[0001] The utility model relates to the technical field of medical devices, in particular to a medical skin preparation device before urinary disease surgery. Background Art

[0002] Skin preparation refers to the surgical preparation of shaving the hair at the corresponding part of the operation and cleaning the body surface. It is the work of cleaning the surgical area before the operation for patients who are going to undergo surgery. It is not as simple as removing body hair, but also includes skin cleaning. Sometimes, skin iodine scrubbing is required before the operation. At present, skin preparation before surgery is generally divided into two categories: shaving skin preparation and non-shaving skin preparation. Among them, non-shaving skin preparation can be divided into three types: depilatory skin preparation, hair pushing skin preparation and detergent cleaning. Shaving skin preparation is simple and easy, but it may cause skin damage and become a base for bacterial reproduction and a source of infection.

[0003] Problems with the prior art include: 1. The shaving skin preparation method may cause skin damage, thereby increasing the risk of surgical site infection. Shaving may not only cause tiny incisions, but may also irritate or abrade the skin, providing an entry point for bacteria. 2. Traditional shaving skin preparation tools cannot adapt well to the different curvatures of the body surface, which may result in incomplete skin preparation or additional damage to the skin. 3. The traditional skin preparation process requires the use of disinfection tools, disinfectants and disinfectant carriers such as cotton wool and gauze, and the disinfectant carrier is clamped with tweezers or pliers to apply to the skin for disinfection. However, the prior art has complicated operating steps, and the shaving and disinfection steps need to be performed separately, which consumes a lot of manpower and material resources. In order to solve the above problems, the utility model proposes a medical preoperative skin preparation device for urinary diseases. Utility Model Content
