Popis: Post-surgical complications are correlated to the surgeon's technical skill level. Thus, efforts are being put in finding ways to improve the surgeon's technical skills, such as not causing unwanted damage to tissues during surgery. In this study, we aim to investigate the possibility of estimating biological tissue damage, in view of preventing unwanted damage during surgery.A series of tensile tests were performed on porcine small intestinal tissue to determine the elasticity and the tearing force. The tissue was then microscopically observed to investigate the influence of fibrous protein configuration in the tissue's mechanical properties.The results from the tensile test showed that the fracture energy had a positive and linear correlation with the elasticity to the negative 0.5th power (RWe showed that the fracture energy had a correlation with the elasticity in porcine small intestinal tissues, which was also suggested in polymer mechanics, thus being a promising avenue toward the ability to estimate the maximum applicable force onto a biological tissue without causing damage during surgery. Attention should also be pointed, however, towards investigating the extent at which polymer mechanics and biomechanics overlap.
