Around the naked eye they look like a heart or lung of a human being, but in reality these organs are precise replicas made by the company Lazarus 3D, an American startup with its technology three-dimensional printing revolutionizes the field of surgery.
Located in the medical center of Houston (Texas), the world's largest, Lazarus 3D reproduces personalized copies of human organs and tissues printed in three dimensions (3D) from a study that makes a tomography or MRI patient deadlines that sometimes do not exceed 24 hours.
This method allows physicians to simulate a complex surgical operation with an exact copy of the patient's body, and prepare yourself before you operate it.
The company also creates generic prototypes of various parts of the body for the training of resident doctors.
Parts, printed in different types silicone, imitate the mechanical properties of human organs and tissue characteristics with a high level of detail, including the structure of the tumor the patient may have.
"Adjust the properties of each organ as soft, elastic or rigid, with the consistency of human tissue"comments the American scientist and businessman Efe Jackues Zaneveld, founder of Lazarus 3D.
"In one model, we can have different types of materials such as the liver, fat and ligament, and they are in line with the same geometry that a person has," he added.
For Zaneveld, a PhD in human and molecular genetics Bailor College of Medicine from Houston, 3D printing technology was a hobby that led him to create figures that he later sold in the conventions of Anime and Science Fiction.
In the end, he focused on his true goal, the development of a technique to improve human health.
"Conventional models that were on the market were made of solid material, so I saw the need to create soft prototypes that have repeated human characteristics and could be used to perfect the practice of the operation," he said.
The company seeks to reduce its error models in operations that endanger the life of the patient. In the United States, medical errors are the third cause of death, with more than 250,000 registered deaths per year, according to a study published by the magazine British Medical Journal (BMJ).
Zaneveld attaches a great deal of guilt to the lack of "adequate preparation" because "even the most modern surgeon can make a mistake," something that solves this revolutionary technology, which allows "real practice" with precise materials at exact points.
"The ability to create these models for a particular patient is a new opportunity," says Larry Ciscon, president of Northvorks 3D and a close associate of Houston.
Lazarus 3D recently received an award from NASAiTech 2018, the initiative of the National Administration for Aeronautics and Space (OUR), find innovative ideas that address obstacles to future research for the Moon and Mars.
The company has shown NASA scientists and researchers that its technique for printing models of human organs in 3D can provide solutions to technological challenges in space missions.
Lazarus 3D predicts that its technology can be used in various scenarios in the universe, such as the production of pieces of light for repair equipment, the creation of a "artificial astronaut" to test the design of new space suits or to train medical astronauts. They have to carry out operations.
"This is a good opportunity to explore the application of our technology beyond the medical field," said American scientist Smriti Zaneveld, director of research and co-founder of Lazarus 3D.
In addition to marketing these models with clients and hospitals in the United States, the company distributes them Mexico, India, China and the United Kingdom, and they intend to expand their market to other Latin American countries and the rest of the world.
According to Daniel Olvera, an urologist specializing in endourology and robotic surgery in Hospital Zambrano Hellion in Monterrey (Mexico), the impression of Lazarus 3D allows you to be more successful in the intervention because "you can know anatomical relationships and simulate the operation before you intervenes the patient."
