In everyday life, bumps and bruises are inevitable. Small wounds are usually fine with a Band-Aid or a reduction sticker. If it is serious, you need to go to the hospital for stitching. The stitches are painful and painful. When the stitches are removed, it is inevitable that you will experience some discomfort again. As medical standards continue to improve, medical companies have invented painless suture patches, which are ideal for daily treatment of small wounds that require stitches before, when using just a light paste to the wound, gently pulled tight, without the need for wound closure. This suture patch is more conducive to wound healing than a Band-Aid that is sealed and impermeable. There are four zipper-like strings on the top of the suture. As there are tiny cogs on the threads, they are like a zipper, and when pulled tight, the wound that was originally expanding outward will fit tightly together without the need for stitches. The tension provided by the zipper is enough for the wound to heal. After the wound has healed, the sutures can be torn off directly. In addition to not having to endure the pain of stitches, the biggest advantage of the suture patch is that it leaves almost no centipede scars. So far, the clinical use of this painless suture patch has become more and more widespread, which not only reduces the patient’s pain, but also prevents scarring.
