Description

Technical Field

[0001] This invention relates to the field of oral medical devices, specifically an auxiliary sleeve for the treatment of dental pulp diseases. Background Technology

[0002] In the clinical treatment of dental endodontic diseases, precise manipulation of the affected tooth is essential, while maintaining a sterile environment in the surgical area is crucial to prevent cross-contamination between the affected tooth and surrounding teeth and oral tissues. Therefore, auxiliary devices for tooth concealment, positioning, and mouth opening support are critical equipment in the treatment process. Currently, commonly used clinical auxiliary tools are mostly single-function tooth concealers or mouth openers, lacking integrated design and failing to simultaneously meet multiple treatment needs such as positioning, isolation, and support, causing considerable inconvenience for medical staff and patients.

[0003] In existing technologies, most tooth-covering devices are fixed structures, which cannot flexibly adjust the area of ​​the exposed tooth according to the position of the affected tooth, and the isolation and sealing are poor. The rinsing fluid and saliva generated during treatment are easy to spread, which can not only contaminate the surgical field, but also may flow back into the throat and cause discomfort to the patient. Mouth-opening support devices are mostly rigid structures with fixed and non-adjustable support force, which cannot adapt to patients with different mouth strengths. Moreover, patients have difficulty relaxing properly when keeping their mouths open for a long time, which can easily cause facial muscle soreness and fatigue, and may even cause pressure damage to the muscles and joints around the mouth.

[0004] Furthermore, existing auxiliary tools suffer from poor positioning stability and are prone to displacement during treatment procedures or slight patient movements, affecting treatment accuracy. They also lack a convenient fluid collection structure, making it impossible to promptly handle fluids generated during treatment, further reducing treatment safety and comfort. Therefore, developing an integrated oral cavity and endodontic treatment auxiliary sleeve that can achieve precise positioning, tight isolation, stable support, and strong adaptability, while also collecting treatment fluids, has become an urgent technical problem to be solved in current clinical practice. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an auxiliary sleeve for the treatment of dental caries and pulpitis, which solves the problems of existing auxiliary tools for the treatment of dental caries and pulpitis, such as limited functionality, poor isolation and sealing, non-adjustable support force, unstable positioning, and lack of liquid collection function.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for the treatment of dental caries and pulpitis, comprising a lower conformal tooth-masking component and an upper conformal tooth-masking bracket. The lower conformal tooth-masking component includes two parallel arc-shaped positioning plates. A positioning opening mechanism is movably provided on the surface of the lower conformal tooth-masking component. The positioning opening mechanism includes a blocking plate. A tooth-leaking groove is formed in the middle of the blocking plate. Soft rubber sealing gaskets are fixedly installed on both sides of the bottom end of the blocking plate near the tooth-leaking groove. Both tail ends of the lower conformal tooth-masking component are... A dental membrane control assembly is provided. The ends of the lower conformal tooth-masking assembly and the upper conformal tooth-masking frame are connected by a support assembly. The support assembly includes a dovetail fixing block. A crossbeam is fixedly installed on both the upper and lower sides of the inner end of the dovetail fixing block. A rotating frame is movably installed at the end of each crossbeam. A spring plate is fixedly installed on both sides of the inner side of each crossbeam, and the end of each spring plate extends into the interior of the corresponding rotating frame. A pressure roller is fixedly installed on the inner wall of each rotating frame, and the inner end of each pressure roller abuts against the surface of the corresponding spring plate.

[0007] Preferably, the tail ends of the arc-shaped positioning pieces are connected and fixed by a connecting bridge. Several limiting grooves are provided on the outer ends of the arc-shaped positioning pieces, and a liquid storage tank is fixedly installed on the inner end of the inner side of the arc-shaped positioning pieces. The inside of the liquid storage tank is filled with absorbent cotton.

[0008] Preferably, side baffles are fixedly installed on both sides of the bottom end of the tooth groove, and the bottom of each side baffle is provided with a movable groove, and the interior of each movable groove is movably arranged on the upper part of the arc-shaped positioning piece on the corresponding side. Several limiting protrusions are fixedly installed on the inner side wall of each movable groove.

[0009] Preferably, the overlay control assembly includes a storage compartment, and a movable shaft is movably installed inside the storage compartment. An elastic overlay is wound around the outer diameter of the middle part of the movable shaft. An opening groove is opened on the outer surface of the storage compartment. The end of the elastic overlay passes through the opening groove and is fixedly installed on the outer end of the soft rubber sealing pad on the corresponding side. Coil springs are fixedly installed on the outer diameters of both sides of the movable shaft.

[0010] Preferably, the ends of the upper rotating frame are fixedly installed on both sides of the rear end of the upper conforming tooth-masking frame, and the ends of the lower rotating frame are fixedly installed on both sides of the rear end of the lower conforming tooth-masking assembly.

[0011] Preferably, each of the dovetail fixing blocks has a cavity inside, and a drive shaft is movably installed in the middle of the inner side wall of each crossbar. The inner end of each drive shaft extends into the cavity and is fixedly installed with a worm gear.

[0012] Preferably, each of the crossbeams has a support platform movably installed inside, and both sides of the support platform abut against the surface of the corresponding spring sheet. Each of the outer ends of the drive shaft has a lead screw fixedly installed, and the outer diameter of the lead screw is threaded to the middle of the corresponding support platform.

[0013] Preferably, an internal hexagonal adjusting nut is movably installed on one side of each of the dovetail fixing blocks, and the inner end of each internal hexagonal adjusting nut extends into the cavity and is fixedly installed with a worm gear. The inner end of each worm wheel is engaged with the outer wall of the corresponding side of the worm gear.

[0014] This invention provides an auxiliary sleeve for the treatment of oral cavity and pulp diseases. It has the following beneficial effects: 1. This invention uses a movable shielding plate in conjunction with a soft rubber sealing pad to precisely align the exposed tooth socket with the affected tooth. The locking mechanism, consisting of a limiting protrusion and a limiting groove, secures the tooth, while the soft rubber sealing pad tightly adheres to both sides of the affected tooth. Simultaneously, the movement of the shielding plate unfolds the elastic overlay membrane, and the spring action keeps the membrane taut and in contact with the remaining teeth, completely isolating the affected tooth from surrounding teeth. This effectively prevents cross-contamination of bacteria during treatment, creating a clean and sterile surgical area for endodontic treatment and improving treatment safety and success rate.

[0015] 2. The support assembly of this invention, through the cooperation of spring plates, pressure rollers, and a rotating frame, provides stable support when the patient opens their mouth, while allowing the patient to perform moderate mouth opening and closing movements or reduce the range of mouth opening to relax. When the rotating frame bends, the pressure roller slides on the surface of the spring plate, dynamically compensating for changes in elasticity during the bending process of the spring plate, so that the support force remains stable at all times. This avoids facial soreness and muscle fatigue caused by prolonged mouth opening, while maintaining the fixed position of the device, thus balancing support stability and patient comfort, and improving the patient's treatment experience.

[0016] 3. The tooth socket of the shielding plate of the present invention can be precisely aligned with the affected tooth, providing medical staff with a clear operating field and sufficient operating space, avoiding obstruction of the treatment operation by surrounding teeth; at the same time, the combination of the liquid storage tank and the absorbent cotton can collect the liquid generated during the operation (such as irrigation fluid, saliva, etc.) in time and absorb it quickly, preventing the liquid from flowing back into the patient's throat and causing discomfort, and also avoiding the liquid from affecting the surgical field, reducing operation interference, improving treatment efficiency and the convenience of operation for medical staff.

[0017] 4. The device of this invention features an adjustment structure consisting of an internal hexagonal adjusting nut, a worm gear, a worm wheel, a lead screw, and a support platform. Medical personnel can rotate the adjusting nut using an internal hexagonal wrench, causing the worm gear, worm wheel, and drive shaft to rotate, thereby driving the support platform to move back and forth, changing the support point when the spring plate bends, and adjusting the elastic force generated by the spring plate. This design can be adaptively adjusted according to the differences in mouth strength and mouth opening range among different patients, making it suitable for various groups of people and expanding the applicability of the device.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Please see the appendix Figure 1 - Appendix Figure 5 This invention provides an auxiliary sleeve for the treatment of oral dental pulp diseases, such as... Figure 1As shown, the device includes a lower conformal tooth-masking assembly 1 and an upper conformal tooth-masking bracket 2. The lower conformal tooth-masking assembly 1 includes two parallel arc-shaped positioning plates 101. A positioning opening mechanism 3 is movably disposed on the surface of the lower conformal tooth-masking assembly 1. The positioning opening mechanism 3 includes a blocking plate 301. A tooth-leaking groove 302 is opened in the middle of the blocking plate 301. Soft rubber sealing gaskets 306 are fixedly installed on both sides of the bottom end of the blocking plate 301 near the tooth-leaking groove 302. Overlay membrane control components 4 are provided on both tail ends of the lower conformal tooth-masking assembly 1. The lower conformal tooth-masking assembly 1 and the upper conformal tooth-masking bracket 2... The ends of the tooth-covering bracket 2 are all connected by a support assembly 5. The support assembly 5 includes a dovetail fixing block 501. A crossbeam 502 is fixedly installed on both the upper and lower sides of the inner end of the dovetail fixing block 501. A rotating frame 503 is movably installed at the end of the crossbeam 502. A spring plate 504 is fixedly installed on both sides of the inner side of the crossbeam 502, and the end of the spring plate 504 extends into the interior of the corresponding rotating frame 503. A pressure roller 505 is fixedly installed on the inner wall of the rotating frame 503, and the inner end of the pressure roller 505 abuts against the surface of the corresponding spring plate 504. The lower conformal tooth-masking component 1 is mainly used to adhere to and fix the patient's lower teeth, while the upper conformal tooth-masking bracket 2 is used to adhere to and fix the patient's upper teeth. The two work together to achieve overall positioning of the device in the oral cavity, providing a stable foundation for subsequent treatment operations. The two parallel arc-shaped positioning plates 101 are designed to fit the outer contour of the lower teeth, ensuring a close fit to the tooth surface and preventing displacement of the device during use. They also provide a stable mounting and moving platform for the positioning and opening mechanism 3. The core function of the positioning and opening mechanism 3 is to accurately locate the affected tooth and achieve initial isolation between the affected tooth and surrounding teeth. The masking plate 301 can move flexibly along the surface of the lower conformal tooth-masking component 1, allowing medical staff to adjust the alignment direction of the exposed tooth socket 302 according to the position of the affected tooth. The exposed tooth socket 302 can accurately expose the affected tooth, providing medical staff with a clear operating field and sufficient operating space, and preventing surrounding teeth from obstructing the treatment operation. The soft rubber sealing pad 306 is made of soft and elastic medical-grade soft rubber material. It will not damage the tooth surface when applied to the tooth, and it can closely fit the teeth on both sides of the affected tooth, enhancing the seal around the exposed tooth socket 302 and preventing the spread of liquids or bacteria generated during treatment. The overlay control component 4 works with the masking plate 301 to achieve complete isolation between the affected tooth and surrounding teeth, ensuring a sterile environment in the surgical area. The support component 5 connects the lower conformal masking component 1 and the upper conformal masking frame 2, supporting the patient to maintain an open mouth while allowing for moderate mouth opening and closing movements, relieving the soreness and fatigue caused by prolonged mouth opening.The dovetail fixing block 501, as the core fixing component of the support assembly 5, can stably install the upper and lower crossbeams 502. The crossbeams 502 provide a mounting carrier for components such as the rotating frame 503 and the spring plate 504. The rotating frame 503 can rotate flexibly relative to the crossbeams 502 to adapt to the angle changes when the patient's mouth opens and closes. The spring plate 504 has good elastic deformation capability. The part of it extending into the interior of the rotating frame 503 can deform accordingly as the rotating frame 503 bends, thereby generating a reverse elastic force to provide support for the rotating frame 503. The pressure roller 505 abuts against the surface of the spring plate 504. When the rotating frame 503 bends and drives the pressure roller 505 to move, the pressure roller 505 can slide on the surface of the spring plate 504, dynamically compensating for the change of elastic force during the bending process of the spring plate 504, ensuring that the elastic force generated by the spring plate 504 is always stable, thereby ensuring the stability of the support force of the support assembly 5 on the lower conformal tooth-masking assembly 1 and the upper conformal tooth-masking frame 2, maintaining the fixed position of the device and improving the patient's comfort.

[0022] In this embodiment, the tails of the arc-shaped positioning pieces 101 are connected and fixed together by a connecting bridge 102. Several limiting grooves 103 are provided on the outer ends of each arc-shaped positioning piece 101, and a liquid storage tank 104 is fixedly installed on the inner end of each inner arc-shaped positioning piece 101. The liquid storage tank 104 is filled with absorbent cotton. The connecting bridge 102 is made of the same medical-grade rigid material as the arc-shaped positioning pieces 101, and its two ends are fixedly connected to the tails of the two arc-shaped positioning pieces 101 respectively. This securely connects the two arc-shaped positioning pieces 101 into a single unit, enhancing the structural stability of the lower conformal tooth-masking assembly 1, preventing relative displacement of the two arc-shaped positioning pieces 101 during use, and ensuring the device's fixation effect on the lower teeth. The limiting grooves 103 are evenly distributed on the outer end of the arc-shaped positioning piece 101, cooperating with the limiting protrusions 305 in the positioning opening mechanism 3. When the medical staff adjusts the position of the shielding piece 301 and aligns the tooth socket 302 with the affected tooth, pressing down on the shielding piece 301 will cause the limiting protrusions 305 to engage in the corresponding limiting grooves 103, achieving precise fixation of the shielding piece 301 and preventing it from moving during treatment. This ensures that the tooth socket 302 is always aligned with the affected tooth, guaranteeing the smooth progress of the treatment. The liquid reservoir 104 on the inner end of the inner arc-shaped positioning piece 101 is designed to fit the contour of the patient's oral cavity, accurately collecting various liquids generated during treatment, including rinsing fluid, saliva, and tissue fluid. This prevents these liquids from flowing back into the patient's throat, causing choking, nausea, or other discomfort, and also prevents liquid from contaminating the surgical area and affecting the treatment field of vision. The absorbent cotton filling the inside of the liquid reservoir 104 has good water absorption, which can quickly absorb the liquid collected in the liquid reservoir 104, keep the liquid reservoir 104 dry and clean, reduce liquid residue in the oral cavity, further improve the patient's comfort, and at the same time avoid bacterial growth caused by prolonged liquid retention, ensuring the sterility of the treatment process.

[0023] Furthermore, side baffles 303 are fixedly installed on both sides of the bottom end of the tooth socket 302. Each side baffle 303 has a movable groove 304 at its bottom, and the interior of each movable groove 304 is movably positioned on the upper part of the corresponding side arc-shaped positioning piece 101. Several limiting protrusions 305 are fixedly installed on the inner wall of each movable groove 304. The side baffles 303 and the shielding piece 301 are integrally formed. Their main function is to shield both sides of the tooth socket 302, further isolating the affected tooth from surrounding teeth and preventing the spread of liquids, debris, or bacteria generated during treatment from both sides of the tooth socket 302. They also guide the movement of the shielding piece 301, ensuring that it moves smoothly along the surface of the arc-shaped positioning piece 101 and avoiding deviation. The movable groove 304 at the bottom of the side baffle 303 is adapted to the upper part of the arc-shaped positioning piece 101. The movable groove 304 is fitted onto the upper part of the arc-shaped positioning piece 101, so that the shielding piece 301 can move flexibly along the length of the arc-shaped positioning piece 101 through the movable groove 304. This makes it convenient for medical staff to adjust the alignment position of the tooth gap 302 according to the specific position of the affected tooth, adapting to the tooth distribution of different patients and the treatment needs of affected teeth in different positions. The limiting protrusion 305 on the inner wall of the movable groove 304 is made of elastic material. Its position corresponds to the limiting groove 103 on the outer end of the arc-shaped positioning piece 101. When the shielding piece 301 is adjusted into place, pressing down on the shielding piece 301 will cause the limiting protrusion 305 to engage with the corresponding limiting groove 103 under pressure. Through the engaging action of the limiting protrusion 305 and the limiting groove 103, the shielding piece 301 is fixed, ensuring that the shielding piece 301 will not move during treatment. At the same time, this engaging structure also makes it easy for medical staff to adjust the position of the shielding piece 301 at any time according to treatment needs, making the operation convenient and efficient.

[0024] Furthermore, the overlay control assembly 4 includes a storage compartment 401. A movable shaft 402 is movably mounted inside the storage compartment 401. An elastic overlay 403 is wound around the outer diameter of the middle part of each movable shaft 402. An opening groove 404 is formed on the outer surface of each storage compartment 401. The end of each elastic overlay 403 passes through the opening groove 404 and is fixedly installed on the outer end of the corresponding soft rubber sealing gasket 306. Coil springs 405 are fixedly installed on both outer diameters of the movable shaft 402. The storage compartment 401 is fixedly installed on both sides of the lower conformal overlay assembly 1, mainly for storing the elastic overlay 403, preventing the elastic overlay 403 from becoming entangled or contaminated when not in use, and providing a stable mounting carrier for components such as the movable shaft 402 and coil springs 405. The movable shaft 402 can rotate flexibly inside the storage compartment 401. Its main function is to wind and release the elastic dental membrane 403. The elastic dental membrane 403 is made of a medical film material with good elasticity and sealing properties, which can closely fit the tooth surface, achieve complete isolation between the affected tooth and surrounding teeth, and establish a sterile surgical area. The opening slot 404 is formed on the outer surface of the storage compartment 401. Its size is adapted to the width of the elastic dental membrane 403, providing a channel for the entry and exit of the elastic dental membrane 403, ensuring that the elastic dental membrane 403 can be smoothly pulled out or retracted from the storage compartment 401. The end of the elastic overlay 403 is fixedly connected to the outer end of the soft rubber sealing pad 306. When the medical staff moves the shield 301, the shield 301 will drive the soft rubber sealing pad 306 to move synchronously, thereby pulling the elastic overlay 403 out of the storage compartment 401 through the opening slot 404. As the shield 301 is pressed down, the elastic overlay 403 will gradually unfold and fit tightly against the surface of the remaining teeth except the affected tooth, achieving complete isolation. The coil springs 405 on both sides of the movable shaft 402 have good elastic reset capability. When the elastic overlay membrane 403 is pulled out, the coil spring 405 will deform and generate a reverse tension, so that the elastic overlay membrane 403 always remains taut, ensuring that the elastic overlay membrane 403 can closely fit the tooth surface and improve the isolation effect. When the treatment is completed and the medical staff moves the shielding plate 301 to reset, the coil spring 405 will drive the movable shaft 402 to reverse, and rewrap the elastic overlay membrane 403 on the movable shaft 402, realizing the automatic storage of the elastic overlay membrane 403, which facilitates the subsequent cleaning and storage of the device.

[0025] Furthermore, the ends of the upper rotating frame 503 are fixedly installed on both sides of the rear end of the upper conforming tooth-masking frame 2, and the ends of the lower rotating frame 503 are fixedly installed on both sides of the rear end of the lower conforming tooth-masking assembly 1. The upper rotating frame 503 is fixedly connected to both sides of the rear end of the upper conforming tooth-masking frame 2, and the lower rotating frame 503 is fixedly connected to both sides of the rear end of the lower conforming tooth-masking assembly 1. This connection method ensures that the rotating frame 503 moves synchronously with the corresponding tooth-masking assembly or tooth-masking frame. When the patient adjusts the size of their mouth opening, the upper conforming tooth-masking frame 2 and the lower conforming tooth-masking assembly 1 will move with the opening and closing of the mouth, thereby causing the corresponding rotating frame 503 to bend and rotate relative to the cross frame 502. The upper and lower rotating frames 503 are symmetrically arranged, which can provide stable support for the upper conforming tooth-masking frame 2 and the lower conforming tooth-masking assembly 1 respectively, ensuring the balance of the device in the patient's oral cavity and avoiding unilateral tilting. Meanwhile, the installation method of the rotating frame 503 also allows the support component 5 to flexibly adapt to the changes in the opening and closing angle of the patient's mouth. It can support the patient to maintain a certain mouth opening range, which is convenient for medical staff to perform treatment operations, and also allow the patient to perform moderate mouth relaxation activities to relieve muscle fatigue and soreness caused by long-term mouth opening, thus taking into account both treatment convenience and patient comfort.

[0026] Furthermore, each of the dovetail fixing blocks 501 has an internal cavity 506, and a drive shaft 507 is movably mounted in the middle of the inner wall of the crossbeam 502. The inner end of the drive shaft 507 extends into the cavity 506 and is fixedly mounted with a worm gear 510. The cavity 506 inside the dovetail fixing block 501 is mainly used to accommodate adjusting components such as the worm gear 510 and worm 512, providing installation and movement space for these components. It also protects these components from corrosion by saliva and treatment fluids in the oral cavity, extending the service life of the device. The drive shaft 507 in the middle of the inner wall of the crossbeam 502 can rotate flexibly inside the crossbeam 502. Its main function is to transmit power, transmitting the rotation of the worm gear 510 to the lead screw 508, thereby driving the support platform 509 to move. The inner end of the drive shaft 507 extends into the cavity 506 and is fixedly connected to the worm gear 510, ensuring that the worm gear 510 can drive the drive shaft 507 to rotate synchronously when it rotates. The transmission process is stable and reliable, and there will be no interruption of power transmission or slippage. As the core component of the transmission structure, the worm gear 510 meshes with the worm 512, converting the rotational motion of the worm 512 into its own rotational motion, thereby driving the drive shaft 507 to rotate and providing power for the displacement of the support platform 509, thus realizing the adjustment of the support force of the device.

[0027] Furthermore, each side of the crossbeam 502 has a movably mounted support platform 509, with both sides of the support platform 509 abutting against the surface of the corresponding side spring plate 504. A lead screw 508 is fixedly mounted on the outer end of each drive shaft 507, and the outer diameter of the lead screw 508 is threaded to the middle of the corresponding side support platform 509. The support platform 509 inside the crossbeam 502 can move back and forth along the length of the crossbeam 502. Its main function is to change the support point of the spring plate 504 when it bends, thereby adjusting the magnitude of the elastic force generated by the spring plate 504. The two sides of the support platform 509 abut against the surface of the corresponding side spring plate 504. When the support platform 509 moves back and forth, it pushes the spring plate 504 to undergo slight deformation, changing the force point of the spring plate 504, causing a corresponding change in the elastic force generated by the spring plate 504 when it bends. This allows for adjustment of the support force of the support component 5, adapting to the mouth strength needs of different patients. The lead screw 508 at the outer end of the drive shaft 507 is threadedly connected to the middle of the support platform 509. When the drive shaft 507 rotates, it will drive the lead screw 508 to rotate synchronously. Due to the threaded engagement between the lead screw 508 and the support platform 509, the rotational motion of the lead screw 508 will be converted into the linear motion of the support platform 509. This transmission method is precise and stable, and can realize the fine adjustment of the position of the support platform 509, ensuring that the adjustment of the support force is precise and controllable, and further improving the applicability of the device.

[0028] Furthermore, an internal hexagonal adjusting nut 511 is movably installed on one side of the dovetail fixing block 501. The inner end of the internal hexagonal adjusting nut 511 extends into the cavity 506 and is fixedly installed with a worm gear 512. The inner end of the worm wheel 510 is engaged with the outer wall of the corresponding side worm gear 512. The internal hexagonal adjusting nut 511 is installed on one side of the dovetail fixing block 501, which facilitates the use of an internal hexagonal wrench for rotation by medical personnel. The operation is convenient and does not slip, allowing for precise control of the adjustment range. The inner end of the internal hexagonal adjusting nut 511 extends into the cavity 506 and is fixedly connected with the worm gear 512. When medical personnel rotate the internal hexagonal adjusting nut 511, it will drive the worm gear 512 to rotate synchronously. The worm gear 512 and the worm wheel 510 mesh with each other. The rotation of the worm gear 512 will drive the worm wheel 510 to rotate, which in turn drives the support platform 509 to move back and forth through the transmission shaft 507 and the lead screw 508, thereby adjusting the support force. This adjustable structure is rationally designed and provides stable transmission. Medical staff can precisely adjust the position of the support platform 509 by rotating the internal hexagonal adjusting nut 511, according to the differences in mouth strength and opening range among different patients. This allows them to change the support point and elasticity of the spring plate 504, making the device adaptable to the needs of different users and expanding its applicability. Simultaneously, the design of the internal hexagonal adjusting nut 511 prevents accidental operation by non-medical personnel, ensuring the safety and precision of the device's adjustment. Before placing the device in the patient's mouth, medical staff can adjust the support force in advance according to the patient's specific situation. If the patient experiences discomfort after placement, fine adjustments can be made at any time, further improving patient comfort and treatment experience. Furthermore, the meshing structure of the worm gear 512 and worm wheel 510 has a self-locking function. After adjustment, there will be no relative rotation between the worm gear 512 and worm wheel 510, ensuring the stability of the support platform 509's position. This, in turn, ensures the stability of the support force of the support component 5, preventing device displacement due to changes in support force during treatment and guaranteeing the smooth progress of the treatment procedure.

[0029] Working principle: During use, the patient opens their mouth and inserts the device into their mouth. The lower conformal masking component 1 secures the lower teeth, and the upper conformal masking bracket 2 secures the upper teeth. Then, the medical staff moves the masking plate 301, aligning the exposed tooth socket 302 with the affected tooth, and presses down on the masking plate 301, causing the limiting protrusion 305 to engage with the limiting groove 103, thus securing the masking plate 301. After pressing down, the soft rubber sealing pad 306 conforms to the teeth on both sides of the affected tooth. Simultaneously, as the masking plate 301 moves, it moves the elastic overlay membranes 403 on both sides. The coil spring 405 keeps the elastic overlay membranes 403 taut. As the masking plate 301 descends, the elastic overlay membranes... The dental membrane 403 will also tightly adhere to the other teeth, thus maintaining a tight isolation between the affected tooth and surrounding teeth, establishing a sterile surgical area. Medical staff can then begin the surgical procedure on the affected tooth. During the procedure, prolonged mouth opening may cause soreness and discomfort. At this time, the patient can relax by opening and closing their mouth or reducing the range of mouth opening. When the patient adjusts the size of their mouth opening, it will cause the lower conformal masking component 1 and the upper conformal masking frame 2 to move accordingly. At this time, the two components will cause the rotating frame 503 to bend. The bent rotating frame 503 will press the spring sheet 504 through the pressure roller 505, utilizing the elasticity generated by the bent spring sheet 504... The force acts in the opposite direction to support the two tooth-blocking components, keeping the patient's mouth open. When the pressure roller 505 bends the spring sheet 504, it slides relative to the surface of the spring sheet 504, causing the lever arm of the bent spring sheet 504 to change accordingly. This compensates for the changing elastic force as the degree of bending of the spring sheet 504 changes, ensuring that the elastic force generated by the spring sheet 504 remains stable. This, in turn, keeps the supporting force of the support component 5 on the two tooth-blocking components stable, ensuring the fixed position of the entire device while allowing the patient to relax their mouth. Furthermore, before the device is inserted into the patient's mouth, the internal hexagonal adjusting nut 511 can be rotated using an internal hexagonal wrench. The worm gear 512 rotates, which in turn drives the worm wheels 510 and the drive shaft 507 on both sides to rotate. The drive shaft 507 then drives the lead screw 508 to rotate. When the lead screw 508 rotates, it causes the support platform 509 on the corresponding side to move back and forth. When the position of the support platform 509 changes, the support point of the spring plate 504 changes when it bends, causing the elastic force generated when bending to also change. This allows the device to be adjusted to suit people with different mouth strength, improving the applicability of the device. Finally, the fluid produced during the operation is collected through the reservoir 104 and absorbed by the absorbent cotton to prevent fluid from flowing back into the throat.
