Definitions
- the invention relates to a three-dimensional and openwork knitted wall reinforcement which is useful, for example in parietal and / or visceral surgery, but which can be applied to other fields of surgery.
- FR-A- French patent application
- an openwork knitted fabric formed by monofilaments of a biocompatible polymer material, such as polyester, polyamide or polypropylene, worked in an open mesh weave which is not blocked forming, in the plies constituting the walls, respectively front and rear of the knitted fabric, a multitude of cells of substantially polygonal shape. These cells give the knit a balanced dynamometric behavior, that is to say offering substantially the same resistance to elongation and the same possibilities of elastic return at least in the two main directions, namely lengthwise and crosswise.
- a biocompatible polymer material such as polyester, polyamide or polypropylene
- the ply (s) constituting the front wall of the knitted fabric is linked to the ply (s) constituting the rear wall by a bracing made up of one or more plies of which the stitches taken with the stitches of the front and rear walls are connected by long floats.
- this or these connecting plies increases the surface mass of the knitted fabric and tends, if they are produced by monofilaments, to decrease the conformability and the flexibility of the knitted fabric, even though parietal repair surgery wishes, on the contrary, flexible, porous knitwear with a low surface mass.
- the object of the present invention is to provide a wall reinforcement which overcomes these drawbacks and the knitting of which has, lengthwise and crosswise, the same characteristics of resistance and elasticity, while improving its flexibility and conformability, without affecting its low density and high porosity.
- the bracing of the plies forming, respectively the front wall and the rear wall of the knitted fabric is provided by the monofilaments of one of the plies making up one of the walls of the reinforcement, each of these monofilaments forming, after a constant number of rows of stitches in the ply, one stitch with one of the stitches in one of the plies on the other side of the knitted fabric.
- the front wall which comprises, at regular intervals, meshes intertwined with the meshes of one of the plies of the rear wall, to ensure the connection and the maintenance of the two walls.
- each section of monofilament which extends between the mesh formed in the front wall and the mesh formed in the rear wall ensures excellent resistance of these two walls due to its nervousness or rigidity and thus makes it possible to limit the number of mesh forming a spacer, avoiding influencing the dynamic characteristics of the reinforcement obtained.
- FIG. 1 is a partial side view in cross section representing a knitted fabric braced by an intermediate ply
- FIG. 2 is a side view in cross section of the fabric according to the invention.
- Figures 3a and 3b show, for an embodiment of knitting according to the invention, the binding graph of the two plies constituting, respectively, the rear wall and the front wall
- FIG. 4 is a front image of a knitted fabric according to the invention, taken by scanning electron microscopy with an enlargement of 20.
- the columns of meshes AV and AR each schematize the two layers of meshes formed, on a Rachel loom with double needle bed, by monofilaments of a bio-compatible material and, for example, polypropylene monofilaments.
- connection between the front and rear walls is ensured by an intermediate ply N, alternately forming, every six rows, a stitch m1 on one of the plies of the rear wall of the knitted fabric, then a stitch m2 on one of the plies of the front wall, before forming a float F on the next six meshes until the achievement of the next mesh m1.
- this connection is made in different knitting columns and, for example, every two columns, with an offset of the rows in which the loops m1, m2 are formed.
- FIG. 1 represents the current structure of the knitted reinforcements and highlights that, when the plies are extended, the long floats F have little possibility of following the elongation movement, and in any case less than a stitch whose the loop can be closed to make thread, and therefore help to modify the dynamometric characteristics of the reinforcement.
- FIG. 2 which corresponds to knitting according to the invention, shows that the connection of the front walls AV and rear AR is ensured, for example every two columns and every six rows, by one of the monofilaments 2 constituting one of the two plies of one of the walls and, for example, of the front wall AV, this monofilament forming a mesh M on a mesh of one of the two plies making up the rear wall AR. Thanks to this, and except for the sections 2a of monofilament 2 extending between the two walls of the knitted fabric, there is no other element, such as float, between these two walls.
- Figures 3a and 3b show the bonding grids of the two plies constituting, respectively, the rear wall and the front wall of a knitted fabric according to the invention produced according to the scale below.
- front wall tablecloth a) 0.1.1.1/1.2.2.2/3.4.4.4/5.4.4.4/4.3.3.3/2.1.1.1/7 tablecloth b) 5.4.4.4/4.3.3.3/2.1.1.1/0.1.2.1/ 1.2.2.2/3.4.4.4/// rear wall: coated e) 4.4.5.4/4.4.4.3/3.3.2.1/1.1.0.1/1.1.1.2/2.2.3.4// tablecloth d) 1.1.0.1/1.1.1.2 /2.2.3.4/4.4.5.4/4.4.4.3/3.3.2.1/////
- This knitting is made with polypropylene monofilaments having a size between 0.07 and 0.14 millimeter and, preferably,
- the filaments are worked in an Atlas type weave locally forming a mesh M on certain needles of the rear structure, simultaneously with the formation on these needles of stitches m3 constituting one of the two plies of the rear wall.
- This weave makes it possible to produce the knitting appearing on the enlargement of FIG. 4 where M represents the mesh coming from a front ply AV and forming a double mesh with a mesh m3 of one of the plies of the rear wall AR, arranged in foreground.
- the knitted fabric has an openwork structure having a high porosity with a low density. It also shows that, thanks to their distribution on the sides of the polygons, the open unblocked meshes give the knitted fabric substantially the same possibilities of deformation in longitudinal and transverse, corresponding in FIG. 4 to the directions, respectively, vertical and transverse.
