Abstract
2-PPTC, a parallel-mechanism-based structure of orthopaedic robot, is proposed after the character analysis of orthopaedic surgery. This structure restricts the active motion-pair into two parallel planes, which forms the boundary of surgical space. The safety of robot system has been guaranteed because of no intersection between the motion space of robot and the surgical space. The position and motion features of the robot have been analyzed using the screw theory. The feasibility of the structure model of this robot in clinical intramedullary nailing therapy of tibial fracture has also been validated, which provides a new method for analysis and design of the application of parallel robot in orthopaedics.
