Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, in particular to a three-camera oral digital viewing instrument. Background Art

[0002] Currently, many dental departments and professional dental clinics in both China and abroad use digital oral viewers or oral endoscopes. Doctors use cameras to capture the oral cavity and display it in real time on a computer, facilitating clinical examinations and providing relevant medical records and symptoms. This provides a more comprehensive basis for doctors to diagnose patients' illnesses, making oral examinations particularly important.

[0003] Due to the limited space in the oral cavity, in order to better observe the conditions inside the oral cavity, the lenses of current oral observation equipment are generally close-focus lenses, which are conducive to close-focus photography in the small space inside the oral cavity.

[0004] However, if the doctor needs to conduct a targeted examination of the patient's dental lesions, especially the health of the tissues surrounding the teeth and the entire oral cavity, the existing digital oral viewer with a single focusing lens, either autofocus or manual focus, can only take three clear images with different fixed focal lengths at one time, which often cannot be achieved. At the same time, autofocus and manual focus cannot be used at the same time. Due to its focal length limitation, it is only possible to change devices with different focal lengths one by one for observation. The same patient needs to process several types of photos and videos. Therefore, while taking clear pictures of the targeted teeth, it is difficult to take clear pictures of the surrounding tissues and the entire oral cavity. Therefore, it is necessary to improve the existing digital oral viewer so that the digital oral viewer, or oral endoscope, can clearly take pictures of the condition of the teeth and surrounding tissues, as well as the entire oral cavity, so that doctors can make a comprehensive diagnosis of oral patients. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a three-camera oral digital viewer, which solves the problem that the existing digital oral viewer cannot take into account both manual focus shooting and automatic focus shooting at the same time.
