Description

Technical Field

[0001] This utility model relates to the field of rubber dam separation technology, and in particular to an oral rubber dam separator. Background Technology

[0002] The rubber dam technique utilizes the elasticity of a rubber sheet, which is perforated and then fitted onto a rubber dam arch. The rubber dam arch is then clamped at the neck of the tooth as a barrier. Finally, the rubber dam is stretched across the spikes of the rubber dam arch to open it, exposing the tooth for treatment. This method isolates the crown of the tooth being treated from the oral cavity. After treatment, the dentist can directly remove the rubber dam arch, thus removing the rubber dam arch, rubber sheet, and rubber dam arch together from the child's mouth. The nursing staff handling the instruments need to separate the rubber sheet from the rubber dam arch; the rubber sheet is discarded, and the rubber dam arch is sterilized.

[0003] However, the elasticity of the rubber dam and the needles on the rubber arch are tightly bound together, even hanging very tightly. When workers separate the rubber dam from the rubber arch, the process is quite cumbersome. They are often splashed with saliva from the rubber dam onto their faces and clothes, causing secondary environmental pollution and posing a risk of infection to the workers. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an oral rubber dam separator, which solves the problem that workers are often splashed with saliva from the rubber dam on their face and clothes when separating the rubber dam cloth from the rubber dam bow.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An oral rubber dam separator includes a separation component for opening the rubber sheet to separate it from the rubber dam arch, and a limiting component disposed on the separation component to limit its opening angle. The separation component includes two movable arms arranged at an included angle, the included angle of which is in the range of 5-15°, connecting seats fixed to one end of each of the two movable arms, and arc-shaped rods integrally formed on one end of each connecting seat. An opening hook is fixed to the bottom of one end of each arc-shaped rod. The bottom cross section of the opening hook is set as trapezoidal, and the pointed surfaces of the two opening hooks are far apart from each other.

[0007] Furthermore, the separation assembly also includes a rotating assembly disposed between one end of the two movable arms, and the rotating assembly is provided with a connecting hook for hooking the rubber barrier to prevent it from springing off. The rotating assembly includes a rotating seat one fixedly disposed at one end of one of the movable arms and a rotating seat two fixedly disposed at one end of the other movable arm, with the rotating seat one rotatably connected to the inner side of the rotating seat two.

[0008] Furthermore, a limiting shaft is rotatably provided between the first rotating seat and the second rotating seat, and a connecting arc rod fixed to the bottom of the limiting shaft is fixed to the connecting hook.

[0009] Furthermore, the limiting component includes limiting slots respectively opened on the side of the two movable arms that are close to each other, and a return spring disposed between the two movable arms. A connecting baffle is fixedly disposed at both ends of the return spring, and a limiting block is fixed on one side of the connecting baffle. The two limiting blocks are respectively matched with the two limiting slots.

[0010] Furthermore, an arc-shaped frame is provided between the two movable arms, and the two movable arms are slidably connected on the inner sides of the two ends of the arc-shaped frame.

[0011] Furthermore, positioning grooves are respectively provided on one side of the middle of the two movable arms, and the two ends of the arc-shaped frame are respectively matched with the two positioning grooves. An arc-shaped stop bar is fixed on one side of the inside of the arc-shaped frame, and the two ends of the arc-shaped stop bar are respectively slidably connected to the two movable arms.

[0012] By employing the above technical solution, this utility model provides an oral rubber dam separator, which, compared with the prior art, has at least the following beneficial effects:

[0013] 1. This utility model uses a separation component to separate the rubber sheet from the rubber barrier bow. By squeezing the two movable support arms, two arc-shaped rods drive two opening hooks to open each other, allowing the rubber sheet to detach from the rubber barrier bow. At the same time, the connecting hooks are hung at the edge of the rubber sheet to prevent the rubber sheet from falling directly and causing saliva on it to splash onto the face and clothes, reducing secondary environmental pollution, lowering the risk of infection for workers, and also reducing the risk of workers' fingers being injured by the sharp object of the rubber barrier bow.

[0014] 2. This utility model uses a rotating component to move the two movable arms towards the center, thereby driving the two opening hooks to open up to each other. It also has a limiting component to effectively prevent the rubber barrier from sliding or shifting during removal, ensuring the stability of the rubber barrier when removed from the rubber barrier bow, thus facilitating its use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Rubber dams and rubber arches are commonly used as auxiliary tools in root canal treatment or other oral surgeries. They effectively isolate teeth from the surrounding oral environment, reducing the risk of infection and improving treatment efficiency. After use, nursing staff need to remove the rubber dam directly from the rubber arch. However, saliva from the rubber dam often splashes onto the face and clothing, causing secondary environmental contamination. To prevent the rubber dam from detaching directly and causing saliva to splash onto the face and clothing, such as... Figure 1 and Figure 2 As shown, an oral rubber dam separator is provided, which consists of a separation component 100 and a limiting component 200. The separation component 100 is used to open the rubber sheet to separate it from the rubber dam arch, and the limiting component 200 is disposed on the separation component 100 and limits its opening angle.

[0024] To effectively reduce saliva splashing during rubber dam removal and ensure safety during separation, the separation assembly 100 includes two movable arms 101 arranged at an angle of 10°. Connecting seats 102 are fixed to one end of each arm 101. Arc-shaped rods 103 are integrally formed at one end of each connecting seat 102. A spreading hook 104 is fixed to the bottom of one end of each arc-shaped rod 103. The arc-shaped rods 103 are inclined downwards, causing the spreading hook 104 to be positioned... The bottom of the movable support arm 101 is designed so that the opening hook 104 can directly hook onto the edge of the rubber barrier, and the rubber barrier does not affect the use of the movable support arm 101, ensuring the flexibility of the movable support arm 101 during use. The bottom cross section of the opening hook 104 is set as trapezoidal, and the pointed surfaces of the two opening hooks 104 are far apart from each other. The pointed surfaces of the opening hooks 104 contact the side of the rubber barrier, so that the rubber barrier can be hung on the opening hooks 104 first, preventing it from falling off directly and causing saliva to splash.

[0025] When one end of the two movable support arms 101 is squeezed, the two arc-shaped rods 103 can respectively drive the two spreading hooks 104 to spread apart, thereby causing the rubber sheet to fall off the rubber barrier. The separation assembly 100 also includes a rotating assembly 106 disposed between one end of the two movable support arms 101, and the rotating assembly 106 is provided with a connecting hook 105 for hooking the rubber barrier to prevent it from springing off. The rotating assembly 106 includes a rotating seat 1061 fixedly disposed at one end of one of the movable support arms 101, and a rotating seat 2 1062 fixedly disposed at one end of the other movable support arm 101. The rotating seat 1061 is located at... The inner side of the rotating seat 1062 is rotatably connected, and a limiting shaft 1063 is rotatably provided between the rotating seat 1061 and the rotating seat 1062. The two movable support arms 101 rotate around the limiting shaft 1063 to ensure the stability of the rotation of the two movable support arms 101. The bottom of the limiting shaft 1063 is fixed with a connecting arc rod 1064 that is fixed to the connecting hook 105. When the two opening hooks 104 are opened at the same time, the connecting hook 105 is hung on the edge of the rubber barrier between the two opening hooks 104, further ensuring that the rubber barrier will not easily fall off and improving the stability when the rubber barrier is separated.

[0026] To prevent the rubber barrier from sliding or shifting during removal and to ensure its stability when removed from the rubber barrier arch, such as... Figure 2 and Figure 3As shown, the specific implementation method is as follows: the limiting component 200 includes limiting slots 201 respectively opened on the side of the two movable arms 101 that are close to each other, and a return spring 202 disposed between the two movable arms 101. Connecting baffles 203 are fixedly disposed at both ends of the return spring 202. A limiting block 204 is fixed to one side of the connecting baffle 203, and the two limiting blocks 204 respectively match the two limiting slots 201. When the two movable arms 101 rotate towards the center, the two connecting baffles 203 compress the return spring 202, causing the return spring 202 to undergo elastic deformation and be compressed. An arc-shaped frame 205 is provided in the middle of the movable support arm 101. Two movable support arms 101 are slidably connected on the inner sides of the two ends of the arc-shaped frame 205. A positioning groove 206 is provided on one side of the middle of the two movable support arms 101. The two ends of the arc-shaped frame 205 are matched with the two positioning grooves 206 respectively. An arc-shaped stop bar 207 is fixed on one side of the inner side of the arc-shaped frame 205. The two ends of the arc-shaped stop bar 207 are slidably connected to the two movable support arms 101 respectively. The movable support arms 101 move within the arc-shaped frame 205. The arc-shaped stop bar also provides a certain limit for the movable support arms 101 to ensure the stability of the movement of the movable support arms 101.

[0027] In actual use, the operator squeezes the two movable support arms 101 towards the middle. The rotating seats 1061 and 1062 on the two movable support arms 101 rotate around the limiting shaft 1063. The two movable support arms 101 drive the opening hooks 104 to rotate through the connecting seats 102 at one end, and the two opening hooks 104 are opened outward. At the same time, the two opening hooks 104 are located at the edge of one side of the rubber barrier, and the connecting hooks 105 are hung on the edge of the rubber barrier between the two opening hooks 104. Then, the edge of the rubber barrier is lifted upward and gently rotated at a certain angle to separate the rubber barrier from the rubber barrier bow. Then, it is slowly released so that the rubber barrier cannot bounce back to the edge of the other side, thereby avoiding the splashing of saliva on it.
