corybroo Posted August 12, 2020 Report Share Posted August 12, 2020 This sounds like science fiction. New microrobot with in situ, in vivo bioprinting offers promise for gastric wounds Bioprinting—delivering new cells directly to the wound site to repair the tissue—offers a potentially very useful way to treat the problem. "The difficulty is that current bioprinting technology focuses on external sites. Bioprinters are normally quite large, and cannot be applied to inner tissue repair without invasive surgery to give enough room for the printing operation. To overcome this, we developed a microrobot that enters the body via an endoscope to carry out tissue repair inside the body." The bioprinting platform … is a Delta robot composed of a fixed base, moving platform and three identical kinematic chains. To be as minimally-invasive as possible, it can fold itself down when entering the patients' body, then unfold before beginning the bioprinting operation. A 10-day cell culture showed that printed cells remained at a high viability and a steady proliferation, which indicated good biological function of the cells in printed tissue scaffolds.
