Sydney: A staff of biomedical engineers in Australia have developed a small versatile robotic that can be utilized to 3D print biomaterials straight contained in the human physique, within the hopes of streamlining future medical procedures.
3D bioprinting is a course of the place pure tissue-like buildings are printed utilizing residing cells and different pure tissues referred to as “bio-ink”, in an effort to restore organ or tissue harm or ruptured blood vessels.
Using residing cells within the printing course of permits these man-made buildings to fuse naturally with the human physique and proceed to develop.
Presently, biomaterials should be created exterior of the physique earlier than counting on sometimes invasive surgical procedure to insert the supplies contained in the physique, which may result in excessive blood loss, infections, and different problems.
Staff chief Thanh Nho Do stated this new system, named F3DB, will remove these problems and dangers by printing straight contained in the physique.
“Presently no commercially accessible expertise can carry out direct 3D printing contained in the human physique,” Do informed a information company.
F3DB includes a three-axis printing head that may bend and twist utilizing hydraulics on the tip of a tender robotic arm. The printing nozzle can print pre-programmed shapes or might be operated manually if extra complicated or undetermined printing is required.
The smallest prototype has a diameter of roughly 11-13 millimetres (mm), just like a industrial endoscope, but it surely might be scaled even smaller sooner or later.
“Smooth robots (are) superb for working with the human physique,” Do, the director of the College of New South Wales Medical Robotics Lab, stated.
“They’ll provide excessive flexibility and adaptableness. This implies they will match to any space contained in the human physique.”
Do believes that the system is on monitor for commercialisation within the subsequent 5 to seven years, pending additional scientific trials.
