Abstract:
Surgical mesh is a medical device that is used to provide additional support to weakened or damaged tissue. The majority of surgical mesh devices currently available for use are constructed from synthetic materials or animal tissue, surgical mesh made of synthetic materials can be found in knitted mesh or non-knitted sheet forms. The synthetic materials used can be absorbable, non-absorbable or a combination of absorbable and non-absorbable material Permanent meshes remains in the body, whereas temporary ones dissolve over time. Surgical Mesh provides medical textiles for the manufacture of hernia mesh. polypropylene monofilament mesh were chose to repair hernia both for, physical performance, biological inactivity and compatibility, open knit construction allows in-growth of host tissues and encourages natural repair, Unique knitting mesh design, Flexible, strong, elastic transparent & mesh, non-absorbsorbable, inert and porous no shrinkage provides long term material stability important to counter muscular contraction and Excellent multi-directional mechanical properties and exceptional resistance to tearing. Generally, PP weft knitted mesh fabrics (50 courses per centimeter) were fabricated using (PASSAP DEUMATIC 80) weft knitting machine. The heat treatment conditions are confirmed on the basis of trials. It can be concluded that the heat treatment low temperature between and the time 5 minutes Second one uses the method fabric mesh passing from ASTRON machine fussing time = 20min ,tempure = 190 c° Speed = 5m/min,time = 10 sec, benefit the mechanical properties of the mesh. The prototype PP mesh were characterized the Geometrical characteristics,
