Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an oral prosthetic support device with a multi-angle positioning mechanism. Background Technology

[0002] During dental restoration, patients need to keep their mouths open to create a large opening so that the dentist can perform the restoration procedure. A support device can support the patient's mouth so that it can remain in a large opening for a long time, facilitating the restoration process and reducing the difficulty for the patient to keep their mouth open for extended periods.

[0003] Existing dental prosthesis support devices are also simple support structures. Some support devices achieve prolonged oral cavity opening by traction. With the help of relatively fixed instruments on the outside, the patient's head is difficult to move, which is not conducive to adjusting the head posture during dental restoration. Other dental support devices are completely embedded in the patient's oral cavity, using upper and lower structures to open the patient's oral cavity. Although the above structures have solved the problems of traction structures, they still have problems such as limited support angles, difficulty in changing angles, occupation of a large space in the oral cavity, and limitations on the restoration area and angle for dentists during dental restoration operations. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an oral restoration support device with a multi-angle positioning mechanism. During the oral restoration process, the positions of the two support legs can be adjusted at multiple angles, dynamically adjusting according to the oral restoration process and the patient's oral feedback. This further improves the efficiency of oral restoration, reduces patient discomfort during the process, and ensures a smooth and stable oral restoration.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: An oral prosthodontic support device with a multi-angle positioning mechanism includes a support bracket with a support leg at its lower end. The support bracket includes two arc-shaped support bodies with internal grooves. The support leg is slidably connected within the groove. Each support leg includes at least two support legs, each of which is slidably connected to a corresponding groove. The support leg has contractile elasticity and is normally in an extended state. Each support leg includes a support base slidably connected to the groove. The lower end of the support base is rotatably connected to an elastic telescopic rod via a damping shaft. The telescopic end of the elastic telescopic rod is fixed to an occlusal body. The occlusal body includes a U-shaped occlusal block with an elastic pad on its inner wall.

[0006] Preferably, the support leg further includes at least one second support leg, which is detachably connected to the inner wall of the slide groove.

[0007] Preferably, the elastic telescopic rod of the support leg is straight or curved.

[0008] Through the above structural design, the specifications of the elastic telescopic rod can be selected according to the patient's oral environment and the requirements of oral restoration. The arc shape of the elastic telescopic rod can face inward or outward. The oral cavity wall has a certain elasticity and can accommodate the outward arc part. At the same time, the arc part can also play a supporting expansion role, further improving the actual operating space in the oral cavity and facilitating oral restoration operations.

[0009] Preferably, the upper end of the support body is also provided with multiple negative pressure suction cups, which are connected to corresponding elastic telescopic rods. During the contraction of the elastic telescopic rods, the residual gas in the negative pressure suction cups is further extracted.

[0010] During the patient's oral occlusion process, the elastic telescopic rod can be used to further remove some of the residual gas in the negative pressure suction cup, further improving the adhesion strength between the negative pressure suction cup and the hard palate at the top of the patient's mouth, further enhancing the stability of the overall structure in the patient's mouth, and ensuring the smooth and stable progress of oral restoration.

[0011] Preferably, the elastic telescopic rod includes a telescopic rod cylinder, a sealing piston is slidably connected to the inner wall of the telescopic rod cylinder, the telescopic end is fixedly connected to the sealing piston, and an adjustment chamber is formed between the side of the sealing piston away from the support body and the telescopic rod cylinder, and the adjustment chamber is connected to the corresponding negative pressure suction cup.

[0012] Preferably, the sealing piston forms a receiving chamber between the side near the support body and the telescopic rod cylinder, and a flow guiding component is provided in the receiving chamber to connect the adjustment chamber with the corresponding negative pressure suction cup.

[0013] The above structural design ensures the airtight connection between the regulating chamber and the negative pressure suction cup, preventing the regulating chamber from effectively extracting gas from the negative pressure suction cup due to sealing issues, thus preventing the negative pressure suction cup from achieving the negative pressure adsorption effect.

[0014] Preferably, the flow guiding assembly includes a relatively fixed flow guiding cylinder one, one side wall of the flow guiding cylinder is connected to a negative pressure suction cup through a flow guiding joint, a flow guiding cylinder two is slidably connected inside the flow guiding cylinder one, the end of the flow guiding cylinder two is fixed to a sealing piston and connected to an adjustment chamber, and an elastic element one is provided between the flow guiding cylinder one and the flow guiding cylinder two.

[0015] Preferably, the flow guiding assembly includes a flow guiding pipe disposed in the receiving chamber, the first end of the flow guiding pipe passing through the sealing piston and communicating with the adjustment chamber, the second end communicating with the corresponding negative pressure suction cup, and an elastic element II disposed in the receiving chamber.

[0016] Preferably, the biting body further includes a rotating joint, the first side of the rotating joint being rotatably connected to the biting block in a first direction, and the second side of the rotating joint being rotatably connected to the telescopic end of the elastic telescopic rod in a second direction, wherein the first direction and the second direction intersect.

[0017] Preferably, a telescopic joint is provided between the two supporting bodies, and the two supporting bodies are controlled to slide relative to each other in the same horizontal plane by means of the telescopic joint.

[0018] The beneficial effects of this invention are as follows: Compared to existing technologies, the above structural design provides independent support for the oral cavity by placing two main support bodies at the top of the hard palate and supporting legs between the main support bodies and the lower teeth. This structure allows for free head movement, facilitating oral restoration. Furthermore, the supporting legs make point contact with the lower teeth, providing effective support at the base of the main support bodies. This simplifies the overall structure, reducing the space required for oral restoration and simplifying the procedure. During restoration, the positions of the supporting legs can be adjusted at multiple angles based on the process and patient feedback, further improving efficiency, reducing discomfort, and ensuring a smooth and stable restoration process.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] To address the problems mentioned in the background art, see Appendix Figure 1 -Appendix Figure 10 A dental restoration support device with a multi-angle positioning mechanism includes a support bracket 100 and a support leg 300 at the lower end of the support bracket 100. The support bracket 100 is fitted to the front two-thirds of the hard palate in the oral cavity, and the support leg 300 is pressed against the lower teeth in the oral cavity. The support bracket 100 and the support leg 300 can form an independent support structure inside the patient's oral cavity, which can support the upper and lower parts of the patient's oral cavity, making it easier for the patient's oral cavity to be in a large open state for a long time, and facilitating the normal and stable progress of dental restoration.

[0032] Specifically, the support bracket 100 includes two arc-shaped support bodies 110. The arc-shaped support bodies 110 follow the same direction as the teeth at the top of the oral cavity, and fit the support bodies 110 against the hard palate and are located inside the teeth, ensuring that the support bodies 110 can be in a relatively stable state during the later support process. A groove 111 is opened inside the support body 110, and the support legs 300 are slidably connected in the groove 111. Depending on the position of the tooth to be repaired, the support legs 300 can be slid to a position away from the repair area, such as the inside of the oral cavity, so as to avoid interference with the oral repair area and facilitate efficient oral repair.

[0033] Furthermore, the support leg 300 includes at least two support legs 3001, which are slidably connected to corresponding grooves 111. The two support legs 3001 are positioned on both sides to provide support, ensuring the stability of the support body 110 against the patient's oral cavity wall. At the same time, the support body 110 is located inside the upper teeth, and the support legs 3001 are against the lower teeth. The support legs 3001 are tilted inward at the top. In the vertical projection plane, the directions of the two support legs 3001 intersect each other, forming a virtual support triangle structure, which further ensures the stability of the overall structure against the oral cavity.

[0034] The support leg 300 here is retractable and normally extends. When compressed, the support leg 300 retracts, and in a relatively stable state, it supports the patient's oral cavity. At the same time, when the patient is fatigued in a certain occlusal position, the dentist can slightly adjust the range of mouth opening and closing during oral restoration, regulating pressure changes and opening state to avoid oral fatigue caused by maintaining one posture for a long time. In addition, by adjusting the position of the support leg 300 in different adjacent positions, the position of the compression at the bottom of the support leg 300 can be changed to avoid continuous pressure on a single area of ​​the lower teeth, which could lead to local discomfort and damage.

[0035] The support leg 300 includes a support base 310 slidably connected to the slide groove 111. The lower end of the support base 310 is rotatably connected to an elastic telescopic rod 320 via a damping pivot 311. The elastic telescopic rod 320 can deflect relative to the support base 310 at a predetermined angle. The specific deflection angle is determined according to the position of the lower teeth at the support position. The telescopic end 323 of the elastic telescopic rod 320 is fixed with a biting body 330. The biting body 330 includes a U-shaped biting block 331. An elastic pad 332 is provided on the inner wall of the biting block 331. The biting body 330 bites with the lower teeth. The U-shaped biting block 331 can be fitted onto the outside of the teeth to ensure that the biting body 330 and the support leg 300 are in a relative position during the biting state, thus preventing slippage.

[0036] The occlusal block 331 here is made of a metal material with a certain degree of expansion elasticity. The opening side can be appropriately expanded to fit on the outside of teeth of different sizes. The elastic pad 332 here can be made of elastic materials such as medical rubber, which can fit tightly with the teeth, further ensuring the stability of the overall occlusal state of the occlusal body 330, ensuring the stability of the support leg 300 between the support body 110 and the lower teeth, and ensuring the normal progress of oral restoration.

[0037] It should be noted that, in order to ensure the overall stability of the support leg 300, the support leg 300 needs to be slid to the position above the lower tooth, and the tilt direction of the support leg 300 should be controlled along the width direction of the tooth. This allows for occlusal support through the occlusal body 330, avoiding excessive tilt angle along the length of the tooth, preventing the support leg 300 from sliding during occlusion, and ensuring the relative stability of the support leg 300 and the overall structure.

[0038] In summary, through the above structural design, the two supporting bodies 110 are positioned at the top of the hard palate within the oral cavity for support, while the supporting legs 300 are positioned between the supporting bodies 110 and the lower teeth for further support. This structure provides excellent independent support for the oral cavity without the need for external structures, allowing the patient's head to move freely and facilitating oral restoration. Furthermore, the supporting legs 300 make point contact with the lower teeth, and the two supporting legs 300 provide good support at the bottom of the supporting bodies 110, simplifying the overall structure and minimizing the space occupied within the oral cavity, thus facilitating oral restoration procedures. During oral restoration, the positions of the two supporting legs 300 can be adjusted at multiple angles, dynamically adjusting based on the restoration process and the patient's oral feedback, further improving the efficiency of oral restoration, reducing patient discomfort, and ensuring a smooth and stable restoration process.

[0039] Furthermore, the support leg 300 also includes at least one second support leg 3002, which is detachably connected to the inner wall of the slide 111. According to the patient's oral cavity support needs, the second support leg 3002 can be added on the basis of the first support leg 3001. The position of the second support leg 3002 is determined according to the actual support needs. The second support leg 3002 can also slide between the slide 111 and can be dynamically adjusted.

[0040] The support leg 2 3002 and the slide groove 111 can be engaged by an existing slide rail engagement structure. A notch can be made on one side of the slide groove for the protrusion on the top of the support leg 2 3002 to slide in, so as to achieve detachable engagement. The aforementioned detachable structure can also be other engagement structures in the existing technology, so as to achieve quick installation of the support leg 2 3002 and ensure relative stability during the support process.

[0041] See attached document Figure 6 The elastic telescopic rod 320 of the support leg 300 can be straight or curved. The specifications of the elastic telescopic rod 320 are selected according to the patient's oral environment and the requirements of oral restoration. The curve of the curved elastic telescopic rod 320 can face inward or outward. The oral cavity wall has a certain elasticity and can accommodate the outward curved part. At the same time, the curved part can also play a supporting and expanding role, further improving the actual operating space in the oral cavity and facilitating oral restoration operations.

[0042] Furthermore, multiple negative pressure suction cups 200 are also provided on the upper end of the support body 110. After the support body 110 is attached to the top of the oral cavity, appropriate squeezing of the negative pressure suction cups 200 can expel most of the gas inside the negative pressure suction cups 200. Under the action of negative pressure, the negative pressure suction cups 200 can be attached to the top of the oral cavity, realizing the initial fixation of the support body 110. The support body 110 can be in a relatively stable position at the top of the oral cavity, which facilitates subsequent angle adjustment and position change of the support legs 300, further simplifying the operation process and improving the efficiency of oral restoration.

[0043] At least three negative pressure suction cups 200 are selected and located at the extreme positions on both sides of the arc and the apex position in the middle, respectively, to ensure the stability of the negative pressure adsorption of the support body 110 on both sides, which is especially suitable for the structure of the support bracket 100 with a larger size.

[0044] Furthermore, the negative pressure suction cup 200 is connected to the corresponding elastic telescopic rod 320. During the contraction of the elastic telescopic rod 320, the residual gas in the negative pressure suction cup is further extracted. Through the above structural design, during the patient's oral occlusion process, the elastic telescopic rod 320 can be used to further extract some of the residual gas in the negative pressure suction cup 200, further improving the adsorption strength between the negative pressure suction cup 200 and the hard palate at the top of the patient's oral cavity, further enhancing the stability of the overall structure in the patient's oral cavity, and ensuring the smooth and stable progress of oral restoration.

[0045] Similarly, during the process of removing the support body 110 after the completion of oral restoration, the gas inside the elastic telescopic rod 320 can be squeezed into the corresponding negative pressure suction cup 200 by pulling the elastic telescopic rod 320 in the opposite direction, thereby controlling the pressure rise inside the negative pressure suction cup 200, reducing the effect of negative pressure adsorption, and finally achieving the rapid removal of the support body 110.

[0046] Specifically, the elastic telescopic rod 320 includes a telescopic rod cylinder 321, with a sealing piston 322 slidably connected to the inner wall of the telescopic rod cylinder 321. The telescopic end 323 is fixedly connected to the sealing piston 322. An adjustment chamber 3201 is formed between the side of the sealing piston 322 away from the support body 110 and the telescopic rod cylinder 321. The adjustment chamber 3201 is connected to the corresponding negative pressure suction cup 200. During the process of the patient occluding the overall structure, the elastic telescopic rod 320 is compressed. During this process, the sealing piston 322 moves towards the support body 110, and the space inside the adjustment chamber 3201 gradually increases. As the space inside the adjustment chamber 3201 increases, the gas inside the negative pressure suction cup 200 is extracted. Conversely, during the process of stretching the elastic telescopic rod 320, the space inside the adjustment chamber 3201 gradually decreases, and the gas inside the adjustment chamber 3201 is squeezed into the corresponding negative pressure suction cup 200, increasing the pressure inside the negative pressure suction cup 200, which facilitates the overall disassembly of the support body 110.

[0047] A receiving chamber is formed between the sealing piston 322 near the support body 110 and the telescopic rod cylinder 321. A flow guiding component 340 is provided in the receiving chamber. The flow guiding component 340 connects the regulating chamber 3201 with the corresponding negative pressure suction cup 200. The flow guiding component 340 is located in the middle to guide the airflow, so as to ensure the sealing of the connection between the regulating chamber 3201 and the negative pressure suction cup 200. This avoids the regulating chamber 3201 from being unable to effectively extract the gas in the negative pressure suction cup 200 due to sealing problems, which would prevent the negative pressure suction cup 200 from achieving the negative pressure adsorption effect.

[0048] Please refer to the appendix for details. Figure 7 Appendix Figure 8 As a first embodiment of the flow guiding assembly, the flow guiding assembly 340 includes a relatively fixed flow guiding cylinder 341. The side wall of the flow guiding cylinder 341 is connected to the negative pressure suction cup 200 through the flow guiding connector 342. A flow guiding cylinder 344 is slidably connected inside the flow guiding cylinder 341. The end of the flow guiding cylinder 344 is fixed to the sealing piston 322 and connected to the adjustment chamber 3201. An elastic element 343 is provided between the flow guiding cylinder 341 and the flow guiding cylinder 344. The elastic element 343 can be selected as a spring structure. Under normal conditions, the elastic element 343 pushes the flow guiding cylinder 344. At the position extending outwards, during the patient's oral occlusion, the telescopic end 323 is forced to compress the sealing piston 322. As the sealing piston 322 moves inwards, it drives the second guide tube 344 to move inwards simultaneously. At the same time, the second guide tube 344 and the first guide tube 341 are in a sealed sliding connection. The second guide tube 344 is in a state of communication with the adjustment chamber 3201. The airflow in the negative pressure suction cup 200 passes through the guide connector 342, the first guide tube 341, and the second guide tube 344 in sequence and is finally sucked into the adjustment chamber 3201, thereby enhancing the negative pressure in the negative pressure suction cup 200.

[0049] As a second embodiment of the flow guiding assembly, the flow guiding assembly 340 includes a flow guiding pipe 346 disposed in the receiving chamber. The first end of the flow guiding pipe 346 passes through the sealing piston 322 and is connected to the adjustment chamber 3201, and the second end is connected to the corresponding negative pressure suction cup 200. An elastic element 345 is disposed in the receiving chamber.

[0050] The aforementioned flow guide pipe 346 can be a flexible hose structure, which bends and changes synchronously with the movement of the sealing piston 322. Alternatively, the flow guide pipe 346 can be a rigid pipe. When a rigid pipe is selected, the flow guide pipe 346 passes through the sealing piston 322 and is slidably connected to it, requiring deformation and modification of the sealing piston 322. Meanwhile, the elastic element 345 can be a spring structure or other columnar elastic material to ensure that the sealing piston 322 automatically returns to its initial position when there is no pressure.

[0051] Furthermore, the occlusal body 330 also includes a rotating joint 333. The first side of the rotating joint 333 is rotatably connected to the occlusal block 331 in a first direction. Through the above structural design, the occlusal block 331 can rotate around the axis of the rotating joint 333. Through the above structural design, the deflection angle of the occlusal block 331 can be adjusted according to the position of the support base 310, so that the occlusal block 331 can be inserted into a predetermined position to bite and lock into position with the teeth. The second side of the rotating joint 333 is rotatably connected to the telescopic end 323 of the elastic telescopic rod 320 in a second direction. The first direction and the second direction intersect. The second side of the rotating joint 333 can be designed as an arc-shaped deflection joint, which can control the rotating joint 333 and the occlusal block 331 to deflect inward or outward by a predetermined angle, further ensuring that the occlusal block 331 fits the teeth and can better fit with teeth in different positions, further enhancing the biting effect of the occlusal block 331. The rotation angle of the rotating joint 333 along the second direction should be limited to avoid the situation where the support is unstable due to excessive rotation angle.

[0052] Please refer to the appendix for details. Figure 7 The bottom of the rotating joint 333 is disc-shaped. The first direction mentioned above is the direction of deflection along the circumference of the bottom of the rotating joint 333. Applying torque to the occlusal block 331 can control the occlusal block 331 to deflect around the axis of the rotating joint 333. The second direction mentioned above is also an arc-shaped direction. The arc-shaped direction is similar to the attached... Figure 7The mid-sections intersect, and by applying a force perpendicular to the cross section to the occlusal block 331, the occlusal block 331 can be pushed to drive the rotating joint 333 to swing in and out along the aforementioned arc tangent, ultimately achieving adjustment of the position of the end occlusal block 331. Through the combination of the above dual adjustment directions, the occlusal block 331 can be adjusted to deflect to a suitable angle at any position to occlude with the lower teeth at different positions, ensuring the stability of the oral restoration support.

[0053] A telescopic joint 120 is provided between the two support bodies 110. The telescopic joint 120 controls the two support bodies 110 to slide relative to each other in the same horizontal plane. Through the above structural design, the distance between the two support bodies 110 can be adjusted by the telescopic joint 120 to adapt to the size of the roof of the patient's mouth and meet the oral restoration needs of patients of different ages. After the negative pressure adsorption of the support bodies 110 on both sides is stable, the support bracket 100 is in a relatively stable state and will not slide relative to each other in the horizontal plane.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
