Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an oral stent. Background Technology

[0002] During head and facial radiotherapy, patients need to keep their mouths open to allow for precise irradiation of specific areas. However, existing oral support structures or bite plates have several shortcomings. While products manufactured using 3D scanning and printing or bite plate fabrication can create supports that conform to the patient's oral shape, production costs are high, production cycles are long, and once completed, the mouth opening cannot be adjusted, making it difficult to adapt to varying opening requirements during actual treatment. Universal bite plates primarily protect the tongue and lips, offering insufficient protection for teeth and gums. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide an oral support.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an oral support, comprising:

[0005] First bracket, second bracket, and angle adjustment assembly;

[0006] The first bracket and the second bracket are arranged opposite to each other, and an operating cavity is formed between the first bracket and the second bracket. One end of the first bracket and the second bracket are connected by a rotating shaft, and the other end of the first bracket and the second bracket are adjustablely connected by the angle adjustment component.

[0007] The first bracket has a first dental seat on the side facing away from the operating cavity, and the second bracket has a second dental seat on the side facing away from the operating space.

[0008] Main working principle: When the oral support is not in use, the first and second supports are naturally connected by a pivot at one end, forming an initial angle between them, and the enclosed operating cavity is in a ready-to-open state. The first and second dental supports are respectively fixed to the side of the first and second supports facing away from the operating cavity, in a relative position, in preparation for subsequent tooth support.

[0009] When a patient needs to undergo procedures requiring opening the mouth, such as head and face radiotherapy, an oral support frame is placed inside the mouth. At this time, the patient's upper teeth contact the first dental arch on the first support frame, and the lower teeth contact the second dental arch on the second support frame. The first and second dental arches are designed according to the natural shape and arrangement of human teeth, providing a good fit and stable support, preventing tooth fatigue or displacement due to prolonged mouth opening during treatment.

[0010] The first and second supports are flexibly connected at their other ends via an angle adjustment component. This component allows for flexible adjustment of the angle between the first and second supports according to actual treatment needs, thereby changing the size of the operating cavity, i.e., adjusting the opening degree of the patient's mouth. Patients or medical personnel can adjust the opening degree by operating the angle adjustment component. After adjusting to a suitable opening degree, the patient maintains the position of the oral supports within the mouth, ensuring a stable operating cavity. At this time, doctors or other medical personnel can perform procedures such as head and face radiotherapy within the operating cavity. Due to the supporting role of the first and second supports, and the fixing effect of the first and second dental arches on the teeth, the patient's mouth maintains a stable opening, providing ample operating space for treatment and ensuring its accuracy and effectiveness.

[0011] After treatment, the patient can, either independently or with assistance, adjust the angle between the first and second supports using the angle adjustment component to restore the angle to its initial state for easy removal. Then, the oral support is gently removed from the mouth, completing the entire procedure. Throughout the process, the first and second supports, through the cooperation of the pivot and angle adjustment component, enable adjustable oral opening; the first and second dental supports provide stable support for the teeth, ensuring patient comfort and safety during treatment.

[0012] Preferably, the angle adjustment component includes a locking hole and a locking block;

[0013] The bracket has multiple slots, which are symmetrically arranged on both sides of the first bracket. The locking blocks are arranged on both sides of the second bracket, and the locking blocks engage with the slots respectively.

[0014] Alternatively, multiple card holes are provided, and the multiple card holes are symmetrically arranged on both sides of the second bracket. The card blocks are respectively arranged on both sides of the first bracket, and the card blocks are engaged with the card holes respectively.

[0015] Preferably, the angle adjustment component further includes an unlocking block.

[0016] When the locking block is located on both sides of the second bracket, the unlocking block is located on both sides of the second bracket, and the unlocking block extends outward toward the outside of the oral cavity;

[0017] When the locking block is located on both sides of the first bracket, the unlocking block is located on both sides of the first bracket, and the unlocking block extends outward toward the outside of the oral cavity.

[0018] Preferably, one side of the card hole is provided with a straight card edge, and the corresponding position of the card block is provided with a straight card platform, the straight card edge and the straight card platform cooperating with each other.

[0019] Preferably, the bottom of the second support is provided with a tongue depressor that extends toward the inside of the oral cavity.

[0020] Preferably, the first bracket has a first disassembly hole on the side facing away from the operating cavity, and the bottom of the first tooth seat has a first protrusion, and the first disassembly hole is detachably connected to the first protrusion;

[0021] The second bracket has a second disassembly hole on the side facing away from the operating cavity, and the bottom of the second tooth seat has a second protrusion. The second disassembly hole and the second protrusion are detachably connected.

[0022] Preferably, both the first and second dental arches are made of silicone material.

[0023] Preferably, the second bracket is provided with collars on both sides, and the collars on both sides are respectively connected to the two ends of a rope.

[0024] Preferably, the surfaces of the first bracket and the second bracket are provided with a smooth coating.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention, through an angle adjustment component, can flexibly and precisely adjust the angle between the first and second supports, thereby changing the size of the operating cavity to meet the personalized needs of opening degree in various treatment scenarios and ensure the smooth progress of treatment operations. A suitable opening degree provides medical personnel with a clearer and more convenient treatment field of vision and space, helping to improve treatment accuracy, reduce errors caused by operational inconvenience, and enhance treatment outcomes.

[0027] Meanwhile, when patients keep their mouths open for extended periods, their teeth are prone to fatigue and even displacement. The first dental arch, located on the side of the first support facing away from the operating cavity, and the second dental arch, located on the side of the second support facing away from the operating space, can closely conform to the patient's teeth, providing stable support and effectively preventing tooth fatigue or displacement due to prolonged opening during treatment. This ensures the normal physiological state of the teeth and the stability of the oral cavity structure. Attached Figure Description

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Example 1

[0036] This embodiment discloses an oral support, such as Figures 1-3As shown, the device includes a first support 1, a second support 2, and an angle adjustment component 3. When not in use, the first support 1 and the second support 2 are naturally connected by a pivot at one end, forming an initial angle between them, and the enclosed operating cavity 4 is in a ready-to-open state. The first dental support 10 and the second dental support 20 are respectively fixed to the side of the first support 1 and the second support 2 facing away from the operating cavity 4, in a relative position, preparing for subsequent tooth support. The leading edge of the first support 1 and the second support 2 is higher than the trailing edge, which can prevent the support from slipping, falling into and getting stuck in the oral cavity.

[0037] When a patient needs to undergo procedures requiring opening the mouth, such as head and face radiotherapy, an oral support is placed inside the mouth. At this time, the patient's upper teeth contact the first dental seat 10 on the first support 1, and the lower teeth contact the second dental seat 20 on the second support 2. The first dental seat 10 and the second dental seat 20 are designed according to the natural shape and arrangement of human teeth, providing a good fit and stable support, preventing tooth fatigue or displacement due to prolonged mouth opening during treatment.

[0038] The other ends of the first support 1 and the second support 2 are flexibly connected via an angle adjustment component 3. The angle adjustment component 3 can flexibly adjust the angle between the first support 1 and the second support 2 according to actual treatment needs, thereby changing the size of the operating cavity 4, i.e., adjusting the opening degree of the patient's oral cavity. Patients or medical personnel can adjust the opening degree by operating the angle adjustment component 3. After adjusting to a suitable opening degree, the patient maintains the position of the oral support within the oral cavity, ensuring the operating cavity 4 is stable. At this time, doctors or other medical personnel can perform procedures such as head and face radiotherapy within the operating cavity 4. Due to the supporting effect of the first support 1 and the second support 2, and the fixing effect of the first dental arch 10 and the second dental arch 20 on the teeth, the patient's oral cavity can maintain a stable opening state, providing a good operating space for treatment and ensuring the accuracy and effectiveness of the treatment.

[0039] After treatment, the patient can, either independently or with assistance, adjust the angle between the first support 1 and the second support 2 using the angle adjustment component 3 to restore the angle to its initial state for easy removal. Then, the oral support is gently removed from the mouth, completing the entire process. Throughout the procedure, the first support 1 and the second support 2, through the cooperation of the pivot and the angle adjustment component 3, achieve adjustable oral opening; the first dental seat 10 and the second dental seat 20 provide stable support for the teeth, ensuring patient comfort and safety during treatment.

[0040] In some optional embodiments, the angle adjustment component 3 employs a structure of locking holes 30 and locking blocks 31. Multiple locking holes 30 are symmetrically arranged on both sides of the first support 1, and locking blocks 31 that mate with the locking holes 30 are arranged on both sides of the second support 2; or vice versa. The number of locking holes 30 and locking blocks 31 is set according to actual needs, such as two locking holes 30 on each side, arranged at a certain distance. When it is necessary to adjust the opening degree, the locking block 31 is pulled out from the current locking hole 30, and a new locking hole 30 of appropriate size is selected and inserted into the locking block 31. For example, in the early stages of treatment, when the patient's mouth can open easily, the locking hole 30 corresponding to the larger angle is selected; as the treatment progresses and the patient's mouth becomes fatigued, the locking hole 30 corresponding to the smaller angle is selected, achieving flexible adjustment of the opening degree.

[0041] In some optional embodiments, when the locking block 31 is located on both sides of the second support 2, the unlocking block 32 is also located on both sides of the second support 2 and extends outwards from the oral cavity; when the locking block 31 is located on both sides of the first support 1, the unlocking block 32 is located on both sides of the first support 1 and extends outwards from the oral cavity. The unlocking block 32 can be made of the same material as the support and is shaped like a block for easy finger operation. When the angle needs to be adjusted, the patient or medical staff presses the unlocking block 32 with their fingers to loosen the engagement between the locking block 31 and the locking hole 30, and then easily pulls the locking block 31 out of the locking hole 30, selects a new locking hole 30 to insert the locking block 31, and completes the angle adjustment. The design of the unlocking block 32 increases the ease of operation and makes angle adjustment easier.

[0042] In some optional embodiments, a straight locking edge 33 is provided on one side of the locking hole 30, and a straight locking platform 34 is provided at the corresponding position of the locking block 31. The straight locking edge 33 and the straight locking platform 34 can be made of the same medical material as the bracket and integrally formed by molding. When the locking block 31 is inserted into the locking hole 30, the straight locking platform 34 and the straight locking edge 33 cooperate with each other to form a stable locking structure. This design increases the contact area and friction between the locking block 31 and the locking hole 30, improves the stability and reliability of the angle adjustment component 3, and prevents the locking block 31 from accidentally falling off during treatment and affecting the treatment operation.

[0043] In some optional embodiments, a tongue depressor 21 is provided at the bottom of the second support 2, extending towards the inside of the oral cavity. The tongue depressor 21 can be made of medical-grade material, and is flat and plate-shaped, with its width and length designed according to actual needs. When the oral support is placed in the oral cavity, the tongue depressor 21 naturally rests above the tongue, pressing the tongue towards the bottom of the oral cavity to prevent the tongue from moving freely during treatment, thus affecting the treatment field of vision and operation. At the same time, the design of the tongue depressor 21 also makes the patient feel more comfortable and reduces tongue discomfort.

[0044] In some optional embodiments, the tongue depressor 21 is provided with an interface 22, and the base plate of the second support 2 is provided with an insertion rod 23 facing the inside of the oral cavity. The interface 22 and the insertion rod 23 are interlocked. The interface 22 and the insertion rod 23 can be made of the same medical material as the support and are integrally molded. When it is necessary to install or remove the tongue depressor 21, the interface 22 is aligned with the insertion rod 23, and it is inserted or pulled out forcefully. This detachable design facilitates the cleaning, disinfection and replacement of the tongue depressor 21, and also allows for the selection of whether to install the tongue depressor 21 according to the patient's oral condition, improving the versatility of the oral support.

[0045] In some optional embodiments, the first support 1 has a first disassembly hole 12 on the side facing away from the operating cavity 4, and the first dental base 10 has a first protrusion 11 at its bottom. The first disassembly hole 12 and the first protrusion 11 are detachably connected. The second support 2 has a second disassembly hole 24 on the side facing away from the operating cavity 4, and the second dental base 20 has a second protrusion 25 at its bottom. The second disassembly hole 24 and the second protrusion 25 are detachably connected. When the dental base needs to be replaced or cleaned, the protrusion at the bottom of the dental base can be pulled out from the disassembly hole on the support to remove the dental base. During installation, the protrusion is aligned with the disassembly hole and inserted forcefully. This detachable design facilitates the cleaning, disinfection, and replacement of the dental base, and also allows for the selection of dental bases of different shapes and sizes according to the patient's dental condition, improving the applicability of the oral support system.

[0046] In some optional embodiments, both the first dental arch 10 and the second dental arch 20 are made of silicone. Silicone is soft, elastic, non-toxic, and odorless, and can be molded using injection molding. When a patient bites down on the dental arch, the silicone arch conforms better to the shape of the teeth, providing more comfortable support and reducing discomfort. At the same time, the softness of the silicone material prevents damage to the teeth caused by an overly hard arch, improving the safety and comfort of the oral support system.

[0047] In some optional embodiments, the second support 2 has loops 26 on both sides, each loop 26 being connected to one end of a rope. The rope can be made of soft medical cotton thread or nylon thread. When the patient wears the oral support, the rope is hung on the ears to secure the oral support inside the mouth, preventing it from falling off during treatment. This design increases the stability of the oral support, and the rope can also be adjusted according to the size of the patient's head, improving wearing comfort.

[0048] In some optional embodiments, the surfaces of the first stent 1 and the second stent 2 are provided with a smooth coating. The smooth coating may be a medical-grade coating, uniformly applied to the stent surface via a spraying process. The smooth coating reduces friction between the stent and the oral mucosa, lowering the risk of damage to the patient's oral mucosa. Simultaneously, the smooth surface facilitates cleaning and disinfection, preventing bacterial growth and improving the hygiene and safety of the oral stent.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
