PROSTHESIS AND ITS PRODUCTION METHOD Russian patent published in 2017 - IPC A61F2/00 D04B1/08 D04B21/12 

FIELD: medicine.

SUBSTANCE: group of inventions relates to prosthesis for tissue recovery and namely to surgical silk mesh device, used for stable sutured structure. Implanted surgical mesh includes fabric consisting of, at least, two threads of yarn, differentially engaged with each other in certain pattern to form multiple connections. In each of multiple connections threads are fixed in such order, that, in fact, disengagement of threads of yarn from each other is retained, when applying tension to tissue in fabric mesh cutting, in which mesh has circuit of pattern, which defines area of separation between separate meshes to provide control both for correction of length of separate mesh and control of tool for separation of separate surgical meshes. In compliance with second version, implanted surgical mesh comprises fabric, in which certain pattern of threads generates multiple holes, promoting tissue growth, and where yarn threads are woven yarn threads made of silk fibre, woven together to form strands and further combination of three obtained strands. Method for production of connected mesh for prosthesis includes four movement of sutured product: two displacement in direction of the hilum and two displacement in direction of row. Two displacement in direction of hilum include application of the first set and the second set of threads in the direction of hilum. First set of yarn threads and second set of threads yarn in turn is applied to form loops in staggered order, and first set of threads are woven with second set of yarn threads, thus making nodes for associated mesh. Alternating application of first set of yarn threads and second set of threads yarn causes the fact, that first set of threads has different tension relative to second set of yarn threads in nodes. Difference in tension, in fact, prevents untangling of associated meshes, while cutting, wherein yarn threads are made of silk, depleted of sericin, and in which method generates pores in mesh.

EFFECT: group of inventions provides biocompatible surgical silk mesh device for use in soft and hard tissue recovery.
