This invention provides a magnetically controlled microrobot system and its usage method, relating to the interdisciplinary field of ophthalmic medical devices and magnetically controlled robots. The magnetically controlled microrobot system includes an electromagnetic drive device, a magnetic microrobot, and a control device. The electromagnetic drive device includes a first electromagnetic array and a second electromagnetic array whose magnetic field directions are at an angle. The first and second electromagnetic arrays together form a driving magnetic field that can be controlled in multiple dimensions. The magnetic microrobot includes a magnetic body for responding to the driving magnetic field to perform multi-degree-of-freedom motion and / or posture adjustment. The control device is communicatively connected to the magnetic electromagnetic drive device and is used to control the electromagnetic drive device to generate a target magnetic field to drive the magnetic microrobot to perform the target operation. When used to treat rhegmatogenous retinal detachment, this magnetically controlled microrobot system enables controllable, multi-degree-of-freedom, and precise control of the magnetic microrobot within the limited space inside the eye.
