Description

Technical Field

[0001] The utility model relates to the technical field of stomatology, in particular to an oral expansion auxiliary fixing device. Background Art

[0002] Stomatology is one of the medical disciplines. The main oral diseases include: oral and maxillofacial dermatitis, epidermal submandibular space infection, maxillofacial lymphangioma, odontoid malformation, maxillary sinus malignant tumor, jaw ameloblastoma, chronic ethmoid sinusitis, mandibular retraction, tetracycline teeth, leukoplakia of the tongue and other diseases. Through technology, many periodontal diseases can be completely cured. The development of tissue bioengineering technology such as guided tissue regeneration technology, gene technology, and implant dentures has brought exciting hope for the regeneration of diseased teeth. However, the treatment of periodontal disease must be a sequence of treatment. In the treatment process, formulating a detailed and effective treatment plan, the doctor's meticulous and exquisite treatment, and the patient's active cooperation are the keys to successful treatment. When the doctor diagnoses and treats the patient's mouth, he needs to use a mouth opener to open the patient's mouth to facilitate the doctor's diagnosis and treatment.

[0003] Existing mouth openers are usually of fixed specifications. Therefore, when the mouth openers are used, the size of the mouth cannot be adjusted according to the size of the patient's mouth. As a result, the patient's mouth may be stretched too much, causing discomfort to the patient. It may also be impossible to fully stretch the patient's mouth, making it inconvenient for doctors to diagnose and treat. For this reason, we propose an oral expansion auxiliary fixation device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 , an oral expansion auxiliary fixing device, comprising a main frame 1, an upper support seat 2 and a lower support seat 3 are provided on one side of the main frame 1, and a soft cushion 6 is fixed on the inner side of the upper support seat 2 and the lower support seat 3, a connecting rod 4 is fixed on one side of the upper support seat 2, and a push plate 7 is fixed on one side of the connecting rod 4, and the connecting rod 4 slides on the inner side of the main frame 1, and a double-fork connecting frame 5 is fixed on one side of the lower support seat 3, and limit plates 19 are fixed on both ends of the double-fork connecting frame 5, and an adjustable connecting component is provided between the double-fork connecting frame 5 and the main frame 1, and the adjustable connecting component includes two fixed columns 16, and the fixed columns 16 are fixed on the lower side of the main frame 1, and one side of the fixed columns 16 is provided with a through hole, and the double-fork connecting frame 5 slides on the inner side of the through hole, and one side of the fixed column 16 is provided with a threaded hole, which is connected to the through hole, and the inner side of the threaded hole is connected by a thread A threaded column 17 is provided, one end of the threaded column 17 is in contact with the double-fork connecting frame 5, and a twisting piece 18 is fixedly provided at one end of the threaded column 17. During use, when the patient's mouth needs to be opened, it is necessary to first adjust the staggered distance between the upper support seat 2 and the lower support seat 3 (the distance between the upper support seat 2 and the lower support seat 3 in the horizontal plane projection) according to the position of the patient's upper jaw and lower jaw. When adjusting the staggered distance between the upper support seat 2 and the lower support seat 3, it is necessary to first rotate the threaded column 17 by twisting the piece 18 to loosen the threaded column 17, and then slide and adjust the double-fork connecting frame 5. At this time, the double-fork connecting frame 5 will slide on the inner side of the through hole, so that the staggered distance between the upper support seat 2 and the lower support seat 3 can be adjusted. After the adjustment is completed, it is necessary to tighten the threaded column 17 by twisting the piece 18, and the double-fork connecting frame 5 and the lower support seat 3 can be locked, so that two-way adjustment can be achieved;

[0022] A quick adjustment and release connection assembly is provided between the main frame 1 and the connecting rod 4, and the quick adjustment and release connection assembly includes a connecting cover 8, a sliding plate 9 is slidably provided on the inner side of the connecting cover 8, a guide rod 10 and a handle 11 are fixed in sequence on one side of the sliding plate 9, a through hole is provided on one side of the connecting cover 8, the guide rod 10 slides on the inner side of the through hole, a spring 12 is fixed between one side of the sliding plate 9 and the inner side of the connecting cover 8, a mounting groove is provided on one side of the connecting rod 4, a clamping plate 13 is fixedly provided on the inner side of the mounting groove, a plurality of beveled grooves 14 are provided on one side of the clamping plate 13, and a plurality of beveled blocks 15 are fixedly provided on the other side of the sliding plate 9, and the beveled blocks 15 are detachable from the inner side of the beveled grooves 14. When in use, when the patient's mouth needs to be opened, the patient's upper teeth need to be placed in the upper support seat 2 first, and then the patient's lower teeth need to be placed in the lower support seat 3. Then, hold the main frame 1 by hand, and then push the connecting rod 4 upwards through the push plate 7 to open the patient's mouth. The distance between the upper support seat 2 and the lower support seat 3 in the vertical direction can be adjusted according to the size of the patient's mouth, so as to meet various usage requirements. When pushing the connecting rod 4 upwards, since both the bevel block 15 and the bevel slot 14 have bevels, the bevel block 15 will automatically disengage from one bevel slot 14 and then be inserted into the other bevel slot 14. There is no need to pull the handle 11, and the connecting rod 4 can also be pushed upwards, so that quick adjustment can be made, which is convenient for use. When the diagnosis and treatment are completed and the opening needs to be released, only the handle 11 needs to be pulled to make the bevel block 15 disengage from the bevel slot 14, so that the connecting rod 4 can be moved downward, and quick release can be made, which is convenient for removal and use.
