Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, specifically to a dental endoscope used in dentistry. Background Technology

[0002] A dental endoscope, also known as an oral endoscope, is a commonly used medical instrument in dentistry, primarily used to examine oral diseases. Depending on the material, function, and purpose, dental endoscopes can be classified into several types, such as glass dental endoscopes, plastic dental endoscopes, and electronic dental endoscopes.

[0003] Existing dental endoscopes typically have the mirror directly fixed to a support rod to increase the length of the mirror that can be inserted into the oral cavity. However, this fixing method makes it difficult to adjust the angle of the mirror within the narrow confines of the mouth, hindering the observation of complex oral conditions. Therefore, we propose a dental endoscope for dental applications to address the aforementioned problems. Utility Model Content

An oblong groove 705 is provided on the rotating rod connecting block 704, and the rotating rod connecting block 704 is located on top of the extension rod connecting block 703.

[0024] Two symmetrical sliding grooves 101 are provided on both sides of the grip rod 1, and multiple anti-slip patterns 102 are evenly spaced on the outer bottom of the grip rod 1. The top of the grip rod 1 is fixedly connected to the mounting top cover 2, and the bottom of the grip rod 1 is fixedly connected to the mounting bottom cover 5. In this example, by providing multiple anti-slip patterns 102, it is easier to apply force and adjust the angle of the movable mirror component 7 at the top of the grip rod 1.

[0025] The top of the mirror extension rod 3 is slidably connected to the mounting cap 2, and one side of the bottom of the mirror extension rod 3 is slidably connected to the holding rod 1 via a groove 101. The top of the mirror rotation rod 4 is slidably connected to the mounting cap 2, and one side of the bottom of the mirror rotation rod 4 is slidably connected to the holding rod 1 via a groove 101. In this example, by setting the mirror rotation rod 4, it is convenient to control the movable mirror component 7 and adjust the angle, which facilitates observation of the internal oral cavity.

[0029] Working principle: Hold the bottom of the gripping rod 1 with your hand, push the thumb pusher 8 with your thumb, which moves the mirror extension rod 3 upward. The extension rod return spring 602 is compressed. Insert the index finger into the index finger buckle 9 and move the mirror rotation rod 4 upward. The rotation rod return spring 603 is compressed, which in turn moves the movable mirror component 7 out. The thumb stops moving, while the index finger continues to move, causing the mirror rotation rod 4 to slide inside the waist-shaped groove 705 on the rotation rod connecting block 704. This causes the mirror 701 to rotate around the mirror extension rod 3 through the extension rod connecting block 703, adjusting the angle of the mirror 701. At the same time, the supplementary light 702 illuminates the inside of the oral cavity to observe the condition inside the oral cavity.
