In 2024, the Hospital Management Institute of the National Health Commission issued a letter on the implementation plan of "Strengthening perioperative infection prevention and control and ensuring surgical quality and safety", which clearly requires: If hair needs to be removed, use non-skin-damaging methods and avoid using blades to shave hair.

[0003] However, the skin preparation kits currently used in clinical practice generally include skin preparation knives, sponges, paper towels, and talcum powder. Since the skin preparation kit does not contain a padding sheet, hair generated during the shaving and skin preparation process is very easy to stain the bed sheets and is not easy to clean, causing discomfort to the patient, and the umbilicus cannot be cleaned, seriously affecting the skin preparation and shaving experience; at the same time, the blade of the skin preparation knife used for skin preparation is sharp, and it is in direct contact with the skin during the skin preparation process, which is very easy to cause tiny cuts and scratches, thereby destroying the skin's barrier against external microorganisms and increasing the risk of surgical incision infection. At the same time, it is necessary to wait for the wound to heal before surgery can be performed, causing delays in surgery. In addition, the gripping operating end and the shaving end of the existing skin preparation shaving scissors are generally fixed at a fixed angle. During the shaving and skin preparation process in some narrow skin areas, the operating space of the operating end is limited, which seriously affects the skin preparation operation, resulting in insufficient hair removal length, excessive reserved length, and accidental injury to the skin.
