Description

Technical Field

[0001] The present invention relates to the field of oral medicine teaching, and in particular to a training device for oral medicine teaching and a use method thereof. Background Art

[0002] As a key branch of medicine, dentistry focuses on the research, diagnosis, treatment and prevention of various diseases in the oral and maxillofacial areas. Before becoming a qualified dentist, medical students must undergo rigorous theoretical learning and extensive clinical practice training. Traditionally, this practice often requires students to operate directly on real patients, which not only increases the potential risks for patients, but may also lead to misoperation due to students' lack of skills.

[0003] With the advancement of technology, modern dental education has introduced simulation training devices to reduce these risks. These devices provide students with a risk-free learning environment, allowing them to practice repeatedly until they are skilled, thus avoiding potential harm to actual patients. However, many existing training models have some limitations that affect their effectiveness and practicality in teaching:

[0004] 1. Teeth are not replaceable: The teeth of most existing models are fixed and cannot reflect situations where teeth fall out or have different shapes, nor can they replace worn tooth parts, resulting in limited usage scenarios and high maintenance costs.

[0005] 2. Insufficient adjustment of mouth opening: The model usually simulates the opening and closing of the upper and lower jaws through simple mechanical connections, lacking the function of accurately controlling and fixing a specific mouth opening, which poses an obstacle to certain operations that require fine adjustment.

[0006] 3. The occlusal relationship cannot be adjusted: Due to the lack of the ability to adjust the position of the upper and lower teeth, the model is difficult to accurately reproduce complex conditions such as caries and malocclusion, which limits students' learning effects when facing such cases.

[0007] Although some advanced simulation tools that combine electric motors with computer programs have appeared on the market and partially solve the above problems, their high cost, large size and complex maintenance requirements make it difficult to popularize them in a wider teaching environment.

[0008] Therefore, it is necessary to develop a new type of oral medicine training device, which should have the following characteristics:

[0009] 1. Replaceable tooth components to simulate various tooth conditions and facilitate maintenance.

[0010] 2. Accurate and fixable mouth opening adjustment mechanism to enhance the authenticity of simulation.

[0011] 3. The ability to move the upper and lower jaws can simulate a variety of occlusal abnormalities.

[0012] At the same time, such a device must be reasonably priced and compact so that it can be widely used in schools and other training venues.

[0013] In summary, designing such an economical and efficient oral medical training device is of great significance to improving the quality of oral medical education, and will help cultivate more professional and confident oral medical talents.

[0031] A method for using a training device for oral medicine teaching comprises the following steps:

[0032] S1. Confirm teaching tasks and teaching needs;

[0033] S2. Select and operate different structures and make adjustments according to teaching tasks and teaching needs.

[0034] Further, Ss1, when the mouth opening needs to be adjusted, the user needs to rotate the screw part 2 to drive the screw rod 2 to rotate, and at this time, the threaded block 2 changes its position on the screw rod 2. Since the position of the fixed block 3 remains unchanged, the length of the rotating rod remains unchanged, and thus the angle between the rotating rod and the screw rod 2 will change, thereby causing the angle between the upper and lower gums and the tooth chamber to change, and finally changing the mouth opening of the device;

At this time, the telescopic gas column is adjusted by force, thereby changing the positions of the upper and lower gums and the dental model;

[0036] Ss3. When the rotation of the upper and lower gums needs to be adjusted, the user needs to hold the gums or the tooth chamber at the target end and apply pressure to rotate it. At this time, the tooth chamber changes its relative position with the sliding seat, so that the slider slides in the arc groove, and at the same time, the rotating block rotates in the sliding groove, so as to achieve the misalignment of the upper and lower gums and the dental model;

[0037] Ss4. When it is necessary to disassemble any dental model, the user needs to use an additional screwdriver, loosen the screws, and screw them together with the threaded fixing holes on the dental model to remove the dental model together with the threaded fixing holes.

[0038] Compared with the prior art, the present invention has the following advantages including but not limited to:

[0039] 1. Modular tooth replacement function: The device designed by the present invention supports the independent replacement of a single tooth. According to actual teaching needs, tooth models with different degrees of wear or abnormal morphology can be flexibly replaced to simulate various clinical tooth conditions. This feature not only reduces maintenance costs, but also enhances the application scope of the device, making it adaptable to a wider range of teaching scenarios.

[0040] 2. Precise and controllable mouth opening adjustment: The device designed by the present invention enables users to finely adjust the opening and closing angles of the upper and lower jaws through the integrated mouth opening adjustment component. This adjustment mechanism ensures that the opening position after setting is stable and unchanged, avoiding unexpected changes during operation, thereby providing a stable and interference-free learning environment for specific training in medical education.

[0041] 3. Multi-dimensional adjustability promotes realistic simulation: The device designed by the present invention is equipped with longitudinal and telescopic rotation adjustment components, which allow the upper and lower gums, teeth and even the inner wall of the oral cavity to be displaced and rotated in three dimensions. This high degree of freedom design makes it possible to simulate complex oral diseases such as jaw dislocation and malocclusion, which greatly promotes students' understanding of such diseases and the development of practical skills.

[0054] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0055] Please refer to the instruction manual Figures 1 to 11 The present invention discloses a training device for oral medicine teaching, which mainly includes an overall device and a supporting component. The supporting component consists of a vertical rod 9 and a base 10 arranged below the vertical rod 9. The vertical rod 9 is provided with a bend at an upper part thereof. At the bend, the vertical rod 9 is fixedly connected by a fixed block 11. The fixed block 11 is concave in shape, with an opening facing forward, and a plug-in shaft 12 is plugged thereon. Under normal conditions, the plug-in shaft 12 can rotate relative to the fixed block 11. When in use, the relative position of the plug-in shaft 12 and the fixed block 11 can be locked by an additional nut and screw to stop the rotation, thereby laying a foundation for adjusting the pitch angle of the above-mentioned overall device.

[0056] Next is the device as a whole, which mainly includes gums 1, dental molds 2, tooth chambers 3, face masks 4 and jaw masks 5, and also includes longitudinal adjustment components, telescopic rotation adjustment components and mouth opening adjustment components for connecting them, wherein the gums 1 are arranged to be symmetrical and corresponding to each other, and their shapes simulate the shape of the gums inside the human mouth, and the gums 1 are also provided with a plurality of through mounting holes 6, and screws 7 are arranged in the mounting holes 6 for fixing the dental molds 2. Specifically, threaded fixing holes 8 are fixedly connected to the dental molds 2 for use with the screws 7. In actual applications, the dental molds 2 are provided with threaded fixing holes 8. The fixing hole 8 is inserted into the gum 1 from the bottom of the mounting hole 6, and the threaded mouth of the threaded fixing hole 8 is aligned with the screw 7. Then, a screwdriver is used to install it, or it can be disassembled as needed. The advantage of such a design is that each dental mold 2 can be replaced individually. When any dental mold 2 is damaged, or it needs to be replaced with a dental mold 2 of another shape according to teaching needs, it can be quickly disassembled and assembled without replacing the entire device, and the dental mold 2 should be set to different sizes, specifications, damage degrees, etc., so as to facilitate the demonstration and teaching of different symptoms after installation.

[0057] Next is the telescopic rotation adjustment component, which consists of two parts, one of which is arranged behind the tooth chamber 3. For details, please refer to the attached manual. Figure 7 A circular arc-shaped slide groove 22 is provided at the rear of the tooth chamber 3, and a rotating block 21 adapted to its shape is arranged inside the slide groove 22. The rotating block 21 can rotate and slide inside the slide groove 22. Of course, in order to prevent it and the subsequent components from being stuck by the edge of the slide groove 22 during the rotation process, the rear part of the rotating block 21 should partially protrude from the slide groove 22. When the rotating block 21 rotates, the protruding part rotates to abut against the edge of the slide groove 22, and then rotates to the maximum, and the same is true in the reverse direction. At the same time, the rotation amplitude up and down can also be adjusted. A telescopic gas column 23 is fixedly connected to the rear of the rotating block 21. The telescopic gas column 23 includes an outer column and an inner column. The outer column and the inner column have a certain damping force when they are telescoped and changed in relative position by gas damping or friction damping. This part of the damping force enables the telescopic gas column 23 to have a certain force to maintain the status quo when it is not telescoped. Since the above-mentioned gas damping, friction damping, etc. are all common technologies in the prior art, their technical principles are not repeated here.

[0058] Another part of the telescopic rotation adjustment component is arranged below the tooth chamber 3. For details, please refer to the attached manual. Figure 6A circular arc-shaped arc groove 25 is provided under the tooth chamber 3, and a slider 24 is slidably connected inside the arc groove 25. The slider 24 is made of metal material, and a layer of silicone layer is pressed on the groove surface of the arc groove 25. The silicone layer is in contact with the metal material, which increases the damping, so that the user needs to apply a certain force when adjusting the rotation. This part of the force is also converted into a stabilizing force after the adjustment is completed, so that the angle and orientation of the tooth chamber 3 after adjustment cannot be changed at will.

[0059] Then there is the longitudinal adjustment assembly, as shown in the instruction manual. Figures 5-6 As shown, it includes a sliding seat 13 fixed on a slider 24, a threaded block 14 is fixedly connected to the side of the sliding seat 13 away from the slider 24, and a screw rod 15 is connected to the internal thread of the sliding seat 13, and a screw part 16 is fixedly connected to the front end of the screw rod 15 for screwing the screw rod 15, and the screw rod 15 is supported by a moving seat 18, and the screw rod 15 is rotatably connected to the moving seat 18. As the user screws the screw part 16, under the influence of the threaded connection, the threaded block 14 changes its relative position to the screw rod 15, thereby achieving a change in the position of the tooth chamber 3 connected thereto, and at this time, the telescopic air column 23 mentioned above will also perform synchronous telescopic changes, so that the upper and lower tooth chambers 3, and the gums 1 and dental models 2 connected thereto can change their positions according to actual teaching needs, and are used to simulate the symptoms of oral diseases such as malocclusion and malocclusion, and are convenient for showing to medical students. In order to prevent it from being unstable during the movement, the present invention is also provided with a sliding block 17 on the threaded block 14, and as shown in the attached Fig.10 As shown, a cavity 19 is provided inside the movable seat 18 , and a guide rod 20 is fixedly connected inside the cavity 19 . The guide rod 20 is inserted into and slides on the sliding block 17 to provide a stabilizing force for the sliding block 17 during movement.

[0060] Finally, there is the mouth opening adjustment component. Please refer to the instructions for Figures 8-9 , Fig.11Specifically, the assembly includes a rotating part 27 fixedly connected to the plug shaft 12, and the upper and lower parts of the front end of the rotating part 27 are plugged with the plug shaft 5 39, and the plug shaft 5 39 is rotatably connected to the rotating plate 28. The plug shaft 2 36 is plugged into the rear of the telescopic gas column 23, and the plug shaft 2 36 is rotatably connected to the rotating plate 28; this connects the tooth chamber 3 and the structure thereon and the mouth opening adjustment assembly together, and then, an extension part 29 is provided at the front end of the rotating part 27, and the front end bearing of the extension part 29 is connected to the screw rod 2 31 with the screw part 2 30, and the screw rod 2 31 is threadedly connected with the thread block 2 32, and the top and bottom ends of the thread block 2 32 are fixedly connected with the fixed block 2 33, and the fixed block 2 33 is plugged with the plug shaft 4 38, and the plug shaft 4 38 is rotatably connected to the rotating rod 34, and the plug shaft 3 37 is plugged on the other side of the rotating rod 34, through The rotating rod 34 is connected to the fixed block 35 arranged at the bottom of the movable seat 18 through the insertion shaft 37. This design allows when the user turns the screwing part 2 30, the screw rod 2 31 rotates under the action of the threaded connection, changing its positional relationship with the threaded block 2 32. Through the above adjustment, the opening degree is changed. The adjustment size of the opening degree is related to the thread pitch of the screw rod 2 31, so it can be adjusted more finely. When the screwing part 2 30 stops being turned, it is still affected by the thread. The opening degree can stop at this position and will not be changed due to collision or other reasons, making it more stable.

[0061] In order to simulate the structure of the human face more realistically and make medical students feel more involved in the practice, the present invention also fixes a buckle portion 26 adapted to the curved surface on the curved outer surface of the gum 1, and is used to buckle the face mask 4 and the jaw mask 5 respectively. Buckle edges are provided on the adjacent end surfaces of the face mask 4 and the jaw mask 5, and the buckle edges can be connected to the buckle portion 26 in a buckle-like manner to facilitate disassembly and assembly.

[0062] Based on the above embodiments, the present invention also proposes a method for using the training device for oral medicine teaching according to the above design. The method includes how to operate the above device, which mainly consists of the following two parts:

[0063] S1. Confirm teaching tasks and teaching needs;

[0064] S2. Select and operate different structures and make adjustments according to teaching tasks and teaching needs.

[0065] Specifically, when the mouth opening needs to be adjusted, the user needs to screw the second screwing part 30 to drive the second screw 31 to rotate. At this time, the second threaded block 32 changes its position on the second screw 31. Since the position of the fixed block 35 remains unchanged, the length of the rotating rod 34 remains unchanged, and the angle between the rotating rod 34 and the second screw 31 will change, thereby causing the angle between the upper and lower gums 1 and the tooth chamber 3 to change, and finally changing the mouth opening of the device. In this process, the rotating plate 28 makes some adaptive rotation adjustments around the plug shaft 5 39 to assist the tooth chamber 3 to rotate;

[0066] Ss2. When it is necessary to adjust the front and back arrangement of the upper and lower gums 1, the user needs to screw the screw part 16 and drive the screw rod 15 to rotate. At this time, the threaded block 14 changes its position on the screw rod 15, thereby driving the sliding seat 13, the tooth chamber 3 and the gums 1 to change their positions. At this time, the telescopic gas column 23 is adjusted by force to expand and contract, thereby changing the positions of the upper and lower gums 1 and the dental mold 2;

[0067] Ss3, when it is necessary to adjust the rotation of the upper and lower gums 1, it is necessary to hold the target end gums 1 or the tooth chamber 3 and apply pressure to rotate it. At this time, the tooth chamber 3 changes its relative position with the sliding seat 13, so that the slider 24 slides in the arc groove 25, and at the same time, the rotating block 21 rotates in the sliding groove 22, so as to achieve the misalignment of the upper and lower gums 1 and the dental mold 2;

[0068] Ss4. When any dental model 2 needs to be disassembled, the user needs to use an additional screwdriver to loosen the screw 7, and screw it into the threaded fixing hole 8 on the dental model 2 to remove the dental model 2 together with the threaded fixing hole 8.

[0069] Finally, in summary, the oral medicine teaching training device designed by the present invention can solve the problems in the prior art such as the inability to replace teeth arbitrarily, the inconvenient adjustment of the mouth opening degree, and the inability to adjust the misalignment of teeth. At the same time, the device designed by the present invention has a simple structure, does not rely on computers and other systems, and is easy to apply to the sinking market.

[0070] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.

The training device for oral medicine teaching according to claim 5, characterized in that: The front end of the gum (1) is fixedly connected with a buckle portion (26), and the adjacent end surfaces of the face mask (4) and the jaw mask (5) are provided with buckle edges, which can be connected to the buckle portion (26) in a buckle-type manner.

9. The method for using the training device for oral medicine teaching according to any one of claims 1 to 8, characterized in that: The steps include: S1. Confirm teaching tasks and teaching needs; S2. Select and operate different structures and make adjustments according to teaching tasks and teaching needs.

10. The method according to claim 9, characterized in that: Ss1. When the mouth opening degree needs to be adjusted, the user needs to rotate the second screwing part (30) to drive the second screw rod (31) to rotate. At this time, the second threaded block (32) changes its position on the second screw rod (31). Since the position of the third fixed block (35) remains unchanged, the length of the rotating rod (34) remains unchanged, and thus the angle between the rotating rod (34) and the second screw rod (31) will change, thereby causing the angle between the upper and lower gums (1) and the tooth chamber (3) to change, and finally changing the mouth opening degree of the device; Ss2. When it is necessary to adjust the front and back arrangements of the upper and lower gums (1), the user needs to rotate the screw part (16) to drive the screw rod (15) to rotate. At this time, the threaded block (14) changes its position on the screw rod (15), thereby driving the sliding seat (13), the tooth chamber (3) and the gums (1) to change their positions. At this time, the telescopic air column (23) is adjusted to be telescopic under force, thereby changing the positions of the upper and lower gums (1) and the dental model (2); Ss3. When the rotation of the upper and lower gums (1) needs to be adjusted, the user needs to hold the gums (1) or the tooth cavity (3) at the target end and apply pressure to rotate it. At this time, the tooth cavity (3) changes the relative position between it and the sliding seat (13), so that the slider (24) slides in the arc groove (25) and at the same time, the rotating block (21) rotates in the sliding groove (22), so as to achieve the misalignment of the upper and lower gums (1) and the tooth model (2); Ss4. When any dental model (2) needs to be disassembled, the user needs to use an additional screwdriver to loosen the screw (7) and screw it into the threaded fixing hole (8) on the dental model (2), so that the dental model (2) and the threaded fixing hole (8) can be disassembled.
