The invention relates to the technical field of medical instruments, in particular to a flexible minimally invasive surgical instrument device based on gear driving, which comprises an end effector. The end effector comprises a small claw structure capable of being opened and closed, a gear transmission structure used for driving the small claw structure to be opened and closed and a reset structure used for resetting the opened and closed small claw structure, the gear transmission structure comprises a rotatable driving wheel and a driven wheel capable of driving the small claw structure to be opened and closed through rotation, and the driving wheel is meshed with the driven wheel. And the driven wheel is connected with the small claw structure. The invention provides a novel force transmission driving small claw structure to open and close, and because the transmission stability of the force between the gears is higher and flexible, the opening and closing of the small claw structure can be effectively, q
