[0002] Stomatology is one of the medical disciplines. The main oral diseases include: oral and maxillofacial dermoids, epidermal submandibular space infection, maxillofacial lymphangioma, odontoid malformation, maxillary sinus malignant tumor, jaw ameloblastoma, chronic ethmoid sinusitis, mandibular retrusion, tetracycline teeth, leukoplakia of the tongue and other diseases. Through technology, many periodontal diseases can be completely cured.

[0003] The oral mirror is a commonly used instrument in oral examination. After searching, China Patent Publication No.: discloses an auxiliary lighting structure for oral examination, which includes a grip rod, an extension rod, a oral mirror and an angle adjustment mechanism. The utility model sets an angle adjustment mechanism on the top of the left end of the extension rod. When the oral mirror needs to be adjusted clockwise, the slide cylinder is pushed to the left, so that the connecting rod pushes the slider to slide to the left along the inner side of the slide cavity, and at the same time, the slider pushes the transmission rod to slide to the left along the inner side of the slide groove, so that the transmission rod drives the connecting seat to rotate clockwise along the inner side of the connecting groove through the protrusion, so that the oral mirror rotates synchronously with the connecting seat to adjust the angle. When the oral mirror needs to be adjusted counterclockwise, the slide cylinder is pushed to the right, so that the slider drives the transmission rod to slide to the right, and then the transmission rod drives the oral mirror through the connecting seat to adjust the counterclockwise angle. Medical staff can adjust the oral mirror at any time through the angle adjustment mechanism, and there is no need to take the oral mirror out of the patient's mouth for adjustment, which is convenient for medical staff to better examine the patient's mouth.

[0004] The above-mentioned prior art solution has the following defects.

The left side of the top of the oral mirror grip 1 is movably connected with a rotating block 7. The rotating block 7 can connect the hollow ring 9 and the support ring 8 to the oral mirror grip 1. The surface of the rotating block 7 is fixedly connected with a support ring 8. The support ring 8 can support the hollow ring 9. The surface of the support ring 8 is fixedly connected with a hollow ring 9. The interior of the hollow ring 9 is set to be hollow to facilitate the dispersion of air to multiple defogger ports 10 for jetting. The top of the trachea 6 is connected with the bottom of the hollow ring 9. The inner wall of the hollow ring 9 is provided with a defogger port 10. The defogger port 10 can spray the air inside the hollow ring 9 onto the search mirror 11 for defogging it. The top of the support ring 8 is provided with a search mirror 11, and the top of the search mirror 11 is provided with a clamping assembly, so that the search mirror 11 can be defogged without taking it out of the patient's mouth during oral examination and continue to be used for inspection.

[0033] Reference Figure 1-3The clamping assembly includes a receiving port 12, which can receive a support rod 13 and a clamping plate 14. The receiving port 12 is opened on the inner wall of the hollow ring 9. The receiving port 12 is vertically fixedly connected to the inside of the receiving port 12 with a support rod 13. The support rod 13 can limit the clamping plate 14 so that the clamping plate 14 rotates around the support rod 13. The surface of the support rod 13 is sleeved with a clamping plate 14. The clamping plate 14 can clamp and limit the search mirror 11 to prevent the search mirror 11 from moving out of the hollow ring 9. The clamping plate 14 is located at the top of the search mirror 11; a protective pad 15 is fixedly connected to the bottom of the clamping plate 14, and the protective pad 15 can increase the contact friction between the clamping plate 14 and the search mirror 11 At the same time, it prevents the pressing plate 14 from causing damage to the search mirror 11, and the bottom of the protection pad 15 is in contact with the top of the search mirror 11; the top of the support ring 8 is fixedly connected with a buffer pad 16, which can protect the top of the support ring 8, so that the search mirror 11 is not easily scratched and damaged after being placed thereon, and the top of the buffer pad 16 is in contact with the bottom of the search mirror 11; the inner wall of the hollow ring 9 is inlaid with a protective ring 19, and the protective ring 19 can be placed inside the hollow ring 9 to protect the search mirror 11 and prevent the search mirror 11 from being damaged after collision. The inner wall of the protective ring 19 is in contact with the surface of the search mirror 11, thereby achieving the effect of facilitating the replacement of the search mirror 11 after it is damaged.

[0034] Reference Figure 1-3 A filter pad 17 is provided inside the thread groove 2, and the filter pad 17 can filter the air entering the thread groove 2 so that the air entering the trachea 6 is in a clean state.

[0035] Working principle: When in use, the user rotates the fixing cover 3 to connect the fixing cover 3 and the airbag 4 with the thread groove 2. Then, when the search scope 11 needs to be defogged during the patient's oral examination, the user first squeezes the airbag 4 to allow the air inside the airbag 4 to enter the hollow ring 9 under the transportation of the thread groove 2 and the trachea 6, so that the hollow ring 9 disperses the air transported by the trachea 6 and sprays it onto the search scope 11 through the four defog ports 10, thereby defogging the fog on the search scope 11, so that the search scope 11 can be defogged without taking it out of the patient's mouth during the patient's oral examination. Continue to check the effect of use. When the search mirror 11 is damaged after being bumped and needs to be taken out from the inside of the hollow ring 9 for replacement, the clamping plate 14 is rotated to make the clamping plate 14 drive the buffer pad 16 to rotate to the inside of the storage port 12 around the support rod 13, so as to release the clamping fixation on the top of the search mirror 11. Then the search mirror 11 can be taken out from the inside of the hollow ring 9. When installing a new search mirror 11, the above disassembly steps can be reversed to install the search mirror 11 into the inside of the hollow ring 9, thereby achieving the effect of facilitating the replacement of the search mirror 11 after it is damaged.
