Technology is growing so fast that now doctors can 3D Print Bones directly in your body without having any problem. This is Amazing! Today we will discuss this topic on ravistech.com. A recent Australian study shows, how a new type of hybrid material can allow a bone marrow transplant to be printed directly inside a patient’s body. In an astonishing step in solving many problems with current bone implants. This process involves the ability to print bones using living cells and without the use of harsh chemicals, both of which are central to modern methods.
Detailed in the research paper published in the journal Advanced Functional Materials, by co-authors of the study Dr. Iman Roohani, a biologist from the University of New South Wales (UNSW) School of Medicine, and Dr. Kristopher Kilian, of UNSW’s School of Chemistry, their procedure use a 3D off-the-shelf 3D printer, and their custom “ink”.
BACKGROUND: BONOR TRANSMISSION PROCEDURES
Currently, the best, most proven method is to replace the autologous graft, in which part of a patient’s own bone is removed from one side of the body. Then placed in a place where a new bone is needed. Unfortunately, this method still has high rejection rates and limits the number of bones that can be harvested in the first place.
Various attempts to assemble a suitable site have been tried, including the use of hydrogels, thermoplastics, or even artificial bio-ceramic “hyper-elastic” bones. However, like an independent graph, they have all encountered a number of obstacles. That is mainly because of the unique combination of living and dead tissue that makes up a normal human bone.
“Bone is a highly mineralized tissue formed at high levels by continuous solidification of the mineral phase within the living matrix where there are cells living in the bones,” explains their research paper, before concluding, “despite recent advances in biofabrication of complex tissue structures, duplication of heterogeneity of small bones has been a major challenge in the formation of biomimetic bone marrow. ”
The process that these researchers say they have pioneered, they say, is different. Doctors can 3D Print Bones which is really awesome.
ANALYSIS: REPRESENTATIVE BONES IN 3D PRINTER that Doctors can 3D Print Bones
To meet this daunting list of challenges; the UNSW team has spent two years completing the calcium phosphate material in biocompatible. That means it will not pose a risk of allergic reactions by the manager. Morever this also creates a soft adhesive at room temperature.
The substance is placed in a gelatin bath or other liquid to mimic the interior of the human body, causing chemical reactions, making it difficult to attach to porous trousers or nanocrystals similar to the bone itself.
“It is truly the first example of a composite that mimics many of the characteristics of native bones and living cells.” says one researcher. Researcher Kris Kilian in a short video highlighting the technique. “This opens up the opportunity where you can directly print the patient’s bone inside the hole.”
Kilian further explains the benefits of this program, explaining that, “during surgery, if [the patient] has a bone that has been re-operated on due to disease, or has had a tumor removed, then we can scan that bone, then insert it into a [sic) 3D printer, and then print directly, within the patient’s space, with its existing cells. And those cells can then connect, forming a natural bone naturally. ”
In that same video, Dr. Kilian sums up the advantages this process offers, all ideally leading to “quicker surgery times, a reduction in suffering, and also hopefully [saving] lots of lives.”
VIEWING: THE FUTURE OF BONES AND 3D PRINTERS
The exact method of the team of researchers is still being developed. Moreover, they have done their experiments successfully with an inefficient 3D printer, especially Hyrel 3D Engine HR. They did, however, equip the device with a custom microphone.
Called the ‘COBICS’ of Ceramic Omnidirectional Bioprinting in Cell-Suspensions, Dr. Roohani says in the future, their process could be modified to work on other types of 3D printers. Including portable and portable types that can be used directly in the stadium. “You will need to upgrade the printer to each system,” he explained in an IEE Spectrum post. “but the concept and goal of this method will be the same.”
Going forward, the team is now in the process of designing a bathtub. That will allow them to print larger bone samples. They are reportedly going to test small animals to see how they accumulate through traditional bone grafting. After that, they reportedly hope to work with dentists, surgeons, and other health professionals to consider specific applications. Possibly co-operate with them in obtaining FDA approval, which the legal agent has already indicated they are willing to consider.
