It is inevitable that traumatic injuries are sustained in daily life, and it is inevitable that stitches will be required. In order to reduce the production of suture scars, more and more people will choose the ultra-decrease tension fine suture, today introduces the difference between these two types of suture. First, the definition of 1, general surgical suture Surgical suture is more focused on the recovery of function, is the most basic type of operation in surgery. According to different parts, the anastomosis will be slightly different. For example, in vascular surgery, a special vascular suture is needed to anastomose the broken end or end side of the blood vessel, and a continuous suture is generally used for large blood vessels. There is also reconstruction after resection of gastrointestinal surgery, which may require instruments, such as gastrointestinal anastomosis, linear cutting anastomosis, through the instruments can make the suture become more simple and efficient. Ultra-decreasing fine suture Ultra-decreasing fine suture is more focused on the appearance of the recovery, is more and more plastic surgery using the suture. Ultra-decreasing fine suture is to make a distant anchor point in the dermis and then use suture to make a deep suture, which is very careful about the site and level of the needle, the line of the thread in the tissues, the site and level of the needle, the tightness of the thread and the distance between the stitches and the margins. After suturing the surface of the skin will be easy to lean together, and in the body of the epidermis so that he protrudes part of the bulge with the extension of time, the bulge slowly flatten, but the wound will not be widened. This clearly shows that the ultra-decreasing fine suture focuses on minimizing the skin tension in the affected area and restoring the appearance. Second, the suture line 1, general surgical suture using 5-0 suture, the diameter is 0.1mm, 6-0 suture diameter is 0.07mm, 7-0 suture diameter is 0.05mm 2, ultra-decrease tension fine suture, decrease tension fine suture is generally used in the subcutaneous tissue layer with 5-0 # absorptive thread, the skin layer with 6-0 # or 7-0 # non-invasive suture, yellow hair is generally 0.06-0.09mm, plastic and cosmetic surgery is generally 0.06-0.09mm, plastic and cosmetic surgery is generally 0.06-0.09mm. -0.09mm, plastic and cosmetic bone surgery suture is actually thinner than hair. Third, the effect of suture 1, general surgical suture is often used in a one-time direct suture, because not to do the decompression treatment, the wound healing may be due to tension factors leading to leave earthworm-shaped or centipede-shaped scars, affecting aesthetics or leading to limb function limitations. 2, ultra-decrease fine suture generally use layered suture, greatly reducing the skin tension, the wound surface is elevated after suture, so that there will be no gap between the trauma, can effectively reduce the incision skin tension, to ensure that the skin around the scar blood flow, to improve the success rate of incision healing, so that the degree of incision scar hyperplasia to a lower level, so that the postoperative incision is “flat as the first time! The postoperative incision will be “as flat as the first time”.
