Effect of Manufacturing Parameters of Lightweight Hernia Mesh Material on Its Mechanical Properties

The traditional synthetic polypropylene（PP） meshes for hernia surgical repair were controversial due to increasing postoperative complications,including chronic pain,infection and shrinkage.These morbidities may be related to a mismatch of mechanical properties between abdominal wall and the meshes....

Summary:The traditional synthetic polypropylene（PP） meshes for hernia surgical repair were controversial due to increasing postoperative complications,including chronic pain,infection and shrinkage.These morbidities may be related to a mismatch of mechanical properties between abdominal wall and the meshes.The aims of this study were to design a large pore,lightweight and anisotropic hernia mesh material and explore the influence of pulling density on mechanical properties of experimental hernia mesh materials.The hernia mesh material included A,B,and C samples knitted by RS4 EL warp knitting machine with 16 E gauge.The results showed that the mechanical properties of hernia mesh materials met the requirement of anisotropy in abdominal wall tissue.With the pulling density increased,bursting strength,uniaxial tensile strength and suture pulling out force tended to increase,while tearing force was no significant difference.Sample C showed superior physical and mechanical properties.
