Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, more specifically to the field of orthodontic appliances, and particularly to a device for training oral and facial muscle function. Background Technology
[0002] In the field of orthodontic treatment, research has shown that muscles have a crucial impact on the stability of orthodontic treatment, and in some cases, muscle problems are the cause of oral problems. Ignoring muscle problems may lead to ineffective treatment or relapse after treatment. Orofacial myofunctional therapy (OMT) is a multidisciplinary comprehensive treatment method for patients with abnormalities in their orofacial muscles and functions, involving assessment, diagnosis, prevention, and treatment. Its mechanism involves re-education of the neuromuscular system of the orofacial region, promoting normal development of craniofacial structures and coordinated stability of the orofacial system function; it is a treatment method that focuses on the cause of the disease.
[0003] In clinical practice, vestibular shields are commonly used for orofacial muscle function training. They can block contact between the lip and cheek muscles and the teeth and jaws, breaking bad habits such as mouth breathing, lip biting, and thumb sucking. This prevents lip-biting individuals from placing their lower lip on the lingual side of their upper incisors, and prevents thumb-sucking individuals from putting their fingers in their mouths. It can also help mouth-breathing patients get used to mouth-closing breathing, thus eliminating unfavorable muscle pressure. Vestibular shield products are mostly general-purpose products, mass-produced, and typically include different sizes such as S, M, and L. Clinicians need to select the appropriate size based on the individual patient's oral morphology. Clinics usually stock different sizes of vestibular shield products in advance. However, the following situation inevitably arises: if the clinic's patients mostly require a certain size, it will result in a surplus of vestibular shield products, leading to inventory buildup, which is detrimental to the clinic's inventory management and increases costs.

[0026] (2) By providing an easily separable first weak connection between the main body and the separable part, or between two adjacent separable parts, this utility model makes it easy to separate the separable part from the main body or another adjacent separable part when separating the separable part, without causing damage to the separated sub-barrier screen, which is convenient for clinicians to use.
[0027] (3) By setting several sub-separable parts and several sub-separation guide parts between the main body and the separable part, this utility model can achieve fine adjustment of different specifications and models of oral and facial muscle function training devices by breaking different sub-separation guide parts. It can meet and adapt to the fine adjustment of different patients for the same specification and model of oral and facial muscle function training device, increase the comfort of patients when wearing it, increase wearing compliance, and thus improve the treatment effect.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of the invention. However, the technical solutions claimed by this utility model can be implemented even without these technical details and with various variations and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this utility model.
[0042] The directional terms "up," "down," "left," and "right" used in this article refer to the directions shown in the accompanying drawings and do not imply any special limitations.
[0043] In this article, different designations are used for the same structural component to facilitate the description of components in different locations. This does not mean that structural components with different designations necessarily have different structural characteristics. For example... Figure 2 In the text, 21 and 22 are used to indicate two separable parts. This is for the convenience of referring to separable parts at different locations in this article, and does not necessarily mean that the two separable parts have different structural features.
[0044] This application provides an orofacial muscle function training device, which is a generally C-shaped barrier screen used to block contact between the lip and cheek muscles and the teeth and jaws. It includes a generally C-shaped main body, n separable parts circumferentially disposed on the outside of the main body, and n separation guide parts disposed between the main body and the separable parts or between two adjacent separable parts. The separation guide parts guide the separable parts to separate from the main body, or guide adjacent separable parts to separate, so as to form n generally C-shaped first sub-barrier screens of various sizes, where n≥1. As the background technology shows, in clinical practice, different patients have different oral conditions and sizes, requiring different sizes of orofacial muscle function training devices. Orthodontic manufacturers typically produce different sizes and models of orofacial muscle function training devices for clinicians to choose from. Clinicians then need to select the appropriate size and model based on the patient's oral size. This necessitates clinics to stock different sizes and models of orofacial muscle function training devices in advance. However, this selection may lead to a higher demand for a particular size and model, resulting in redundancy and product stockpiling of other sizes and models. Using the orofacial muscle function training device provided in this application, the separable part can be guided to separate from the main body by the separation guide, or the adjacent separable parts can be guided to separate, thus forming an orofacial muscle function training device of the size and model required by the patient. Clinicians no longer need to stock multiple sizes and models of orofacial muscle function training devices in advance. This structural design has several advantages. First, by separating the different separable parts through the separation guide section, first sub-barrier screens of different specifications can be formed, which are simple and easy to separate and can be adapted to the needs of different patients. Second, clinics do not need to stock different specifications and models of oral and facial muscle function training devices, which reduces the difficulty of planning and coordination, eliminates the need to manage multiple specifications and models of oral and facial muscle function training devices separately, and avoids redundancy of various specifications and models of oral and facial muscle function training devices, thus avoiding product backlog and increased costs.
[0045] Example 1
[0046] Please refer to Figure 1 and Figure 2 As shown. In this embodiment, the orofacial muscle function training device 100 is a roughly C-shaped barrier screen worn in the oral cavity, which can block the contact between the lip and cheek muscles 200 and the jaw 300. In this embodiment, n=2. The orofacial muscle function training device includes a generally C-shaped main body 10, two detachable parts (21, 22) arranged circumferentially on the outside of the main body 10, and two separation guide parts (31, 32). One separation guide part 31 is located between the main body 10 and the detachable part 21 located near the main body 10, and the other separation guide part 32 is located between two adjacent detachable parts (21, 22). The separation guide part 31 can guide the main body 10 to separate from the detachable part 21, and the separation guide part 32 can guide the two adjacent detachable parts (21, 22) to separate. Two different specifications of orofacial muscle function training devices can be formed through the two separation guide parts (31, 32). In addition, the generally C-shaped barrier screen without any separation operation can be added to realize the conversion of three specifications of orofacial muscle function training devices. Specifically, in this embodiment, by retaining the two separation guides (31, 32) without any separation, a facial muscle function training device of specification L can be formed as a whole. The separation guide 32 guides the two adjacent separable parts (21, 22) to separate, for example, by breaking the separation guide 32 to separate the separable part 22 located away from the main body 10, thus forming a first sub-blocking screen after separation. The first sub-blocking screen includes the main body 10, the separation guide 31, and the separable part 21. At this time, the first sub-blocking screen forms a facial muscle function training device of specification M. The separation guide 31 guides the separable part 21 to separate from the main body 10, for example, by breaking the separation guide 31 to separate the separable part 21. The main body 10 obtained after separation forms a facial muscle function training device of specification S. As can be seen, by setting two separable parts (21, 22) and two separation guide parts (31, 32), two first sub-barrier screens of different specifications can be formed; plus the generally C-shaped barrier screen without any separation operation; this embodiment can easily realize the conversion of three specifications of oral and facial muscle function training devices to suit patients with different needs.
[0047] Further reading is available here. Figure 2As shown, in order to ensure that the outer periphery of the orofacial muscle function training devices of different specifications and models has a smooth curved edge, in some embodiments, the two adjacent separation guides (31, 32) are designed to be set at a first preset distance L1. In some preferred embodiments, the first preset distance L1 can be 3mm-5mm. Such a design of the first preset distance L1 value can cover the needs of most patients in clinical practice and has wide applicability. Specifically, the first preset distance L1 is the distance between any point A on one of the separation guides 31 and the corresponding point A' on the other adjacent separation guide 32. To further explain, point A is arbitrarily selected on the separation guide 31. The point A' that intersects the separation guide 32 with the tangent direction perpendicular to the separation guide 31 and passing through point A is the corresponding point on the separation guide 32 corresponding to point A. The distance between point A and point A' is the first preset distance L1 described in this application. In this design, the first preset distance L1 between any two points (A, B) on the separation guide 31 is equal. Specifically, the distance between any point A on the separation guide 31 and its corresponding point A' on the adjacent separation guide 32 is equal to the distance between any point B on the separation guide 31 and its corresponding point B' on the adjacent separation guide 32. That is, the radial dimension of the circumference of the separable part 21 is equal everywhere. This structural design ensures that each specification of the orofacial muscle function training device formed by separating any of the separation guides has a relatively smooth outer peripheral edge, avoiding wavy outer peripheral edges that could cause patient discomfort.
[0048] Furthermore, the first preset distance value between any two adjacent separation guides is equal, that is, the radial dimensions of each separable part are consistent and are all set at the first preset distance L1. This structural design can ensure that the radial dimensions of several separable parts are equal, that is, the difference in radial dimensions between several specifications of oral and facial muscle function training devices is equal. For example, the distance between any two points (A, B) on the separation guide 31 and the corresponding points A', B' on the adjacent separation guide 32, and the distance between point D on the separation guide 32 and the corresponding point D' on the outermost contour line of the oral and facial muscle function training device are equal, all of which are the first preset distance L1. Thus, the equal first preset distance setting is beneficial to production and processing. For example, in the design, the outer contour line of the main body 10 can be offset to the outer edge at equal distances of the first preset distance L1, or the outer contour line of the separable part 21 can be offset to the outer edge at equal distances of the first preset distance L1. In other embodiments, the spacing between any two adjacent separation guides is not equal, that is, the radial dimensions of the separable parts are different. For example, the difference in radial dimensions between two adjacent sizes of oral and facial muscle function training devices is not equal. For example, the difference in radial dimensions between size L and size M oral and facial muscle function training devices is greater than or less than the difference in radial dimensions between size M and size S oral and facial muscle function training devices. All of these can be designed according to actual needs.
[0049] Further reading is available here. Figure 2 And refer to Figure 3As shown, the separation guide 31 is a first weak connection part that facilitates the separation of the main body 10 and the separable part 21, or the separation guide 32 is a first weak connection part that facilitates the separation of two adjacent separable parts (21, 22), so that when a force greater than a predetermined value is applied, the separable part 21 is detached from the main body 10, or the separable part 22 is detached from the separable part 21. The first weak connection can be implemented based on the geometry of the weakened connection or by introducing a weakening material into the connection. Implementing the first weak connection based on the geometry of the weakened connection means using a relatively weak connection, with a mechanical strength lower than that of the main body and the separable part itself. This allows it to be broken with a smaller force without damaging the main body 10 or the separable parts (21, 22). Introducing a weakening material into the first weak connection means using different materials to process different parts during the production of the orofacial muscle function training device. For example, the main body 10 and the separable parts (21, 22) can be produced using a material with higher hardness, while the first weak connection is made of a material with lower mechanical strength. This allows the separable part 21 to be easily detached from the main body 10 or the adjacent separable parts (21, 22) through the first weak connection formed by the material with lower mechanical strength.
[0050] In this embodiment, gaps or cuts are spaced out in the circumferential direction of the first weak connection to reduce its mechanical strength. In a preferred embodiment, the first weak connection is constructed using... Figure 2 and Figure 3 The layered mesh perforated structure shown can stably connect the main body 10 and the separable part 21 or two adjacent separable parts (21, 22) without breaking during transportation. When it is necessary to separate the separable part 21 or the separable part 22, the layered mesh perforated structure can break when a force greater than a predetermined value is applied. Preferably, please refer to [reference needed]. Figure 4 As shown, the thickness h of the lip of the layered mesh perforated structure is less than or equal to the thickness H of the lip of the sub-barrier screen. In another preferred embodiment, the thickness h of the lip of the layered mesh perforated structure is 0.1mm-0.5mm. The inventor has verified that such a thickness ratio and thickness range can not only ensure a stable connection between the main body 10 and the separable part 21 or two adjacent separable parts (21, 22) without breakage during transportation, but also ensure that when the separable part 21 or the separable part 22 needs to be separated, the layered mesh perforated structure can break when a force greater than a predetermined value is applied to it.
[0051] Furthermore, to meet the functional requirements of this layered mesh perforated structure, please continue reading... Figure 3 As shown, in this application, two adjacent gaps or cuts 1 are spaced apart by a second preset distance L2, wherein the second preset distance L2 is 0.1mm-1mm. Specifically, a connector 2 is provided between two gaps or cuts 1. In this application, the second preset distance L2 between two adjacent gaps or cuts 1 is the characteristic radial dimension of the connector 2. The inventor has verified that the size range of the second preset distance L2 can meet the requirement of stably connecting the main body 10 and the separable part 21 or two adjacent separable parts (21, 22) without breaking during transportation. When it is necessary to separate the separable part 21 or the separable part 22, when a force greater than a predetermined value is applied to the layered mesh hollow structure, the layered mesh hollow structure can break.
[0052] Furthermore, when the separation guide 32 is broken to form a facial muscle function training device of specification M, the M-type facial muscle function training device includes a main body 10, a separable part 21, and a separation guide 31 (first weak connection part) connecting the main body 10 and the separable part 21. Since the mechanical strength of the first weak connection part is less than that of the main body 10 and the separable part 31, when the M-type facial muscle function training device is used as a whole, the lower mechanical strength at the first weak connection part will affect the overall mechanical strength of the M-type facial muscle function training device, thereby affecting the patient's treatment effect. Therefore, please refer to... Figure 5As shown, in this embodiment, the orofacial muscle function training device further includes a first reinforcing part 40. The first reinforcing part 40 has several protrusions 41 whose outer contour shape matches the inner contour shape of the gap or incision. The first reinforcing part 40 matches the first weak connecting part to enhance the mechanical strength of the first weak connecting part. The first reinforcing part 40 is detachably connected and can be located on one side of the first weak connecting part facing the patient's lip / cheek or tongue side. It is understood that when the first reinforcing part 40 is located on both sides of the first weak connecting part facing the patient's lip / cheek and tongue side, the effect of enhancing the mechanical strength of the first weak connecting part is better. Simultaneously, it can also close the hollow structure at the gap or incision, not only enhancing the mechanical strength at that location but also preventing the accumulation of oral debris at that location, or facilitating the cleaning of oral debris, thereby improving the patient's oral hygiene. Of course, this description only refers to the location of one separation guide 31. When the orofacial muscle function training device has multiple separation guides, one or more of the separation guides can be provided with the first reinforcing part 40 described in this embodiment. Specific cases will not be listed here.
[0053] Further, please see Figure 6 As shown, the first reinforcing portion 40 further includes a covering layer 50, which is connected to both ends of the sidewall of the first reinforcing portion 40 away from the first weak connecting portion. The covering layer 50 covers the buccal or lingual surfaces of the main body portion 10 and the separable portion 21 connected to both sides of the separating guide portion 31, or simultaneously covers both the buccal and lingual surfaces of the main body portion 10 and the separable portion 21 connected to both sides of the separating guide portion 31. In other embodiments, the covering layer may also cover the buccal or lingual surfaces of the two separable portions connected to both sides of the separating guide portion, or simultaneously cover both the buccal and lingual surfaces of the two separable portions connected to both sides of the separating guide portion. The covering layer 50 serves two purposes: firstly, it further connects the oral and facial muscle function training device into a complete whole, improving the overall mechanical strength; secondly, it covers the groove or gap between the first weak connection part and the main body 10 and the separable part 21, further preventing the accumulation of dirt in the oral cavity at that location, or facilitating the cleaning of dirt in the oral cavity, thereby helping to improve the patient's oral hygiene.
[0054] Example 2
[0055] Please refer to Figure 7 and Figure 8As shown. To address the technical problem this utility model aims to solve, this utility model also provides an orofacial muscle function training device 100. The difference between this embodiment and Embodiment 1 is that the separation guide portion is a circumferentially concave or convex shearing indicator line 30 disposed on the lip / cheek or tongue side of the orofacial muscle function training device, used for shearing along the shearing indicator line 30 to form sub-barrier screens of different specifications. The shearing indicator line 30 is a continuously arranged concave or convex structure (e.g., ...). Figure 7 (As shown). In other embodiments, the shearing indicator line 30 may also be a plurality of spaced concave and / or convex structures (e.g., Figure 8 As shown in the diagram, the shearing indicator line 30 can be partly an outwardly convex structure protruding from the lip and buccal side and / or tongue side of the orofacial muscle function training device, and partly an inwardly concave structure within the lip and buccal side and / or tongue side of the orofacial muscle function training device. Adjacent outwardly convex structures, inwardly concave structures, or between the outwardly convex and inwardly concave structures are spaced apart by a third preset distance L3. In another preferred embodiment, the third preset distance L3 is 0.1mm-1mm. This spacing not only ensures clear indication of the required shearing path but also saves on the processing materials of the orofacial muscle function training device 100, such as medical-grade silicone material.
[0056] Example 3
[0057] Please refer to Figure 9 As shown. The orofacial muscle function training device 100 in this embodiment includes a generally C-shaped main body 10, three detachable parts (21, 22, 23) circumferentially disposed on the outside of the main body 10, and three separation guide parts (31, 32, 33). By breaking the separation guide parts at different locations, three different specifications of the first sub-barrier screen can be formed; together with the generally C-shaped barrier screen without any separation operation, this embodiment can easily realize the conversion of four specifications of orofacial muscle function training devices to suit patients with different needs. The only difference between this embodiment and embodiment 1 is the number of detachable parts and separation guide parts (n=3 in this embodiment). Other technical features are the same as in embodiment 1 and will not be repeated here.
[0058] Of course, it is understood that the number of the separable part and the separation guide part can also be 1, 4, 5, or 6, etc., forming 1, 4, 5, or 6 different specifications of the first sub-barrier screen; plus the roughly C-shaped barrier screen that does not perform any separation operation; thus, it is very convenient to switch between two, five, six, or seven specifications of oral and facial muscle function training devices. Apart from this, it is consistent with Embodiment 1, and will not be elaborated further in this article.
[0059] Example 4
[0060] Clinically, clinicians have found that even patients fitted with the same size device may have slight inconsistencies in the dimensions within their oral cavity. To achieve a better fit for each patient's mouth and provide a superior wearing experience during treatment, this embodiment differs from Embodiment 1 in that the orofacial muscle function training device 100 in this embodiment further includes several sub-separable parts and sub-separable guide parts circumferentially disposed between the main body and the separable part, to meet and adapt to the slightly different needs of different patients. Specifically, please refer to... Figure 10 As shown, several sub-separation guides and several sub-separable parts are also provided between the main body and the separable part. Specifically, taking the formation of different fine-tuned specification model S as an example, two sub-separation guides (61, 62) are offsetly provided on the outer periphery of the main body 10. One of the sub-separation guides 61 is located adjacent to the outer periphery of the main body 10, and the sub-separable part 71 is located between the two sub-separation guides (61, 62). Another sub-separable part 72 is provided on the outer side of the other sub-separation guide 62 away from the main body 10. The separation guide 31 is located on the outer periphery of the sub-separable part 72 away from the main body 10, and the separation guide 21 is located adjacent to the separation guide 31. When the separation guide 31 breaks, the remaining part includes the main body 10, the two sub-separation parts (71, 72), and the two sub-separable parts. The sub-separation guides (61, 62) separate the second sub-barrier, which forms a standard S-type orofacial muscle function training device. When the sub-separation guide 62, which is away from the main body 10, breaks off, the remaining part includes the main body 10, one sub-separation guide 61, and one sub-separable part 71. The resulting second sub-barrier can form an S'-type orofacial muscle function training device. When the sub-separation guide 61 breaks off, the remaining part only includes the main body 10. The resulting second sub-barrier can form an S”-type orofacial muscle function training device. This allows for the rapid formation of various finely tuned S-type orofacial muscle function training devices, providing patients and clinicians with more options. Fine-tuning of other types of orofacial muscle function training devices is also performed in this way, and will not be elaborated here.
[0061] In other embodiments, the sub-separation guide and the sub-separable portion may be positioned such that the sub-separation guide is located immediately adjacent to the outer periphery of the separable portion. For details, please refer to [link to relevant documentation]. Figure 11As shown, taking the formation of different finely tuned specification M as an example, this embodiment provides two sub-separable parts and two sub-separation guide parts for specification M, which can form two different specifications of second sub-barrier screens. Two sub-separable parts (73, 74) are provided between the two separable parts (21, 22). The two sub-separable parts (73, 74) are circumferentially arranged around the outer periphery of the separable part 32, and are connected by a sub-separation guide part 63. The sub-separable part 74 closer to the separable part 22 is connected to the separable part 22 by another sub-separation guide part 64. When the sub-separation guide 2 breaks, the remaining portion includes the main body 10, the two sub-separable portions (73, 74), the separation guide 32 connecting the main body 10 and the sub-separable portion 71 near the main body 10, and the sub-separation guide 63 connecting the two sub-separable portions (73, 74), forming a second sub-barrier with a standard size M; when the sub-separation guide 63 breaks, the remaining portion includes the main body 10, the sub-separable portion 73, and the separation guide 32 connecting the main body 10 and the sub-separable portion 73, forming a second sub-barrier with a standard size M'. When the screen breaks from the separation guide 32, the remaining part only includes the main body 10, at which point a second sub-barrier screen of specification M” can be formed. It is evident that the inventive concept of this embodiment lies in setting several sub-separable parts and sub-separation guides between the main body and the separable part, or between two different separable parts, aiming to achieve fine-tuning of different specifications of orofacial muscle function training devices by breaking different sub-separation guides. Various positions and orders between the sub-separation guides and the sub-separable parts and the main body and the separable part, and the separation guides, can all realize the technical means of the inventive concept and are all within the protection scope of this utility model.
[0062] In other embodiments, the number of the separable sub-parts and the separating guide sub-parts can be 1, 3, 4, or 5, etc., forming different specifications and models of orofacial muscle function training devices with different degrees of fine-tuning. Specifically, when the number of both the separable sub-parts and the separating guide sub-parts is 1 (not shown), the separating guide sub-parts are disposed between the main body and the separable sub-parts, or the separable sub-parts are disposed between the separable sub-parts and the separable sub-parts.
[0063] Furthermore, in this embodiment, please continue to refer to... Figure 10 and Figure 11As shown, the sub-separation guide can be an indicator line circumferentially concave or convex on the lip / cheek or lingual side of the orofacial muscle function training device, used to cut along the indicator line to form a second sub-barrier screen with different fine-tuning degrees in various specifications and models. The indicator line is a continuously arranged concave or convex structure, such as... Figure 10 The structure of the sub-separation guides (61, 62) is shown. In other embodiments, the indicator lines are multiple spaced concave and / or convex structures, such as... Figure 11 The structure of the sub-separation guide (63, 64) shown is as follows: Specifically, the indicator line may be partly an outwardly convex structure protruding from the lip and buccal side and / or tongue side of the orofacial muscle function training device, and partly an inwardly concave structure concave from the lip and buccal side and / or tongue side of the orofacial muscle function training device. The structural features of the inwardly concave structure or the outwardly convex structure are consistent with the features of the inwardly concave structure or the outwardly convex structure in Embodiment 2, and will not be described again here.
[0064] In other embodiments, the sub-separation guide may also be a second weak connection that facilitates the separation of the two components connected to the sub-separation guide. The two components connected to the sub-separation guide may be a main body and a sub-separable portion, or two adjacent sub-separable portions, so that when a force greater than a predetermined value is applied, the sub-separable portion detaches from the main body or the sub-separable portion. The structural features of the second weak connection are consistent with those of the first weak connection in Embodiment 1, and will not be described separately here.
[0065] Similarly, since the mechanical strength of the second weak connection is low, in order to increase the overall strength of the orofacial muscle function training device, for example, as in this embodiment, with Figure 10 In the description of the orofacial muscle function training device of specification model S, when one of the sub-separation guides 62, which is located between the two sub-separable parts (71, 72), breaks, the remaining part includes the main body 10, one sub-separation guide 61, and one sub-separable part 71, thus forming a second sub-barrier screen of specification model S'. At this time, a second reinforcing part is provided at the position of the sub-separation guide 61, which is adapted to the gap or cut on the sub-separation guide 61, thereby enhancing the overall mechanical strength of the second sub-barrier screen of specification model S'. The structural features of the second reinforcing part are consistent with the structural features of the first reinforcing part in Embodiment 1, and will not be described separately here.
[0066] Furthermore, please refer to [the relevant documentation / reference]. Figure 12As shown, two adjacent sub-separation guides are set at a fourth preset distance L4, wherein the fourth preset distance L4 is less than the first preset distance L1. In some preferred embodiments, the fourth preset distance L4 can be 0.5mm-2mm. Such a fourth preset distance L4 setting can meet the fine adjustment within the same specification model without the adjustment range being too large, directly jumping to another specification model. It can meet the needs of patients who cannot be covered in Embodiment 1, and has wider applicability. Specifically, taking the sub-separation guide 66 and the sub-separation guide 67 as examples, the fourth preset distance L4 is the distance between any point G on one of the sub-separation guides 66 and the corresponding point G' on the adjacent sub-separation guide 67. More specifically, the fourth preset distance L4 is the distance between any point G on one of the sub-separation guides 66 and the corresponding point G' on the adjacent sub-separation guide 67. Further, if a point G is arbitrarily selected on one of the sub-separation guides 66, and a line perpendicular to the tangent at point G is extended towards the adjacent sub-separation guide 67, the point G' intersecting the other sub-separation guide 67 is the corresponding point on the other sub-separation guide 67. The distance between point G and point G' is the fourth preset distance L4 described in this application. Wherein, the value of the fourth preset distance L4 corresponding to any two points (G, R) on the sub-separation guide 66 is equal, that is, the distance between any point G on the sub-separation guide 66 and the corresponding point G' on another adjacent sub-separation guide 67 is equal to the distance between any point R on the sub-separation guide 66 and the corresponding point R' on another adjacent sub-separation guide 67, both of which are L4.
[0067] Furthermore, the fourth preset distance between any two adjacent sub-separation guides can be equal, meaning the radial dimensions of any two sub-separable parts can be equal, both being L4. For example, the distance between sub-separation guides 65 and 66, and between sub-separation guides 66 and 67, is set at the fourth preset distance L4. This design is beneficial for manufacturing design. During the design process, the outer contour line of the main body 10 can be offset to the outer edge at equal distances from the fourth preset distance L4, or the outer contour line of the sub-separable parts can be offset to the outer edge at equal distances from the fourth preset distance L4. In other embodiments, the distance between any two adjacent sub-separation guides can also be unequal, meaning the radial dimensions of the sub-separable parts are different. For example, the difference in radial dimensions between two adjacent sub-separable parts used for different degrees of fine-tuning is not equal, and this can be designed according to actual needs.
[0068] In other embodiments, the number of sub-separable sections and sub-separation guide sections used for fine-tuning each specification to varying degrees may be inconsistent; please refer to [link to previous document]. Figure 10 and Figure 11 As shown, for example, two sub-separable sections and two sub-separation guide sections are provided between the main body 10 and the separable section 21 near the main body 10, and between the separable section 21 and another adjacent separable section 22. This allows for simultaneous adjustment and selection of three different levels of fine-tuning when forming an S or M size orofacial muscle function training device. Furthermore, three sub-separable sections and three sub-separation guide sections are provided around the periphery of the separable section 32, allowing for simultaneous adjustment and selection of four different levels of fine-tuning when forming an L size orofacial muscle function training device. In clinical practice, this can be adjusted and designed as needed based on a large amount of case data.
[0069] It should be noted that the above embodiments can be freely combined as needed to form different new implementation schemes without causing contradictions.
