Abstract
A miniature bone mounted robot configured to perform minimally invasive orthopedic surgery coupled with regenerative three-dimensional bio-printing technology to restore cartilage and affected bone. The robot uses a sensor device attached to a holder affixed to the robot activated arm, to map the three-dimensional surface of the bone surface to be treated. The sensor may be a touch sensor, an optical imaging device, or another tool for mapping the bone surface. The robot shapes and prepares the bone surface and subsequently deposits a bio-ink implant in a three-dimensional pattern mimicking the original shape and depth of the articular cartilage. Because the entire procedure is conducted through the robotic platform rigidly mounted on the patients bone, there is no need for registration to preoperative three dimensional images, or for intraoperative tracking. Cell deposition based on mapping of the actual three dimensional anatomy, ensures an optimal outcome.
