    SYNTHETIC SURGICAL MESH
    Field of the Invention
    The present invention relates to a surgical mesh intended to be implanted in living bodies, in particular for the repair of hernia defects of the abdominal wall, more specifically of the anterior abdominal wall, of a patient, made by synthetic filaments woven from a biologically material. compatible
    Background of the invention
    Various devices of the stated type are already known, intended to correct or correct the emergence or emergence of a certain tissue outside the cavity in which it should normally be housed, retaining said fabric or device with said fabric in the corresponding cavity, being one of the most common cases of an abdominal hernia. For this, there are already several documents that reveal a mesh or network for the cases cited.
    Indeed, document US 2009/0326565 is known which deals with a lightweight surgical mesh based on a two-comb warp fabric with a quadrangular pattern that defines a mesh described as isotropic, which has two axes perpendicular to each other, and of two other axes perpendicular to each other, but rotated between 302 and 602 with respect to the first pair of axes. In the same document it is specified that the warp threads run along said axes, and that they are arranged in parallel and regularly spaced.
    Another document, US 5559273 discloses a hexagonal surgical mesh fabric, and describes that the fabric is a double-sided machine-made warp fabric with polypropylene monofilament threads.
    On the other hand, document US 2008/0147198, similar to the previous one, explains a prosthetic replacement fabric, based on an orthogonal surgical mesh of uniform pattern and tissue system based on having two interwoven warp directions, determining a plurality of polygonal openings formed with several filaments on which a pair of filaments that delimit sub-openings have been extended.
    and US2012 / 0304702, for its part, discusses a method for the manufacture of a knitted surgical mesh, describing the tissue system obtainable in a straight knitting machine.
    The invention proposes a new architecture for the manufacture of a surgical mesh specially designed for the correction of abdominal wall hernias with biomechanical characteristics different from those disclosed in the previous documents. Brief Description of the Invention
    Thus, unlike the aforementioned background, based on meshes with parallel filaments in two or more axes, and having an asymmetric physical behavior, the present invention provides a surgical mesh that presents a concentric construction of symmetrical behavior, which favors a distribution of homogeneous stresses on the periphery of the mesh, which is one of the weak points of the state of the art meshes and where recurrences occur. Said symmetrical behavior is especially indicated for the biomechanical peculiarities of the abdominal wall.
    In fact, the invention proposes a synthetic, implantable surgical mesh for the repair of hernia defects of the abdominal wall, more specifically of the anterior abdominal wall, of a patient made by means of woven filaments of a biologically compatible material in which:
    • The aforementioned filaments that are made of a biocompatible, non-absorbable polymeric material are woven forming a crochet fabric that is crochet technique, with a structure comprising a central core for holding the body of the mesh and a plurality of concentric rings that start of said core, around it, delimiting concentric circular crown openings; Y
    • the different rings are connected to each other by means of radial connecting filaments, spaced apart, which extend over each of the annular openings, providing together a symmetrical structure.
    This mesh geometry of the invention provides the aforementioned symmetrical behavior, regular throughout its length, with a consequent distribution of homogeneous stresses throughout the periphery of the mesh itself.
    In one embodiment, said biocompatible, non-absorbable polymeric filaments are combined with filaments of resorbable polymeric material, known per se, preferably of the polyglycolic type.
    Other features of the invention will appear in the following description of an exemplary embodiment given by way of illustration and not limitation.
    Brief description of the drawings
    In order to facilitate the understanding of this description, a sheet of drawings is attached in which:
    Figure 1 illustrates a plan view, in which the aforementioned example of the surgical mesh is outlined.
    and figure 2 corresponds to an enlarged detail of the central area of the previous figure 1.
    Detailed description of the invention
    Thus, as illustrated in said figures, a circular contour mesh 2 formed by a knitted fabric consisting of filaments of a biologically compatible material, in particular of a biocompatible, non-absorbable polymeric material that has been selected from the group of polyolefins, can be seen. and is preferably polypropylene.
    The mentioned mesh 2 has a central support or support core that in this example is annular although it could have other structures depending on the methodology of obtaining, from which a series of concentric rings 4 move away from each other, the said ring being distinguished central or inner core 4c and an outer ring 4e.
    Said concentric rings 4, 4c, 4e woven as a crochet fabric define openings 6 as a circular crown concentric with each other.
    The said concentric rings 4, 4c, 4e are joined together by radial filaments 8 generally distributed generally, giving the assembly a symmetrical structure and providing a series of openings or pores of the mesh.
    Each of said rings 4c, 4, 4e integrates an annular core on which one or more windings of the radial connecting filaments extend. Likewise, said radial filaments generally comprise two or more stretches of filament interwoven to the adjacent rings.
    It should be noted that, initially, such circular crowns are equidistant from each other, that is, they are separated from each other with equal distances "d", although they could also have different distances from each other, giving rise to circular openings 6 of different width.
    Also, it should be mentioned that both the inner ring or core structure 4c of the mesh 2 and the outer ring 4e thereof are thicker than the remaining rings 4 in order to ensure adequate resistance to the structure.
    Optionally there will be radial lines of two filaments 8p closer to each other than the 5 adjacent filaments 8, and said radial lines of filaments 8p will be arranged according to different angularities equal to OR.
    As indicated and according to the present exemplary embodiment, said filaments 8, 8p as well as rings 4, 4c, 4e are constituted in a biocompatible, non-absorbable polymeric material selected from the group of polyolefins and which is
    10 preferably polypropylene.
    According to said embodiment, it is provided that said biocompatible, non-absorbable polymer material is combined with filaments of resorbable polymer material especially indicated for surgical applications, selected from among the aliphatic polyesters and preferably of polyglycolic type.
    15 Depending on the type of hernia or the characteristics of the patient to be treated, it has been foreseen that the mesh can have a variable pore size and for that purpose in its construction the different rings can be equidistant or not and the network of radial filaments also It may be equidistant or not and may have a certain distribution of the inter-filament distances preset according to the requirements of the hernia to be repaired.
    A person skilled in the art could introduce changes and modifications in the described embodiment, without departing from the scope of the invention, as defined in the appended claims.
