Description

Technical Field

[0001] The present invention relates to the technical field of oral treatment, and particularly to a rubber dam isolation system. Background Art

[0002] In the field of oral treatment, keeping the oral cavity dry is a key prerequisite for operations such as filling teeth and root canal treatment. However, the continuous secretion of saliva in the oral cavity makes it difficult to maintain a dry state in the operation area. The traditional rubber dam isolation method is currently the mainstream tooth isolation method, which realizes the isolation of the affected tooth from other parts of the oral cavity by using an elastic and tough rubber dam cloth, rubber dam clips, and an external bracket. The specific operation process is as follows:

[0003] Rubber dam cloth: The traditional rubber dam cloth is square or circular. Before use, special punching tools are required to punch small holes at specific tooth positions for subsequent fixation.

[0004] Rubber dam clips: Traditional rubber dam clips are usually of a metal U-shaped structure. A special gripper is needed to open them, and the rubber dam cloth is fixed on the tooth through a reserved round hole. This process is not only complex in operation but also has many problems, such as it is difficult to control the clamping position, which easily causes accidental injury to the gums or teeth.

[0005] External bracket: The traditional external bracket is a single U-shaped structure, which cannot be adjusted in size and lacks additional support. During use, the elasticity of the rubber dam cloth will make the external part closely adhere to the patient's lips and the surrounding skin, causing discomfort of dyspnea in some patients with the habit of mouth breathing. At the same time, it will also prevent medical staff from inserting the saliva aspirator into the oral cavity, resulting in the saliva generated in the patient's oral cavity not being sucked out in time, thus causing problems such as choking cough.

[0006] In summary, although the existing rubber dam isolation system can achieve oral isolation to a certain extent, its operation process is complex and has many drawbacks, such as it is difficult to control the clamping position of the rubber dam clips, and the rubber dam cloth closely adheres to the lip skin, causing discomfort to the patient. These problems affect the patient's treatment experience and treatment effect. Therefore, the present invention proposes a rubber dam isolation system to solve the above problems. Summary of the Invention

[0020] 2. Through the cooperation of the threaded holes on the fixed block and the threaded rod, the retainer is convenient to install and disassemble, enabling the retainer to be quickly installed or disassembled according to the treatment requirements, reducing the operation time and effort.

[0021] 3. By providing a rubber base layer in the present invention, the rubber dam perforated cloth is made elastic. By providing an anti-corrosion inner layer, the anti-corrosion performance inside the rubber dam perforated cloth is improved. By providing an antibacterial outer layer, the rubber dam perforated cloth has good antibacterial performance on the outside, which can reduce the growth of bacteria on the surface of the rubber dam perforated cloth, maintain the antibacterial state of the treatment area, and can effectively isolate pollutants such as saliva and blood in the oral cavity, keeping the treatment area dry;

[0022] 4. Through the design of preset sleeve holes in the present invention, the on-site hole punching step is omitted, reducing the operation time and effort. The preset sleeve holes on the rubber dam perforated cloth are sleeved on the dam cloth sleeve, thereby achieving sealing and fixation, and can effectively reduce the gap between the preset sleeve holes and the teeth, thus enhancing the sealing performance of the moisture isolation system and preventing saliva, blood or other pollutants from entering the treatment area;

[0023] 5. By adjusting the depth of the movable rod inserted into the fixed rod, and then the movable rod is fixed by tightening the positioning screw, the length and width of the support frame can be adjusted to adapt to rubber dam perforated cloths of different lengths and widths. A plurality of second retaining protrusions are fixedly arranged on the side wall of the fixed rod, and the dental chair fixing seat is fixed on the headrest handle of the dental chair. Adjust the connecting body to an appropriate bending angle. The provided first retaining protrusion and second retaining protrusion are used to support the edge of the rubber dam perforated cloth on the support frame. These protrusions can effectively prevent the rubber dam perforated cloth from sliding or shifting during the treatment process, enabling it to stably support the edge of the rubber dam perforated cloth and avoiding it from closely adhering to the lip skin, leaving a space for the patient to breathe through the mouth;

[0024] 6. By providing a connecting mechanism in the present invention, it can prevent the elastic rubber dam perforated cloth from detaching from the fixed rod, thereby improving the reliability of the installation of the rubber dam perforated cloth. After the rubber dam perforated cloth is used up, pull the limiting rod outwards. Under the action of the elastic plate, the two arc-shaped connecting plates move in a direction away from each other, causing the arc-shaped connecting plates to separate from the fixed rod and the two anti-slip columns to separate from the rubber dam perforated cloth. At this time, the rubber dam perforated cloth can be removed, realizing the quick replacement of the rubber dam perforated cloth. BRIEF DESCRIPTION OF THE DRAWINGS

A bite pad 26 is fixedly arranged through the side of the retention frame 25 away from the clip wings 21. The retention frame 25 is fixed on the clip wings 21 through the installation mechanisms 22. The patient bites on the bite pad 26. With the biting force of the opposing teeth, the rubber dam sleeve clip 2 is further retained in the vertical direction. At the same time, the retention frame 25 functions as a mouth opener, facilitating the doctor's treatment operation inside the oral cavity.

[0043] A fixing dam cloth 23 is fixedly arranged through the middle position of the top of the clip wings 21. A prefabricated dam hole 27 is formed in the fixing dam cloth 23. A preset sleeve hole 4 is arranged on the rubber dam perforated cloth 1. There is no need to punch holes before use. The inner wall of the preset sleeve hole 4 is thickened. The aperture of the preset sleeve hole 4 is larger than the aperture of the prefabricated dam hole 27. The rubber dam perforated cloth 1 is attached to the inner side of the rubber dam sleeve clip 2. The two sides of the clip wings 21 can be bent and shaped. The teeth to be treated pass through the preset sleeve hole 4 of the rubber dam perforated cloth 1. The preset sleeve hole 4 of the rubber dam perforated cloth 1 and the prefabricated dam hole 27 are passed through the treated teeth. The two sides of the clip wings 21 can be bent and shaped to make them closely adhere to the gums, realizing retention in the horizontal direction.

[0044] As an improvement of the above technical solution, the installation mechanism 22 includes a fixed block 224 which is fixedly arranged on the top of the clamping wing 21. A threaded hole is formed on one side of the fixed block 224 close to the retainer 25.

[0046] As an improvement of the above technical solution, a dam cloth sleeve 24 is fixedly arranged at the middle position of the bottom of the clamping wing 21. The preset sleeve hole 4 reserved on the rubber dam perforated cloth 1 is sleeved and installed on the dam cloth sleeve 24. By sleeving the preset sleeve hole 4 on the rubber dam perforated cloth 1 onto the dam cloth sleeve 24, sealing and fixing can be achieved, which can effectively reduce the gap between the preset sleeve hole 4 and the teeth, thereby enhancing the sealing performance of the moisture isolation system and preventing saliva, blood or other pollutants from entering the treatment area. A prefabricated tooth hole 241 is formed through the dam cloth sleeve 24, and the prefabricated tooth hole 241 is located directly below the prefabricated dam cloth hole 27. The provided prefabricated tooth hole 241 and prefabricated dam cloth hole 27 are convenient for sleeving on the treatment tooth. The longitudinal section of the clamping wing 21 is arc-shaped, and the rubber dam perforated cloth 1 is square or circular.

[0047] As an improvement of the above technical solution, the external oral support frame 3 includes a dental chair fixed seat 31 which is fixedly arranged on the headrest handle of the dental chair. A through hole is arranged at the center of the front surface of the dental chair fixed seat 31 for the headrest handle to pass through. The headrest handle is fixed by two retaining screws. A connecting body 32 is fixedly arranged on one side of the dental chair fixed seat 31. The connecting body 32 can be bent and shaped at any angle, similar to the adjustable lamp pole in a mobile phone stand or floor lamp, and can be adjusted in any direction while maintaining a certain stability.

[0048] One end of the connecting body 32 away from the dental chair fixing seat 31 is fixedly provided with a support frame 35. The support frame 35 is arranged in a U shape. A plurality of first retaining protrusions 36 are fixedly provided on the side walls of the support frame 35. Telescopic mechanisms 33 are fixedly provided through the three sides of the support frame 35 respectively. The telescopic mechanism 33 includes a fixed rod 331. One end of the fixed rod 331 is inserted with a movable rod 333. The installation position of the movable rod 333 can be fixed. A positioning screw 332 is arranged on the side wall of the fixed rod 331. The positioning screw 332 is in threaded cooperation with the fixed rod 331. The movable rod 333 is fixed by screwing the positioning screw 332 tightly. By adjusting the depth of the movable rod 333 inserted into the fixed rod 331 and then fixing the movable rod 333 by screwing the positioning screw 332 tightly, the length and width of the support frame 35 can be adjusted to adapt to the rubber dam perforated cloth 1 with different lengths and widths.

[0049] A plurality of second retaining protrusions 34 are fixedly provided on the side wall of the fixed rod 331. The dental chair fixing seat 31 is fixed on the headrest handle of the dental chair. The connecting body 32 is adjusted to a suitable bending angle. The first retaining protrusions 36 and the second retaining protrusions 34 are provided to support the edge of the rubber dam perforated cloth 1 on the support frame 35. These protrusions can effectively prevent the rubber dam perforated cloth 1 from sliding or shifting during the treatment process, enabling it to stably support the edge of the rubber dam perforated cloth 1 and avoiding it from tightly adhering to the oral skin, leaving a space for the patient to breathe through the mouth.

[0050] As an improvement of the above technical solution, it further includes a plurality of connecting mechanisms for connecting the rubber dam perforated cloth 1 with the fixed rod 331. The connecting mechanism includes arc-shaped connecting plates 501 arranged symmetrically up and down. One end of the arc-shaped connecting plate 501 is provided with an elastic plate 502. One end of the elastic plate 502 away from the arc-shaped connecting plate 501 is provided with an anti-slip column 503. One of the arc-shaped connecting plates 501 away from the elastic plate 502 is provided with an upper fixing plate 504. The other arc-shaped connecting plate 501 away from the elastic plate 502 is provided with a lower fixing plate 505. A connecting hole is arranged in the lower fixing plate 505. A connecting column 506 is slidably arranged in the connecting hole. One end of the connecting column 506 is connected with the upper fixing plate 504. A plurality of wedge-shaped card slots 507 are arranged on the side of the connecting column 506 away from the arc-shaped connecting plate 501. A sliding hole is arranged on one side of the connecting hole. The sliding hole is perpendicular to the connecting hole. One end of the sliding hole is communicated with the connecting hole, and the other end of the sliding hole is communicated with the outside of the lower fixing plate 505. A limiting rod 508 is slidably arranged in the sliding hole. One end of the limiting rod 508 is adapted to the wedge-shaped card slot 507. The other end of the limiting rod 508 extends to the outside of the lower fixing plate 505 and is provided with an adjusting plate 509. A connecting spring 510 is arranged on the outside of the limiting rod 508. One end of the connecting spring 510 is connected with the adjusting plate 509, and the other end of the connecting spring 510 is connected with the lower fixing plate 505.

[0051] The connecting mechanism is used to connect the rubber dam perforated cloth 1 with the fixing rod 331. After supporting the edge of the rubber dam perforated cloth 1 on the support frame 35, take a plurality of connecting mechanisms and install them outside the fixing rod 331. Specifically, place two arc-shaped connecting plates 501 on the upper and lower sides of the fixing rod 331 respectively, then align the connecting column 506 with the connecting hole and insert it. The connecting column 506 slides downward along the inner wall of the connecting hole, causing the two arc-shaped connecting plates 501 to move towards the fixing rod 331 until the arc-shaped connecting plates 501 can no longer move. At this time, the end of the limiting rod 508 is snapped into the wedge-shaped card slot 507 of the connecting column 506 under the action of the connecting spring 510, realizing the quick connection of the two arc-shaped connecting plates 501. The rubber dam perforated cloth 1 is then located between the arc-shaped connecting plate 501 and the fixing rod 331. Positioning holes corresponding to the second retaining protrusions 34 are provided on the arc-shaped connecting plate 501, and the second fixing protrusions 34 are inserted into the positioning holes to prevent the arc-shaped connecting plate 501 from sliding back and forth along the fixing rod 331. At the same time, two anti-slip columns 503 are respectively in contact with the rubber dam perforated cloth 1, thereby clamping the rubber dam perforated cloth 1. The anti-slip columns 503 are made of anti-slip material, which can improve the stability of the rubber dam perforated cloth 1. When both anti-slip columns 503 are in contact with the rubber dam perforated cloth 1, the elastic plate 502 is in a bent state. The elastic plate 502 has elasticity, and through the elastic force of the elastic plate 502, the clamping of the limiting rod 508 and the wedge-shaped card slot 507 can be made more stable. By setting the connecting mechanism, it is possible to prevent the elastic rubber dam perforated cloth 1 from detaching from the fixing rod 331, thereby improving the reliability of the installation of the rubber dam perforated cloth 1. After the rubber dam perforated cloth 1 is used up, pull the limiting rod 508 outwards through the adjusting plate 509. Under the action of the elastic plate 502, the two arc-shaped connecting plates 501 move away from each other, causing the arc-shaped connecting plates 501 to separate from the fixing rod 331, and the two anti-slip columns 503 to separate from the rubber dam perforated cloth 1. At this time, the rubber dam perforated cloth 1 can be removed, realizing the quick replacement of the rubber dam perforated cloth 1.

[0052] The working principle and usage method of the present invention:

[0053] The rubber dam perforated cloth 1 is provided with preset sleeve holes 4. Before use, there is no need to punch holes again. During use, the preset sleeve holes 4 on the rubber dam perforated cloth 1 are sleeved on the dam cloth sleeve 24, so as to achieve preliminary sealing and fixation. Then, the preset sleeve holes 4 of the rubber dam perforated cloth 1 pass through the treated tooth. The two sides of the clamping wings 21 can be bent and shaped to closely adhere to the gums, achieving retention in the horizontal direction. The retention frame 25 is fixed between the clamping wings 21 through the installation mechanism 22. The retention frame 25 is arranged in a U shape, and a bite pad 26 is fixedly arranged through the side away from the clamping wings 21. The patient bites on the bite pad 26. With the biting force of the opposing teeth, the rubber dam clamp 2 is further retained in the vertical direction. At the same time, the retention frame 25 functions as a mouth opener, facilitating the doctor's treatment operation in the oral cavity. The rubber dam perforated cloth 1 is elastic, and an anti-corrosion inner layer 13 is fixedly arranged on its inner side, improving the anti-corrosion performance of the inner side of the rubber dam perforated cloth 1. An antibacterial outer layer 11 is fixedly arranged on the outer side, enabling the outer side of the rubber dam perforated cloth 1 to have good antibacterial performance, which can reduce the growth of bacteria on the surface of the rubber dam perforated cloth 1, maintain the antibacterial state of the treatment area, effectively isolate pollutants such as saliva and blood in the oral cavity, and keep the treatment area dry. The dental chair fixing seat 31 is fixed on the headrest handle of the dental chair. By adjusting the depth of the movable rod 333 inserted into the fixed rod 331, and then the movable rod 333 is fixed by tightening the positioning screw 332, the length and width of the support frame 35 can be adjusted to adapt to rubber dam perforated cloths 1 of different lengths and widths. The connecting body 32 is adjusted to an appropriate bending angle. The first retention protrusion 36 and the second retention protrusion 34 are provided to support the edge of the rubber dam perforated cloth 1 on the support frame 35. These protrusions can effectively prevent the rubber dam perforated cloth 1 from sliding or shifting during treatment, enabling it to stably support the edge of the rubber dam perforated cloth 1 and avoiding it from closely adhering to the lip skin, leaving a space for the patient to breathe through the mouth.
