Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to oral cavity medical equipment, especially relate to an oral photography mouth gag. BACKGROUND
[0002] Oral photography plays a vital role in dental diagnosis and research, and is often used to record information such as the shape, arrangement and color of teeth, so as to facilitate diagnosis, treatment planning and treatment effect evaluation. However, the traditional oral photography operation requires at least two medical staff to cooperate. One medical staff is responsible for shooting, and the other medical staff needs to assist in pulling open the patient's lips and placing a background plate in the oral cavity to improve the shooting effect. This operation method not only increases the labor cost, but also increases the operation complexity, and it is often difficult to achieve efficient operation in a limited resource diagnosis and treatment environment.
[0003] In order to solve the above problems, the patent designs an oral photography mouth gag. CONTENT OF THE UTILITY MODEL
[0004] In view of the defects in the prior art, the utility model provides an oral photography mouth gag, which makes the oral photography operation more simple and fast. By using the mouth gag, one medical staff can independently complete the oral photography, greatly improving the work efficiency and reducing the work burden of the medical staff.
[0005] The oral photography mouth gag provided by the utility model comprises a main body for supporting the lips and a detachable background plate connected to the main body. The main body is "O" shaped and has an inner ring and an outer ring. The main body forms a lip groove on the side facing the lips between the inner ring and the outer ring, and forms a connecting part on the side away from the lips. The connecting part is provided with a slot, and the background plate is provided with a bolt adapted to the slot.
[0006] The working principle of the oral photography mouth gag provided by the utility model is as follows: when in use, the main body is worn to support the lips, and then the required background plate is installed on the main body. After wearing, the inner ring is located in the lips, the outer ring is located outside the lips, and the lips are clamped in the lip groove. Since the main body is "O" shaped, the lips of the patient can be supported after wearing. The background plate is fixed in the slot of the main body by the bolt, so as to be firmly connected and not easy to loosen during use.
[0007] The oral photography mouth gag provided by the utility model not only can effectively pull open the lips of the patient, but also is provided with a replaceable background plate on the main body, so that the oral photography operation is more simple and fast. By using the mouth gag, one medical staff can independently complete the oral photography, greatly improving the work efficiency and reducing the work burden of the medical staff.
[0008] According to an embodiment of the utility model, the material of the main body is elastic rubber.
[0009] According to an embodiment of the utility model, the connecting part is further provided with a magnet, and the background plate is provided with a ferromagnetic body for attracting the magnet.
[0010] According to an embodiment of the utility model, the insertion slot is multiple. BRIEF DESCRIPTION OF DRAWINGS
[0011] In order to more clearly illustrate the specific embodiment of the utility model or the technical scheme in the prior art, the drawings needed to be used in the specific embodiment or the prior art description will be briefly introduced below.In all the drawings, similar elements or parts are generally identified by similar reference numerals.The elements or parts in the drawings are not necessarily drawn according to the actual proportion.

[0013] REFERENCE NUMERALS
[0014] 1-inner ring, 2-outer ring, 3-lip slot, 4-background plate, 6-latch, 7-insertion slot, 8-magnet. DETAILED DESCRIPTION
[0015] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings.The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, therefore only as an example, and cannot limit the protection scope of the utility model.
[0016] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meaning understood by the technical personnel in the field of the utility model.
[0017] REFERENCE Figure 1 The opener for oral photography provided in the embodiment comprises a main body for opening the lips and a background plate 4 detachably connected to the main body, the main body is in the shape of "O" and has an inner ring 1 and an outer ring 2, the main body forms a lip slot 3 on the side facing the lips between the inner ring 1 and the outer ring 2 and forms a connecting part on the side away from the lips, the connecting part is provided with an insertion slot 7, and the background plate 4 is provided with a latch 6 for adapting to the insertion slot 7.
[0018] In use, the main body is first worn to open the lips, and then the required background plate 4 is installed on the main body;after wearing, the inner ring 1 is located in the lips, the outer ring 2 is located outside the lips, and the lips are clamped in the lip slot 3, since the main body is in the shape of "O", the lips of the patient can be opened after wearing;the background plate 4 is fixed in the insertion slot 7 of the main body through the latch 6, so as to be firmly connected and ensure that it is not easy to loosen during use.
