Description

Technical Field

[0001] The utility model relates to the technical field of medical tongue depressors, in particular to an adjustable tongue depressor device. Background Art

[0002] Oral cancer is a cancer that occurs in the oral cavity and its accessory tissues. The most common sites for cancer are the tongue, followed by the gums, cheeks, palate, lips, and floor of the mouth. There are many treatments for oral cancer, of which surgery and radiotherapy are the most common. Depending on the severity of the patient's disease, radiotherapy can be used as the main treatment or auxiliary treatment. Radiotherapy does not require anesthesia, does not cause surgical incisions, and does not remove tissue, so it is popular with patients.

[0003] In clinical practice, when radiotherapy is performed on the oral cavity, the upper palate and tongue need to be separated. The current solution is to stack multiple ordinary tongue depressors together according to the distance between the patient's upper palate and tongue, arrange them in a trapezoidal shape, and then wrap them with medical tape to fix them. When in use, put this homemade tongue depressor into the patient's mouth and hold it in your mouth to separate the upper palate and tongue; but the problem with this method is that the homemade tongue depressor needs to be made temporarily each time, and the outer packaging of multiple ordinary tongue depressors needs to be torn off, the tongue depressors need to be broken and placed in place, and then wrapped with medical tape to fix them; since they need to be made before each radiotherapy, it is more troublesome and reduces the efficiency of radiotherapy treatment.

[0004] Chinese patent document CN205649744U discloses a radiotherapy mouthpiece, including a tongue depressor with a flat top surface and an arc bottom surface in a semi-cylindrical shape, a bite limiter is provided at the left end of the top surface of the tongue depressor, a plurality of limiter steps are evenly arranged on the upper surface of the bite limiter, and a plurality of bite grooves are provided on the bottom surface of the tongue depressor corresponding to the limiter steps. When the radiotherapy mouthpiece in the patent document is used, the radiotherapy mouthpiece is placed in the patient's mouth by holding the handle, and the patient's upper teeth are bitten on the limiter steps of the appropriate bite limiter according to the size of the patient's mouth, and the patient's lower teeth are bitten on the corresponding bite grooves, the mouthpiece is extended into the patient's mouth, and the arc bottom surface of the tongue depressor presses the tongue, so that the opening and fixing of the tongue are very good, and sliding and shaking will not occur, which is conducive to assisting radiotherapy treatment.

[0005] The problem with the technical solution in the above-mentioned document is that the height of the limit step set on the upper surface of the bite limit part is fixed. When the distance between the upper palate and the tongue needs to be adjusted, the patient needs to re-select a suitable bite position for bite, which is very inconvenient to adjust and will prolong the radiotherapy time. When the patient feels uncomfortable, the height of the limit step cannot be lowered in the first time, which can easily cause harm to the patient and increase the patient's pain.

[0006] Therefore, how to design an adjustable tongue depressor device that can adjust the distance between the upper palate and the tongue during radiotherapy without delaying the radiotherapy time, and can adjust the appropriate height according to the patient's needs, and can also reduce the distance between the upper palate and the tongue at any time, is a technical problem that has not yet been solved in the prior art.
