Description

Technical Field

[0001] This utility model relates to the field of oral diagnosis and treatment technology, specifically to an oral retractor for diagnosis and treatment. Background Technology

[0002] Oral care plays a vital role in maintaining oral health, preventing oral diseases, and treating existing oral conditions. Dentists, through observation, examination, and questioning of patients' symptoms, and utilizing specialized oral examination equipment and techniques, can accurately diagnose common oral diseases such as tooth decay, periodontal disease, oral ulcers, and oral mucosal diseases. This not only helps patients understand their oral health status in a timely manner but also provides a reliable basis for subsequent treatment.

[0003] When performing oral examinations, doctors need to use oral retractors to open the patient's mouth in order to observe the inside of the mouth. However, most oral retractors on the market are similar to clamps, which require doctors to use one hand to support and control them to keep the patient's mouth open. Such oral retractors not only occupy the doctor's hand and increase the difficulty of the examination, but also cause pain or damage to the patient's mouth if too much force is used, which is very inconvenient.
