Description

  The present invention relates to a dental endoscope holding device, and more particularly, to a dental endoscope holding device for holding a fiberscope of a dental endoscope to teeth.

  When using instrument devices and treatment jigs in dental treatment, the surgeon directly observes the area of the oral cavity to be treated with the naked eye, and observes the unobservable parts using a dental mirror. It is common to do. However, when using the dental mirror, it is necessary to operate the instrument device with the other hand while holding the dental mirror with one hand. For this reason, the operator is required to perform a complicated operation and to acquire experience for an accurate operation.

  In addition, in order to enhance the accuracy of dental treatment, a microscope is used to magnify the treatment site by using a microscope.
