Description
technical field [0001] The invention relates to the field of medical devices, in particular to a skin scraper for preventing secondary damage. Background technique [0002] Skin scraping is widely used in dermatology. The existing skin scraping methods usually use medical staff to slowly grind and scrape the patient's skin surface with a scraper. This method requires medical staff to press the skin for a long time Positioning, and scraping through the reciprocating movement of the arm, this scraping method requires the medical staff to hang their arms in the air for a long time. There is a deviation in the scraping, which will cause secondary damage to the patient. [0003] In order to liberate the medical staff, hospitals now generally use skin scrapers to clean the skin, but most of these scrapers use direct scraping. This scraping method is quick and can easily cause secondary damage to the patient's skin. Moreover, due to the use of equipment for scraping, the scraper ...
