| Popis: | Skin Stapler is an alternative instrument, which makes surgy easily and quickly and owns fine-looking effect without scars after the wound healed, to traditional surgical suture for the wound skin sewing. Magnesium recently is considered to develop medical implants because of its beneficial biocompatibility and bioabsorability. Due its less mechanical strength than traditional 316L stainless steel used in common staple, this paper try to optimize the structure of pure magnesium skin staple by FEM models and simulation as so to assure its biomechanical safty. Using ADINA software, two staples with different pre-bended shoulders and the traditional staple without shoulder are modeling to analyze its stress and plastical strain during structural deformation under load. The results, not only of pure magnesium models but also of 316L stainless steel models, showed that the shoulders optimization on staple structure has important role in its mechanical performance. The research increases the possibility of bioabsorable magnesium material application on medical skin staple. |
