A device used for capturing micro-particles, which comprises a pressure regulator, a micro-jet nozzle, and a hydraulic device for providing injection liquid for the micro-jet nozzle; wherein the micro-jet nozzle is provided with an annular jet hole, the annular jet hole having a bottom end, a top end, an inner diameter, an entrance port located at the top end, and an injection port located at the bottom end, the output of the pressure regulator is connected to the entrance port of the micro-jet nozzle. Compared with the prior art, in the present invention, the liquid is taken as the medium, a kind of upward support on the micro-particles and a flow-around lift force perpendicular to the jet direction are generated by the micro-jet nozzle with the annular jet hole, which jointly act on the micro-particles, so as to achieve the micro-particle capture.
