[0023] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and do not constitute a limitation on the present application.
[0024] The "up", "down", "left", "right", "front", "back" and other orientation words or position relationships described in the embodiments are based on the orientation relationship in the drawings of the present application, and are only for the convenience of describing the present application and simplifying the description, and are not indicative or implied of the specific orientation, specific orientation structure and operation that the device or element must have, and therefore cannot be understood as a limitation on the content protected by the present application. Figure 3
[0025] In the present embodiment, the depth and height refer to the distance in the left and right directions, and the length refers to the distance in the up and down directions.
[0026] As shown in Figures 3-5 , the present embodiment is an improvement on the existing oral spreader, and the improvement point is to change the connection relationship between the wing plate 3 and the dental pad 1, so that the wing plate 3 can rotate relative to the dental pad 1, so that the wing plate 3 can be switched between abutting against the tongue and abutting against the palate without taking the present embodiment out of the oral cavity.
[0027] As shown in Figure 3 , 4 , the present embodiment includes a dental pad 1 and a wing plate 3, and the wing plate 3 is rotatably arranged on the dental pad 1. The rotatable arrangement is specifically: the wing plate 3 is provided with a clamping block 31 with a circular longitudinal section, and the clamping block 31 includes a first clamping block 311 and a second clamping block 312 fixedly connected; the dental pad 1 is provided with a circular clamping groove 11, and the second clamping block 312 is embedded in the clamping groove 11 and can rotate in the clamping groove 11, and the first clamping block 311 extends out of the clamping groove 11. The dental pad 1 is provided with a baffle 12 for preventing the second clamping block 312 from coming out of the clamping groove 11, and the baffle 12 and the dental pad 1 are an integral structure in the present embodiment.
[0028] In order to enable the wing plate 3 to be adjusted from abutting against the tongue to abutting against the palate, the rotation angle of the wing plate 3 in the embodiment is 180°. As shown in Figure 3 , 4 two limiting blocks 32 are arranged on the wing plate 3, the two limiting blocks 32 are separated by 180°, and the dental pad 1 is provided with a limiting portion for limiting the free rotation of the wing plate 3. Specifically, a groove 13 is arranged on the dental pad 1 at a position corresponding to each of the two limiting blocks 32, and the groove 13 is the limiting portion and can limit the arbitrary rotation of the wing plate 3. The size of the groove 13 is matched with the size of the limiting block 32. Here, the matching means that the length of the groove 13 is equal to or slightly greater than the length of the limiting block 32. When the wing plate 3 has a tendency to rotate, the side wall of the groove 13 can abut against the limiting block 32, so that the wing plate 3 cannot be arbitrarily rotated. In addition, the depth of the groove 13 is less than or equal to the height of the limiting block 32, so as to ensure that the limiting block 32 can be separated from the groove 13 in the later period. Of course, the limiting portion in the embodiment can also use the locking member in the prior art. When the wing plate 3 is rotated, the locking member is used to fix the wing plate 3 and the dental pad 1, so that the wing plate 3 cannot continue to rotate.
[0029] It should be noted that the depth of the clamping groove 11 is greater than the height of the clamping block 31. This structure ensures that the second clamping block 312 can move left and right in the clamping groove 11. In addition, the moving distance of the clamping block 31 in the clamping groove 11 is greater than the moving distance of the limiting block 32 in the groove 13. In other words, when the second clamping block 312 moves left in the clamping groove 11 to abut against the baffle 12, at this time the limiting block 32 completely extends out of the groove 13, and at this time the wing plate 3 can be rotated. When the wing plate 3 is rotated to 180°, the wing plate 3 is pushed right again, so that the limiting block 32 enters the groove 13. Referring to Figure 5 , at this time the wing plate 3 cannot be rotated again.
[0030] It should be noted that in oral treatment, the pressing portion 4 of the wing plate 3 is used to abut against the tongue or the palate. In this state, the tongue or the palate can generate a reaction force on the wing plate 3, so that the second clamping block 312 abuts against the side wall of the clamping groove 11, and thus the wing plate 3 cannot be arbitrarily moved left and right.
[0031] The structure of the dental pad 1 is different from that of the prior art. In the embodiment, the dental pad 1 is provided with the clamping groove 11, the groove 13 and the like, and the remaining parts are the same as those of the prior art, which will not be described here.
[0032] As shown in Figures 3-5 , the end of the wing plate 3 away from the dental pad 1 is provided with a pressing portion 4 for abutting against the tongue or the palate. The pressing portion 4 is a polygonal structure. In the embodiment, the pressing portion 4 includes three edges, and each edge is a curve. Since the pressing portion 4 is integrally arranged with the wing plate 3 in the embodiment, one edge close to the wing plate 3 is not drawn. In the embodiment, the central position of the pressing portion 4 is convex to the tongue, as shown in Figure 3The outer contour of the pressing part 4 is a smooth arched structure. When in use, the bottom of the pressing part 4 can press against the tongue, and the smooth arched structure of the outer contour can improve the patient's comfort.
[0033] Of course, the pressing part 4 can also be quadrilateral, hexagonal, or other shapes, as long as the outer contour is a smooth arched structure. In this embodiment, the center of the pressing part 4 protrudes towards the tongue. When rotated, the bottom of the pressing part 4 will abut against the palate. At this time, the center of the pressing part 4 protrudes towards the palate. See [reference needed]. Figure 5 .
[0034] This embodiment is made entirely of polymer resin material and is integrally formed by 3D printing, which enhances the stability and durability of this embodiment, avoids the risk of loosening that may occur with plug-in connections in the prior art, and improves safety.
[0035] To improve this embodiment, such as Figure 3 , 5 As shown, a pull ring 5 is fixed at one end of the dental pad 1 near the outside of the oral cavity, which makes it easy to use a tool to hook it out of the mouth in this embodiment.
[0036] When using this embodiment, place it between the upper and lower teeth on the jaw and face. The bite force generated when the jaw is relaxed stabilizes the dental pad 1, and the pressing part 4 presses against the tongue. (See also...) Figure 3 This allows for clear exposure of the surgical area while protecting the floor of the mouth from damage by surgical instruments. If it is necessary to protect the soft and hard palate tissues during treatment, pull the wing plate 3 to the left until the limiting block 32 disengages from the groove 13. At this point, rotate the wing plate 3 180° so that the pressing part 4 faces upwards and presses against the palate. See [link to relevant documentation]. Figure 5 In this embodiment, when switching from protecting the floor of the mouth to protecting the soft and hard tissues of the palate, it is not necessary to remove the embodiment from the mouth; simply rotating the wing plate 3 is sufficient. This operation is simple and quick, reducing patient discomfort and improving the doctor's work efficiency.
[0037] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
