Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable detachable assembled dental mirror. Background Art

[0002] Dental mirrors are dental instruments. Their main purpose is to reflect images of areas that cannot be directly seen. They can be used to focus light on the inspection area to increase local illumination. When necessary, a concave mouth mirror can be used to magnify the image. They can also be used to pull or press soft tissues such as lips, cheeks and tongue. After use, the surface of existing dental mirrors will be contaminated with bacteria from the patient's mouth and need to be cleaned and disinfected. Since the working environment of the dental mirror body is located inside the patient's mouth, the dental mirror body will be contaminated with more bacteria when in use. When cleaning and disinfecting the dental mirror body, there are more steps and it takes a long time. The working environment of the handle is located inside the patient's mouth. The outside of the cavity makes the handle less likely to be contaminated with bacteria, and the steps are relatively few and the time is relatively short when cleaning and disinfecting the handle; therefore, the dental mirror body and the handle are cleaned and disinfected separately, which can effectively improve the cleaning efficiency; the existing dental mirror body and the handle are usually fixed by a threaded connection, but in order to reduce the friction between the surface of the dental mirror body and the patient's oral skin and improve the comfort of the dental mirror body when used, the surface of the dental mirror body is usually smoother, which reduces the friction between the medical staff's fingers and the dental mirror body, making it more difficult for the medical staff to twist the dental mirror body.
