Description

Technical Field

[0001] The utility model relates to the field of skin preparation knives, in particular to a special skin preparation knife for anus. Background Art

[0002] The function of the skin preparation knife is to remove the hair at the operation site, so as to achieve the effect of cleaning the skin and reduce the number of bacteria on the skin surface to prevent the hair and bacteria from remaining and contaminating the wound, thereby causing infection. Its structure usually includes a bottom plate, comb teeth are arranged on both sides of the bottom plate, a handle is fixedly connected to the bottom of the bottom plate, a blade is arranged on the upper side of the bottom plate, and a top plate is arranged on the upper side of the blade. The blade, top plate and left and right sides of the bottom plate are all straight structures. When operating at the anus, due to the special shape of the anus, the blade has a straight blade, which is easy to scratch the skin when used to scrape the anus. The Chinese utility model patent with application number 202120509714.0 discloses an anal skin preparation device for clinical anorectal surgery. By replacing the traditional flat razor with a conical skin preparation blade head, it is convenient for the blade head to remove the hair on the inner side of the anus. At the same time, the high degree of fit between the blade head and the shape of the anus can also avoid the problem that the blade head may cause damage to the skin near the anus. A hair removal device is added, and a small vacuum device is externally connected to the upper opening of the pores of the hair removal device. The removed hair is absorbed into the pores through the protective net of the conical protective shell to prevent the removed hair from scattering near the anus or staying inside the conical skin preparation blade head and cannot be removed in time, causing skin infection near the anus.

[0003] The anal skin preparation device for anorectal clinical surgery uses a principle similar to that of a razor to shave the hair outside the anus. However, during use, it was found that it had defects: 1. The hair at the anus is long, unlike the short and straight beard, and it is not easy to insert into the razor hole, so shaving is not as convenient as scraping; 2. The blade head is not a structure that matches the convex arc of the anus, and it is still not easy to fit the anal skin during use, which is not conducive to shaving hair; 3. The hair removal device requires a dust suction device, which is more complicated in structure and not conducive to reducing costs. Utility Model Content
