Description

Skin mirror accessory suitable for mucous membrane position

Technical Field

The utility model relates to a skin mirror annex suitable for mucous membrane position.

Background

Dermatological diseases, the observation of lesion morphology and fine structure is one of the main methods for diagnosing diseases. However, the ability to visually identify the microstructure of a lesion site is sometimes insufficient to meet the diagnostic requirements. Pathological examinations are also deficient in diagnosis because of their invasive and non-immediate nature. The appearance of the dermatoscope fills up the imperfect part between the two, so that the observation can be finished noninvasively in real time, and the focus part is enlarged from multiple angles. The dermatoscope becomes a bridge between the clinical gross structure and the histopathological microstructure.

The application of a dermoscope to body surface skin has not been problematic. However, the existing dermatoscope is limited by the contact type examination and the size of the lens, so the examination of mucous membrane parts such as oral cavity, vagina, anal canal and the like cannot be effectively carried out. The main problem is that because the skin mirror can only observe the part vertical to the lens, the operation space and angle are both one of the main problems for checking, and the part (most part is the mucous membrane part in the body cavity) with insufficient operation space and unsuitable angle can not be observed sufficiently. The precision and cost of the existing optical fiber cannot meet the requirements of a skin mirror. There is also a problem of wrinkles in the observation site which is a limitation of current dermoscopy. The clinical examination of these specific sites is now mainly by means of visual observation or pathological biopsy. Both of these approaches have the disadvantage that microscopic structures are not visible by visual inspection, and the pathological biopsy can be traumatic to the patient.
