Description

Technical Field

[0001] This invention relates to the field of dental endodontics, and in particular to a rubber dam suction tube installation device, its usage method, and the suction tube itself. Background Technology

[0002] Rubber dam isolation is a core isolation technique in clinical dental treatment. It uses a flexible rubber dam, along with clamps, frameworks, and other auxiliary tools, to isolate the tooth to be treated, creating a separate, dry, and sterile operating area. It is an important component of modern standardized dental treatment. Its main functions are: Isolation from saliva and moisture: Completely preventing contamination of the treatment area by saliva and gingival crevicular fluid, keeping the area dry and clean—crucial for successful procedures such as fillings, root canals, and tooth preparation (e.g., resin bonding and root canal disinfection require an absolutely dry environment). Protection of oral soft tissues: Preventing damage to the gums, tongue, and buccal mucosa from instruments (e.g., burs, root canal files) and medications (e.g., disinfectants, etching agents) during treatment, while also preventing patients from accidentally swallowing / aspirating instruments or debris. Improved treatment efficiency and quality: Reduced saliva interference, providing the dentist with a clearer field of vision and more precise operations (e.g., preventing instrument slippage during root canal preparation and ensuring stronger material bonding during fillings); it also reduces the number of bacteria in the operating area, lowering the risk of postoperative infection. Improved patient experience: Avoids irritation of the throat by spraying water or debris during treatment, reduces nausea reflex, and is especially suitable for children and people with sensitive throats; in some cases, it can reduce mouth opening time and reduce muscle fatigue.

[0003] Rubber dam isolation can effectively protect both doctors and patients, providing patients with a more professional, safer, and more comfortable treatment experience. In September 2018, the National Medical Licensing Examination Syllabus (Dental Physician / Dental Assistant Physician) added rubber dam isolation, which was officially implemented in 2019. In March 2021, the National Health Commission listed "increasing the usage rate of rubber dam isolation in root canal treatment" as a national oral health quality control improvement goal for 2020 (National Health Commission Letter

[2021] No. 51), requiring provincial quality control centers and oral medical institutions to actively promote and popularize rubber dam isolation.

[0004] When using rubber dam isolation, saliva in the patient's mouth needs to be suctioned out using a saliva suction tube. Normally, after suctioning, the tube needs to be placed outside the mouth until the next suction, which adds inconvenience for the physician. Furthermore, the repeated handling of the suction tube makes it difficult to maintain cleanliness of both the tube and the oral cavity. Therefore, a specialized saliva suction tube installation device is needed, allowing it to remain inside the mouth until the treatment is complete. Summary of the Invention
