Description

Visual disinfection cleaning device for oral treatment

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a visual disinfection and cleaning device for oral treatment.

Background

Pulpitis is one of the most common oral diseases, and at the onset of pulpitis, peripheral nociceptors and central neurons of the pulp are in a hyperalgesic state. The stimulation threshold of the pain-sensitized peripheral receptors is reduced, the excitability is increased, the central neurons also have changes such as expansion of receptive fields, and the like, and the patients show symptoms of cold and hot stimulation pain, spontaneous pain and diffuse pain.

The most important cause of inflammation of the dental pulp is infection, and when hard tissues of the tooth are damaged due to various reasons, bacteria can invade and infect the dental pulp. Among them, caries is the most common cause of loss of hard tissues of teeth, and other causes include tooth defects caused by abnormal development of teeth, broken dental crowns and exposed dental pulp caused by accidents, and direct damage to dental pulp. Also secondary to pulpitis is periapical disease, an inflammatory disease that occurs in periapical tissues. Bacteria and toxins thereof in dental pulp, pulp necrosis products, etc. act on periapical tissues through apical foramen, resulting in periapical inflammatory lesions. In addition, in severe periodontal disease, the periodontal pocket reaches the apical part, and bacteria can enter the pulp cavity from the apical foramen or some tiny branches of the root to cause pulpal inflammation.

In the prior art, a plurality of medicines for treating pulpitis and periapical disease comprise plaster, powder, lotion and the like, a specific medicine applicator is used for assisting medicine application aiming at plaster and powdered medicines, but before medicine application, proper disinfection and cleaning are still needed to be carried out on diseased teeth, so that the medicines can exert better curative effect, and a conventional syringe is usually adopted for flushing and treating flushing liquid, but the flushing is not thorough enough, and dead corners exist easily. The patent with publication number CN109419560A in the prior art discloses a spray head for a visual tooth flusher and a visual tooth flusher, wherein a water outlet of the spray head is in a visual field of an observation system of an oral cavity observation instrument. The pressure container comprises a pressurizing device, a shell and a fluid containing space. The water pressure in the pressure container can be increased through the pressurizing device, the control switch is turned on, water is sprayed out of the spray head of the spray gun, teeth or oral cavity cleaning can be carried out under direct vision, and photographing and shooting are carried out in the cleaning process in real time. Even with such a visible irrigator, the inside of dental caries pulpitis cannot be deeply sterilized and disinfected, greatly reducing the curative effect of the medicine.
