinics, especially for grinding and polishing the tooth proximal surfaces; the main structure of the present invention includes: a device housing 1, a vibration head 2 and a driving assembly 3, the device housing 1 is provided with a hand grip, the hand grip is used for medical staff to hold; the vibration head 2 is arranged at one end of the device housing 1, and the end of the vibration head 2 away from the device housing 1 is provided with a bow 21, and the bow 21 is detachably connected with a dental polishing strip 4, and the two ends of the bow 21 are provided with a clamping part 211, and the two clamping parts 211 are respectively used to clamp the two ends of the dental polishing strip 4; the driving assembly 3 is arranged in the device housing 1, and the driving assembly 3 is used to make the vibration head 2 vibrate, wherein the vibration of the vibration head 2 will inevitably drive the bow 21 to vibrate, and then make the dental polishing strip 4 vibrate. In some embodiments, the vibration direction of the dental polishing strip 4 can be vibration along its own length or width direction.

[0046] The tiny rough parts, plaque and pigmentation on the tooth surface are removed by mechanical friction. For example, when using a polishing head containing fine diamond particles, the particles rub against the uneven parts of the tooth surface, gradually making the tooth surface smooth. This friction effect is similar to sandpaper polishing the surface of an object, but the material and design of the polishing head are specially optimized for the hardness and sensitivity of teeth to avoid damaging them.

[0047] Among them, an adjustment component 5 is provided on the vibration head 2, and the adjustment component 5 is used to adjust the tension at both ends of the bow 21. In some embodiments, the inner wall of the bow 21 can be supported by the adjustment component 5, so that the arc angle of the bow 21 is changed, so that the tension at both ends of the bow 21 changes. It should be noted that when the inner arc angle size of the bow 21 is forcibly expanded by the adjustment component 5, the tension at both ends of the bow 21 will increase accordingly. In this embodiment, the inner arc angle size of the bow 21 is changed by the adjustment component 5, so as to achieve the technical effect of adjusting the tension at both ends of the bow 21.

[0048] It should be noted that, in order to better polish the adjacent surfaces of the patient's teeth, an arched polishing head is usually used to support the polishing strip to polish the adjacent surfaces of the patient's teeth in dental clinics today. However, the unfolded size of the current arched polishing head is usually fixed. Therefore, in clinics, it is usually necessary to replace the arched polishing heads of different sizes for patients of different age groups to better fit the size of the patient's teeth. This structural design will lead to low clinical operation efficiency, and it is not possible to flexibly adjust the tension of the polishing strip, which affects the polishing efficiency of the patient's teeth.

[0049] In this solution, the tension at both ends of the bow 21 can be adjusted by adjusting the component 5, thereby achieving the technical effect of adjusting the tension at both ends of the dental polishing strip 4. At the same time, medical staff can adjust the size of the bow 21 according to the size of the patient's dentition, thereby better polishing the adjacent surfaces of the patient's teeth. Figure 2 , Figure 3 and Figure 4 As shown, the adjustment component 5 includes: an abutment plate 51, a lever 52 and an adjustment knob 53, the abutment plate 51 abuts against the inner wall of the bow portion 21, and the abutment plate 51 is used to adjust the distance between the two ends of the bow portion 21; one end of the lever 52 is connected to the abutment plate 51, a receiving groove 22 is provided on the vibration head 2, the lever 52 is received in the receiving groove 22, the receiving groove 22 and the lever 52 both extend along the extension direction of the vibration head 2, a tilting platform 521 is provided on the side wall of the lever 52, and the tilting platform 521 protrudes from the outer wall of the vibration head 2; the adjustment knob 53 is screwed on the side wall of the vibration head 2, and an inclined ring 531 is provided on the end of the adjustment knob 53 facing the tilting platform 521, the tilting ring 531 and the tilting platform 521 are both tilted toward the same side, and the tilting ring 531 is used to abut against the tilting platform 521.

[0050] It is understandable that if Figure 2 , Figure 3 and Figure 4As shown, when the medical staff needs to expand the size of the bow 21 or increase the tension of the dental polishing strip 4, they only need to turn the adjusting knob 53 to move it along the extension direction of the lever 52. The tilting ring 531 on the adjusting knob 53 abuts against the tilting platform 521 on the lever 52, thereby causing the lever 52 to swing upward; the distance between the abutting plate 51 and the inner side wall of the bow 21 is reduced through the lever 52, and the abutting plate 51 abuts against the inner side wall of the bow 21; the bow 21 is expanded through the abutting plate 51, so that the tension between the two ends of the bow 21 is increased.

[0051] On the contrary, when the medical staff needs to reduce the size of the bow 21 or reduce the tension of the dental polishing strip 4, they only need to rotate the adjusting knob 53 in the opposite direction to move it along the other direction of the lever 52. The tilting ring 531 on the adjusting knob 53 is moved away from the tilting platform 521 on the lever 52, so that the lever 52 swings downward; the distance between the abutting plate 51 and the inner side wall of the bow 21 is increased through the lever 52, so that the bow 21 can reduce the expanded size through its own restoring force, and the tension between the two ends of the bow 21 is reduced.

[0052] In some embodiments, the abutment plate 51 and the lever 52 are integrally formed to increase the overall structural strength of the abutment plate 51 and the lever 52 , so that the adjustment assembly 5 can better adjust the bow portion 21 .

[0053] Furthermore, the abutting plate 51 is an arc-shaped elastic plate, the bending angle of the arc-shaped elastic plate is smaller than the bending angle of the bow portion 21, and both ends of the arc-shaped elastic plate abut against the inner side wall of the bow portion 21. The arc-shaped elastic plate has sufficient elasticity so that it can have sufficient restoring force.

[0054] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, a movable ball head 522 is provided at one end of the lever 52 away from the abutment plate 51, and the lever 52 is movably connected to the receiving groove 22 through the movable ball head 522. The movable ball head 522 allows the lever 52 to have a certain swing range and prevents it from easily falling out of the receiving groove 22.

[0055] Furthermore, the bow portion 21 is an elastic bow portion 21. The elastic bow portion 21 has sufficient elasticity so that it can have sufficient restoring force.

[0056] Further, such as Figure 6As shown, a polishing layer 04 is provided on one side of the dental polishing strip 4. The polishing layer 04 is used to polish the adjacent surfaces of the patient's teeth. A plurality of polishing segments 41 are provided on the polishing layer 04. The friction coefficients of two adjacent polishing segments 41 are different. Specifically, the plurality of polishing segments 41 are arranged along the extension direction of the polishing layer 04, and the plurality of polishing segments 41 transition from coarse sand to fine sand step by step. In some embodiments, five polishing segments 41 are provided on the polishing layer 04, and the length of each polishing segment 41 is 1 cm. In other embodiments, a silicone rubber polishing segment is also provided at the end of the polishing layer 04.

[0057] Furthermore, when using this device, it can be used in conjunction with a manual roller. The polishing bar can be manually moved back and forth by the manual roller to ensure that there is always granular frosting in the polishing area. If sand falls off during the friction process, the manual roller can be manually rolled away by about 5mm; if the friction process of the current particle size meets the standard, you can press the button, the polishing bar will move away 1cm, and enter the next particle size for polishing until the entire process polishing procedure is completed, reaching a very ideal adjacent surface polishing level.

[0058] Further, such as Figure 5 As shown, a mounting frame 11 is disposed in the device housing 1 , and the driving assembly 3 is disposed on the mounting frame 11 . The mounting frame 11 is used to fix the driving assembly 3 .

[0059] It is understandable that installing the drive assembly 3 on the mounting frame 11 can make the drive assembly 3 more integrated, so that the overall weight of the drive assembly 3 is concentrated together, so as to better suppress the reaction force when the vibration head 2 vibrates, and further the vibration energy of the vibration head 2 is better transmitted to the bow 21.

[0060] Further, such as Figure 5 As shown, a plurality of buffers 111 are provided on the mounting frame 11, and the mounting frame 11 is connected to the inner wall of the device housing 1 through the buffers 111. The mounting frame 11 is isolated from the inner wall of the device housing 1 through the buffers 111. In this way, the vibration energy of the driving component 3 when working can be isolated within a certain range. It is prevented that excessive vibration is transmitted to the palm of the medical staff when the polishing device is working. The user experience of the polishing device is improved.

[0061] Further, such as Figure 5As shown, the driving assembly 3 includes: a vibration generating element 31, a circuit board 32, a battery 33 and at least one button 34. The vibration generating element 31 is arranged on one end of the mounting frame 11 close to the vibration head 2, and the output shaft of the vibration generating element 31 is connected to the vibration head 2; the circuit board 32 is arranged on the mounting frame 11; the battery 33 is arranged on the mounting frame 11; the button 34 passes through the outer wall of the device housing 1, and at least one button 34 is used to start or shut down the vibration generating element 31. In some other embodiments, a speed regulating button is also arranged on the device housing 1, and the working frequency of the vibration generating element 31 is adjusted by the speed regulating button.

[0062] The vibration generating element 31 , the battery 33 and the button 34 are all electrically connected to the circuit board 32 .

[0063] It is understandable that the battery 33 can provide electrical energy to the circuit board 32 and the vibration generating element 31 .

[0064] Furthermore, at least one of the vibration generating element 31 and the vibration head 2 is provided with a pressure sensor. The pressure sensor is used to detect the magnitude of the friction force of the device when it is working. Specifically, the pulling force when the handheld polishing device is initially placed is set as the initial force value, and when the polishing action is started, the force increased by the friction force is set as the working force value. If the difference between the two force values ​​increases significantly, it means that the adjacent surfaces of the teeth are obviously rough, and the machine will continue to work without power failure; on the contrary, if the difference between the two force values ​​is very small, it means that the adjacent surfaces are close to being smooth, and the machine will automatically power off and stop with a buzzer prompt, and you can manually enter the next granularity friction strip stage.

[0065] A second aspect of the present application provides a polishing strip tension adjustment method for a tooth proximal surface polishing device according to any one of the first aspects, the polishing strip tension adjustment method comprising the following steps:

[0066] Step 1: Turn the adjusting knob 53 to displace the adjusting knob 53 along the length direction of the lever 52;

[0067] Step 2: Make the tilting ring 531 on the adjusting knob 53 approach or move away from the tilting platform 521 on the lever 52, so as to make the lever 52 swing upward or downward;

[0068] Step 3: The distance between the abutting plate 51 and the inner side wall of the bow portion 21 is changed by using the lever 52. The abutting plate 51 is disposed at one end of the lever 52, and the abutting plate 51 abuts against the inner side wall of the bow portion 21;

[0069] Step 4: The bow portion 21 is then expanded or contracted, so that the tension between the two ends of the bow portion 21 increases or decreases.

[0070] In summary, the present application provides a proximal surface polishing device and a method for adjusting the tension of a polishing strip. The present solution can adjust the tension at both ends of the arch 21 by adjusting the component 5, thereby achieving the technical effect of adjusting the tension at both ends of the dental polishing strip 4. At the same time, medical staff can adjust the size of the arch 21 according to the size of the patient's dentition, thereby better polishing the proximal surfaces of the patient's teeth.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
