Provided is a laparoscope-holding robot system for laparoscopic surgery, which belongs to the technical field of robot control and is used to solve the technical problem in the prior art of the operations of a laparoscope-holding robot for laparoscopic surgery being inflexible and same further requiring a doctor to assist in operations. The laparoscope-holding robot system for laparoscopic surgery of the present invention comprises a trolley rack, a surgical tool and a mechanical arm. Since the mechanical arm has at least six degrees of freedom, the mechanical arm can completely simulate the range of motion of a human arm and is no different from the human arm in terms of flexibility, so as to precisely locate the position of a lesion that actually needs to be operated without requiring a doctor to assist in operations.
