Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oral photography equipment, in particular to an adjustable oral reflection board. BACKGROUND

[0002] Oral photography is particularly important in the treatment process of orthodontics or oral repair, and perfect picture data can record the changes of teeth during the entire treatment process of the patient, which is convenient for doctors to diagnose, develop treatment plans, academic exchanges and case reviews.

[0003] Oral photography generally uses a single-lens reflex camera, a macro lens, and a macro flash to take pictures, and uses auxiliary pullers, background boards, and reflection boards to assist in shooting. Among them, compared with ordinary integrated digital cameras, single-lens reflex cameras can replace lenses and macro flashes, have small imaging distortion, fast focusing speed, and can control the depth of field; the macro lens has the characteristics of flat phase, small distortion, sufficient contrast of the image, and high resolution, and can select the appropriate lens focal length according to the focusing distance; among the macro flash, the ring flash has a wider application range, and the double-head or multi-head flash has a shadow in the molar area when shooting pictures, but can effectively prevent front reflection; the puller is generally divided into three types: small mouth angle hooks (occlusal surface), W double-head mouth angle hooks, and circular mouth angle hooks, which are used when shooting the front, side, and occlusal surface of the patient; the background board is also divided into black, gray, and portrait backgrounds, which have different scene applications.

[0004] However, in the traditional reflection board, although the appropriate type of reflection board can be selected according to the three different shooting positions of the occlusal surface, the buccal side, and the lingual palatal side, when shooting a full dental arch, due to the different sizes of the patient's mouth opening and the different widths of the dental arch, using the same size of reflection board for shooting will cause discomfort due to the reflection board being too wide to open the patient's mouth, or the patient's dental arch cannot be fully displayed in the reflection board due to the reflection board being too narrow, resulting in a less-than-expected final image. SUMMARY

[0005] Therefore, it is necessary to provide an adjustable oral reflection board that can adjust its width according to the size of the patient's mouth opening and the width of the dental arch.

[0034] As Figure 1As shown, in one embodiment, an adjustable oral cavity reflector comprises a holding part 200, a first reflector lens 110, a back plate 120, a connecting part 300 and two extension lenses 400. The holding part 200 is provided with an adjusting button 210 which is in sliding connection with the holding part 200. The first reflector lens 110 is installed at one end of the holding part 200, and the mirror surface of the first reflector lens 110 faces the side where the adjusting button 210 is located. The back plate 120 is installed at the same end of the holding part 200 as the first reflector lens 110, and there is a gap between the back plate 120 and the first reflector lens 110, forming a cavity. The connecting part 300 is installed inside the cavity, and one end of the connecting part 300 is installed on the adjusting button 210. The two extension lenses 400 are both installed inside the cavity and fixedly connected to the other end of the connecting part 300.

[0035] The adjustable oral cavity reflector described above is slid along the direction close to the first reflector lens 110 to adjust the adjusting button 210, the connecting part 300 drives the extension lenses 400 to perform outward expansion movement, at this time the width of the reflector is expanded. The adjusting button 210 is slid along the direction away from the first reflector lens 110, the connecting part 300 drives the two extension lenses 400 to perform inward contraction movement, at this time the width of the reflector is reduced. The device has simple structure, can change the width of the mirror surface to meet the oral cavity photography of patients with different mouth opening sizes and different tooth row width degrees, is suitable for most people such as adults and children, is convenient for medical staff to operate, and can improve the efficiency and quality of clinical oral cavity photography work.

[0036] In this embodiment, the connecting part 300 comprises a connecting rod 310 and two rotating rods 320. One end of the connecting rod 310 is fixedly installed on the adjusting button 210. The two rotating rods 320 are respectively fixedly connected to the two extension lenses 400, and the two rotating rods 320 are both rotationally installed at the other end of the connecting rod 310.

[0037] In this embodiment, the connecting rod 310 comprises a first rod 311 and a second rod 312. One end of the first rod 311 is fixedly installed on the adjusting button 210, the other end of the first rod 311 is perpendicularly connected to the center point of the second rod 312, and the two rotating rods 320 are both rotationally installed at the two end portions of the second rod 312.

[0038] Specifically, the adjusting button 210 is slid along the direction close to the first reflector lens 110, the connecting rod 310 moves along the same direction, and drives the two extension lenses 400 to move away from the one end of the holding part 200 to perform relative rotation, at this time the transverse width of the reflector is increased. After the oral cavity photography is completed, the adjusting button 210 is slid along the direction away from the first reflector lens 110, the connecting rod 310 moves along the same direction, and drives the two extension lenses 400 to move away from the one end of the holding part 200 to perform relative rotation, at this time the transverse width of the reflector is reduced.

[0039] It should be noted that in the above process, the first rod 311 is fixed at the connection with the second rod 312, and the two always remain in a vertical connection state. The two rotating rods 320 rotate with the second rod 312, and the inner angle of the two rotating rods 320 and the second rod 312 changes during rotation, driving the two extending lenses 400 to rotate around the point, so that the part of the two extending lenses 400 extending out of the first reflecting lens 110 and the back plate 120 is enlarged or reduced, thereby realizing the change of the width of the reflecting plate.

[0040] In the embodiment, the connection between the rotating rod 320 and the second rod 312 is circumferentially spaced apart and provided with a plurality of limiting members, and the second rod 312 is correspondingly provided with a plurality of limiting grooves. After each relative rotation of the rotating rod 320 and the second rod 312 by a certain number of degrees, the limiting members are correspondingly clamped in the limiting grooves, so as to fix the angle between the rotating rod 320 and the second rod 312 during use.

[0041] In the embodiment, the back plate 120 is a second reflecting lens, and the mirror surface of the first reflecting lens 110 faces in the opposite direction. The two extending lenses 400 are double-sided mirrors.

[0042] In the embodiment, the connecting rod 310 and the two rotating rods 320 are provided with heating resistance wires, and the inside of the holding part 200 is provided with a power supply circuit. The heating resistance wires are connected to the power supply circuit.

[0043] Specifically, most of the existing reflecting plates are simple metal plates, glass plates or stainless steel plates, and the surface temperature is the ambient temperature. The temperature in the oral cavity is the body temperature of 37 degrees Celsius. Therefore, if the reflecting plate is directly placed in the oral cavity, the surface of the reflecting plate will quickly accumulate fog and cannot achieve the observation effect. The common solution in clinical practice is to place the reflecting plate in hot water for a period of time before use, and then place it in the oral cavity for observation. However, because the metal material cools down quickly, the surface of the reflecting plate will accumulate fog again after being placed in the mouth for a period of time, affecting the observation effect. By providing heating resistance wires on the rotating rods 320 and the connecting rod 310, and turning on the power supply circuit to preheat before use, the reflecting plate can be effectively prevented from fogging in the oral cavity. The power supply circuit can use a small battery that is easy to replace.

[0044] In the embodiment, the cavity is also provided with a support part, one end of which is installed on the first reflecting lens 110 and the other end is installed on the back plate 120. Specifically, the first reflecting lens 110 and the back plate 120 are installed on the same end of the holding part 200, and the gap between them forms a cavity. Since the first reflecting lens 110 and the back plate 120 are both plate-shaped structures, they are prone to shaking and breaking during use and daily storage. By providing a support part to fix the two, the amplitude of shaking is reduced, and the stability of the reflecting plate is improved.

[0045] It should be noted that the back plate 120 is consistent with the shape of the first reflective lens 110, so the support part can be arranged along the edge of the first reflective lens 110 and the back plate 120, forming a support frame, which can stabilize the two and protect the connecting part 300 inside the cavity.

[0046] In the embodiment, the adjustable oral cavity reflective plate further comprises a protective sleeve, which is sleeved outside the first reflective lens 110 and the back plate 120. Specifically, the use of the reflective plate needs to ensure the cleanliness and smoothness of the mirror surface. Since the mirror surface is prone to scratching and leaving fingerprints, water stains and other marks, by setting the protective sleeve and using disposable medical SMS non-woven fabric and water absorption paper, the mirror surface of the reflective plate can be effectively kept clean and smooth.

[0047] In the embodiment, the first reflective lens 110 and the back plate 120 are movably installed at the same end of the holding part 200, and the connecting part 300 is movably installed on the adjusting button 210 for disassembly and deep disinfection. Specifically, the reflective plate needs to be inserted into the patient's oral cavity and contact the patient's saliva during use, so it should be disinfected or sterilized at a high level after use. However, since the connecting part 300 and the two extension lenses 400 are arranged in the cavity formed between the first reflective lens 110 and the back plate 120 in the device, the existing technology cannot perform deep disinfection and sterilization. The embodiment disassembles the first reflective lens 110, the back plate 120 and the connecting part 300 to separately disinfect and sterilize the above-mentioned parts, so as to ensure the quality of disinfection and sterilization and prevent bacterial infection of the patient in multiple uses.

[0048] In the embodiment, the first reflective lens 110, the second reflective lens and the extension lens 400 are made of thickened glass, stainless steel lens or metal plated film for withstanding high temperature sterilization. Specifically, the reflective plate is a reusable product that needs to go through a series of processes such as cleaning and disinfection after assisting in taking pictures of a patient. High temperature disinfection is generally used for disinfection, so the reflective plate needs to be made of high temperature resistant material to prevent high temperature from affecting the mirror surface of the reflective plate.

[0049] In the embodiment, the holding part 200 is provided with a non-slip sleeve having an opening for accommodating the adjusting button 210. Specifically, the reflective plate is held by a doctor or medical worker by holding the holding part 200 to extend into the patient's oral cavity, and the holding part 200 is the only support point. By setting the non-slip sleeve, the holding of the reflective plate during shooting can be effectively prevented from being unstable, so that the angle and position need to be adjusted again.

[0050] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0051] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that, for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
