Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a dental oral examination device. Background Art

[0002] The oral cavity, as the starting part of the digestive tract, contains important organs such as teeth and tongue. Once a dental disease occurs, doctors need to conduct a comprehensive examination of the patient's oral cavity and teeth. During the examination process, an oral examination device is an essential tool. Such a device usually consists of a handle and a lens. The lens can help doctors observe the internal structure of the oral cavity and the details of the teeth more clearly. By using this device, doctors can, after the examination, make a preliminary diagnosis of the patient's oral diseases and formulate a treatment plan.

[0003] Currently, a Chinese utility model patent application with a publication date of June 22, 2021, and a publication number of CN 213488714U provides an oral mirror for dental examination, including a metal handle, a frame, a lens, a thin sheet separator, and a perforation. A frame is provided at the bent section on the front side of the metal handle. The lens is inlaid in the frame. A thin sheet separator made of a metal plate is provided in the middle of the frame. An MCH type heating sheet is glued to the rear surface of the thin sheet separator through a polyimide tape. After the heating process, the lens installed on the other side of the separator will be heated up, and due to its small size, the temperature will quickly drop to a non-skin-burning level after power-off, but the residual heat temperature will definitely be higher than the temperature of the exhaled gas from the human oral cavity. When the oral mirror is inserted into the patient's oral cavity for examination, since the temperature of the lens is higher than the temperature of the exhaled gas from the oral cavity, according to the existing liquefaction phenomenon, the lens will not form fog on the mirror surface due to the exhaled gas, thus ensuring the normal use of the lens in the oral cavity for a long time.

[0004] In the related art, for the oral mirror used in dental examination, it is impossible to ensure that the patient's oral cavity is always in an open state during the use of the oral mirror. The examination of the oral mirror depends on the patient maintaining a stable open-mouth state so that doctors can clearly observe the internal structure of the oral cavity. If the patient cannot keep the mouth open continuously, doctors may not be able to observe the teeth, gums, tongue, buccal mucosa and other parts completely, resulting in an incomplete examination.

[0005] Therefore, it is necessary to provide a dental oral examination device to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Based on this, in order to improve the technical problem in the related art that it is impossible to ensure that the patient's mouth is always open during the use of the oral mirror, resulting in incomplete examination, the embodiments of the present application provide the following solutions.

[0023] Please refer to Figures 1 to 4 FIG. 1 together. An embodiment of the present application provides a dental oral examination device, which includes an annular bracket 1, a rotating ball 11, an oral mirror bracket 12, and an expansion assembly 2. The rotating ball 11 is arranged on the annular bracket 1. A rotating hole 17 is provided on the rotating ball 11. The oral mirror bracket 12 passes through the rotating hole 17 and is arranged on the rotating ball 11. The expansion assembly 2 is arranged on the annular bracket 1.

[0024] In some embodiments, please refer to Figures 1 to 2, the expansion component 2 includes a fixed seat 21, a rotating shaft 22, a support block 23 and an extension member 24. The fixed seat 21 is arranged on the circular ring bracket 1, the rotating shaft 22 is rotatably arranged on the fixed seat 21, the extension member 24 is arranged on the rotating shaft 22, and the support block 23 is arranged at one end of the extension member 24 away from the rotating shaft 22. The extension member 24 includes a fixed plate 241, an extension plate 242, a spring 245 and a button 246. The fixed plate 241 is arranged on the rotating shaft 22, the extension plate 242 is movably arranged on the fixed plate 241. A limiting hole 243 is formed on the fixed plate 241, a connecting groove 244 is formed on the extension plate 242, the spring 245 is arranged in the connecting groove 244, the button 246 is arranged at one end of the spring 245 away from the connecting groove 244, and the button 246 is movably arranged in the limiting hole 243. A biting rubber pad 4 is arranged on the support block 23.

[0025] With such a setting, during the process of oral examination required by the patient, the medical staff rotates the rotating shaft 22 on the fixed seat 21 to rotate the extension member 24 to a position perpendicular to the oral mirror bracket 12. Then, by having the patient's teeth abut against the occlusal rubber pad 4 on the support block 23, pressing the button 246 on the extension plate 242, the spring 245 is pressed by the button 246 to reduce the restriction of the limiting hole 243 on the button 246, pulling the extension plate 242 to adjust the position of the extension plate 242 on the fixed plate 241. When in the appropriate position, the button 246 is pressed by the spring 245 to make the button 246 pass through the limiting hole 243, thereby fixing the extension plate 242, thus assisting the patient to open the mouth. When the examination device is not needed, the rotating shaft 22 on the fixed seat 21 is rotated to drive the extension member 24 and the support block 23 on the extension member 24 to be parallel to the oral mirror bracket 12, thus facilitating storage. In this way, when the patient needs to keep the mouth open for a long time during oral examination, it is easy to feel fatigued and uncomfortable. This device supports the patient's oral cavity through the occlusal rubber pad 4, helps the patient maintain a comfortable mouth-opening state, reduces the muscle burden. The device can be adjusted in terms of the telescopic adjustment of the extension plate 242 to adapt to the oral cavity sizes and examination requirements of different patients, improving the patient's comfort. The device can stably fix the patient's oral cavity in a suitable position, preventing the examination from being interrupted or inaccurate due to unstable mouth-opening of the patient. The medical staff can perform examination operations more conveniently, such as using tools like oral mirrors and probes, without frequently adjusting the patient's mouth-opening state. The device can adjust the position of the extension member 24, facilitating the medical staff to observe the internal situation of the oral cavity from different angles to ensure the comprehensiveness of the examination. The position adjustment can be completed by pressing the button 246 and pulling the extension plate 242, and the operation process is simple and fast. When not in use, the extension member 24 can be rotated to a position parallel to the oral mirror bracket 12, saving space and facilitating storage and placement. The adjustable design of the device reduces the time for the medical staff to adjust the patient's oral cavity position during the examination, improving work efficiency. The patient is more likely to relax under comfortable support, reducing involuntary movements caused by tension, thus improving the smoothness of the examination.

[0026] In some embodiments, please also refer to Figures 3 to 4 , the circular ring bracket 1 is provided with an annular inner wall in the shape of a spherical surface. The spherical annular inner wall of the circular ring bracket 1 and the rotating sphere 11 are circles with the same diameter. The circular ring bracket 1 is used to limit the rotating sphere 11 and at the same time facilitate the rotation of the rotating sphere 11 to drive the oral mirror bracket 12 to adjust the angle. A connecting nut 3 is rotatably arranged on the circular ring bracket 1 for restricting the rotation of the rotating sphere 11. A hand-held handle 16 is arranged at one end of the oral mirror bracket 12 away from the lens 13. A lens 13 is arranged at one end of the oral mirror bracket 12, and an LED lamp 14 is arranged on the lens 13. A heating sheet 15 is arranged on the lens 13.

[0027] With such a setting, during the examination, medical staff can drive the rotating ball 11 on the circular support 1 to rotate by turning the hand-held handle 16 on the oral mirror support 12, and observe the dental condition in the patient's oral cavity through the lens 13. At the same time, the LED lamp 14 can assist in the observation. A heating sheet 15 is provided on the lens 13 to prevent the lens 13 from fogging up when it enters the patient's oral cavity in cold weather. At the same time, the fixing nut facilitates the situation where medical staff may need to release both hands from the hand-held handle 16 on the oral mirror support 12 during the patient's use. By turning the fixing nut, the rotation of the rotating ball 11 is fixed, and the oral mirror support 12 is fixed, thereby assisting the patient in the examination and treatment. In this way, medical staff can drive the rotating ball 11 by turning the hand-held handle 16 to easily adjust the angle and direction of the oral mirror, so as to comprehensively observe various parts in the patient's oral cavity, including teeth, gums, tongue, cheeks, etc. This flexibility helps to discover problems in hidden parts, improve the accuracy and comprehensiveness of the examination. During the examination, medical staff can adjust the position of the oral mirror at any time according to needs, without frequently moving the patient or readjusting the patient's posture, thereby improving the examination efficiency. The LED lamp 14 can provide sufficient and uniform light source to help medical staff clearly observe the details inside the oral cavity in case of insufficient light, which is particularly important for examining problems such as dental caries, gingival inflammation, oral ulcers, etc., especially in the posterior part or hidden parts of the oral cavity. The heating sheet 15 on the lens 13 can effectively prevent the lens 13 from fogging up when it enters the patient's oral cavity in cold weather. This design ensures that the lens 13 always remains clear, avoiding blurred vision caused by fog, thereby improving the reliability and accuracy of the examination. By turning the fixing nut, medical staff can fix the rotation of the rotating ball 11, thus freeing both hands. This enables medical staff to still keep the oral mirror stable when they need to perform other operations such as using instruments and recording examination results, without the need for a special person to support it. This design is particularly suitable for single-person operation, reducing the dependence on auxiliary personnel, improving work efficiency, and at the same time reducing the risk of cross-infection caused by multi-person operation. The flexible adjustment of the oral mirror can avoid excessive compression or discomfort to the patient's oral tissues, improving the patient's comfort. The clear examination field of view and flexible operation method can let the patient feel the professionalism of the medical staff, enhance the patient's trust in the examination process, and thus better cooperate with the examination.

[0028] The implementation principle of a dental oral examination device in an embodiment of the present application is as follows: During the process of a patient needing an oral examination, medical staff rotate the rotating shaft 22 rotating on the fixed seat 21 to rotate the extension member 24 to a position perpendicular to the oral mirror bracket 12. Then, the patient's teeth are made to abut against the occlusal rubber pad 4 on the support block 23. By pressing the button 246 on the extension plate 242, the spring 245 is pressed by the button 246, reducing the restriction of the limiting hole 243 on the button 246, pulling the extension plate 242, and adjusting the position of the extension plate 242 on the fixed plate 241. When in a suitable position, the button 246 is pressed by the spring 245, enabling the button 246 to pass through the limiting hole 243, thereby fixing the extension plate 242, and thus assisting the patient to open their mouth. During the examination process, medical staff drive the rotating ball 11 on the circular ring bracket 1 to rotate by rotating the hand-held handle 16 on the oral mirror bracket 12, observe the dental condition in the patient's oral cavity through the lens 13. At the same time, the LED lamp 14 can assist in the observation. A heating sheet 15 is provided on the lens 13 to prevent fogging when the lens 13 enters the patient's oral cavity in cold weather. At the same time, the fixing nut facilitates that during the patient's use, medical staff may need to release their hands from the hand-held handle 16 on the oral mirror bracket 12. By rotating the fixing nut, the rotation of the rotating ball 11 is fixed, and the oral mirror bracket 12 is fixed, thereby assisting the patient in examination and treatment. When the examination device is not needed, the rotating shaft 22 on the fixed seat 21 is rotated to drive the extension member 24 and the support block 23 on the extension member 24 to be parallel to the oral mirror bracket 12, thus facilitating storage.

[0029] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the protection scope of the present application.
