Abstract

The invention relates to a parallel surgical manipulator capable of horizontally moving three-dimensionally and rotating one-dimensionally, which comprises a first RPRPR closed-loop sub-chain, a second RPRPR closed-loop sub-chain and an actuating mechanism sub-chain. The first RPRPR closed-loop sub-chain and the second RPRPR closed-loop sub-chain are located in the same plane. The first RPRPR closed-loop sub-chain can control a first rotary table to move with two degrees of freedom in the plane, and the second RPRPR closed-loop sub-chain can control a second rotary table to move with two degrees of freedom in the plane. A movable platform can move with four degrees of freedom in a space due to movement of the first rotary table and movement of the second rotary table. The two closed-loop sub-chains are used for controlling movement of the two rotary tables in the plane, and accordingly the movable platform can move with four degrees of freedom in the space. The parallel surgical manipulator has the advantages of compact structure and simplicity in control. All driving rods are connected onto a framework and can be light rods, inertia of mechanism kinematics is low, and dynamics performances are good.
