Description

Technical Field

[0001] This application relates to the technical field of oral cavity models, and in particular to a simulated oral cavity model. Background Technology

[0002] Oral models are models used to demonstrate the structure of the human oral cavity in teaching, and they are divided into various types according to different teaching purposes.

[0003] According to the new edition of the "Standards for Oral Medicine Education," students need to be able to dynamically understand the process of alveolar bone disease, but a single model can only demonstrate 2-3 fixed pathological morphologies. Furthermore, common oral models are all one-piece designs, which can only demonstrate a relatively limited distribution and pathological state of teeth, thus restricting teaching demonstrations. Utility Model Content

[0004] The purpose of this utility model application is to improve the problem that existing teaching oral models can only display a single pathological state. This application provides a simulated oral model.

[0005] The simulated oral cavity model provided in this application adopts the following technical solution:

[0006] A simulated oral cavity model, including

[0007] The model base has the incisor area corresponding to the middle part of the jawbone and the molar area corresponding to the two sides of the jawbone. The incisor area is equipped with an intermediate body, and the incisors and canines are installed on the intermediate body.

[0008] The stabilizing strip is fixed to the toothed area of ​​the model base, and the two side walls are provided with insertion slots;

[0009] There are two side bodies, each equipped with a premolar and a molar. A sliding groove is provided at the bottom of the side body, and a snap-fit ​​block is fixed to the inner wall of the sliding groove. The stabilizing strip can slide into the sliding groove, and the snap-fit ​​block abuts against the inner wall of the insertion groove. The side body can be installed and fixed with the middle body.

[0010] When the side body abuts against the middle body, the side body connects to the side wall of the model base, and the side body connects to the side wall of the middle body.

[0011] Optionally, a positioning groove is provided at the bottom of the intermediate body, and a positioning block is fixed on the upper surface of the model base. When the intermediate body abuts against the model base, the positioning block is located in the positioning groove, and the intermediate body cannot rotate at this time.

[0012] The bottom of the intermediate body has a fixing groove with threads distributed on the inner wall of the fixing groove. The bottom of the model base has a fixing hole that communicates with the fixing groove. The fixing hole allows the bolt to pass through and connect with the fixing groove through the thread.

[0013] Optionally, the side body has a fixed insertion rod on its side wall, and the middle body has an insertion hole on its side wall. When the side body is installed on the model base, the insertion rod is inserted into the insertion hole.

[0014] Optionally, the plug rod and the plug hole are interference-fitted.

[0015] Optionally, a first magnet is fixed to the side wall of the side body, and a second magnet is embedded in the side wall of the middle body, and the first magnet and the second magnet can attract each other.

[0016] Optionally, the sidewall of the intermediate body is provided with an embedding groove, in which the second magnet is embedded, and the first magnet can be inserted into the embedding groove to attract the second magnet.

[0017] Optionally, an elastic block is fixed to the top wall of the sliding groove. After the stabilizing strip is pressed against the elastic block, the snap-fit ​​block can slide into the insertion groove.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The side body and the middle body divide the oral cavity model into three parts. The molars and premolars on both sides are on the side body, and the incisors and canines are on the middle body. The side body can be detached, and the side body of the corresponding pathological model can be selected and installed on the model base according to teaching needs. The plug-in design of the side body can effectively improve the efficiency of side body installation and disassembly.

[0020] 2. The intermediate body can also be detachably installed on the model base by bolts, thereby realizing the replacement of the intermediate body model. At the same time, after the intermediate body is installed, the side body can be further fixed by the grooves on both sides of the side body, improving the stability of the side body fixation.

[0021] 3. The addition of an elastomer can effectively increase the frictional resistance after the side body is installed, thereby improving the stability of the side body after installation, so that the side body can be installed and removed only after being pressed down.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a simulated oral cavity model.

[0029] Example 1

[0030] refer to Figure 1 The simulated oral cavity model includes a base 1, a central body 2, and two lateral bodies 3. The base 1 corresponds to the central portion of the jawbone as the incisor region 11, and the portions on either side of the jawbone as the molar regions 12. The central body 2 is located in the incisor region 11, and the lateral bodies 3 are located in the molar regions 12. The incisors and canines are mounted on the central body 2, and the molars and premolars are mounted on the lateral bodies 3.

[0031] refer to Figure 2 and Figure 3 The intermediate body 2 has a positioning groove 21 at its bottom. A positioning block 111 is fixed at the position of the incisor area 11 on the upper surface of the model base 1. When the intermediate body 2 is installed in the incisor area 11, the positioning block 111 is located in the positioning groove 21, so that the intermediate body 2 cannot rotate. The intermediate body 2 has a fixing groove 22 at its bottom. The inner wall of the fixing groove 22 is threaded. The bottom of the model base 1 has a fixing hole 13 that communicates with the fixing groove 22. The fixing hole 13 allows the screw of the bolt to pass through and be threaded into the fixing groove 22, so as to realize the installation of the intermediate body 2 on the model base 1. This enables the replacement of the intermediate body 2 for different pathological models and saves the cost of teaching models.

[0032] A stabilizing plate 121 is installed on the molar area 12 on the upper surface of the model base 1. Insertion slots 1211 are formed on both side walls of the stabilizing plate 121. A sliding groove 31 is formed at the bottom of the side body 3, allowing the stabilizing plate 121 to slide into the sliding groove 31 for installation. A locking block 311 is fixed to the inner wall of the sliding groove 31, abutting against the inner wall of the insertion groove 1211 to prevent the side body from being pulled upwards. An elastic block is fixed to the top wall of the sliding groove 31. After the stabilizing plate 121 is pressed against the elastic block, the locking block 311 can slide into the insertion groove. The elastic block can be made of a material with resilience, such as sponge; in this embodiment, the elastic block is a bent spring sheet.

[0033] refer to Figure 2 The side body 3 has a fixed insertion rod 32 on its side wall, and the middle body 2 has an insertion hole 23 on its side wall. When the side body 3 is installed on the model base 1, the insertion rod 32 is inserted into the insertion hole 23, and the insertion rod 32 and the insertion hole 23 are interference-fitted. After the side body 3 is installed, its side wall abuts against the side wall of the middle body 2. At this time, the side body 3 is connected to the side wall of the model base 1 and the side wall of the middle body 2. After the middle body 2 is installed, the insertion rod 32 can be inserted into it through the insertion hole 23, thereby realizing the installation and fixation of the side body 3. At the same time, the insertion rod 32 can also fix the middle body 2 after being inserted into the insertion hole 23. The detachable setting of the side body 3 also allows the side body 3 of the model with different pathological characteristics to be replaced and installed according to teaching needs.

[0034] The implementation principle of Embodiment 1 of this application is as follows: The intermediate body 2 and side body 3 with different pathological characteristics can be replaced on the model base 1 according to teaching needs. This not only enables the teaching demonstration of different oral pathologies but also effectively reduces the cost of purchasing teaching models. When installing the side body 3, it is pressed onto the stabilizing strip 121, causing the elastic block to be compressed. The side body 3 then slides towards the intermediate body 2, and the snap-fit ​​block 311 is inserted into the insertion slot 1211. After the insertion rod 32 is inserted and fixed in the insertion hole 23, it is fixed to the intermediate body 2, thus achieving the installation and fixation of the side body 3. When the intermediate body 2 needs to be replaced, the side body 3 also needs to be disassembled. Then, the bolts fixing the intermediate body 2 are removed before replacing the intermediate body 2.

[0035] Example 2

[0036] refer to Figure 4 The difference between Embodiment 2 and Embodiment 1 is that: a first magnet 33 is fixedly provided on the side wall of the side body 3, and an embedding groove 24 is provided on the side wall of the intermediate body 2, in which a second magnet 241 is embedded. After the side body 3 is installed, the first magnet 33 will extend into the embedding groove 24 and be attracted and fixed to the second magnet 241.

[0037] The difference in the implementation principle of Embodiment 2 of this application is that after the side body 3 is inserted into the stabilizing strip 121, it is fixed by mutual attraction between the first magnet 33 and the second magnet 241, which improves the efficiency of installation and disassembly of the side body 3. At the same time, the setting of the embedding groove 24 can also effectively improve the stability of the installation of the intermediate body 2.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
