Three-dimensional printing technology revolutionizes surgery

They look like that, they look like human heart or lungs, but in fact these organs are just copies made by the company Lazarus 3D, the United States beginning with a # 39; to three-dimensional printing technology revolutionizing the field of operation.

Having located at Houston (Texas) medical center, the largest in the world, Lazarus 3D reproduces personalized copies of human and tissue organs printed in three dimensions (3D) of the study which makes tomography or MRI of the patient deadlines that are not more than 24 hours.

This method allows doctors to emulate a complex surgical operation with a precise copy of the patient's organ, and prepare before it is implemented. The company also creates generic prototypes of different parts of the body for the training of doctors. The pieces, printed in several types of silicon, imitate the mechanical features of human organs and tissue features with a high level of detail, including a tumor structure that a patient may have. "We adapt the properties of each organ to be soft, elastic or rigid, with the consistency of human tissue," said American scientist and entrepreneur Jacques Zaneveld, founder of Lazarus 3D, to Efe.
"We can have different types of materials such as liver, fat and ligament in one model, and that satisfy the same geometry that human has," he added. For Zaneveld, who has a PhD in human and molecular genetics from Baylor College of Medicine in Houston, 3D printing technology was a hobby that led to the creation of figures later sold in anime conventions and science fiction. Ultimately, he focused on his true goal, developing the technique to improve people's health. "The conventional models that were in the market were made of rigid material, so I saw the need to create soft prototypes that reconstructed human features and could be used to perfect the custom of surgery, "he said. The company aims to reduce its modeling of errors in surgeries that give the patient's life at risk. In the United States, medical errors are the third cause of death, with more than 250,000 deaths per year, according to a study published by British Medical Journal (BMJ). Zaneveld married a lot of the "lacking" lack of lacking, because "even the most specialized surgeon can make a mistake", something that solves this revolutionary technology, ; n allow "realistic exercise", with the correct materials in the right places.

"The ability to create these models for a specific patient is a new opportunity," said Larry Ciscon, president of Northworks 3D and a close colleague of the Houstonian company.

Lazarus 3D recently won a prize by NASAiTech 2018, an initiative of the Aeronautics and National Space Ministry (NASA), to find innovative ideas to solve the barriers to exploring the Moon and Mars in the future. The company has shown scientists and NASA researchers whose technique to print models of human organs in 3D can respond to technological challenges in space trips. Lazarus 3D envisages that its technology can be used in different situations in the space, such as the development of lightweight pieces to repair equipment, the creation of "artificial steel astronomers" to test the design of new space spaces or the training of medical astronauts that have to carry out operations. "There's a very good opportunity to explore the applications of our technology outside the field of medicine," said US scientist Smriti Zaneveld, research director and co-founder of L azarus 3D. As well as marketing these models with clients and hospitals in the United States, the company is distributed in Mexico, India, China and the United Kingdom, and there are & # 39; It plans to expand its market to other Latin American countries and the rest of the world. According to Daniel Olvera, a specialist in endowology and robotic surgery at the Zambrano Hellion Hospital in Monterrey (Mexico), the impression of Lazarus 3D allows to be more successful in intervention because "you can know the anatomical relatives and simulate surgery before interfering to the patient "..
