Negative-pressure wound treatment method used for prevention and treatment of scarring hyperplasia at surgical suture

Abstract

The invention provides a technical method of negative-pressure wound treatment method used for prevention and treatment of scarring hyperplasia at the surgical suture. Implicit factors of scar hyperplasia are mechanical stress, infection, inflammatory reaction and foreign body reaction of wounds. Among the implicit factors, wound tension plays a key function in the scar formation. Frequently-used scar prevention and treatment methods such as Silicone gel, pressure therapy, hormone injections and the like are poor in curative effect or has side effects. The negative-pressure wound treatment method is a novel prevention and treatment for wounds and scars at the surgical suture. Based on the structure and working principle of the negative-pressure wound treatment, the scarring hyperplasia can be effectively inhibited through closing, fixing and pressing the sutured wounds and playing continuous negative-pressure action on the wounds; at the same time, the main factors leading to the scar formation are intervened. The intervention process comprises the following steps: the tension of the wound tissue is remarkably alleviated; the wounds are closed; the wound healing is accelerated and the tissue inflammation is reduced, so that the scarring hyperplasia is effectively restrained. The negative-pressure wound treatment method is used for scar prevention and treatment of various surgical operation suture wounds, such as plastic surgery, beauty surgery, burn surgery, cardiothoracic surgery, head and neck surgery, maternity surgery and the like.

Description

technical field [0001] The invention relates to a technical method for preventing and treating scar hyperplasia in surgical suturing wounds in the field of surgery, including the prevention and treatment of scars in various surgical suture wounds such as plastic surgery, cosmetic surgery, burn surgery, cardiothoracic surgery, head and neck surgery, and obstetrics and gynecology. Background technique [0002] Scar is an inevitable product after skin injury repair, and the healing of human skin injury will be accompanied by different degrees of scar formation. The pathology of scar hyperplasia is characterized by a unique tissue structure: hypervascularization, inflammatory cell infiltration, fibroblast proliferation, and a large amount of disordered extracellular matrix produced by fibroblasts. Clinically, scars are characterized by color changes, protruding skin or depressions, pain, itching, hardness and contraction, causing physical discomfort, appearance damage and psycho...

Problems solved by technology

Although silicone gel, pressure therapy, hormone injection, laser and radiation therapy are widely used in the prevention and treatment of scars, the mechanism of action of these therapies is not clear, the curative effect is inaccurate, or there are serious side effects[1,2], making surgical resection still an option. The common method of scar clinical treatment, surgical treatment includes scar excision and reconstruction, skin grafting, tissue expansion and flap transplantation, and even try comprehensive transplantation to treat severe facial scar hyperplasia deformity, but surgical treatment faces pain, anesthesia accident, high cost and surgical post-recurrence issues
