Robotic system for laparoscopic surgery

摘要

The invention relates to a robotic system for laparoscopic surgery, comprising a supporting structure (230) having at least one arm (210; 220) slidably connected thereto. Each arm (210; 220) includes a first element and a second element (300; 400) hinged to one another. The first element (300) is rotatably hinged to the supporting structure (230) and can rotate about a longitudinal axis (L1), while the second element (400) can receive a hinge having at least two degrees of freedom (550) for the purpose of connecting a tool (900). The longitudinal axis (L1) of the first element (300) is substantially perpendicular to the hinge axis (L2) of the first element (300) and the second element (400). The invention provides a simplified architecture that allows the tool secured to the arm (210; 220) to be moved precisely and effectively.
