In recent years, with the rapid development of 3D printing technology, its application in health care is also broad. Previously, the application of 3D printing in the field of healthcare was mainly to construct models. Today, this technology has rapidly spread in the field of life sciences, including personalized surgical implants, scaffolding and tissue regeneration.
According to a study by British market research firm Visiongain, the total 3D printing market in healthcare will reach $4 billion by 2018. Perhaps the most famous company to apply 3D printing technology to biomedical sciences is Organovo, a publicly traded company based in San Diego, USA that uses cells as "bio-ink" to make active human tissue pieces through a 3D printing process.
Here are a few examples of healthcare 3D printing applications that researchers and startups are exploring with great interest and energy.
1 nerve cell regeneration
A research team at the Michigan Institute of Technology is using 3D printing for nerve regeneration. By constructing a mother and cultivating nerve cells with full functions, this idea aims to re-implant these hard-to-regenerate cells into the human body. Tulu-Sakufa, director of the Nanomedicine and Nanoelectronics Laboratory at Michigan Technological University, participated in the project, saying that the technology will help the nerve tissue of injured patients with spinal cord injury to regenerate. The researchers used a desktop printer-sized 3D printer to use cell-membrane nanocrystals as bio-ink, and added graphene to transmit electrical pulses to print out the bio-skeleton.
2 reduce the cost of prosthetics
The 3D printing startup Project io is committed to improving the prosthetic assembly process by scanning the patient's residual limbs and creating tailored models. By launching a prosthetic development app that can be installed on iPads and other similar devices, the startup said it is "democratizing 3D technology for the mass market." The online community e-NABLE is also doing similar work, many people in this virtual community. Join forces to use 3D printers to create prosthetic limbs for those in desperate need.
3 micro-robot for drug delivery
Swiss researchers are developing micro-robots that deliver drugs in the human body. Through the research and development efforts of Bradley-Nielsen, professor of robotics and intelligent systems at the Federal Institute of Technology in Zurich, and Christopher, a professor of microsystems and nanosystems, these micro-robots can be used to improve minimally invasive surgery, targeted medication, remote sensing and single The effect and level of cell manipulation. These micro-robots are designed to work like flagella so that they can be digitally manipulated to deliver the drug to a designated part of the body.
4 develop a surgical plan
One of the simplest applications of 3D printing in the healthcare field is to help develop surgical plans or assisted surgery. It can scan and print out 3D models of internal organs of the human body, allowing medical staff to practice their hands repeatedly.
Beijing Fuwai Hospital applies this technology to cardiovascular interventional surgery. Fuwai Hospital cooperated with Belgium 3D printing service provider Materialise to create a heart model and carry out fine surgery training to improve the success rate and effectiveness of the surgery. Materialise Chairman Peter-Ress said in a statement, "This is more obvious when performing surgery on infants with congenital heart defects, because they are very young and fragile, and the surgery becomes more complicated and finer.
