NTU’s Likelike 3D Printed Hearts Transform Surgeon Training

3D printing has made a remarkable impact in the medical field. From the training of future doctors to new and improved medical techniques, this technology has proved to be an increasingly valuable tool. Recently, a team of researchers at Nottingham Trent University (NTU) in the UK designed an artificial heart to train doctors in transplant surgery. This 3D printed model, crafted from materials like silicone and tissue, faithfully replicates the behavior of a natural human heart, mimicking its pulsation and blood flow. The aim of this research is to enable surgeons to familiarize themselves directly with the technical aspects of this type of surgery, in order to improve transplant results.

In general, surgeons typically train using cadavers or animal specimens, but these options have limitations in providing realistic training scenarios. Recognizing this challenge, researchers at Nottingham Trent University turned to 3D printing as a solution for creating lifelike surgical training models. Spearheaded by Richard Arm, a former film visual effects artist, the project focuses on developing 3D organ models that accurately replicate the behavior of real organs. Arm’s latest creation, a heart model, stands out as the closest match to the intricate characteristics of the human heart yet achieved.

How Are 3D Printed Hearts Made?

The heart models are specially designed to take account of patients’ specific conditions. In other words, these artificial organs reproduce patients’ pathological conditions to help doctors in their treatment. By simulating bleeding during incisions, these models recreate real-world scenarios, allowing practitioners to refine their skills and practice techniques for controlling bleeding effectively. Moreover, these models feature realistic tactile characteristics thanks to texture variations that reflect the diversity of heart tissue.
