DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example

[0034] Reference Figure 1-Figure 6 The present invention provides a technical solution: an opener with a tongue depressing function, comprising a round rod 1 and a tongue depressing mechanism 8, and a threaded column 2 is installed at the outer end of the round rod 1, the tongue depressing mechanism 8 comprises a hollow ball 81, the hollow ball 81 is arranged at a position outside the round rod 1, and a circular groove 9 is arranged on the outer surface of the hollow ball 81, a moving rod 82 is arranged inside the hollow ball 81, and the moving rod 82 is slidably installed inside the hollow ball 81, a pressing plate 83 is arranged at the end of the moving rod 82, and the inside of the moving rod 82 is arranged to be hollow and communicated with the inside of the pressing plate 83.

[0035] In a preferred embodiment, an opening mechanism 3 is provided on the outer surface of the round rod 1, and the opening mechanism 3 includes a sliding block 31, a connecting rod 32 and a suction and drag tube 33. The sliding block 31 is slidably mounted on the outside of the threaded column 2 and is threadedly connected to the limit nut 311 on the threaded column 2. The connecting rod 32 is rotatably mounted on the outer surface of the sliding block 31 and is rotatably connected to the support rod 321 at one end of the connecting rod 32, and an opening plate 322 is provided at the connection. The suction and drag tube 33 is arranged inside the round rod 1, and one end of the suction and drag tube 33 extends out of the inside of the round rod 1. The device opens the patient's mouth. In actual operation, the patient can open his mouth first, and then extend one end of the device into the patient's mouth. In order to facilitate the control of the opening plate 322 to open the mouth, the sliding block 31 needs to be pushed. When the sliding block 31 moves, the connecting rod 32 will be controlled to rotate, thereby controlling the movement of the opening plate 322, and the mouth is opened through the opening plate 322 so that the doctor can treat the patient's teeth.

[0036] While the patient's mouth is stretched open, one end of the suction and drag tube 33 can be moved into the patient's mouth, and the suction and drag tube 33 passes through the inside of the round rod 1 and is connected to an external negative pressure device. Under the action of the negative pressure device, the liquid inside the mouth will be automatically extracted to prevent liquid accumulation from covering multiple pairs of teeth, affecting the doctor's line of sight and making it impossible to treat the teeth, thereby meeting the requirements of use.

[0037] In a preferred embodiment, a rectangular plate 4 is fixedly installed on the outer surface of the round rod 1, and a groove 5 is opened on one side of the rectangular plate 4, and a connecting plate 6 is slidably installed inside the groove 5. One end of the connecting plate 6 is movably installed at the position where the connecting rod 32 and the support rod 321 are connected, which is used to limit the opening plate 322, and the opening plate 322 is set to an arc shape. A rubber sheet 7 is provided on the outer surface of the opening plate 322. When the device controls the movement of the sliding block 31, in order to prevent the connecting rod 32 from moving with the sliding block 31, a rectangular plate 4 is provided on the outside of the round rod 1, and a slidable connecting plate 6 is provided on the inside of the rectangular plate 4. The connecting plate 6 is movably connected to the connection between the connecting rod 32 and the support rod 321, so that the connecting rod 32 can only rotate but cannot move forward, thereby controlling the two opening plates 322 to move toward each other, so as to open the patient's mouth to meet the use requirements.

[0038] In order to facilitate the extrusion and positioning of the pressure plate 83 and enable the pressure plate 83 to stably squeeze and limit the patient's tongue, a placement plate 10 is fixedly installed on the outer surface of the round rod 1, and a sliding groove 11 is opened on the upper surface of the placement plate 10, and a sliding block 12 is arranged inside the sliding groove 11. An elastic plate 13 is fixedly installed on the upper surface of the sliding block 12 for extruding and limiting the pressure plate 83. One end of the elastic plate 13 corresponds to the position of one of the pressure plates 83. A plug-in hole 14 is opened on the outer surface of the elastic plate 13 and passes through the interior of the sliding block 12. A positioning hole 15 is opened on the inner bottom of the sliding groove 11. A positioning pin 16 is inserted into the interior of the positioning hole 15, and the positioning pin 16 passes through the interior of the elastic plate 13 and the sliding block 12.

[0039] In actual use, when the support rod 321 rotates, the hollow ball 81 will be driven to move, and the hollow ball 81 will be controlled to move to the position of one end of the round rod 1, and one end of the round rod 1 will be inserted into the inside of the circular groove 9, and the hollow ball 81 is arranged on the outside of the round rod 1, and before the opening plate 322 enters the inside of the oral cavity, the hollow ball 81 will enter the inside of the oral cavity, and as the hollow ball 81 moves, the hollow ball 81 will be moved to the position above the patient's tongue, and as the hollow ball 81 moves toward one end of the round rod 1, it will squeeze the elastic plate 13, and after the round rod 1 is inserted into the inside of the circular groove 9, the elastic plate 13 will squeeze the pressure plate 83 on the top of the moving rod 82, and press the moving rod 82 to move downward, and control the pressure plate 83 at the bottom end of the moving rod 82 to squeeze the patient's tongue, so that the tongue cannot move at will, and avoid accidentally touching the tongue during tooth treatment, so that the doctor can rest assured to treat the patient's teeth.

[0040] During the tooth treatment process, the device will continuously inject disinfectant or saline into the position of the teeth, which will cause an increase in the liquid inside the oral cavity. When the liquid increases, it will block the doctor's line of sight and make it impossible to treat the teeth normally. Therefore, a bracket 17 is fixedly installed inside the round rod 1, and a round roller 18 is rotatably installed at the inner position of the bracket 17, and a suction and drag tube 33 is slidably connected to the outer surface of the round roller 18 to place the suction and drag tube 33, insert the suction and drag tube 33 into the inside of the round rod 1, and pass it out from the inside of the round rod 1. When treating the teeth, one end of the suction and drag tube 33 can be placed at a position where there is liquid, and the liquid can be automatically sucked out under the action of negative pressure, so that the liquid in the oral cavity is conveniently removed.

[0041] Since the pressing plate 83 in the present device is at room temperature, and the temperature of the pressing plate 83 is much lower than the temperature inside the oral cavity, the pressing plate 83 will feel cold when it touches the tongue. This feeling will cause the patient to feel nervous, thereby causing muscle contraction and affecting the treatment of the teeth. To solve this problem, a heating mechanism 19 is provided inside the hollow ball 81. The heating mechanism 19 includes a warm water bag 191 and a cone thorn 192. The warm water bag 191 is arranged inside the circular groove 9, and an arc groove 21 is provided on the outer surface of the movable rod 82. The cone thorn 192 is fixedly installed on the inner wall of the arc groove 21. The position of the warm water bag 191 corresponds to the position of the round rod 1. One end of the round rod 1 is inserted into the inside of the circular groove 9 for squeezing the warm water bag 191, and the warm water bag 191 corresponds to the position of the cone thorn 192. A baffle 20 is fixedly installed on one end of the round rod 1. The suction and drag tube 33 passes through the inside of the baffle 20 and extends out of the inside of the baffle 20. The length of the round rod 1 is set to 20 cm.

[0042] In actual use, in order to relieve the patient's nervousness, when the hollow ball 81 moves toward one end of the round rod 1, one end of the round rod 1 is inserted into the interior of the hollow ball 81 and squeezes the warm water bag 191, moves the warm water bag 191 toward the interior of the arc groove 21, and squeezes the cone thorn 192, and pierces the warm water bag 191 through the cone thorn 192. At this time, the water in the warm water bag 191 will flow into the inside of the moving rod 82, and the warm water will fall into the inside of the pressing plate 83 at the bottom end of the moving rod 82. Since the pressing plate 83 is made of rubber, the warm water will heat the pressing plate 83, so that the tongue can feel the temperature, so that the patient will not feel nervous due to the low temperature, and the patient can relax, which is convenient for treatment of the patient and meets the requirements of use.

[0043] Specifically, the working process or working principle of an opener with a tongue depressor function is as follows: for adults, they can endure the entire process of dental treatment, but for children, the presence of foreign matter will be clearly felt when the device enters the oral cavity. For example, when filling a child's tooth, an opener is used to open the mouth. During the filling operation, the teeth need to be ground. During the grinding process, the child will obviously feel discomfort and will move his tongue unconsciously. The grinding device is relatively sharp and can easily damage the moving tongue and cause harm to the child. Therefore, this device is designed to solve this problem.

[0044] The device can not only open the patient's mouth but also press the patient's tongue to prevent the tongue from moving around and affecting the normal operation during the teeth grinding process. At the same time, it can also protect the tongue and prevent it from being hurt. The specific operation is to extend one end of the device into the patient's mouth, and then slide the sliding block 31 on the threaded column 2. During the sliding process of the sliding block 31, the connecting rod 32 will be controlled to rotate. At this point, the connecting rod 32 will drive the support rod 321 to rotate and push the opening plate 322 to move toward the patient's face. The device is provided with two opening plates 322, which move towards each other, so that the patient's mouth is opened by the two opening plates 322 to prevent the patient's mouth from closing, so that the doctor can treat the patient's teeth.

[0045] After the device determines the position of the sliding block 31, the limiting nut 311 can be screwed to move the position of the sliding block 31 and fit with the outer surface of the sliding block 31 to limit the sliding block 31. The sliding block 31 will not continue to move forward because the opening plate 322 has been pressed against the inside of the patient's mouth and the opening plate 322 can no longer move, so that the sliding block 31 can no longer move, thereby achieving a stable opening for the patient and facilitating the doctor's operation.

[0046] When the support rod 321 rotates, the hollow ball 81 will be driven to move, and the hollow ball 81 will be controlled to move toward the position of one end of the round rod 1, and one end of the round rod 1 will be inserted into the circular groove 9, and the hollow ball 81 is arranged on the outside of the round rod 1. Before the opening plate 322 enters the oral cavity, the hollow ball 81 will enter the oral cavity, and as the hollow ball 81 moves, the hollow ball 81 will be moved to the position above the patient's tongue. As the hollow ball 81 moves toward one end of the round rod 1, it will squeeze the elastic plate 13. After the round rod 1 is inserted into the circular groove 9, the elastic plate 13 will squeeze the pressure plate 83 on the top of the moving rod 82 and press the moving rod 82 to move downward, controlling the pressure plate 83 at the bottom end of the moving rod 82 to squeeze the patient's tongue, and preventing the tongue from moving at will, avoiding accidentally touching the tongue during tooth treatment, protecting the tongue, and preventing injury.

[0047] When the device is actually used, the position of the elastic plate 13 can be adjusted according to the age of the patient to prevent one end of the elastic plate 13 from pressing against the patient's upper jaw and destroying the integrity of the sticky cotton. The positioning pin 16 is pulled out from the inside of the elastic plate 13, and the movement of the elastic plate 13 is controlled. The movement of the slider 12 drives the elastic plate 13 to move, thereby changing the position of the elastic plate 13. The position of the elastic plate 13 can be adjusted according to actual conditions to meet usage requirements.

[0048] During the operation, the doctor will spray disinfectant inside the oral cavity to disinfect the affected area, so that there is liquid inside the oral cavity. If the patient opens his mouth for a long time, the muscles around the oral cavity, including the lips, cheeks and other muscles, will become fatigued due to the long-term opening of the mouth. Under normal circumstances, these muscles can play a certain role in blocking the saliva in the oral cavity. For example, the lip muscles can maintain a certain tension to prevent saliva from flowing out easily. When the muscles are fatigued due to opening the mouth for a long time, the muscle tension decreases, and the ability to control saliva is also weakened, resulting in an increase in saliva inside the oral cavity. When the amount of saliva increases, it will affect the normal operation. Therefore, the suction and drag tube 33 is used to extract the liquid inside the oral cavity. The suction and drag tube 33 will be connected to the external negative pressure equipment. The suction and drag tube 33 is placed on the liquid, and the liquid can be automatically extracted under the action of negative pressure, which is convenient for the doctor to clearly see the position of the teeth and facilitate the treatment of the teeth.

[0049] When the patient is undergoing dental treatment, since the temperature of the pressing plate 83 is significantly lower than the temperature inside the oral cavity, when the pressing plate 83 contacts the tongue, there will be a cold feeling. This cold feeling will directly make the patient feel nervous, and the patient cannot relax during the operation, which is likely to cause the patient to be nervous. Therefore, in order to relieve the patient's nervousness, the present device, when the hollow ball 81 moves toward one end of the round rod 1, one end of the round rod 1 is inserted into the interior of the hollow ball 81, and squeezes the warm water bag 191, moves the warm water bag 191 toward the interior of the arc groove 21, and squeezes the cone thorn 192, and pierces the warm water bag 191 through the cone thorn 192. At this time, the water inside the warm water bag 191 will flow into the interior of the moving rod 82, and the warm water will fall into the pressing plate 83 at the bottom end of the moving rod 82. Since the pressing plate 83 is made of rubber, the warm water will heat the pressing plate 83, so that the tongue can feel the temperature, so that the patient will not feel nervous due to the low temperature, and the patient can relax, which is convenient for treatment of the patient and meets the requirements of use.
