Multifunctional hernia patch

Abstract

This invention is associated with surgical implants with anti-adhesive, antibacterial and hemostatic properties to use in hernia repair. These implants comprise: a) Bilayer intraperitoneal mesh, whichhas certain thickness and porosity was prepared with combination of PP Mesh and blend system of biodegradable polyester-based polymers and polysaccharides coated on PP layer as nanofibers via electrospun technique, and, b) Double and / or triple-layer extraperitonal composite mesh, was prepared with blend systems of biodegradable polyester-based polymers and / or polysaccharides formed on PP / polyester woven material via different coating methods.

Description

technical field [0001] The present invention discloses a composite mesh with anti-adhesion, antibacterial and hemostatic properties, which is used after intraperitoneal and extraperitoneal hernia surgery to accelerate tissue regeneration and avoid postoperative complications. Design of mesh composites using electrospinning and weaving methods. Background technique [0002] Membranes that act as a physical barrier and prevent tissue adhesions are known as "anti-adhesion membranes." Tissue adhesions are frequently observed after intraperitoneal and pelvic surgery. Trauma, infection, pain, and dysfunction are other major concerns for patients during the healing process after such surgery [Linsky et al., 1991, Matsuzaki et al., 2014]. Especially after hernia surgery, many of these complications are common and require additional medical treatment or even a second surgery to remove the mesh implant [Lim et al., 2008, Collage et al., 2010]. Therefore, anti-adhesion films are use...
