Určení mechanických vlastností chirurgických řezů spojených šitím a kolagenními lepidly na kůži

Abstract

The aim of this work is to compare mechanical properties of sutures and tissue adhesives used for wound closing. In the first part there is a description of available commercial methods for wound closing. The next part is experimental. It contains results of tested pork skin samples which went through a tensile test. Samples were divided into two groups. The first group contained samples with wound on the skin surface and the second one contained samples with wound going through the thickness. Considering the strength of the connection, in this case sutures are much better than tissue adhesive. The last part was focused on FEM analysis and figuring out the value of Young’s modulus for tested pork skin sample. According to simulations done the value of Young’s modulus was approximately 790 kPa.
