Description

Technical Field

[0001] The utility model relates to the technical field of skin lesion sampling, in particular to a blade structure used for skin lesion sampling. Background Art

[0002] Fungal microscopy is a common method for skin fungal examination, which is to use a skin lesion sampling knife to scrape a little dandruff on the surface of the patient's skin lesions and observe it under a microscope. Due to the different skin lesions of patients, the requirements for the scraper used in skin lesion sampling are also different. Commonly used skin lesion sampling knives include a handle and a blade that is plugged into the handle. Before taking samples from different skin lesions, doctors will select suitable blades to install on the handle, and disinfect the blades and handles after taking samples. Regarding the above-mentioned related technologies, when doctors scrape skin lesions, the dandruff on the surface of the patient's skin is easily scraped by the skin lesion sampling knife and floats in the air, making it very easy for pathogens to attach to the dandruff and spread to others through the air.
