Description

Technical Field

[0001] The present application relates to the technical field of oral examination, and in particular to an oral examination auxiliary device. Background Art

[0002] Oral examination is an important part of oral care. It helps doctors understand the patient's oral condition and provides a basis for diagnosis and treatment. Oral examination includes local examination of the teeth, gums, oral mucosa, etc. Oral examination auxiliary equipment is needed during the cavity examination. Nowadays, the more commonly used oral examination auxiliary equipment is the oral examination mirror. The oral examination mirrors currently on the market generally have a handle made of one-time injection molding of plastic parts and a mirror fixed at the end of the handle. When the doctor needs to examine the patient's mouth, the mirror fixed at the end of the handle cannot rotate alone, but can only rotate with the movement of the handle, which can easily cause the handle to block part of the patient's mouth, affecting part of the doctor's field of vision, causing the doctor's examination to take more time to complete.

[0003] In response to the above problems, a patent document with authorization announcement number CN217090676U announces an adjustable oral examination auxiliary device, which belongs to the field of oral examination technology. An operating cavity is provided inside the handle, and the operating cavity is provided with a limit ring. A movable rod is inserted in the operating cavity, and a convex strip is provided on the movable rod. The convex strip is connected to the limit ring through a spring. One end of the movable rod extends out of the operating cavity, and the other end passes through and extends out of the limit ring. A threaded hole is provided on the end of the movable rod that passes through and extends out of the bottom of the operating cavity, and the end of the movable rod that passes through and extends out of the limit ring is fixedly connected to a magnetic base, a limit bolt is threadedly connected to the handle, and a movable joint is provided on the handle near the magnetic base, a rotating rod is connected to the movable joint, and a mouth mirror is fixedly connected to the rotating rod, which solves the problem that when the doctor needs to examine the patient's mouth, the mirror arranged at the end of the handle cannot be rotated alone, but can only rotate with the movement of the handle, which easily causes the handle to block part of the patient's mouth and affect part of the doctor's field of vision.

[0004] In actual use, it is found that the above-mentioned related schemes still have at least the following shortcomings: when using oral examination auxiliary equipment to examine the inside of the oral cavity, the patient can only control the opening of the mouth by himself, and it does not have the function of effectively supporting the mouth. When the doctor needs to spend a long time to conduct a comprehensive examination of the patient's oral cavity, the patient will feel tired if he opens his mouth for a long time by himself, and will also close his mouth unconsciously, which will affect the doctor's smooth examination of the patient's oral cavity. Therefore, we propose an oral examination auxiliary equipment to solve the above problems. Utility Model Content

The two limiting blocks are respectively slidably installed in the corresponding limiting grooves to limit the sliding stroke of the telescopic column 12.

[0029] Through the above structure, when the oral examination auxiliary device provided by the present application is used, when the patient opens his mouth to examine the oral cavity, by letting part of the patient's upper teeth bite on the upper tooth pad 13 and letting part of the patient's lower teeth bite on the lower tooth pad 9, the patient can be effectively prevented from closing his mouth unconsciously, and the fatigue caused by the patient's mouth being open for a long time can be reduced, thereby ensuring that the doctor can smoothly examine the oral cavity, and it is easy to adjust the distance between the lower tooth pad 9 and the upper tooth pad 13, so as to change the size of the patient's mouth opening, so that the patient's mouth opening can be kept appropriate, which is more conducive to the doctor's examination of the patient's oral cavity. During the specific operation, let the patient open his mouth wide and put the mouth mirror 4 , the arc rod 3 and the left end of the handle 1 are inserted into the patient's mouth, and part of the patient's upper teeth are bitten on the upper tooth pad 13, and part of the patient's lower teeth are bitten on the lower tooth pad 9. The medical staff uses two fingers to pinch the handle 5 to pull, slide or rotate the movable rod 2, that is, the position and angle of the mouth mirror 4 can be flexibly adjusted, so that the valve can be conveniently used for a comprehensive inspection of the oral cavity. When the patient's mouth is opened for inspection, by making part of the patient's upper teeth bite on the upper tooth pad 13 and part of the patient's lower teeth bite on the lower tooth pad 9, the patient can be effectively prevented from closing his mouth unconsciously, and the fatigue caused by the patient's mouth being open for a long time can be reduced, thereby ensuring that the doctor can smoothly inspect the oral cavity;

[0030] During the oral examination of the patient, when it is necessary to change the degree of opening of the patient's mouth, the knob 20 is turned clockwise, and the knob 20 drives the rotating shaft 18 and the main bevel gear 19 to rotate clockwise, and the main bevel gear 19 drives the secondary bevel gear 17 and the screw rod 15 to rotate, so that the telescopic column 12 gradually slides out of the slide groove 11, and the telescopic column 12 drives the upper tooth pad 13 to move. At this time, the distance between the lower tooth pad 9 and the upper tooth pad 13 gradually increases, and the upper tooth pad 13 will apply a force to the upper teeth to move upward. At this time, the degree of opening of the mouth will gradually increase. Similarly, by turning the knob 20 counterclockwise, the distance between the lower tooth pad 9 and the upper tooth pad 13 can be gradually reduced, and the degree of opening of the mouth will gradually decrease, which is convenient for adjusting the distance between the lower tooth pad 9 and the upper tooth pad 13. After the distance between the lower tooth pad 9 and the upper tooth pad 13 is adjusted appropriately according to needs, that is, when the patient's mouth is opened to an appropriate size, the doctor can more smoothly examine the oral work.
