Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an oral expander for dental use. Background Technology

[0002] An oral expander, also known as an mouth opener or mouth flareer, is a medical device used to support and expand the oral cavity, and is widely used, especially in dental treatment, orthodontic treatment, and oral examinations.

[0003] Traditional oral expanders are often made of elastic materials to achieve a certain degree of oral expansion. However, due to their limited elasticity, doctors need to change expanders of different sizes in actual clinical applications to meet the diverse oral structures of patients and complex treatment needs. In addition, traditional expanders have limited support and are prone to movement or slippage due to improper operation, which increases the treatment risk.

[0004] Therefore, this application provides an oral expander for dental use to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an oral expander for dental use, which aims to solve the problems mentioned in the background art, such as the limited elasticity of existing oral expanders requiring frequent size changes, and insufficient support making them prone to movement or slippage, which increases the complexity and risk of treatment.

[0006] To achieve the above objectives, this application provides the following technical solution: an oral expander for dental use, comprising two extensions that move closer or further apart from each other, and a support portion fixedly disposed at one end of the extensions for supporting the oral cavity;

[0007] The oral dilator also includes an adjustment mechanism disposed at one end of the extension portion away from the support portion for moving the two extension portions, an airbag fixedly disposed on the side of the support portion near the oral cavity for pressing against the oral cavity, and an inflation component connected to the extension portion for inflating or contracting the airbag.

[0008] The inflation assembly includes an air cylinder positioned on one side of each of the two extensions, a piston that moves laterally within the air cylinder, a push rod passing through the air cylinder near the extension and fixedly connected at both ends to the piston and the extension, and a flexible tube fixedly connected to the end of the air cylinder away from the extension and communicating with the air bladder. The push rod is slidably connected to the air cylinder. By providing an adjustment mechanism, the doctor can flexibly adjust the distance between the two extensions according to the patient's specific oral condition and treatment needs, thereby allowing the two support sections to expand to different degrees to meet different treatment requirements. Simultaneously, by providing the inflation assembly connected to the extensions, when the distance between the two extensions is adjusted through the adjustment mechanism to expand the oral cavity, the push rod synchronously pushes the piston, inflating the air bladder through the flexible tube. This causes the air bladder to expand and press tightly against the oral cavity. This close contact not only improves the stability of the oral dilator but also enhances the support force of the support sections, reducing the risk of the oral dilator slipping during operation. Furthermore, the air bladder design reduces pressure and discomfort on oral tissues.

[0009] Preferably, in order to facilitate the fit of the support portion to the oral cavity, the support portion has an arc-shaped structure or a U-shaped structure; this shape design allows the support portion to fit well to the patient's oral cavity.

[0010] Preferably, to facilitate the use of the oral dilator, a handhold is fixedly provided on one side of each of the two air cylinders, and the handhold is located on the side of the two extensions away from the support; the design of the handhold allows the doctor to hold the handhold, thereby using or adjusting the oral dilator more stably.

[0011] Preferably, in order to facilitate the movement and adjustment of the two extensions, the adjustment mechanism includes a bidirectional screw that runs laterally through the two extensions and is screwed to the two extensions. The two ends of the bidirectional screw are rotatably connected to the handheld bracket. The design of the bidirectional screw allows the doctor to move the two extensions closer or further apart simply by rotating the bidirectional screw, thereby adjusting the distance between the two support parts to achieve different degrees of expansion of the oral cavity.

[0012] Preferably, to facilitate the rotation of the bidirectional screw, the adjustment mechanism further includes a rotating body fixedly sleeved on the bidirectional screw and located between the two extensions; the design of the rotating body provides the doctor with a position to operate the bidirectional screw without the need for other tools, thereby improving the convenience of operation.

[0013] Preferably, in order to enhance the stability of holding the rotating body, the surface of the rotating body is provided with anti-slip texture; the anti-slip texture design can increase the friction between the doctor's hand and the rotating body, effectively preventing the hand from slipping during rotation and improving the stability of operation.

[0014] This dental expander, through the addition of an adjustment mechanism, allows doctors to flexibly adjust the distance between the two extension sections according to the patient's specific oral condition and treatment needs, thereby enabling the two support sections to expand to different degrees to meet different treatment requirements.

[0015] This dental expander features an inflatable component connected to the extension section. When the distance between the two extension sections is adjusted by the adjustment mechanism to expand the oral cavity, the air bladder can be inflated simultaneously, causing the air bladder to expand and press further against the oral cavity. This close contact not only improves the stability of the dental expander but also enhances the support force of the support section. At the same time, the design of the air bladder can reduce the pressure and discomfort on the oral tissues. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This embodiment provides an oral expander for dental use, such as... Figures 1-3As shown, the oral dilator includes two extensions 2 that move closer to or further away from each other, and a support 1 fixedly disposed at one end of the extensions 2 for supporting the oral cavity; the oral dilator also includes an adjustment mechanism 3 disposed at the end of the extensions 2 away from the support 1 for moving the two extensions 2, an airbag 11 fixedly disposed on the side of the support 1 near the oral cavity for pressing against the oral cavity, and an inflation assembly 4 connected to the extensions 2 for inflating or contracting the airbag 11; the inflation assembly 4 includes an air cylinder 41 disposed on the side of the two extensions 2 away from each other, a piston 42 that moves laterally in the air cylinder 41, a push rod 43 that passes through the side of the air cylinder 41 near the extensions 2 and is fixedly connected at both ends to the piston 42 and the extensions 2 respectively, and a hose 44 fixedly connected to the end of the air cylinder 41 away from the extensions 2 and communicating with the airbag 11, and the push rod 43 is slidably connected to the air cylinder 41.

[0027] In use, the doctor first uses the two support parts 1 to support the patient's oral cavity wall. Then, according to the treatment needs or the size of the patient's oral cavity, the doctor operates the adjustment mechanism 3 to move the two extension parts 2 away. Since the extension parts 2 are fixedly connected to the support parts 1, when the two extension parts 2 move away, the two support parts 1 will also move away accordingly, thereby achieving different degrees of oral cavity expansion. Since the push rod 43 is connected to the corresponding extension part 2, when the two extension parts 2 are moved away by the adjustment mechanism 3, the extension part 2 will synchronously drive the push rod 43 connected to it to push the piston 42 to move laterally towards the side of the hose 44 inside the air cylinder 41. At this time, as the piston 42 moves laterally, the air in the cylinder 41 is compressed and delivered to the airbag 11 through the hose 44, causing the airbag 11 to expand or contract. As the airbag 11 expands, it will further press against the oral cavity, thereby increasing the stability and support of the oral cavity dilator. Conversely, when the operating adjustment mechanism 3 moves the two extensions 2 closer, the two support parts 1 will move closer synchronously, thereby releasing the dilation of the oral cavity by the two support parts 1. At the same time, the push rod 43 will push the push rod 43 to move laterally away from the hose 44, so that the gas in the airbag 11 will be drawn back into the cylinder 41.

[0028] In order to facilitate the fit of the support part 1 to the oral cavity, the support part 1 has an arc-shaped or U-shaped structure; this shape design allows the support part 1 to fit well to the patient's oral cavity and provide stable support.

[0029] Specifically, a handhold 5 is fixedly installed on one side of each of the two air cylinders 41. The handhold 5 is located on the side of the two extensions 2 away from the support 1. When the doctor needs to use the oral dilator or operate the adjustment mechanism 3, he can hold the handhold 5 before using or operating it.

[0030] Furthermore, the adjustment mechanism 3 includes a bidirectional screw 31 that extends laterally through the two extensions 2 and is screwed to the two extensions 2. The two ends of the bidirectional screw 31 are rotatably connected to the handheld frame 5. The adjustment mechanism 3 also includes a rotating body 32 that is fixedly sleeved on the bidirectional screw 31 and located between the two extensions 2.

[0031] When it is necessary to operate the adjustment mechanism 3 to move the two extensions 2 closer or further apart, the doctor can hold the rotating body 32. Since the rotating body 32 is fixedly connected to the bidirectional screw 31 and the bidirectional screw 31 is rotatably connected to the handheld frame 5, the bidirectional screw 31 will also rotate synchronously when the rotating body 32 is rotated. Since the bidirectional screw 31 is screwed to the two extensions 2 and the two extensions 2 are connected to the push rod 43, and the push rod 43 is slidably connected to the air cylinder 41, the two extensions 2 can move stably closer or further apart on the bidirectional screw 31 when the bidirectional screw 31 is rotated.

[0032] In addition, to enhance the stability of holding the rotating body 32, the surface of the rotating body 32 is provided with anti-slip texture 321; the design of anti-slip texture 321 can increase the friction between the doctor's hand and the rotating body 32, effectively preventing the hand from slipping during rotation and improving the stability of operation.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
