| Popis: | A selection of hernia meshes is a compromise between their biocompatibility and mechanical performance. A critical evaluation of prosthetic materials was presented, comparing the elasticity and level of orthotropy of three different brands of hernia meshes and abdominal fascia.Uniaxial tensile and relaxation tests were performed with human abdominal fascia and hernia meshes. The experiments were performed with velocity of elongation for tensile tests—0.13 mm/s and for relaxation experiments—1.26 mm/s. The investigation of elastic properties included 96 specimens from umbilical and transversalis fascia taken from 16 donors, as well as 30 mesh samples. Relaxation experiments were performed with 17 samples of fascia umbilicalis and other 30 mesh samples. The samples were cut in two orthogonal directions.The values of elastic modulus E for the investigated hernia meshes were calculated and compared with the elastic modulus of abdominal fascia. The elastic module in longitudinal direction of the invest... |
