DOUBLE LAYER ANATOMIC SURGICAL MESH

摘要

A mesh (1) made of monofilament polypropylene (PPL) is disclosed, with surgical quality (CQ) and controlled flat memory (CM), comprising an upper (1') and lower (1") layer joined by welding along almost the entire length of their edges (p) resulting smooth, polished and without ravel; said layers comprise equal coaxial holes (2', 2") for passage of the spermatic cord, two radial slits (3', 3") departing from said holes and forming an angle ( OMEGA ) between 90 DEG and 120 DEG , the zone (q) of the edges between said slits being not joined and free so as to create an upper (5') and a lower (5") fins that can be easily bent. By folding said fins, lowering the upper fin (5') and raising the lower fin (5") respectively, they are firstly opened so as to make easier the subsequent folding and closure by overlapping tucking of the lower fin (5") above the upper fin (5') so as to self block the mesh. Said mesh does not require the suture of the fin openings that in the prior art meshes when not effected causes deformation and misplacement by spreading apart said fins, while when effected causes lack of capability of the mesh to stay flat by bending along the slit, with formation of dead space and serum accumulation, all being primary reasons of relapsing phenomena. The double layer confers ideal stiffness to the mesh however without inpairing the need of accelerated fibroplastic infiltration by the presence of through holes (4', 4"). The mesh finds a particular application in surgical hernia operations, more particularly in hernioplasty with properitoneal (rear) approach with mesh implant.
