Description

Technical Field

[0001] This utility model relates to the technical field of dental instruments, and in particular to a novel dental endoscope for dental use. Background Technology

[0002] The development of dental endoscopes has a profound technological background. In the early days, medical workers began to explore suitable tools in order to clearly observe the complex and hidden structures inside the oral cavity. The initial dental endoscopes were relatively simple in design, with ordinary lens materials and limited image quality, and the handles were not very comfortable to hold. With the advancement of optical technology, high-quality glass and optical plastics were used to make lenses, which improved the clarity and accuracy of imaging. Anti-fog coating technology also emerged, solving the problem of fogging on the mirror surface affecting observation.

[0003] A dental mirror typically consists of a handle and a lens. Utilizing the principle of light reflection, when light shines on the internal tissues of the mouth, it is reflected onto the lens of the mirror, which then reflects this reflected light back to the doctor's eyes, allowing the doctor to observe the inside of the mouth. During a complete oral examination, the doctor will switch between dental mirrors equipped with plane mirrors and concave mirrors, depending on the area being observed. The plane mirror provides a holistic, proportionate view of the front of the mouth, while the concave mirror allows for better observation of harder-to-see areas by utilizing its light-converging and magnifying properties.

[0004] During oral examinations, doctors need to constantly switch between using oral mirrors equipped with plane mirrors and concave mirrors to obtain a complete picture of the oral cavity, which reduces work efficiency. To address this issue, a new type of oral mirror specifically designed for oral examinations has been proposed. Utility Model Content
