3D printing opens a new chapter in medical science 3D printing big inventory

In recent years, the development of 3D printing technology is very rapid. Even the industry once thought that 3D printing will lead the third industrial revolution. Compared with traditional manufacturing, 3D printing has a breakthrough in traditional design space, personalization, small batch and high precision. Advantage. In addition, because the medical industry rarely has standard quantitative production and avoids the disadvantages of 3D printing, 3D printing has taken the lead in obtaining breakthroughs in the medical field. Today, Xiaobian has taken a look at the application of 3D printing in medical applications.

Prosthetic aspect

The human body is very complicated, and each person's body has different nuances. Therefore, the traditional prosthesis is difficult to tailor for each patient, and the appearance of 3D printing just solves this problem.

Two-year-old Emma Lavelle suffers from congenital multiple articular contracture (AMC), which prevents her muscles and joints from growing and stiffens muscles and joints. Therefore, Emma's athletic ability is severely limited. She has undergone multiple surgeries and corrections. One of the most promising treatments in the AMC approach is the WREX device, a body cast with elastic bandages and prosthetic joints that help AMC patients lift their limbs.

The problem is that Emma is too young to fit in this typical WREX device. So two researchers, Dr. Tariq Rahman, and designer Whitney Samper have developed a smaller version of the WREX device for the Emma.

With a smaller 3D print, two researchers were able to print small parts of the reduced version of the WREX design. This 3D printer does not use metal, but uses ABS plastic to make new parts. Experiments prove that these materials are very strong enough to support Emma's daily use. Now Emma is now free to move her arms, play toys like normal children, eat for herself, and even embrace parents without the help of parents. 3D printing technology has changed the life of Emma.

3D printing organ

In January of this year, at the Children's Hospital of Miami, a 4-year-old girl, Adanelie Gonzalez, who had "complete pulmonary venous malformation (TAPVC)", had a weak immune system due to her breathing difficulties. She could only survive for weeks without corrective surgery. Even a few days.

With the help of a 3D heart model, cardiovascular surgeons have successfully developed a complex corrective surgical plan by completely replicating the 3D model of the little girl's heart. In the end, according to the plan, a permanent operation was successfully carried out for the little girl. Now the blood of the little girl resumes normal flow and the body gradually returns to normal during treatment.

3D printing pharmaceutical

In August of this year, SPRITAM (levetiracetam) instant tablets prepared by Aprecia Pharmaceuticals using 3D printing technology were approved by the US Food and Drug Administration (FDA) and will be officially sold in 2016. This means that 3D printing technology will further move into the pharmaceutical field after printing human organs, which is of great significance for the realization of precision pharmaceuticals and targeted pharmaceuticals in the future. The approved "Lesilacetam Instant Tablet" is based on Aprecia's proprietary ZipDose3D printing technology.

The tablets produced by 3D printing are rich in pores and have a very high internal surface area, so they can be quickly melted by a small amount of water in a short time. Such characteristics have brought good news to some patients with swallowing disorders.
