Description

opener

technical field

The utility model relates to an opening device in dental treatment, in particular to a multifunctional opening device.

Background technique

At present, most clinicians in the stomatology department of the hospital require the patient to open the mouth for a long time when examining or treating the patient, which can easily cause facial muscle fatigue of the patient; secretions and cleaning fluid (saliva in the oral cavity is mainly secreted by the parotid gland and sublingual gland); and because the patient's tongue is easy to move, the doctor's operating vision is not good for drilling and filling teeth. Therefore, for the convenience of treatment, stomatologists often use gags to help patients open their lips. The mouth gag is usually composed of lip insertion grooves and an elastic frame supported and connected to the two lip insertion grooves. During use, the elastic frame is squeezed so that the insertion grooves on both sides are placed between the lips to force the patient's mouth to open. Although the existing gags are relatively simple and convenient to use, for stomatology, they need to be in frequent contact with blood and saliva during the operation, and these may directly or indirectly lead to cross-infection. Therefore, there is an urgent need for a kind of oral appliance that can make the oral cavity wet and convenient for the doctor to operate during the oral cavity treatment process.

After checking, many existing mouth gags in China only have one of the supplementary functions, and there is no gag with multiple functions such as supporting the lips, sucking saliva and preventing moisture, and blocking the tongue.

Similar products have the patent No. 200810067700.7 Gao Yongbo et al. "A mouth gag with a saliva suction device". The gag designed is to be provided with a saliva suction tube on a hollow elastic frame, and the end of the saliva suction tube is formed by a filter cap head , although it plays a role of partial moisture isolation and can absorb part of the saliva secreted by the sublingual gland, it cannot achieve the effect of complete moisture isolation. Another patent number is 200920226341.5 Mr. Huang Diyan's "Multipurpose Oral Opener". The opener designed has no saliva suction structure, and is a pincer structure connected by hinges. The structure is complex, the operation is cumbersome, and the promotion value is average; there is also a patent No. 200920254768.6 Mr. Guo Feng's "Tongue Depressor", it simply considers that the tongue is pressed down to facilitate the doctor's operation, and it does not take into account that it often causes poor taste, nausea and discomfort to the user during the clinical process Wait for performance.

Internationally, in light-curing restoration of teeth, rubber dams are mostly used to isolate the teeth, so as to prevent the saliva in the mouth from flowing into the dentist's operating area, resulting in contamination of the operated teeth by saliva or blood, resulting in filling failure. However, the cost of rubber dam materials is high, and it is difficult to popularize in small and medium-sized hospitals and outpatient clinics; the operation is difficult and inconvenient to use; for people who have the habit of mouth breathing, it is necessary to cut out holes on the rubber cloth to relieve shortness of breath.
