Three-dimensional printing technology revolutionizes the operation


HOUSTON.- At first glance they look like a heart or lung of a human being, but in reality these bodies represent the exact replica of Lazarus 3D, an American startup that revolutionizes the field of surgery with its three-dimensional printing technology.

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 procedure with an exact copy of the patient's organs and prepare before surgery.

The company also creates generic prototypes of various parts of the body for the training of resident doctors.

Parts printed on different types of 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.

"We adapt the properties of each organ to soft, elastic or rigid, with the consistency of human tissue," said American scientist and entrepreneur Jackues Zaneveld, founder of Lazarus 3D, in Efe.

"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, who holds a Doctorate in Humanities and Molecular Genetics at Bailor Medical School in Houston, 3D printing technology was a hobby that led him to create figures that he later sold to 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 leading cause of death, with more than 250,000 deaths per year, according to a study published in the 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's company.

Lazarus 3D recently won the NASAiTech 2018 Prize, an initiative of the National Aeronautics and Space Administration (NASA), to find innovative ideas for solving obstacles to future exploration of 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 in Mexico, India, China and the UK, and they intend to expand their market to other Latin American countries and the rest of the world.

According to Daniel Olveri, an urologist specializing in endourology and robotic surgery at the Zambrano Hellion Hospital in Monterrey, Mexico, the impression of Lazarus 3D makes it more successful in intervention because "you can know anatomical relationships and simulate surgery before intervening with the patient."
