Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, specifically to a novel oral cavity opening device. Background Technology

[0002] In clinical orthodontic practice, mouth openers are commonly used auxiliary tools for bonding brackets. To achieve the best orthodontic results, orthodontic attachments often need to be bonded to the second permanent molars or even the third molars. However, currently used mouth openers mainly open the labial and buccal mucosa in the front of the mouth, providing almost no support to the mucosa in the molar area. This makes it difficult for the buccal tubes of the second permanent molars and third molars, as well as other attachments, to be accurately, smoothly, and securely positioned, thus affecting the smooth progress of orthodontic treatment.

[0003] Meanwhile, most commonly used mouth openers are made of plastic, which is easily damaged and deformed during high-temperature and high-pressure sterilization. Therefore, a metal mouth opener has been designed, with the following structure... Figure 1 As shown, it includes a left support 1 and a right support 2. A handle 3 is fixedly connected to one end of both the left and right supports 1 and 2. The other ends of the left and right supports 1 and 2 are fixedly connected by upper and lower support beams 4', which are composed of multiple U-shaped bodies connected sequentially. The inventors of this application found through clinical use that the opening size of existing mouth openers is difficult to adjust during use, and sometimes causes discomfort to patients when putting on or taking off the mouth open. Utility Model Content

[0004] In view of the technical problem that the opening size of existing mouth openers is difficult to adjust during use and sometimes causes discomfort to patients when putting on or taking off, this utility model provides a new type of mouth opener.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A novel opening device includes a left support and a right support. A handle is fixedly connected to one end of each support, and upper and lower horizontal supports are fixedly connected to the other ends of each support. The upper and lower horizontal supports connected to the left support and the upper and lower horizontal supports connected to the right support are positioned opposite each other. A left support rod is fixedly connected to the handle connected to the left support, and a right support rod is fixedly connected to the handle connected to the right support. Opposite support rods are fixedly connected to the bodies of both the left and right support rods. One support rod has an external thread on its surface, and a rotatable connecting rod is fixedly sleeved on the other support rod. The connecting rod has a threaded groove inside, and the externally threaded support rod extends into the threaded groove inside the connecting rod for a threaded connection.

[0007] Compared with the prior art, the novel mouth opening device provided by this utility model is used by placing the device into the patient's mouth, with the left and right supports positioned on the left and right sides of the mouth respectively. The upper and lower lips are supported by the upper and lower horizontal supports, thus improving the exposure of the oral cavity and facilitating operation. Then, rotating the connecting rod located outside the mouth causes the two supports on the left and right struts to move in opposite directions or relative to each other. This, in turn, moves the left support fixedly connected to the left strut and the right support fixedly connected to the right strut left and right, thereby changing the distance between the left and right supports to accommodate patients with different oral cavity sizes. This opening size adjustment can accommodate different oral cavity widths, and can also be used when the mouth is small, then increased in width, thus better adjusting the support effect on the buccal mucosa. This method makes it more comfortable for patients to put on and take off the mouth opening device.

[0008] Furthermore, the left support, right support, handle, and upper and lower cross supports are all made of elastic medical materials.

[0009] Furthermore, the upper and lower horizontal supports are cylindrical.

[0010] Furthermore, the upper and lower horizontal supports are cylindrical with threads.

[0011] Furthermore, the cylindrical upper and lower horizontal supports are provided with flexible protective sleeves.

[0012] Furthermore, the left or right support rod has a storage groove inside the end away from the handle, and a connecting section is provided at the end of the right or left support rod away from the handle, the connecting section being slidably inserted into the storage groove.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please refer to Figure 2 As shown, this utility model provides a novel mouth opening device, including a left support 1 and a right support 2. A handle 3 is fixedly connected to one end of each of the left and right supports 1 and 2, and upper and lower horizontal supports 4 are fixedly connected to the other ends of each. The upper and lower horizontal supports 4 connected to the left support 1 and the right support 2 are positioned opposite each other to better support the upper and lower lips of the oral cavity. A left support rod 5 is fixedly connected to the handle 3 connected to the left support 1, and a right support rod 6 is fixedly connected to the handle 3 connected to the right support 2. Opposite support rods 7 are fixedly connected to the rods of both the left and right support rods 5 and 6. One of the two support rods 7 has an external thread 71 on its surface, and a rotatable connecting rod 8 is fixedly sleeved on the other support rod 7. The connecting rod 8 is specifically fixedly sleeved on the other support rod. The connecting rod 8 has a threaded groove inside. The support rod 7 with the external thread 71 extends to the threaded groove inside the connecting rod 8 for threaded connection. For example, when the support rod 7 fixedly connected to the right support rod 6 has an external thread 71 on its surface, the rotatable connecting rod 8 is fixedly sleeved on the support rod 7 fixedly connected to the left support rod 5, and the support rod 7 with the external thread 71 extends to the threaded groove inside the connecting rod 8 to achieve threaded connection.

[0020] Compared with the prior art, the novel mouth opening device provided by this utility model is used by placing the device into the patient's mouth, with the left and right supports positioned on the left and right sides of the mouth respectively. The upper and lower lips are supported by the upper and lower horizontal supports, thus improving the exposure of the oral cavity and facilitating operation. Then, rotating the connecting rod located outside the mouth causes the two supports on the left and right struts to move in opposite directions or relative to each other. This, in turn, moves the left support fixedly connected to the left strut and the right support fixedly connected to the right strut left and right, thereby changing the distance between the left and right supports to accommodate patients with different oral cavity sizes. This opening size adjustment can accommodate different oral cavity widths, and can also be used when the mouth is small, then increased in width, thus better adjusting the support effect on the buccal mucosa. This method makes it more comfortable for patients to put on and take off the mouth opening device.

[0021] As a specific embodiment, the left support 1, right support 2, handle 3 and upper and lower horizontal supports 4 are all made of existing elastic medical materials, and can be further made of elastic medical stainless steel and other materials. Thus, they have suitable mechanical properties, corrosion resistance, biocompatibility (friendly to human tissues and not likely to cause allergic or rejection reactions) and safety, making them very suitable for use in human oral medicine.

[0022] For a specific embodiment, please refer to Figure 2 As shown, the upper and lower horizontal supports 4 are cylindrical, and preferably, threads are provided on the surface of the cylindrical upper and lower horizontal supports 4, which can better support the lips on both sides of the mouth.

[0023] As a specific embodiment, the cylindrical upper and lower horizontal supports 4 are provided with a flexible protective sleeve (not shown in the figure), which can improve the comfort of the upper and lower horizontal supports 4 for the lip support.

[0024] For a specific embodiment, please refer to Figure 2 As shown, the left support rod 5 or the right support rod 6 has a storage groove inside the end away from the handle 3, and a connecting section is provided at the end of the right support rod 6 or the left support rod 5 away from the handle 3. The connecting section is slidably inserted into the storage groove. For example, when the storage groove is provided inside the end of the right support rod 6 away from the handle 3, the connecting section is provided at the end of the left support rod 5 away from the handle 3. The connecting section is slidably inserted into the storage groove. Thus, when the connecting rod 8 rotates and causes the two support rods 7 on the left and right support rods to move in opposite directions or relative to each other, the connecting section slides in the storage groove, thereby making the left and right movement of the left and right supports more stable.

[0025] As a specific embodiment, those skilled in the art can also provide external threads 71 ​​on the surfaces of both support rods 7, and make the thread directions on the surfaces of the two support rods 7 opposite. Then, a connecting rod 8 with internal threads is sleeved on the threaded surfaces of the two support rods 7. Thus, when the connecting rod 8 is rotated, the connecting rod 8 will simultaneously drive the two support rods 7 to rotate. Since the thread directions on the surfaces of the two support rods 7 are opposite, the two support rods 7 will move to the opposite side or to the opposite side, thereby expanding or shrinking the opening width more quickly.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
