Abstract
Description
Background Art
[0002] Hypertrophic scars are a type of skin lesion formed by excessive proliferation and repair of new connective tissue after damage or lesions to the dermis or deep tissues. Hypertrophic scars protrude from the skin surface, with irregular shapes, uneven heights, flushing and congestion, and a tough texture. Their appearance is not good, which may affect their image, and they often cause burning and itching, causing a lot of inconvenience and pain to patients. In addition, this type of scar hyperplasia lasts for a long time, sometimes for many years, so the treatment of hypertrophic scars is a routine clinical item. At present, the simplest and most effective treatment for scar hyperplasia is scar needle injection, which is to directly inject the drug injection into the scar for treatment. The main component of this drug is steroids, and its main function is to inhibit scar growth and accelerate the degeneration of hypertrophic scars to achieve a reduction in the height of the protrusion, darkening of the color, subsidence of congestion, softening, and disappearance of discomfort. However, the main problem with scar needle injection is injection pain. Due to the excessive growth of fibrous tissue in hypertrophic scars, the scar tissue structure is dense and hard, which leads to high tension and strong pain when injecting drugs into the scar, which greatly affects the acceptance of the treatment operation, especially for patients with low pain threshold and children with poor self-control. It is difficult to implement, and general anesthesia may be required when necessary, which brings many inconveniences to the injection treatment of hypertrophic scars. Therefore, it is urgent to invent a painless scar injection treatment microneedle patch to solve the above problems. Summary of the invention
