[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] See also Figures 1 to 5The embodiment of the present utility model discloses an oral photography reflector, comprising a handle 1, a reflector 2, a curved rod 3 and a second connecting portion 4. The curved rod 3 is fixed to the reflector 2 and connected to the second connecting portion 4. The front end of the handle 1 is provided with a first connecting portion 11, and the second connecting portion 4 is detachably connected to the handle 1 through the first connecting portion 11; when placed flat, the curved rod 3 causes the reflector 2 and the handle 1 to form horizontal planes at different heights, that is, when observed from the side angle of the oral photography reflector, the handle 1 and the reflector 2 are not in the same straight line.

[0032] When in use, the existing oral photography reflector is usually a rectangular mirror plate. The operator holds one end of the mirror plate and puts the other end into the patient's mouth to take pictures. However, this oral photography reflector has the problem of being large in area and not compact enough. The utility model connects the reflector 2 and the handle 1 through a curved rod 3 and a second connecting part 4. The reflector 2 is provided in various sizes and can be replaced and removed from the handle 1 according to the size of the patient's mouth, which is convenient to use. Secondly, the curved rod 3 is provided with a certain curvature. When viewed from the side, the handle 1 and the reflector 2 are not in the same straight line. The curvature design of the curved rod 3 offsets the handle 1 and the reflector 2 to different straight lines. When the doctor holds the handle 1, the picture in the reflector 2 is not blocked. Moreover, compared with the inconvenience of holding a whole mirror plate in the existing method, in the utility model, the doctor holds the handle 1 and inserts the reflector 2 into the patient's mouth, which is convenient for operation in the narrow oral environment and more flexible in operation. The design of the handle 1 is conducive to controlling the angle of the mirror, which is convenient for treatment.

[0033] Further, such as Figure 1 and Figure 2 As shown, the curved rod 3 fits the outer periphery of the reflector 2, and the two ends of the curved rod 3 are connected to the second connecting portion 4. Specifically, the curved rod 3 is arranged around the outer periphery of the reflector 2 to form a wrap, preventing the side of the reflector 2 from scratching the patient's mouth, and the two ends of the curved rod 3 are brought together at the second connecting portion 4, which is more structurally stable and not easy to tilt during use.

[0034] Furthermore, the connection method between the second connection part 4 and the first connection part 11 is not limited to threaded connection and clamping, for example, Figure 4 and Figure 5 As shown, the rear end of the second connecting portion 4 is protruding, and the first connecting portion 11 is a fixing hole adapted to the protruding portion of the second connecting portion 4, so as to facilitate replacement of the reflector 2 and the handle.

[0035] Preferably, the material of the curved rod 3 includes but is not limited to plastic and metal. Specifically, plastic is relatively low in cost, easy to manufacture, and lightweight, making it easier to operate; metal is relatively strong, wear-resistant, highly reusable, and has a long service life.

[0036] Preferably, the angle formed by the curved rod 3 and the mirror surface of the reflector 2 is in the range of 115°-145°, which allows the doctor to obtain a better viewing angle during operation and facilitates adjustment to obtain the best shooting angle.

[0037] Preferably, considering the portability and durability of the reflector 2 , the thickness of the reflector 2 is in the range of 2 mm to 5 mm.

[0038] Preferably, the diameter range of the curved rod 3 is 5mm-10mm. Specifically, if the diameter of the curved rod 3 is thicker than the thickness of the reflector 2, the curved rod 3 can provide stronger supporting force, making the overall structure more solid. The curved rod 3 is wrapped around the outer periphery of the reflector 2, protecting the reflector 2 from external collisions to a certain extent, thereby extending the service life of the reflector 2.

[0039] Implementation Method 1

[0040] like Figure 1 As shown, in one embodiment, the reflector 2 is a front teeth segment reflector 21, which is used to photograph the front teeth segment in the patient's oral cavity.

[0041] Preferably, the length of the front teeth segment reflector 21 ranges from 25mm to 35mm, and the width of the front teeth segment reflector 21 ranges from 45mm to 60mm. Models of different lengths and widths can be adapted to patients of different age groups and with different mouth opening sizes.

[0042] Specifically, Figure 1 As shown, the anterior segment reflector 21 is semicircular and is typically used to photograph the anterior segment in the oral cavity. During use, the doctor holds the handle 1, presses the mirror against the patient's tongue or upper oral wall, and rotates the handle 1 to adjust the angle. The anterior segment reflector 21 shows the inner side of the anterior segment, and another doctor photographs the image in the mirror. Compared to traditional oral photography reflectors, the present invention is configured as a reflector 2 plus a handle 1. The curved rod 3 prevents the anterior segment reflector 21 and the handle from being in a straight line from a side view. Due to the design of the curved rod 3, the doctor's line of sight is not blocked when holding the handle 1, resulting in clearer photography. Moreover, compared to the prior art method of using a whole reflector plate, the anterior segment reflector 21 in this embodiment can be completely placed in the patient's oral cavity. The reflector 2 is more compact, making it easier to adjust the angle in the oral cavity. The size of the anterior segment reflector 21 can adapt to the cavity size of most patients on the market, making it easier to disassemble and more convenient.

[0043] Implementation Method 2

[0044] like Figure 2 As shown, in another embodiment, the reflector 2 is a posterior segment reflector 22 for photographing the posterior segment of the patient's oral cavity.

[0045] Furthermore, the length of the posterior teeth segment reflector 22 ranges from 30mm to 45mm, and the width of the posterior teeth segment reflector 22 ranges from 20mm to 30mm. Models of different lengths and widths are available to accommodate patients of different age groups and with different mouth opening sizes.

[0046] Specifically, Figure 2 As shown, the posterior segment reflector 22 is more slender than the anterior segment reflector 21 and is typically used to photograph the posterior segment of the oral cavity. During use, the doctor holds the handle 1 and inserts the posterior segment reflector 22 into the patient's mouth. The doctor adjusts the position and angle of the handle 1 to obtain the best possible image. Compared to the existing technology of a single reflector plate, the present invention uses a curved rod 3 to position the posterior segment reflector 22 and the handle 1 off-line. This allows the doctor to hold the handle 1 without blocking the mirror surface, making oral photography more convenient and easy to operate.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
