Surgical Training Model having Temperature Indicating Function

Abstract

This paper reports the stereoscopic model of three-dimensional blood vessel having a temperature Indicator for measurement of temperature variation during surgical training. This model consists of two hydrogel materials to mimic Young's modulus of human artery and rapid fabrication of the model using photo-polymerization. Polyethylene glycol diacrylate (PEGDA) is used for photo-crosslinkable resin and polyvinyl alcohol (PVA) is used to mimic surface properties of the blood vessel. Reversible temperature indicator is impregnated into the blood vessel model to visualize the temperature change of the model. The vessel model is fabricated by dip coating on the wax model, photo-polymerization, and lost wax method. We demonstrate color change of the fabricated vessel model by heating of the model.
