Description

Technical Field

[0001] The invention belongs to the technical field of stomatological instruments, and in particular relates to a tongue pulling device for assisting intraoral scanning operations. Background Art

[0002] The Department of Dentistry often requires a lot of delicate intraoral operations, including tooth preparation, periodontal treatment, 3D oral scanning, implant surgery, etc. Tooth preparation is a common treatment operation in oral departments such as endodontics and prosthodontics. It requires the use of instruments to modify the teeth to a shape suitable for further treatment, and on this basis complete the restoration treatment of the crown. Periodontal cleaning is the basic treatment method for periodontal disease in the periodontal department. Various instruments are required to perform delicate operations on the gingival tissue and its surroundings to remove the causes of periodontal disease such as tartar and plaque in the lesion area. With the continuous advancement of oral medicine technology, oral scanning 3D scanners have become an important tool for clinical acquisition of 3D data of patients' mouths. This equipment can provide accurate digital information for restoration production, orthodontic design, etc., greatly improving the efficiency and quality of diagnosis and treatment. However, in actual clinical practice, the above-mentioned delicate intraoral operations often have some challenges, among which the interference of the tongue and the influence of saliva are particularly prominent.

[0003] In oral clinical practice, in order to improve the accuracy and efficiency of intraoral operations, doctors often need to take some measures to pull the tongue to reduce the interference of tongue movement on the operation process. At present, the commonly used tongue pulling scheme in clinical practice is mainly achieved by using a mouth mirror. However, the structure of the mouth mirror is quite different from the softness and flexibility of the tongue tissue, which often fails to achieve the ideal restriction effect when pulling the tongue. The instability of the tongue makes it difficult for the scanning equipment to capture a clear image of the mandible, thus affecting the quality and accuracy of the treatment.

[0004] In addition, the mouth mirror cannot absorb saliva while pulling the tongue. The secretion of saliva is a normal physiological phenomenon in the oral cavity, but the presence of liquid during the three-dimensional scanning of the mandible will interfere with the accuracy of the scanning equipment and reduce the clarity of the image; during tooth preparation and periodontal treatment, the presence of liquid will make the patient uncomfortable, prone to choking or uncontrolled head movement. Therefore, when the saliva secretion is high, the doctor has to suspend the treatment process and the nurse uses a saliva suction tube to clean the saliva. This interruption not only reduces the continuity of the intraoral operation, but also seriously affects the efficiency of the entire intraoral operation process. In order to solve these problems and improve work efficiency and quality, it is urgent to develop a new type of tongue pulling device, which should be able to simultaneously achieve effective pulling of the tongue and timely absorption of saliva, blood and other liquids.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0018] Reference Figure 1 A tongue pulling device for assisting intraoral scanning operation includes an elastic fixing ring 2, the bottom of the elastic fixing ring 2 is fixedly connected with a net-shaped elastic adsorption part 3, the elastic adsorption part 3 is used to cover the tongue 1 and adsorb saliva on the tongue 1 and in the oral cavity, and the side of the elastic fixing ring 2 is fixedly connected with a traction rod 4 for pulling the elastic fixing ring 2 and the elastic adsorption part 3.

[0019] In this embodiment, the elastic fixing ring 2 and the elastic adsorption part 3 are both made of medical grade or food grade elastic materials, which can fit tightly with the tongue body 1, thereby limiting the movement of the entire tongue body 1. The side of the elastic fixing ring 2 is fixedly connected with a traction rod 4, which can facilitate the traction of the elastic fixing ring 2 and the elastic adsorption part 3 to move, thereby adjusting the position of the tongue body 1.

[0020] In this embodiment, a plurality of first adsorption holes 7 are provided on the inner and outer surfaces of the elastic adsorption part 3, and a liquid suction tube 6 is connected to the outer side of the elastic adsorption part 3. The first adsorption holes 7 on the surface of the elastic adsorption part 3 are all connected to the liquid suction tube 6 through the pipeline network inside the elastic adsorption part 3, and the end of the liquid suction tube 6 away from the elastic adsorption part 3 is connected to the liquid suction pump. After the liquid suction pump is turned on, negative pressure can be generated in the liquid suction tube 6 and the pipeline network inside the elastic adsorption part 3, so that the saliva secreted on the tongue 1 and in the oral cavity can be absorbed through the first adsorption holes 7, and the saliva can be discharged smoothly in the end; and the suction force of the first adsorption holes 7 on the inner surface of the elastic adsorption part 3 can make the elastic adsorption part 3 fit more closely with the surface of the tongue 1, thereby further stabilizing the position of the tongue 1 and reducing the interference of the tongue 1 on the operation field of view.

[0021] In this embodiment, the pipette 6 is connected to the bottom of the elastic adsorption portion 3, so as to ensure that the pipette 6 can completely discharge the saliva.

[0022] In this embodiment, the elastic absorption part 3 can be made of latex material or polyurethane material.

[0023] In this embodiment, a plurality of second adsorption holes 8 are evenly arranged on the surface of the elastic fixing ring 2, and the density of the second adsorption holes 8 is greater than the density of the first adsorption holes 7. The second adsorption holes 8 are connected to the pipeline network inside the elastic adsorption part 3 through the pipeline network inside the elastic fixing ring 2, so that the saliva absorbed by the second adsorption holes 8 can eventually be discharged through the liquid pipette 6. The provision of the second adsorption holes 8 enables the elastic fixing ring 2 to effectively fix the root of the tongue 1 while also effectively absorbing the saliva secreted by the root of the tongue 1, thereby preventing the saliva from affecting the operation field of view.

[0024] In this embodiment, the elastic fixing ring 2 is specifically made of natural rubber.

[0025] In this embodiment, a traction hook 5 is fixedly connected to one end of the traction rod 4 away from the elastic fixing ring 2. The traction rod 4 can control the movement of the elastic fixing ring 2, so that the doctor can accurately and effectively pull the tongue 1, so that the doctor has a better operation field of view, and the traction hook 5 on the traction rod 4 can connect the traction rod 4 with the mouth opener or dental floss, so that the doctor can control them simultaneously.

[0026] The method of use of the present invention is:

[0027] First, connect the suction tube 6 to the suction pump built into the dental chair. Before operation, ensure that the first suction hole 7 and the second suction hole 8 can generate sufficient suction through the suction pump. This step is the key to ensure the normal operation of the device's suction function.

[0028] Then, the elastic fixing ring 2 is put onto the root of the tongue body 1, the elastic adsorption part 3 is put onto the tongue body 1, and the traction rod 4 is ensured to be in an easy-to-operate position at this time, and then the traction rod 4 is used to apply appropriate traction force to the root of the tongue body 1 to achieve effective fixation of the tongue body 1.

[0029] Finally, the tongue 1 is pulled in the opposite direction according to the specific location of the treatment operation area. For example, if tooth preparation, three-dimensional scanning or periodontal treatment is required on the left side of the mandible, the tongue 1 is pulled to the right to provide a clear view of the left side of the mandible. During this process, the saliva secreted from the tongue 1 and other parts of the oral cavity will be absorbed by the first adsorption hole 7 and the second adsorption hole 8, and finally discharged into the corresponding collection device through the suction tube 6 and the suction pump.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
