Oral cavity detection device with replaceable detection head

The present invention relates to an oral cavity detection device, in particular to an oral cavity detection device with a replaceable detection head that achieves the effect of easy replacement of the detection head.

The health of the oral cavity has a great impact on people's daily life, and the oral cavity is the only tissue in the body that exposes some internal organs, such as teeth, periodontal, tongue, etc. Therefore, it is very important to check the oral cavity frequently. With the development of medicine, in addition to observing the health of the teeth, the organs in the oral cavity can also be used to predict whether the body has disease or not. It is more and more widely used. There are many types of hoarded dental plaque, and ordinary people have limited visual observation results. If there is no relevant medical-grade oral inspection device, if you want to understand the condition of the oral cavity, you can only seek a dentist to know the condition of the oral cavity through professional diagnosis. Until now So far, dentists have mainly performed visual inspections. With the doctor’s professional skills, the diagnosis of oral conditions will vary due to many factors, and the distribution of dental plaque, caries and calculus cannot be clearly pointed out, which makes it impossible to treat and prevent in time. The efficacy of decay must wait until the dental caries is under obvious visual and tactile detection or when pain occurs. Often the disease has reached an advanced stage. If it is not treated immediately, it may cause tooth defect. Although there are large-scale medical-grade dental inspection devices available in the medical field that can detect plaque and calculus on the teeth, the inspection costs are often quite expensive, which leads to a certain degree of pressure.
