Application: Three dimensional robotic bioprinter (Patent ID: US20240156492A1)
The patent filed by Medtronic Plc describes a minimally invasive system that utilizes a surgical robot as a three-dimensional printer to fabricate biological tissues inside a subject's body. The system involves a preoperative plan that directs the robot's motion and bio-ink extrusion to create tissue layers with desired thickness and dimensions. Different types of bio-inks can be used to create composite elements, and the system includes a small-diameter bio-ink ejecting mechanism, such as a piston-driven cannula, for access to confined spaces like joints. The robotic control is programmed for angular motion around a pivot point at the insertion site, and bio-inks can be stored in layers within the cannula for sequential dispensing.
The patent's claims detail methods for determining an operative plan for the surgical robot, including obtaining preoperative images, calculating trajectories for bio-ink ejection, and inputting the trajectory into a controller for autonomous tissue formation. The claims also cover determining planned robot motion, using artificial intelligence for trajectory calculation, and considering factors like avoiding damage to tissues and forming the tissue element efficiently. Additionally, the patent describes configuring the surgical robot system to form tissue elements by layering bio-inks within the cannula based on predetermined compositions and amounts. The method also involves manipulating the cannula to follow a trajectory for tissue generation, with external imaging used to verify the process.
