It’s vital that surgeons, whether operating on humans or animals, are familiar with how body tissue feels and reacts before conducting their inaugural operation. However, until recently, many veterinarian students were practicing basic surgical and suturing procedures on carpet pads and pig’s feet before moving on to their first “live” patient. But an invention by Colorado State University (CSU) veterinarians has provided students with a substrate that is infinitely closer to the real thing by developing artificial body parts that closely resemble real skin, muscles and vessels – they can even bleed! Of course the real benefit is that no animals (or humans) are hurt in the procedures.
